摘要
针对传统光缆故障诊断系统存在的诊断精度低的问题,利用故障树技术,从硬件、数据库和软件功能三个方面,实现对铁路通信光缆故障诊断系统的优化设计。安装光功率计和光时域反射仪设备,并改装系统控制器设备。收集光缆实时运行数据和历史故障诊断数据,按照一定的存储格式,实现对系统数据库的构建。在硬件设备和数据库的支持下,分析铁路通信光缆的工作原理,并构建相应的故障树。提取通信光缆运行特征,通过故障概率的计算,确定光缆的故障类型,综合光缆故障的定位结果,实现铁路通信光缆故障诊断功能。通过系统测试实验得出结论:与传统故障诊断系统相比,设计系统在故障数量与故障位置两个方面的诊断误差均有所降低,即在诊断精度方面更加具有优势。
Aiming at the problem of low diagnosis accuracy in the traditional optical cable fault diagnosis system, the fault tree technology is used to optimize the design of railway communication optical cable fault diagnosis system from three aspects of hardware, database and software function. Install optical power meter and optical time domain reflectometer equipment, and retrofit system controller equipment.The real-time operation data and historical fault diagnosis data of optical cable are collected, and the system database is built according to a certain storage format. With the support of hardware equipment and database, the working principle of railway communication optical cable is analyzed, and the corresponding fault tree is constructed. The operation characteristics of communication cable are extracted, and the fault types are determined by calculating the fault probability, and the fault diagnosis function of railway communication cable is realized by integrating the fault location results.Through the system test experiment, it is concluded that compared with the traditional fault diagnosis system, the diagnosis error of the designed system in both fault number and fault location is reduced, that is, it has more advantages in diagnosis accuracy.
