The Design And Accomplishment Of Remote Virtual Labs In LabView's Vacational Schools

Laboratory teaching is an important link in teaching,but the Experiment teaching is a very important part of daily teaching in science and engineering vocational schools.With the rapid development of computer and network,a new teaching model---remote network teaching come into being.The combination of remote network teaching and experimental teaching will build a remote virtual experiment platform,which can effectively solve the problem that traditional laboratory was effected by equipment,space,cost and other factors.Firstly,according to the technical points of the virtual instrument experiment platform and the actual situation of the electrical major in vocational schools,this paper identified the proper hardware equipment and experimental plan.Secondly,the B/S networking model which is suitable for the platform and users is determined by analysis and compare the network model.Thirdly,eight experimental design of electrical major in vocational schools was finished by taking advantage of Lab and VIEW software.The eight experiments are measurement of volt-ampere characteristics of diodes,JK Trigger Virtual Experiment,Shift register virtual experiment,Counter virtual experiment,First-order low-pass circuit frequency response virtual experiment,Experimental Study on Frequency Characteristics of RLC Series Circuit,Three-factor method for solving first-order dynamic circuit experiment,Zero-Input Response Experiment of Second-order Circuit.And then,with Dreamweaver to design the content of virtual platform,and with remote panel to combine web –making technology and VI panel-connecting technology,the virtual remote experiment was achieved;and the site was built by IIS sever setting web site.Finally,the operability of this platform was verified by remote user landing.
