Embodiment Construction

[0014] In order to adapt to different antennas or multi-antennas and can be used in complex environments, the RFID multi-antenna reader-writer in the present invention can separate the antennas, and complete multiple antennas or antenna arrays through fixed digital signal output lines and radio frequency output lines control, so that multiple antennas work according to the established law. Therefore, the RFID multi-antenna reader-writer of the present invention is a novel RFID intelligent reader-writer after the antenna is separated, and the RFID reader (reader-writer) communicates wirelessly with the electronic tag through the antenna, and can realize the reading of the tag identification code and memory data. output or write operation.

[0015] The RFID multi-antenna reader / writer of the present invention is mainly composed of a central controller module, a radio frequency read / write module, an antenna (antenna array) control module, a display module, and a communication int...

Abstract

The invention discloses an RFID multi-antenna reader-writer which comprises a central controller module, a radio frequency read-write module, an antenna control module or an antenna array control module, a display module and a communication interface module. The RFID multi-antenna reader-writer can be used for solving the problem that the single antennae can only be used in the existing reader writer and cannot be separated because of being bounded by the reader writer, is wide in working temperature range, strong in anti-interference capability and rapid in data transmission speed and can reliably operate in a complex condition.

Description

technical field [0001] The invention is a high-frequency RFID electronic tag reading and writing device, and the specific realization technology mainly utilizes RFID automatic identification technology, embedded technology, wireless communication technology and the like. Background technique [0002] RFID (Radio Frequency Identification, radio frequency identification) technology is a non-contact automatic identification technology realized by radio frequency wireless communication. Its basic principle is to use the transmission characteristics of radio frequency signal or space coupling (inductive or electromagnetic coupling) to automatically identify the target object And get relevant data without human intervention. According to different operating frequencies, RFID can be divided into low frequency (LF), high frequency (HF), ultra high frequency (UHF) and microwave frequency band (MW). Depending on the operating frequency, the recognition distance is also different. ...
