摘要
介绍了以单片微型机控制的CCD(电荷耦合器件)随动系统。该系统采用AT89C51单片机作为控制核心,ADC0804与单片机采用从主模式,由单片机读取ADC0804的转换结果,经处理后的数字信号经单片机处理后送入步进电机驱动,驱动步进电机,使其进行方位随动。实际应用表明,该系统具有可靠性较高、稳定性能好、性价比高等特点。
A CCD servo system based on SCM control is introduced. The system adopts AT89C51 chip as its control core, and ADC0804 and AT89C51 both adopt host pattern, the transformed result is fetched from ADC0804. The processed digital signal sent to steped electric motor drive, to drive steped electric motor, so that it follows the azimuth. Actual application indicates high reliability and stability, the system has good performance/cost.
