【摘要】 本文根据管网泄漏的实际情况设计并进行了管网水泄漏的模拟实验 ,对泄漏产生的信号进行了测试分析 ,采用互相关分析估计时间延迟来检测泄漏点位置 ,根据泄漏信号特征构造了人工神经网络模型 ,并用于泄漏点的检测 ,实验研究表明水管泄漏互相关法检测技术是适用可行的 ,但需要两个以上的传感器 ,而神经网络模型则只需一个传感器即可实现泄漏点的检测 ,体现了单传感器实现定位检测的良好前景更多还原

【Abstract】 In this paper,the simulated experiment were designed and carried out,the leakage points were detected by the estimated time delay with cross coherence and artificial nervous networks(ANN)model,the validities of two methods were demonstrated,especially the fruit results was given by the single sensor method based on ANN.更多还原
