Abstract: With the rapid development of science and technology marked by digitalization,networking and intelligence,the era of Industry 4.0 has arrived,the basic units of measurement have undergone major changes,and new changes and new trends have occurred in the field of measurement.Under the strong boost of the national macro policy,cloud computing,artificial intelligence,big data analysis and other technologies continue to iterate and mature.As a fertile ground for scientific research innovation and technological progress,digital intelligence empowerment and digital transformation are the key to improve the strategic layout of the laboratory.The digital transformation of the metrology laboratory needs to take the overall consideration of business services and technical research on the basis of multiple dimensions of"human,machine,material,method,environment and measurement"into account,so as to realize the process,dynamic,intelligent and digital management and operation of the laboratory activities.Relying on a favorable policy environment,the metrology laboratory needs to address existing problems and realize digital transformation mainly from the three perspectives of business,technology and value,and take value reconstruction as the main line to realize the mutual influence and iterative upgrade of technology and business.The architecture of metrology digital transformation mainly includes three layers,from top to bottom are application layer,data layer and base layer.The application layer mainly includes the business platform,scientific research platform and management platform,which will develop digital solutions for the overall business process,scientific research project and achievement management,equipment,instruments and personnel scientific management.The data layer mainly includes the data end,data source and data pool,which will analyze and process the data of business services,standards,testing,experiments,scientific research,personnel,etc.,and deeply dig the application value of data.The basic layer mainly includes hardware,software and technology,and uses laboratory instruments and equipment,software system and digital technology to meet the needs of the application layer and data layer,so as to establish a digital metrology laboratory.
