以C8051f020為核心處理器，設計無線傳感器網絡數據采集系統。系統采用SZ05-ADV型無線通訊模塊組建Zigbee無線網絡，結合嵌入式系統的軟硬件技術，完成終端節點的8路傳感器信號的數據采集。現場8路信號通過前端處理后，分別送入C8051f020的12位A/D轉換器進行轉換。經過精確處理、存儲后的現場數據，通過Zigbee無線網絡傳送到上位機，系統可達到汽車試驗中無線測試的目的。
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.
