车站列控中心接口系统功能概述

列控中心为了满足控车要求,需要从CTC、联锁设备、轨道电路、TSR服务器等设备接口获得信息,结合这些信息进行逻辑运算用以确定应答器报文、产生轨道电路编码,形成给CTC和联锁设备的信息。列控中心需要与多个系统接口,接口的标准化是保证这些设备信息互通的前提。郑西客专的LKD2-H型列控中心设备由于内部采用串行总线,通过智能化的接口模块实现外部接口与内部总结的桥接,对应开发一种新的接口时,只需要开发相应的接口适配板即可,不会改变体系结构,可扩展性强。接口模板实现了智能化,可以有效降低系统的复杂性,从而提高系统的可靠性、可维护性、可扩展性、通过采用安全的应用层协议,实现信息传输的安全逻辑。

Station train control center interface system function

the train control center in order to meet the requirements of control car,need from CTC, interlock device, track circuit, TSR servers and other equipment interface access to information,combining these information to carry out logical operation is u.~ed to determine the Balise Telegram,produced track circuit coding,formed to CTC and interlocking equipment information.The train control center and multiple interface system,interface standardization is to ensure the premise of these devices to exchange information. Zhengxi special passenger transport line of type LKD2-H equipment for train control center due to internal serial bus, through the intelligent interface module external interface and internal summary of the bridge,the corresponding development of a new interface, only need to develop the corresponding interface adapter plate, does not change the architecture,sealability.lnterface template to realize the intellectualization,can effectively reduce the complexity of the system,so as to improve the system reliability, maintainability, extensibility, through the use of security application layer protocol,to realize the information transmission security logic.
