Research And Design On Virtual Training Room Of Premises Distributed Systemin Secondary Vocational College

With increasing emphasis on vocational education in China, more and more students can receive education in secondary vocational colleges and higher vocational colleges. With the expansion of the number of students, the problem that the condition for students’practical ability training can not meet the demand shows. The inadequate condition for students’practical ability training mainly includes the following aspects: insufficient facilities, restricted teaching time and teaching space, dangers of practical ability training, teaching contents mismatching with operation in reality. At the same time, the development of computer Networks, multi-media, virtual reality technique and graphic technology provides technology support to the construction of virtual experiment system.This paper does intensive study based on the characteristics and fundamental principles of courses with premises distributed system in secondary vocational colleges, putting forward the concept of premises distributed system in secondary vocational colleges, and doing research and designing on premises distributed system. This paper firstly introduces the state of development of virtual reality and virtual experiment in home and abroad. Then it elaborates the whole process that how virtual experiment system turns into reality. This paper emphasizes on research on ways of building virtual device model and virtual experiment scene of virtual experiment system,-and research on the exploitation of virtual experiment system which not only provides experimenters plentiful, verisimilar, normative component and equipment, but also sets up operation platform for convenient operation.The judgement mechanism is added into the operational controlling of virtual experiment platform. When the operator is doing operation, the mechanism will judge his operation if it is in accordance with the standard and the real project requirement and put forward errors. After the experiment, the mechanism will generate experiment report.At last, this paper makes summary on research work on the application of virtual training in premises distributed system in secondary vocational college and further proposes the research direction.
