Pipe Network Leakage Monitoring Method

Abstract

The invention discloses a pipe network loss monitoring method. The method comprises the steps of constructing a DMA (direct memory access); performing real-time and continuous monitoring and recording flow data at a pipe network area to be monitored; recording alarming information of an acoustic loss detection device in real time; extracting minimum flow of every night and constructing a flow-time curve of the minimum flow of the night; judging whether loss exists or not; if not, continuing collecting the flow data and alarming information; if yes, searching for and confirming a loss point; weighing cost and profit of repairing the loss point, and determining whether the loss point needs to be repaired or not; if not, continuing collecting the flow data and alarming information; if yes, completing the repair of the loss point and continuing collecting the flow data and alarming information. According to the pipe network loss monitoring method, the defect that loss amount cannot be determined by a method based on acoustic signal monitoring and the defect that a loss location is difficult to determine by a method based on flow monitoring can be specifically overcome, and loss monitoring efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of leakage detection of a water supply pipe network, in particular to a method for monitoring the leakage of a pipe network. Background technique [0002] Water supply network leakage is a global problem. According to literature reports, the current global average network leakage rate (the amount of water leaked from the 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 pipe network leakage. 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.). In order to reduce the leakage of the pipe network, the location and size of the leakage must be detected in order to deal with it accordingly, such as repairing damaged points, updating pipe ...
