【正文】 采用也將越來越普及。 公交車自動報站器的設(shè)計主要是為了彌補改變傳統(tǒng)語音報站器必須有司機操控才能工作的落后方式，進站、出站自動播報站名及服務(wù)用語，為市民提供更人性化，更完善的服務(wù) 。在聲學(xué)領(lǐng)域，微機技術(shù)與各種語音芯片相結(jié)合，即可完成語音的合成技術(shù)，使得汽車報站器的實現(xiàn)成為可能，從而為市民提供了更加人性化的服務(wù)。傳統(tǒng)由乘務(wù)人員人工報站，該方式因其效果太差和工作強度太大，在很多大城市已經(jīng)被淘汰。s misinformation or failed to report, created the passenger by mistake under or the mild chronic bloody vaginal discharge, has had the very greatly negative influence regarding the public transportation operation, could have very many nonessential influences to the , studies the public transportation automatic newspaper station system is extremely essential. This topic main research is based on at89C51， GPS— 9543LP， ISD1700S public transportation automatic newspaper station system front, System that uses longitude measured information and store the GPS module in singlechip microputer in the longitude of sites pare information on， uplink, is also a downward line, are able to determine accurately whether the same time, based on the text of the speech synthesis technology, truly automatic, accurate broadcast stations. 目錄 1 緒論 ...........................................................................................................................3 課題研究的背景及意義 ................................................................................3 報站器的動態(tài)發(fā)展趨勢 ................................................................................3 設(shè)計的主要目標任務(wù) ....................................................................................4 2 方案 ...........................................................................................................................5 3 系統(tǒng)器件選型 ...........................................................................................................6 AT89C51 的簡介 .............................................................................................6 主要性能 .....................................................................................................6 引腳功能說明 .............................................................................................7 GPS— 9543LP 定位模塊 ................................................................................9 ISD1700S 語音芯片 ......................................................................................10 4 系統(tǒng)硬件研究與設(shè)計 ..............................................................................................12 各部分電路 ...................................................................................................13 單片機的最小系統(tǒng) ....................................................................................13 JHD162A 液晶顯示電路 ............................................................................13 ISD1700S 音頻輸出電路及按鍵電路 ........................................................13 GPS 模塊接口電路 .....................................................................................13 5 系統(tǒng)軟件研究與設(shè)計 ..............................................................................................15 主程序流程圖 ................................................................................................15 語音模塊子程序 ............................................................................................17 JHD162A 液晶顯示子程序 ...........................................................................18 6 結(jié)論 ..........................................................................................................................19 參考文獻 ......................................................................................................................20 附錄 ..............................................................................................................................21
