FIELDThe present disclosure relates to an event timing system and, more specifically, to an event timing system including a location tracking system for tracking the timed participant or object throughout the timed event.
BACKGROUNDThe statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
When using a radio frequency identifier (RFID) system or similar detection technology system for timing sporting events, it often desirable to track the progress of a participant. In current systems such as those used in marathons, an RFID tag reader is setup at the beginning or starting line, and one or more mid-points was waypoints such as at various distance location along the route of the marathon. Another final RFID tag reader is located at the finish line to provide the determination of the participant's time for traversing the marathon course.
Other systems, not used in current sport timing events, can track a location of an objection by using a GPS receiver that receives geodetic location data from a plurality of orbiting GPS or GIS satellites. These GPS receivers are often used in vehicles and can be handheld, but are not designed or suitable for use in most timed events such as running races. Furthermore, these GPS receivers often know their own location within a certain accuracy, and have been implemented in modern smart phone technology. These smart phones include a GPS receiver and can be program with software programming in an “app” for providing location data via the application to remote systems. However, the carrying and use of smart phones are not practical for use by event participants, especially where harsh conditions or water are present. Furthermore, these smart phones are not adaptable for use by a participant or an event organizer for integration with event timing systems and are themselves not accurate enough to be used for determining a participants event time.

The TS LDS 120 enables an object or a participant 110 to wear a small lightweight location tracking device or tracked location device 130 (LA) such a GPS receiver, cellular triangulation receiver, cell phone or the like, while traveling a predetermined course or timed track 114. The TS LDS 120 will store location data points every 1, 5, 10, or 30 seconds as determined by the user. The location data (LD) is collected from up to 8 satellites that the LA receiver 130 may lock onto when the user 110 is wearing the device 130. The LA device 130 has memory that is capable of storing thousands of location data points such that a user could participate in a Marathon or perhaps a Triathlon that lasts for hours. The LA 130 operates on a small battery or other power source or can utilize power conservation as will be described below. As the LA tag 130 for each participant 110 comes within a wireless range of a Location Detection System 120 (LDS) that may or may not be equipped with an RFID tag reader 104 (TRS) for reading the 5 to 10 feet of a TS 102 component such as TRS 104 equipped with a LDS 120, the location data LD is requested or otherwise transmitted from the participants LA tag 130 to the local LDS 120, and subsequently to either the coupled TRS 104 or directly to the TS 102 via the TS NET 140, as shown in
The presently disclosed system 100 provides a timing system 102 and the user of such system the ability to collect the location data LD on a small device associated with the participant 110, and then wirelessly transmit that location data LD to the location data detection or collection systems (LDS) 120 stations along an event course. In addition, the disclosed communication protocol enables the TS system 102 to receive such participant location data LD, and to provide or make available such location data to users and/or systems desiring such participant location data.
In another embodiment, a Location Tracking device or tracked location tag device (LA) 130 has a GPS or other location receiver (could be cellular triangulation or the like such as a local system) with corresponding first antenna; a process; a memory; computer instructions/software with a database or data storage format; a battery; a housing possibly with an on-off switch, an indicator LED for user visual on or low battery indicator; a second antenna; and a wireless transceiver coupled to the second antenna, and operating at a predetermined wireless operating parameters (frequency, protocol, etc.). The LA 130 regularly receives timing signal, (may be an external GPS/location signal in one embodiment if such were available to this unit), receives/determines a plurality of time stamped location data LD of the participant 110, e.g. TSLD 120 including the LsubNs, time stamps them, and stores them in the memory. Each LA also includes a LA Identification data that is transmitted with each for uniquely identifying the LA and possibly participant data or identification, etc.
In some embodiments, the LDS 120 includes interfaces each having an antenna and a wireless transceiver coupled thereto and being communicative with the LA wireless transceiver (compatible operating parameters). The Interface consistently transmitting a read request for requesting a transmission from any LA 130 within the wireless range of the LT TS Interface. The Interface receiving the data including at least a portion of the TSLD data. Could be all or that which is new since the last read or a clean dump each time. The wireless transceiver is always on for detecting a read request from a LT TS Interface. The LTTSI transmits the received TSLD to a TS 102.
In some embodiment the TS 102 receives the LDS 120 received location data including the LA ID/Participant ID and stores the LD in a memory for each participant. The TS system 102 formats the LD data for each participant 110. The TS system 102 includes an API with a protocol that has a Request LD message that includes a participant ID and can respond with a Provide LD message that includes the TSLD data with the participant ID to the requesting entity.
When a chip is read along the course, we then send out a message to the GPS unit to dump it's memory to us over a packet protocol we have design. The packet is actually quite simple because we don't want much overhead given that the person running by isn't within view for long.
Another exemplary embodiment process/method:
a. RFID Tag/Chip read occurs on the RFID tag by the tag reader detection system (DS). Once this RFID tag is read, the TS 102 determines the tag ID of the object or participant that is approaching the detection point (DP) 112 that is equipped with a LDS 120, such as 50 to 75 feet before the actual DP 112.
b. The TS 102 notifies the LDS 120 of the approaching tag number, and the LDS system 120 communicates with the LA 130 for that approaching participant 110. The window for this can be between 3 to 10 seconds in a typically running timed event where a short-range low power wireless technologies is used for communication between the LDS 120 and the LA 130.
c. The TS LDS 120 issue a request (JGPREQ) to the LA 130 of the object using the tag id in the request. This request can be to have the LA 130 transmit all timed location data points within its memory back to the requesting TS LDS 120.
d. After the TS LDS 120 receives the requested location data from the addressed LA, the TS 102 can send a Clear Memory command to free up the memory in the GPS unit. (JGPCLM) or if on a portion need to be cleared a command with a percent indicator (JGPCLMXX) where XX represents the percentage of memory to clear, starting with the oldest records in memory. This is useful if the operator wants to only clear the first set of records that have been read by perhaps 2 or 3 stations earlier along the course. By having a rolling memory clear, we can ensure that the LA unit 130 is read by multiple stations and we are clearing out the oldest data periodically to make room for the new information being gathered.
A Requesting Entity (RE) is coupled to the TS 102 via a data communications network 140 using a protocol as described herein. The requesting entity can be a Kiosk 170 or an Announcer and the app sends the request and then processes the received Provide TSLD message and data for various uses such as a display on a map of the event, or transmitting such or display on a GUI etc.

