The LabVIEW Long Distance Experiment Management System Based On Web

Long distance experiment is the combination of computer technology, networktechnology and laboratory management. It solves the inadequate resources in thetraditional experimental mode. Students, teachers can whenever and wherever possibleuse of laboratory resources,and can be convenient for online data exchange, informationinteraction, results and statistics.it breaks the traditional laboratory in spatial andtemporal constraint. In the case of computer and virtual instrument technology, Longdistance experiment management system can be used as the main tool of Long distanceexperiment teaching. Virtual instrument, universal and intelligent network is being toactved.This article take LabVIEW as the technical means,and emphatically introducesthe use of virtual instrument technology in the laboratory management and experimentteaching. During developing the system and according to the actual situation of LeshanNormal University,the author had a enough investigation about the system requirements,got real requirements by discussing with lab assistant、teachers students in detail, anddesigned related long distance experiment modules. After testing, the system can meetthe requirements in the two aspects of daily management of the actual experiment andexperiment teaching.It can adapt the special requirements and needs that was putforword by the users, and has strong expansion ability and applicability. In actualapplication, we can do some modify and add function work to the long distanceexperiment according to the teaching requirements. Also it has reserved interface toexchange data with other related system. At the same time we also can expand thesystem function according to the requirements of lab assistant.1.This paper introduced the research background and the concept of the virtualinstrument laboratory and long distance experiment management system. At present,many universities have a large number of research results that had beening put into theexperiment, and have a good effect.2.This paper gave A detailed study of some related technology to completingLong distance experiment system, including Long distance virtual instrumentsystem,the connecting of LabVIEW and SQL database and the construction of remote network system.3. This paper studied and designed daily experimental management system basedon JSP,and had a detailed description of the online laboratory equipment management,the user login module, the function of experiment booking,the resource query ofexperiment teaching, the database design.4.This paper studied and designed LabVIEW-based remote virtual experimentmodule: Modulation and demodulation experiment based on LabVIEW,2ASKexperiment based on LabVIEW, the phase locked loop in high frequency circuitexperiment based on LabVIEW, simple pendulum experiment based on LabVIEWand Single chip microcomputer.
