摘要
设计了管道泄漏计算机在线检测系统的总体结构,提出了一种基于工况分析的逻辑判决故障检测算法.当输油管道工作状况不断发生改变时,这种方法能够动态估计管道运行数据的正常值范围,很好地解决输油管道泄漏的故障检测问题,结合GPS技术和负压波定位算法,大大提高了报警准确性和定位精度.现场测试结果和实际工业应用证明了该方法的有效性.
The architecture of the on-line computer detecting system of pipeline leak is designed, and a kind of logical judge fault detection algorithm based on working status analysis is proposed. Under the condition that working status frequently changes during transferring oil, the fault detection of oil pipeline leak can be improved commendably by employing this method, which can estimate the natural range of pipeline running data. The alert veracity and location precision can be consumedly improved by combining GPS technology and negative pressure wave location algorithm. The locale testing results and practical industrial application show validity of this method.
