本文提出了一种应用智能水技术检测漏水的方法。这种方法包括使用传统的水平衡方法和最小夜间流量方法。这一程序已应用于在里尔大学科学校园进行的一个大规模试点项目，该大学的规模相当于一个小镇。校园的供水网络由一组传感器监控，这些传感器实时记录和传输供水系统的水力参数。通过对实时数据的分析，可以核实水平衡并估计管网中的水损失水平。本文提出了一种基于流量阈值确定的最小夜流量法的应用改进方法。如果夜间流量超过阈值，则会生成泄漏警报。这种数据分析方法提供了快速检测管道爆裂的能力，从而减少了泄漏的运行时间。应用改进的方法可以检测到25个未报告的泄漏，并将无收益水（NRW）水平降低了36%。
This paper presents a methodology for the application of the Smart Water technology to detect water leakage. This methodology consists in the use of the traditional water balance method together with the minimum night flow approach. This procedure has been applied to a large-scale pilot project conducted at the Scientific Campus of the University of Lille, which is the size of a small town. The water network of the campus is monitored by a set of sensors that record and transmit, in real-time, the hydraulic parameters of the water system. Analysis of real-time data has allowed the verification of water balance and the estimation of water losses level in the network. The paper presents an improvement of the application of the minimum night flow method, which is based on the determination of flow thresholds. A leak alarm is generated if the night flow exceeds the thresholds. This data analysis methodology provides the capability to detect the pipe bursts quickly, thereby reducing the runtime of leakage. The application of the improved method allowed the detection of 25 unreported leaks and decreased the Non-Revenue Water (NRW) level by 36%.
