基于小范圍無(wú)線通信協(xié)議的嵌入式產(chǎn)品
以藍(lán)牙為代表的小范圍無(wú)線接入?yún)f(xié)議與嵌入式系統(tǒng)的結(jié)合，必將推動(dòng)嵌入式系統(tǒng)的廣泛應(yīng)用。近來(lái)，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(wú)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(diǎn)為它們?cè)诩彝ズ娃k公室自動(dòng)化、電子商務(wù)、工業(yè)控制、智能化建筑物和各種特殊場(chǎng)合的應(yīng)用開辟了廣闊的前景。
東南大學(xué)移動(dòng)通信國(guó)家重點(diǎn)實(shí)驗(yàn)室以及依托實(shí)驗(yàn)室建立的南京東大移動(dòng)互聯(lián)技術(shù)有限公司，從1998年開始跟蹤藍(lán)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(guó)家"十五"科技攻關(guān)的資助下，先后設(shè)計(jì)和研制了多種基于藍(lán)牙技術(shù)的嵌入式產(chǎn)品。其中包括符合Bluetooth V1.1標(biāo)準(zhǔn)的嵌入式PSTN網(wǎng)關(guān)和語(yǔ)音終端。它們基于藍(lán)牙"三合一電話"應(yīng)用模型，選用了中國(guó)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(tái)，選用華邦的W90221作為硬件平臺(tái)。語(yǔ)音終端能通過(guò)PSTN網(wǎng)關(guān)以無(wú)線的方式接入到PSTN網(wǎng)絡(luò)中，實(shí)現(xiàn)和PSTN網(wǎng)用戶的互通。還有符合Bluetooth V1.1標(biāo)準(zhǔn)的嵌入式局域網(wǎng)接入點(diǎn)，它基于藍(lán)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(tái)，選用Motorola公司的CodeFire 5272作為硬件平臺(tái)。通過(guò)該接入點(diǎn)，終端用戶可以自由地接入到Internet，可以同時(shí)支持多個(gè)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(yuǎn)程抄表系統(tǒng)、信息家電等等。
結(jié) 語(yǔ)
以上重點(diǎn)介紹了嵌入式系統(tǒng)的特點(diǎn)、嵌入式產(chǎn)品的開發(fā)和應(yīng)用。我們?cè)陂_發(fā)過(guò)程中體會(huì)到：嵌入式系統(tǒng)開發(fā)和以前從事的開發(fā)工作實(shí)質(zhì)上并無(wú)區(qū)別，唯*改變的是每個(gè)硬件平臺(tái)都是獨(dú)特的，這一個(gè)不同點(diǎn)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(guò)程中要格外注意軟件創(chuàng)建過(guò)程；而且，在開發(fā)嵌入式產(chǎn)品之前要對(duì)選用的嵌入式硬件平臺(tái)有較多的了解，具備相應(yīng)的硬件知識(shí)，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(tái)時(shí)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(tái)。
在科技快速發(fā)展的今天，嵌入式產(chǎn)品將會(huì)越來(lái)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(chǎng)的需求，就一定能開發(fā)出越來(lái)越多的嵌入式產(chǎn)品。
