Design and Implementation of Digital Calibration Certificate for RFID Tag Storage

Area of Science:

• Metrology
• Digital Transformation
• Measurement Science

Background:

• Digital transformation is revolutionizing metrology, with digital calibration certificates (DCC) as a key focus.
• Efficient storage solutions are critical for the widespread adoption of DCC in industrial settings.

Purpose of the Study:

• To develop a novel meta-model and processing method for storing DCC on practical storage carriers.
• To validate the effectiveness of the proposed DCC storage solution in a real-world application.

Main Methods:

• Designed the DCC-Lite schema, a meta-model for DCC.
• Developed a method to compress and segment DCC for storage on RFID tags.
• Implemented a DCC-RFID processing system and tested it with a wireless temperature acquisition system.

Main Results:

• Successfully demonstrated the read/write capability of DCC stored on RFID tags.
• Validated the automated parsing of DCC calibration data by machines.
• Showcased real-time compensation of measurement data to minimize errors.

Conclusions:

• The DCC-Lite schema and RFID-based storage method are effective for digital calibration certificates.
• The developed system enhances metrology efficiency through automated data processing and error reduction.
