The Research And Implementation Of Extensible Remote Virtual Hardware Experiment Platform Software System

In recent years,with the rapid development of network information technology,the traditional digital circuit experiment is also experiencing the information of the change,a variety of forms of remote experiments,virtual simulation experiments have been adopted at home and abroad colleges and universities.At the same time,China also proposed to build a national virtual simulation experimental teaching center and called the promotion of Chinese university MOOC platform,therefore,the traditional digital circuit class experimental way to change is an important part of the future teaching digitalization.Currently,around the remote virtual simulation experiment,there are usually two ways:First,the establishment of local software simulation;the second is through the camera or network to conduct remote experiments indirectly.These two practices have some drawbacks,the former can not give users the real experience of the experiment,while the latter will lead to experimental equipment complex structure,high cost.Therefore,this thesis presets a method of scalable remote virtual experiment based on real hardware platform and virtual simulation of the upper layer.First of all,this thesis analyzes the overall requirements and scalable virtual features of the system,and proposes a remote hardware experiment platform scheme combining hardware support and software simulation.On this basis,the overall architecture of remote virtual hardware experiment platform software system is designed.Secondly,this thesis studies the scalability of the system module under the open architecture,desigpns the "global architecture programming model" suitable for the system,that is,the top layer component definition,the middle layer plug-in implementation,and the underlying XML can be configured.This thesis also designs the communication mechanism and the message data format protocol which are suitable for the system,and realizes the scalability of the system function and the simulation hardware board.Thirdly,this thesis uses the concept of hardware emulation layer to complete the geometric object transformation and two-dimensional planar simulation of three-dimensional space research,on the basis of the four-tuple data model to complete the three-axis accelerometer movement model modeling study,and implemented the model through OpenGL.Finally,the system completes the realization of the entire remote virtual hardware experiment platform software system,and the relevant sub-functional part of the test,the test results are good,verify the correctness of the design of the system.
