【摘要】 在Ht-7实验中,数据采集是获取实验数据的主要途径,利用.NET技术对原采集控制系统的改进,实现可变时间的数据采集,并且能够根据等离子体电流特征而实时终止采集。因此,不仅可以提高Ht-7实验的工作效率,而且能够针对特殊诊断信号改善它们数据的品质。实验证明,在长脉冲放电过程中,改进后的系统具有明显的效果。更多还原

【Abstract】 In Ht- 7, the data acquisition is a main approach of the collection experimental data. It realizes the data acquisition that the length of acquisition time is alterable by improving the original data acquisition system, and terminates immediately the task of the data acquisition when the plasma current vanishes. Therefore, not only it may enhance the efficiency of the experimental action, but also may improve the data character of the special signal. It is proved in the experiments that the new control system of the data acquisition shows an enhanced capability in the long pulse discharge.更多还原
