目前在许多学校的可编程序控制器(PLC)教学过程中,实验装置难以满足要求。随着计算机多媒体技术的发展,“模拟实验型”CAI课件在实践性教学过程中发挥着越来越重要的作用。我们用VB语言设计的“PLC仿真实验系统”可以弥补现有PLC实验设备的缺陷,丰富老师的教学手段。软件设计过程主要是用户界面的设计、事件过程代码和通用过程代码的编写。系统的用户界面友好,便于学生上机操作。在软件中设置了交互性功能,判断电路连接、用户程序是否有错,并能按错误类型给出提示信息,以便学生正确修改。
At present, in many schools, programmable logic controller (PLC) teaching process, the experimental device is difficult to meet the requirements. With the development of computer multimedia technology, CAI courseware “simulation experiment” plays more and more important role in practical teaching process. We use the VB language design “PLC simulation experiment system ” can make up for the shortcomings of the existing PLC experimental equipment, enrich the teacher’s teaching methods. Software design process is mainly the user interface design, event process code and general process code. System user-friendly interface for students to operate on the machine. In the software set interactive features to determine the circuit connection, the user program is wrong, and can be prompted to give the wrong type of information, so that students correct.
