Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train operation warning device employing a block system for safely operating a train.

[0002]

2. Description of the Related Art In general, a block operation system is employed to ensure the safety of train operation. In this blockage scheme, entry of one train is permitted in a block section provided in advance, and entry of another train is prevented. On the other hand, an ATC (automatic train control device) is employed for train operation. This ATC continuously presents a signal indicating the permissible operating speed of the train on the vehicle according to the conditions of the distance from the preceding train and the route, and automatically reduces the train speed according to the signal. It was done.

The ATC is composed of a ground device and an on-board device. The ground equipment has two functions of detecting the train and transmitting the ATC signal to the train. Based on the train position information obtained by the train detection function and the conditions of the route obtained from the interlocking device, the ATC signal is tracked. Send to circuit. That is, a track circuit for train detection is provided in the block section. Then, in the track circuit where the train does not exist, the transmitted AT
The C signal is received by the ground equipment and detects no train. When the train is on the train, the transmitted ATC signal is received by the train, and the command of the speed limit in the block section from the ground device is known. In this case, the ground device detects that the train is in the block section.

The on-board device has a function of receiving an ATC signal from the ground device and issuing a brake command when the train speed is higher than the train speed. The ATC signal sent from the ground equipment is received by the on-board equipment and displayed on the speedometer. The train speed is compared with the ATC signal, and when the train speed is high, a brake command is issued, and the train speed becomes A
When it becomes lower than the TC signal, a brake machine solution command is issued.

[0005]

However, when the train is operated by such a block method, the speed limit of a certain block section is first displayed on the cab when the vehicle enters the block section. Automatic deceleration and cancellation by the ATC are frequently performed during a high rush hour. When the vehicle enters the next block while accelerating in a block, the ATC brake is often applied immediately. In such a case, riding comfort is poor and energy is wasted.

As a means for solving this problem, a system is used in which two signal frequencies are provided, the ATC is multistaged by a combination thereof, and a signal for notice is assigned. However, there is a limit to the combination in this system. And also AT
There was a problem in terms of cost because a major remodeling was required to review the entire C system.

Embodiments of the present invention will be described below. FIG. 1 is an explanatory diagram of the first embodiment of the present invention.

In FIG. 1A, a trajectory 1 is divided into a plurality of block sections by a boundary 2. A track relay 3 for detecting that the train 8 has entered the block section is provided near the boundary 2, and the detection signal is input to the ground controller 6. An ATC signal wave receiver 4 and an ATC signal wave receiver 5 are provided on the orbits 1 on both sides of the boundary 2. The ATC signal wave receiver 4 receives an ATC signal wave in a block section.
The TC signal wave receiver 5 receives the ATC signal wave in the next block section.

The ground controller 6 sends a signal from the track relay 3 to the boundary 2
And the ATC signal wave receiver 4 and the ATC signal wave receiver 5 receive an ATC signal wave from the ATC signal wave receiver 4 and the ATC signal wave receiver 5. The ATC signal wave includes an ATC code indicating the speed limit of the train 8 in the block section, and the ground controller 6 instructs the radio wave transmitter 7 to transmit information on the speed limit to the radio wave transmitter 7.

The train constituting the train 8 is provided with a radio transmitter 7
A radio wave receiver 9 for receiving a radio wave transmitted from the vehicle and an on-board controller 10 for receiving a radio wave and instructing the display 11 to display a message.

FIG. 1B is a flow chart showing the operation contents of the ground controller 6. When the train 8 enters a block section, the track relay 3 detects that the train 8 has entered the block section. Therefore, the ground controller 10 determines whether or not the track relay 3 has detected that the train 8 has entered the block section (S1), and if it determines that the train 8 has entered the block section, The speed limit of the train in the block section is compared with the speed limit of the train in the inner block section (S2). When the speed limit in the opening section on the inner side of the boundary 2 is lower than the speed limit on the outer side, the radio wave transmitter 7 is instructed to transmit radio waves (S3).

Here, the outer block section means a block section in which the ATC signal wave receiver 4 is installed, and the inner block section means a block section in which the ATC signal wave receiver 5 is installed. It refers to a section. The train speed limit in each block section is determined by the ATC signal wave receiver 4 and the ATC
It is detected by the ATC signal wave received from the signal wave receiver 5. Then, the ground controller 6 compares these speed limits, and when the speed limit of the inner opening section of the boundary 2 is lower than the outer speed limit, the ground controller 6 instructs the radio transmitter 7 to transmit radio waves. I do. This is because the speed of the train 8 decreases when the train 8 enters an inner block section (next block section).

Instructs transmission of radio waves toward. In the train 8, when the radio wave receiver 9 receives the radio wave, the on-board controller 10 instructs the display 11 to display a message of the brake notice.

Here, the train 8 to which the brake notice should be transmitted
In order to prevent the brake notice from being transmitted to the front and rear trains 8 operating on the same track as above, radio transmission is performed by limiting the radio transmission directivity angle and the radio wave reachable range. Further, in order to prevent the train 8 to be transmitted from being transmitted to another train 8 operating on a nearby track, a different transmission frequency is set for each track.

As means for informing the driver that the speed limit by the ATC will be reduced, a radio wave receiver 9, a vehicle controller 10, and a display 11, which are separate from the ATC on-board device, are mounted on the vehicle. I am trying to install it.

The on-board controller 10 determines whether the radio wave receiver 9 installed on the vehicle 8 has received radio waves from the radio wave transmitter 7 on the ground (S13). When a radio wave is being received, the on-board controller 10 determines the speed limit of the block section ahead by the frequency of the received radio wave and compares it with the speed limit of the currently operating block section input from the in-vehicle signal 12. (S14).

As a result of the comparison, if the speed limit of the preceding block section is lower than the current speed limit of the block section, the display 11 is instructed to display a brake notice message (S15). FIG. 2D shows a display example of the advance notice display on the display device 11.
