| 摘 要： | 论述了均值变点分析理论的原理、分析方法，并将其应用于输油管道dTs监测数据分析与处理中，采用变点的离散模型机最小二二乘估计对多变点数据进行变点估计，计算出了变点的跳跃度。通过试验分析表明，该方法能够准确的定位变点的大小、位置和数量，能有效地应用于管道监测数据处理应用中。

| Abstract: | On the point of theory and analysis method of mean value change, it was applied in the processing of DTS monitoring data of oil pipeline. The model machine of least squares estimation change - point was used in multivariate data and in calculating the jump change point. Its test indicated that this method can present accurately the proportion, the position and the quantity of change point in pipeline monitoring data processing. |
