面向光纤通信工程的光缆线路敷设管理系统设计

Design of optical cable line laying management system for optical fiber communication engineering

由于光纤通信工程的实施需要复杂的光缆线路敷设施工,难以保障光缆线路敷设的质量,设计面向光纤通信工程的光缆线路敷设管理系统。硬件上,选择树莓派3B+作为主控芯片,采用GTLD-5CAPDSU组合光器件作为OTDR的核心器件。软件上,在光纤通信工程准备阶段通过蚁群算法规划光缆线路敷设路径;在光纤通信工程施工阶段基于三点时间估算法对光缆线路敷设进度进行管控;在光纤通信工程竣工阶段使用OTDR探测技术检测光缆线敷设质量。测试结果表明,设计系统可以对光缆线路敷设故障作出响应,并根据OTDR探测信号对故障准确定位,进而保障敷设质量。

Because the implementation of optical fiber communication engineering nceds complex optical cable laying construction,it is difficult to guarantec the quality of optical cable laying,and the optical cable laying management system for optical fiber communication engineering is designcd.In terms of hardware,Raspberry PI 3B+was selected as the master chip,and GTLD-5CAPDSU combined optical device was used as the core device of OTDR.In software,the optical cable line laying path is planned by the ant colony algorithm in the preparation stage of optical fiber communication engincering,controls the laying progress of optical cable line based on the threc-point time estimation method in the construction stage of optical fiber communication engineering,and uses OTDR detection technology to test the laying quality of optical cable.The test results show that the design system can respond to the fault of the optical cable line laying,and accurately locate the fault according to the OTDR detcction signal,so as to ensure the laying quality.
