Air monitoring system and method
An environmental monitoring system and method is disclosed. The system includes one or more environmental measuring instruments, a controller in communication with the one or more environmental instruments, and a device located remotely from the controller capable of displaying data generated by the one or more environmental measuring instruments.
The present invention relates to the monitoring of environmental and air quality, for example, at construction sites, demolition sites, remediation sites and emergency sites.
Monitoring air and environmental quality has become an important procedure. Consider, for example, the importance of monitoring air quality in downtown New York City where numerous people have become ill in the last five years. Today's systems provide limited information, and are unable to both control stations and remotely review data in a way to be able to make decisions quickly.
Accordingly, new and improved systems and methods for monitoring air quality are needed.
SUMMARY OF THE INVENTIONThe environmental/air toxic monitoring system (EA-Tox System) of the present invention provides for the real-time monitoring, continuous data logging, and control of a plurality of communications-enabled monitoring instruments on a given site. In accordance with one embodiment of the present invention, up to 125 instruments can be provided per computer port. The system of the present invention can interface with a variety of instruments from a single control unit. In accordance with one embodiment this interface is provided via a serial communications capability. The system and method of the present invention can also calculate a variety of user-defined statistics while data logging, and providing real-time, usable data for immediate use. It further provides users with remote access to logged data and can communicate user-defined situations such as exceedences via telephone, email, computers, PDAs or other devices/media. It can also provide historical monitoring capabilities.
The environmental/air toxics monitoring system, in accordance with one aspect of the present invention, includes multiple components: The Instruments/Data Pool; The Communication System; The Control Unit (the nexus of the EA-TOX SYSTEM); Remote Access; and Annunciators, as shown in
The Instruments/Data Pool
The EA-TOX SYSTEM can interface with a variety of environmental monitoring instruments equipped with “serial” type communication capability. Of course, the system of the present invention can also interface with instruments having different types of communication capabilities, such as parallel communications, wireless communication and any other type of communication protocol. The EA-TOX SYSTEM is capable of operating a many different types of environmental/air toxics instrument types (e.g gas, vapor and particulate air monitors, radiation detectors, water monitors, weather detectors) and various types of instrumentation models and brands.
The Communication System
In accordance with one aspect of the present invention, the EA-TOX SYSTEM is highly flexible, with user-adjustable settings for most communications parameters. This allows the user to avoid restrictions that may exist due to hardware limitations associated with specific instruments by modifying settings and parameters. As such, the Communication System can consist of almost any hard wired or wireless serial communication system.
Control Unit
In accordance with another aspect of the present invention, the Control Unit consists of an IBM-compatible computer or other computer meeting minimum hardware specifications and operating the EA-TOX SYSTEM software of the present invention. The EA-TOX SYSTEM software is an integral part of the EA-TOX SYSTEM. It provides the graphical user interface (GUI) between users and instruments; facilitates communications between the Control Unit and the instruments; logs data to the database; performs real-time averages and other statistical calculations; permits varying degrees of remote access; and sends notifications and alerts.
One of the primary components of the system of the present invention is a GUI that allows the user to monitor and control instruments and to manipulate data views. The software itself provides a numerous visual displays and can produce a variety of reports and graphs from stored data.
When the system is idle (data is not being logged to the database), the following can be altered from the Settings menu in the EA-TOX SYSTEM software:
Equipment settings such as active devices, device name, instrument type, and individual threshold values (
Default thresholds, system units, and communications settings (
Application and database settings (
Map settings such as the map image and text color scheme (
Additionally, a LoopBack Test can be run from the Monitoring menu when the system is idle. The test queries the instruments for monitoring status: Monitoring on—Instrument is on and running; Monitoring off—Instrument is on and not running; or No Response—Instrument is off or communications have failed. Depending on the system settings and the instrument status, the test can determine whether or not EA-TOX SYSTEM queries an instrument during monitoring.
The software can retrieve data from instruments with data logging capabilities and integrate and/or synchronize that data into the database. This feature is especially useful in situations where a large number of instruments are being monitored, resulting in potential data gaps related to communications limitations. It can be accessed through the Maintenance menu only when the system is idle.
During monitoring, EA-TOX SYSTEM queries instruments continuously at user determined intervals between 1 and 30 seconds, logging data to the database at the Control Unit. Query results for each instrument are displayed on the GUI. The software can also continuously perform a variety of statistical calculations, as determined by the user, display the results on the GUI, and log them to the database. EA-TOX SYSTEM also alerts the user to threshold breeches via audio and visual alerts.
