摘要
电梯的PLC控制是PLC教学中的重要应用,为了让学生了解电梯PLC控制的控制流程,验证学生所编制的PLC程序的正确性,需要通过实验进行教学,但考虑到实验条件、经费和安全性的问题,因此利用计算机仿真软件来完成电梯的PLC控制实验。用Visual Basic 6.0设计PLC实验虚拟对象,通过PLC与计算机的通信就可以实现PLC一动作,实验虚拟对象就发生相应动作的效果。
The PLC of elevator is an important teaching content.In order for students to know the controlling process of PLC and examine the correctness of PLC programming,it is necessary to do experiment in the teaching.Considering the experiment condition,expenses and safety,computer simulation software is used to finish PLC experiment.Visual Basic 6.0 is used to design visual object of PLC experiment.The action of PLC may be realized through the communication of PLC and computer.The visual object of experiment may have the corresponding effect of action.
