摘要
在数据采集系统中,由于采集硬件或是环境的原因,采集数据中存在零点漂移。在数据的预处理时,需要去除零点漂移。纯硬件的方法使得系统的性价比不高,抑制效果不佳,为此提出了采用软件去除零点漂移的方法。软件的方法简单易行,效果好。用软件的方法结合硬件去除零点漂移,已在HT-7 Tokamak核聚变实验中得到了应用并取得了很好的效果。
Because of the acquisition hardware and the surrounding condition, zero - offset is always existing in the acquired data during the data acquisition. Zero - offset must be eliminated while the acquired data is processed in stepl. A software method to eliminate the zero - offset is presented. It is easy, feasible. Using the software method combined with the hardware method to eliminate the zero - offset have gotten application in the Hefei Tokamak - 7 (HT - 7) experiment and also gotten good results.
