摘要
为解决机械设备在研发设计完成时,必须借助实物PLC对设备的性能进行虚拟仿真验证,并且不能对PLC程序的合理性进行检验等问题,提出了虚拟联动仿真的概念。采用构建虚拟设备与虚拟PLC运行环境的方法,利用高级语言实时传递和处理虚拟PLC与虚拟设备之间的信号,并将运行情况和故障等信息在虚拟场景中表现出来,最终实现了不依赖实物PLC对机械设备的性能进行虚拟仿真验证,同时可以检验PLC程序的合理性,拓展了虚拟仿真的新思路。以喷印机运动控制仿真为例,论述了虚拟联动仿真技术的必要性与可行性。
The concept of virtual linkage simulation was put forward to solve the problems of using physical PLC for virtual simulation of equipments and inability to inspect rationality of PLC program in the completion of research and design. Virtual devices and virtual PLC runtime environment was constructed using high-level language real-time transmission and signal processing between virtual PLC and virtual devices. The operation and fault information in the virtual scene was manifested. Ultimately, virtual simulation on mechanical equipments not depending physical PLC was realized. The virtual linkage simulation can also test the rationality of PLC program, which expands the new ideas of vir- tual simulation. The necessity and feasibility of virtual linkage simulation technology was discussed with an example of printing machine control simulation.
