基于HIL的远程控制实验系统设计

Design of Remote Control Laboratory Using Hardware-in-the-loop Simulation

提出了一种基于控制器硬件在环仿真技术的远程控制实验系统解决方案,该方案以机械臂等模拟仿真设备替代真实被控设备,选用Micro850可编程控制器实现对模拟设备的本地控制。远程实验系统采用客户机/服务器模式,支持用户远程下载程序,在线或离线调试,还可以通过Internet进行人机界面操作以辅助实验的开展。实践表明,该系统有利于学生掌握控制器编程与调试等实践技能,降低实验系统造价和维护成本。

A remote control laboratory using hardware-in-the-loop technology was proposed. Instead of the real physical process, physical model of mechanical arm was developed and Micro 850 PLC was used as the local controller. The remote control lab, adopting the client/server structure, can support students to download control program to the remote controller, debug program off-line or on-line, and manipulate the experiments by human machine interface to facilitate the operating of the experiments. Demonstrations have shown that the lab not only helps the students understanding the programming and debugging techniques, but also can reduce the costs in buying and maintaining real devices.
