基于组件模型技术的地磁数据干扰抑制系统

Implement of geomagnetic electromagnetic interference reduction system based on component object model

地磁观测数据中的人工干扰抑制等预处理工作需要一套高效、便捷、交互性好的预处理系统。将基于Matlab的核心干扰识别和抑制算法以组件对象技术的形式提供给其他编程语言调用,在系统架构上采用Windows DNA架构,在界面的开发上采用微软成熟的MFC架构。同时,给出系统架构模型及关键技术实现。该系统在实际应用中取得良好效果。

Man-made electromagnetic noises have caused an increasingly serious disturbance to the geomagnetic observation data. The quality of produced geomagnetic observation data declined sharply. Therefore, an effective and user friendly data preprocesses system which deal with geomagnetic electromagnetic interference is developed. The system is base on Component Object Model and Windows DNA. Algorithm of interference reduction based on Matlab is provided via Component Object Model. MFC architecture is used to develop user interfaces. Architecture model of this system and key technologies are provided in this paper. This software system has achieved good result in practical.
