摘要
针对通信光缆故障点位置及故障类型判断困难,维护效率较低等问题,提出了一个基于地理信息系统GIS的故障智能决策方法,根据光时域反射仪OTDR的基本工作原理及其在光缆接续点测量中各种接续点衰减曲线的特征,设计了专家系统的相关知识规则,并且结合通信光缆维护的具体特点和要求,建立了一个光缆沿途区域的GIS系统,以实现通信光缆维护的信息化和智能化,提高了光缆维护工作的维护效率.
Aiming at the difficulty optical cable-maintaining, this paper issues an intelligent diagnosis system based on GIS and expert system. To improve the optical cable-maintaining efficiency, the rules of the expert system are established according to the characteristic of the optical cable faults in the OTDR output. And the GIS is also established contained the information of the optical cable and the region the cable locates in.
