Design and realization of underground pipeline location system based on RFID technology

In this paper, an underground pipeline location system based on RFID technology is presented. The system achieves the underground pipeline location by mutual coupling between ground detector and underground electronic information tag. The system contains a low-frequency RFID modulation and demodulation circuit, which can recognize the tag automatically. The agreement of tag and pipeline information is customized designed to facilitate the identification of the tag, the location of the pipeline and the management of information storage. This system realizes the position marking in the map by GPS and Baidu map static API. The system can also access the remote MySQL database to store and manage the tag information. The experiment results show that the system is convenient and practical for underground pipeline location.
