Application Research Based On Technology Of Computer's Simulation In Vitual Designing Of The Laser-printer's Module

The Visual Simulation System is composed of hardware,network,simulation software. The Visual Simulation System uses C++ language,VRML language and Matlab program language. Its running also depends on Matlab,Visual C++,VRML plug-in and Internet Explorer, so how to collaborate all software is a very important problem.This paper analyzes the structure of the hardware and software in the Visual Simulation System. Multiple softwares work together to develop an actual system. This paper's work focus on the below 4 items, (1) The 3-D model of laser print-machine and other working scene are made by Pro/E software tool. (2) The simulink toolbox of Matlab has a quick and visual modeling abilities. Using this toolbox to build System Simulation model which provides running parameters to the Visual Simulation System. And in simulink toolbox's graphic System Simulation Model is easy to adjust the parameters of the model; and it also is easy to add other model; (3) by using Visual C++ programming tool, designing the User Interface Program on which 3-D scene is showed. Users can manipulate the running scene by the control of User Interface; (4) Let the User Interface Program call the Simulation Model by the Engine functions of Matlab; and by using C/C++ language writes S function program of Matlab, running parameters can send from System Simulation Model to the User Interface Program via S function block.The completed Visual Simulation System can simulate the running of the laser print-machine. Viewer can observe the running of the print-paper from different viewpoints, and control the velocity and direction of the print-paper, the running parameters such as velocity are displayed. The software in this paper is developed,debugged,run on Window XP platform.
