Design And Implement Of Machine Tests System Based On The Three-dimensional Model

304 Beijing Institute of Metrology of past assessment test operation is concentrated in a specific test center, tests using real equipment, so easily because of misuse equipment damage and because of the limited number of man-made test equipment to extend the test of time, potentially increasing the time , and economic costs.Physical examination for operating a series of problems that exist in the establishment of a computer simulation of the machine test system for examination instead of in-kind operation to address the misuse and damage to equipment problems long examination time, to achieve the best exam results.This paper focuses on measuring equipment, computer simulation of a problem in the design phase is modeled using UML, in the realization stage with Maya, NGrain software such as three-dimensional modeling of the metering equipment, and use Flash technology to show a test centers, using the XML file information storage and, ultimately, Visual Studio 2005 platform, using C # as the programming language used MVC pattern concatenation of all the test centers.The computer examination system include: the theory test system interface program; exam production - maintenance questions, select questions, set up exam; exam choice - generated exam; exam of the show - different manifestations of the test center interface; candidates test Information - conclusions, statistical scores and other functions.System by the end user's acceptance, and put into practical use. To achieve the desired objective, the teachers and candidates alike.Computer examination system itself, there is still a problem, the next time, but also as far as possible the optimization of the computer examination system to make it function better, more friendly interface, a longer life cycle.
