Embodiment Construction

[0038] The automatic identification and positioning method of water supply pipe network leakage proposed by the present invention, its flow chart is as follows figure 1 shown, including the following steps:

[0039] (1) Set a total of N monitored pipe sections in the independently metered water supply pipe network, install sensors on the n pipe sections, 0≤n figure 2 shown;

[0040] (2) Training and test data collection: In the time period K (for example, 100 weeks), with the sampling frequency t (for example, 4 data / hour), use the sensor in step (1) to measure the physical state of the water supply network (such as flow or pressure), and record the leakage status of the monitored pipe section at the same time to obtain a data set D = (X, Y), where X is a data group composed of data collected by all sensors, and Y is the leakage of all monitored pipe sections In the data group composed of state, record Y as 1 for the leakage state of the pipe section, and record Y as 0 for th...

Abstract

The invention relates to an automatic identification and locating method for leakage of a water supply network, and belongs to the technical field of leak monitoring of the water supply network. The method comprises the following steps of acquiring the physical states of limited pipe sections which are independently metered in the water supply network by using sensors; recording the leakage statesand positions of the pipe sections; establishing, training and testing a deep neural network; identifying the leakage state of a complex water supply network by analyzing data of a few sensors; and specifically locating water pipe sections with leakage. The method provided by the invention is implemented by specific steps, and the result is stable and reliable by means of an accuracy test method,so that the method has high feasibility. When the method is used for monitoring the water supply network, the identification and locating of the leakage of the entire water supply network can be realized with a limited number of sensors, so that the monitoring cost is low, and the monitoring accuracy is high. Moreover, the repair for the leakage of the water supply network can be accelerated greatly, and the water resource loss, resource waste and water quality pollution caused by leakage are lowered.

Description

technical field [0001] The invention relates to an automatic identification and positioning method for water supply pipe network leakage, and belongs to the technical field of water supply pipe network leakage monitoring. Background technique [0002] The leakage of urban water supply pipe network is a common and important problem, which has aroused widespread concern in the society. The leakage of the water supply pipe network is sometimes difficult to be identified and located, resulting in delays in maintenance time, resulting in a large loss of water resources and increasing the pressure on water supply demand. The leakage of the pipe network may affect the water quality of the water supply, and also cause the release of pressure in the pipe, resulting in a waste of energy. In the context of increasingly severe environmental and energy crises, the identification and location of water supply network leakage is of great significance, which will help save water resources a...
