Some Issues About The Mearusing System Of Scanning Sound Intensity

This paper discusses in detail some problems about Scanning Sound Intensify mearusing system of the PC machine from perspectives of both hardware and software . It puts emphasis on analyzing and working out problem of multicenter Data Sampling in phase FIFO amortize arbitrarness waveform generatorThis paper makes a deep discussion on the computer exteral interface technology which is developing in high speed . It analyses Scanning Sound Intensify mearusing system interface technology on the basis of ISA PCI ,and introduce the promising idea about designing mearusing system of Scanning Sound Intensity by using USB interface .The kernel of Windows system are introduced in details. The driver of Scanning Sound Intensify mearusing system is programed by VC++ VtoolsD and DDK. The driver which runs in the kernel of Windows (circle 0 )not only makes the High-Speed and Huge-Capacity data acquisition efficient,but also can work together with the other programs.On the basis of the discussion and analysis above,the mearusing system of Scanning Sound Intensity and its driver are made and designed. The experiments show that the performance and functions of this system reach the requirement very well.
