介紹了基于單片機航空交流電參數(shù)測試儀的系統(tǒng)設(shè)計。以Silicon Labs公司的C8051F005單片機為核心設(shè)計出數(shù)據(jù)采集板，通過RS-232串口與上位機通訊。運用Lab Windows/CVI編寫的上位機軟件實現(xiàn)信號的檢測以及波形和數(shù)據(jù)的顯示，給出了測試儀硬件電路的組成和軟件流程圖。本系統(tǒng)具有硬件結(jié)構(gòu)簡單、容易實現(xiàn)和成本低等特點，在實際應(yīng)用中其穩(wěn)定性、精確性均能滿足客戶要求。

Abstract:

 The design of aeronautics AC parameters tester based on the single-chip is introduced.The core component of data acquisition board is C8051F005 single chip of Silicon Labs Company,and communication with PC through RS-232. The signal processing software programmed with LabWindows/CVI can be used successfully to fulfill inspection of signal and display of the waveform and data. The hardware and software configuration of test instrument are provided.The hardware of the system is simple, and can be easily realized.The stability and precision of the measurement instrument are enough to meet the requirements.
