BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 shows the entire configuration of an automatic train exchange control apparatus according to an embodiment of the present invention, in which the same or corresponding parts as those of the conventional apparatus are denoted by the same reference numerals. On the train, an on-board radio station 10 and an on-board antenna 11 are provided. The ATC track circuit A is provided only at the main line side end and the terminal side end of the depot, which are the start and end points of the train replacement control, on the rails in the depot.
And an ATC track circuit B (hereinafter simply referred to as track circuit A and track circuit B). The track circuit B is provided at the end of the track circuit A, and the radio ground station 12 and the ground antenna 13 are installed. An Rs signal or a Re signal indicating the start or end of the exchange control is sent to the track circuit A, and an RP signal indicating the overrun protection is caused to flow to the track circuit B. Two track circuits B provided at both ends are used. A blockage is formed to prevent collisions between trains in that section. Also, as shown in FIG. 2, there is a possibility that radio interference may occur due to the presence of a building in a normal depot, so two terrestrial antennas 13 (13a, 13b) are installed and their communication areas are set in advance. Keep it. Further, the train does not cross communication by switching the ground antenna 13 for wireless communication according to the on-rail position detected by the train.

The basic operation of the train automatic switching control device thus configured will be described with reference to FIG. First, when a train that has traveled from the main line by automatic train control enters the track circuit A provided at the end of the main line side of the vehicle base to enter the vehicle base, when the train starts, as a start-up control, the train Upon receiving the Rs signal indicating the start of the train replacement control from the track circuit A, the train replacement control is started (described later using FIG. 4). Until the train moves and arrives at the end point, the running of the train is controlled while performing wireless communication between the wireless on-vehicle station 10 and the wireless ground station 12 via the ground antenna 13 as waypoint control (FIG. 5 below).
Then, when the train enters the track circuit A and the track circuit B provided at the terminal end of the depot, the train sends a Re signal indicating the end of the train replacement control from the track circuit A as a stop control. Upon receiving the RP signal indicating overrun protection from the track circuit B, the vehicle stops under emergency control. When the train stops, the train replacement control is received from the track circuit and the train replacement control is terminated (described later with reference to FIG. 6).

Next, the start-up control will be described with reference to FIG. When the train enters the track circuit A from the track circuit B provided at the end of the main line side, the train receives the Rs signal, which is the start permission information of the replacement control, from the general control device 9 via the ground ATC device 7. . After confirming that the signal has been received, the operator inputs a start SW from the radio vehicle upper station 10 to the radio ground station 12. This indicates that the train is ready to start the replacement control. The overall control device 9 confirms that the train is on the track circuit A, receives a start SW from the train, and terminates the departure command and the exchange control for the train via the wireless ground station 12. The route information which is the traveling route of the train to the point is transmitted. At this time, the route from the start to the end of the exchange control at the train depot is secured, and other trains are prohibited from entering the section. Thereby, although the train does not reach the predetermined track circuit, and the operator does not receive the Rs signal from the ground, the operator inputs the start SW of the exchange control, or the operator on the train side checks the train, etc. Despite the other work, the train does not run to the end of the depot, and the safety is maintained. The train replacement control device 3 causes the train to run at a speed equal to or less than a predetermined speed limit pattern,
If the train speed exceeds the speed limit,
The TC device 1 operates the brake.

Next, the waypoint control will be described with reference to FIG. When the train passes through the track circuit A at the starting point, the train position is sent to the general control device 9 on the ground by train radio,
The distance and the speed to the stop position are transmitted at a constant cycle.
On the other hand, the general control device 9 on the ground sequentially transmits the route information and the information of the stop point to the train. The exchange control device 3 on the train always calculates the position of the train obtained from the number of rotations of the wheels from the departure point and the remaining travel distance from the stop point transmitted from the ground to the stop point, while controlling the speed limit pattern. When the train runs at the following speed and the train speed exceeds the speed limit, the on-board ATC device 1 operates the brake. The overall control device 9 on the ground monitors the train position and the remaining running distance received from the train, and stops the wireless communication with the train if it determines that the remaining running distance is incorrect. Then, when the wireless communication from the ground is cut off, the on-board ATC device 1 on the train sets the speed limit pattern to 0 km / h and makes the train emergency stop.

Next, the above stop control will be described with reference to FIG. The running control of the train immediately before the train enters the track circuit A provided at the terminal end of the depot is similar to the waypoint control, but based on the calculated remaining running distance, the stopping point is determined. generating a limit speed pattern such that 0 km / h at S _1. When the train enters the track circuit A, a Re signal indicating the end of the replacement control is received from the general control device 9 on the ground via the ATC device 7 on the ground. This Re signal indicates that the train has a track circuit A provided at the end of the main line.
When the route is secured by entering the train, the general control device 9 sets the track circuit A at the end point of the exchange control of the train.
It was sent to. When the train receives the Re signal, the train generates an approach pattern such as a low speed (close to 0 km / h) at the end of the track circuit A, and brakes the train.

