The invention belongs to the technical field of digital systems, and particularly relates to an extreme value triggering method and device, and the method comprises the steps: starting a first counting process, obtaining a first counting value, judging whether the first counting value is the same as a pre-triggering depth value or not, and if yes, entering a triggering waiting state; starting a second counting process, obtaining a second counting value, judging whether the second counting value is the same as a preset threshold value or not, if not, obtaining a dynamic threshold value from a data point of the waveform data, traversing the data point of the waveform data, judging whether the data point of the waveform data meets a target condition relative to the dynamic threshold value or not, and if yes, executing the second counting process; changing a data point of the waveform data into a dynamic threshold value, and taking a storage position corresponding to the data point of the waveform data as a trigger address; and finishing triggering by taking the current triggering address as a triggering condition until the second count value is the same as the preset threshold value. According to the method, the triggering precision can be greatly improved for signals with variable amplitudes and variable periods, and the possibility of false triggering and missing triggering is reduced.

The utility model discloses an embodiment provides a kind of learning machine, the learning machine includes shell, touch PCBA and plugboard, wherein shell is equipped with accommodating space, accommodating space has upward opening, touch PCBA is accommodated in accommodating space, and covering opening, plugboard is detachably set in opening, and cover is set on touch PCBA, by pressing plugboard, pressure is directly transmitted to touch PCBA, and the path of pressure transmission is less, so trigger accuracy is high.The bottom surface of touch PCBA and the bottom wall of accommodating space are equipped with mutually matched positioning structure, and there is no need to open in touch PCBA with the hole, so there is no trigger blind area.