The TS NET system is suitable for use with the herein described STIIS is an event communication system that provides real-time statistics and event participant information to computing devices, web sites, cellular phones, television displays and monitors, and other types of communication devices. The capabilities of the TS NET system include, but are not limited to the following: (1) interfaces with existing TS timing systems to provide real-time updates of participant information, images and video, on television displays or monitors, (2) provides event clock screens that can show the elapsed event time updated in real-time, (3) provides real-time updates of times on participants at any point on the event course, (4) provides detailed event statistics which are updated in real-time, (5) includes event reports including, but not limited to, total finishers, total males, total females, top 5 male finishers, and top 5 female finishers, (6) provides real-time updates to web sites with event participant results, (7) includes search capabilities for locating individual or groups of participants within an event, (8) provides the ability to generate custom messages for event participants that are displayed as they cross a detection point on the course, (9) includes the ability to generate custom advertising messages that are shown on an event related display such as an event clock, and (10) provides data storage for event results which can be retrieved at any time during the event and (11) location data of the participant with timings at each location.
When using a sport timing system (TS) using an integrated communication system (TS NET) for timing participants in sporting event, the TS NET system and method makes it possible to view updated participant information including, but not limited to, finish times, bib numbers, and participant names on one or more large displays. The TS NET system also displays a real-time event clock display showing elapsed event time. In addition, the TS NET system provides a real-time update screen of event results that can be used by anyone who is providing event updates over a radio or television station, or who is providing updates over a public address system at the event site. The displays supported by the TS NET system include flat-panel television screens or monitors that are placed at a finish line or in an area where participants or spectators can see the results. The information displayed on the screens not only includes participant results, it also includes custom messages for each participant, as well as advertising messages from event sponsors. Messages and screen displays can be customized by the user to utilize various font sizes, font types, colors, and the placement of information on the screens. Furthermore, the user can modify screen images to include custom artwork and logos and that information will also be displayed as event results are being updated on the television screens or monitors. The TS NET system can also update a web site with event results during the event, thus providing a communications tool for publishing event information over the internet.
The TS NET system utilizes a network to receive messages coming from an TS that may have one or more tag reader or participant detection systems associated therewith. For example, an TS-TS NET communication system enables the sharing of participant and event data among systems in support of sport timing ancillary systems and applications. The TS NET system can receive messages from multiple systems. Thus, numerous detection systems can be placed at many locations on an event course and information from those systems can be transmitted over a network connection to the TS NET system. The network interface for the TS NET system can use a connected or disconnected state-less connection, thus allowing guaranteed or non-guaranteed information delivery, such as a TS-TS NET network interface.
As described herein, an TS NET system utilizes a network to receive formatted text messages coming from a sport timing system. There are two primary types of messages that can be used when communicating with the TS NET system. The first type of message provides the event participant information to the TS NET system. The second type of message provides for time synchronization to make sure that the TS NET system is using the same time standard as used by the other TS and TS-TS NET communicating systems at the event. The message format for the TS NET system supports variable length messages that can be customized by the user. The information can be transmitted via numerous technologies including, but not limited to, wired networks, wireless networks, satellite networks, cellular networks, serial networks, or private networks. The messages can be transmitted over any type of network communications protocol including, but not limited to, TCP/IP or UDP, or as generally defined herein by way of example as TS-TS NET.
The TS NET system listens for messages on an IP address and socket number defined by the user in a configuration screen. Once this has been done, the system listens on the designated IP address and socket for inbound messages. When a message is received, it is processed by TS NET. Depending on the configuration of the TS NET system, real-time displays may be formatted and updated with participant or event information. In addition, web site updates may be completed, and reports may be updated, email messages formatted and sent, text messages formatted and sent, and images and videos transmitted and displayed by display devices.
The message type indicator at the beginning of the information packet determines the action taken by the TS NET system. Participant specific messages will contain the ANNC indictor that contains participant data/information. The end of each message or information packet should always contain an end of message delimiter, for example, as described herein an EOM “|” indicator to ensure that the end of packet can be identified by the TS NET system. In addition, the “|” character should be used to indicate the end of each field within the information packet. There are no limits on the length of a field within the information packet. Thus, the system can transmit a significant amount of event and participant information within a single message, and can include image and video links or even files.
While the TS NET system was designed for sporting events, it could be used for any number of other applications that may be associated with multiple detection systems having to work interactively together for a common purpose. Furthermore, while the TS NET system will be described in conjunction with the current embodiments, it will be understood that they are not intended to limit the TS NET system to these embodiments. On the contrary, the current design is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the TS NET system.
The TS-TS NET interfaces can include a pair mated datagram messages including a requesting and receiving location data.
In yet another embodiment, a method for communicating real-time sporting event and participant announcement information received from a sport timing system (TS), the method including receiving, at an announcement interface system having a processor, a memory, a first data interface communicating over the a stateless packet data communication network with the sport timing system, receiving a multicast datagram location request and read messages including an identification of the sport timing system and participant data including a participant identifier for uniquely identifying each participant in the sporting event and participant timing data. The method also including formatting, in the announcement interface system, the received portion of the participant data into an announcement system message having a predetermined data format. The method further including transmitting, at a second interface of the announcement interface system communicating with an announcement system, the announcement system message including the participant data, the participant identifier, and participant timing data and the participant location data.
The TS-TS NET facilitates and streamlines the communication of tag reader or participant detection system timing information between multiple computers used at sporting events. The protocol is flexible and adaptable and can be used to transmit any type of information across any type of network. The use of variable length messages makes it possible to customize the messages sent or received from any type of device. The protocol is simple and efficient and can be quickly implemented.
The foregoing descriptions of specific embodiments of the present design have been presented for the purposes of illustration and description. They are not intended to be fully exhaustive or to limit the design to the precise use, form, or methods disclosed, and it is obvious that many modifications or variations are possible in the light of the information provided above. The embodiments were chosen, shown, and described in order to best explain the concepts and principles and the practical application of the design, thus providing others skilled in the art the ability to best utilize the design and various embodiments with various modifications as are suited to the particular use desired.
