家庭照明智能遥控器开关设计

Design of Home lighting intelligent remote control switch

随着人们对照明的高效控制和功能多样化的要求不断提升,智能照明系统应运而生。选择利用红外遥控系统来控制被控对象,整个系统由发射电路和接收电路两个部分组成。发射部分包括键盘矩阵、编码调制、单片机系统、红外发送器;接收部分包括红外光接收、解调、继电器、解码电路、三极管。调试表明所设计电路具有使用方便、性能可靠等优点。

With the rapid requirement of efficient lighting and function diversification for lighting, intelligent lighting system has been developed. The option of using infrared remote control system to control the controlled object, the entire system consists of transmitting circuit and the receiving circuit. transmitting circuit includes a keyboard matrix, coded modulation, system on chip and an infrared LED transmitter. LED infrared light receiving portion comprises a infrared receiver, demodulator, decoding circuit and transistor. Experimental results show that the circuit has the advantages of convenient operation and reliable performance.
