摘要
对用于航空发动机磨损在线监测的能谱数据处理方法进行了研究。介绍了基于同位素 X射线荧光法的滑油磨损在线监测系统的组成及工作原理 ,通过对所获得能谱数据进行平滑、剥谱、寻峰、峰净面积计算、浓度插值计算等处理 ,就可以实现杂质浓度的自动检测。文中提出了一种函数拟合寻峰方法 ,实验结果表明 ,这种方法具有算法简单、运算速度快等优点 。
An energy spectrum data processing method used for Aircraft Engine On-line Wear Monitor(AEOWM)is studied.This paper also introduces the structure and operating principle of AEOWM based on Isotope X-ray Fluorescence Method.In order to acquire impurity concentration of oil automatically,the energy spectrum data processing is needed,such as smooth,trip,peak-search,net peak area calculation,etc.A new peak-search method is presented.The test results proves that this method specially fits for on-line spectrum data processing because of its simplicity and high speed.
