[0002] With the progress of society, various measuring instruments have emerged, such as electricity meters and water meters for measuring electricity and water consumption. These measuring instruments have become indispensable measuring tools in life. After these measuring instruments are manufactured, they need to be managed in and out of the warehouse, which in turn creates a demand for identifying measuring instruments.

[0003] For the identification of measuring instruments, RFID scanners are traditionally used to identify the RFID tags on the measuring instruments and obtain their product serial numbers. However, some measuring instruments do not have RFID tags. For these instruments, it is necessary to use a handheld barcode scanner to scan the barcode on the surface of the measuring instrument or to manually record the barcode. This results in low efficiency in the identification of measuring instruments and is prone to errors during operation, such as the RFID scanner identifying other signals or manual recording errors, which in turn affect the quality of the identification of measuring instruments.

[0004] Therefore, how to provide a method, system, equipment, and medium for identifying measuring instruments to improve the efficiency and quality of measuring instrument identification has become an urgent technical problem to be solved. Summary of the Invention

Step S30: The management system identifies the RFID tags of the measuring instruments using an RFID scanner; Step S40: The PLC lowers the intelligent data acquisition shelf through the lifting mechanism and identifies the barcode of the measuring instrument through the wide-angle camera on the intelligent data acquisition shelf. Step S50: After the management system performs mutual verification using RFID tags and barcodes, it binds the RFID tags and barcodes and updates the measuring instrument management table. Step S60: After identification is completed, the PLC raises the intelligent acquisition shelf and the electric roller shutter, and discharges the material frame through the roller conveyor line.

[0009] Further, step S40 specifically includes: Step S41: After the PLC lowers the intelligent acquisition shelf to the preset height through the lifting mechanism, it sends an identification command to the microcontroller. Step S42: Based on the received recognition command, the microcontroller starts the fill light to illuminate the entire material frame, controls the wide-angle camera to autofocus, and then takes a picture of the equipment. Step S43: After the microcontroller performs background removal and noise reduction preprocessing on the appliance photo, it analyzes the appliance photo using a machine learning algorithm to identify the appliance type, scans the barcode carried in the appliance photo, and verifies the format of the barcode based on the appliance type.

The discharge module is used to raise the intelligent acquisition shelf and electric roller shutter after the identification is completed, and discharge the material frame through the roller conveyor line.

[0011] Furthermore, in the metering instrument management table maintenance module, the metering instrument management table includes at least RFID tags, barcodes, identification time, and inventory quantity; the content of the RFID tags and barcodes is the product serial number.
