1、XX學(xué)院畢業(yè)設(shè)計(jì)(論文)摘要GPS是GlobalPositioningSystem的縮寫(xiě),即全球定位系統(tǒng)。其目的是在全球范圍內(nèi)對(duì)地面和空中目標(biāo)進(jìn)行準(zhǔn)確定位和監(jiān)測(cè)。本設(shè)計(jì)是基于AT89C51單片機(jī)來(lái)實(shí)現(xiàn)的簡(jiǎn)易GPS定位信息顯示系統(tǒng)。本控制系統(tǒng)主要完成接受數(shù)據(jù),時(shí)間顯示、經(jīng)度顯示、緯度顯示等常規(guī)功能。單片機(jī)與OEM板采用串口通信,由單片機(jī)接受GPS信息,對(duì)其解碼,再通過(guò)LED顯示信息。GPS的信息顯示是輪流顯示時(shí)間、經(jīng)度、緯度的。本文介紹使用GARMIN公司的GPS25-LVS系列OEM(OriginalEquipmentManufacturer)接收板及單片機(jī)實(shí)現(xiàn)實(shí)時(shí)時(shí)間、經(jīng)緯度等綜合信息顯示的
2、設(shè)計(jì)方法。通過(guò)對(duì)GPSOEM板和LED顯示模塊的研究,設(shè)計(jì)了GPS定位信息的采集與顯示系統(tǒng)。重點(diǎn)介紹了利用單片機(jī)89C51對(duì)GPSOEM板的控制來(lái)實(shí)現(xiàn)定位數(shù)據(jù)的采集與傳送,以及將定位數(shù)據(jù)傳送至液晶模塊進(jìn)行顯示的過(guò)程。實(shí)踐證明,該系統(tǒng)顯示的時(shí)間非常精確、定位精度高,能滿足一般應(yīng)用項(xiàng)目的使用,具有一定的實(shí)用價(jià)值。關(guān)鍵詞:?jiǎn)纹瑱C(jī);數(shù)據(jù)采集;定位信息;GPSOEM板;LED顯示--63--XX學(xué)院畢業(yè)設(shè)計(jì)(論文)AbstractGPSistheacronymforGlobalPositioningSystem,theGlobalPositioningSystem.Itspurposeisonaglob
