1. the method can enable different construction units to quickly and accurately know whether the cable exists below the construction position, avoids the occurrence of fault power failure caused by cable damage in construction, and is favorable for reducing the occurrence of fault power failure of the power distribution network.

2. Compared with the original method that construction is required to be carried out before construction, the process is complicated and time-consuming, the method can greatly simplify the process and shorten the time.

3. According to the invention, different prompts can be generated when the cloud storage and processing module feeds back information to other manager terminals according to whether the position information is selected to be confidential or not during uploading, so that key information cannot be leaked, and meanwhile, the construction cannot be damaged.

The present applicant has described and illustrated embodiments of the present invention in detail with reference to the accompanying drawings, but it should be understood by those skilled in the art that the above embodiments are merely preferred embodiments of the present invention, and the detailed description is only for the purpose of helping the reader to better understand the spirit of the present invention, and not for limiting the scope of the present invention, and on the contrary, any improvement or modification made based on the spirit of the present invention should fall within the scope of the present invention.
