摘要
在应用中容易受阳光和照明光线等杂散光线的干扰。采用跟踪动态电平的平均值电路、适当的光学及机械结构、单片机解决这一问题 ,使光电型红外传感器在非接触转速测量中的抗扰能力和测量准确度都会有明显提高。在调速系统和机械振动位移系统中将有着广泛的应用。
Photoelectric infrared sensors are objects to the interference of sunlight and illumination light.Adop- ting average circuit,optical and mechanical structure and the singe chip processor,the problem is resolved,Thecapability of anti-interference and measurement accuracy are improved obviously in non-contact rotation speed measurement.The methods will have comprehensive use in speed governor and mechanical vibration displacement system.
