Real-time leakage analysis method, equipment and system for water supply pipe network as well as storage medium

Abstract

The invention discloses a real-time leakage analysis method, equipment and system for a water supply pipe network as well as a storage medium. The method comprises the following steps of: establishinga simulation model of a to-be-managed water supply pipe network based on user water consumption of the to-be-managed water supply pipe network, inlet node pressure and pipeline parameters; obtaininga measured flow value of each node of the to-be-managed water supply pipe network; enabling the measured flow value of the node to match with a simulated flow value of a simulation model; and taking anode with matching failure between the measured flow value and the simulated flow value as a target node, and judging whether a downstream water supply pipe network of the target node has a leakage condition or not. A great number of ultrasonic flow meters are mounted in the to-be-managed water supply pipe network so as to reduce pipe network monitoring cost; the flow of the water supply pipe network is monitored in real time, and the simulated data obtained by the stimulation model is compared with the practically measured data of the water supply pipe network to determine the leakage condition of the water supply pipe network. The real-time leakage analysis method increases an accuracy rate of leakage detection, and shortens a detection period.

Description

technical field [0001] The invention relates to the technical field of water supply systems, in particular to a real-time leakage analysis method, equipment, system and storage medium of a water supply pipe network. Background technique [0002] Underground water supply pipelines often have pipeline aging or ground subsidence causing pipeline breakage and water leakage. At present, in addition to manual meter reading at the end of the water supply pipeline to analyze whether there is underground water leakage, there are many ways to actively detect leaks in the water supply pipeline network, such as at night The flow method, negative pressure wave method, regional meter installation method, and related leak detection methods are mostly obtained by monitoring and analyzing the pressure and flow history data of the water supply network during operation. Leakage points have disadvantages such as long cycle time, high false alarm rate, unpredictability of water leakage points, a...
