摘　　要：用电阻、电容、晶体管和继电器等模拟元器件设计一种红外遥控开关,系统供电采用电容降压型直流稳压辅助电源;利用电容充放电时间的不同解决了开和关的问题。详细介绍各单元电路的工作原理,与数字式遥控开关相比,它具有结构简单、体积小、重量轻以及安全可靠等优点,可广泛应用于中、短距离电器设备的开关控制。该设计已在实验室得到使用,效果良好。An infrared remote control switch is designed with analog components sucu as sistors and so on,its power supply systems using capacitance DC buck regulator auxiliary power supply. Opening and shutting is resolved through the different time with capacitor charging and discharging. It introduces the work that the unit circuit theory in adeatil. Comparing with digital remote control switch, it is simple in structure, small size,light weight,as well as the advantages of safe and reliable,can be widely used in electrical equipment shortdistance switch control. It has been applied in the laboratory,and made good use of effects.
