DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train control system for transmitting and receiving train control data between the ground and a vehicle.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a train is detected for each closed section, and based on the position of the preceding train, the permissible speed (ATC ground pattern, ATC signal ), And when the following train enters the front block section, the A transmitted to the block section
The TC signal is received as the ATC speed indication and compared with the running speed calculated from the onboard speed generator, and the running speed is determined to be ATC speed.
If the speed is exceeded, a brake command is issued to perform brake control.

In the above-mentioned automatic train control system, when a train enters a closed section, it is necessary to reduce the speed to an allowable speed within the closed section, so that the ATC ground pattern is adjusted according to the train having the worst braking performance. I have decided. Therefore, there is a waste that the length of the closed section becomes too long.

In recent years, as shown in FIG. 4, continuous brake pattern data in consideration of the vehicle performance of a train is created from distance information between a preceding train and a succeeding train, and this data is transmitted from a digital transmission path to a vehicle. The train is sent to the upper side, and on the vehicle, a train running pattern is created based on this to perform deceleration control.

However, the above-mentioned prior art has the following problems.

(A) Although the position of the preceding train is primarily detected by the ground side, it is not known on the ground side whether the train running pattern created on the vehicle is appropriate.

(B) In general, the driver performs the acceleration / deceleration control of the train if the speed is equal to or less than the allowable speed. For this reason, the speed indication indicated to the driver is determined by the brake pattern determined on the ground side. It is unknown whether it is consistent with.

The present invention has been made under such circumstances, and has as its object to provide a highly reliable train control system capable of constantly checking train control data created on a car on the ground side. It is assumed that.

Based on this, the ground brake pattern data for braking this train is created.

The ground brake pattern data is transmitted to the main train via the ground brake pattern transmission unit 27 and stored in the ground brake pattern storage unit 28.

An on-vehicle running pattern / target speed receiving unit 29 receives a train running pattern and a target running speed created on the train, and receives the on-vehicle running pattern and target speed storage unit 30.
Send to A comparison unit 31 compares and checks the data stored in the on-vehicle running pattern and the target speed storage unit 30 with the data stored in the ground brake pattern storage unit 28. Data from the comparison unit 31 is transmitted to the main train via the ground brake command transmission unit 32.

In FIG. 2, reference numeral 1 denotes a speed generator coupled to the axle of the main train, and generates a voltage proportional to the speed of the main train. Reference numeral 4 denotes a position information creating unit that creates position information of the train based on the voltage of the speed generator 1. Reference numeral 5 denotes a speed information creating unit that creates speed information of the train based on the voltage of the speed generator 1.
