摘要： 在Windows系统中，PCI/CPCI总线模块的故障诊断实时性较差。为此，提出一种基于底层驱动的故障诊断软件构建方法。将虚拟诊断驱动作为软件底层，使用DriverWorks的核心层类实现设备枚举、设备资源初始化等功能，通过状态寄存器实时监控设备的工作状态，结合中间件和应用软件完成对设备的故障诊断。实验结果表明，该软件运行稳定，实时性较好，且诊断功能可随意扩充。

Abstract: According to PCI/CPCI bus computer’s real-time fault diagnosis problem, this paper proposes a way of building fault diagnosis based on the underlying software. The method relies on the virtual device driver as the underlying support, through the DriverWorks core layer class enuming device and initializing the device resource. It monitors the device working status by using status register. Combined with the middleware and application software, it completes the equipment fault diagnosis function. Experimental results show that the software is stable, has strong real-time, and diagnostic functions can be extended.

Key words: fault diagnosis, low-level driver, virtual device driver, network equipment diagnosis
