Industrial RFID technology is indispensable for enabling smart manufacturing

A complete RFID system uses RFID technology to automatically identify objects, collect data and transmit data. It is usually composed of computer systems, RFID Readers and RFID electronic tags. Among them, the computer system includes PC or PLC and other controllers, and even the WMS, MES, ERP and other systems at the user's site, which are used to receive information fed back by the RFID reader. The RFID reader is mainly composed of a wireless transceiver module, an antenna, a control module and an interface circuit. It is used to complete the writing and reading operations of information in the RFID electronic tag and is a key data collection terminal in the RFID system. The core components of the RFID electronic tag are the RFID tag antenna and the tag chip, which are the data carriers used to mark the objects to be traced. It records the data information and can read and write with the RFID reader.

In industrial scenarios, there are many field-level devices that need to be connected to the Internet and collect data. However, among all the field equipment, although PLC, robots, automation equipment, etc. can communicate and transmit data with the host system through their own communication interfaces and communication protocols, there are also some objects (such as Tools, workpieces, raw materials, semi-finished or finished products, pallets for loading materials, etc.) that do not have communication capabilities themselves, but they are equally important and even more numerous. In order to enable these objects to communicate with the host system and realize data collection, RFID electronic tags can be marked on these objects or Assets.

In this way, RFID technology can be used for automatic identification and data collection, and these assets can be transformed into smart objects, which can Store and transmit information such as the surrounding environment, storage status, and location to the upper information management system. In this way, enterprises can realize the transparency of production chains and supply chains, and accurately trace them. Then, enterprises can use this information for analysis and mining to make more accurate and scientific decisions.

In the industrial field, RFID technology, as an important data collection technology, is one of the key technologies of intelligent manufacturing and Industry 4.0, and is also the key to improving efficiency, ensuring quality, and realizing intelligent industry. This is because data collection is the basis for realizing intelligent manufacturing and Industry 4.0, and automatic identification is the core technology of data collection. The two together constitute an important bridge to intelligent manufacturing.

The reasons for using RFID technology in the Internet of Things system can be attributed to the following aspects:

1. Automation and efficiency of data collection

RFID technology allows identification and data exchange without direct contact with objects, which greatly improves the efficiency and accuracy of data collection. It can also obtain the identity information, location information and status information of objects in real time to ensure the timeliness and accuracy of data.

2. Enhance the security and traceability of the Internet of Things system

RFID technology can ensure the traceability of the entire chain from production to consumption through real-time data collection. It can also be combined with encryption technology to improve the security of the Internet of Things system. Protect the data in the RFID tag through encryption, prevent data leakage and illegal access, and ensure the stable operation of the Internet of Things system.

3. Promote the intelligent upgrade of the Internet of Things system

The RFID Module is deeply integrated with other technologies in the Internet of Things (such as cloud computing, big data, artificial intelligence, etc.) to jointly promote the intelligent upgrade of the Internet of Things system. Based on the data collected by RFID technology, the Internet of Things system can provide enterprises with more accurate and efficient management decision support.

4. Adapt to complex environments and application scenarios

RFID technology has a wide range of application scenarios in the Internet of Things system, and can work in various harsh environments. For example, in humid, high temperature or low temperature environments, RFID electronic tags can still work normally to ensure stable data transmission.

In the industrial field, the value brought by RFID technology includes: realizing the automation and real-time collection of various production data, making up for the "information gap" between the enterprise planning layer and the control layer, timely grasping the production plan and production line production status, and improving production flexibility; automating the production process while avoiding human errors; managing or reducing inventory; effectively tracking, managing and controlling the resources and work-in-progress required for production, and realizing transparent and visual management of the production process; improving the timeliness and accuracy of material distribution at the production site, and reducing the assembly error rate; strengthening the production process quality monitoring and tracking capabilities, improving product quality and the overall production efficiency of the production line, and at the same time, through the analysis and mining of the collected data, making management decisions more optimized, etc.
