Abstract

The invention discloses a baseline processing method and device of a pulse signal and a particle detection system. The baseline processing method of the pulse signal comprises the following steps of:sequentially acquiring data of each sampling point in a to-be-processed pulse signal; acquiring an average value of the data of a current sampling point and a continuous preset number of sampling points before the current sampling point, and taking the average value as a baseline value corresponding to the current sampling point; and subtracting the corresponding baseline value from the data of each sampling point to obtain baseline-removed data of each sampling point, thereby obtaining a baseline-removed target pulse signal. Through the mode, the influence of baseline fluctuation on the accuracy of pulse recognition can be reduced, so that the accuracy of pulse signal recognition is improved.

Description

technical field [0001] The present application relates to the technical field of signal processing, in particular to a baseline processing method and device for pulse signals, and a particle detection system. Background technique [0002] When processing a pulse signal, it is generally necessary to obtain characteristic data such as amplitude, pulse width, and shape of the pulse signal, from which other characteristics corresponding to the pulse signal can be further obtained. For example, when studying the pulse signal generated by particles, these characteristic data can represent the characteristics of different particles, such as the peak characteristic is proportional to the volume of the particle, and a peak reflects a particle. [0003] The existing pulse identification is to save the data collected for a period of time, and then upload it to related equipment, and then perform pulse identification. There are two shortcomings in this method: shortcoming one, data pre...
