Positioning monitoring system and method based on RFID tag

Abstract

The invention provides a positioning monitoring system and method based on an RFID tag. The positioning monitoring system comprises a positioning device body and the RFID tag. Each electronic device needing to be put on a shelf is fixedly provided with the unique RFID tag, and the RFID tag is a passive RFID electronic tag. The positioning device body comprises a control module, a first RFID read-write module, a second RFID read-write module, a first analog switch, a second analog switch and n antenna modules. The system has the advantages that (1) the multiplexing of the RFID read-write modules is realized through the time-sharing access of an antenna module, the number of the RFID read-write modules is reduced, and the cost is reduced; and (2) through the mutual backup and circuit redundancy of the two RFID read-write modules, the working reliability of the positioning device is improved; and (3) through the time-sharing work of the two RFID read-write modules, the service life of a component is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electronic radio frequency identification, and in particular relates to a positioning monitoring system and method based on RFID tags. Background technique [0002] With the rapid development of information technology and communication technology, electronic equipment is widely used in various industries, and various electronic equipment needs to be stationed in cabinets in computer rooms in large quantities. Among them, electronic equipment includes but is not limited to servers. At the same time, for old electronic equipment, it needs to be removed from the rack above the cabinet in time for new electronic equipment to be installed on the rack. For the management personnel in the equipment room, it is necessary to monitor and record the status of the racks being put on and off the racks. [0003] In the prior art, in order to realize the monitoring of electronic equipment on and off the shelf, the foll...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned method for monitoring electronic equipment on and off shelves has the following problems: since there are a large number of installation positions for electronic equipment in the cabinet, multiple sets of RFID read-write modules and antenna modules need to be arranged, which has the problems of complex structure, waste of resources and high cost. Realize the need for low-cost monitoring
