| 摘 要： | 基于组件对象模型(COM)的PC数据采集卡驱动器设计采用系列服务层次罗列,对象集合.在用户应用程序和具体设备I/O之间建立一种通信机制,用户应用程序通过调用COM接口与设备的输入输出形成功能映射.驱动器的COM接口起"软总线"的作用,使测试程序开发平台和采集卡驱动器实现无缝集成.

| Abstract: | Serial service levels and aggregation of objects were adopted in design of driver for PC data acquisition card based on component object model (COM). A sort of communicating mechanism was set up between user application and I/O of real device. The user application constitutes function mapping by devices output and input through COM interface. COM interface of the driver acts as soft bus, which realizes the integration of test program and acquisition card driver. |
