| Abstract: | This paper introduces the principle of the equal-precision frequency measurement method and the traditional method,analyzes the difference between the two,and applies the method of equal-precision frequency measurement to measure the rotational speed. The way to build a rotational speed measurement system in software and hardware is given. The experimental results show that the system has a high measuring accuracy and anti-interference ability,and it is applicable to the power monitoring and control system. |
