  • Patent number: 5936517
    Abstract: Each train detects its location, velocity, and the time it will spend to pass the next bifurcation, joint, and intersection, respectively, and sends the information periodically to the trains that are or will be behind the train. The controller of each bifurcation, joint, and intersection, respectively, having mechanical movement sends the connection status of the track to the trains about to pass it. Then, receiving a message, a train can determine if it may hit its front train if its front train stops abruptly and if it may pass the bifurcation, the joint, and the intersection, respectively, before the track there has been connected for it. If yes, the train decelerates to stop to avoid possible disasters. So that the distance between every two consecutive trains can be minimized and different kinds of trains may share the same railroad. Hence, some railroads may be saved.

  • Patent number: 5886619
    Abstract: In an operating system for a movable body that runs on a guide rail, a communication method is described that establishes communications between the movable body and an operation control unit for controlling running of the movable body. Power lines on which electric power is transmitted are laid on the guide rail. The movable body is runnable upon reception of the electric power from the power lines. The method includes the steps of (a) generating a communication signal in either the movable body or the operation control unit; (b) superimposing the communication signal on electric power to be transmitted on the power lines; (c) receiving the electric power with the superimposed communication signal at the other of the movable body or the operation control unit; and (d) acquiring the communication signal from the received electric power.

  • Patent number: 5803411
    Abstract: A vehicle initialization system for a control system that includes a vehicle, such as a train that is to be initialized, a vehicle track, a first reader, an onboard computer and a tachometer. The vehicle is adapted to coact with the track. At least two spaced apart position identifiers are positioned along the track. The first reader attaches to the vehicle and is adapted to read information from the position identifiers and relay the information to the onboard computer. The tachometer is also interfaced with the onboard computer, so that as the vehicle passes the position identifiers, the tachometer can be calibrated and the vehicle direction of travel and the vehicle orientation can be determined. The system also includes a vehicle identifier adapted to identify the vehicle characteristics. A second reader is positioned along the track and is adapted to read the vehicle identifier as the vehicle travels along the track. A wayside computer interfaces with the second reader.

  • Patent number: 5651517
    Abstract: A method of serialization including providing a parameter which varies along the length of the train and transmitting a synchronization signal along the length of the train to the local nodes at each car. The parameter is measured at each node with respect to the occurrence of the synchronization signal at the node. Serialization of the cars is then performed as a function of the measured parameters. One method is to provide the parameters by transmitting a serial signal which propagates through the train at a slower rate than the synchronization signal and then measuring the difference in time between the receipt of the synchronization and the serial signal at each node. A second method of implementation is to create a pressure gradient in the brake pipe along the length of the train. The brake pipe pressure or flow rate is read at each node upon receipt of the synchronization signal. As a third alternative, an electric load is provided at each node in parallel to a trainline running through the train.

  • Patent number: 5487516
    Abstract: A train control system includes an equipment for issuing, to a train under control based on a predetermined train schedule, an operational target to be attained in terms of the aimed position, aimed time and aimed speed. Once a target is issued, a possible run region of the train is determined, and another target may be set within the possible run region such that the train is not subjected to the ATC-based speed limitation or the like, thereby minimizing the cause of delay of the train operation.

  • Patent number: 5459663
    Abstract: An apparatus and method for supplying cab signal to a rail vehicle on a section of track composed of sequentially adjacent railway track circuit blocks. Respective receivers of each track circuit block are monitored for the presence of a vehicle within that block. The cab signal apparatus is controlled to transmit a signal to a block when the output from the respective receiver in that block indicates a different condition from the adjacent receiver of an adjacent block. Output voltages from adjacent receivers are compared to enable transmission of a cab signal. Comparison of adjacent receiver outputs is accomplished through use of a diode bridge.

  • Patent number: 5251856
    Abstract: A control circuit which will momentarily apply a pulse of power to the E-Unit solenoid in response to the momentary interruption of power by the transformer or another control signal. The E-Unit rest state is thus with no power applied, eliminating noise and saving power. A seek-to-forward cycling capability is also provided. The overall system has a remote transmitter and a base unit coupled to the train tracks with a receiver. The base unit controls track switching and individual trains through FSK signals transmitted over the track. The base unit also controls a triac switch between the transformer and the track to allow remote control of track power and impose DC offsets on the track power signal.

  • Patent number: 5092544
    Abstract: Highwasy crossing protection equipment which operates warning lights or crossing gates is controlled from the train locomotive which enters into an interchange of messages via a radio link with the controller at the crossing. Communications between the train and the crossing controller is initiated when the locomotive passes a trackside beacon transponder located beyond a safe braking distance from the crossing. The crossing controller transmits a message addressed to the train acknowledging the receipt of the train signal. The interchange of messages can be repeated a plurality of times; each time the minimum time being updated so that traffic flow across the crossing is handled efficiently with minimum interference.

  • Patent number: 3964702
    Abstract: An anti-collision safety control for vehicles travelling on tracks; the control comprises two safety loops per vehicle, linked to two common loops in a central control station. Each vehicle loop comprises control circuits for determining the distance to the next preceding vehicle, for determining a safe stopping distance for the vehicle, and for stopping the vehicle if the distance to the preceding vehicle becomes smaller than the safe stopping distance or if there is a failure of a safety circuit. The distance control circuit comprises a detector for detecting reference points provided along the track, a counter for calculating the distance of a vehicle from a given zero location, and a delay circuit for converting this distance into a position signal timed to a synchronization pulse received by all vehicles. Position signals from all vehicles are transmitted to the central control and back to the vehicles; the distance to an immediately preceding vehicle is determined by comparing the position pulses.
