Description
Technical Field
The invention relates to a production line management method, and belongs to the technical field of signal detection.
Background
In the manufacturing industry, in order to improve the production efficiency and the product quality, a production line is adopted for large-scale batch production operation. In order to detect the quality of the product, the product information on the production line needs to be collected.
The product information reading of the existing production line is to apply a Radio-Frequency Identification (RFID) technology, install RFID reading devices on each node of the production line, place RFID electronic tags capable of being read and written repeatedly on products or trays, and when the products or trays pass through the nodes, the RFID reading devices can read the information in the tags on the products or trays.
The RFID needs to read qualified information of a previous station, write production data of the station and write the qualified information of the station in each workstation, that is, three times of reading and writing are needed in each workstation.
And the average service life of each RFID is read and written ten thousand times, so the service life of the RFID can be greatly shortened by adopting a management mode in the existing production line, and the maintenance cost of an enterprise on products is increased. In addition, the RFID has limited data bearing capacity, and is not suitable for products with more production data.
Disclosure of Invention
The invention aims to solve the problems that the service life of an RFID (radio frequency identification device) is shortened due to the fact that the RFID technology is adopted for detecting and managing products by the existing production line, the number of times of reading and writing is large, and the product is not suitable for products with large production data, and provides a production line management method based on a Kpageware OPC (optical proximity correction) communication protocol.
The invention relates to a production line management method based on a Kpseware OPC communication protocol, which comprises the following specific processes:
s1, arranging a correlation sensor at a workstation of the production line, detecting a tray signal through the correlation sensor, and executing S2 when a tray exists;
s2, detecting whether a product is on the tray or not through the correlation sensor, and executing S3 when the product is on the tray;
s3, reading the RFID electronic tags on the products by FRID recognition equipment arranged on the workstation, and recognizing the RFID information in the RFID electronic tags;
s4, the PLC receives the RFID information through the serial communication interface and sends the RFID information to the server through a Kpageware OPC communication protocol;
s5, the server inquires whether the product is qualified in the previous work station according to the RFID information, and feeds back the production information of the previous work station to the PLC; the PLC judges whether the production information of the previous work station of the product is qualified, if not, the current work station does not operate, and if so, S6 is executed;
s6, the PLC uploads the production data of the current workstation to the server, and the server feeds back a successful upload signal of the production data of the current workstation after receiving the production data of the current workstation;
s7, the PLC judges whether the production information of the current workstation is qualified or not, the qualified information of the current workstation is uploaded to the server, and the server feeds back a successful uploading signal of the qualified information of the current workstation after receiving the qualified information of the current workstation, so that the information of the current workstation is acquired.
Preferably, the RFID reading device in S3 reads the RFID tag on the product, and when the RFID information in the RFID tag is identified, the RFID reading device determines whether the reading of the RFID information is successful, if so, S4 is executed, otherwise, the number of times of reading of the RFID information is determined, if the number of times of reading is less than 15, S3 is repeatedly executed, and if the number of times of reading is equal to 15, the information that the current workstation is unqualified is uploaded to the server.
Preferably, the RFID information S3 includes an RFID number and a product unique code.
Preferably, the RFID information is sent to the server in the form of a query signal via Kpeware OPC protocol as described in S4.
Preferably, when the server in S5 feeds back the production information of the previous workstation to the PLC, the PLC determines whether the production information of the previous workstation is received, if so, the PLC continues to execute S5 to determine whether the production information of the previous workstation of the product is qualified, otherwise, the PLC determines the number of times of reading, if the number of times of reading is less than 15, the PLC returns to execute S4, and if the number of times of reading is equal to 15, the information that the current workstation is unqualified is uploaded to the server.
Preferably, when the server feeds back a successful uploading signal of the production data of the current workstation in S6, the PLC determines whether the successful uploading signal of the production data fed back by the server is received, if yes, S7 is executed, otherwise, the PLC determines the number of reading times, if the number of reading times is less than 3, S6 is repeatedly executed, and if the number of reading times is equal to 3, the unqualified information of the current workstation is uploaded to the server.
Preferably, when the server feeds back a signal indicating that the uploading of the qualified information of the current workstation is successful, the PLC determines whether the signal indicating that the uploading of the qualified information fed back by the server is successful is received, and if the signal is successful, the acquisition of the information of the current workstation is completed, otherwise, the PLC determines the number of reading times, and if the number of reading times is less than 15, the PLC repeatedly executes S7, and if the number of reading times is equal to 15, the information of the current workstation which is not qualified is uploaded to the server.
The invention has the advantages that: according to the production line management method based on the Kpseware OPC communication protocol, RFID information is read once at each workstation, and then communication is carried out with the server through the Kpseware OPC communication protocol, so that the RFID reading and writing times are reduced by two thirds, and the service life of RFID can be prolonged by 200%. In addition, the production line management method is to directly upload the production information to the server without writing the production information into the RFID, and can avoid data loss caused by limited bearing data for products with more production data.
