Validity feature peak in S11, acquisition Raman spectroscopy；Obtain the spectroscopic data of each point in Raman spectroscopy Intensity value.

In the present embodiment, Raman spectrum (Raman spectra) is a kind of scattering spectrum.Raman spectrum analysis method is Based on the Raman scattering effect that India's scientist's C.V. Raman is found, the scattering spectrum different from incident light frequency is divided Analysis is applied to a kind of analysis method of molecular structure research to obtain molecular vibration, rotation aspect information.In this step, The characteristic peak obtained in Raman spectroscopy can pass through characteristic peak and preset Raman in Raman spectroscopy Characteristic peak in spectrum spectrogram is compared, and determines the corresponding substance of the Raman spectroscopy with this, if Raman Spectra The case where characteristic peak in figure, is unsatisfactory for corresponding condition, then can not go to compare according to the characteristic peak in the Raman spectroscopy To the corresponding substance of the Raman spectroscopy, in this step, each validity feature peak in Raman spectroscopy is obtained, is passed through Whether validity feature peak determines Raman spectroscopy effective, while obtaining the strong of the spectroscopic data of each point in Raman spectroscopy Degree comprising the intensity value of each trough in the intensity value at above-mentioned validity feature peak, Raman spectroscopy works as Raman spectroscopy When the middle substance occurred in addition to substance to be detected, detected Raman spectroscopy just will appear abnormal Raman spectrum number According to since Raman spectrum data is generated due to laser, in the detection process, the interference of light also can be to the Raman detected Spectrum spectrogram has an immense impact on.

As shown in figure 3, specifically, in the present embodiment, the validity feature peak obtained in Raman spectroscopy may include Following steps:

S21, denoising smooth operation is carried out to Raman spectrum data, obtains the Raman spectrum data of denoising smooth.

In the present embodiment, since the Raman spectrum data got will appear multiple characteristic peaks, meanwhile, it can be due to noise Cause waveform unsmooth, erroneous judgement be easy to cause to think that noise is characteristic peak, in this step, to obtained Raman spectrum data into The operation of row denoising smooth, can be by denoising methods such as median filtering, mean filter and total variation denoising methods to Raman spectrum Data carry out denoising smooth operation.

S22, acquisition remove dryness the wave crest in smooth Raman spectrum data, as validity feature peak.

In the present embodiment, the wave in Raman spectrum data can be relatively determined by the intensity value in Raman spectrum data Peak, for example, any intensity value is stronger than the intensity value of the intensity value of the former point and the latter point, then confirmation should Point is wave crest, alternatively, to the Raman spectrum data derivation, the point when derivative for obtaining the Raman spectrum data is zero, the point is then The wave crest in Raman spectrum data can be obtained in conjunction with the derivative value of the point before and after the point for wave crest or trough.

S12, whether the number of characteristic peak is confirmed the validity less than the first preset threshold.

In the present embodiment, confirm whether the number at the validity feature peak obtained in above-mentioned steps reaches the first default threshold Value, in the detection process, since Raman spectrum is to generate due to scattering, and the molecular structure of substance to be detected and rotation all can shadows Ring to scattering the case where, so, will appear the wave crest of a large amount of varying strengths in the Raman spectroscopy finally generated, effectively spy When sign peak number amount is very few, which greatly may be by external interference, for example, visible light is dry in acquisition process It disturbs, the intensity that will lead to Raman spectrum in the period for visible light occur is zero, and the laser that Raman spectrometer 1150 is emitted is not It is directed at substance to be detected, so, whether the quantity for confirming the validity characteristic peak in this step is greater than or equal to preset threshold, with true Whether effective determine Raman spectroscopy.

S13, it is confirmed whether that the intensity value of the spectroscopic data there are any point is lower than the second preset threshold.

In the present embodiment, confirm in Raman spectroscopy whether have the intensity value of the spectroscopic data of any point too low, the Two preset thresholds can be set to 0, may be set to be other numerical value, for example, occurring visible light interference in detection process, it is seen that The interference of light will lead to spectroscopic data lower than zero, meanwhile, it, can be to testing result if occurring the interference of visible light in the detection process Tremendous influence is generated, alternatively, in the detection process, laser misalignment substance to be detected leads to generated spectroscopic data Intensity is too low, and the intensity value of the spectroscopic data by confirming each point confirms in the acquisition process of Raman spectroscopy whether occur Abnormal interference, and then determine whether Raman spectroscopy is effective.

If the number at S14, validity feature peak is less than the first preset threshold, or/and there are the strong of the spectroscopic data of any point Angle value is lower than the second preset threshold, it is determined that Raman spectroscopy is invalid.

In the present embodiment, validity feature peak number is less than the first preset threshold and there are the spectroscopic datas of any point Intensity value lower than the second preset threshold arbitrarily occur one when, it can confirm in the collection process of Raman spectroscopy and generate The situation of external disturbance or acquisition inaccuracy, so, which can be considered as to invalid spectrogram.
