Recognition system and recognition method of radio frequency labels

Abstract

The invention discloses a recognition system and a recognition method of radio frequency labels. The system comprises a plurality of radio frequency labels and an information collector. The information collector comprises a control module and transmitting receiving modules in one-to-one correspondence with the plurality of radio frequency labels. Each transmitting receiving module is installed at the placing position of a target object carrying one radio frequency label, and each transmitting receiving module is connected with the control module through a signal wire. The method achieves management of radio frequency label information based on the system. The method includes enabling each transmitting receiving module to carry a unique serial number and enabling the control module to conduct recognition and signal transmission on the transmitting receiving module according to the serial number. The system achieves unique recognition on the radio frequency labels, overcomes disturbance in the label reading process, is simple in structure and reliable in recognition, accurately monitors specific target object information at the specific position, can be widely applied to storage management of objects in markets, supermarkets, logistic warehouses and the like and greatly improves logistic management efficiency.

Description

Technical field [0001] The present invention relates to a system that facilitates the identification of target information by a radio frequency tag, and also relates to a method for identifying the target using the system. Background technique [0002] Radio frequency tag RFID technology uses the reader to send out radio frequency signals to generate a changing magnetic field. After the radio frequency tag enters the magnetic field, it generates an induced current through the coil on the tag, and uses the energy obtained by the induced current to send product information stored in the radio frequency tag chip. , Or actively send a signal of a certain frequency, the reader reads the information and decodes it, and then sends it to the central information system for relevant data processing. [0003] Radio frequency tag technology has been successfully used in large supermarkets, logistics systems, and the Internet of Things. However, the application of existing radio frequency tag ...

Problems solved by technology

[0005] One of the technical problems to be solved by the present invention is to provide a radio frequency tag identification system, which overcomes the defect that the existing radio frequency tag system can only read the information of the radio frequency tag and cannot identify the state of the target object represented by the radio frequency tag

[0006] The second technical problem to be solved by the present invention is to provide a radio frequency tag identification method to overcome the defect that the existing radio frequency tag system can only manage a single tag at the same time and cannot manage multiple densely arranged tags at the same time
