The rotational speed measurement system based on 51 SCM is discussed in this paper. The pulse signal of motor is collected by optoelectronic encoder to realize generation and reshaping of the pulse signal,as well as information output and display after processing by SCM. The speed of electrical machine can be controlled remotely. The initial speed upper limit is re?set by keyboard module. The sound and light alarm occurs when the speed is higher than the upper limit. The system has simple hardware circuit,high measuring accuracy,stable and reliable performance due to application of the SCM and photoelectric sen?sor. It is applicable to automatic control,automatic detection,rotary speed measurement and control.
