Positioning method and system for pipeline leakage detection

The invention discloses a positioning method and system for pipeline leakage detection. The positioning method comprises the steps that a lower computer module receives a diagnosis instruction of a cloud server; the lower computer module synchronizes the acceleration acquisition module by using the satellite positioning module; using the synchronized acceleration acquisition module to acquire an acceleration signal according to an acquisition frequency in a preset range; uploading the acceleration signal to a cloud server by using a communication module; the cloud server obtains a cross-correlation map of the acceleration signals collected at the two ends of the target pipe section; and positioning a leakage position on the target pipe section by using the cross-correlation map. According to the positioning method and system for pipeline leakage detection, pipeline leakage can be rapidly and efficiently detected, the specific position of the leakage point on the pipeline can be accurately positioned, the posi
