The manual paper registration method used in the traditional equipment use management has been unable to adapt to the current huge number of equipment and the rapid development of electronic information control technology. How to realize remote tracking control of equipment has become the current research hotspot. Therefore, the basic working principle of RFID technology is analyzed, and the equipment location management system based on RFID is established. First of all, the overall technical scheme of the system is finalized, and the selection requirements of the system microcontroller, RF transceiver module and other important hardware circuits, as well as the selection of communication protocol, reader and tag and other software design schemes are described in detail. Then, the LANDMARC algorithm is used to obtain the stable and reliable received signal, so as to accurately locate the label position. Finally, in the practical application environment, the maximum communication distance, sensitivity and positioning accuracy of RFID based equipment positioning technology are tested. The experimental results show that the equipment positioning management method proposed can achieve high-precision positioning control of equipment in a certain range of space, which has a strong guiding significance for practical engineering applications.
