| 摘 要： | 选取工程应用中易于实现的数据融合方法进行分析研究,并以融合数据与数据真实值的偏差作为数据融合方法的稳定性判定依据,进行了三余度多源数据的数据融合仿真试验。试验结果表明,加权最小二乘法在数据融合时表现稳定,可替代常用的矩估计融合和中值融合,更有效地提高融合数据的精度。

| Abstract: | This paper selects the data fusion method which is easy to realize in the engineering application, and takes the deviation of the data and the real value of the data as the stability criterion of the data fusion method, and carries out the simulation test of the data fusion of the three redundancy and multiple source data. The test results show that the weighted least square method is used in the data fusion. The performance is stable, which can replace the commonly used moment estimation fusion and median fusion, and improve the accuracy of the fused data. |
