摘要/Abstract

摘要： 针对PLC调试传统培训方式不能多方位展现被控对象运行状态的问题,以典型的控制对象燃气锅炉为例,基于虚拟现实技术开发了一个PLC虚拟仿真培训系统。系统由上位机和下位机组成,通过RS232数据总线连接。上位机采用3ds Max对设备装置进行建模、渲染,在Unity3D中构建完整地虚拟场景。下位机以PLC为控制核心设计控制板,利用通信接口模块实现PLC与虚拟场景之间的数据传输,完成对虚拟锅炉的控制。经测试系统可正常运行,学员能够安全高效地编程并进行调试,了解和生产现场相似的工艺流程,提高培训效率,缩短培训周期,减少培训成本,具有较高的经济性和安全性。

Abstract: In view of the problem that traditional training methods for PLC debugging can not show the running states of controlled objects in full angles, a PLC virtual simulation training platform is designed based on virtual reality technology. The system is composed of upper computer and lower computer connected by RS232 bus. The upper computer uses 3ds Max to model and render facilities, and uses Unity3D to construct the complete virtual scene. The lower computer designs PLC control board to control the virtual gas-fired boiler, which transmits data between PLC and virtual scene through the communication module. The test result indicates that the system operates successfully. The learners can write and debug programs safely and efficiently. What's more, they can directly feel the processes similar to production sites, which improves training efficiency, shortens training cycle and reduces the cost of same degree training.
