城市供水管网泄漏频谱与预警参数研究
|
摘要
以傅里叶变化为理论方法,系统地研究了供水管网泄漏传播规律和泄漏噪音的频谱,提出了以供水管网泄漏的最小噪音水平为主参数,泄漏噪音的频谱、带宽以及泄漏噪音强度分布为辅助参数的供水管网泄漏和爆管判别与预警标准.这些泄漏预警参数的有效性通过广州市花都区自来水公司的实测数据得到了验证,取得了满意的效果.
This paper systematically researches on the propagation characteristics and noise spectrum of water leakage by utilization of Fourier transform methodology,and it puts forward a criteria of Minimum Noise Level as key parameter and noise spectrum,the band and noise intensity distribution as auxiliary parameters to judge or early warn water leakage or pipe burst of water distribution network. The effectiveness of these parameters is verified by the site monitoring datum of water distribution network of Guangzhou Huadu Water Utility.
