Description

  The present invention relates to a fixed position stop control device that stops a train at a fixed position, and more particularly to simplification of a ground device that performs distance correction to stop a train at a fixed position.

  The train control system uses an automatic train control device (hereinafter referred to as an ATC device) and an automatic train operation control device (hereinafter referred to as an ATO device) to automate driving operations and improve safety. In the driving method using the ATC device, the ATC signal sent from the ATC ground device to the ATC loop provided for each block section along the track circuit or track is received by the power receiver or ATC antenna provided in the head vehicle of the train. The train speed is automatically controlled below the speed limit based on the received ATC signal. Also, in a new transportation system using rubber tire vehicles, a check-in / check-out method is used because a track circuit due to an axle short circuit like a general railway cannot be used for train detection. The check-in / check-out method transmits signals with different frequencies from the front and the rear of the train, and receives this signal with the ATC / TD loop provided for each block section along the ground track. Detecting the presence or absence of trains in In recent years, a digital ATC device capable of transmitting a large amount of information has been adopted as the ATC device. By adopting this digital ATC device, it is possible to achieve multiple display and multiple functions, and it is possible to realize functions other than speed control.

  In addition, by adopting a digital ATO device that automatically controls the operation of trains such as constant speed control, fixed position stop, and door opening / closing, multi-functionality is possible, and functions other than speed control are realized. It is possible. In order to stop the train at a fixed position with this ATO device, as shown in FIG. 5, a plurality of point information detecting ground elements 21a to 21c are installed at a fixed point in front of the station stop position. When the vehicle upper 23 mounted on the train 1b passes over the point detecting ground element 21a, the ATO transmitter / receiver 22 receives a signal from the point information detecting ground element 21a and the ATC / ATO control device 2 receives the signal. A fixed position stop control pattern (TASC pattern) is generated. Thereafter, the ATC / ATO control device 2 performs optimum brake control so that the train speed matches the TASC pattern, and when the signals from the point information detecting ground elements 21b and 21c installed near the stop position are received, the TASC pattern The train stop position is accurately controlled by sequentially correcting the above.

As shown in Patent Document 1, a transponder is used for the vehicle upper element 23 and the ground element 21. As shown in the configuration diagram of FIG. 6, the vehicle upper arm 13 includes an information transmission coil 24 and a power wave transmission coil 25 including two sets of loop coils. The point information detecting ground element 21 has a power wave receiving coil 26 and a transmitting coil 27, receives the power wave from the vehicle upper element 23 by the power wave receiving coil 26, and smoothes the received power wave by the power supply unit 28. -It is set as the unpowered ground unit which rectifies and uses as the electric power of the message | telegram transmission part 29. FIG. The ATO transmitter / receiver 22 mounted on the train 1 always transmits a power wave to the ground via the vehicle upper part 23. When electric power is induced in the point information detecting ground element 21 when the vehicle upper piece 23 passes over the point information detecting ground element 21, the message transmitting unit 29 receives the fixed information set in the message setting unit 30. The data is transmitted from the transmission coil 27 to the vehicle upper arm 23.

  A process for stopping the train 1 at the stop target position of the station with this distance correction device will be described with reference to the fixed position stop control pattern diagram of FIG.

