摘　　要：基于目前已经在石油输送管道中应用的SCADA系统将信息融合技术应用于管道泄漏检测与定位系统中;该方法应用管道泄漏时的多种特征信号,采用最优加权融合算法将多元信息综合处理,扩展了时间和空间上的检测范围,提高了泄漏检测系统的灵敏度和可靠性;在实验室用水泵和不锈钢管道组成的水循环系统进行了模拟实验,通过对比验证了信息融合检漏方法比单一检漏方法具有明显的优越性。According to the SCADA system which is used in oil pipeline, information fusion is applied in pipeline leakage detection and localization system. The model uses adaptive weighted fusion estimating method to deal with a variety of the characteristic signals of pipeline leakage integratedly. This method can extend the monitoring range for time domain and space domain. And it can raise the sensitivity and reliability of the leak detection system. We have experimented on the water circulating system which is composed of the water pump and the stainless steel pipeline in laboratory. Compared with the single method of leakage detection, information fusion technology has remarkable superiority.
