| 摘 要： | 结合电能质量五项指标,开发了用于电能质量检测的数据采集卡。该卡采用了DSP数字信号处理器和PCI总线技术,能实时采集数据。并采用了两片六通道高速A/D转换器和运用了锁相同步技术,对三相电压和电流信号能进行定时采样和等间隔采样,这样得到的数据对于下一步电能质量指标进行分析更为合理。本文最后还简要介绍了DSP的C语言开发和PCI插卡的驱动程序编写技术。

| Abstract: | Considering five parameters of power quality, a digital acquisition board used for power quality detection is developed. Employing DSP technology and PCI bus architecture, the proposed board can collect and process data in real time. This board uses two chips, six channels A/D converter and phase locking synchronous technology for collecting three-phase voltage and current signals in timing and equal-time cycle sampling ways, and the gained data make more reasonable for power quality norm analysis. Finally this paper, briefly introduces utilization of C language to program DSP routine, and the technique of programming PCI device driver. |
