【摘要】 本文充分利用高速通用串行总线(USB)所具有的传输速度快、支持热插拔、即插即用、易于扩展、占用的系统资源少等优点,将其与传统的数据采集技术相结合,设计实现了一种基于USB的集数据采集、处理、分析和显示为一体的数据采集系统。论文首先介绍了USB体系结构和数据流的相关内容,然后介绍了数据采集系统的设计。数据采集系统的设计包括系统的硬件设计和软件设计。在硬件设计部分,首先介绍了芯片CY7C68013A的性能特点,然后给出了USB与外部控制器接口模块、外部控制与数据采集模块、固件存储模块和电源模块的具体设计方案,并重点介绍了设计中应该注意的问题。软件设计包括USB接口控制器的固件设计、驱动程序开发和主机端应用程序开发三大部分。在系统软件设计部分,固件程序和驱动程序开发是设计中的重点,论文先从总体上介绍程序的设计思想及其层次结构,随后详细介绍了各层次程序的设计过程,并给出了程序流程图和部分源代码。驱动程序开发部分简单介绍了Windows驱动程序模型(WDM)和USB驱动程序的开发过程,接着介绍了WDM驱动程序安装时必需的INF文件和主机端应用程序的实现。固件程序设计的平台为Keil C51,驱动程序和应用程序设计的平台为Visual C++6.0,辅助工具为Numega公司的DriverStudi03.0和Win2000 DDK。在文章结尾,对本课题进行了总结,并对采集系统的功能扩展进行了展望。更多还原

【Abstract】 A new kind of Data Acquisition System is designed in this thesis, which is based on Universal Serial Bus (USB) technology with data acquisition, analysis and display together. The advanced performance of USB with highspeed, Hot Plug In, Plug and Play, easily to expand and engrossing less syetem resource is shown in the system.At first, the paper introduces the protocol of USB bus in brief, and then discusses the design of data acquisition system, which includes two segments such as hardware design and software design. In hardware design segment, the features of CY7C68013A are described firstly, and then the schemes of USB interface control module, USB and external controller interface module, firmware memory modules and power module are described in detail. The key points of the design which should be paid attention to are also explained. Software design also includes three parts, USB interface controller firmware design, USB driver development and application procedures.In the software design segment, firmware and driver design is the most important project of the system. First, the paper presents the idea and the structure of the program, and then introduces the firmware design and the flow chart of the firmware code in detail. In device’s driver segment, the principle of windows drivers module and the developing process of USB devices’ drivers are briefly described. In the last part, the INF file which is need to installation of WDM Driver is described in detail, and the realization of application program. Firmware was compiled with Keil C51, and the driver and application program with Visual C++6.0 and DriverStudio 3.0 assistant tools.In the end, the paper makes a conclusion of the project, and the foreground of USB application is explored.更多还原
