Abstract

The invention discloses a machine readable calibration measurement capability data embedding DCC system and method, and belongs to the field of metering and calibration measurement, the system comprises a WEB service subsystem, a collection subsystem, a message queue subsystem and a storage subsystem, the WEB service subsystem is connected with the collection subsystem through the message queue subsystem, and the collection subsystem is connected with the storage subsystem through the message queue subsystem. The storage subsystem is respectively connected with the WEB service subsystem and the acquisition subsystem; according to the system, calibration measurement capability data are collected from a BIPM website at regular time and embedded into a related digital calibration certificate, and meanwhile, a credible timestamp is generated for the digital calibration certificate. The calibration measurement capability data in the KCDB is regularly acquired and dynamically updated through API calling, a traditional manual query mode is replaced, manual intervention is remarkably reduced, the accuracy, effectiveness and authority of data use are improved, the user experience is greatly improved, and the problem that the actual user experience is seriously affected in the prior art is solved.
