In recent years, with the development of modern industry, the transformation and upgrading of manufacturing towards intelligence, automation, and digitalization has become increasingly urgent. Among the many information technologies for realizing “intelligent manufacturing,” RFID industrial identification plays a significant role. It provides support for the underlying data collection of the Industrial Internet of Things (IIoT). RFID boasts advantages such as controllable reading distance, high data security, and rewritability. More importantly, it can fully adapt to harsh industrial environments. Additionally, RFID has extremely strong anti-interference capabilities.

What are some industrial application scenarios for RFID? Let’s take a look.

Automated Guided Vehicle

RFID empowers AGV (Automated Guided Vehicle) logistics vehicles. AGVs, commonly found in logistics scenarios or assembly workshops, are equipped with RFID industrial readers. They can easily track the real-time location and production time of work-in-process vehicles with RFID tags.

AGVs receive task instructions from the host computer via wireless devices, enabling functions such as power management, abnormal alarms, and SLAM laser navigation. The RFID industrial reader transmits the identified RFID electronic tag information to the upper-level system, which confirms the AGV’s location, storage location number, and cargo information, ensuring the accuracy of the work.

PLC and process control

RFID empowers machining. On the one hand, RFID industrial readers can be used to collect data on the number of processing operations of machining tools embedded with RFID tags, allowing for advance prediction of tool lifespan. On the other hand, by pre-setting processing information onto the electronic tags of parts to be processed, when a part is delivered to the processing position, the RFID industrial reader feeds back the processing information to the PLC. Then, the PLC controls and executes the processing task. RFID industrial identification is fast, efficient, and virtually error-free, largely avoiding human error.

Auto Testing

RFID empowers the inspection and testing process. For error prevention of critical workpieces in mixed-flow production, the combination of RFID readers and automatic inspection equipment can automatically determine and verify the correctness of installation. Simultaneously, RFID industrial readers can also perform real-time product location tracking, equipment dwell time, and inspection time statistics. They bind test results, test reports, and products one-to-one. RFID industrial identification seamlessly integrates product information with the MES (Manufacturing Execution System) information system. This significantly improves the informatization level of the production line.
