Article: Water leakage detection and localisation based on GCC-PHAT algorithm Journal: International Journal of Wireless and Mobile Computing (IJWMC) 2020 Vol.19 No.1 pp.55 - 61 Abstract: Detection and localisation of pipeline leakage is an effective measure to save water resources. Generalised cross-correlation algorithm is widely used in leak detection. In this paper, by comparing the weighted algorithms of generalised cross-correlation functions, the GCC-PHAT algorithm is used to design a leak detection and positioning system, and relevant experiments are carried out. Multiple sensors are used (including flowmeters, pressure gauges and vibration sensors) to detect leaks and obtain relevant data in the experiment and locate the leak point through the GCC-PHAT algorithm. It is found that the method has better positioning performance through experiments. Inderscience Publishers - linking academia, business and industry through research
