DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train control device, and more particularly to a train control device having a small facility cost on the ground.

[0002]

2. Description of the Related Art Conventionally, as this type of train control device,
A stop pattern corresponding to the deceleration when braking is applied to the own train running at a predetermined speed is generated, and the lower end of the stop pattern is matched with a stop target point to stop the own train. It is configured to stop along the pattern.

[0003] To explain further with reference to Fig. 3, a track section (rail) R is divided into a predetermined length and a block section (three block sections in the illustrated example) 1T to 3T on the train traveling direction side. (hereinafter, referred to as the starting end side) together with the transmitter a ₁ in are respectively provided, in the example of the plurality of transmitters (not keeping a predetermined interval in the middle of each block section 1T~3T 3
Transmitters) A _{2 to} A ₄ are provided. Each of the transmitters A _{1 to} A ₄ includes an antenna (a ground antenna), and is configured to transmit travelable distance data from the position of each transmitter to the upper side of the vehicle via the antenna.

[0004] The upper side of the train, that is, the own train a and the preceding train b have an antenna (vehicle upper part) 1 at the lower part of the head of the train, and can run from the above-mentioned transmitters A _{1 to} A _4. It is configured so that distance data can be input. A signal processor 2 formed of a microcomputer is mounted on each of the trains a and b. The brake is activated when the train is running at a predetermined speed, and the distance from when the train stops at this time is determined. The obtained stop characteristic diagram is stored. Therefore, when the stop target point which is the end point of the travelable distance is set, a stop pattern having the stop target point as a stop point can be generated.

Therefore, now, as shown in FIG.
When the own train a is running in the block section 1T and the preceding train b is running in the block section 2T, the own train a does not enter the block section 2T, so the boundary between the block section 1T and the block section 2T. The end point of the block section 1T or the start point of the block section 2T is the stop target point of the own train a. For this reason, the transmitter A ₁ transmits the signal from the transmitter A _{1 in a} section 2T.
Travelable distance L to the start end (end of block section 1T)
1 is transmitted to the own train a. Then, as shown in FIG. 4, the signal processor 2 of the own train a generates a stop pattern with the end of the received travelable distance L1 as the stop target point, and the own train a is operated.

By the way, if the preceding train b advances from the block section 2T and enters the preceding block section 3T (see the dotted line in FIG. 3), the own train a terminates the block 2T at the stop target point (block section 3T). it is possible to start end) and the travel distance data based on the travel distance L ₂ is transmitted from the transmitter a _2. For this reason, the signal processor 2 of the own train a can generate a new stop pattern based on the new travelable distance data and operate the own train a. In other words, the own train a can be operated by switching from the present announcement one step higher than the present announcement, for example, from the stop announcement to the caution announcement, because the preceding train b has entered the blockage section ahead.

The other transmitters A ₃ and A ₄ are also connected to the preceding train b.
Is transmitted, and is used to generate a stop pattern of the own train a in the same manner as in the cases of A ₁ and A ₂ described above. The traveling distance data transmitted from each of the transmitters A _{1 to} A ₄ may not be determined based on the condition of the forward section where the preceding train b is located, but may be determined based on the condition of the leading line such as a drop-in line.

[0008]

However, in the above-mentioned conventional apparatus, a plurality of transmitters are provided in each block section to transmit travelable distance data determined according to track conditions to the upper side of the vehicle. There was a disadvantage that the cost was high.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a train control apparatus which can be implemented at a low cost by reducing the number of transmitters.
