Minnan University Of Science And Technology The Design And Realization Of Virtual Experiment System For Electrical And Electronic

The design goal of virtual experiment system for electrical and electronic virtuallaboratory is the final realization of the virtual lab, including computer hardware,software and various kinds of sensors, the user can interact with the physicalexperimental equipment in this virtual environment, reach a kind of be personally on thescene feeling. Because of the rapid development of the network technology of remotecontrol, so that the design of the virtual laboratory is a possible. It will make thetraditional hardware laboratory is faced with reform, will break the traditional mode ofhardware experiment teaching.The main work of this thesis is to solve the bottleneck of Minnan science andtechnology development and construction of electrical and electronic laboratory school,proposes a virtual experiment system of client, and related to the function of the systemand the task of analysis, carry out the following work: system interface design, databasedesign, electrical drawing sub components toolbox to design, experiment circuitschematic design of automatic generation and network table file analysis, circuitdiagram and the optimization and adjustment of the design. In-depth research from threeaspects: first, establish electronic components database and solve the database relationbetween the call, in this part the data table structure for various types of electroniccomponents, instruments, research and design, and established the data and thecorresponding relation between the tables. Secondly, the automatic generation andoptimization process of the electric principle diagram as the core part of this paper,conversion in this chapter mainly discusses the method by means of mathematicalmodeling to achieve the physical circuit to the electric principle diagram theory, andcalculate the mathematical matrix function to realize the conversion value. Finally, tosolve the problem of data exchange between the client and the server, the overallfunction of system are given. The test scheme and operation.Any test circuit are interconnected by the relationship between the limitedelectronic components, instruments and their, the article analyzes the characteristic ofelectronic components, instrument limited, study their connection between experimentalenvironment, through the mathematical modeling method to solve the mappingrelationship between experimental circuit and instrument with electrical principle diagram, and has been verified in the system test, the operation effect of the systemreaches the design goal. Design of virtual experiment system for electrical andelectronic students to change the teaching mode of hardware experimental laboratory toa device, the realization of the use of new technology of network virtual realityexperimental process, explore the development requirements of the virtual lab of hisown.
