摘　　要：讨论了Windows操作系统下硬件中断产生的方法,使用硬件DIO输出卡对设计的中断服务程序作了多种时序下试验,做了Windows系统下中断服务工作时的干扰试验,在中断线程和工作线程内部提出了多种试验方法,深入研究了Windows系统下的内核级调度执行相关代码段所需的时间,测试了多种时钟的精确度,设计了工程实用的中断服务程序。This paper discusses the generation method of hardware interruption in Windows operation system. The designed interruption service procedure is tested in various time sequences by using hardware DIO output card, and the interference test is carried out when interruption service works in Windows system. Multiple test methods within the interruption threads and work threads are proposed, the required time of imple,nenting the relevant code segment by kernel level scheduling in Windows system is studied intensively, the accuracy of multiple timers is tested, and the interruption service procedure is designed for engineering purpose.
