The principle of Radio Frequency Identification (RFID) is non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. RFID applications are very wide, typical applications are supply chain management, personnel management, inventory management, asset tracking, parking lot control, production line automation, material management and so on.

Radio frequency identification technology through radio waves do not contact rapid information exchange and storage technology, through wireless communication combined with data access technology, and then connected to the database system, to achieve non-contact two-way communication, so as to achieve the purpose of identification, for data exchange, series up an extremely complex system. In the identification system, the reading, writing and communication of the electronic tag are realized by electromagnetic wave. According to the communication distance, it can be divided into near field and far field, so the data exchange mode between the read/write device and the electronic tag is also correspondingly divided into load modulation and backscatter modulation.

The basic composition of RFID system includes RFID electronic tag, reader and application software, which is an automatic identification system using radio frequency identification technology for data acquisition and transmission.

Under normal circumstances, after the RFID electronic tag enters the electromagnetic field emitted by the reader, the induced current obtained from the antenna is converted into the power supply of the chip through the booster circuit. At the same time, the energy obtained by the induced current is converted into a digital signal through the RF front-end circuit and sent to the logic control circuit for processing. The information that needs to be returned is sent out from the label memory. The logic control circuit sends it back to the RF front end circuit, and finally sends it back to the reader through the antenna.

🔺1. RFID

RFID electronic tag is a data carrier that is used for item identification, has information storage mechanism, can receive the electromagnetic field modulation signal of the reader and return the response signal, usually known as electronic tag, is the hardware body of the RFID system together with the reader, the core component of RFID electronic tag is the tag antenna and tag chip. From the manufacturing process point of view, the complete process of RFID electronic tags includes chip supply, antenna manufacturing, primary packaging (forming Inlay), secondary packaging (composite), and post-channel printing.

🔺2. RFID reader

RFID reader can realize the reading and writing operation of electronic tag information. RFID readers can be divided into low frequency, high frequency, ultra-high frequency and other different reader products according to the working frequency, and the corresponding frequency band RFID tags are used together. According to the integration mode of read and write module and antenna, it is divided into integrated reader (integrated package of read and write module and antenna) and split reader (separate package of read and write module and antenna, connected by coaxial cable). At present, the most commonly used reader classification on the market is divided into fixed readers and handheld readers according to the portability of use. Fixed reader includes gateway reader, card issuer, cabinet, etc.; Hand-held readers include hand-held machines, wearable readers and so on.

Solution Overview

🔺Material and process management in production line

Many subsectors require traceability data in the process of product production to understand what processes the product has gone through in the production process. Based on such needs, an RFID reader needs to be added to each process, and an RFID tag is placed in each process to track it, usually managing the pallets or vehicles of transport accessories.

🔺Warehouse management of production line

It mainly manages the raw materials of industrial production and the inventory of products, adds RFID tags to the turnover basket or attaches RFID tags to the products, so that the items become iot items that can be traced and their information can be obtained at any time. Turnover basket will generally be recycled or scrapped after many times of turnover, in fact, the cost of a label after many times of use is very low. Under the premise of cost control and efficiency maximization, real-time automatic inventory, fast finding of goods, maximize the use of warehouse space, greatly improve the efficiency of warehousing operations and management level.

🔺Lean management of production feed

The RFID system collects the data of each link on the production line in real time, such as the consumption speed of raw materials and the completion of production tasks. Managers can grasp the production schedule in real time, adjust the production plan in time, and avoid the shutdown caused by material shortage or production delay. On the other hand, traditional material recording and management rely on manual operation, prone to data entry errors or omissions, the use of RFID technology can achieve automatic collection and update of material information, greatly reducing the workload of manual operation and error rate.

Project application value

LINKWIN provides customized software for customers to apply to the whole supply chain. With integrated RFID tags, hardware and software platforms, Linkwin ensures that when materials are transferred from factories, different DCS and channels, traceability information can be queried at any link, enabling customers to reduce the cost of production and circulation links, improve inventory accuracy, and strengthen channel compliance management.

RFID technology through improving data collection efficiency, enhancing inventory accuracy, optimizing inventory turnover, reducing management costs, realizing accurate warehouse location management, improving inbound and outbound storage efficiency, enhancing cargo tracking capabilities, realizing information sharing and collaboration, real-time material tracking, improving production efficiency, quality control optimization and dynamic scheduling adjustment, and other applications. It has significantly improved the purchasing, selling and inventory management of materials, warehouse management of storage locations and lean management of production and feeding materials, bringing significant economic benefits and competitive advantages to the enterprise.
