Specific embodiment
Here exemplary embodiment will be illustrated in detail, example is illustrated in the accompanying drawings.Following description is related to
During attached drawing, unless otherwise indicated, the same numbers in different attached drawings represent the same or similar element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the disclosure.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the disclosure.
Before the determination methods, device, storage medium and the electronic equipment that deviate in the focus for introducing disclosure offer, first
Application scenarios involved by each embodiment of the disclosure are introduced.The application scenarios are to determinand using Raman detection equipment
Body carries out substance detection, and laser emitter and spectrometry sensor device are provided in the Raman detection equipment.Laser transmitter projects
Laser irradiates object under test, and object under test scatters Raman spectrum under the irradiation of laser, which draws for collecting
Graceful spectroscopic data.What deserves to be explained is the Raman spectrum data that spectrometry sensor device is collected is real-time accumulated storage, that is,
It says, in the case where not removing sensing data, the Raman spectrum data which is collected into is to start to be collected into
Total data that current time adds up.
Fig. 1 is the flow chart for the determination methods that a kind of focus provided according to the embodiment of the present disclosure deviates, as shown in Figure 1,
This method includes：
S11, emit laser and during carrying out Raman spectral collection in Raman detection equipment, duration is fixed at interval of one
The spectrometry sensor device of the record once Raman detection equipment adds up the Raman spectrum data being collected into or whenever being collected into
The brightness value of Raman spectrum often increase the spectrometry sensor device of the fixed value record once Raman detection equipment and add up to receive
The Raman spectrum data collected.
What deserves to be explained is Raman detection equipment specifically in detection process, be typically open the first half time laser with
It irradiates article to be measured and collects Raman spectrum, the later half time closes laser, but still keeps former gripping gesture, and starts sensing
The interference information of device collecting circuit and ambient light etc..In this case, above-mentioned steps S11 is described to Raman spectrum data
It is in the period for collecting Raman spectrum in Raman detection equipment continuous emission excimer laser to carry out record.
Specifically, step S11 includes following two modes：
The spectrometer of the Raman detection equipment is recorded once described in mode one, step S11 at interval of a fixation duration
Sensor, which adds up the Raman spectrum data being collected into, to be included：According to the Laser emission total duration M of the Raman detection equipment
Detection duration is divided into N number of isochronous surface；The spectrometry sensor of the Raman detection equipment is recorded once at interval of duration M/N
Device adds up the Raman spectrum data being collected into.
Illustratively, in a kind of possible realization method, it is (i.e. above-mentioned that Raman detection equipment can set a fixed duration
Laser emission total duration M) Laser emission is carried out, such as 2s, reaching the time then thinks that Raman spectral collection terminates.N can be comprehensive
Consider the preset value of computing capability of total duration M and Raman spectroscopy equipment.Wherein, the more big each isochronous surfaces of M are bigger,
It may influence to judge precision, N is more big, and each isochronous surface is smaller, requires computing capability higher.
Described in mode two, step S11 one is recorded whenever the brightness value for the Raman spectrum being collected into increases a fixed value
The spectrometry sensor device of the secondary Raman detection equipment, which adds up the Raman spectrum data being collected into, to be included：According to the Raman
The brightness of Raman spectrum data is divided into N number of brightness and cut into slices by the detection total luminance value B of detection device, the detection total luminance value
Refer to that the Raman detection equipment stops detection when the brightness value for the Raman spectrum data being collected into reaches B；The drawing being collected into
The spectrometry sensor device that the brightness value of graceful spectrum often increases the B/N records once Raman detection equipment adds up the Raman being collected into
Spectroscopic data.
Illustratively, in a kind of possible realization method, Raman detection equipment can also set the peak at a peak, such as
The longitudinal axis reaches 40000 (sensor brightness values), then it is assumed that current integration duration is up to standard, terminates Raman spectral collection.Herein
In the case of kind, above-mentioned detection total luminance value B is the sensor brightness value of Raman detection equipment setting.In addition, N can be comprehensive
Consider the preset value of computing capability of total luminance value B and Raman spectroscopy equipment.
In the specific implementation, above two mode can select an execution to the embodiment of the present disclosure.
