Sensor distribution system and method for water supply pipe network

Abstract

The invention provides a sensor distribution system and method for a water supply pipe network, and relates to the technical field of water supply pipe network monitoring. The sensor distribution system comprises a topology establishment module for establishing a pipe network topology structure, a data acquisition module for acquiring normal operation data of all pipe segment nodes, a first processing module for processing and obtaining real-time operation data corresponding to all the pipe segment nodes when the normal operation data of each of the pipe segment nodes changes, a second processing module for processing according to the normal operation data and the real-time operation data to obtain influence change values of all the pipe segment nodes, a data comparison module for outputting comparison results when the influence change values are less than a preset change threshold value, and a topology output module for removing the corresponding pipe segment nodes from the pipe network topology structure according to the comparison results and obtaining a pipe network topology optimization structure so as to distribute sensors according to the pipe network topology optimization structure. The sensor distribution system and method for the water supply pipe network can enable a monitoring area of the whole water supply pipe network to be covered with the minimum number of sensors, and achieve high universality.

Description

technical field [0001] The invention relates to the technical field of water supply pipe network monitoring, in particular to a sensor point distribution system and method for a water supply pipe network. Background technique [0002] The urban 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. With the advancement of pipe network informatization and smart water affairs, changes in the pressure, flow, water quality and other parameters of the pipe network can be monitored in real time through the urban water supply pipe network, and the leakage and abnormal situation monitoring and rapid positioning of the pipe network can be realized. The monitoring of the urban water supply network needs to rely on the data acquisition sensors deployed in the water supply pipe section of the urban water supply network to collect various parameters of the entire water sup...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the layout of urban water supply pipe network data collection sensors is usually based on actual application requirements, such as maximum monitoring of pipe network pressure, maximum monitoring of water quality abnormalities, maximum monitoring of pipe network flow conditions, etc., due to data collection sensors The layout is usually aimed at specific monitoring objectives, such as water pressure, water quality or flow, etc., and has poor versatility. It cannot achieve effective monitoring of multiple monitoring objectives at the same time, and cannot comprehensively and accurately obtain the real-time operating status of the water supply network.
