- Abstract:
- With the continuous decrease of data monitoring cost and wide application of pipe network model, the detection and location technology of pipe burst based on data and model has been widely concerned. However, background noise often leads to the failure of the above methods to accurately locate the pipe burst. In order to solve this problem, a burst pipe location method of water supply pipe network based on coupling statistics and model driven was proposed. Firstly, the burst pipe residual of water supply pipe network under delay state was calculated by using weighted least square method, and then the coupling statistical algorithm was used to carry out Kalman filtering and cumulative sum operation on the residual signal of the pipe burst to locate the pipe burst sites. The basic principle and calculation steps of the coupling statistical algorithm were illustrated by using the simplified pipe network, and the feasibility of the algorithm was further verified by using a pipe network in a park. The proposed method could identify and amplify the burst signal from the background noise, reduce the false alarm rate of the burst location, and simultaneously warn and locate the burst sites.