The Timing System (TS) Interactive Communication System and Method (TS-TS NET) as described herein has both text files and network interface files.
TS-TS NET can have text files that a user or TS system developer can access for creating TS-TS NET compatible systems or applications.
In addition, a network interface provides an ability to communicate with an TS system such as TS NET in real-time using TS-TS NET. The file interface is very quick and easy to use. The network interface is much more complex and can require experience in writing network applications. In addition, as described herein one skilled in the art of this TS-TS NET network interface and method requires an understanding of any operating systems environments in which the present TS-TS NET system and method are implemented. As such, it is assumed that any person of skill in the art implementing the present TS-TS NET system and method is well versed in such implementing operation system environment.
TS-TS NET can access multiple TS files that are used within one or more of the multiple TS systems including the Chip or TS Output File and the TS Database File. The file formats documented below are subject to change, so please check with us periodically for updates.
An TS system with a coupled participant detection system monitors a detection point and collects the identification of the detected participant and stamps a time of detection for each participant. These are referred by way of example herein as collecting participant and detection data including detection times, which can be written as participant read information to a text file. As described by way of example herein, a “chip” is a timing chip that is associated with a participant in the sporting event. A chip refers to the detection of at particular participant by a particular detection system. While a chip refers generally to an RFID chip and the reader is an RFID reader, those skilled in the art would understand that the reference to an RFID chip or chip, could be any type of tag reader or participant detection at a detection point and still be within the scope of the present disclosure.
An TS system or a user of such TS system can predetermine the name and location for the TS OUTPUT FILE. This file is updated in real-time by the TS system as the event progresses and it contains the following information: Antenna #,Bib #,Bib #,“Time” The file always uses a delimited format, shown here by example using commas as the delimiters, and the time field can be any format, but is shown in this example as having quote marks.
The exemplary format for the TS OUTPUT FILE is readable by a spreadsheet or many third party programs, but other formats are also possible. An TS system can ignore the Antenna # field for many applications as the Antenna # field is often used internally by an TS for uniquely identifying the actual equipment making the detection. The Bib # field appears twice and this is not an accident. This is repeated in this exemplary embodiment as several third-party programs require this format when importing an event timing data file. The final entry is the time of the chip read which is in the format of “HH:MM:SS” or “HH:MM:SS.XXX.” As shown in this later example, the format for chip read times can be expanded to include sub-second timing. TS-TS NET communication systems and methods should properly handle time values that may include tenths, hundreds, or thousandths of a second.
In the TS system, the chip number is generally the same as the bib number worn by the participant. Thus, for an event with perhaps 500 participants, the Bib # field may contain a value from 1 to 500. For larger racing events, the Bib # field can be up to 99999 or even up to 500000 or so depending on the requirements as the TS and TS-TS NET systems will support these expanded field lengths.
The following is a sample of a typical TS-TS NET output file using the HH:MM:SS format:
0,41,41,“14:27:42”
0,47,47,“14:27:44”
0,39,39,“14:27:46”
0,14,14,“14:27:48”
0,32,32,“14:27:50”
Each TS is capable of detecting and reading a single chip or participant multiple times as it approaches a timing detection point. Thus, an output file may contain multiple entries for the same chip/participant. The last entry is the final read on a chip. For example, the following output file shows that a single chip was read multiple times as the runner approached the finish line in an event.
0,32,32,“14:28:20”
0,32,32,“14:28:21”
0,32,32,“14:28:22”
In one exemplary embodiment, the output file only contains one entry since most runners can pass through the detection point in one second or less. However, if an event can have a number of walkers, there may easily be 4 to 5 entries for the same timing chip as the walker approaches and goes past the finish line.
As an TS system or detection system reads timing chips, the TS system appends new data to the file and continues to do so during the event. Thus, the file should not be modified or locked while an event or event is ongoing. It's best to read the file once the event is concluded, or while the system is not actively reading timing chips.
Each TS system coupled with a location data system (LDS) can have a high-speed memory with a binary database that runs in the memory and is updated very rapidly when the detection are made such as when chips are being read. When this database is saved to the disk drive, it is written to a text file using a delimited format, such as delimited using commas. When using commas as the delimiters, the file can be read by third-party programs without having to build a complex database interface as such files are common as known to those skilled in the art.
The following is a sample TS DATABASE file record:
1,Jay_Cooper,08:00:00,08:15:00,00:00:00,00:00:00,00:00:00,08:45:00,00:45:00,50,Half Marathon,M,Allentown,Team Cooper,50001,Club Member,#76435,137
TS can have the ability to automatically write out the TS DATABASE FILE during an event to a file name selected by the TS user. For example, the TS can be specified to have a file written to the disk every 30, 45, or perhaps 60 seconds. In addition to writing the TS DATABASE FILE to the disk, TS can automatically create multiple files that have a unique file name that is based on the current date and time. By having multiple files on the disk, any of the files can be accessed without a concern about TS accessing those files again once they have been created. For example, an TS system can write the database to the disk every 60 seconds with a unique file name. The TS system can specify the base file name as TSDB.txt. When TS writes the file, it creates a file with the following name format:
TSDB20090501100502.txt
There can be multiple TS DATABASE FILES on the disk drive, and there could be hundreds of files by the time the event completes. Each of these files is essentially a unique snapshot of the event results for that moment in time.
The following is the format for the database file:
Bib #,Name,StartTime,Split1,Split2,Split3,Split4,FinishTime,ElapsedTime,Age,Division,Gender,City,TeamName,ChipField,UserField1,UserField2,UniqueID
The Bib # field can contain a value from 1 to 99999 depending on the version of the TS system in use.
The Name can contain the full name and is typically formatted as FIRST NAME LAST NAME with no comma between the first and last name, but may be formatted such as using an underscore or the like. In some embodiments, it is undesirable for particular characters, such as a comma, by way of example, not be included in the name field due to their use as a delimiter where applicable. When an TS system loads the database file, it can use particular characters such as a comma to determine the individual fields. Thus, such TS database delineation characters should not be used in the Name field as such usage can cause TS to use the wrong fields for the remaining entries on the line being read.
The following fields all contain a time based on the time of day: Start Time, Split1, Split2, Split3, Split4, Finish Time. All of these fields are in the format HH:MM:SS or HH:MM:SS.XXX and there are no quote marks.
The described format for chip read times can be expanded to include sub-second timing. Any TS-TS NET implementations should be implemented to properly handle time values that may include tenths, hundreds, or thousandths of a second. Following is one exemplary embodiment of a set of applicable TS data fields:
a) The Elapsed Time field is a calculated field which is typically the Finish Time minus the Start Time. This field is in the format HH:MM:SS or HH:MM:SS.XXX and there are no quote marks.
b) The Age field can contain up to 3 digits typically ranging from 1 to 100.
c) The Division field can contain a text entry that can be up to 250 characters in length, although it is typically 20 or less characters long.
d) The Gender field can contain a text entry that can be up to 250 characters in length, although it is typically 1 character with either an M or F entry.
