洛阳理工学院毕业设计(论文)I基于单片机的GPS定位系统设计摘要GPS是英文GlobalPositioningSystem(全球定位系统)的简称。由于GPS技术所具有的全天候、高精度和自动测量的特点,作为先进的测量手段和新的生产力,已经融入了国民经济建设、国防建设和社会发展的各个应用领域。本次设计由于采用GPS模块(M-87),基于单片机AT89C51来实现GPS定位信息显示系统。所以本设计详细介绍了一种成本很低,操作简单的经济型GPS定位系统的设计方案。本方案基于51单片机,M-87,12864液晶显示屏的等硬件,应用C语言,可以完成GPS的信息提取,可以显示时间、经度、纬度等其他信息,使用基本的键盘控制操作等。这种设计可以精度高、体积小、连续导航。本设计主要是应用于个人驾车外出旅游,出租车定位等领域。关键词:单片机,HOLUXM-87,LCD洛阳理工学院毕业设计(论文)IIDesignofGPSpositioningsystembasedonsingle-chipcomputerABSTRACTAsGPStechnologywitharound-the-clock,highaccuracyautomaticmeasurementandcharacteristicsasadvancedmeasurementmethodsandnewproductiveforces,areintegratedintothenationaleconomicconstructionandnationaldefenseconstructionandsocialdevelopmentinvariousareasofapplication.ThedesignduetotheuseofGPSmodule(M-87),AT89C51basedonsingle-chipmicrocomputertoachieveGPSpositioninginformationdisplaysystem.Sothisdesigndetailstoalowcost,easyaffordableGPSpositioningsystemdesign.Thisscenarioisbasedon51singlechip,M-87,12864LCDscreen,hardware,clanguage,youcancompletetheGPSinformationextraction,youcandisplaythetime,otherinformationsuchaslongitude,latitude,usingbasickeyboardcontrolofoperations.Thisdesignmakeshighprecisionandsmallsize,continuousnavigation.Thisdesignisappliedtoindividualcartravel,taxilocationandsoon.KEYWORDS:SCM,HOLUXM-87,LCD洛阳理工学院毕业设计(论文)III目录前言................................................................................................1第1章GPS和相关软件的简介.......................................................21.1GPS简介...............................................................................21.1.1GPS定义......................................................................21.1.2GPS定位基本原理......................................................21.1.3GPS特点.....................................................................31.2HULUXM-87简介...............................................................41.2.1HULUXM-87参数.....................................................41.2.2通信处理.....................................................................41.2.3M-87协议....................................................................5第2章硬件电路设计.......................................................................82.1设计方案的选择...................................................................82.1.1方案一.........................................................................82.1.2方案二.........................................................................82.2AT89C51................................................................................92.2.1AT89C51简介..............................................................92.2.2管脚说明...................................................................102.2.3AT89C51芯片擦除....................................................112.3单片机与GPS接口电路....................................................122.3.1单片机与GPS的接口电路.......................................122.3.2GPS模块管脚说明....................................................122.3.3键盘部分......................................错误!未定义书签。2.4LCD液晶显示器.................................................................132.4.1LCD12864概述.........................................................132.4.2基本特性....................................................................132.4.3模块接口说明............................................................142.5电源部分.............................................................................16第3章系统软件设计.....................................................................18洛阳理工学院毕业设计(论文)IV3.1系统软件概述......................................................................183.2软件程序的编写..................................................................183.2.1初始化模块...............................................................193.2.2数据接收处理模块...................................................19第4章系统调试.............................................................................214.1硬件调试.............................................................................214.2软件调试.............................................................................214.3系统测试结果.....................................................................22结论................................................................................................24谢辞................................................................................................25参考文献..........................................................................................26附录..................................................................................................26外文资料翻译..................................................................................28洛阳理工学院毕业设计(论文)1前言针对中国交通现状而言,我想大家都不言而喻。其实我更想说的是上班不易,下班难,当然我这里说上班不易是你必须提前一个小时左右的时间去赶车或开车,下班时,你到家可能很困难。因为堵车在这个时段是很常见的,特别是那些开私家车的人对这种情况更加烦恼,不知道改怎么做,我想他们想的更多的是还是等政府制定政策,在开几条道路吧!在这之前还是默认接受这样的情况。我想这样的情况我们大可不必这样默认接受,我本次设计就是有这方面的启发。面临如今交通现状,特别是私家车日益增多,对交通便利的压力很大,GPS车载定位监控对于缓解交通拥堵现象还是很有一定的作用,这个定位监控能及时的把自己的位置显示出来,及时找到一条交通不拥堵的道路,让自己的能准时的去工作,准时的到家等等:当然这个设计不仅仅只有这样一些的特点,他们对于自己外出旅行业有很大的帮助,他能准确的识别道路,识别自己的方位等很多方面。本文首先介绍了GP
