  • Patent number: 10086856
    Abstract: A decentralized control of rail vehicles that run in alternating directions on a single-track route, e.g., between two train stations by way of an exclusive right (token). A storage device is arranged at each end of the route, for instance an RFID unit. Only a single exclusive right exists for the route. The exclusive right is either stored in one of the two storage units or carried along by a rail vehicle that is traveling on the route. In the latter case, an additional rail vehicle is effectively prevented from traveling on the route, because none of the storage units can provide the exclusive right, which is being transported between the storage units by the rail vehicle and is occupied by the rail vehicle. The novel concept creates an efficient possibility of decentralized train protection and thus can be implemented significantly more economically than existing centralized train safety approaches.

  • Patent number: 9156476
    Abstract: An open architecture control system is provided that may be used for remote and semi-autonomous operation of commercial off the shelf (COTS) and custom robotic systems, platforms, and vehicles to enable safer neutralization of explosive hazards and other services. In order to effectively deal with rapidly evolving threats and highly variable operational environments, the control system is built using an open architecture and includes a high level of interoperability. The control system interfaces with a large range of robotic systems and vehicles, autonomy software packages, perception systems, and manipulation peripherals to enable prosecution of complex missions effectively. Because the control system is open and does not constrain the end user to a single robotics system, mobile platform, or peripheral hardware and software, the control system may be used to assist with a multitude of missions beyond explosive hazard detection and clearance.

  • Publication number: 20150102176
    Abstract: Disclosed embodiments provide a system and methodologies that enable or improve a train operator's ability to detect when his train will or has switched tracks or routes automatically in response to the train switching tracks or route without input from the train operator. Disclosed embodiments enable automatic determination of a route that the train is currently on and the route the train is supposed to switch to and the ability to predict track/route switches before they occur. Thus, the disclosed embodiments are configured to more effectively provide proper driving instructions through the track/route change, instead of merely reacting to the track/route change.

    Abstract: A remote control system for controlling movement of a train comprises one or more sensors positioned relative to a railroad track for detecting the presence of a lead railcar on the track being pushed by a remotely controllable locomotive. The one or more sensors are spaced a distance from a predetermined stop location of a lead railcar and transmit signals when the lead railcar is detected on the track. A programmable controller positioned off-board or wayside receives signals from the one or more sensors and is in radio communication with an onboard operating system of the locomotive. The controller transmits a signal to the locomotive when the lead railcar is detected by a sensor, and in response to the signal the operating system of the locomotive sets a maximum speed setting for the locomotive to travel on the track toward the stop location.

  • Patent number: 7722134
    Abstract: A method and system for providing true failsafe control of an electronic braking system by a train control system which controls a switch that supplies power to the electronic braking system. When the train control system determines that it is necessary to activate the train's brakes, it controls the switch so as to remove power to the electronic braking system, which results in activation of the train's brakes. In highly preferred embodiments, the switch is of a type that is normally open and that requires the presence of an electrical signal to close the switch to supply power to the electronic braking system. In such embodiments, any loss in power to the train control system will result in a loss of signal to the switch, thereby causing activation of the train's brakes.

  • Patent number: 7433766
    Abstract: A data transmission system for transmitting data from a central station to a track-bound vehicle traveling on a track includes plural track-side transmitting and receiving devices communicating with an on-vehicle transmitting and receiving device. Each of the track-side transmitting and receiving devices is operatively connected to at least two control computers for communication with the central station. In this way, if the cases arises that the control computer of a pertaining track-side transmitting and receiving device crashes, the communication of this track-side transmitting and receiving device with the central station is maintained through intervention of the other one of the control computers.

  • Patent number: 7201350
    Abstract: A signaling safety system includes transmitter-receiver units for ground-train communication by radio in regular safety operation mode, using a base station and an antenna. The position of each train car is communicated from the cars to a ground train controller which detects the presence of a train on-rail. Based on the latter information, information is transmitted from the controller to each of the cars regarding corresponding speed limits. In addition to such radio transmitter-receivers, the signaling safety system also includes additional communication devices, such that, when each of the cars approaches a specific range, car information from each of the cars can be received by the controller, by communication between ground communication devices and an on-train communication device which are installed so as to communicate with each other. Concurrently with the regular safety operation, by the alternative safety system, the presence on-rail of each of the cars is controlled for each new block section.

  • Patent number: 6928342
    Abstract: A remote control unit for controlling a locomotive by transmitting signals to a remote receiver mounted onboard the locomotive is provided. The remote control unit includes an input for receiving a signal indicative of a command selected from a set of available commands. A signal transmitting unit transmits a signal indicative of the selected command repetitively to create a succession of signal transmission events. In a first example, each signal transmission event is spaced in time from a previous signal transmission event by a certain time interval having a duration conditioned at least in part on the basis of the selected command. In a second example, each signal transmission event includes a message portion and a header portion and the message portion of the signal has a length conditioned at least in part on the basis of the selected command. In a third example, each signal transmission event is characterized by a signal level conditioned at least in part on the basis of the selected command.

  • Patent number: 6666411
    Abstract: A vehicle control system and method in which a plurality of beacon tags are disposed along a length of a track for a predetermine number of blocks. The beacon tags each provide information pertaining its location. Each vehicle that passes along the track has a tag reader that solicits information from the beacon tags and a transmitter that transmits the solicited information, as well as vehicle identification information for the transmitting vehicle, to a wayside control unit. The wayside control unit receives the transmitted position information and vehicle identification information and in turn transmits a single broadcast of information pertaining to each of the blocks of the predetermined number of blocks. This signal is received by all of the vehicles, which use only the information about immediately approaching blocks.
