Pipe explosion positioning method based on particle swarm optimization

Abstract

The invention relates to a pipe explosion positioning method based on particle swarm optimization. The pipe explosion positioning method comprises the following steps that S1, pipe explosion judgmentis conducted, specifically, water balance calculation is performed according to real-time SCADA flowmeter data, whether the pipe explosion situation possibly occurs or not is judged according to whether the water balance difference value exceeds the threshold value, if the pipe explosion situation possibly occurs, a real-time model calculation result is compared with the SCADA pressure data, if the pressure reduction exceeds the threshold value, it shows that pipe explosion occurs, alarming is conducted, otherwise, suspected pipe explosion is judged, and staff members are reminded to maintainonline monitoring equipment; S2, water balance calculation is performed according to real-time SCADA flowmeter data, and whether the pipe explosion situation possibly occurs or not is judged accordingto whether the water balance difference value exceeds the threshold value; and S3, pipe explosion positioning is conducted, specifically, when the pipe explosion incident occurs, the particle swarm optimization is called to determine the possible pipe explosion position.

Description

technical field [0001] The invention relates to the technical field of urban water supply pipe network, relates to the location of leakage points of the water supply pipe network, and in particular to a burst pipe location method based on particle swarm algorithm. Background technique [0002] Pipe burst accidents are often faced by water supply companies. When a pipe burst accident occurs in the pipe network, the amount of water leakage is very large in a short period of time, resulting in a large waste of water resources, and even causing water cutoff in some areas, affecting the normal life of residents and the operation of enterprises. The leakage caused by the explosion accident of large-diameter pipelines will flood the ground, causing water accumulation in the streets on the ground and blocking traffic. Severe pipe explosion accidents may also cause flooding accidents in parking lots and low-rise buildings. After the pipe burst accident, due to the connection between...

When a pipe burst accident occurs in the pipe network, the amount of water leakage in a short period of time is very large, resulting in a large waste of water resources, and even causing water cutoff in some areas, affecting the normal life of residents and the operation of enterprises

The leakage caused by the explosion accident of large-diameter pipelines will flood the ground, causing water accumulation in the streets on the ground, blocking traffic, and serious pipe explosion accidents may also cause water ingress accidents in parking lots and low-rise buildings

After the pipe burst accident, due to the connection between the pipeline and the outside world, when the pressure at the breach of the pipeline drops, pollutants will enter the pipeline network, causing secondary pollution of the pipeline network
