Distributed train running control system based on communication

Abstract

The invention discloses a distributed train running control system based on communication. In combination with existing computer control technology and digit communication technology that are developing in high speed, increasing demand like high density and long transportation is satisfied. The technical scheme is that the system comprises a train automatic supervise system (ATS), a trackside terminal controller (TDC), a vehicle ATC apparatus and a data communication system. The running control system can realize train path calculation and train running path dangerous obstacle protection.

Description

technical field [0001] The invention relates to a train operation control system, in particular to a distributed communication train operation control system. Background technique [0002] With the development of my country's urban rail transit signal control technology, CBTC signal system (Communication Based Train Control) has become a widely used signal control technology. The CBTC signal system is widely used in the train safety operation protection signal control system of urban rail transit. The CBTC signal system is based on the large-capacity, continuous train-to-ground two-way wireless communication technology and the principle of mobile block control, and based on the train positioning and control technology, it realizes the control system of train speed control and safety protection. The block diagram of the CBTC signaling system is as follows: figure 1 shown. [0003] The trackside CBTC equipment obtains the status information of the obstacles in front, includ...

AI Technical Summary

Problems solved by technology

[0008] The problem of improving the performance of the CBTC system: in the current CBTC system architecture, the computing processing and communication capabilities of the trackside CBTC equipment will restrict the performance of the entire CBTC system

[0009] Simplify the design of CBTC technology: Traditional interlocking is a mature device whose functions are relatively independent and fully verified on site. The later development of CBTC equipment and functions is based on the existing interlocking functions as much as possible.

[0010] The problem of streamlining the system architecture: the traditional CBTC system architecture is composed of interlocking, ATS, trackside CBTC equipment, vehicle-mounted CBTC equipment and communication systems. The interfaces between the systems are intricate and complex, which increases the complexity of the system

Any problem with any part of the system will cause the system to fail to operate normally, affecting the overall operational efficiency and passenger comfort.

At the same time, each manufacturer uses a dedicated communication protocol or physical transmission channel between the components in the system, and recommends a complete system to users on the grounds of ensuring system security, which brings a huge economic burden to users.
