Scattered object control terminal system for CTCS

Abstract

The invention relates to a scattered object control terminal system for the CTCS (China Train Control System), which is characterized by comprising a control main frame, a driving collection interface, a track circuit interface and an active responder interface. The control main frame receives control commands from a train control center through a signal safety data network, sends coding control information to a track circuit through the track circuit interface and receives the statue information of the track circuit, sends active responder message information to an active responder through the active responder interface and receives equipment status information, drives an external relay through the driving collection interface and obtains track section information through the track circuit interface and the driving collection interface, obtains information through the driving collection interface, and sends the information to the train control center, a computer interlocking device and a temporary speed-limit server through the signal safety data network. The scattered object control terminal system provided by the invention has the advantages of high security, availability and real-time property.

Description

technical field

[0001] The invention belongs to the automatic control technology of train operation, in particular to a target decentralized control terminal system applied to a CTCS train control system. Background technique

[0002] As the task of railway transportation becomes heavier and the speed of trains runs higher and higher, the problem of ensuring transportation safety becomes more and more prominent. Completely relying on manual observation and manual driving of trains can no longer guarantee driving safety. Even if locomotive signals and automatic parking devices are equipped, safety can only be guaranteed under the normal speed of the train, and the safety guarantee of high-speed trains cannot be realized. With the development of information technology, the technology of Chinese Train Control System (CTCS) has also been continuously developed. CTCS is an important part of high-speed railways by controlling the speed of trains and ensuring that trains run accord...
