摘 要

單片機(jī)自從20世紀(jì)70年代問世以來，得到了快速發(fā)展。從早期的8位機(jī)到現(xiàn)在的32位機(jī)，其硬件資源和軟件資源不斷豐富與完善，它在工業(yè)控制、儀器儀表、信息通信等領(lǐng)域有著廣泛的應(yīng)用。本文討論了以AT89C51單片機(jī)為核心的電機(jī)轉(zhuǎn)速測量的硬件組成和軟件設(shè)計(jì)，并且詳細(xì)介紹了利用光電編碼器技術(shù)在電機(jī)轉(zhuǎn)速測量中的實(shí)現(xiàn)及應(yīng)用。系統(tǒng)將M法和T法相結(jié)合，對電機(jī)轉(zhuǎn)速進(jìn)行測量，最后通過實(shí)驗(yàn)進(jìn)行驗(yàn)證。

Microcomputer System
of Revolving speed Measure

Abstract
The Microcomputer has appeared since the 1970s，and getting the fast development. From earlier 8-bit to current 32-bit，and its hardware resource and software resource have enriched constantly and perfect. It has extensive application in the fields of industrial control，instrument and apparatus， information communication etc. Under microcomputer of AT89C51 as the core ，this paper discusses with electromotor of revolving speed measure of the hardware constitution and the software design ，and detailed introduction utilizes photoelectric encoder technology realization and application in the measurement of rotational speed of the electromotor.The system combine with the method of T and the method of M，and it is validated through the experiment finally.
Keywords： Microcomputer Photoelectric Encoder Measure
