Research On The Local Network Laboratory Based On Virtual Instrument

With the development of science and technology, colleges and universities are faced with the problem of constant changes in personnel training mode. Training high-quality personnel is the goal of all colleges and universities. For a university of science and technology, the laboratory teaching is the key to the training of student, so each university is increasing the input in the laboratory building. Laboratory is a place at where students study and teaches engaged in scientific research. Laboratory equipment is usually used as a measure of Higher Education, and it also a important quality to evaluate the scientific research level of the university. In the teaching of the university, the knowledge and the practice are closely related especially in some subject with strong practice. Experimental is crucial to train students ability in practical operation and solving practical problems. The practical ability of the students main obtained through the experiment.Construction of the first papers on the relevant technical and network monitoring laboratory with a brief presentation, analysis, The choice of the United States NI LabVIEW platform topic Laboratory Virtual Instrument Engineering Network Virtual Instrument Experimental platform for the development of network and virtual instrument technology to start detailed briefing on the establishment of virtual local area network and associated laboratory techniques, the characteristics of this technology. Construction of a virtual experiment on how effective teaching system, the concrete programs and measures. Meanwhile examples demonstrate the features and advantages of a virtual network. Virtual students can feel that they are in the experimental process, as working hand-in-hand for the same kind of teaching scene, Experimental equipment from numerous management problems, so that a teacher can face many students experimental guidance Simultaneously, the scene while students can experiment design and verification, so that students quickly understand when teachers on the court, make teaching more efficient.Based on the construction of LAN Virtual Laboratory, the paper have studied the following works: The domestic and aboard situation of virtual laboratory was reviewed and the background and significance of the network of laboratories was introduced in the first part; the virtual instrument technology and the LabVIEW software was induced and their characteristics and advantages using them to program is given in the second part; the concept of network-based virtual experiments, architecture and network communications were made in the third part; A platform to build a network laboratory structure specifically the client and server technology were given in the fourth part gives; A few examples of the electronic virtual experiment was designed in the development of laboratory network. At the end, it points the booming prospects for of LAN and a representative experimental method in the experiment teaching.
