The Study Of Web-Based Virtual Laboratory System Of The Measurement And Control Technology Based On LabVIEW

The virtual experimental technology is generated with the development of the computer technology, multimedia and network technology.The first one, this paper introduces the development and status of the technology of the virtual instruments and the virtual experiment.The second one, this paper constructs an virtual experiment of the measurement and control technology through two clues. One is the Knowledge Learning order which makes up an expansible virtual platform of a software and basic hardware of the personal computer, and the another is designed by the all-around experiment, which is based by the laboratory existing hardware conditions. This article focuses on the network platform for virtual experiment involved in the construction of some important technology ,such as Data Acquisition,signal analysis and processing,Response Analysis System,Report Generation,Remote panel and DataSocket. This article focuses on the vibration mode of experimental platform as a typical example of the comprehensive test. The platform includes the main components and design ideas, the various functional modules of the design and implementation, and so on. Meanwhile, the vibration mode of experimental platform do a series of examples and analysis of their results for the students in the experimental application.Finally, this paper studies dynamic servers Home development tools and ADO.NET data storage technology based on the ASP.NET. This paper combined with LabVIEW in network technology, to achieve a virtual network of the building site.This paper proposed the construction of the basic ideas and feasibility study. For the latter, because of the limitation of the hardware experimental platform, this paper focuses on the achieve method of long-distance virtual experiment, and focused on how to achieve long-range data acquisition by LabVIEW.This experimental system, constructed for mechanical electronics and information related disciplines, rational used the existing laboratory resources, construction of the experimental platform adopt principles of open and expand, for the purposes of student's instruction, fully mobilize the enthusiasm of the students to learn and subjective initiative, has strong practical value.
