Application of RFID technology products in the manufacturing industry


The RFID electronic tags on the production line use RFID technology to realize automatic control and monitor products on the production line, which greatly improves the speed and accuracy of production, improves work efficiency, improves production methods and saves costs. The RFID tag conveniently and accurately records process information and process operation information to meet flexible production requirements. Using RFID technology to achieve automatic control and monitoring on the production line, improve productivity, improve production methods, and save costs.


I. Analysis of the demand for RFID in the manufacturing industry


Manufacturing production lines consume a lot of materials almost every month, and the production results and expectations are affected by the fact that there are errors, and the production lines often cause various errors due to human factors. By attaching the RFID tag to the production material or product, the production quantity information, specification, quality, time, responsible person and other production information can be automatically recorded instead of the traditional manual recording; the production supervisor can read the product information at any time through the reader; other related The personnel can grasp the production status in time and adjust the production schedule according to the situation; the procurement, production and storage information are consistent and can be monitored in real time; the materials and products will automatically record the warehousing information before leaving the warehouse, and can track the location of the goods in real time.


In the industrial sector, RFID technology is used to assign an identification number (ID) to each component in the product, that is, the name of the component in the information network. Through the RFID technology, the production status and inventory status are mapped to the information network, and registered in the In the field center database, it is transmitted to the information system. Applying RFID technology to production line monitoring enables automatic control and inspection, saving costs. RFID tags can uniquely identify each product, and record the raw materials and sources of each product, production line location, production process and inventory status through the application program, providing an effective basis for enterprises to better manage production and adjust inventory.


Second, the application characteristics of RFID in manufacturing


    2.1 Data sharing in real time


It is very important that the production line feeds back information in a timely and accurate manner during the production process of the manufacturing enterprise. In the past, it was only possible to manually record faults while producing, and to collect and collect information from each process after production was completed, which was time-consuming and laborious, and sometimes could not be very accurate. RFID reading equipment is installed in each process of the production line, and RFID electronic tags that can be read and written repeatedly are placed on the products or trays. In this way, when the product passes through these nodes, the RFID reading and writing device can read the information in the label on the product or the tray, and feedback the information to the back-end management system in real time, so that the manager can know the working status of the production line in time. .


2.2 Standardized production control


The RFID system provides an up-to-date, real-time data stream that is complementary to the manufacturing execution system. The information provided by RFID can be used to ensure the correct use of machinery, tools and components, enabling paperless information transfer and reduced downtime. Furthermore, when raw materials, parts and assemblies pass through the production line, real-time control, modification and even reorganization of the production process can be carried out to ensure the reliability and high quality of production.


2.3 Quality tracking and traceability


In the production line where RFID systems are implemented, product quality is detected by a number of test positions distributed in several locations. It must be possible to express the quality of all previously collected data of the workpiece at the end of production or before product acceptance. This can be done easily with RFID tags, as the quality data obtained throughout the production process has gone down the production line with the product.


  3 Application principle of RFID in production line


At present, bar code-based production management system enables various quality analysis and control to be easily realized, and bar code technology has its advantages and obvious disadvantages, such as being easily contaminated, easily damaged, scanning distance, etc. Inefficient, unable to meet fast and efficient needs. Use RFID tags, barcodes, sensors to collect real-time data from the production line, and transfer the read data to the host device (controller or computer) via the network (wired or wireless). However, to manage loose sensors, you need a brand new The management mechanism of the network can be automatically discovered and organized. The method adopted is to deploy an RFID reader and at the same time establish a network connection of the reader to solve the problem of planning, optimization and control of the reader network. The RFID tag on the item, combined with the RFID reader connected to the network, each recognition means a tracking of the item.
