Example Embodiment

[0039] Example 1:

[0040] In this embodiment, the sampling frequency is 200MHz and the baseline coordinate is 4050 as the digital pulse data to be processed as an example, and a group of overlapping pulses is separated, such as Figure 2-6 As shown, the specific steps are as follows:

[0041] Step 1: Such as figure 2 As shown, the sampling time is 3243x5x10 -9 s to 3601 x5x10 -9 One pulse in s is an independent pulse with a pulse width of 358x5x10 -9 s; divide the above-mentioned digital pulse data to be processed with a pulse width of 358x5x10 -9 s is the criterion for screening to obtain multiple complete independent pulses and use them as multiple template pulses. image 3 Shown is one of the template pulses.

[0042] Step 2: Extract the pulse height, pulse width, and falling edge data of the multiple template pulses to establish a pulse model library.

[0043] Step 3: Such as Figure 4 As shown, the sampling time in the part of the digital pulse data to be processed is 1x5x10 -9...

Abstract

The invention discloses a digital pulse overlapping peak separation algorithm based on a model base. The digital pulse overlapping peak separation algorithm comprises establishment of a pulse model base and processing of digital pulse overlapping peaks. The algorithm comprises basic steps as follows: firstly, a peak height is taken as a classification index in digital pulse data, pulses which have remarkable pulse peaks and are not overlapped are selected to be template pulses, data such as peak heights, pulse widths and the like are extracted, and the pulse model base is established; secondarily, corresponding pulse templates are matched according to to-be-separated overlapping pulse peak heights, and overlapping peaks are separated.

Description

technical field [0001] The invention belongs to the research field of nuclear energy spectrum measurement, in particular to a digital pulse overlapping peak separation algorithm based on a model library. Background technique [0002] In recent years, online measurement technology has developed rapidly, and the measurement of nuclear energy spectrum is a commonly used online measurement technology. The nuclear energy spectrum is measured by a spectrometer with a high count rate, and the digital pulse after high-speed acquisition needs to be processed in the process. In these digital pulses, the phenomenon of overlapping peaks is very obvious, so these overlapping peaks need to be processed to improve the resolution of the measuring instrument. The existing overlapping peak separation algorithms mainly use overlapping peak fitting, iteration, least squares and other methods to separate overlapping peaks. The algorithm is relatively complicated and the amount of calculation is...
