Newly-added leakage judgment and leakage rate estimation method suitable for water supply pipe network in underdeveloped area
The invention discloses a newly-added leakage judgment and leakage rate estimation method suitable for a water supply pipe network in an underdeveloped area. The method comprises the steps of installing a boundary valve at the boundary of the area to realize the water supply closeness and independence of the area, and installing a flow meter on a main water supply pipeline to carry out real-time field monitoring on the water supply condition of the area; screening data samples according to seasonal differences and climate differences, carrying out mean value calculation and function fitting on the daily average water consumption of residents in the area, and taking the positive and negative 3-times standard deviation of a daily water consumption mean value curve of the residents as a boundary range; conducting comparison and analysis on newly acquired monitoring data and the boundary range, and reasonably judging whether the pipe network has newly-added leakage or not; and meanwhile, approximately using the minimum value of the water consumption of the residents as the leakage flow, calculating the pipeline leakage rate, and being capable of achieving real-time updating and correction of the leakage rate. The method is particularly suitable for the underdeveloped area where user water meters do not have automatic collection and transmission functions, the application range is wide, the implementation feasibility is high, the method is simple and efficient and has the broad engineering application prospect, and the social and economic benefits are remarkable.
本发明公开了一种适用于欠发达地区供水管网新增漏损判别及其漏损率估算方法，通过在区域边界安装边界阀，以实现区域的供水封闭性及独立性，并在主供水管道安装流量计，对该区域供水情况进行实时现场监测；根据季节及气候差异筛选数据样本，对该区居民日平均用水量进行均值计算及函数拟合，并以居民日用水均值曲线的正负3倍标准差作为边界范围；将新获取的监测数据与边界范围进行对比分析，对管网是否有新增漏损进行合理的判断；同时，以居民用水量的最小值作近似为漏损流量，计算管道漏损率，并能实现漏损率的实时更新与修正。此方法尤其适用于用户水表不具备自动采集及传输功能的欠发达地区，适用范围广，实施可行性高，且方法简单高效，有着广阔的工程应用前景，社会及经济效益显著。
