1、DesignandImplementationofvehiclemonitoringsystemofhazardousmaterialstransportationbasedonWSNADissertationSubmittedfortheDegreeofMasterCandidate：WangSongSupervisor：Prof.ZhaoXiangmoChang’anUniversity,Xi’an,China摘要隨著危險(xiǎn)品運(yùn)輸行業(yè)的快速發(fā)展，危險(xiǎn)品運(yùn)輸車(chē)輛側(cè)翻、碰撞、泄漏和爆炸等安全事故頻發(fā)，帶來(lái)了一系列社會(huì)問(wèn)題和環(huán)境問(wèn)題。構(gòu)建有
2、效的車(chē)載危險(xiǎn)品狀態(tài)實(shí)時(shí)監(jiān)測(cè)系統(tǒng)，對(duì)于保障運(yùn)輸安全、加強(qiáng)危險(xiǎn)品運(yùn)輸管理、事故預(yù)警及救援具有十分重要的意義?；谏鲜霰尘?，論文設(shè)計(jì)開(kāi)發(fā)了基于無(wú)線傳感網(wǎng)絡(luò)的車(chē)載危險(xiǎn)品狀態(tài)監(jiān)測(cè)系統(tǒng)，該系統(tǒng)采用基于無(wú)線傳感網(wǎng)絡(luò)的危險(xiǎn)品在途分層監(jiān)測(cè)體系架構(gòu)，將監(jiān)測(cè)系統(tǒng)分為分布式信息采集層、車(chē)載處理傳輸層和遠(yuǎn)程應(yīng)用層。論文設(shè)計(jì)并實(shí)現(xiàn)了基于ATmega1281和AT86RF230的無(wú)線傳感器節(jié)點(diǎn)硬件及相關(guān)軟件，并以此為基礎(chǔ)構(gòu)建了多傳感器分布式危險(xiǎn)品狀態(tài)信息采集平臺(tái)；對(duì)車(chē)載無(wú)線傳感網(wǎng)絡(luò)MAC層CSMA/CA機(jī)制的退避算法、RTS/CTS方式和睡眠機(jī)制進(jìn)行了分析與改進(jìn)，同
