光纤通信网络凭借其丰富的带宽资源、数据传输的高速率、理想的抗干扰性以及其较低的成本,已经成为电力通信骨干网的首选。电力光纤通信网络目前已经具有较为可观的规模,对电力传输系统的安全稳定以及电力通信系统的畅通起到至关重要的作用。因此,光传输网络的自愈性已成为至关重要的问题。本系统采用1:1的光路保护模式,系统可分为光功率的监测、计算模块,控制模块、以及光开关切换模块。并采用ARM+Linux的架构,开发出一套大范围、高精度、高稳定性的光路保护硬件系统。经过实验与测试,该切换系统的切换速度能达到44ms。该硬件系统运行稳定、可靠,切换速度达到了预定的目标:50ms,满足电力光纤通信的要求,具有重要的实用价值。

Optical fiber communication network, with its abundant bandwidth resources, high-speed data transfer rate, the ideal anti-interference and its low cost, has become the preferred power communication backbone. Power optical fiber communication network now has a more substantial scale, security and stability as well as the smooth flow of power to the communication system of power transmis-sion systems play a crucial role. Therefore, self-healing optical transmission network has become a criti-cal issue. The system uses a 1:1 optical protection mode, the system can be divided into optical power monitoring, calculation module, control module, and an optical switch module. Using ARM+Linux archi-tecture, developed a large-scale, high-precision, high stability of the optical path protection hardware system. Through experiments and testing, the switching speed of the switching system can reach 44ms. The hardware system is stable, reliable, and switching speed reaches intended target:50 ms, meet the re-quirements of the power of optical fiber communication has important practical value.
