| 摘要: |
| 根据电力系统实时数据采集的需要，为克服多任务操作系统实时性差的问题，研究Windows操作系统下数据采集的硬件中断方法，深入了解用VtoolsD开发非标准设备（如数据采集卡）驱动程序VxD(Virtual Device Driver)的原理，流程及编程方法等，运用VxD技术开发了12位增强型多功能数据采集卡PCL－818L的驱动程序，从而能在Windows操作系统下，对电网电压，电流数据进行实时采集与分析，并具备友好的人机界面。 |

| Abstract: |
| In order to meet the demand of real-time data collecting in power system the real-time performance in multitasking operating system should be improved.The hardware interruption technique for data collecting in Windows operating system is studied,and the principle,procedure and pro-gramming method for developing a VxD(Virtual Device Driver)of non-standard device with VtoolsD is explored.With VxD technique,the driver of a12-bit enhanced multi-function data-acquisition card PCL-818L is developed.It can real-timely collect and analyze the voltage and current data of power system in Windows operating system,and has a friendly MMI. |
