The positional relationship between the installation position and the leakage point of the receiver, according to the geographic spatial information of the water supply pipe, the depth information of each water supply pipe and the location, direction of the sessile receiver are between the mounting position and the leakage point. The location relationship is combined with the depth information of the water supply pipe and the location, and the direction of the direction of the leakage point can be accurately positioned, and the depth and direction of the leakage point are determined, so that the maintenance personnel are maintenance operation, which greatly reduces the work of staff In addition, it is also possible to prevent damage to the water supply pipe during excavation.
