题目：基于51单片机简易GPS定位系统的设计摘要：GPS是英文GlobalPositioningSystem（全球定位系统）的简称，中文简称为“球位系”。随着科学技术发展，应用十分广泛，成为了人们生活中不可或缺的一部分。同时因其具有全球覆盖以及精度高、定位速度快、实时性好、抗干扰能力强等特点，使其成为了迄今为止最好的定位导航系统。本论文详细介绍了采用STC12C5A60S2单片机、GPS接收模块、12864液晶显示模块等器件进行简易GPS定位系统设计。首先介绍了此系统的研究前景和不同设计方案的优缺点，具体阐述了系统的软件设计、硬件设计等。并结合硬件的特点，对GPS接收模块和STC12C5A60S2单片机之间串行通信实现的途径进行了分析，GPS模块发出数据经由串口接收，且把所需数据从中过滤获得，在经过相应处理后显示特定的数据，最终实现效果是可以在LCD显示屏准确显示出时间、日期和用户所在位置的经纬度、速度等多种数据信息。本文还通过硬件和软件调试以及实验仿真分析，进一步验证了此系统和可靠性、精确性。它是一台体积小巧、携带方便、可以独立使用的全天候实时的定位导航设备，具有非常强可扩展功能的实际应用价值。关键词：GPS；单片机；定位系统；12864液晶屏；STC12C5A60S2ABSTRACT：GPSistheshortnameoftheEnglishGlobalPositioningSystem(GPS)，theChinesenamereferredtoas"para-ball."Withthedevelopmentofscienceandtechnology，iswidelyused，ithasbecomeanindispensablepartofpeople'slives.Whileitsglobalcoverageandhighprecisionpositioningspeed，real-time，anti-interferenceabilityandothercharacteristics，makingitbyfarthebestnavigationsystem.ThisthesisintroducestheuseSTC12C5A60S2microcontroller，GPSreceivermodule，12864liquidcrystaldisplaymodulesandotherdevicessimpleGPSpositioningsystemdesign.Weintroducethissystemresearchprospectsandtheadvantagesanddisadvantagesofdifferentdesigns，specificallyaddressingsystemsoftwaredesign，hardwaredesign.Andthecombinationofhardwarefeatures，theGPSreceivermoduleandserialcommunicationpathwaysbetweenSTC12C5A60S2MCUanalyzed，GPSmodulesendsdataviatheserialporttoreceiveandobtaintherequireddatafromthefilter，afterappropriatetreatmentofspecificdisplaydata，andultimatelytheeffectcanbeaccuratelyshowthetime，dateandlocationofthelatitudeandlongitudeoftheuser，speedandotherdataontheLCDmonitor.Thisarticlealsopassthehardwareandsoftwaredebuggingandsimulationexperimentstofurthervalidatethesystemandreliabilityaccuracy.Itisacompact，easytocarry，canbeusedindependentlyoftheall-weatherreal-timepositioningandnavigationequipment，hasastrongpracticalvalueisveryscalablefunctionality.KEYWORDS:GPS;SCM;PositioningSystem;12864LCDScreen;STC12C5A60S2目录1绪论.....................................11.1课题背景及意义.....................................................11.2论文主要内容.......................................................22GPS定位系统方案设计.....................................................32.1GPS全球定位系统简介...............................................32.2GPS信号接收方案选择...............................................52.3GPS接收模块的研究.................................................52.4系统总体方案的设计.................................................63硬件电路设计............................................................83.1硬件电路总体结构...................................................83.2硬件电路功能设计介绍...............................................83.2.1STC12C5A60S2简介.............................................83.2.2SiRFStarIIGPS信号接收模块................................133.2.3LCD12864液晶显示模块介绍..........................
