电磁流量计设计论文

编号毕业论文题 目电磁流量计设计摘要本课题讨论的容主要是利用电磁感应原理对各种液体如石油、水等的流量进行检测与控制。主要由流量传感器采集流量信号，然后经过 A/D 转换器将连续的模拟信号转化为离散信号后传给单片机运算，单片机在软件系统的控制下，根据预先的设置和预期的控制要求，将控制命令发送到步进电机，然后通过步进电机来精确控制阀门的开关,实现对流量的精确控制，并通过显示单元实时显示。在设计过程中，从总体方案、单元电路、元器件选择和设计等都进行了细致的介绍。关键词：流量计 电磁感应 A/D转换器 AbstractThe content of this research is mainly using the electromagnetic induction principle to all kinds of liquid such as oil, water flow test and control.Mainly by flow sensor to collect traffic signal, and then, after A/D converter will be continuous analog signal into A discrete signal to the single chip microcomputer after operation, under the control of single-chip microcomputer in the software system, according to the control requirements of setting and expected in advance, will control commands sent to the stepper motor, and then through the stepper motor to precisely control the switch of the valve, realize the precise control of traffic, and through the display unit in real time.In the design process, from the overall plan, the unit circuit, components selection and design and so on all has carried on the detailed introduction.Keywords:Flowmeter Electromagnetic induction A/D converter 目 录摘 要..............................................................IABSTRACT...........................................................II第一章 绪论........................................................11.1 课题讨论背景...................................................11.2 课题容.........................................................11.3 讨论意义.......................................................1第二章 系统总体设计....................
