Embodiment 1

[0093] This embodiment discloses a method for locating multi-point leaks in a municipal water supply network based on a convolutional neural network. The specific implementation steps are as follows:

[0094] Step 1. Collect the pressure data of the water supply network by type, including normal data, single-point leakage and multi-point leakage data, and put a unique label on each piece of data according to the type (the data labels of the same type are the same) , divide the labeled data into training samples and test samples, and normalize the training samples and test samples respectively.

[0095] Step 1.1 The water supply data is collected every 5 seconds through the sensors installed on the water supply network around the clock. The data includes one set of normal data, four sets of single-point leakage, two-point leakage, and three-point leakage data. The types of leakage points are shown in Tables 1 and 2, and each data format is {23.421747, 23.721256, 22.024464...21....

Description

technical field [0001] The invention relates to the field of municipal water supply pipe networks, in particular to a multi-point leakage location method and device for water supply pipe networks based on convolutional neural networks. Background technique [0002] The municipal water supply network is an important infrastructure to ensure a city's economic development and living standards, and is the lifeline of a city's survival and development. However, due to the continuous expansion of water consumption and the increase in the service life of the pipe network, there is a lack of a modern, intelligent, and theoretical municipal water supply pipe network management system, and the municipal water supply pipe network has gradually exposed a wide range of leakage. , will cause waste of water resources and economic losses. [0003] With the development of science and technology and the continuous improvement of water supply requirements, it is imminent to establish a water ...