EA-TOX SYSTEM offers multiple data viewing options. In the Device View, the GUI displays monitoring status; the time of the most recent query; all instruments to be monitored; an Alert Log listing any readings over warning levels or thresholds; and the Remote Panel Display (
When the EA-TOX SYSTEM is monitoring, the Device View shows the device name, current reading, and other information (depending on the instrument and monitoring requirements) for each instrument (
The Alert Log displays recent alert messages, as defined by the user. Each message includes the name of the affected device, the reading at the time of the alert, the date and time of the alert, and information about the type of alert. The alerts are saved to the database as they occur and can be reviewed at any time. In addition, the user may opt to save messages in the Alert Log and clear them from the screen.
The Remote Panel Display mimics the physical layout of the instruments and allows the user to remotely manipulate individual instruments. The degree of control the Remote Panel Display allows is limited only by the restrictions of a given instrument type to receive commands remotely. In accordance with one aspect of the present invention, where limited communication resources are available, instruments can only be accessed when EA-TOX SYSTEM is idle. However, in accordance with a further aspect of the present invention, a second communication loop is added with the instruments so that they can be accessed and controlled when the main system is alive.
A variety of reports and graphs can be produced directly from EA-TOX SYSTEM. The Summary Report lists the device name; daily average; monitoring start and stop time; and other user-defined information for a specific day (
In accordance with a further aspect of the present invention, remote access to the system can be gained through an intranet, the Internet, or other remote access protocols. In addition, handheld units with wireless communications such as PDAs can also be used to monitor instruments. Users with permission to remotely access the system of the present invention can monitor and control equipment on a real-time basis from off-site. Users with access to the database are able to view up-to-date logged data. The type and level of access permitted can range from read/view-only to full access/control and is determined by settings on the Control Unit.
When the system of the present invention is operating un-staffed or when specific users need to be apprised of certain events, Annunciators can be utilized to relay alerts and/or information. Annunciator messages can be delivered via pager, phone, email, or other forms of electronic communication and can contain a simple message or instantaneous readings and statistics from a given time, as determined by the user.
There are many benefits of the system of the present invention. The benefits include, but are not limited to, the centralized, standardized control of an entire environmental and air monitoring system; a high degree of flexibility; and diverse notification and access options. The system and methods in accordance with the various aspects of the present invention also provide the ability to view relevant monitoring data in different views. It also provides multiple levels of alarms.
One of the central features of the system of the present invention is the ability for the user to access and control virtually all aspects of the air monitoring instruments and data from the Control Unit. Another key benefit of the system is its high degree of flexibility. It allows a user to monitor a high number of and wide variety of instruments simultaneously. The instrument manufacturer and model are irrelevant, as long as the instrument has serial communications capabilities and can receive commands remotely. In addition, the system's compatibly with virtually any serial communication system allows the user to retain existing systems or implement a system that best suits the situation.
In accordance with one aspect of the present invention the communication between instruments 10 to 13 and the base station 14 is provided via a wireless link. The communication is preferably two-way between the instruments 10 to 13 and the base station 14. Accordingly, each of the instruments 10 to 13 and the base station 14 has a two-way radio device in it. Of course, communications between instruments 10 to 13 and the base station 14 can also be provided via wired connection or via any other means.
In accordance with another aspect of the present invention a weather instrument 16 can also be provided. The weather instrument measures pertinent weather data, such as wind speed and direction. The weather instrument 16 is in communication with the base station 14. Again, the communication between the weather instrument 16 and the base station 14 can be provided wirelessly, via a wire connection or by any other communication means.
Instruments 10 to 13 are preferably located around a perimeter of a site. Additional instruments can be provided in the interior of the site or at any location or area designated for monitoring, if desired. The site can be a remediation site where environmental clean up is occurring and is important to measure the quality of the air as toxic materials are removed from the site. This site can also be any other construction site, demolition site, remediation site or emergency site. Sufficient instruments are utilized so as to be able to provide the good coverage around the perimeter of the site as well as at interior points inside the site.
A control unit 18 is in communication with base station 14. The control unit 18 is generally provided in a structure located on the site being monitored, although the control unit 18 can be provided anywhere. The communications between the base station 14 and the control unit 18 is typically provided via wired connection. The communications can also be provided by a wireless interface, such as a radio interface.
The control unit 18 includes computers and databases. The control unit 18 receives data from the instruments 10 to 13 and 16 and causes that information be stored in a database and displayed at the control unit 18. The control unit 18 can also provide control of the instruments 10 to 13.
An Internet connection interface 20 is provided to the control unit 18. Thus, various devices such as an alarm 22, another CRT 24 or a PDA 26 can be provided. Data from the instruments 10 to 13 and 16 that are stored at the control unit 18 can be displayed on the devices 22, 24 and 26 via the Internet connection 20. The information displayed on the devices 22, 24 and 26 can be real time data as it is obtained from the instruments 10 to 13 or it can be historical data obtained from the database of the control unit 18. The displayed information can also be a combination of both real time and historical data.
