Design And Implementation Of The Comprehensive Business System Of The Service Of Legal Metrological Verification

The design and development of the Service of Legal Metrological Verification comprehensive business system is to ensure the development of every business of legal metrological verification service, comply with each assessing requirements of JJF1069 Rules the Examination of the Service of Legal Metrological Verification published by General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, effectively improve metrological verification service working efficiency and lower mistake rate, and ensure to supply fair, accurate, reliable metrological verification and verification results with law force.It is noted that, through the whole project design cycle including system requirement analyses and system modeling, the Unified Modeling Language or UML is used as standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems;. NET is used as a programming and development platform; MVC design pattern is used.This paper analyzes the systems development background, and briefly describes the major work done; It gives the detailed requirement analyses and system architecture; It detailedly describes the realization of core functional modules, database design and database access.In this paper, the following key issues are solved:First, JJF1069 Rules for the Examination of the Service of Legal Metrological Verification must be strictly carried out in accordance with the requirements of standardized for Verification / calibration / test business developed in The Service of Legal Metrological Verification. In the existing institution, artificial or single computer management mode is unable to handle the business aspects of the deployment and use of resources to provide effective control mechanisms; it is unable to accord with JJF1069 requirements. In this paper, we analyzed the full process of verifying, calibrating and inspecting with Unified Modeling Language (UML), and built its function structure, generalized the procedure of verifying, calibrating and inspecting for an accredited calibration organization.Second, the system uses MVC design pattern and ASP. NET achieve system design to ensure that the system can be a good maintenance and expansibility.The success of system development shall make verification service satisfy examination criterion, at the same time effectively improve the service inner management level and working efficiency, reduce mistake rate, realize resource share between and inner the services and ensure metrological verification service to supply fair, scientific, accurate, high-efficient metrological verification, calibration and inspection service to the society.
