Application solutions of RFID technology products in manufacturing industry

It has been more than 40 years since the reform and opening up in 1978. my country's manufacturing industry has developed rapidly. As a world power, it needs a strong, independent and autonomous manufacturing industry from the perspective of improving national living standards, economic development, and national security. The emergence of the new industrial revolution is not only a challenge, but also a rare opportunity. Our country has entered the late stage of industrialization and is in a critical period of economic structural transformation and upgrading. The new industrial revolution has promoted a large number of new technologies, new industries, and new models, laying a technical and economic foundation for my country's industrial development and clarifying the future development direction. It has also provided a scientific basis for my country to formulate industrial development strategies, accelerate economic transformation and upgrading, and master development. Initiative provides important opportunities. Let's learn about the application of RFID technology in the manufacturing industry.

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. RFID tags conveniently and accurately record process information and process operation information to meet the needs of flexible production. Use RFID technology to realize automatic control and monitoring on the production line, increase productivity, improve production methods, and save costs.

1. Demand analysis of RFID in manufacturing industry

Manufacturing production lines consume a large amount of materials almost every month, and production results often differ from expectations, affecting delivery. Production lines often cause various errors due to human factors. Attaching RFID tags to production materials or products can automatically record production information such as product quantity, specifications, quality, time, person in charge, etc., replacing traditional manual recording; production supervisors can read product information at any time through readers and writers; other related Personnel can grasp the production status in a timely manner and adjust production arrangements according to the situation; procurement, production, and warehousing information are consistent and can be monitored in real time; the system will automatically record the incoming and outgoing information of materials and products before they leave the warehouse, and can track the location of items in real time.

In the industrial process, RFID technology is used to assign an identification number (ID) to each work-in-progress component, which is the name of the component in the information network. Through RFID technology, the production status and inventory status are mapped to the information network and registered in the information network. In the on-site central database, it is transmitted to the information system. Applying RFID technology to production line monitoring can achieve automatic control and detection and save costs. RFID tags can uniquely identify each product and record information such as the raw materials and source, production line location, production process and inventory status of each product through the application, providing an effective basis for enterprises to better manage production and adjust inventory.

2. Application characteristics of RFID in manufacturing industry

2.1 Real-time data sharing

In the production process of manufacturing enterprises, it is very important for the production line to provide timely and accurate feedback information. In the past, faults could only be recorded manually during production. After production was completed, the information from each process was statistically summarized, which was time-consuming and labor-intensive, and sometimes could not be very accurate. Install RFID reading equipment in each process of the production line, and place RFID electronic tags that can be read and written repeatedly on products or pallets. 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 pallet, and feed this information back to the background management system in real time, so that managers can understand the working status of the production line in a timely manner. .

2.2 Standardized production control

The RFID system can provide continuously updated real-time data streams and complement the manufacturing execution system. The information provided by RFID can be used to ensure the correct use of machinery, equipment, Tools and parts, thereby achieving paperless information transmission and reducing downtime for materials. Furthermore, when raw materials, parts and assemblies pass through the production line, the production process can be controlled, modified or even reorganized in real time to ensure production reliability and high quality.

2.3 Quality tracking and traceability

In the production line where the RFID system is implemented, product quality is detected by some testing positions distributed in several places. All previously collected data on the workpiece must be able to clearly express its quality at the end of production or before product acceptance. This can be easily done using RFID electronic tags, because the quality data obtained during the entire production process has already walked down the production line with the product.

3. Application principles of RFID in production lines

The current production management system based on barcodes allows various quality analysis and control to be easily realized. While barcode technology has its advantages, it also has its obvious shortcomings, such as easy contamination, easy damage, short scanning distance, etc., and batch reading. The efficiency is not high and cannot meet the needs of fast and efficient. RFID tags, barcodes, and sensors are used to collect real-time data on the production line, and the read data is transmitted to the upper device (controller or computer) through the network (wired or wireless). However, to manage loose sensors requires a new, The management mechanism of the network can be automatically discovered and organized. The method adopted is to deploy RFID Readers and writers and establish reader network connections at the same time to solve the planning, optimization and control problems of the reader network. The RFID tags on the items, combined with the RFID readers and writers connected into the network, each identification means a tracking of the items.