A remote annunciator 30 can also be provided and be placed in communication with the control unit 18. The remote annunciator 30 can be a phone, a radio, and/or a PDA. Again, the information displayed at the remote annunciator 30 can be real time data as the control unit 18 obtains such data from the instruments 10 to 13 and 16, or it can be historical data from the database at the control unit 18. Alarms, as they occur from the instruments 10 to 13 can also be provided at the remote annunciator 30.
In accordance with another aspect of the present invention, clicking on a check box when the associated device is disabled will activate the device. Similarly, clicking on a check box when the associated device is enabled will disable the device.
Various thresholds associated with each active device are also illustrated under the four columns entitled Thresholds. Two types of thresholds are provided. A current threshold which is an instantaneous threshold, is provided. An average threshold, which is a time average rolling average (typically for 15 minutes) is also provided. Two thresholds are provided for the current threshold and the average threshold. The first threshold is a warning threshold and the second threshold is a not-to-exceed threshold. Thus, for example, for device 1, if a measurement of 200 is obtained as an instantaneous reading, a warning alarm is generated by the control unit 18. The control unit 18 sends an alarm according to a variety of programming methods. If the instantaneous measure, however, exceeds 380, then a second distinct alarm is enabled by the control unit 18. In this case, a second set of action items will be taken as a more serious threat has been detected. Similarly, two alarms are provided for the moving average thresholds as well. The alarm 22, CRT 24, PDA 26 or the other remote annunciators 30 can sound an alarm when any of the thresholds are crossed.
The individual instruments 10 to 13 can also generate alarms. Those alarms could be transmitted to the control unit 15 and used to generate system alarms to the CRT 24, PDA 16 or other remote annunciator 30. The alarms from the individual instruments 10 to 13 can be used independently from the alarms generated from the control unit 15 or they can be used in conjunction with the alarms generated by the control unit 15.
The setting information on this window can be saved to the database of the control unit 18 by pressing the Save button. Default settings can be restored by selecting the Restart Default Settings command button.

The number of data bits is selected in text box 48. The use of parity is selected in text box 49. The number of stop bits is selected in text box 50. The read timeouts and the write timeouts are selected in text boxes 51 and 52, respectively. These settings determine the amount of time a control unit 15 will wait for a signal before it decides to move to the next instrument. Any necessary communications protocols can be controlled by providing the appropriate interface.
The default control settings for a device can be reset to the default settings by selecting the Restore Default Settings command button.
An inter-device delay can be set in box 55. This is the time delay between the responses by individual instruments 10 to 13. Check box 56 can be checked to implement a start up test. If the check box 56 is checked, then a loopback test is conducted on the instruments 10 to 13 on system start up. The loopback test queries all instruments to establish the status of the communication link to each device and their ability to respond to the base station. The loop back test is done at system start up automatically or it can also be done manually.
The font size of the display of the map and device windows can be selected in box 57. The type of alerts the system issues can be set with check box 58. If check box 58 is selected, then the system issues audible alerts when a threshold or a series of thresholds are exceeded. The type of the audible alert can be selected in a box 59.
The parameters to connect to the database in the control unit 18 are set in boxes 60 to 63. The mode (normal or diagnostic) is set in box 64. Again, all default settings for the operating parameters can be restored by clicking on the command button Restore Default Settings.
The control unit stores various maps that can be displayed with the area being monitored. By way of example only, all standard image/graphical formats (jpg, gif, bit maps, pdf) can be used as the map in the system.
Additionally, multiple maps can be used. Thus, maps of various areas being monitored can be displayed and selected by a user for viewing in accordance with the present invention.
A status for each device is displayed. Thus, for example, the status of Device 1 is “Monitoring On” indicating that the device is monitoring its surrounding environment. Similarly, Device 5, Device 8, Device 9, Device 10, Device 20, Device 21, Device 22, Device 23, and Device 24 all have a status of “Monitoring On” which indicates that they are actively monitoring the environment.
Device 4 has a “No Response” status, indicating that Device 4 is not reporting to the base station 14. Similarly, Device 6, Device 7, and Device 11 have a No Response status indicating that they are not reporting to the base station 14. If desired, a person can be dispatched to investigate the operational status of the devices. In accordance with another aspect of the present invention, an alarm can be issued by the control unit 18 to indicate which devices are not operational or not reporting back to the base station 14. The alarm can be played on the alarm 22 or the remote annunciator 30.
For those devices that are reporting back to the base station (having a “Monitoring On” status), Available Instrument Memory Capacity (M) and Battery Status (B) are also indicated. The instrument memory is the memory available to device specific data log which can be synched to control unit data log.
Thus, it is possible to synch the data in the instruments 10 to 13 to the data in the control unit 15.
