摘　　要：针对传统的实时数据处理结果按方案优先级选优输出方法存在的缺陷,提出一种结合实时数据处理结果的精度进行实时动态选优的方法。该方法在每个数据处理周期将所有的数据结果与数据融合处理结果相比较,按照误差值大小对处理结果进行排序,若当前选择输出结果的误差值大于其他结果的误差值,可采用人机交互方式进行动态切换,选择其他精度高的结果输出。实际应用证明,该方法能有效避免当测量方案优先级高的数据处理结果精度差时其结果被选优输出的问题,提高了实时数据处理结果的精度。This paper proposes a realtime dynamic optimization method taking into consideration the data accuracy of the processing results to overcome the drawback of traditional optimization methods in output of realtime data pro-cessing results according to scheme priority. In each data processing cycle, all results are compared with fusion data and the processing results are sorted out by error value. If the error of the current selected output is greater than the others, it can use man-machine interaction for dynamic switch, selecting the higher accuracy result as output. Ap-plications show that the proposed method effectively avoids selection of a high priority result with low accuracy as the optimal output. As a result, the accuracy of realtime data processing is improved.
