Paper Abstract

A software platform of the network virtual instrument test laboratory has been developed to realize the network function of the test and signal analysis as well as the share of the hardware based on the data transmission theory and the study of the present technologies of the network virtual instrument. The whole design procedure was also presented in this paper. The main work of the research is as follows. 1. A suitable scheme of the test system with B/S mode and the virtual instrument laboratory with BSDA (Browser/Server/Database/Application) mode was determined. 2. The functions were classified and integrated by adopting the multilayer structure. The application for the virtual instruments running in the client terminal and the network management server managing the multiuser in the test laboratory according to the "Concurrent receival, sequential implementation" strategy in Java as well as the code of the test server application responding the client's requests of test and signal analysis in LabWindows/CVI were developed. As the extending part of network function of the original virtual test and analysis instruments, a software platform of network virtual instrument test laboratory was built as well. 3. The communication of the network data between Java and the LabWindows/CVI was realized. 4. The database was imported to store the data as well as the correlative information acquired by the server and help the network management server to manage the multiuser in the test laboratory. 5. A website embedding Java Applet of virtual instrument laboratory with the on-line help files was designed.