  The information transmitter 3 mounted on the train 1 constantly transmits vehicle information indicating a vehicle number and the like to the ground via the transmission coil 5. The train 1 enters the track circuit 3T to which the ATC / TD ground device 7c installed at a fixed position in front of the traveling direction of the train 1 from the stop target position of the station is connected, and the ATC / TD ground device 7c. When detecting that the train 1 has entered the track circuit 3T, the ATC / TD ground device 7c transmits an ATC signal including a fixed position stop control (TASC) pattern signal to the track circuit 3T together with the track circuit ID. The ATC receiver 4 of the train 1 receives the ATC signal transmitted to the track circuit 3T via the receiving coil 6, and sends the received ATC signal to the ATC / ATO control device 2. The ATC / ATO controller 2 corrects the distance by the sent ATC signal and generates the TASC pattern 13a. Then, appropriate brake control is automatically performed so that the speed of the train 1 traveling at the ATO target speed matches the generated TASC pattern 13a. When the train 1 whose speed is controlled by the TASC pattern 13a enters the track circuit 4T from the track circuit 3T and the ATC / TD ground device 7d detects that the train 1 enters the track circuit 4T, the ATC / TD ground The device 7d transmits the ATC signal including the TASC pattern signal together with the track circuit ID to the track circuit 4T. The ATC receiver 4 of the train 1 receives the ATC signal transmitted to the track circuit 4T and sends the received ATC signal to the ATC / ATO control device 2. The ATC / ATO control device 2 corrects the distance by the sent ATC signal and generates the TASC pattern 13b. Then, the speed of the train 1 traveling by the TASC pattern 13a is corrected so as to match the generated TASC pattern 13b, and the speed control of the train 1 is performed.

  When the ATC / TD ground device 7e detects that the train 1 has entered the track circuit 5T from the track circuit 4T, the ATC / TD ground device 7e transmits an ATC signal including a TASC pattern signal to the track circuit 4T. The ATC receiver 4 of the train 1 receives the ATC signal transmitted to the track circuit 5T and sends the received ATC signal to the ATC / ATO control device 2. The ATC / ATO control device 2 generates a TASC pattern 13c by correcting the distance based on the sent ATC signal, and corrects the speed of the train 1 so as to match the TASC pattern 13c generated.

  The train 1 approaches the vicinity of the stop target position of the station, the transmission coil 5 of the train 1 reaches the information reception coil 8 provided on the ground, and the vehicle information transmitted by the transmission coil 5 of the train 1 is transmitted. When the information is received by the loop coil 11 arranged on the entry side of the information receiving coil 8, the vehicle information receiver 9 sends a signal indicating that the vehicle information is received by the loop coil 11 to the station control device 10. When receiving a signal indicating that the vehicle information has been received by the loop coil 11, the station control device 10 sends the position information of the tip of the loop coil 11 to the ATC / TD ground device 7e. When the position information of the tip of the loop coil 11 is sent, the ATC / TD ground device 7e corrects the TASC pattern signal included in the ATC signal being transmitted. The ATC / ATO control device 2 of the train 1 generates the TASC pattern 13d by the ATC signal sent via the ATC receiver 4, and corrects the speed of the train 1 so as to match the TASC pattern 13d that generated the train 1. Further, when the train 1 travels and the vehicle information transmitted by the transmission coil 5 of the train 1 is received by the loop coil 12 of the information reception coil 8, the vehicle information receiver 9 has received the vehicle information by the loop coil 12. Is sent to the station control device 10. When receiving a signal indicating that the vehicle information has been received by the loop coil 12, the station control device 10 sends the position information of the tip of the loop coil 12 to the ATC / TD ground device 7e. When the position information of the tip of the loop coil 12 is sent, the ATC / TD ground device 7e corrects the TASC pattern signal included in the ATC signal being transmitted. The ATC / ATO control device 2 of the train 1 generates the TASC pattern 13e by the ATC signal sent via the ATC receiver 4, corrects the speed of the train 1 to match the TASC pattern 13e that generated the train 1, and Stop at the stop target position.

Therefore, the train 1 is stopped at the stop target position. Therefore, it is not necessary to provide a plurality of point information detecting ground elements composed of transponders that transmit point information for causing the ground device to stop the train 1 at a fixed position. When the two sets of loop coils 11 and 12 of the information receiving coil 8 provided at the stop target position receive the vehicle information of the train 1, the TASC pattern is corrected by the position information of the tips of the loop coils 11 and 12. Since it did in this way, the stop precision of the train 1 with respect to a stop target position can be improved.