e) The City field can contain a text entry that can be up to 250 characters in length, although it is typically 25 or less characters long.
f) The Team Name field can contain a text entry that can be up to 250 characters in length, although it is typically 25 or less characters long.
g) The Chip field can be used, in some embodiments, to include a text entry that is associated with a particular timing chip. In some embodiments the Chip field can be up to 250 characters in length, although it is expected to be 6 or less characters long.
h) The UserField1 field can contain a text entry that can be up to 250 characters in length, although it is typically 25 or less characters long. This field may be used by the software to contain values related to team order for relay events. In some cases, the TS user can place information in this field related to the TS user's personal information such as emergency contact number.
i) The UserField2 field can contain a text entry that can be up to 250 characters in length, although it is typically 25 or less characters long. This is a second field that often contains additional personal information about an event participant.
j) The UniqueID field can contain a text entry that can be up to 250 characters in length, although it is typically 10 or less characters long. This field is often used to track event-day registration numbers or other unique values that identify an event participant. TS can automatically insert a unique value in this field during the rapid registration process in the software.
Not only can TS write this TS DATABASE FILE text file to the disk drive, it can read it back in from the TS DATABASE FILE. Thus, a TS DATABASE FILE can be created using this format and TS can read it just fine. Any time fields that are created should be in the HH:MM:SS or HH:MM:SS.XXX format with leading zeros on any times that are less than 10. For example, if the time is 9:10 am, the field should contain the entry 09:10:00 or 09:10:00:000. In most cases, when creating a new file that can be loaded into TS, the time fields should contain 00:00:00 or 00:00:00:000. However, if an event has assigned start times, the start times can be loaded into TS by using the StartTime field.
TS can have a state-less network interface such as provided by a user data protocol (UDP) system as used for outbound and inbound messaging over a suitable communication network. The TS-TS NET system utilizes these messages to include outbound packets using TS-TS NET for READ and ANNOUNCE information, as well as other data as described herein. In addition, an TS using TS-TS NET monitors the Internet connection for UDP TS-TS NET messages from other TS-TS NET systems or third-party programs coupled to the same communication network. This interface allows third-party programs to be developed which can work within the TS architecture.
UDP packets as used by the present TS-TS NET system provide a very quick and relatively easy system to implement and from which to build flexible and robust applications. While there are known limitations for UDP packets, the describes application of the UDP packets in the TS-TS NET recognizes these limitations and adjusts the design and applications accordingly whereby UDP provides a very suitable solution for communicating between multiple TS systems.
The following includes the packet structure for all TS-TS NET supported UDP packets. TS-TS NET can be configured to listen and send on any socket ranging from 5000 to 9999. In addition, TS-TS NET can be set to send to a specific computer by using either the computer name or its IP address. Furthermore, TS-TS NET can send to all computers on the network by using 0.255 as the last bytes in the IP address. Of course in other systems and embodiments other broadcast messaging address can also be used and still be within the scope of the present invention. In this example, if the TS-TS NET is set to 192.168.1.255, the TS-TS NET sends messages as Broadcast packets. TS-TS NET message are sent as clear text contained within the UDP packet, with fields separated by the “|” characters. |EOM| should always come at the end of each message.
As noted, the TS-TS NET network interface is configured for stateless broadcast communications systems, such as UDP using a broadcasting IP address indicator such as 255. The networking interface can however support a variety of different types of messages. These can include broadcast messages, multicast messages and unicast messages, between and among various TS-TS NET systems.
Broadcast TS-TS NET messages are transmitted from the TS-TS NET interface over the stateless broadcast communication network with no addressing as to the intended recipient as well as no identification the TS-TS NET system that is sending or sent the message. As such, each of the Broadcast TS-TS NET Messages can be read by any listening TS-TS NET device, and once received by that device, the receiving TS system does not know which other TS system sent the message. As will be discussed, these include, by way of example, the ANNCM and TRSTART messages.
Multicast TS-TS NET messages are transmitted from the TS-TS NET interface over the stateless broadcast communication network with no addressing as to the intended recipient. However, these messages include an identification of the sending TS system, e.g., FROM identifier. These TS-TS NET multicast messages can be read by any TS-TS NET system and once received by that TS system, the receiving TS system knows which of the other communicating TS systems the message originated. These include, by way of example, the ANNC, ANNCL, READ, NOANNC, TSYNC, RSIG, and KREFRESH messages.
Unicast TS-TS NET messages are transmitted from the TS-TS NET interface over the stateless broadcast communication network with an identification of which the sending entity is (FROM identifier) as well as an identification of the intended receiving TS system (DEST or Destination identifier). These unicast TS-TS NET messages are essentially point to point messaging within a stateless broadcast messaging communication system. Only the identified destination TS-TS NET system should receive these messages and they are ignored by all other listening TS system. The receiving TS system knows that the message was intended for its use and it knows the identification of the sending TS. These include, by way of example, the REANNC, RESEND, LOOKUP, STARTRFID, STOPRFID, COMMAND, RQIMAGE, STIMAGE, RQIDIR, STIDIR, RQISTREAMON, and RQISTREAMOFF messages by way of example.
It should be understood to those skilled in the art that other broadcast, multicast and/or unicast messages can also be developed as an application may require or benefit from the present disclosure, and still be considered within the scope of the present disclosure.
Announce Message (ANNC):
The ANNC packet is sent by TS-TS NET to the network and can be captured by any device that is listening on the network for UDP packets. The message indicates that TS can have read a chip at the location indicated in the From field.
Packet length=variable size
Total fields=10
ANNC|FROM|BIB #|NAME|AGE|GENDER|CITY|TIME|PACKET #|EOM|
The information in this TS-TS NET packet comes from the TS internal database. The packet # is a unique 3-digit value that begins with 1 and continues to 999, after which it wraps around and starts over at 1. This packet # can be used to ensure that all messages are received. If a message is missing, a request can be made to resent that packet. TS-TS NET maintains a circular buffer of past messages for this purpose.
Announce Message for Lap Events (ANNCL):
The ANNCL packet is sent by TS-TS NET to the network and can be captured by any device that is listening on the network for UDP packets. The message indicates that TS can have read a chip at the location indicated in the From field.
Packet length=variable size
Total fields=11
ANNCL|FROM|BIB #|NAME|AGE|GENDER|CITY|TOTAL LAPS|TIME|TEAM NAME|PACKET #|EOM|
The information in this TS-TS NET packet comes from the TS internal database. The packet # is a unique 3-digit value that begins with 1 and continues to 999, after which it wraps around and starts over at 1. This packet # can be used to ensure that all messages are received. If a message is missing, a resend of the packet can be requested. TS-TS NET maintains a circular buffer of past messages for this purpose.
Re-Announce Message (REANNC):
The REANNC packet is sent by TS-TS NET to request a re-send of a particular packet.
Packet length=variable size
Total fields=5
REANNC|FROM|DEST|PACKET #|EOM|
When this TS-TS NET message is used, the packet number should be included as desired from the TS or TS-TS NET buffer. The FROM and DEST fields contain the IP addresses for the two systems.
No Announce Information (NOANNC):
The NOANNC packet is sent via the TS-TS NET when a request was made for a packet that is not yet available. For example, if TS-TS NET can only send 100 packets, and a system requests packet number 120, the system will generate the NOANNC message in response.
Packet length=variable size
Total fields=10
NOANNC|FROM|0| |0|M| |00:00:00|Packet #|EOM|
The message returns the requested packet number with the NOANNC header.
Announce Message Information (ANNCM):

