【摘要】:针对现有报警选择方法在实时性和精确性方面存在的不足,提出一种基于有向滑动时间窗的报警动态选择算法。依据历史关联结果的趋向特征,动态调整每个时间窗内报警抽取的概率,向历史关联强度高的时间窗分配更高的抽取概率,提高报警关联的效率和准确性。仿真结果表明,该算法在实时性上远高于报警全选方法和随机选择方法,在关联精度上优于随机选择方法。
[Abstract]:In view of the shortcomings of the existing alarm selection methods in real-time and accuracy, a dynamic alarm selection algorithm based on directional sliding time window is proposed, which is based on the trend characteristics of historical correlation results. Dynamically adjust the probability of alarm extraction in each time window, assign a higher extraction probability to the time window with high historical correlation intensity, and improve the efficiency and accuracy of alarm correlation. The simulation results show that, The algorithm is much better in real time than the full alarm selection method and random selection method, and the correlation accuracy is better than the random selection method.
