基于红外反射式光电传感器的电机测速
Infrared reflective optical sensor based on motor speed
本文介绍了用红外反射式光电传感器RPR220测电机转速，传感器对装在电机转轴上码盘的黑白色标记检测，电机转动时传感器输出一系列脉冲，通过电压比较环节与去毛刺处理环节，得到一系列比较好的方波脉冲。以单片机ATmega16为主控制器，对输入脉冲进行处理，并得出转速并进行显示。
his article describes the infrared reflective photoelectric sensor RPR220 measuring motor speed, Chuan Ganqi of the shaft mounted Zaidian Ji Shang code Pan black and white markers, Dianjizhuandong O’clock sensor Shu Chu Yi Jilie Mai Chong, Tong Guo voltage comparison and de-burr Chu Li Huan Jie link, obtains series of good square wave pulse. With ATmega16 microcontroller-based controller for processing the input pulse, and draw speed and display.
