An RFID water meter verification and data writing device and writing method

Abstract

The invention discloses an RFID water meter verification and data writing device and a writing method. The device includes a water meter verification platform, a detection mechanism, a mobile device, and an industrial computer. The device helps the detection structure to step and move directly above each RFID water meter. The detection structure is equipped with a camera and an RFID read-write device. The camera obtains the image information of the dial flow data, and the RFID read-write device reads the unique identification code of the RFID water meter and its position The flow error is written into the label of the RFID water meter, and the industrial computer has the functions of controlling the movement and positioning of the detection structure, reading and writing of the RFID reading and writing device, and image processing. The invention uses a single camera to verify the flow error and at the same time uses an RFID read-write device to write data into the RFID tag placed in the water meter, so as to realize the offline query of the flow error of the water meter at any time during the whole life cycle.

Description

technical field [0001] The invention relates to the field of water meter production, in particular to an RFID water meter verification and data writing device and writing method. Background technique [0002] According to national regulations, water meters used for trade settlement (that is, used to calculate water consumption to collect water fees) within the city must be subject to mandatory verification according to regulations, and can only be put into use after passing the test. With the shortage of water resources, more and more attention has been paid to the accurate measurement of tap water. [0003] At present, some manufacturers use machine vision technology to read the readings of water meters through fixed cameras. After the verification is completed, a paper record card is generally used to record the flow error of each water meter, and these data are usually archived in the water meter factory. There are also some water meter manufacturers who use QR codes or...

AI Technical Summary

Problems solved by technology

There are also some water meter manufacturers who use QR codes or barcodes to mark the flow error information of water meters, but paper barcodes are easily damaged in an environment close to water, and the query equipment needs to be fully connected to the Internet

In this way, whether it is a water plant or an ordinary user, it is very difficult to check the flow error of the water meter.
