無線傳感器在高速公路

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