Multitasking capabilityenables the performance of varioustasks simultaneously to furtherincrease wellsite efficiency 多任務功能支持不同任務的同時處理,從而進一步提高了井場效率。
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 主要工作及創造性成果如下:提出了利用vxd來實現硬件中斷響應,并運用dma控制原理實現了高速數據傳輸,克服了windows操作系統多任務功能及消息映射機制所帶來的實時性差的弊端,從而實現采集和分析的實時性,開發出適用于振動噪聲測試、結構動力學分析和機械在線檢測的信號采集分析系統。
