Train information transmission method, train speed control method, and train control system

摘要

PROBLEM TO BE SOLVED: To provide a train operation control system for causing high-density, high-speed operation of trains with safety and an information transmitting method therefor. SOLUTION: Control room information such as a speed command and a stopping point is fed from a center to each of the blocked areas of a rail 1. The on-vehicle control device 10 of a train 2 receives this information, computes a speed pattern, compares the pattern with the current speed, and outputs a power running/braking command to cause the train 2 to travel according to the speed pattern. When the train passes through an above-ground element 20, the train number and the time and speed of passage of the previous train, and line conditions such as the gradient of that area, all of which are stored in the storage part 23 of the above-ground element 20, are transmitted to the train 2. The on-vehicle control device 10 then expects the current position of time previous train from the previous train information and, if the distance to the previous train is ample and the line conditions permit an increase in speed, issues a command to increase speed within the range in which safety can be secured, thus correcting the speed pattern. The on-vehicle control device 10 also feeds the train number and the time and speed of passage of the train on which it is mounted to the above-ground element 20, which in turn stores these pieces of information in the storage part 23 as the previous train information for the next train.