Packet length=variable size
Total fields=4
ANNCM|BIB #|MESSAGE|EOM|
Read Message (READ):
The READ packet is sent by TS-TS NET to the network and can be captured by any device that is listening on the network for UDP packets. The packet is a real-time feed of any reads that are occurring at the particular TS timing system.
Packet length=variable size
Total fields=6
READ|FROM|BIB #|TIME|PACKET #|EOM|
Packet number is a value that begins with 1 and goes to 999. Once it reaches 999, it starts over again at 1. This packet number is used to reference past messages in case a message is lost on the network and a re-send is requested.
Additionally a separate READ message can be used that includes the PARTICIPANTNAME field in lieu of the BIB #.
Resend Message (RESEND):
The RESEND message is sent to any TS system requesting that it re-send a past message. If a message is lost over the network, a request to resend can be made for any of the last 999 messages sent previously. TS-TS NET maintains a buffer with the past 999 messages. Once the 999 position is used, TS-TS NET starts over at position 1. Thus, TS-TS NET is maintaining a circular buffer of messages.
Packet length=variable size
Total fields=5
RESEND|FROM|DEST|PACKET #|EOM|
The Destination field is the TS system that should respond to this request. This is the same name set in the TS Defaults for “My Name” in the networking section. If a request is made for a packet number that has not yet been used by TS-TS NET, a packet response starting with the BLANK field can be received.
Time Sync Message (TSYNC):
The TSYNC message is sent using TS-TS NET to any TS system that is listening for Time Sync commands. This is typically used by TS Remote to make sure the time on the Remote laptop is the same as that on the TS system. There can always be a slight delay in the network transmission, and as such a 0.25 to 0.5 second delay may be added to the time received using TS-TS NET to compensate for the delay.
Packet length=variable size
Total fields=4
TSYNC|FROM|TIME|EOM|
The FROM field is the name set in the TS Defaults as My Name.
Time Sync Message (TRSTART):
The TRSTART message is sent using TS-TS NET to the Kiosk to set the start clock for the event. The start time can be set on a Kiosk using a command in the Configuration screen. However, by sending this packet to the Kiosk, the time can be set remotely from a TS system.
Packet length=variable size
Total fields=4
TSYNC|TIME|EOM|
Remote Signal Message (RSIG):
The RSIG message is sent using TS-TS NET to any system that is listening for RSIG command. This is typically used by TS Remote to make sure the connection over the network is good to TS-TS NET and also to verify that TS-TS NET is scanning and listening for remote entries.
Packet length=variable size
Total fields=4
RSIG|FROM|TIME|EOM|
The FROM field is the name set in the TS Defaults as My Name.
Refresh KIOSK Message (KREFRESH):
The KREFRESH message is sent using TS-TS NET to any system (typically a Kiosk) that is listening for the KREFRESH command. This is typically used by TS-TS NET to send out all of the results in an event to the Kiosk. This might be useful if the Kiosk re-booted or if the Kiosk was started after results had already occurred in an event.
Packet length=variable size
Total fields=10
KREFRESH|FROM|BIB #|NAME|AGE|GENDER|CITY|TIME|PACKET #|EOM|
The information in this TS-TS NET packet comes from the TS internal database. The packet # is a unique 3-digit value that begins with 1 and continues to 999, after which it wraps around and starts over at 1. This packet # can be used to ensure that all messages are received. If a message is missing, a request that packet be re-sent can be made. TS-TS NET maintains a circular buffer of past messages for this purpose.
Lookup Message (LOOKUP):
The LOOKUP message allows a device to request event information from another device. The identifier may be any text. In most cases, the identifier will be a tag serial number, event bib number, participant name, or perhaps a unique identifier that refers to a particular type of information. For example, if a TS systems needs to know the current duration of an event, the LOOKUP message could be sent to a TS system that is responsible for tracking the total event time. The identifier field might contain the text entry “EVENTTIME” and this entry could be used to indicate that the event duration is desired. The packet number field is optional and if not used, the field could contain a single space.

