数据转发在城市轨道交通综合监控系统中的应用

地铁综合监控系统是一个功能庞大的信息系统,同时又是一个多功能、多专业子系统的集成互联系统。综合监控系统需要与相关子系统进行数据交换转发及控制信息的下发。结合广州珠江新城APM(旅客自动输送)系统中的综合监控系统,分析各车站子系统向控制中心转发数据、控制中心向各子系统下发控制命令的模型及流程,并得出控制中心处理后的控制命令的数据交换方案。

Application of Data Transfer in ISCS of Urban Rail Transit

Metro integrated supervision and control system(ISCS) is a system with enormous information functions,and also an interconnection system covering plural functions and professional sub-systems,it exchanges data with relevant sub-systems and distributes control information.With an analysis of Guangzhou automatic passenger movement(APM) ISCS,this paper describes the process of data transfer from the control center to station subsystems and vice versa,and obtains a data exchange scheme of control commands after the processing of the control center.
