A RFID tag reading method, system, device and readable storage medium

Abstract

The application relates to an RFID tag reading method, system, device, and readable storage medium. The RFID tag reading method calculates the moving time of the goods passing through the grating according to the time when the goods enter the gate and the time when they leave the gate, and the movement time meets the movement time limit condition Only the cargo information corresponding to the cargo will be recorded, and the cargo information with abnormal movement will be filtered out to ensure the reliability of the cargo trajectory, thereby improving the reliability of RFID tag reading; by limiting the reading time window of RFID tags, it can maximize Guarantee that the RFID reader only reads the latest cargo information to avoid string reading of RFID tags; compares the currently read RFID tags with the RFID tags of unread and read cargo, and filters out unreliable ones. RFID tags to further improve the accuracy of cargo RFID tag reporting.

Description

technical field [0001] The invention belongs to the field of label reading, and in particular relates to an RFID label reading method, system, device and readable storage medium. Background technique [0002] As a non-contact sensing communication technology, RFID technology has been widely used in many fields such as logistics warehousing, cargo management, item tracking, anti-counterfeiting labels, etc., especially in warehousing and logistics applications. [0003] In the existing application of logistics sorting using RFID technology, the RFID tags on the goods are read by the RFID reader to identify the goods, but affected by the surrounding environment of the RFID reader and the RFID tags on the other goods, it is easy to appear In the case of data string reading, that is, the RFID reader reads the RFID tag of the front or rear of the current cargo, but the label of the current cargo is not read, resulting in a mismatch between the read label information and the actual...

AI Technical Summary

Problems solved by technology

Even so, there are still deficiencies in the tag reading method using gratings: the RFID tags of different goods are often not attached to the same position, resulting in cross-reading by the RFID reader when the goods pass through the grating to trigger tag reading

[0005] Therefore, there is still a lack of RFID tag reading methods with higher reading accuracy
