摘要
虚拟仪器主要由数据采集、数据分析处理、数据输出与显示三部分模块组成。其软件开发平台有LabView、VC++ 等。该虚拟示波器硬件包括一台带ISA接口微机、一块ISA数据采集卡AC1820;软件集波形点数据分析、输出、显示为一体,用VC++ 设计。硬件关键是采用高速总线支持的高速多通道数据采集卡,以增强波形显示的实时性。软件关键是数据采集、处理程序实现。为保证显示效果,采用多线程技术。
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.
