The location and topology of grounding grid conductors are necessary to corrosion diagnosis and digging in most cases. In this paper, an integrated detecting device for grounding conductor buried position is designed. Based on the principle of magnetic field method, a multi-layer cascade PCB hollow coil sensor is designed. AC excitation current source, 16-channel control circuit, lock-in amplifier (LIA) circuit and 4-channel synchronous acquisition circuit are realized. The experimental test is completed for the integrated detection device, and results verify the feasibility of the system.