The wave crest information for the Raman spectrum data that S12, extraction record each time.
Illustratively, the following table 1 is shown in the case of using aforesaid way one, the wave crest letter of the Raman spectrum data of extraction
Breath.
Table 1
Wherein, with reference to table 1, when Raman detection equipment Laser emission duration reaches M, stop collecting Raman spectral information, altogether
Record data n times.What deserves to be explained is the data recorded every time are spectrometry sensor devices start collect Raman spectrum to it is current when
Carve the accumulative total Raman spectrum data being collected into.
Another example, the following table 2 shown using in the case of aforesaid way two, the ripple of the Raman spectrum data of extraction
Peak information.
Table 2
With reference to table 2, when the brightness value for the Raman spectrum that Raman detection equipment is collected into reaches B, stop collecting Raman spectrum
Information records data n times altogether.
In addition, the wave crest extracted with reference to Tables 1 and 2, the embodiment of the present disclosure according to the Raman spectrum data recorded each time
Information can include the peak value of wave crest and the position of appearance.Specifically, wave crest letter is illustrated with Fig. 2 a and Fig. 2 b below
Breath.
Fig. 2 a are the schematic diagrames of the Raman spectrum data 2 in table 1, and as shown in Figure 2 a, Raman spectrum data 2 includes two ripples
Peak, peak value are respectively y12 and y22, and the position that peak value occurs is x1 the and x2 location points of X-axis respectively, therefore, is recorded in table 1
Wave crest information be (x1, y12) and (x2, y22).Fig. 2 b are the schematic diagrames of the Raman spectrum data 3 in table 1, as shown in Figure 2 b,
Raman spectrum data 3 includes two wave crests, and peak value is respectively y12, y22 and y33, and the position that peak value occurs is X-axis respectively
X1, x2 and x3 location point, therefore, the wave crest information recorded in table 1 be (x1, y13), (x2, y23) and (x3, y33).
The Raman spectrum data that S13, the wave crest information of the Raman spectrum data recorded according to n-th are recorded with (n+1)th time
Wave crest information, determine n-th record Raman spectrum data each wave crest to (n+1)th time record when rate of rise.
Wherein, n is the positive integer more than 0 and less than N, and N is the total degree of record Raman spectrum data.
It is still illustrated by taking Fig. 2 a and Fig. 2 b as an example, according to table 1, the Raman spectrum data 2 of the 2nd record includes two
A wave crest (x1, y12) and (x2, y22), when two wave crests are to the 3rd record, the wave crest in corresponding Raman spectrum data 3
(x1, y13) and (x2, y23), it follows that wave crest (x1, y12) to the 3rd time record when, rate of rise for (y13-y12)/
Y12, when wave crest (x2, y22) is to the 3rd record, rate of rise is (y23-y22)/y22.
In addition, in a kind of possible realization method, the Raman spectrum data recorded each time extracted in step S12
The peak value that wave crest information includes in the Raman spectrum data that records each time is more than the peak value of the wave crest of predetermined threshold value and described
The position that wave crest occurs.In this way, step S13 is specifically included：According to the peak value of primary peak and (n-1)th Raman light recorded
The peak value of the position wave crest identical with the position of the primary peak determines the rate of rise of the primary peak, institute in modal data
State any wave crest that the peak value in the Raman spectrum data that primary peak is n-th record is more than predetermined threshold value.
That is, the information that the wave crest information recorded in table 1 or table 2, which is peak value, is more than the wave crest of predetermined threshold value.Such as
Y0 shown in Fig. 2 a and Fig. 2 b, the wave crest recorded in table 1 for wave crest of the peak value more than y0 information.
S14, judge n-th record Raman spectrum data each wave crest rate of rise it is whether consistent.
Illustratively, when the wave crest (x1, y12) in table 1 in the Raman spectrum data 2 of the 2nd record is to the 3rd record, increase
Long rate is (y13-y12)/y12, and when wave crest (x2, y22) is to the 3rd record, rate of rise is (y23-y22)/y22.
Therefore, if (y13-y12)/y13=(y23-y22)/y23, each wave crest of the 2nd record Raman spectrum data
Rate of rise is consistent or (y13-y12)/y13- (y23-y22)/y23=0, then the 2nd record Raman spectrum data is each
The rate of rise of a wave crest is consistent.
