城市轨道交通综合信息网业务接入的实现

Service Access of Integrated Communication Networks for Urban Rail Transit

为实现城市轨道交通网络化运营较高的资源共享率以及较强的协调运营能力,首先对城市轨道交通控制中心各业务系统的通信需求进行分析,根据需求分析结果获取各业务系统传输信息业务的种类以及业务容量的大小;然后,对综合通信网的组成与功能定位进行描述;最后,根据信息传输种类以及业务容量大小等因素,确定综合通信网上层系统和控制中心业务系统接入综合信息网的接口类型与相关通信协议。

In order to achieve a higher rate of information resource sharing and better coordinated operation,first,the communication requirements of the urban rail transit control center are analyzed,and the type of service and the capacity of the information of each service system are obtained according to the demand analysis. Then,the composition and function of the integrated communication network are described. Finally,according to the information types and the information capacity,the interface types and related communication protocols of integrated communication networks have been determined.
