基于单片机的加油计量系统
摘 要
基于单片机的加油计量系统，是通过流量传感器把流量信号转换为脉冲信号，再把脉冲信号进行放大、整形等处理，使之变成标准的脉冲信号后再送入到单片机中，由单片机对脉冲进行记数、累加等工作，由此再综合计算测出所加油的体积，并由单片机驱动LED数码管显示部分进行数字显示，以实现一套完整的加油计量功能。本系统同样适用于对一般的液体流量计量，拥有较强的通用性和较高的扩展性。
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.
