Problems solved by technology

However, when UHF RFID technology is applied to specific industries, there are various application conditions and requirements, such as: when entering and exiting the warehouse bayonet type RFID reading equipment to read the tags of incoming and outgoing items, due to the different types of tags The quantity is large, the reading distance is inconsistent, and there are other item tags in the warehouse, which will lead to the misreading of other items in the warehouse during the reading process, and then it is impossible to accurately judge the actual label of the item in and out.
At present, this situation is generally dealt with by adjusting the radio frequency power of the antenna, but this method still cannot fundamentally solve the misreading problem

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 A UHF RFID reading system shown includes a control host, an UHF RFID reader, and an RFID antenna; the control host is connected to the UHF RFID reader through an Ethernet interface or a serial port, and is used for The RFID reader exchanges commands and receives the item tag information read by the UHF RFID reader; the UHF RFID reader is also connected to the RFID antenna through a radio frequency feeder to radiate the radio frequency signal and receive the information received by the RFID antenna. The echo signal from the item tag is sensed; the RFID antenna also transmits information with the RFID tag through the electromagnetic wave signal in the electromagnetic field space.

[0022] RFID tags are fixedly set on corresponding items (such as tools and materials) by pasting or binding, and are used to digitize the id...

Abstract

The invention discloses an ultrahigh frequency RFID identification and reading system and a misreading removing method. The identification and reading system comprises a control host, an ultrahigh frequency RFID reader and an RFID antenna. The control host is connected to the ultrahigh frequency RFID reader through an Ethernet interface or a serial port. The ultrahigh frequency RFID reader is connected to the RFID antenna through a radio frequency feed line. The RFID antenna carries out information transmission with an RFID label through an electromagnetic wave signal. The control host is provided with a parameter learning module and a misreading removing module. The misreading removing method comprises a parameter learning process and a misreading removing process. In the invention, accuracy of the ultrahigh frequency RFID reader to identify and read an object label can be greatly increased and a RFID label misreading problem can be solved.

Description

technical field [0001] The invention relates to a system and a method, in particular to an ultra-high frequency RFID reading system and a method for removing misreading thereof. Background technique [0002] With the rapid development of science and technology, RFID (Radio Frequency Identification, radio frequency identification) technology, as an important branch of the Internet of Things technology, is more and more widely used due to its non-contact, long-distance, and simultaneous reading of multiple tags. However, when UHF RFID technology is applied to specific industries, there are various application conditions and requirements, such as: when entering and exiting the warehouse bayonet type RFID reading equipment to read the tags of incoming and outgoing items, due to the different types of tags There are a large number of items, the reading distance is inconsistent, and there are other item tags in the warehouse, which will lead to the misreading of other items in the...
