摘要
根据地磁台站数据在地震预报研究中的应用特点,研究了地磁数据获取、处理和存储的规范和流程,并根据规范和流程,利用可视化交互数据语言(IDL)和DataMiner接口实现了一个地磁台站数据频谱分析处理系统。在系统中,采用先处理存储后读写显示的方案,降低了系统的耦合度,改善了显示效果,提高了用户的体验度。
Based on geomagnetic data for earthquake prediction, the process of application of geomagnetic data is studied. According to the process and specifications, the frequency spectrum analysis system of geomagnetic data based IDL and DataMiner is designed and implemented. Separating the data processing and the result displaying not only simplified the development of the system, but also improved the expansibility and maintainability of the system, and improved the display effect and the user experience.