Total fields=6
LOOKUP|FROM|DEST|IDENTIFIER|PACKET #|EOM|
Start RFID Message (StartRFID):
The StartRFID message is sent to a TS system to indicate that it should start performing a specific RFID function. If the function is to begin at a certain date or time, the TIME field could contain that information. This field could be used to initialize and start a remote RFID system so that it begins to read tags. As also, as used here this is specific to RFID readers. It should be understood to those skilled in the art, that other reader or detection systems are possible and in such embodiments, other messages can be developed or this message can be adapted for their use. Other systems could include: laser detection, video detection, etc. As such, this message could alternatively be: StartDETECTOR, or StartLASER, or StartVIDEO. by ways of examples.

Of course those skilled in the art will understand that when other technology is used for the tag reader or participant detection system, this message can be renamed and still be within the scope of the present disclosure.
Stop RFID Message (StopRFID):
The StopRFID message is sent to a device to indicate that it should start performing a specific RFID function. If the function is to begin at a certain date or time, the TIME field could contain that information. This field could be used to initialize and start a remote RFID system so that it begins to read tags. Other systems could include: laser detection, video detection, etc. As such, this message could alternatively be: StopDETECTOR, or StopLASER, or StopVIDEO. by ways of examples.

Of course those skilled in the art will understand that when other technology is used for the tag reader or participant detection system, this message can be renamed and still be within the scope of the present disclosure.
Command Message (COMMAND):
The COMMAND message is sent to a TS system to request that a particular command be executed in that TS system. The IDENTIFIER field may contain any text desired. This field could be used to send any tag reader or participant or tag detector command to a remote device. For example, if the current battery charge level on a remote system needed to determined, a Command message could be sent with the text BATTERYSTATS in the IDENTIFIER field. The remote system would need to have functions built in that can process the command.

Total fields=6
COMMAND|FROM|DEST|IDENTIFIER|PACKET #|EOM|
Request Image Message (RQIMAGE):
The RQIMAGE message is sent to a device to request that a particular image be returned. The message is useful when interfacing with a system that contains photographs or other pictures such as logos or artwork. The IDENTIFIER field should contain a unique descriptor for the image desired and may contain any text desired. Typically, this field will contain a unique number for a participant in an event. However, the IDENTIFIER could also contain a specific location on a remote system where a file is located. The COMPRESSION field may be used to specify the format of the image to be sent. If higher performance across a network is desired, this field might be used to indicate that High compression is desired. The field may contain any text that is recognized by the system designated as DEST. The PACKETSIZE field should contain a value indicating the maximum packet size to send at one time. Given that most images will contain more data than is able to be sent in a single packet, this field may be used to control packet size, thus tuning the network performance. The PSOCKET field is used when it necessary or desired to have multiple packet streams being sent simultaneously from the DEST. For example, the field could contain 7000 on one packet and 7001 on a different packet to indicate that two streams are being used simultaneously.
Packet length=variable size
Total fields=9
RQIMAGE|FROM|DEST|IDENTIFIER|COMPRESSION|PACKETSIZE|PSOCKET|PACKET #|EOM|
Image Sent Message (STIMAGE):
The STIMAGE message is sent from a system responding to a request for an image, e.g., RQIMAGE. The IDENTIFIER field should contain the unique descriptor for the image that was requested and may contain any text desired. Typically, this field will contain a unique number for a participant in an event. However, the IDENTIFIER could also contain a specific location on a given system where a file is located. The COMPRESSION field indicates the type of compression used on the image when it was sent. If higher performance across a network is desired, this field might be used to indicate that High compression is desired. The PACKETSIZE field should contain a value indicating the length of the portion of the image just sent. Given that most images will contain more data than is able to be sent in a single packet, this field will be used to indicate how many bytes have been sent. The PSOCKET field contains a value indicating which stream the information is being sent on. This may be used when it necessary or desired to have multiple packet streams being sent simultaneously from a system. For example, this field could be used to send individual photos to different computers on a network at the same time.

