摘要
在城际铁路信号系统中,通信控制服务器CCS是地面中心控制设备的重要组成部分,完成车-地通信、列车运行计划传输和车-地屏蔽门联控功能。ISDN服务器是CCS与车载ATP进行车-地无线信息传输的媒介,具有较高的可靠性和安全性。为此,分析CCS基本功能及ISDN服务器在CCS中的作用,介绍ISDN服务器的软硬件结构,描述ISDN服务器的通信功能模块CFM,设计CFM的层次结构、接口与流程。
In the signal system of intercity railway, communication ＆ control server, or CCS, is an im- portant part of the center control equipment on the ground, which realizes vehicle-ground communication, transmission of train operation plan and vehicle-ground united control function of platform screen doors. The ISDN server is the media for CCS and ATP wireless data transmission and should have high reliability ＆ safety. This paper analyzes the basic functions of the CCS and the roles of the ISDN server in the CCS, introduces the hardware and software structure of the ISDN server and describes the communication func- tion module of the ISDN server and give the design of the CFM＇s hierarchy, interface and process.
