近年来贵州省高速公路通车里程不断增加,直至目前已近3000km,路网规模逐渐形成,作为联网收费、监控支撑的通信光缆线路维护管理的及时性愈显重要。所以实时有效地掌握光缆线路状态、定位故障、故障报警,能有效地做到故障预防、减少故障相应及处理时间、减少故障排查的维护成本、降低因光缆故障时间过长造成的瘫痪性影响;所以将光缆监测系统应用于高速公路是做好长距离光缆线路维护的重要手段。
In recent years, the mileage of expressways opened to traffic in Guizhou Province has been increasing. Up to now, nearly 3,000km has been formed, and the scale of the road network has gradually taken shape. As the cost of networked toll collection and supervision, the timeliness of maintenance and management of communication optical cable lines becomes more and more important. Therefore, real-time and effective control of fiber optic cable line status, location fault, fault alarm, can effectively prevent failures, reduce the corresponding fault and processing time, reduce troubleshooting and maintenance costs and reduce the fiber optic cable failure caused by the long time paralysis; Therefore, the application of fiber optic cable monitoring system is an important means of maintaining long-distance fiber optic cable lines.
