A Study On The Application Of Barcode Technology In Measuring Instrument Calibration

Measurement is a national legal metrological verification institutions, responsible for thenegative public standards of measurement, implementation of compulsory verification andother verification, calibration and inspection tasks, for the government to implement meteringmethod, strengthen the supervision and management measures to provide measurementtechnology guarantee. With the development of information technology, the traditional modeof measurement management have reduced quality, low efficiency, backward mode,responsibility is not clear, verification of information confusion and other issues. Themetrological verification systems are only the traditional verification five elements of man,machine, material," the four elements into account, one of the most important elements of"method" due to its changeability is neglected. The system is in the early stages of design, hetried to find a way to touch the elements into the system, after repeated exploration, theconcept of management system is a sub module of system, the relationship between the fiveelements, with a management system as the link, the five elements of the perfect fusion. Thisconsideration based on the bar code management information system of computer technology,information technology, bar code technology effective combination.The system features using barcode technology itself, the bar code technologyintroduction to metering management information system, improve the speed and quantity ofinformation collection, improve the verification efficiency, enhance the reliability, theverification of validity.This system is mainly composed of a sample chamber sub sub system and managementsystem, laboratory subsystem. The sample chamber subsystem mainly realizes edit and printinstrument information input, bar code printing, equipment orders; laboratory subsystemrealized by edit and print verification, verification of information detection instrument input,certificate; management room subsystem mainly realizes to the statistical analysis of the dataof measurement. Describes the application of barcode technology in metrology managementinformation system and the benefits. This interface uses ASP.NET in the C#language, thedatabase uses SQL server2003. Finally, detailed description of the design andimplementation of login system, a sample chamber subsystem and management subsystem,laboratory room subsystem module.
