《电力拖动》是高职电气自动化及应用电子专业很重要的一门专业课.这门课程知识程度掌握得好坏,直接影响维修电工基本技能的培养.传统教学往往理论与实际脱节,控制电路原理的讲解犹如纸上谈兵,不但学生难以理解记忆,而且测试与考核无法有效地实施.采用智能化教学不但能激发学生学习兴趣,帮助学生理解记忆,而且能将教、学、练有效地结合为一个整体,从而取得良好的教学效果.本文以"双重联锁正反转控制线路"的教学为例,系统地阐述了智能化教学实施的原理、程序流程、硬件的选择及接线、状态输入和单片机程序的编写.%The course of Electric Drive is a very important one in the major of electrical automation and Applied Electronics in higher vocational colleges. That the knowledge of this course is good or bad can directly influence the training of basic skills of maintenance electrician. A traditional teaching mode which makes theory secede from practice has been applied in teaching principle of control circuit, so it has had little effects and students can not understand it well and test and evaluation are not be well put into effect. Intelligent teaching can not only stimulate students' interest in learning and help them understand memory, but combine the teaching, learning, practice effectively as a whole so as to get good teaching effect. Taking a case study of the teaching of"double interlocking positive inversion control circuit", this paper will systematically expound the principles of the implementation of intelligent teaching, program flow, hardware selection and connection, the state input and the preparation of SCM program.
