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(VirtualDeviceDriver)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。
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.
