| 摘 要： | 发动机废气排放测试数据因受发动机工作状态的影响存在着一定的波动性和偶然性,因此在废气数据的测试中存在较大的误差.为此,提出了一种基于数据融合的废气数据分析统计方法.这种方法通过把发动机的某一运转状态下测试的多组数据值进行分批估计数据融合,可使得数据融合值更接近真实值,从而进一步提高测试系统的精确性.该算法在由LabVIEW语言编制的程序中得到了验证.

| Abstract: | The engine exhaust emission testing data may have wave properties and contingency, as it is affected by the engine working status. Thus there must be a big discrepancy in the exhaust emission testing data. For solving this problem a new analytic statistics method based on data fusion is put forward in this paper. Fuse and estimate the different testing data in batch under condition of setting the engine working at a certain status; it can be make the data fusion value much close to the real value. Then the accuracy of the testing system can be greatly improved. This arithmetic has been approved in LabVIEW language complication process. |
