基于小范圍無線通信協(xié)議的嵌入式產(chǎn)品
以藍牙為代表的小范圍無線接入?yún)f(xié)議與嵌入式系統(tǒng)的結(jié)合,必將推動嵌入式系統(tǒng)的廣泛應(yīng)用。近來,基于這些協(xié)議的嵌入式產(chǎn)品層出不窮,包括各種電話系統(tǒng)、無線公文包、各類數(shù)字電子設(shè)備以及在電子商務(wù)中的應(yīng)用。這些產(chǎn)品以其微型化和低成本的特點為它們在家庭和辦公室自動化、電子商務(wù)、工業(yè)控制、智能化建筑物和各種特殊場合的應(yīng)用開辟了廣闊的前景。
東南大學(xué)移動通信國家重點實驗室以及依托實驗室建立的南京東大移動互聯(lián)技術(shù)有限公司,從1998年開始跟蹤藍牙技術(shù),在香港特區(qū)政府創(chuàng)新科技基金、江蘇省"十五"重大科技攻關(guān)以及國家"十五"科技攻關(guān)的資助下,先后設(shè)計和研制了多種基于藍牙技術(shù)的嵌入式產(chǎn)品。其中包括符合Bluetooth V1.1標準的嵌入式PSTN網(wǎng)關(guān)和語音終端。它們基于藍牙"三合一電話"應(yīng)用模型,選用了中國科學(xué)院凱思昊鵬軟件技術(shù)工程有限公司提供的Hopen OS作為嵌入式開發(fā)的軟件平臺,選用華邦的W90221作為硬件平臺。語音終端能通過PSTN網(wǎng)關(guān)以無線的方式接入到PSTN網(wǎng)絡(luò)中,實現(xiàn)和PSTN網(wǎng)用戶的互通。還有符合Bluetooth V1.1標準的嵌入式局域網(wǎng)接入點,它基于藍牙"局域網(wǎng)接入"應(yīng)用模型,選用嵌入式Linux操作系統(tǒng)作為軟件平臺,選用Motorola公司的CodeFire 5272作為硬件平臺。通過該接入點,終端用戶可以自由地接入到Internet,可以同時支持多個終端用戶連接到Internet。其它一些嵌入式產(chǎn)品包括智能多媒體家庭網(wǎng)關(guān)、遠程抄表系統(tǒng)、信息家電等等。
結(jié) 語
以上重點介紹了嵌入式系統(tǒng)的特點、嵌入式產(chǎn)品的開發(fā)和應(yīng)用。我們在開發(fā)過程中體會到:嵌入式系統(tǒng)開發(fā)和以前從事的開發(fā)工作實質(zhì)上并無區(qū)別,唯*改變的是每個硬件平臺都是獨特的,這一個不同點導(dǎo)致了許多附加的開發(fā)復(fù)雜性,因而,在嵌入式開發(fā)過程中要格外注意軟件創(chuàng)建過程;而且,在開發(fā)嵌入式產(chǎn)品之前要對選用的嵌入式硬件平臺有較多的了解,具備相應(yīng)的硬件知識,和硬件工程師密切配合;在選用嵌入式操作系統(tǒng)和硬件平臺時要根據(jù)所要開發(fā)的應(yīng)用的需要以及成本等方面的考慮選擇合適的系統(tǒng)和平臺。
在科技快速發(fā)展的今天,嵌入式產(chǎn)品將會越來越多地被廣泛應(yīng)用。我們相信,只要遵循嵌入式產(chǎn)品的開發(fā)規(guī)律,適應(yīng)市場的需求,就一定能開發(fā)出越來越多的嵌入式產(chǎn)品。
