The application programs possess multitask function , and can transport various basic files at the same time , can realize monitoring of remote screen , sending system message and recording basic operations of the system 這種應(yīng)用程序具有支持多任務(wù)的功能,可以在進行基本文件操作的同時實現(xiàn)遠程屏幕監(jiān)控,發(fā)送系統(tǒng)消息,記錄系統(tǒng)的基本操作。
The main achievements are as follows : based on the research of principles and methods of data collection and processing , the dissertation put forward using vxd to accomplish break response of hardware and utilizing control principle of dma to realize data transfer of high speed . so the dissertation conquers the defect of bad real - time characteristic of windows because of multitask function and message mapping and accomplish real - time of collection and analysis . and the dissertation develops the system of signal collection and analysis to test vibration and noise and analyze structure dynamics 主要工作及創(chuàng)造性成果如下:提出了利用vxd來實現(xiàn)硬件中斷響應(yīng),并運用dma控制原理實現(xiàn)了高速數(shù)據(jù)傳輸,克服了windows操作系統(tǒng)多任務(wù)功能及消息映射機制所帶來的實時性差的弊端,從而實現(xiàn)采集和分析的實時性,開發(fā)出適用于振動噪聲測試、結(jié)構(gòu)動力學(xué)分析和機械在線檢測的信號采集分析系統(tǒng)。
