摘要
参照城市轨道交通综合监控系统工程设计规范(GB 50636—2010),研究综合监控系统与信号系统在中心、车站和就地级的接口方式,更好地实现互联互通和系统间联动。中心采用基于Modbus TCP协议的冗余前置机进行通信,故障后可自动切换从而有效提高系统可靠性,就地级采用紧急后备盘硬线连接信号设备。详细并超前设计出系统在中心的传输点类表,实现列车、站台、供电区、火灾报警以及客流预警等消息的传输,为实际现场和实验室仿真条件下的系统间接口开发提供借鉴。
Referring to Code for design of urban rail transit integrated supervision and control system engineering （GB 50636- 2010）, this paper studies the types of interface between the integrated supervision and control system and the signal system at the center, station and local levels, aiming to achieve better connectivity and interoperability. Redundant communication based on Modbus TCP protocol at center stage improves system reliability effectively, which can automatically switch after failure. At the local level, the integrated backup panel connects signal equipment via hardwire. An advanced and detailed point class table was proposed to realize information transmission, including trains, stations, power supply areas, fire alarm and passenger flow warning, etc.
