Method for managing urban water supply pipes

Abstract

The invention relates to a method for managing urban water supply pipes. The method comprises the following steps: establishing a water supply pipe network geographic information system to monitor water flow data in a water supply pipe network; placing a sound sensor at each monitoring point of the water supply pipe network to collect noise values of the water supply pipe at each monitoring point in the normal state of the water supply network; calculating the leakage performance index in each pipe network region and the water resource abundance index in each pipe network region in the water supply pipe network, and determining the pipe network regions required to be treated; calculating the active leakage control operation cost and the lost water cost of each leakage point in the network regions required to be treated, and determining the leakage points required to be treated in the network regions required to be treated. The method has the advantages that the water flow data of the pipe network can be monitored, leakage conditions of the water supply pipe network are determined, and leakage treatment strategies are provided, therefore, occurrences of post-event remediation are reduced, and the water loss and the operation cost of the pipe network are lowered.

Description

technical field [0001] The invention relates to the technical field of water supply pipe monitoring, in particular to a method for managing urban water supply pipes. Background technique [0002] Water supply pipe network leakage is a global problem. According to literature reports, the current global average pipe network leakage rate (the amount of water leaked from the pipe network divided by the total water supply) is 35%. Therefore, in order to save water resources and achieve sustainable development, it is necessary to reduce the leakage of pipe network. There are many reasons for the leakage of the pipeline network, such as damage to the main body of the pipeline, damage to the connection of the pipeline, leakage of pipeline accessories (gates, valves, fire hydrants, etc.). [0003] At present, the leakage monitoring of the pipeline network system often only relies on checking the leakage point where the pipe burst accident occurred, and then takes remedial measures a...

AI Technical Summary

Problems solved by technology

However, these leakage points have existed for a long time before pipe burst accidents usually occur, and thus caused a large amount of water resource loss and economic loss

In addition, once a pipe burst accident occurs, it will often cause a lot of waste of water resources, economic losses and even bad social impact
