A method and device for real-time detection of spectral signal peaks

Abstract

The present application provides a spectrum signal peak real-time detection method, which comprises the following steps: building a spectrum signal peak real-time detection device including an optical filter, an optical filter driver, a detector and a main controller; collecting spectrum signals and converting them into discrete spectrum signal data; judging whether the waveform of the current spectrum signal data is in an upward trend by using a waveform rising detection window; obtaining and updating the local maximum value of the spectrum signal data by using a peak detection update window; judging whether the waveform of the current spectrum signal data meets the waveform peak value detection end condition by using a waveform falling detection window; and taking the obtained local maximum value as the peak value after the voltage driving output cycle is completed. The present application is suitable for peak value detection of various periodic or quasi-periodic spectrum signals, has strong real-time performance and simple steps.
