An electronic tag identification method and system

Abstract

The invention discloses an electronic tag identification method and system, which relate to the field of tag identification. The method includes such steps as: a reading and writing device sends an identification signal; The electronic tag continuously receives an identification signal when the electronic tag enters an identification area of the reading and writing device. The electronic tag changes the state of the electronic tag according to the identification signal, and sends a feedback signal when the electronic tag is in the first state. When the read / write device receives the feedback signal, the read / write device identifies the feedback signal. The invention reduces the possibility of the electronic tag recognition failure of the reading and writing device, and increases the recognition accuracy of the reading and writing device.

Description

technical field [0001] The invention relates to the field of label identification, in particular to an electronic label identification method and system. Background technique [0002] The hotel has become one of the common buildings. The linen in the hotel, as the property of the hotel, also needs to be strictly managed. The traditional linen management of the hotel usually uses manual inventory. The linen management process is complicated and tedious, and it is easy to make mistakes. With the development of the Internet of Things technology, the Internet of Things technology is applied to linen management. By sewing RFID tags on the linen and reading the linen through a reader with an antenna, the linen management can be realized. The management process of linen is relatively simple and efficient, which is beneficial to the hotel's management of linen. [0003] In actual use, it will be found that during the linen scanning process, the RFID tag on a single linen will provi...

AI Technical Summary

Problems solved by technology

[0003] In actual use, it will be found that during the linen scanning process, the RFID tag on a single linen will provide a large number of signals for the reader to read, and because the hotel has a lot of linen, the reader will read The signals sent by a very large number of RFID tags increase the time for the reader to read the RFID tag and reduce the recognition efficiency of the reader

[0004] At the same time, when the reader reads an RFID tag, there are still a large number of signals sent by other RFID tags in the reader, which reduces the possibility of the reader identifying the RFID tag that needs to be read, and then causes the reader to be confused. The possibility of RFID tag recognition failure reduces the reader's recognition accuracy of RFID tags
