Abstract In the management and maintenance of underground cables and urban planning and reconstruction, it is required to quickly and accurately find out the location and depth of underground cables and make clear the cable location information. This paper studies design of urban underground cable path detection system with electromagnetic method as the main theoretical basis to establish cable space equivalent model, innovation point lies in the using field frequency transmission signal transmission, the extremum method in Matlab software, simulation analysis is able to accurately detect the coil magnetic field around the size and direction of change, to formula is derived using the method of double coil cable buried depth. In terms of the implementation of software and hardware of the system, Keil software algorithm is introduced into the ARM control module for output, which can visually and clearly present the path track and buried depth of underground cables, and further improve the degree of intelligence.
