基于D-S证据理论的机车润滑油信息融合处理技术研究

Research on Information Fusion Technique of Engine Lubricant Based on D-S Evidence Theory

介绍了Dempster-Shafer(D-S)证据理论及其主要特点,分析了多传感器信息融合处理技术的主要方法,提出应用光谱仪、铁量仪、颗粒计数器和分析式铁谱仪,监测机车润滑油油样多组数据,多组数据的信息融合结果可以作为判断机车的实际磨损情况依据.

The theory of Dempster-Shafer＇s evidence and its main characteristics are introduced in more detail,and the main method of information fusion of multi-sensor is analyzed in this paper. The method that multi-group data on oil sample of engine lubricant is inspected by means of spectrometer, iron debris monitor, particle counting and analytic ferrography is presented. The conclusion of information fusion on the data can be regarded as evidence to estimate the actual status of engine abrasion.
