无线接收总站的功能是将发射子站及中继站送来的无线信息接收后进行解调。解调后的数据送通讯主站,由通讯主站进行解码处理。
2. 2.5 通讯主站
通讯主站主要是接收无线解调后的信息,然后解码并对数据进行处理,最后将数据送往相关设备。
通讯主站具有如下接口:
(1). 无线数据接口:接收无线接收总站解调后的数据,再进行解码处理,恢复FD的地址码信息。
(2). 与监控中心的接口:串口(RS-232),将无线数据接口接收到的FD的地址码信息送入监控中心的计算机系统。
(3).与配电管理系统(DMS)中心的接口:可向DMS 系统发送故障信息,接收DM S 系统的查询。
通讯主站木身带有 LCD显示及两个操作键,可通过LCD 及操作键,直接查询故障线路信息,及在必要时清除内存等;在接收到故障信息后还可以给出音响报警。
2. 2.6 基于GIS平台的故障定位系统软件
定位系统软件是监控中心的核心组成部分,它的主要作用是搜集通讯主站传送的地址信息,对其进行纠错、校正后,通过拓扑分析和计算找出故障位置及故障通路,最终显示在GIS 地理背景上。
(1) 故障指示器动作信息和网络拓扑数据的实时搜集
故障定位系统在收集故障指示器动作信息和网络拓扑数据时,要遵循以下两个基本原则:
① 故障指示器动作信息的完整性原则
一般来讲,各故障指示器的动作信息到达通讯主站的时间是不同步的,在一个采样周期内采集到的故障指示器动作信息很可能是不完整的。因此,该系统假定:如果在若干个周期内没有新的故障指示器动作信息到达,则故障指示器动作信息已经搜集完整。这样,即使在系统发生多重故障时,也能够保证故障指示器动作信息的完整性。
