無(wú)線傳感器在高速公路

1、無(wú)線傳感器網(wǎng)絡(luò)在高速公路研究摘要課題主要研究無(wú)線傳感器網(wǎng)絡(luò)技術(shù)再高速公路交通管理中的應(yīng)用。充分利用無(wú)線傳感器 網(wǎng)絡(luò)的分布性、靈活性、動(dòng)態(tài)性及無(wú)線通信等特點(diǎn)，通過(guò)在高速公路上等距離的布置無(wú)線傳 感器固定節(jié)點(diǎn)，實(shí)現(xiàn)對(duì)車載節(jié)點(diǎn)的速度檢測(cè)、路況檢測(cè)、路燈管理和信息的無(wú)線傳輸?shù)裙δ堋?智能化的管理對(duì)高速公路的建設(shè)和運(yùn)營(yíng)具有非常重要的意義，同時(shí)也將產(chǎn)生巨大的經(jīng)濟(jì)效益 和社會(huì)效益。關(guān)鍵字 傳感器；網(wǎng)絡(luò)節(jié)點(diǎn)；速度檢測(cè)；路況檢測(cè)；路燈自動(dòng)管理；高速公路管
