基于GIS的通信光缆故障检修保障系统

光缆一旦发生故障将严重影响正常通信。为了解决光缆故障带来的严重后果，根据光缆网络在地理分布上的空间及环境特征，以地理信息系统(GIS)为基础对光缆及沿线信息实现空间数据库的管理和对故障位置的快速、准确定位，同时给出故障地点及周围的地形地貌等多媒体信息；结合GIS的缓冲区和路径分析功能，搜寻到达光缆故障点的最佳路径，并进一步给出处理故障的应急决策方案。该应用在有效的管理通信光缆资源，缩短抢修时间，减少因故障的发生而带来的损失方面取得了满意的效果。

Fault check & safeguard system of optical cable for communication based on GIS

Once fault occurs on the optical cable, it will seriously impair communication. In order to solve the terrible result caused by faults, the system implements the management of the spatial database of the optical cable and the information along it and location fault spots with celerity and legitimacy, according to the spatial and environmental characteristics on geographic distribution of the optical cable network and based on GIS, as it displays the multimedia information around the fault spot, such as landform and physiognomy. Combining the buffer with path analysis function of GIS, the system searches for the optimum path to the fault spot on the optical cable, and also gives emergency schemes to dispose the fault. This application has gained a satisfactory result for effectively managing communication optical cable resources, shortening the repair time, and diminishing the loss caused by faults.
