摘要
海量数据处理不仅对电脑的配置要求很高,而且工作量巨大。基于图形化编程语言LABVIEW,设计并开发了一套海量数据处理分析系统。针对海量数据的特点,采取分段读取和写入,同时挑选特征点显示时域图等技术。即使在个人电脑上同样可以完成海量数据进行随机读取、线性谱以及功率谱密度分析等,并且可以无人值守批处理大量数据。系统还采用了LABVIEW的一些新特性———类与XControl技术,使得程序更加模块化与清晰。
Processing of mass data requires high computer＇s configuration and the tasks are overload.Based on LABVIEW,a graphical programming language,a data processing system for mass data is designed.For the features of mass data,the system will read or write data in sections and show time-domain graph with feature points.With the techniques above,the system can read the data randomly and calculate the linear spectrum and power spectral density even uses the personal computer.The system also can batch process large amounts of data when it is unattended.This system also takes the advantages of the object-oriented programming and XControl teconology to make the program more modular and clearer.
