摘要
介绍的功角测量数据采集卡是采用Cygnal公司C8051F021型单片机实现的PCI总线接口卡。该卡通过2片双口RAM分别实现与GPS接收板和上位机(PC)的数据交换,从而实现高速、可靠的数据采集、处理与传送。本数据采集卡采用片内12位高速ADC并配以片外采样保持电路,通过直接交流采样方法精确快速地实现对电压和电流的采样,保证了电力系统实时测量的要求。
Power-angle measurement data sampling card introduced in this paper is a PCI bus interface card with Cygnal C8051F021 microprocessor.This data sampling card exchanges data rapidly between GPS receiver board and senior computer（PC） with two dual-port RAMs, so it can implement rapid and credible data sampling,handling and transmiting.Morever,this data sampling card adopts 12 bits inchip high speed ADC and out-chip sampling ＆ hold circuit, to implement sampling of voltage and current precisely and expeditiously with AC sampling method,So it guarantees the real time requires in power system.
