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.

The invention discloses a RFID water meter detecting and data writing-in device and method. The device comprises a water meter detecting platform, a detection mechanism, a moving device and an industrial personal computer, the water meter detecting platform enables water flow with specified pressure and volume to flow through RFID water meters, the moving device helps the detection mechanism to move right above each RFID water meter in a stepped manner, a camera and a RFID reading-writing device are carried on the detection mechanism, the camera acquires image information of meter disc flow data, the RFID reading-writing device reads unique identity code and position of each RFID water meter and writes flow errors into a tag of the corresponding RFID water meter, and the industrial personal computer has functions of controlling moving and positioning of the detection mechanism and reading and writing of the RFID reading-writing device and image processing. One camera is used to detectflow errors, the RFID reading-writing device is used to write the data into the RFID tag arranged in the water meter, and offline inquiry of the flow errors of the water meter at any time within the full life circle is realized.
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...
