LabVIEW环境下的虚拟数据采集与分析系统

Virtual Data Acquisition and Analysis System under LabVI EW Environment

通过采用虚拟仪器技术,使用LabVIEW图形化编程软件和研华的PCI-1711L数据采集卡,并结合石蜡氧化的特点,开发了一种有效的数据采集与分析系统来完成对信号的采集和处理。实验结果表明:该系统完成了对所采集信号的波形显示、数据的自动保存和定时报警等功能。在降低了设备成本的同时,使仪器设备的灵活性和数据处理能力大大提高。

By adopting virtual instrument technique and LabVIEW graphic programming software, as well as the data acquisition card PCI-1711L from Advantech, an effective data acquisition and analysis system has been developed combining with the features of paraffin oxidation. The results of the experiment demonstrate that the functions for waveform display of collected signals, automatic data storage, and alarms have been accomplished by the system. The flexibility and capability of data processing of the equipment are greatly enhanced, while the cost is reduced.
