Train-train communication management method for train operation control

Abstract

The embodiment of the invention provides a train-train communication management method for train operation control. The train-train communication method comprises the steps that after a train is started, the train sends information of the train to a ground train management unit, and the ground train management unit returns information of all trains in the jurisdiction range of the ground train management unit to the train according information inquiry after receiving the information; the front train is recognized, the relevant trains are determined according to the operating path information of the train and the train information provided by the ground train management unit, communication between the ground train management unit and the relevant trains is initiated, the train exchanges position information with the front train, and the specific position of the front train is determined; and the relation between the train and the front rain is recorded in real time through a train-train communication management module. By adoption of the train-train communication management method, direct communication between the following trains is achieved, safety of key train control information is ensured under all travelling scenes, travelling safety and efficiency are ensured, and the purposes of weakening the functions of ground equipment, decreasing the number of the ground equipment or omitting the ground equipment, optimizing the system structure and reducing safety hazards are achieved.

Description

technical field [0001] The invention relates to the field of train management and application information transmission in a train operation control system, in particular to a train-vehicle communication management method for train operation control. Background technique [0002] In the train control system, the on-board equipment has limited processing capacity, completed functions, and intelligence. The train is controlled by the ground equipment, and the on-board equipment is only responsible for overspeed protection. It is a passive train operation safety protection method. [0003] Taking the CTCS-3 train control system widely used in my country's current high-speed railways as an example, the train-ground communication in the system relies on the wireless GSM-R network to realize two-way, large-capacity security information interaction. RBC (Raid Block Center, wireless block center set up on the ground), receives the train position information and other train parameter ...

AI Technical Summary

Problems solved by technology

In the existing train control technology, due to the limitations of related technologies such as train positioning technology, wireless communication technology, and sensor technology, the on-board equipment only establishes communication with the ground equipment in charge of the train, and cannot obtain the specific position and working conditions of the train ahead in real time. Status and other information, simple processing, single source of information and relatively passive

[0009] Moreover, the ground equipment undertakes too many functions, and the increase in the number of equipment leads to an increase in potential safety hazards

For example, the wireless block center in the CTCS-3 train control system, with its powerful data processing function, its information interaction interface with other system modules is becoming more and more complex, and more communication links are likely to affect the reliability of the system
