| 摘 要： | 以STC89C52单片机作为整个系统的控制核心,采用光电检测追光模式设计了一个自动追光系统.在光电检测追踪模式下,光电检测部分采用光敏三极管3DU5C作为光电传感器对光源信号进行采样,通过光敏三极管的比较电路来判断光源的方位,并通过A/D转换芯片ADC0809转换成数字信号,单片机采用L298N驱动电路驱动直流电机以控制小车,从而达到了自动追踪光源的目的.

| Abstract: | A light source automatic tracking system using STC89C52 MCU as the control core is designed.In the tracking mode of optical detection,a phototransistor 3DU5C is taken as photoelectric sensor to collect light signal,the light-source position is determined by comparison phototransistor circuit,and the signal is converted into digital signal by A/D conversion chip ADC0809.The digital signal is accepted by MCS-51 microprocessor which drives DC motor to control the car,so as to achieve the purpose of automatic tracking light source. |
