摘 要
基于單片機的加油計量系統(tǒng)，是通過流量傳感器把流量信號轉(zhuǎn)換為脈沖信號，再把脈沖信號進行放大、整形等處理，使之變成標(biāo)準(zhǔn)的脈沖信號后再送入到單片機中，由單片機對脈沖進行記數(shù)、累加等工作，由此再綜合計算測出所加油的體積，并由單片機驅(qū)動LED數(shù)碼管顯示部分進行數(shù)字顯示，以實現(xiàn)一套完整的加油計量功能。本系統(tǒng)同樣適用于對一般的液體流量計量，擁有較強的通用性和較高的擴展性。
Abstract
Base on micro-controller topping-up measure system, is acting as the rate of flow signal conversion to the impulse signal by means of the rate of flow sensor, causing it turn into the criterion impulse signal afterwards to carry up the micro-controller again, and bears in mind work such as figure and accumulating and so on to the impulse through the micro-controller, the bulk lubricated is fathomed out in synthetically calculation more thus to handles such as enlarges the impulse signal and plastic and so on again , and displaying partly carrying on the DD digital display through micro-controller drive LED's nixie light , in order to achieve one suit of integrated topping-up measure meritorious service capacity . That this system is applicable equally to calculates to the ordinary liquid rate of flow, and haves more powerful commonality and the taller augment ability.
