摘要
基于高速数字化仪硬件设备,针对数字采集系统软件设计的关键技术从设备驱动程序、动态链接库接口函数封装、应用软件设计三个层次进行了详细阐述。采用VS2008,在Win7系统下设计了WDF驱动程序并实现了DMA传输;设计封装了操作设备的接口函数;用C#语言及多线程技术设计实现了多通道数据高速传输、实时显示及存储系统,实验测试结果稳定可靠。
Combined with the hardware equipment of digitizer, the key problems and resolutions in the development of software of high speed data acquisition and analysis system are discussed. It is discussed from three aspects-device driver,driver interface encapsulation and application software. Firstly, the basic frame and operational mechanism of WDF are analyzed thoroughly. Using VS2008, under Win7 system design WDF driver and implements the DMA transfer; design encapsulates the interface functions to operate the equipment; using C# language and multi-threaded design and implementation of the multi-channel high-speed data transmission, real-time display and storage system.Experiments show that the system is stability.
