Tunnel reading and writing device based on rfid technology

Abstract

The invention relates to a tunnel-based read-write device based on the RFID technology. The tunnel-based read-write device based on the RFID technology is characterized in that an RFID detection mechanism facing a conveyor is arranged on the inner side of a shell; the RFID detection mechanism comprises a radio frequency reader-writer and four radio frequency antennas connected with the radio frequency reader-writer; every two radio frequency antennas are in one set; a micro-control chip, a radio frequency signal sending circuit, a radio frequency signal receiving circuit, an antenna control circuit, a power distribution circuit, matching circuits and a phase control circuit are arranged in the radio frequency reader-writer; the micro-control chip is respectively connected with the control signal input ends of the radio frequency signal receiving circuit, the radio frequency signal sending circuit, the antenna control circuit and the phase control circuit; the output end of the radio frequency signal sending circuit is connected with the input end of the power distribution circuit; every path of output of the power distribution circuit is connected with one path of matched circuit; the output ends of the matched circuits are connected with the radio frequency antennas. The tunnel-based read-write device based on the RFID technology has the advantages of being high in reading success rate and detection speed, convenient to move, high in safety performance and the like.

Description

technical field [0001] The invention relates to a production line management system, in particular to a tunnel-type read-write device based on RFID technology capable of realizing production line transmission and fast reading of a large number of tags. Background technique [0002] Traditional production line management is often accomplished by means of barcode labels or manual recording of documents. For example, in the laundry industry, employees will hang or paste a label on each piece of clothing, with a corresponding number on the label, which requires manual registration and inventory. This management method, first, is inefficient, and the speed of manual inventory is quite slow; second, the accuracy rate is low, and the shortcomings of barcode labels such as easy duplication, non-pollution, moisture-proof, and manual recording of documents are prone to clerical errors, which easily lead to errors in product records. The third is to waste a lot of manpower and materia...
