Online leakage monitoring method for urban water supply pipe network

Abstract

The invention relates to an online leakage monitoring method for an urban water supply pipe network. The method comprises the following steps: water flow speed sensors are mounted at joints of water supply pipes, pipe segments prone to leak and pipe segments leaking frequently, so as to monitor the water flow speed in real time; the number of the sensors is counted, each sensor mounting point is used as a test point, each monitoring point regularly uploads the water flow data of the monitoring point to an upper computer system, and the water flow data are used for leakage analysis and judgment; the upper computer system receives the real-time water flow speed and then sends the water flow speed to a monitoring end in a wireless communication manner through a wireless communication module connected with the upper computer system; the monitoring end receives the real-time water flow speed sent by each test point and judges whether the water supply tubes leak; when the water pipes leak, the water flow speeds of all the test points are compared and analyzed to judge leakage points of the water pipes. The method has the advantages that steps are simple, implementation is facilitated, monitoring directed at the water supply pipe network can be achieved to the greatest extent, waste of water resources is prevented, and the water supply stability of the water supply pipe network is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water supply pipe monitoring, in particular to an on-line monitoring method for urban water supply pipe network leakage. 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] The traditional method of pipeline leakage inspection is artificial listening inspection. In order to avoid interference from the surrounding environment and res...

However, since these detected signals will fade as the distance becomes longer, and when collecting information, it is necessary to install collection devices on the water pipe at intervals, the cost is high, and the negative pressure wave and vibration sound are easily affected by factors such as medium and environmental noise.
