This exempts the bus stewards from the trouble of reporting stops along the route and facilitates the passengers who are not familiar with the route. In our country, there have been relevant documents about the design of stopreporting device. But from the whole, their designs have the deficiency of parative single function, and inability to make full use of the resources of Monolithic machine system to bring out the entire efficacy of the device in largest degree. This paper incorporating the technology of Monolithic machine, Pronunciation, temperaturemeasuring, radio data transmission and LCD, gives a new design which have not only the stopreporting function, but also the temperaturemeasuring and characterindication functions. Thus it realizes the basic arrive, no matter the routes change or not。 對(duì)于報(bào)站器的設(shè)計(jì)國(guó)內(nèi)已有相關(guān)的文獻(xiàn)評(píng)論,但是總的來(lái)說(shuō)以前的設(shè)計(jì),功能相對(duì)比較單一,無(wú)法充分利用單片機(jī)系統(tǒng)的資源,最大程度的發(fā)揮報(bào)站器的全部功效。 1216 周:完成剩余部分,焊接,調(diào)試電路板。 掌握一定的模電數(shù)電的基本概念 原理。 完成無(wú)線數(shù)據(jù)的接收和解析,并且通過(guò)語(yǔ)音芯片和揚(yáng)聲器播放站臺(tái)信息和其他信息。傳統(tǒng)的由乘務(wù)人員人工報(bào)站,因其效果太差和工作強(qiáng)度太大,在很多大城市已經(jīng)被淘汰。公交車自 動(dòng)報(bào)站器的設(shè)計(jì)主要是為了彌補(bǔ)改變傳統(tǒng)語(yǔ)音報(bào)站器必須有司機(jī)操控才能工作的落后方式,進(jìn)站、出站自動(dòng)播報(bào)站名及服務(wù)用語(yǔ),為市民提供更人性化,更完善的服務(wù) 。 供電電壓:直流+ 12V。進(jìn)度安排: 13 周:查閱資料,了解公交車報(bào)站系統(tǒng)的背景以及國(guó)內(nèi)外的現(xiàn)狀;了解組成本次設(shè)計(jì)的各個(gè)芯片的資料以及做好開題報(bào)告的準(zhǔn)備工作。 (論文 )的工作量要求 撰寫 15000 字論文 ① 實(shí)驗(yàn) (時(shí)數(shù) )*或?qū)嵙?xí) (天數(shù) ): 300 機(jī)時(shí) ② 圖紙 (幅面和張數(shù) )*: ③ 其他要求: 查閱資料不少于 10 份 指導(dǎo)教師簽名: 年 月 日 學(xué)生簽名: 年 月 日 系主任審批 : 年 月 日 說(shuō)明: 1 本表一式二份,一份由學(xué)生裝訂入冊(cè),一份教師自留 。本文則結(jié)合單片機(jī)技術(shù)、語(yǔ)音技術(shù)、測(cè)溫技術(shù)、無(wú)線數(shù)據(jù)傳輸技術(shù)和LCD 顯示技術(shù),不但發(fā)揮了報(bào)站器的報(bào)站功能,而且同時(shí)擁有測(cè)溫功能和漢字顯示功能。 at the same time, it have the function of prereporting stops function of reporting stops: the buses of the whole city can report stops where they: at a certain distance before the stop, it can automatically and accurately report the stops without the driver pushing the button. At the time of bringing convenience to the passengers, it also makes the driver more intent on their working, thus increasing the security of the traffic. Key words: pronunciation。而傳統(tǒng)的公交運(yùn)營(yíng)系統(tǒng)的裝備和管理模式較難達(dá)到這兩者的完美結(jié)合。 課題研究的背景及意義 當(dāng)前國(guó)內(nèi)主要大城市的公交車大都采用人工語(yǔ)音報(bào)站,即每到一站由司機(jī)或者乘務(wù)員按語(yǔ)音鍵來(lái)進(jìn)行報(bào)站,而車站的識(shí)別、語(yǔ)音的播放還要靠駕駛員控制,不僅增加了駕駛員的操作 ,
