Dividing a water supply network into a plurality of DMAs according to the DMA partition principle of the urban pipe network (mainly according to the number of users, the monthly average water consumption and the length of a pipeline), arranging a flowmeter at the inlet of each DMA and continuously monitoring the minimum night flow of the DMA. If the minimum night flow fluctuates within a certain fixed range, the regional pipe network is in a normal state; if the minimum nighttime flow suddenly increases abnormally and does not fall back to a normal level for several consecutive days, it can be determined that there may be a loss in the area. When the flow data shows that the DMA is possibly leaked, the data of the water leakage and leakage recorder in the related area of the DMA is rapidly collected and subjected to signal analysis, and the position of a leakage point in the DMA is further judged. The steps involved in this scheme are explained below:
1) and (3) according to data such as urban pipe networks, roads, rivers and the like, comprehensively considering the size of the DMA (including the number of users and the length of a pipeline), and dividing the boundary of the temporary DMA. The basic indexes of the temporary DMA are counted, and the basic indexes mainly comprise: the number of users, the monthly water consumption and the length of the pipeline. And adjusting the number of the temporary DMA users and the length of the pipeline to obtain formal DMA, wherein each index of the DMA needs to be counted again after adjustment, the number of the DMA users is about 3000, the length of the pipeline is about 10 kilometers, and the index of the length of the pipeline has priority. And finally, selecting parameters of a water inlet and a flowmeter, and checking whether the DMA needs to install a new valve and a new pipeline or not to ensure the integrity and the independence of the pipeline in the DMA.
2) A flow meter (such as a pipeline type electromagnetic flow meter and an ultrasonic flow meter) with a data storage function is installed at a water inlet of the DMA, and is connected with a data storage to store flow data.
3) And carrying out comprehensive manual leak detection on the DMA, and quickly repairing the DMA after finding the leak, so as to ensure that the phenomena of tube explosion and the like do not exist in the DMA.
4) After manual leak detection and leakage repair, DMA flow data is continuously monitored for more than 30 days, for recorded daily flow data, the minimum continuous value on the current day is taken as the minimum night flow on the current day (generally occurring between 1:00 and 5:00 in the early morning), and the obtained minimum night flow on the current day and the corresponding date are plotted to form a minimum night flow curve. The fluctuation range of the curve is the normal fluctuation range of the DMA minimum night flow, and the fluctuation center is the normal value of the minimum night flow.
5) And after determining the normal fluctuation range of the minimum night flow of the DMA and the normal value of the minimum night flow, periodically and manually downloading DMA flow data stored in the data memory, wherein the downloading period is between 7 and 14 days. Judging whether DMA is missed or not according to the change condition of the minimum night flow curve in the downloading period:
i) if the minimum night flow curve has any one or any two or more of the following three conditions:
a) the curve fluctuates up and down on the normal value, and the fluctuation range is within the normal fluctuation range; b) The occasional discontinuous minimum night flow increase occurs and exceeds the normal fluctuation range; c) The data downloading date is that the data is returned to the normal value, and the difference value of the data and the normal value is not beyond the normal fluctuation range. It is determined that there is no leak in the DMA internal water supply pipeline.
ii) if the minimum night flow curve continuously rises until the date of data downloading still does not fall back to the minimum night flow normal value, the minimum night flow change trend of the DMA is monitored and tracked with emphasis. If the minimum night flow value of the DMA exceeds the minimum night flow normal value within 5 consecutive days, judging that the DMA has a loss risk and needing subsequent loss monitoring; if the minimum night flow value is recovered to the normal value within 5 days, subsequent leakage monitoring is not needed.
6) And according to the judgment result of the minimum night flow curve of the flowmeter, performing leakage monitoring and troubleshooting and leakage point positioning on the DMA with leakage risk by using a leakage recorder. The specific operation steps are as follows:
first, a loss recorder is installed on a DMA area water supply network. The layout principle of the leakage recorder is as follows: for the pipeline with the diameter of 75 mm-200 mm, the arrangement distance of the leakage recorder is 150 m-200 m; for the pipeline with the diameter of 200 mm-400 mm, the arrangement distance of the leakage recorder is between 100 m-150 m. The leakage recorder is arranged on an auxiliary structure of the pipeline, wherein the auxiliary structure refers to any one of an inspection well, a fire hydrant, an exhaust valve, a gate and the like. Then, the DMA is subjected to drop-out signal collection. In any day from 2 nd day to 6 th day after the arrangement of the leakage recorder, the portable signal collection host passes through the vicinity of the arrangement position of the recorder at a speed of less than 30km/h, wherein the distance between the signal collection host and the leakage recorder is within 20 m; the signals recorded by the leakage recorder are received by the host computer, and then whether leakage exists or not is determined and a leakage point is determined.
7) And dispatching workers to go to the leaking pipe sections for checking and confirming according to the information of the leakage recorder, and repairing the determined leakage points.
8) And after repairing the leakage points determined by the investigation, re-collecting the data of the inlet flow meter, and further judging whether other leakage still exists in the DMA area by using the method. If the minimum night flow value of the DMA exceeds the minimum night flow normal value within 5 consecutive days, judging that the leakage risk still exists, and continuing to use the analysis result of the leakage recorder to carry out leakage point positioning and manual repair until the DMA has no leakage. If the difference between the minimum night flow value and the minimum night flow normal value of the DMA is within 10% within 5 consecutive days, the DMA is judged to have no leakage risk, and a leakage recorder is not required to be used for leakage monitoring and troubleshooting.
