应用数据采集卡结合实际工程,研究了Windows环境下实现高速数据采集与处理问题。Windows环境为多线程系统,具有不确定性,基本上不可能用软件实现精确数据采集。因此主要从硬件角度,结合软件设计了一套Win-dows环境下的高速数据采集与处理系统。应用结果显示,该系统的设计思想在其它方面的应用也有借鉴意义。 Application of data acquisition card combined with the actual project to study the Windows environment to achieve high-speed data acquisition and processing issues. Windows environment for multi-threaded system, with the uncertainty, it is basically impossible to achieve precise data acquisition software. Therefore, mainly from the hardware point of view, combined with software design a set of Win-dows environment, high-speed data acquisition and processing system. Application results show that the system design ideas in other aspects of the application also have reference.
