This system to A3144 hall sensor for speed signal collection， AT89C51 microcontroller as the main controller for speed measurement， using realtime LCD1602 LCD display, and through the buttons to speed settings and adjustments . The system has a frequency response fast, antiinterference ability, the use of pulse counting method to achieve a measure of speed, through the LCD accurate and directviewing showing motor speed value. Has the very good application value. Keywords: Singlechip microputer。Speed measurement 重慶文理學(xué)院本科生畢業(yè)論文 (設(shè)計(jì) ) 第 1 頁 共 22 頁 1 引言 在 生產(chǎn) 中，經(jīng)常會(huì)遇到各種需要測(cè)量轉(zhuǎn)速的場(chǎng)合。測(cè)量轉(zhuǎn)速的方法分為模擬式和數(shù)字式兩種。數(shù)字式通
