摘要
为了给供水行业快速检漏及定位提供参考,对比了基于硬件及模型算法的检漏方法,分析了适用范围及特点。分析认为:基于硬件的检漏方法主要建立在声学、光学反射原理及电信号传递等基础上,具有较高的精度,但耗时耗力且成本高;基于模型算法的检漏技术建立在管网节点压力、流量特征的基础上,通过模型模拟值与测量值之间差值最小化的优化算法可快速定位可能的漏损点,但位置存在一定偏差;建议将两种检漏方法相结合,充分发挥彼此的优势,为自来水厂快速精准检漏提供思路。
In order to provide references for quick leakage detection and location in water supply industry,the leakage detection methods based on hardware and model algorithm were compared.The application scope and characteristics of the methods were analyzed.The analysis shows that the hardware-based leakage detection methods are developed mainly based on acoustics,optical reflection principle and electric signal transmission.These methods have high accuracy,but high time and energy consumption cost.The model algorithm-based leakage detection technologies are based on the node pressure and flow characteristics of pipe networks.The possible leak points can be quickly located by the optimization algorithm obtained by minimizing the difference between model simulation value and measured value,but there is a certain deviation in the location.It is suggested to combine the two leakage detection methods to maximum their advantages and provide ideas regarding rapid and accurate leakage detection for waterworks.
