A method for verifying and controlling the consistency of environmental protection levels during the production process includes: Step 1: An environmental engineer determines the environmental protection level of materials and customer projects and records it in the MES system, generating a QR code with embedded data including the environmental protection level of the materials, and attaching a production process flow sheet containing the QR code to the materials; Step 2: During the material cutting and feeding process, a scanning device scans the QR code attached to the materials. The MES system determines whether the environmental protection level of the materials embedded in the QR code is consistent with the environmental protection level of the customer projects recorded in the MES system. If they are consistent, the MES system allows the material cutting operation to begin; Step 3: During the finished product shipping process, a scanning device scans the QR code affixed to the finished products. The MES system determines whether the environmental protection level embedded in the QR code is consistent with the environmental protection level of the customer projects recorded in the MES system. If they are consistent, the MES system allows the finished product shipping operation to begin. This invention improves production quality stability, increases production efficiency, reduces manpower input, and saves time.
