以C8051F020為核心處理器，設(shè)計(jì)無線傳感器網(wǎng)絡(luò)數(shù)據(jù)采集系統(tǒng)。系統(tǒng)采用SZ05-adv型無線通訊模塊組建Zigbee無線網(wǎng)絡(luò)，結(jié)合嵌入式系統(tǒng)的軟硬件技術(shù)，完成終端節(jié)點(diǎn)的8路傳感器信號的數(shù)據(jù)采集。現(xiàn)場8路信號通過前端處理后，分別送入C8051F020的12位A/D轉(zhuǎn)換器進(jìn)行轉(zhuǎn)換。經(jīng)過精確處理、存儲(chǔ)后的現(xiàn)場數(shù)據(jù)，通過Zigbee無線網(wǎng)絡(luò)傳送到上位機(jī)，系統(tǒng)可達(dá)到汽車試驗(yàn)中無線測試的目的。
Abstract:
This paper designs a wireless sensor network system for data acquisition with C8051F020 as core processors.The system used SZ05-adv wireless communication module，set up a Zigbee wireless network， combined with hardware and software technologies of embedded systems，completed the end-node 8-locale sensor signal data acquisition.Eight locale signals were sent separately into the 12-bit ADC of C8051F020 for conversion through front treatment.After accurate processing and storage，the locale data was transmitted to the host computer through Zigbee wireless.The system achieves the purpose of wireless testing in vehicle trial.
MATLAB是一個(gè)非常好的用于測量，分析和可視化的數(shù)據(jù)，控制儀器，并建立測試系統(tǒng)。安捷倫信號和頻譜分析儀可讓您分析失真，虛假的，相位噪聲，用于2G到4G無線通信測量。這種Matlab下開發(fā)的高級數(shù)據(jù)可視化（adv）的應(yīng)用軟件，擴(kuò)展了安捷倫信號和頻譜分析儀的可視化功能，提供了四個(gè)不同的顯示格式：Analog advanced, Analog Plus, Waterfall,和Spectrogram。這些顯示使得更加容易捕獲間歇性信號。
