【摘要】 介绍了一种输油管道泄漏实时在线监测系统,该系统采用瞬态负压波法结合小波变换,实现从噪声中准确提取泄漏信息,并通过通讯网络将现场信息传送到控制中心显示和报告,进而完成管道泄漏点的定位、报警及实时监测等功能,具有很好的实用价值。更多还原

【Abstract】 A real-time monitor system in oil pipeline leakage was introduced.This system adopted the method of transient minus-press wave combining wavelet transform,implemented drawing information of leakage accurately from noise,through communication network field and sent message to the control center,and then finishing such functions as the localization that the pipeline leakage clicked,alarm,and monitoring in real-time,etc.,which values greatly in actual application.更多还原
