Abstract

The invention provides an RFID reading device with intelligently changed transmitting frequency. The RFID reading device comprises a controller, a frequency converter and a frequency combiner; the input end of the controller is connected with a frequency generator in the reading device; the output end of the controller is connected with a frequency converter, the output end of the frequency converter is connected with a frequency combiner, the input end of the frequency combiner is further connected with a pairing control circuit and an awakening circuit, the output end of the frequency combiner is connected with a transceiver, an antenna is installed on the transceiver, and a plurality of sets of frequency generating circuits are arranged on a frequency generator. According to the invention, a plurality of radio frequency circuits are arranged in the same reader; and the radio frequency circuit can be used for sending out receiving signals with different frequencies, so that the RFIDtag in the area can be quickly identified, the reader equipment is more intelligent and changeable, the application range of the reader is expanded, the industry limitation that one card is used for one purpose is improved, and the leading position of the reader in the RFID industry is accelerated.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to an RFID reading device with intelligently changing transmission frequency. Background technique [0002] Radio Frequency Identification (RFID) is the abbreviation of Radio Frequency Identification. Its principle is to conduct non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. RFID is widely used, and typical applications include animal chip and car chip anti-theft Devices, access control, parking lot control, production line automation, material management. Radio frequency identification technology uses radio waves to exchange and store information without contact, combines data access technology with wireless communication, and then connects to the database system to achieve non-contact two-way communication, thereby achieving the purpose of identification and used for data exchange. An extremel...
