Production line management method based on Kpeware OPC communication protocol

The invention discloses a production line management method based on a Kpeware OPC communication protocol, belongs to the technical field of signal detection, and aims at solving the problems that theRFID technology is adopted for product detection management of an existing production line, the read-write frequency is high, the RFID service life is shortened, and the production line management method is not suitable for products with more production data. According to the production line management method based on the Kpeware OPC communication protocol, an RFID electronic tag on a product isread by adopting an FRID reading device arranged on a workstation, and RFID information is identified; the PLC sends the RFID information to a server through a Kpeware OPC communication protocol; theserver inquires whether the product is qualified or not in the previous workstation, if not, the current workstation does not operate, and if yes, whether the production information of the current workstation is qualified or no
