Application of Microcomputer Modern Communication Technique in Control of Train Spacing (railway signalling)

摘要

This article presents a new type of control system with vehicle spacing control in railvay section-mobile automatic block system.Microcomputer and modern communication techniques such as automatic data acquisition,data processing and automatic data exchange are used to achieve the automatic control of the new system.New system can increase the traffic capacity in large quantities.A mathematical model describing the train spacing control system is provided,as the basis of programming application softvares.The article also describes the communication structure supported by a communication protrol SDLC.Accordingly,the basic design of a communication software is given.
