The Remote Virtual Platform And The Research Of LabVIEW Experiments

In order to enhance information technology service capabilities for the economic development of Shanxi Province, and to promote efficient allocation and comprehensive integration of social scientific and technological resources,to enhance scientific and technological innovation for achieve the closely connection requirements of economic social development and science technology. In this paper, sharing platform for large-scale instruments in Shanxi Province early projects on the basis of initial results continue to deepen, improve and expand the preliminary work, deeply reserach the virtual form of large-scale instruments and build large-scale scientific instruments virtual experiment base, build remote virtually laboratory and realize remote experiments on LabVIEW. This paper mainly studies the following questions:Firstly, we will read a large number of domestic and foreign literatures, deeply study and research the remote virtual laboratory which has been established, deeply introduce the concept and characteristics of the virtual laboratory, and derive the remote virtual laboratory to solve major problems based on the existing conditions.Secondly, based on the J2EE frame, we will set up an experimental platform named "Computer and Software department virtual laboratory, Taiyuan University of Technology School". Allows the user to remotely log on to our platform, and access our servers to carry out related experiments.Thirdly, we will design the remote expetiment platform of LabVIEW and use the software to complete some experiments which have been published on the Web server, allowing users to remotely access these experiments, reaching the purpose of the remote share. Such as: voltage signal acquisition and filtering, the virtual oscilloscope for data analysis, remote use of LabVIEW provides functions for solving nonlinear equations, the use of LabVIEW compare specific signal windowed spectrum to non-windowed spectrum, the use of LabVIEW for specific signal analysis and computing, etc.In the experiment of remote use of virtual oscilloscope for data analysis, on the client, users only need to save measured data that will be automatically saved to the database, the virtual oscilloscope on the will access the database and the data will display in the form of the waveform. On the server side, managers publish the experiments in the Web page, enabling users anywhere and anytime remote access, and download experimental data.
