红外线是在人的正常视觉范围之外的光线，利用红外线可以进行信息的传输。红外线的常见用途之一就是近距离遥控，像许多家电，例如电视机，VCD机，空调等都是使用红外线的方式进行控制的。本设计要求采用红外信号的发送与接收组件，加上触发器电路以及大功率电子开关或继电气开关实现对家用电器的电源控制。在给定直流电源电压和交流电源电压条件下，设计并制作一个红外遥控开关。-Infrared light outside of the normal visual range, using infrared transmission of information. One of the common use of the infrared is close remote, like many home appliances, such as TV sets, VCD players, and air conditioning are using infrared control. The design requirements using infrared signals to send and receive components, plus the flip-flop circuits, and high-power electronic switch or step electrical switches enable the appliances power control. Given DC supply voltage and the AC power supply voltage conditions, design and production of an infrared remote control switch.
