基于單片機(jī)的加油計(jì)量系統(tǒng)

摘 要

基于單片機(jī)的加油計(jì)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(jìn)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(jī)中，由單片機(jī)對脈沖進(jìn)行記數(shù)、累加等工作，由此再綜合計(jì)算測出所加油的體積，并由單片機(jī)驅(qū)動LED數(shù)碼管顯示部分進(jìn)行數(shù)字顯示，以實(shí)現(xiàn)一套完整的加油計(jì)量功能。本系統(tǒng)同樣適用于對一般的液體流量計(jì)量，擁有較強(qiáng)的通用性和較高的擴(kuò)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.
