Water supply pipeline leakage point detection system and method based on flexible pipeline robot

Abstract

The invention provides a water supply pipeline leakage point detection system and method based on a flexible pipeline robot, and relates to the technical field of water supply pipeline leakage point detection. The system comprises the flexible pipeline robot and an upper monitoring terminal; the flexible pipeline robot is used for performing real-time positioning in a walking process to obtain real-time positioning time and real-time position information, and outputting pressure abnormal change time and real-time position information when pressure abnormal change of a water supply pipeline isdetected; and the upper monitoring terminal comprises a track generation module used for generating a walking track according to the real-time positioning time and the corresponding real-time positioninformation, a first marking module used for giving a leakage point mark on the walking track according to the real-time position information corresponding to the pressure abnormal change moment; anda second marking module used for marking the walking track containing the leakage point marks on a pre-generated water supply pipeline electronic map. Tiny pipeline leakage points can be accurately captured and positioned, and a GIS system of an underground water supply pipe network can be calibrated and automatically constructed; and the labor and equipment cost are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of water supply pipeline leak detection, in particular to a water supply pipeline leak detection system and method based on a flexible pipeline robot. Background technique [0002] At present, the main detection methods for water supply pipe network leakage are: audio-audio leak detection method, DMA partition measurement. [0003] 1) Audio-audio leak detection method: When tap water flows normally at a certain flow rate in the pipeline, it is silent and audible on the ground. However, if there is water leakage in the pipes and auxiliary facilities, the water with a certain pressure will be sprayed out through the damaged part, and it will cause a vibration sound of a certain frequency when it is hit on the earth or stone or punched into a cavity. The audio-audio leak detection method is based on this to distinguish water leakage and determine the leak point. [0004] Advantages: The tools used are simple,...

Problems solved by technology

[0005] Disadvantages: In order to prevent noise interference during the day, leak detection must be carried out at night, which requires high technical skills for workers (master with apprentice mode, long-term experience accumulation), low detection efficiency

[0008] Disadvantages: The cost of establishing a DMA metering management area is relatively high. It not only requires flow meters and data recorders, but also needs to replace or modify valves to meet the closedness of the m
