DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stationary stop device for stopping a train at a target point, and more particularly to an improvement in stop position accuracy.

[0002]

2. Description of the Related Art In recent years, an automatic train operation method (hereinafter referred to as ATO) for automatically controlling operation such as speed control and stop of a train.
Has been adopted. The ATO operation is a method in which the train speed, the position, the operation time, the preceding train and the track condition are always known, and the train speed is controlled while comparing with the reference operation diagram to operate the train and stop at a predetermined position.

As a method for automatically stopping the train at a fixed position, as shown in FIG. 5, a powered ATO grounding member P4 is provided at the stop point of the train 1 in the station home 2, and the fixed position is stopped. Non-powered ground terminals P1, P2, and P3 are installed at the fixed position stop control start point and the distance correction point of the control section, and when the train 1 receives a signal indicating the fixed position stop control start point from the non-powered ground child P1, the fixed position. The fixed position stop control is performed by the stop pattern. Whenever the signals indicating the distance correction points are received by the non-powered ground terminals P2 and P3, the remaining distance from the stop target point is corrected and the fixed position stop is performed. I have. The ATO on-board device provided in the train 1 determines that the train 1 has stopped at a fixed position when a point signal from the ATO ground child P4 is input when the train 1 stops. When the train 1 stops between the non-powered ground child P3 and the ATO ground child P4 before the ATO ground child P4, the ATO
The on-board equipment is used for the train 1 in the inching area where fine movement adjustment is performed.
Is judged to have stopped, the train 1 is automatically advanced at a very low speed,
When the point signal from the ATO ground child P4 is received, the operation is stopped. Also, train 1 does not stop at the stop point of home 2
When the balun occurs, the driver has retreated the train 1.

[0004]

As described above, the conventional fixed position stop device uses a rubber tire vehicle, for example, because the driver retreats the train when the train overruns without stopping at the stop point. When a train is operated unmanned by a new transportation system or the like, it is necessary for the driver to get on and retreat every time the train overruns, and it takes time to correct the stop position of the train. The operation was troublesome.

The present invention has been made in order to improve such a disadvantage, and even when a train overruns from a stop position, the stop position can be automatically corrected to stop at a fixed position. It is intended to obtain a device.

[0006]

A fixed position stopping device according to the present invention comprises a position detection loop and an ATO data as ground devices.
A position detection loop is provided at a fixed position stop point of the train and is adjacent to the front of the ATO ground child in the direction of travel of the ATO ground child that performs mutual communication with the vehicle upper child of the train. The ATO data transmission / reception device transmits / receives information to / from the train via the ATO data transmission loop, and the operation management device transmits a stop signal as an ATC signal.
When a train is detected by the position detection loop after detecting the train with the ATO ground child, it is determined to be the train stop position over and the train is stopped.
Outputs a stop position over alarm and outputs a train stop position over alarm.
When the confirmed operation commander on the ground sets the station code and the track and sets the inching behind the train, the inching command and the inching speed command are sent to the ATO data transmission / reception device, and the inching command behind the train. When the train is detected to have stopped at the fixed position stop point after sending out the train, the inching command at the rear of the train is released, and the ATO on-board device provided in the train transmits the train via the ATO data transmission loop. When the backward inching command is sent, the running direction is set to the reverse side, and the train is driven backward by the sent train backward inching speed command, and the train is stopped when the ATO antenna is detected by the station ATO antenna. It is characterized by.

When the train enters the fixed-position stop control section and receives a signal indicating the fixed-position stop control start point from the non-powered ground child P1, the ATO on-board device performs fixed-position stop control using the fixed-position stop pattern. Whenever the signals indicating the distance correction points are received by the non-powered ground terminals P2 and P3, the remaining distance from the stop target point is corrected to perform the fixed position stop. The ATO on-board device determines that the train has stopped at a fixed position when a point signal from the ATO ground child P4 is input when the train stops. Also, when the train stops between the non-powered grounding child P3 and the ATO grounding child P4 in front of the ATO grounding child P4, the ATO on-board device determines that the train has stopped in the inching area where the inching fine adjustment is performed,
The train automatically advances at a very low speed, and stops when a point signal from the ATO ground child P4 is received.

When the stop signal is transmitted as an ATC signal, the operation control device of the central facility detects a train with an ATO ground vehicle and then detects a train with a position detection loop, and then stops the train at a stop position. When the operation commander who determines the train stop position over and sets the station code to set the train rear inching, the ATO data transmission / reception device sends the train rear inching command and the train rear inching. Send out the speed command. The train back inching command and the train back inching speed command sent to the ATO data transmission / reception device are sent to the ATO data transmission loop via the ATO data transceiver provided in the signal equipment room of the station equipment. Can be The ATO on-board device provided on the train sets the traveling direction to the reverse side when the train rear inching command is sent via the ATO data transmission loop, and sets the train in accordance with the sent train rear inching speed command. The train is driven at a very slow speed backward, and the train is stopped when the ATO antenna A4 detects the ATO ground child P4. The operation management device cancels the train rear inching command when detecting that the train has stopped at the fixed position stop point after transmitting the train rear inching command.

In this way, when the train advances to the stop position without stopping at the stop position and reaches the stop position over, the rear inching of the train can be easily performed by the command of the operation commander in the central facility. In addition, the driver does not need to get on and retreat every time the train goes over, and the time for correcting the stop position of the train is greatly reduced.
