摘　　要：目前供电企业电力通信光缆的安全性需求,利用三维图形技术,对电网通信光缆提出一种基于OpenGL与光时域反射仪的光缆监测系统。为实现该系统,文章首先对三维可视化技术进行了简单的介绍,并总结了在电力光缆应用可视化的必要性;其次,对该系统的整体架构进行搭建,并从硬件和软件的角度分别对该系统展开设计。在硬件方面,利用光时域反射仪的故障测距原理,对通信光缆的故障进行定位;在软件方面,重点就程控光开关和光时域反射仪的控制流程进行分析,进而得到完成对故障测试的方式选取,同时在故障定位方面,提出通过GIS对故障进行定位,同时运用OpenGL软件完成对监测结果的可视化。最后给出部分展示界面,验证了上述方案的正确性。At present,the security requirements of power communication optical cable in power supply enterprises are met.A monitoring system based on OpenGL and optical time-domain reflectometer is proposed for power network communication optical cable by using three-dimensional graphics technology.In order to realize the system,this paper firstly introduces the 3 d visualization technology and summarizes the necessity of applying visualization in power cable.Secondly,the overall architecture of the system is constructed,and the system is designed from the perspective of hardware and software.In terms of hardware,the fault location principle of optical time-domain reflector is used to locate the fault of communication cable.In terms of software,the control process of programmed optical switch and optical time-domain reflector is analyzed,and then the method of fault test is selected.Meanwhile,in terms of fault location,it is proposed to locate the fault through GIS.Meanwhile,OpenGL software is used to visualize the monitoring results.Finally,a partial display interface is presented to verify the correctness of the above scheme.
