1、哈爾濱理工大學(xué)學(xué)士學(xué)位論文學(xué)士學(xué)位論文基于單片機(jī)的電機(jī)轉(zhuǎn)速測速系統(tǒng)的設(shè)計摘要在工程實踐中，經(jīng)常會遇到各種需要測量轉(zhuǎn)速的場合，測量轉(zhuǎn)速的方法分為模擬式和數(shù)字式兩種。模擬式采用測速發(fā)電機(jī)為檢測元件，得到的信號是模擬量。數(shù)字式通常采用光電編碼器，霍爾元件等為檢測元件，得到的信號是脈沖信號。隨著微型計算機(jī)的廣泛應(yīng)用，特別是高性能價格比的單片機(jī)的出現(xiàn)，轉(zhuǎn)速測量普遍采用以單片機(jī)為核心的數(shù)字式測量方法。本文便是運用AT89C51單片機(jī)控制的智能化轉(zhuǎn)速測量儀。電機(jī)在運行過程中，需要對其進(jìn)行監(jiān)控，轉(zhuǎn)速是一個必不可少的一個參數(shù)。本系統(tǒng)就是對電機(jī)轉(zhuǎn)速進(jìn)行測量，并
2、可以和PC機(jī)進(jìn)行通信，顯示電機(jī)的轉(zhuǎn)速，并觀察電機(jī)運行的基本狀況。本設(shè)計主要用AT89C51作為控制核心，由霍爾傳感器、LED數(shù)碼顯像管、HIN232CPE電平轉(zhuǎn)換、及RS232構(gòu)成。詳細(xì)介紹了單片機(jī)的測量轉(zhuǎn)速系統(tǒng)及PC機(jī)與單片機(jī)之間的串行通訊。充分發(fā)揮了單片機(jī)的性能。本文重點是測量速度并顯示在5位LED數(shù)碼管上。其優(yōu)點硬件是電路簡單，軟件功能完善，測量速度快、精度高、控制系統(tǒng)可靠，性價比較高等特點。關(guān)鍵詞MSC-51（單片機(jī)）；轉(zhuǎn)速；傳感器-II-哈爾濱理工大學(xué)學(xué)士學(xué)位論文[89C51basedonthespeedmeasurementsy
