Description

Technical Field

[0001] The present invention belongs to the field of metrology and calibration measurement, and in particular relates to a DCC system and method for embedding machine-readable calibration measurement capability data. Background Art

[0002] Calibration measurement capability (CMC) is an important part of the international metrology system. The accuracy, completeness and authority of its data are of great significance to cross-border trade, scientific research and industrial development. At present, the International Bureau of Weights and Measures (BIPM) publishes globally recognized CMC data through the Key Comparison Database (KCDB), which contains information on the services provided by participating institutions through internationally recognized CMCs, as well as core and supplementary comparison information to support these CMCs. All data listed in the KCDB have been reviewed and approved in the CIPM Mutual Recognition Agreement (MRA), so it is also called the CIPM MRA database. Among them, CIPMMRA is a framework for national metrology institutes to demonstrate the international equivalence of their measurement standards and the mutual recognition of the calibration and measurement certificates they issue.

[0003] KCDB's CMC data has been digitally provided by participating institutions since October 29, 2019, with access and control over the content. In 2021, BIPM provided an application programming interface (API) for searching CMCs in KCDB. The API can be accessed through the KCDB page on the BIPM website, and an official manual (API KCDB Guide) is provided to explain how it should be used to software developers. Its purpose is to promote machine readability of data in the BIPM database and to establish a machine-readable format for its reference publications, which enable direct communication between machines. The data provided by API KCDB are responses to search queries on CMC.

[0004] Calibration agencies currently haven't widely adopted the KCDB's machine-readable CMC data, especially those capable of issuing digital calibration certificates (DCCs). They haven't yet effectively integrated API KCDB CMC data with their DCC systems, or found a method for embedding machine-readable CMC data into machine-readable DCCs. This requires users to perform complex format conversion and data integration, severely limiting the widespread adoption of DCCs in metrology. Summary of the Invention

[0005] In response to the above-mentioned deficiencies in the prior art, the present invention provides a machine-readable calibration measurement capability data embedded in a DCC system and method, which solves the problem that the prior art requires users to perform complex format conversion and data docking work, which seriously affects the actual user experience.

[0006] To achieve the above-mentioned object, the present invention adopts the following technical solution: a machine-readable calibration measurement capability data embedded in a DCC system, 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 via the message queue subsystem, and the storage subsystem is connected to the web service subsystem and the acquisition subsystem respectively;

[0007] The WEB service subsystem is used to view and manage calibration measurement capability data, digital calibration certificates, and trusted timestamp data online.

[0008] The acquisition subsystem is used to collect data from the BIPM website. It is also used to obtain calibration measurement capability data at regular intervals based on the acquisition configuration, and to generate a digital calibration certificate based on the acquisition results, with a trusted timestamp.

[0009] The message queue subsystem is used for asynchronous communication between the WEB service subsystem and the acquisition subsystem;

[0010] The storage subsystem is used to store information and data processed by the WEB service subsystem and the acquisition subsystem.

[0011] Furthermore: the WEB service subsystem includes a WEB API service module, a user management module and a business data management module;

[0012] The WEB API service module is deployed in the local area network (LAN), which is connected to the PC and is used to provide WEB page services to users and provide reverse proxy services for the user management module and business data management module.

[0014] The business data management module is used to provide management services for business data, including querying and deleting calibration measurement capability data, querying and deleting digital calibration certificate data, and querying trusted timestamp credentials.

[0015] The beneficial effects of the above further solution are: the collection service module does not collect data that has been collected, so as to reduce the collection volume; the collection service module adopts a triple-try mechanism to ensure the efficiency of data collection.

[0016] Furthermore: the acquisition subsystem includes an acquisition service module, a DCC generation service module and a trusted timestamp endorsement service module;

[0017] Among them, the collection service module is connected to the KCDB website through the Internet and is used to provide the ability to collect data from the KCDB website of the International Bureau of Weights and Measures;

[0018] The DCC generation service module is used to generate digital calibration certificates, analyze calibration measurement capability data, and analyze the data's unique identifier, which serves as a unique identifier for traceability to the KCDB. It also analyzes the calibration domain to which the data belongs, including physics, ionizing radiation, and biology and chemistry, and generates the corresponding digital calibration certificate based on the built-in digital calibration certificate template for the calibration domain type.

[0019] The trusted timestamp service module is used to provide a trusted timestamp and generate a trusted timestamp credential by calling the trusted timestamp interface based on the content of the digital calibration certificate.

[0020] Furthermore: the message queue subsystem is provided with a message queue, which adopts an inter-process message queue service, including a data collection request queue, a collection result return queue and a data collection log queue;

[0021] Among them, the data collection request queue is used to transmit the collection start message from the business data management module to the collection service module;

[0022] The collection result return queue is used to transfer the collection result information from the collection service module to the business data management module;

[0023] The data collection log queue is used to transfer log messages from the collection service module to the business data management module.

[0024] Furthermore: the storage subsystem is provided with a database;

[0025] Among them, the database uses a relational database to store information and data in the processing process, including user information table, authority information table, calibration measurement capability data table, digital calibration certificate data table, trusted timestamp credential data table, and collection log information table.

[0026] A method for embedding machine-readable calibration measurement capability data into a DCC system is provided, and is applied to embedding machine-readable calibration measurement capability data into a DCC system. The method comprises the following steps:

[0027] S1. Based on the release time of the collected data, collect the calibration measurement capability data after the latest release time;

[0029] S3. Sign a trusted timestamp based on the generated data calibration certificate content to generate a trusted timestamp credential;

[0030] S4. Save the calibration measurement capability data, digital calibration certificate and trusted time stamp credentials.

[0031] Furthermore: in said S1, the method for collecting calibration measurement capability data is specifically:

[0035] Further: S3 specifically includes:

[0036] The SHA256 value of the content is calculated based on the generated data calibration certificate content as the fingerprint information of the data. By calling the trusted timestamp interface, the returned trusted timestamp credentials are received. The trusted timestamp interface is provided by an authorized trusted timestamp signing agency.

[0037] Furthermore: in said S4, the calibration measurement capability data is saved in the original data table, the digital calibration certificate is saved in the DCC data table, and the trusted timestamp credential is saved in the trusted timestamp credential table.
