Radio frequency recognition system for identifying objects

Abstract

The invention discloses a radio frequency identification (RFID) system used for identifying objects. The RFID system at least comprises an RFID card and a recognizer, wherein, a first control circuit and a first wire coil are arranged in the RFID card; a second control circuit and a second wire coil are arranged in the recognizer; the second control circuit is connected with an external actuator through a control bus; the first end of the first wire coil is connected with a first wired connecting part; the first end of the second wire coil is connected with a second wired connecting part; theother end of the first wire coil is connected with a third wired connecting part; and the third wired connecting part is connected with a conductor. The invention has the advantages that the communication between the recognizer and the RFID card is realized through the first wired connecting part, the second wired connecting part, the third wired connecting part and the conductor; electromagneticwaves are not required for media transmission during communication process; because the communication is realized through wired connection, the impacts from other electromagnetic waves for the communication are weaken, and the anti-interference ability is enhanced during communication process.

Description

technical field [0001] The invention relates to an identification technology, in particular to a radio frequency identification system for identifying objects. Background technique [0002] Radio Frequency Identification (RFID, Radio Frequency Identification) is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. [0003] The basic RFID system includes a tag (Tag) and a reader (Reader). The tag is mainly composed of a coupling element and a radio frequency chip. Each tag has a unique electronic code. When using a tag, it only needs to be attached to the object to identify it. Target objects, tags are usually called radio frequency identification cards; readers are used to read the information in each tag connected to it, and readers can sometimes write information, whic...

AI Technical Summary

Problems solved by technology

Therefore, the traditional application of the RFID basic system is related to the spatial distance between the tag and the reader, and more importantly, there must be an electromagnetic wave channel to enable the tag to communicate with the reader, and the radio frequency signals they send are easily affected by other Interference from strong electromagnetic waves
