| Abstract: | A virtual instrument is made up of data acquisition, data analysis and processing and data display modules. There are many famous platform for software development, such as LabView, VC++ etc. The hardware of virtual oscillograph includes a microcomputer with ISA interface, an AC1820data-acquisition card. The data-analysis and processing module and data-display module was integrated with software developed by VC++ platform. The key technology of hardware is application of the high-speed, multi-port data-acquisition device supported by high-speed bus, the real-time effect of waveform display was enforced. The key of software is the plementation of data-acquisition and data processing program. Meanwhile, the multi-tread technique was applied to ensure the display effect. |
