摘要
针对油气管道监测方面的应用,提出一种基于光时域反射仪(OTDR)技术的光缆监测方案,该光缆断缆故障定位告警系统可对油气管道的伴行光缆进行实时监测,并通过对比标准测试曲线和实时测量曲线的差别,自动分析出整条光缆线路是否存在异常,若存在异常则确定异常位置并向监测中心发出短信告警。
In application to monitoring the oil and gas transportation pipeline, a scheme of fiber cable monitor- ing which is basing on the optical time domain reflector technology is proposed, and the system of fiber cable broken fault locating and warning is developed. The system is using for monitoring the accompanying cable of the oil and gas transportation pipeline in real-time, by comparing the difference between the real-time curve and the standard curve, and automate analyzing the hole cable line and make sure is there any abnormal event or not. If there is an abnormal event in the real-time curve, then find out the location of it and then send the warning text message to the monitor center.
