Design of improved voltage detection extreme median filter algorithm

提出一种改进的极值中值滤波算法的检测方法。将标准的电压数值设定成坐标,确定直线方程,运用线性规划相关理论,确定有效数据范围;运用公式,确定电压最大范围,设置上限、下限电压;按照改进极值中值滤波算法的原理对数据进行过滤,保留满足条件的数据。在采集的电压数据值中,改进的极值中值滤波算法,删除了更多不符合条件的数据。改进的极值中值滤波算法在过滤数据时,更好的过滤了波动性大的电压数据,保留的数据方差波动性更小。

To improve the accuracy and stability of voltage detection data, an improved detection method of extreme median filtering algorithm is proposed. Firstly, the standard voltage values are set as coordinates to determine the linear equation, and the effective data range is determined by using the linear programming theory. Secondly, using the formula, the maximum voltage range is determined and the upper and lower voltage limits are set. Finally, the data are filtered according to the principle of the filtering algorithm, and the data satisfying the conditions are retained. More unqualified data are removed from the collected voltage data by the algorithm. When filtering data, the algorithm can better filter the voltage data with large volatility, and the variance of the retained data is less volatile.
