Train operation control system

Abstract

The embodiment of the invention provides a train operation control system. The system comprises that a train operation plan is generated, issued and adjusted by a train automatic control system; high-precision train autonomous positioning is realized by a vehicle-mounted controller through correction of a train autonomous positioning system and a trackside transponder; a trackside controller receives commands which are transmitted by the vehicle-mounted controller and used for operating trackside equipment and controls the corresponding trackside equipment to actuate and lock to the corresponding position according to the command requirements; and a data communication subsystem performs data communication with each set of ground equipment via a redundant backbone network and realizes wireless transmitting and receiving of trackside controller information and vehicle-mounted controller information via a wireless communication antenna. CI and ground ATP equipment are reduced and WCU equipment is increased, and mutual resource coordination is performed via a mode of direct communication between adjacent trains and between the trains and the WCU so that system cost is reduced and train tracking efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to a train operation control system. Background technique [0002] With the development of my country's national economy and the acceleration of urbanization, urban traffic congestion and traffic connection problems between large, medium and small cities and small towns are becoming more and more serious. As an important means of relieving traffic pressure, the pace of development of rail transit is accelerating. , the demand for urban rail transit and intercity railway construction is becoming stronger and stronger. [0003] As the "brain and nerve center" of rail transit, the pressure on the development of train operation control technology is increasing. At present, most of the urban rail transit lines under construction in my country choose to use the most advanced CBTC (Communication Based Train Control System, based on wireless communication train automatic control system...

AI Technical Summary

Problems solved by technology

[0004] The CBTC system stipulated in the current standard is composed of subsystems such as ATS (Automatic Train Supervision, automatic train supervision system), computer interlocking, automatic train protection, automatic train operation, and data communication. There are complex interface connections between the subsystems, and the same function There are too many devices involved, the system structure is complicated, and the software design difficulties or software errors caused by the complexity of the system are becoming more and more prominent;

[0005] Since the development of each subsystem is not synchronized, in order to be compatible with the processing methods of the existing system and realize the degraded operation when some equipment fails, the CBTC system retains some non-essential equipment in the mobile block tracking solution, resulting in the cost of the whole life cycle of the system High, especially for intercity railways with long lines and large distance between stations, the current construction and operation costs are unacceptable;
