动态信号实时采集及处理的图形菜单式软件包

在振动信号的处理理论上提出一些新的方法和处理技巧，使在微机上快速、有效地实现成为可能。应用目前最有效的Ｃ语言及其编译系统ＢｏｒｌａｎｄＣ＋＋３．１，用面向对象的设计思想（ＯＯＰ技术）实现了从振动动态信号的数据采集、处理分析及结果图像显示输出等的完整过程，并在菜单设计技术、动态内存分配、热键过滤技术、系统自识别技术及二、三维图像绘制、输出等方面，取得了一定的突破和创新，使整个软件的功能得以实现，并具有操作简便，容错性好，提示信息丰富，数据交换兼容性好等特点。

A GRAPHIC MENU SOFTWARE PACKAGE ON SAMPLING AND PROCESSING OF DYNAMIC DATA

in this paper,a new software system used for Dynamic Data Acquisition and Processing (DAP) has been developed.All its functions are based on Fast Fourier's Transform (FFT), and all operations of function procedures are selected by graphic pull-down menu or hot-key with ease.Apart from common spectral analyses such as: cross-power spectral density(Gxy), auto-power spectral density (Gxx), FFT, inversed FFT, wave filter etc., many new techniques are also provided listed as, indefinite integration by means of FFT method,acurate timing of sampling, dynamic memory allocation,two or three dimensional graphics drawing and outputing, system self recongnization etc.The practical example shows that the system has functions of high executing speed, a few memory occupied, effective function procedure, and great ability to popularize and extend.
