摘要：

针对传统采用的较为繁琐且不准确的物理方式检测电机转速的状况,将ATmega16单片机加入进行控制计数,并辅以数码显示,使用光纤式光电开关的结构进行传感接收信号,再应用单片机采用测频法对光电开关输出脉冲信号的频率进行检则。本装置在降低测速器成本,提高测速稳定性及可靠性等方面有一定价值,而且可以达到一般工业测速的测量标准,具有广泛的前景。

Abstract: Specifically for improving the status that the electric motor rotation rate was determined by comparatively fussy and inaccurate physics way in tradition, the singlechip ATmega16 was used to control counting and digital display was used. The structure of the fiber-optical photoelectric switch was used to the sensor signal receipt, then the frequency of the output pulse signal of the photoelectric switch was determined with frequency measurement method and singlechip. The device has reduced the cost of the rate detector, and has improved the measurement stability and reliability. It can used as the fast measurement standard for general industry, thus it has broad prospect.
