PLC虚拟仿真实训教学平台建设探索

摘要

基于VRML开发了PLC虚拟仿真实训平台。该平台采用B／S架构，客户端使用ActiveX完成3D虚拟现实场景的渲染，核心功能模块包括与仿真软件交互模块、原理图计算模块和原理动画模块，可供学生进行理论学习、原理图绘制及实物接线、程序编制、完成并提交实训报告。学生可不受时间和空间的限制地完成虚拟互动实训，完成PLC软硬件协同设计，实现完整的系统搭建以及逼真场景的仿真调试。%Based on VRML , the virtual simulation platform with B/S architecture can achieve the virtual interactive training ,which enables students to access the platform through connected PC without the limitation of time and space . After completing co‐design of the hardware and software , the integrity system construction ,and realistic scene simulation and debugging can be conducted on the platform .
