红外遥控系统分为主机和遥控机，遥控机就是发射部分，用来发射对主机灯光的控制信号。主机相当于接收部分，用来接收主机对从机的控制信号。本系统的发射部分和接收部分都是由8051芯片搭建成的。发射部分由复位电路、晶振电路、按键、指示灯、红外发光管等构成。接收部分由接收芯片HS0038、复位电路、晶振电路、红外接收头等组成。-Infrared remote control system is divided into host and remote machine, remote machine is transmitting part of the light used to launch the control signal to the host. The host is equivalent to receiving part of the host to receive control signals from the machine. The system' s transmitter and receiver parts are built into the chip by 8051. Launched in part by the reset circuit, crystal oscillator circuit, keypad, light, infrared light-emitting tubes form. Received in part by the receiver chip HS0038, reset circuit, crystal oscillator circuit, infrared receiver top form.
