基于WinDriver的数据采集系统的设备驱动程序研究

工业计算机断层扫描成像(Industrial Computed Tomography--简称工业CT)的图像分辨率要求越来越高、数据量急剧增加。因此，获取高分辨率、大容量的工业CT图像对数据采集提出了更高的要求。如何实时采集、存储这些庞大的数据是工业CT要解决的重要问题之一，这涉及到总线、采集与存储、设备驱动程序、系统级软件设计等关键技术。在工业CT中，设计数据采集系统的设备驱动程序是Windows编程中最复杂、最深奥的工作。设备驱动程序的设计是硬件开发过程中的重要环节，是硬件功能能够实现的保证，它不仅与所设计的硬件设备有关，而且涉及操作系统的内核。详细论述了WinDriver下数据采集系统的设备驱动程序设计与实现。

Research on device driver program of data acquisition based on WinDriver

In the system of industrial computed tomography (ICT), the amount of data acquisition, storage, transmission and handling by computer has been growing exponentially with the fast development of the technology of computer. So the demand of data acquisition and storage of ICT image is the base of getting image information and absolutely necessary for each system of ICT image processing systems. How to get and process the large image data is very important to the technology of ICT, which is associated with BUS technology, developing in the kernel model of operating systems and programming in the system level, etc. In fact, how to program a device driver in Windows is the most difficult and the abstruse work in Windows programming fields. The design and realization of device driver program of data acquisition system based on WinDriver is discussed.
