摘要
在失超探测过程中,电源尖峰干扰信号会引起超导磁铁的保护误动作,影响到磁铁的正常运行。文中叙述了利用移动平均值的方法,对多通道的数据采集信号进行了平滑处理,降低了设定的电压阈值,并减小了失超误动作的发生。该方法可广泛应用于动态数据的采集和处理上。
In quench detection,noise signals originated from the spike effects in the power supply give rise to the quench malfunction action and affect the normal operation of the superconducting magnet. In this paper,the sample data in multiple quench detection channels are smoothed by the moving average method to lower the quench detection threshold,thus reducing the quench malfunction times. The moving average method can be widely used in a dynamic data sampling and data analysis.
