(1) System overview
This system uses RFID technology to assign product electronic tags, identify materials, and automatically record process operations and other information technology methods. It performs error-proofing, monitoring, real-time analysis and tracking functions, and realizes error-proofing and lean production of product production. Greatly improved production efficiency and product quality, and greatly improved customer satisfaction.
Taking products as the main line, using RFID technology as the means, starting from the plan, the material, production process, semi-finished products, and finished products of the product are automatically identified, recorded and monitored, and fully transparent management is implemented to prevent, detect and correct errors in production. , And trace the product afterwards, clearly inquire about the authenticity, whereabouts, storage, process records, producer, quality inspector, and production date of the product, and analyze the reasons for the production of defective products.
Product quality traceability realizes full-process tracking management, which not only strengthens corporate quality management, reduces error correction costs, but also facilitates companies to collect product information to understand consumption trends and improve rapid response capabilities. In the field of process manufacturing, especially in the fields of food safety, pharmaceutical production, and chemical product manufacturing, the establishment of a product quality traceability system has become one of the important management methods for enterprises to survive. In discrete manufacturing companies, such as automobiles and electronic products, when quality problems occur, the traceability system can quickly find out the relevant batches and the key to the quality problems, and recall the relevant batches of products to reduce recall losses.

(3) System topology diagram
Install RFID collection terminals at the key collection points of the production line. The users who feed the materials paste the printed labels on the main parts of the finished product, and then scan the labels. The system also records that the product has been put into production. The Kanban can check the total amount of input. When the product passes through each process of the line, the system will determine whether the previous process has been completed. For wrong operations, missing tools, etc., it directly prompts the error and requires the user to make up the scan. The system records the elapsed time, operator, and shift information of each process so that the production information can be queried according to the label in the future. For the quality inspection process, the system records the repair status of the defective type of the product, according to the reported defective statistical phenomenon distribution, and follow-up quality traceability work.
The function of the production line Kanban is used to display the WIP status of the product, display the input and output quantity, and the quantity of defective products can be refreshed and viewed by the person in charge on duty. Ordinary users can view the production report, quality traceability report, production traceability report, etc. through the enterprise LAN . The system topology diagram is as follows:
(4) Function introduction
①The user can produce the label of the finished product according to the production work order, and then scan the label to trace all the information of the production work order, and start to paste the label on the main part of the finished product through the production line positioning, and perform the positioning scanning work. At this time, the system Record that the work order has been put into production records, and display the information on the kanban and reports. As shown in the figure below, the top 5 rows show the total production quantity of Factory A, and the following shows the respective production status of several production lines of Factory A.
②Data collection points are installed at important stations on the production line. Operators scan their own ID card to log in to the system, and the system records the relevant information of the operator. Scan the product label and select the bad type to upload the data. The operation interface is as shown in the figure below:
③After the user uploads the quality inspection, the system analyzes and summarizes the undesirable phenomena based on the uploaded data, and displays them in the form of charts. The production management staff can monitor the on-site production situation in real time and make real-time adjustments to the process. The following figure shows the distribution of several undesirable phenomena.

(6) Benefit analysis
The introduction of the production traceability management system can quickly improve the information management level of the production line and realize the visualization of production data. The user objectively analyzes the production situation based on the data collected by the production line, and instantly understands the production progress and process capability. Reduce production waiting waste, including unbalanced operations, improper scheduling of operations, waiting for materials; waste of defective products and waste of work in progress caused by poor quality. Thereby reducing the production cost of the enterprise.
The system executes operations strictly in accordance with the order process, and the products must comply with the process flow for operation execution, realize the effective prevention mechanism of pull production, and prevent waste caused by fleeing goods and poor processes. Through RFID technology, this type of accident can be reduced to zero.
Realize the visualization of work order progress, users can view the production order status through LAN, browser, etc., and grasp the quality and delivery date in real time; improve customer satisfaction.
Process personnel and production management personnel can immediately release ECN and schedule production based on the information collected in real time.
according toRFIDThe label can quickly trace product processing time, tooling, operator, quality inspection and other information, so that it is easy to grasp the cause of customer complaints and corresponding solutions in time.
Users can expand system functions according to their own needs, such as adding functional modules such as warehouse management, supply chain logistics management, process management, production execution management, distribution management, production planning, quality management, and equipment KPIs.
