The digital transformation of metrology is one of the most active activities in the field of metrology at present, where the digital calibration certificate (DCC) being developed is the topic receiving the most concern in the current digital transformation. In practical industrial applications, the issue of storage carrier for the DCC plays a crucial role in its promotion and implementation. To address this issue, a DCC meta-model called DCC-Lite schema has been designed along with a corresponding processing method. This solution involves compressing and segmenting the DCC to make it suitable for storage using RFID tags. These RFID tags are affixed to the instruments and accompany them throughout their usage. Additionally, the DCC-RFID processing system has been developed to validate the effectiveness of the DCC meta-model and its corresponding processing method within a wireless temperature acquisition system. Experimental results demonstrate that the system successfully reads and writes the DCC stored within the RFID tag group. Furthermore, it enables automated parsing of the DCC calibration data by the machine and real-time compensation of measurement data to reduce measurement errors.
计量学的数字化转型是当前计量领域最活跃的活动之一，其中正在开发的数字校准证书（DCC）是当前数字化转型中最受关注的主题。在实际工业应用中，DCC的存储载体问题对其推广和实施起着至关重要的作用。为了解决这个问题，设计了一种名为DCC-Lite模式的DCC元模型以及相应的处理方法。该解决方案包括对DCC进行压缩和分段，使其适合使用RFID标签进行存储。这些RFID标签贴在仪器上，并在仪器的整个使用过程中伴随。此外，还开发了DCC-RFID处理系统，以验证DCC元模型及其相应处理方法在无线温度采集系统中的有效性。实验结果表明，该系统成功地读取和写入了存储在RFID标签组中的DCC。此外，它还能使机器自动解析DCC校准数据，并对测量数据进行实时补偿，以减少测量误差。
