System and method for embedding machine-readable calibration and measurement capability data into dcc

A system for embedding machine-readable calibration and measurement capability data into a DCC, comprising a WEB service subsystem, an acquisition subsystem, a message queue subsystem, and a storage subsystem, wherein the WEB service subsystem is connected to the acquisition subsystem through the message queue subsystem, and the storage subsystem is connected to both the WEB service subsystem and the acquisition subsystem;

• the WEB service subsystem is configured to online view and manage calibration and measurement capability data, a digital calibration certificate, and trusted timestamp data;
• the acquisition subsystem is configured to acquire data from a Bureau International des Poids et Mesures website, regularly acquire calibration and measurement capability data based on acquisition configuration, generate a digital calibration certificate based on an acquisition result, and affix a trusted timestamp;
• the acquisition subsystem comprises an acquisition service module, a DCC generation service module, and a trusted timestamp affixing service module;
• wherein the acquisition service module is connected to a Key Comparison Database website via the Internet, and is configured to provide a capability of acquiring data from the KCDB website of the Bureau International des Poids et Mesures;
• the DCC generation service module is configured to generate a digital calibration certificate, parse calibration and measurement capability data, and analyze a unique identifier of the data, which serves as a unique traceability identifier to the KCDB;
• and is also configured to analyze calibration fields to which the data belongs, comprising physics, ionizing radiation, and biology and chemistry, and generate a corresponding digital calibration certificate based on built-in digital calibration certificate templates for the calibration field types;
• the trusted timestamp affixing service module is configured to provide and affix a trusted timestamp and generate a trusted timestamp credential by calling a trusted timestamp interface based on contents of the digital calibration certificate;
• the message queue subsystem is configured to perform asynchronous communication between the WEB service subsystem and the acquisition subsystem;
• and
• the storage subsystem is configured to store information and data processed by the WEB service subsystem and the acquisition subsystem.
