The invention provides a method and device for automatically determining a signal time constant, and the method comprises the steps: obtaining a total amplitude value, setting an initial trigger threshold value according to the total amplitude value, and transmitting the initial trigger threshold value to a digital multi-channel lower computer; based on the initial trigger threshold, acquiring pulse sequence data greater than the initial trigger threshold, and setting a new trigger threshold according to the acquired pulse sequence; and based on the new trigger threshold, performing automatic calculation for a time constant, and determining a time constant calculation result. According to the invention, the time constant of the pulse signal can be automatically determined, the time constant parameter can be automatically optimized, and the debugging precision is higher. 本发明提供了一种自动确定信号时间常数的方法和装置，包括：获取总幅度值，根据所述总幅度值，设置初始的触发阈值，并将所述初始的触发阈值下发至数字多道下位机；基于所述初始的触发阈值，获取大于所述初始的触发阈值的脉冲序列数据，并根据获取到的脉冲序列设置新的触发阈值；基于所述新的触发阈值，针
