新型录像机的红外遥控接收电路通常由一片专用集成器件和少量外围元件组成。该接收电路的功能主要是,接收遥控发射器发出的红外光信号,将红外光信号转换为电信号并予以放大、限幅,再通过解调(检波)电路检出编码指令脉冲,整形后送入录像机微处理器的遥控指令输入端,使微处理器按红外遥控指令工作,向相应电路或机构发出命令,控制其动作,从而实现遥控功能。
New VCR infrared remote control receiver circuit usually consists of a dedicated integrated device and a small amount of peripheral components. The main function of the receiving circuit is to receive the infrared light signal from the remote transmitter, convert the infrared light signal into an electrical signal, amplify and limit it, and then detect the encoded command pulse through the demodulation (detection) circuit, Into the recorder microprocessor remote command input, the microprocessor according to infrared remote control instructions to the corresponding circuit or agency issued a command to control its movements, in order to achieve remote control.
