| 摘 要： | 针对瓦斯监测中多传感器监测数据的融合问题,提出了一种多源数据自适应分批估计算法。利用各组传感器局部融合值与最终融合值的方差自适应地调节各组的权重,通过多步融合逐渐弱化误差较大传感器组对最终融合值的影响。仿真实验表明:相对于平均值法与分批估计算法,该算法能有效地提高数据融合精度,能够满足瓦斯监测对实时性和精确性的要求。

| Abstract: | Aimed at multi-sensor data fusion for gas monitoring,a multi-source data fusion algorithm based on adaptive theory and batch estimation algorithm is conducted.The variance of each group partial fusion value and the final fusion value is used to adjust the weight of each group adaptively.This algorithm can weaken the influence of the group with big error through multi-step fusion.The simulation experiment shows that this method can improve the precision of data fusion compared with the average value method a... |