When the train enters the track circuit B at a low speed, an RP signal, which is an overrun protection signal of the train, is received from the general control device 9 via the ground ATC device 7. Upon receiving the RP signal, the on-board replacement control device 3 applies emergency braking to the train and stops the train. Then, the reason for the stop and the stop position are transmitted to the ground. Track circuit A at the stop point of the train
And the track circuit B, and by transmitting the Re signal and the RP signal to the train in two stages, it is possible to reliably stop the train at a predetermined position with less equipment. The general control device 9 transmits the control end permission information to the vehicle and receives the control end information from the vehicle to terminate the communication with the train. As described above, the ATC track circuit is installed only at the main line side end and the terminal side end of the depot to control the operation at the start point and the end point of the train exchange, and the traveling operation from the start point to the end point. By controlling trains by using train radio, facility costs and maintenance costs can be reduced while maintaining system reliability. Further, when an abnormality occurs, the train can be emergency stopped by stopping the wireless communication.

Embodiment 2 FIG. Note that, in the first embodiment, the operation at the time of entry from the main line to the depot has been described.
Similar control can be performed. In this case, the ATC track circuit provided at the end of the main line is the end point of the switching control, and the Re signal is caused to flow instead of the Rs signal. Conversely, since the ATC control circuit provided at the terminal end is the starting point of the switching control, the Rs signal is made to flow instead of the Re signal. AT that stopped the train by sending a Re signal when entering
In order to send the Rs signal to the C track circuit for next departure, it is necessary to confirm that the train is on the ATC track circuit (track circuit A and track circuit B). Then, at the time of switching to the Rs signal, the Re signal flows through the ATC track circuit provided at the end of the main line to secure the route of the train, as in the first embodiment. Since the train is running radially instead of in a line, and the train runs on the same line with the piston, the running direction is reversed since the ground antenna is always located in the same direction (left or right side of the train) from the train. Even with the same antenna and radio equipment, communication with the ground becomes possible. Therefore, wireless equipment can be realized with minimum equipment. Furthermore, in the first embodiment, the route and the stop point information and the like are only transmitted by radio,
Since a large amount of high-speed transmission can be performed, the system can be easily expanded, for example, by transmitting image information and the like in front of the course of a train and monitoring it on the ground.

[0023]

Since the present invention is configured as described above, it has the following effects.

The ATC track circuit is installed only at the main line side end and the terminal side end of the depot, and the operation at the start point and the end point of the train exchange is performed based on the signal received through the ATC track circuit.

Further, at the start point of the train replacement control, the train can confirm the start point by receiving the Rs signal from the ATC track circuit at the start point, input the start SW from the train, and check the train on the ground. The train replacement control is permitted after confirming the presence of the train on the ATC track circuit, thereby improving the reliability of the system.

At the end point of the train replacement control, the train receives the Re signal from the ATC track circuit at the end point, confirms the end point, and can control the stop of the train.

At the end point of the train replacement control, a track circuit B for transmitting the RP signal is provided outside the track circuit A for transmitting the Re signal to stop the train in an emergency manner. It can be reliably stopped at a point.

The ATC track circuits provided at the start and end points of the train changeover control can transmit both the Rs signal and the Re signal, so that the same equipment can be used for both train entry and exit. it can.

When the Rs signal is transmitted to one of the ATC track circuits at the start point or the end point of the train change control, the Re signal is simultaneously transmitted to the other ATC track circuit to secure the course of the train. As a result, safety is maintained.

Further, the Rs signal is converted to the Re signal (or Re signal).
Switching from the signal to the Rs signal) interlocks the detection of the presence of the train in the Re signal section and the detection of the presence of the RP signal section in the train, so that the safety of the train is maintained.

In addition, during traveling from the start point to the end point of the exchange control, the train calculates the remaining travel distance from the stop position obtained by the transmission means and the train position held by the train itself to the stop position, and calculates the value. , A safe running of the train can be realized.

If the ground side determines that there is an error in the distance to the stop position calculated on the train during traveling from the start point to the end point of the interchange control, the radio communication is stopped,
If the wireless communication is stopped on the train, the train is emergency stopped, so that the reliability of the system is high.

Further, since the train selects a plurality of radio stations provided according to the terrain or the like in the depot, according to the location of the train, the radio equipment can be simplified without causing radio interference. .
