rfid outbound metering device

Abstract

The invention relates to the technical field of RFID, in particular to a novel RFID ex-warehouse metering device. The novel RFID ex-warehouse metering device is characterized in that an RFID reader-writer and at least two radio frequency antennas are arranged in a radio frequency unit, a micro-control chip, a radio frequency signal transmitting circuit, a radio frequency signal receiving circuit, a communication circuit, a multichannel radio frequency output switch control circuit and matching circuits are arranged in the RFID reader-writer, the micro-control chip is connected with the control signal input end of the radio frequency signal transmitting circuit, the control signal input end of the radio frequency signal receiving circuit and the control signal input end of the multichannel radio frequency output switch control circuit, the radio frequency signal transmitting circuit and the radio frequency signal receiving circuit are connected with the multichannel radio frequency output switch control circuit, the multichannel radio frequency output switch control circuit is provided with one input end and two or more output ends, and each output end is connected with the corresponding radio frequency antenna through the corresponding matching circuit. The novel RFID ex-warehouse metering device has the remarkable advantages of being small in size, low in cost, high in read-write speed, accurate in monitoring and the like.

Description

technical field [0001] The invention relates to the technical field of RFID identification, in particular to an RFID delivery metering device with a reasonable structure, convenient use, and the ability to read and write a large number of RFID tags used to mark delivery products in a rapid and accurate manner. Background technique [0002] The barcode label scales used in supermarkets or restaurants at this stage are a combination of ordinary electronic scales and barcode printing technology. It adds a barcode printing unit to the ordinary electronic scales. Related parameters, and then stick the label paper on the surface of the product. When the marked product is sold or out of the warehouse, the relevant parameters carried on the label paper are read by scanning equipment such as a barcode scanner, and the sale is completed. In the actual application process, this type of barcode label weighing equipment has a high cost and a large volume due to the addition of a printing...

AI Technical Summary

Problems solved by technology

In the actual application process, this type of barcode label weighing equipment has a high cost and a large volume due to the addition of a printing unit, and the process of marking the product is to generate label paper and stick the label paper on the product is different from the process of reading out of the warehouse. The process of taking the label paper is independent of each other, and needs to be realized by two sets of equipment respectively, and the operation is complicated

[0003] With the development of RFID identification technology, the use of radio frequency tags to monitor goods for sale has been applied. However, in the existing RFID tag applications, the rate of missed reading for multiple overlapping radio frequency tags and small tags is high, which cannot meet the requirements. Requirements for large-scale applications
