In order to realize the comprehensive and rapid detection of natural gas leakage,the spatial correlation monitoring method of natural gas leakage based on the improved artificial immune algorithm is proposed.Natural gas leakage spatial corre-lation monitoring network is designed to collect gas pipeline upstream and downstream pressure,flow,sound wave and other data of each sensor node.Different intensity levels are assigned to different location sensing network nodes.The advanced net-work node is taken as the standard node,and the adjacent node is determined according to the location weight of each node.The experimental results show that the proposed method can effectively monitor the natural gas pipeline leakage situation,and immediately determine the leakage site,and the average monitoring relative deviation is only 0.12.It can improve the safety in-dex of the natural gas pipeline,and reduce the degree of pipeline damage.
