基本电气控制线路教学方法研究

Teaching Methods Based on Electrical Control Circuits

《电气控制与PLC应用技术》课程教学中发现，学生不会应用或举一反三应用基本电气控制线路去设计电路或设计能力欠佳，经调查，造成此现象的主要原因是学生对基本电气控制线路理解不透，设计时根据要求不知应用何种控制线路。采用启发式增加法和并列比较法教学方法后，学生对基本电气控制线路的来龙去脉比较清晰，能很清楚地说出各控制线路间的关系及相同点与不同点，能快速记住并掌握基本电气控制线路，能根据要求维修现场设备和快速设计电路。

We found in teaching ＂ Application of Electrical Control and PLC technology＂, students will not apply or draw application of basic electrical control circuit design capabilities to design circuits or poor, after investigation, the main cause of this phenomenon is the basic electrical control students Lines do not understand thoroughly, and design applications on request I do not know what kind of control lines. Heuristic method and the parallel increase in comparison teaching method, students on the ins and outs of basic electrical control circuit is relatively clear, can be very clearly stated the relationship be- tween the control lines and the similarities and differences, can quickly remember and master the basic e- lectrical eontrol cireuits, according to the requirements of the maintenance site and quickly design cir- cuits.
