| 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. |
