安卓测量程序及其不确定度

摘要

设计安卓测量程序,尝试发挥安卓设备的工业应用潜力.安卓测量程序能计算非正弦和三相不对称功率.在MATLAB上生成有谐波及不平衡条件下的三相工频电压电流信号并计算标准参数,同时利用MATLAB采样三相工频电压电流信号,将采样数据AD变换后通过WiFi传输给安卓测量程序.对比分析MATLAB计算出的标准参数和安卓测量程序的计算结果,评定安卓测量程序不确定度.%An Android measurement procedure is designed to give play to the potential of Android devices in industrial application.The Android measurement program can calculate non-sinusoidal and 3-phase unbalanced power.MATLAB is used to generate 3-phase power frequency voltage and current signals with harmonic components under unbalanced conditions, and standard parameters are calculated.In the meanwhile, MATLAB is used to sample 3-phase power frequency voltage and current signals, and the sampled data goes through AD transformation and is transmitted to the Android measurement program via WiFi.The standard parameters calculated through MATLAB and the calculation results of the Android measurement program are compared and analyzed, and the uncertainty of the Android measurement program is assessed.
