| 摘 要： | 利用多传感器的信息融合思想，提出分布式检测与决策融合方法进行长距离海底管线泄漏监测。试验水管和天然气／凝析油管线现场数据分析表明此算法不仅降低了误报警概率，且对流体在输送过程中动态变化具有稳健性。

| Abstract: | Based on the conception of multi-sensors infomlation fusion, a method for distributions detection and decision fusion of sub-sea pipelines leakage monitoring is presented. The effect of the method is studied considering the test pipe data and the field data of natural gas pipelines. It can reduce the alarm warning probability and help to stabilize the non-stationary operating situation of pipeline transport. |
