长春理工大学毕业设计编号________本科生毕业设计基于AVR单片机的风速测量仪设计DesignsbasedontheAVRmonolithicintegratedcircuit'swindspeedmeasuringinstrument2008年6月摘要在对气象学越加重视的今天，气象数据的采集更显重要。风速是气象数据中的一个重要的参数，对它的测量，将会极大的影响到气象预报的准确性。随着风力发电的快速发展，风速的测量也被日益重视起来。本文介绍了一种基于AVR单片机的风速仪的设计,它利用测量旋转体的转速测得风速。本设计中采用ATMAGE16单片机，并设计了集数据采集、显示、传输于一体的便携式风速采集系统，本设计的主要目的虽然为风速测量，但是当对外部传动部件做简单修改以后不仅可以应用在风速的测量当中，也可在转速测量控制，车辆行驶速度测定，流速流量测量等方面发挥借鉴作用。关键字：ATMEGA16单片机，风速仪，测周法与测频法AbstractAttachedmoreandmoreimportanceintoday'smeteorology,meteorologicaldatacollectionismoreimportant.Meteorologicaldatawindspeedisanimportantparameter,itsmeasurement,willgreatlyaffecttheaccuracyofweatherforecasting.Withtherapiddevelopmentofwindpower,windspeedmeasurementshavealsobeenincreasingattentiontothem.Inthispaper,amicrocontroller-basedAVRanemometerdesign,whichusesthespeedmeasurementofrotatingbodymeasuredwindspeed.ATMAGE16theuseofsingle-chipdesign,anddesignasetofdataacquisition,display,transmissionspeedinoneportableacquisitionsystem,themainpurposeofthisdesignalthoughthewindspeedmeasurement,butwhenpartsoftheexternaldriveafterdoingasimplemodificationcanbeappliednotonlyinwindspeedmeasurement,themeasurementcanalsobecontrolledinspeed,vehiclespeedmeasuredflowvelocitymeasurementfromtheroleplay.Keyword:ATMEGA16microcontroller,anemometer,measuredfrequency-weeklawandthelawPAGEI目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc232399533"第一章引言PAGEREF_Toc232399533\h1HYPERLINK\l"_Toc232399534"1.1风速测量装置概述PAGEREF_Toc232399534\h1HYPERLINK\l"_Toc232399535"1.2基于单片机设计风速测量仪的优点PAGEREF_Toc232399535\h1HYPERLINK\l"_Toc232399536"第二章设计原理PAGEREF_Toc232399536\h3HYPERLINK\l"_Toc232399537"2.1风速测量仪设计原理PAGEREF_Toc232399537\h3HYPERLINK\l"_Toc232399538"2.2风速测量仪模型PAGEREF_Toc232399538\h4HYPERLINK\l"_Toc232399539"第三章传感器的工作原理及实现方法PAGEREF_Toc232399539\h6HYPERLINK\l"_Toc232399540"3.1传感器工作原理PAGEREF_Toc232399540\h6HYPERLINK\l"_Toc232399541"3.2红外传感计数器的原理PAGEREF_Toc232399541\h7HYPERLINK\l"_Toc23
