基于WiFi技术的三相交流负载电路实验教学
|
摘要
传统的三相交流负载电路实验教学采用手工连接电路、手工改变电路负载连接状态的方法,时间花费多,也存在用电操作安全的问题。通过WiFi技术,可以实现对电路设备的无身体接触控制。在实验室已有电工学实验箱的基础上,提出了基于WiFi技术的三相交流负载电路实验装备改造方案。以变易学习理论为指导,介绍了通过该实验装备对三相负载电路的有关特征进行变易以促进学生学习。
The manual method is adopted to connect the circuit and change the way of circuit load connection state for the traditional three-phase AC load circuit experimental teaching,which costs a lot of time and brings about the worry about the safety of electricity operation.Through the WiFi technology,the non-physical contact control of the circuit equipment can be realized.On the basis of the electrotechnics experiment box in the laboratory,the reform scheme for the experimental equipment of the three-phase AC load circuit based on the WiFi technology is proposed.By taking the variation learning theory as guidance,the variation of characteristics of the three-phase load circuit through the experimental equipment is introduced and students' learning is promoted.
