As enterprises continue to expand and their businesses become increasingly complex, asset management becomes increasingly important. Traditional asset management methods suffer from low efficiency and poor accuracy. RFID technology can achieve real-time tracking and monitoring of assets, improve data accuracy and management efficiency. The key to the efficient management of a large number of assets by RFID systems lies in the design of anti-collision algorithms within the reader/writer. In order to solve the multi-tag collision problem, we designed a new RFID anti-collision algorithm. We proposed the MBQ-DR (Multi Bit Mapping Query-Dual Response) QT protocol with the idea of efficiently reducing redundant queries and efficiently handling single-bit collisions. This protocol uses multi-bit mapping queries to completely eliminate idle time slots, and uses a dynamic query update mechanism to effectively reduce redundant queries, improve system efficiency, and reduce communication load. The dual response mechanism is introduced to further reduce the total number of queries, further improve system efficiency, and shorten the total recognition time.
