【正文】 速表與光標(biāo)紙的距離控制在很近的范圍，測(cè)量十分不方便。 轉(zhuǎn)速測(cè)量的方法很多，測(cè)量?jī)x表的型式也多種多樣，其使用條件和測(cè)量精度也各不相同。在測(cè)量范圍和測(cè)量精度方面都有極大的提高。 選題目的和意義 隨著超大規(guī)模集成電 路技術(shù)的提高，尤其是單片機(jī)應(yīng)用技術(shù)以其功能強(qiáng)大，價(jià)格低廉的顯著特點(diǎn)，使全數(shù)字化測(cè)量轉(zhuǎn)速系統(tǒng)得以廣泛應(yīng)用。測(cè)量轉(zhuǎn)速的方法分為模擬式和數(shù)字式兩種。 關(guān)鍵詞：?jiǎn)纹瑱C(jī)；霍爾傳感器；轉(zhuǎn)速測(cè)量 重慶文理學(xué)院本科生畢業(yè)論文 (設(shè)計(jì) ) 英文摘要 Ⅱ Abstract In the production process, the motor speed is necessary for accurate measurements. 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.
