The invention provides a waveform peak value detection method and device. The method comprises the following steps: acquiring original data, and segmenting the original data to obtain each segmented data; determining data which is two times greater than standard deviation of the segmented data in the segmented data as to-be-judged data corresponding to the segmented data; performing curve fitting on the to-be-judged data corresponding to the segmented data so as to obtain a curvilinear function corresponding to the segmented data; extracting a maximum value point of the curvilinear function corresponding to the segmented data as a peak value point corresponding to the segmented data; and determining the peak value of the original data according to the peak value point corresponding to each segmented data. According to the manner of segmenting and determining the data which is two times greater than the standard deviation of the segmented data in the segmented data as the to-be-judged data corresponding to the segmented data, the requirements on hardware resources can be reduced, so the detection efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of signal detection, in particular to a waveform peak detection method and device. Background technique [0002] Traditional waveform peak detection methods generally fall into two categories: analog detection and digital detection. The analog detection method is mainly to use the analog circuit method to obtain the peak voltage and then sample to obtain the peak value; the digital detection method is to first sample the signal to be detected to obtain a digital signal, and then analyze the digital signal to obtain the peak value. [0003] The core of the analog detection method is the analog peak hold circuit, which inputs the signal to be detected, and the circuit outputs the detected peak value in the form of an analog signal until the arrival of the clear signal. The basic principle of the peak hold circuit is that the voltage of the input signal and the output signal passes through the comparator, and ...
