EVC数据采集在植物蒸腾测定仪中的应用

The Application Of EVC Data Acquistion in Plant Sap Flow Measuring Instrument

介绍了一种以S3C2410处理器为核心的数据采集器的设计方案。利用ARM对微弱信号进行采集分析,在Windows CE环境下利用eMbedded visual C++(EVC)4.0应用程序编写数据采集与实时曲线显示运行界面,并通过实例说明其在植物蒸腾测定仪上的应用。该设计具有低功耗、低成本、体积小等特点,与监控PC机相比,极大地提高了监控的可靠性和实时性。

An embedded data collection implement design project which used S3C2410 microprocessor as the core is proposed in this paper. It used ARM to sample and analyze the weak singal,and adopted the way that uses eMbedded visualC＋＋4.0 on Windows operating system to realize the real-time curve in the system. The paper gives the example of its application in plant stem sap flow measuring instrument. The system features low power consumption,low cost,and small cubage. Compared with the PC formonitoring,the reliability and real-ime property of this system is greatly improved.
