摘　　要：针对移动平均防脉冲干扰数字滤波算法不能完全消除大误差带来的影响,以及改进的防脉冲干扰平均值滤波算法使时间复杂度大大增加,算法时效性变差等问题,提出了带时间戳的移动平均防脉冲干扰数字滤波算法。该算法对每一个采样值均引入了时间戳,即每一个采样点是由2个信息来确定的,采样的先后时间顺序信息和按其大小在采样排序队列中的位置信息。试验结果表明,带时间戳的抗干扰算法明显改善了算法的时效性和抗干扰性,随着N的取值增大,算法的优越性更加明显。The moving average anti-pulse interference digital filtering algorithm cannot completely eliminate the effect caused by the maximum error. The improved anti-pulse interference average value filtering algorithm increases the complexity of time remarkably. The timeliness of algorithm becomes less desirable. Considering these problems, the timestamped moving average anti-pulse interference digital filtering algorithm was put forward. The algorithm in- troduces the time stamp to every sampling value. In other words, every sampling point is determined by two kinds of information, namely, the information of time sequence of sampling and the location information of the sampling or- dered queue according to the size. The experimental findings show that the timestamped anti-interference algorithm remarkably improves the timeliness and interference immunity of the algorithm. The superiority of the algorithm gets more remarkable with the increase of the value of N.