Request Image Library Contents Message (RQIDIR): The RQIDIR message could be sent to a device to request that the names of all images available be provided for that system. The message is useful when interfacing with a system that contains photographs or other pictures such as logos or artwork. The IDENTIFIER field should contain a unique descriptor for the type of images desired or a filter mask for the names or locations of images. For example, the IDENTIFIER might contain the text entry *, or it might contain a qualifier such as *.JPG is the user only wants to receive a list of images that are in JPG format. Of course other qualifiers may be used for other formats.

Image Library Sent Message (STIDIR):
The STIDIR message is sent to one or more systems as a response to an RQIDIR message and it includes a list of images available. The FILELIST field will contain a list of images in text format that are available. Each image name will contain a carriage return line feed indicator at the end of the name. If the list has been completely transmitted, a final indicator at the end of the list will include an entry of EOL followed by a carriage return line feed. This indicator means there are no additional packets being sent and the entire list has been provided.

Total fields=6
STIDIR|FROM|DEST|FILELIST|PACKET #|EOM|
Request Image Message (RQISTREAMON):
The RQIDTREAMON message is by a TS system to request that a particular image stream be enabled for a real-time video feed. The message is useful when interfacing with a system that contains a camera displaying live video. The IDENTIFIER field should contain a unique descriptor for the image stream desired and may contain any text desired. Typically, this field will contain a unique name for a camera or video interface. However, the IDENTIFIER could also contain a specific socket, URL, or other indicator that is a live video stream. The COMPRESSION field may be used to specify the format to be used when sending the video stream. If higher performance across a network is desired, this field might be used to indicate that High compression is desired. The field may contain any text that is recognized by the system designated as DEST. The PACKETSIZE field should contain a value indicating the maximum packet size to send at one time. Since the video stream will contain a great amount of information, the image stream can be deconstructed into small packets that are sent across the network. The PSOCKET field is used when it necessary or desired to have multiple packet streams being sent simultaneously from the DEST. For example, the field could contain 6000 on one packet and 6001 on a different packet to indicate that two streams are being used simultaneously. The TIMEOUT field can be used to indicate how long, in seconds, the stream should be kept alive. If this value is set to 0, the DEST will continue to send the stream until a RQISTREAMOFF message is received.

Request Image Message (RQISTREAMOFF):
The RQISTREAMOFF message is sent by a TS system to a request that a particular image stream be disabled. The IDENTIFIER field should contain a unique descriptor for the stream to be disabled. The PSOCKET field can also be used to identify a particular socket, in the event that multiple streams are being sent at the same time.

In other embodiments, the packet formats can vary from that described above and herein and still be within the scope of the present disclosure. For example, some or all of the timing system database fields is sent when most of the packets are sent. In such embodiments, this can allow applications to have all of the data contained in a record in the database.
GPS Wakeup Message (GPSWAKE):
The GPSWAKE message is sent to by a TS system to a TS or TRS system or GPS chip to request that a communication session begin related to a GPS read or determination. Receipt of this message by a GPS enabled GPS chip or GPS chip reader system (TRS) to send back parameters for the session in the buffer that sensed and received the GPS data from the GPS chip. The LSOCKET value can be used to identify a unique socket being used for the session. The SETTINGS value is used to request the TS or TRS conform to specific parameters for the session. Once a session is established, the requesting entity will wait for data to show up in the buffer and process it accordingly. Thus, this message is sent to a GPS enabled TRS when setting up a long-term session where GPS read data will trickle in over time, into the Buffer allocated.

GPS Wakeup and Receive Message (GPSRWAKE):
The GPSRWAKE message is sent to TS or TRS system or GPS chip to request that a communication session begin with GPS data being returned immediately. This message causes the GPS enabled chip or GPS enabled TRS system to send back GPS location and possibly also the time information in the GPS reader or TRS system having received the message and having had at least one GPS chip being detected by such system. The LSOCKET value can be used to identify a unique socket being used for the session. The SETTINGS value is used to request the TS or TRS system conform to specific parameters for the session. Once the initial data has been received by the requesting entity, the session will remain open and wait for additional data to appear in the buffer of the requested entity. This command differs from the GPSWAKE message since the GPSWAKE does not request data, but only activates the GPS enabled TRS system to wait for the next available GPS read data, when it occurs, e.g., the GPSWAKE message waits for data to show up. In contrast, the GPSRWAKE message requests that all GPS data be sent immediately by the receiving entity, thus clearing the buffer of the receiving entity such as a GPS enabled TRS or the GPS enable chip itself.

GPS Receive Message (GPSRMESS): The GPSRMESS message is sent to TS or TRS system or GPS chip for GPS chip data reading to request that all data be transmitted immediately by the receiving system. This is a stateless message that does not require a session to first be created between the requesting and receiving entities. Therefore, the GPSRMESS message can be used in situations where rapid communications with a GPS or SGOS TRS system requires, such as a verification of a prior read or in a situation the requesting TS system determines from other facts or factors. The LSOCKET value can be used to identify a unique socket being used to receive the data. The SETTINGS value is used to request the TS or TRS system to conform to specific parameters for the data transmission. BUFFER will contain the actual data coming back to the caller.

GPS Re-Send Message (GPSRSMESS):
The GPSRSMESS message is sent to a TS or TRS system or GPS chip to request that the data previously sent, be re-transmitted. This message can be used to retrieve data that may have been lost in route from the requested entity (another TS or TRS system or GPS chip) to the requesting entity such as another TS. This is a stateless message that does not require a session to first be created. Thus, it is ideal for rapid communications with a chip or system. The LSOCKET value can be used to identify a unique socket being used to receive the data. The SETTINGS value is used to request the chip or remote system conform to specific parameters for the data transmission. BUFFER will contain the actual data coming back to the caller.

