Abstract

Improving leak detection and localization accuracy in urban gas pipeline networks is crucial for ensuring city safety. This paper reviews current leak detection technologies, including sensor technology, acoustic detection methods, and gas concentration monitoring methods, and analyzes their advantages and disadvantages. It proposes a method to enhance localization accuracy through the fusion of multiple sensors and data mining, which has been validated by experiments. The results show that fusion technology can significantly improve the accuracy of leak localization, providing technical support for urban gas safety management.
