Research And Development Of Virtual Laboratory System Based On C/S

The virtual reality technology takes the computer technology as a core. It is based on the immersive interactive environment of the calculable information. It synthesizes audition, vision and sense of touch as a whole. It imitates the real reappearance technology of the three-dimensional space. It is applied in many fields of the modern technology. And its most important goal is the real experience and convenient and natural man-computer interaction. It creates one harmonic man-computer environment which resembles the objective environment but surmount the objective space and time, and can immerse and control itself. It is also called the operable space made up of the multi-dimensional information. The virtual reality technology unifies contents of many disciplines, and covers many key technologies including dynamic environment modeling technology, real-time three-dimensional graph production technology, solid display and sensor technology, system integration technology and so on.The virtual laboratory system is one of the important applications of the virtual reality technology. Scientific experiments and study by virtual laboratory system can bring historical revolution of the traditional teaching instruments. The omnidirectional, multi-level, multi-model practical teaching environment by virtual laboratory system can entirely improve students' practical operationalskills and technological practical skills.The virtual laboratory system of composition theory uses complete virtual laboratory model and takes COP2000 experimental instruments as the simulation. The system interface is realized by photos. Its partition and disposal use image processing software of ACDSee, to work achieved in the computer laboratory at the high simulation results. And the system makes use of the enclosed nature, continuity and portability of JAVA to carry on the simulation of experimental instruments and contents. At the same time, by utilizing SOCKET mechanism of JAVA language and taking TCP/UDP protocol, the system realizes the functions of inspecting from server machine to client machine and the communication from point to point or multicast between server and client. This system can be connected with SQL SERVER 2000 to complete the real-time transmission and management of data in network.This paper holds a thorough discussion on virtual reality technology. It demonstrates the general design idea and design method of the system particularly, summarizes the advantage and disadvantage of the system, and puts forward the perfect suggestion.
