Remote Testing System Based On Virtual Instrument

With the development and combine of technology of computer, network and electron, the technology of virtual instrument and network testing building on Internet are be further developed, which make it easy to set up complicated, remote and wide area the network testing system. The system provide convenience to realize resources share and finish together testing, especially in the place which is dangerous and unable to get in, such as nuclear explosion, the bottom of the sea, the mountain area of high and cold, the internal part of channel and so on. So it is necessary to design the remote virtual testing system.Remote testing system based on virtual instrument is a network testing system in Internet, which is based on the technology of virtual instrument, Web publish and computer network. In order to design and realize the remote virtual testing system, this dissertation includes the following work:First, the dissertation analyze the model of network testing system network test system, and bring forward to design the remote virtual testing system with the C/S and B/S hybrid model, and analyze and study the technology of virtual instrument, remote data acquire and remote data transmission.Then, according to system requirements, design the overall program of remote virtual testing system based on the LabVIEW software platform, and through designing on-site testing server unit, server monitoring unit and remote users testing unit to complete the detailed design of the system. At the same time, design and realize the virtual instrument system, which test the temperature and noise based on Computer chassis.Finally, through actual test, realize the remote testing temperature and noise around computer chassis, the system achieved the expected goals.Remote testing system based on virtual instrument uses the technology of computer network, virtual instrument and features of LabVIEW language, realize the network, remote, automated of testing system. Remote virtual test system reduces costs and improves the efficiency of the test system. Remote virtual test system will be wide applied in the field and range of automatic control, monitoring and control, teaching and research.
