High-speed railway train control system train control method and system

Abstract

The invention discloses a train control method and system for a high-speed railway train control system, and the technical key points are as follows: detecting whether other trains exist in a front preset distance, and if not, adopting a first train control mode; if yes, a second vehicle control mode is adopted; in the second vehicle control mode, the emergency braking distance of the front vehicle is estimated according to the position of the front vehicle, the length of the newest clearing block partition of the front vehicle and the occupied time received from the ground RBC; according to the service braking curve and the emergency braking curve of the current running train in the second train control mode, the running state of the current running train is controlled; and meanwhile, according to the emergency braking distance of the front train and the real-time position and speed of the current running train, the running state of the current running train is adjusted in real time. According to the invention, the absolute safety of the train is ensured by meeting the requirement of hard wall collision from the angle of emergency braking; from the perspective of service braking, soft wall collision is achieved, the train running efficiency is guaranteed, and the high-speed rail operation efficiency and the line trafficability are improved.

Description

technical field [0001] The invention relates to the technical field of rail traffic and intelligent transportation, in particular to a vehicle control method and system of a high-speed railway train control system. Background technique [0002] With the increasing passenger flow of high-speed railways, the capacity of some busy sections of high-speed railways is close to saturation, and the theoretically calculated capacity utilization rate has exceeded 100%. The passing capacity of high-speed rail mainly depends on the tracking interval and the mode of transportation organization (train speed class, stop mode, etc.). The transportation organization model needs to meet the passenger demand as much as possible, and the optimization space is limited; the train tracking interval time is the final manifestation of the comprehensive level of lines, vehicles, signals, operations, etc., and the passing capacity of the line can be significantly improved by compressing the train trac...

AI Technical Summary

Problems solved by technology

However, the vehicle control mode of hitting a soft wall can only be realized under the assumption that the vehicle in front will not derail or collide. In actual operation, it is impossible to guarantee that the train will never derail. There are relatively large casualties. At this time, if the rear train collides with the derailed front train, it will inevitably cause more serious and unacceptable consequences. Therefore, the absolute safety of the rear car cannot be guaranteed under this car control mode. The concept of operational security is contradictory and has not been realized in practice
