1、西南交通大學(xué)碩士學(xué)位論文基于無(wú)線傳感器網(wǎng)絡(luò)的牽引數(shù)據(jù)采集與傳輸系統(tǒng)的研究姓名:朱晉梅申請(qǐng)學(xué)位級(jí)別:碩士專業(yè):電力電子與電力傳動(dòng)指導(dǎo)教師:郭世明2012-06-01西南交通大學(xué)碩士研究生學(xué)位論文第1頁(yè)摘要隨著我國(guó)高速鐵路和重載運(yùn)輸?shù)陌l(fā)展,對(duì)機(jī)車(chē)的牽引性能提出了更高的要求。機(jī)車(chē)的牽引性能是否達(dá)到了設(shè)計(jì)要求,需要通過(guò)牽引試驗(yàn)來(lái)驗(yàn)證,而機(jī)車(chē)的牽引試驗(yàn)則是由牽引動(dòng)力試驗(yàn)車(chē)完成的。牽引試驗(yàn)是對(duì)試驗(yàn)車(chē)的各項(xiàng)性能(牽引力、風(fēng)缸壓力、牽引電機(jī)電壓、電流等)進(jìn)行測(cè)試和傳輸,并對(duì)試驗(yàn)結(jié)果進(jìn)行分析驗(yàn)證,以便后期進(jìn)行改進(jìn)和正式投入生產(chǎn)使用。目前的牽引試驗(yàn)車(chē)的牽引數(shù)據(jù)采集與傳輸系統(tǒng),
2、雖然實(shí)現(xiàn)了機(jī)車(chē)和試驗(yàn)車(chē)之間的數(shù)據(jù)無(wú)線傳輸,但機(jī)車(chē)與試驗(yàn)車(chē)本身的數(shù)據(jù)采集系統(tǒng),還是通過(guò)有線方式實(shí)現(xiàn)數(shù)據(jù)的采集與傳輸,這導(dǎo)致線路接線繁瑣,容易斷線,造成數(shù)據(jù)丟失,影響了數(shù)據(jù)采集的可靠性。所以本文提出了采用無(wú)線傳感器網(wǎng)絡(luò)實(shí)現(xiàn)牽引數(shù)據(jù)的采集和傳輸,從而提高牽引試驗(yàn)的效率。在無(wú)線傳感器網(wǎng)絡(luò)中,ZigBee技術(shù)以其速率低、功耗小、頻段開(kāi)放和結(jié)構(gòu)簡(jiǎn)單等優(yōu)勢(shì)占據(jù)了主要地位,本文在分析研究ZigBee組網(wǎng)技術(shù)及其協(xié)議棧的基礎(chǔ)上,對(duì)比了幾種無(wú)線傳感器網(wǎng)絡(luò)解決方案,選擇片上系統(tǒng)方式,采用TI公司的CC2530芯片,針對(duì)試驗(yàn)機(jī)車(chē)的需要,設(shè)計(jì)了牽引數(shù)據(jù)采集與傳輸?shù)臒o(wú)線傳感器網(wǎng)絡(luò)。針
