摘要
转速是一种很常见的衡量标准，虽然生活中不是常用，但是跟每个人都息息相关。动力除了直接给予外就是通过间接方式获得，而最好的循环不断地提供动力的方式就是不断旋转来循环提供，这就间接表明了转速这一指标的重要性了。本文对转速测量进行了研究，设计的是基于单片机的转速测量与显示系统，目的是了解转速测量的原理及常见方式，同时也加深对单片机的理解和在转速测量上的应用。
转速的测量通常通过测量频率来间接的获得转速值，这是适用于频率较高的情形使用，当需测量的转速频率较低通过测周期所得的数据更准确。为了更好地适应测量的需求，使用综合两种方式优势的方法可以为测量转速提供便利。经过测试，本系统采用测频率来测量转速在0~1500r/min的范围能满足实际要求，在测低速时有些许误差。

Abstract
Speed is a very common measure, although not commonly used in life, but with everyone is closely related. Besides direct power is obtained through indirect means, and the best way to continuously provide power is to continuously rotate to provide power, which indirectly shows the importance of the indicator of rotation speed.This article has carried on the research to the speed measurement, the design is based on the single chip computer speed measurement and the display system, the purpose is to understand the speed measurement principle and the common way, simultaneously also deepens to the single chip computer understanding and in the speed measurement application.
The measurement of rotating speed usually obtains the value of rotating speed indirectly by measuring frequency, which is suitable for the case of higher frequency. When the frequency of rotating speed to be measured is lower, the data obtained through the measurement period is more accurate. In order to better adapt to the needs of measurement, the use of integrated advantages of the two methods can provide convenience for measuring speed. After testing, the system USES the measurement frequency to measure the speed in the range of 0~1500r/min can meet the actual requirements, there are some errors in the measurement of low speed.
