| Abstract: | The hardware and software solutions to detecting of gas pipeline leaks were established.Basing on the sonic wave and hydromechanics theory,the formation,features and acquisition methods of infrasonic wave were researched;the algorithm of sonic wave speed in gas pipelines was improved,and the time shift between first and last stations was obtained by making use of GPS module to locate the leak. |
