UHF Flexible Anti-metal RFID Tags in Smart Manufacturing

Against the backdrop of the accelerated integration of intelligent manufacturing and Industry 4.0, enterprises are increasingly demanding real-time, accurate and visual production management. Ultra-high frequency (UHF) RFID has become an important technical support for smart factories and lean production with its advantages of contactless identification, batch reading and long-distance communication.

UHF flexible anti-metal RFID tags are widely used in metal environments such as production line monitoring, asset management and logistics tracking due to their good resistance to metal interference and environmental adaptability.

1. System architecture overview: three-layer closed-loop management system

The system consists of data acquisition layer, data communication layer and management execution layer, forming a complete digital process from on-site perception to decision optimization.

1. Data acquisition layer

It consists of UHF flexible anti-metal RFID tags and read-write devices. It is recommended to use flexible anti-metal tags such as TAG-R531/R583, which are attached to the surface of metal work pieces, molds, etc. Through the combination of Chainway C72 handheld terminal and fixed reader, multi-point coverage and mobile inspection are achieved, and the on-site information is visualized with MES terminal and electronic billboard to improve response efficiency.

2. Data communication layer

Relying on communication facilities such as industrial Ethernet, wireless AP or 5G, the tag data is uploaded to the middleware, connected to the ERP/MES/WMS system, and efficient data synchronization is ensured.

3. Management execution layer

Responsible for data processing and analysis, monitoring production progress, equipment utilization and material flow, supporting abnormal warning and scheduling optimization, providing complete data traceability, and meeting quality management needs.

2. Core performance of UHF flexible anti-metal Rfid Tag

Working frequency band: 902~928MHz, in line with EPC Gen2 standard

Reading distance: TAG-R531>8 meters, TAG-R583>7 meters, outdoor reading can reach more than 10 meters with high-performance handheld devices

Environmental adaptability: PET flexible packaging, support bending and attachment, working temperature -20℃~70℃, humidity resistance <95% RH

Data storage: Impinj Monza R6-A chip, 96bit EPC, 64bit user area, 100,000 erase and write life

Widely used: asset management, warehousing and logistics, production process tracking, quality traceability, etc.

3. Typical application cases

Metal processing workshop: replace easy-to-wear barcodes, realize automatic identification of metal workpieces, and improve circulation efficiency

Equipment maintenance management: label-assisted inspection, record equipment status and maintenance, support predictive maintenance

Supply Chain Management: Automatic identification and verification of key nodes to improve logistics efficiency and avoid missed shipments

4. Data writing specifications and security recommendations

The written content is controlled within 64 bytes, including model, batch, serial number, etc.

The chip's built-in security protocol or external encryption can be enabled to protect sensitive information

After writing, it must be read back for verification to ensure data integrity

Set access passwords to restrict unauthorized operations

It is recommended to combine QR codes and other identifications to achieve double verification
