摘　　要：时统接口卡是基于PCI总线的即插即用扩展卡，其主要功能是接收输入的时统信号以获取统一的系统时间并保持高精度的准秒同步，同时给外系统提供准秒1PPS、B（DC）码以及定制的脉冲等信号。本文介绍了基于WDM模型的时统接口卡驱动程序设计，主要介绍了驱动框架的实现，中断的处理以及驱动程序接口函数库的设计和实现。Time unification system interface card is a type of PnP extended card based on PCI bus. Its main function is to receive the time information signal from an external system, to get unified system time and to maintain synchronization with the external system. At the same time, it provides the external system with accurate second signal 1PPS, IRIG B （DC） code and custom-built pulse signals. This paper introduces design of the driver for time unification system interface card based on WDM. Specifically, it mainly introduces implementation of the driver frame, processing of interruptions and design and implementation of driver DLL.
