AI Technical Summary

Technical Problem

When using ultra-high frequency RFID tags to manage paper files, the long reading and writing distances cause interference with the reading of tags, and the location of specific tags cannot be accurately positioned, affecting the efficiency of inbound, outbound and inventory.

Method used

The archive fast entry and exit system based on the ultra-high frequency RFID recognition filtering algorithm is adopted. Through the cooperation of the intelligent cabinet and management terminal, multi-layer warehouse grids and multiple ultra-high frequency RFID antennas are used, combined with the first, second and third-level filter modules, duplicate tags and interference tags are removed to ensure accurate identification of target tags.

Benefits of technology

It realizes efficient and accurate file entry, outbound and inventory, reduces human intervention, improves operational efficiency, and avoids the problem of abnormal data updates.

Abstract

The present invention discloses a fast file entry and exit system and method based on an ultra-high frequency RFID identification and filtering algorithm, comprising an intelligent cabinet, a management terminal, a card reading device, an ultra-high frequency RFID antenna, and an induction device. The present invention is based on an ultra-high frequency RFID identification and filtering algorithm, and uses the signal strength RSSI value of the ultra-high frequency RFID tag to filter data, and can determine the accurate ultra-high frequency RFID tag value. During the entry operation, the entry operation can be completed by simply inserting the file to be entered into the positioning socket of any induction device, and the exit operation can be completed by simply pulling out the file to be exited from the positioning socket of the induction device. In this way, there is no need to use an external RFID identification device for entry and exit, which is time-saving and efficient.
