摘要:可编程序控制器(PLC)是使用最多的微机化的工业控制设备,现在PLC课程几乎在各个工科大学都有开设。PLC实验课要使用各种被控对象的硬件,通过计算机来模拟PLC被控对象,可以用较少的成本和多样的程序,来丰富实验课的内容,增强教学效果。组态软件是在计算机上使用的控制监控软件,画面生成以及图形对象和PLC通信的实现都很方便,是用来模拟PLC被控对象的最佳软件。作者用国产组态软件“组态王”对电梯建立虚拟模型并用两种方式进行模拟
1.用组态软件对5层电梯进行模拟并编写PLC控制程序,计算机通过串行通信方式与PLC交换信息,用PLC控制“虚拟”电梯。虚拟电梯的轿厢和门通过软件中命令语言编写的程序执行相应的动作,用画面中的指示灯显示来自 PLC的各种信息。
2.用组态软件实现对5层电梯控制系统的纯软件仿真。这种仿真方式不是用PLC程序来实现对虚拟电梯的控制,而是通过组态软件中命令语言编写的程序实现电梯控制,对电梯本身的模拟也是由组态软件实现的。这种仿真控制系统可以帮学生更透彻地了解和使用组态软件,对于教学有较大的实际价值。5968

The design of multi-layer virtual elevator model based on configuration software
Abstract: Programmable Logic Controller (PLC) is the most consumption of computerized industrial controlling device. The courses on PLC are now offered in almost all technological universities. PLC experimental classes need controlled equipments made up of hardware, simulating the controlled plant of PLC by computer can enrich the content of experimental class and enhance the teaching effect with a cheaper and persified process.
Configuration software is a computer monitoring software for control system, which is easy to generate the graphic and communicate with PLC. It is the best software to simulate the controlled plants. Using "King View", a configuration software, the author simulated an elevator in two ways:
1.The simulation of a five-storey elevator with the configuration software. With the "virtual" controlling programs written for PLC, the information exchange between the computer and the PLC has been implemented through the serial communication, and then, the elevator is controlled by the PLC. By software command language program, the virtual elevator car and the door execute an action accordingly, and the indicator in screen displays a variety of information from the PLC.
2. The pure software simulation of five-storey elevator control system with the configuration software. This simulation uses the command languages of the software, with which the elevator is also simulated, to control the virtual elevator instead of user's PLC programs. Such simulation control system can help students to understand deeply and use configuration software better; it has great value in the teaching.
