摘要编号毕业论文题目电磁流量计设计摘要PAGEII摘要本课题研究的内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AbstractAbstractAbstractAbstractThecontentofthisresearchismainlyusingtheelectromagneticinductionprincipletoallkindsofliquidsuchasoil,waterflowtestandcontrol.Mainlybyflowsensortocollecttrafficsignal,andthen,afterA/DconverterwillbecontinuousanalogsignalintoAdiscretesignaltothesinglechipmicrocomputerafteroperation,underthecontrolofsingle-chipmicrocomputerinthesoftwaresystem,accordingtothecontrolrequirementsofsettingandexpectedinadvance,willcontrolcommandssenttothesteppermotor,andthenthroughthesteppermotortopreciselycontroltheswitchofthevalve,realizetheprecisecontroloftraffic,andthroughthedisplayunitinrealtime.Inthedesignprocess,fromtheoverallplan,theunitcircuit,componentsselectionanddesignandsoonallhascarriedonthedetailedintroduction.Keywords:FlowmeterElectromagneticinductionA/Dconverter淮安信息职业技术学院毕业设计论文目录目录TOC\o"1-3"\h\z\uHYPERLINK\l_Toc21586摘要PAGEREF_Toc21586IHYPERLINK\l_Toc21038AbstractPAGEREF_Toc21038IIHYPERLINK\l_Toc17752第一章绪论PAGEREF_Toc177521HYPERLINK\l_Toc263181.1课题研究背景PAGEREF_Toc263181HYPERLINK\l_Toc35831.2课题内容PAGEREF_Toc35831HYPERLINK\l_Toc164841.3研究意义PAGEREF_Toc164841HYPERLINK\l_Toc4415第二章系统总体设计PAGEREF_Toc44153HYPERLINK\l_Toc17262.1总体设计PAGEREF_Toc17263HYPERLINK\l_Toc198372.2主要元器件PAGEREF_Toc198373HYPERLINK\l_Toc9531第三章系统硬件电路的设计PAGEREF_Toc95315HYPERLINK\l_Toc299533.1传感器电路PAGEREF_Toc299535HYPERLINK\l_Toc122513.2信号处理电路PAGEREF_Toc122515HYPERLINK\l_Toc131203.3A/D转换电路PAGEREF_Toc131206HYPERLINK\l_Toc138003.4驱动电路PAGEREF_Toc138008HYPERLINK\l_Toc197983.5显示电路PAGEREF_Toc197989HYPERLINK\l_Toc59003.6键盘电路PAGEREF_Toc59009HYPERLINK