GPS Waypoint Message (GPSWAYP):
The GPSWAYP message is sent to a chip or remote system to request specific data that is based on a specific or range of waypoint values. This is a stateless message that does not require a session to first be created. Thus, it is ideal for rapid communications with a chip or system. The LSOCKET value can be used to identify a unique socket being used to receive the data.

GPS Send Message (GPSSENDS):
The GPSSENDS message is sent to another TS or TRS system or GPS chip to transmit GPS data be sent immediately. This message requires you to first create a session. The TSOCKET value can be used to identify a unique socket on the remote system. The SETTINGS value is used to request the chip or remote system conform to specific parameters for the data reception. BUFFER will contain the actual data being sent. The advantage to using the GPSSENDS message is that the remote system will automatically handle error handling for lost messages that did not arrive.

GPS Close Message (GPSCLOSE):
The GPSCLOSE message is sent to another TS, or TRS system or GPS chip to inform it that transmissions regarding GPS location data are now over and the sockets being used for GPS location data have been released. The TSOCKET value can be used to identify a unique socket on the remote system. This message is used for sessions that are always open as described above, for example, GPSWAKE, GPSRWAKE.

GPSCLOSE|FROM|DEST|LSOCKET|EOM|
The GPSSENDC is used to send data to another system, which could be any device including a laptop computer, network file server, or another RFID reader. We also have the GPSSENDS message as well. The only difference is that the GPSSENDS message is used for session-oriented communications where the remote system is able to process packets and look for errors that can cause it to send a message back letting the sender know that the data didn't arrive correctly. The GPSSENDC doesn't require a session and it looks like a UDP datagram and is a connectionless packet. This makes it faster and easier to work with, but it doesn't have any built in error correction.
The buffer field contains information related to the GPS data. In fact, the buffer could also contain RFID information as well. For example, a basic message buffer might have something like the following GPSnumber, Total Satellites, Uptime, Longitude, Latitude, Offset, Current Time, and Elevation. The buffer is free-form text meaning the user can implement their own formatting within the buffer to determine delimiters between the data elements. As an example, a TS might use the # character to designate the end of each field within the buffer. Thus, I might have a packet that has a buffer containing something like: 34.56575#121.456487#18:00:03#0.564#234
Any known GPS receiver ID can also be transmitted with the GIS location data.
In one embodiment, the GPS data is sent without waiting for the remote system to setup a connection socket. This is because in future implementations, we will be using multiple VPN ports to send messages back to ITS or perhaps any other system. Presently, the system here at ITS listens for any and all messages on a common socket. Soon we will allow the user to designate a socket in real-time as they wish to have data sent to a system. The GPSSENDC message will be used for that purpose and when the receiving system collects a packet with the GPSSENDC header, it will parse the buffer to look for specific information regarding the desired communication parameters coming from the sender.
One example, of the waypoint message GPSWAYP, is where there may be a timing point along the course needs to collect data from the chips on the runners and the race has 50,000 participants in it. Now assume this timing point is at mile 5. There will be thousands of runners coming through that timing point very rapidly, thus the density will be very high. If the TS tried to collect every GPS data point from them, it would take a while (relative term) to collect the data for every 2 feet of resolution. During the first part of the race, it is less likely to need or track the runner's position every 2 to 3 feet. Most situations you can have data for every 50 to 100 feet. Thus, this message GPSWAYP allows the TS to tell the chip on the runner that we don't need all of the data, just a portion of it. The communications are much faster that way and we can handle very large densities of runners. The Settings is a free-form field that can be customized by the user. However, it is also possible to send a message such as: GPSWAYP|FROM|DEST|LSOCKET|Res:10|BUFFER|EOM| The value of Res:10 could mean to send us the data point for every 10 seconds from the GPS information collected. Thus, let's say the runner was on the course so far for 20 minutes and this is the first time we are collected the positional data, we will be asking for 6 samples per minute×20 minutes=120 pieces of data. A GPS receiver can provide data down to 100th of a second and thus if we simply requested all data, we might have thousands of data points and that would take a long time to send from the runner's chip to the timing system. So, the GPSWAYP message allows the TS to decide how much data it will need and this can be change changed in real-time based on the density of runners the TS is seeing from the GPS reads.
The process of sending an acknowledgement could also be added. This could be something like GPSACK: GPSACK|FROM|DEST|LSOCKET|BUFFER|EOM
In other embodiments, the process of sending an ACK requires more round trip time, which is not good when dealing with high densities of packets. This is much like the old UDP vs. TCP/IP argument. TCP/IP has the advantage of being a session protocol that has error correction through ACKs. UDP is much faster for sending bulk data because it requires no ACK. For the TS, it may be desirable to dump the location data rapidly to a TRS, LDS or TS without having the overhead of the ACKs. So, I think it would make sense to go ahead and add the ACK message in our spec. Thus, here is the format we will use:
The buffer will contain a response code which will likely be a value of 0 for failure and 1 for success. The TS could also use other values such as 2 or 3 for error handling.
In another embodiment a display system or remote monitoring system may want to display something like a moving map image of where the runner has been. In such embodiments, the remote system can send a GPSRMESS message to a file server or database or computing device that has stored all of the GPS data for one or more participants. When the message is sent over, the buffer will contain identifying data for determining what will be sent back to the requesting system. So, the requesting system, such as Announcer, may have something like the following in the buffer: REQALLGPSDATA:543. This could mean that system wants all GPS data stored in a database for bib number 543. In other cases, the remote system could also send the following in formation in the buffer: REQTIMERANGEGPSDATA:543 and that might mean to send over all data within a time range for bib 543.
