Abstract
A system and method to flexibly control intervals between trains in which there are base stations at predetermined intervals along a train rail. Each base station has a radar which detects data of distance between the base station and trains moving on the train rail, a traveling command calculator which calculates a traveling command based on the date of distance, and a traveling command providing device which provides the traveling command calculated by the traveling command calculator to the trains.
Claims21
A train control system for controlling trains of at least one vehicle that travel along a train rail comprising:
- a plurality of base stations at predetermined intervals along the train rail, each base station comprising:
- a radar for detecting data of distance between the base station and trains moving on the train rail within a predetermined distance of the base station;
- a traveling command calculator for calculating a traveling command based on the data of distance detected by said radar and the radar of another base station, said traveling command calculator comprising
- a signal transmitter-receiver which transmits and receives distance data detected between each base station and one or more trains;
- a train interval calculator which calculates distances between the trains from the distance data between a base station and the one or more trains as detected by the radar of the base station, or by the distance data detected between another base station and the one or more trains received by the signal transmitter-receiver of the base station;
- and
- a speed command calculator which calculates from the distances calculated by said train internal calculator a speed command to be transmitted as a traveling command for one or more trains to which the speed command must be sent;
- and
- a traveling command providing means for providing to the trains the traveling command calculated by said traveling command calculator.
A method for controlling trains of one or more vehicles by a plurality of base stations spaced at predetermined intervals along a train rail along which the trains travel comprising the steps of:
- detecting data of distance between each base station and one or more trains moving on the train rail by a radar at each base station;
- transmitting the distance data between each base station and the one or more trains detected by the radar at the base station from one base station to another base station;
- calculating the distances between the trains by the distance data received from another base station and the distance data detected by the one base station;
- calculating in response to the calculated distances a speed command to be transmitted as a traveling command for one or more trains to which the speed command must be sent;
- and
- calculating a traveling command based on the distance data between one or more trains and each base station detected by the radar of the respective base station.