What deserves to be explained is but because being influenced by actual environment factor, certain error range should be left, therefore, this
Open embodiment is in the specific implementation, it can be determined that the difference of the rate of rise of each wave crest or the ratio between whether in default error
Within the scope of, the rate of rise of each wave crest difference or the ratio between be in the default error range when, determine each wave crest
Rate of rise it is consistent, the rate of rise of each wave crest difference or the ratio between be not in the default error range when, determine
The rate of rise of each wave crest is inconsistent.
S15, n-th record Raman spectrum data each wave crest rate of rise it is inconsistent when, determine the drawing
Focus, which occurs, for the laser of graceful detection device transmitting deviates.
Due to for a kind of Raman spectrum of object under test, the growth ratio for each wave crest that different position occurs is
Equal, therefore, if the rate of rise of each wave crest of the Raman spectrum data of n-th record is inconsistent, show to be collected into
The Raman spectrum data of other substances may thereby determine that the laser of Raman detection equipment transmitting occurs focus and deviates.
Therefore, using above method step, the multiple recording light spectrometer sensor of the embodiment of the present disclosure adds up the drawing being collected into
Graceful spectrum, and whether the growth ratio of each wave crest is unanimously judged, laser spot finally can determine according to judging result
Whether there is offset, without user by micro-judgment, avoid since focal shift causes in the Raman spectrum of collection
Happening for the Raman spectrum of other objects is mixed into, and then the accuracy of substance detection can be improved.
In addition, what deserves to be explained is, it is consistent in the rate of rise of each wave crest of the Raman spectrum data of n-th record
When, due to that may occur new wave crest in new position in the Raman spectrum data of (n+1)th record, for example, referring to Fig. 2 a
With Fig. 2 b, the Raman spectrum data of the 2nd record occurs new wave crest in x3 positions, due to the Raman spectrum number of n-th record
According to same position do not record the wave crest, therefore can not judge emerging wave crest rate of rise whether with other wave crests increase
Long rate is consistent, so as to when the rate of rise of each wave crest of the Raman spectrum data of n-th record is consistent, determine institute
Focus deviation does not occur for the laser for stating the transmitting of Raman detection equipment.
Therefore in the embodiment of the present disclosure, if the rate of rise of each wave crest of the Raman spectrum data of n-th record is consistent,
And each wave crest of the Raman spectrum data compared to n-th record, the Raman spectrum data of (n+1)th record is not in new position
There is the wave crest that peak value is more than predetermined threshold value, then can determine that the laser of the Raman detection equipment transmitting is recorded n-th in n-th
Focus deviation does not occur between+1 record.But the rate of rise of each wave crest in the Raman spectrum data of ith record
Unanimously, each wave crest of the Raman spectrum data and compared to ith record, the Raman spectrum data of i+1 time record is new
When the new wave crest that peak value is more than predetermined threshold value occurs in position, at least need to combine the i+2 Raman spectrum data recorded into one
Step judges the rate of rise of emerging wave crest, is deviateed with determining whether to occur focus, wherein, i is greater than 0 and is being less than N-1 just
Integer.
It is recorded for last time, if the rate of rise one of each wave crest in the Raman spectrum data of the N-1 times record
It causes, and each wave crest of the Raman spectrum data compared to the N-1 times record, the Raman spectrum data of n-th record is in new position
It puts and the new wave crest that peak value is more than predetermined threshold value occurs, then additional method is needed to judge focus whether without departing from for example, this public affairs
Open data of the Raman spectrum data on the new position that the method for embodiment offer can record according to the N-1 time and
The peak value of the emerging wave crest, judge the new wave crest rate of rise whether with the N-1 times record Raman spectrum data
Each wave crest rate of rise it is consistent, if the Raman spectrum data that the rate of rise of the new wave crest is recorded with the N-1 time
The rate of rise of each wave crest is consistent, it is determined that n-th note is recorded at the N-1 times for the laser of the Raman detection equipment transmitting
Focus deviation does not occur between record；If the rate of rise of the new wave crest is each with the Raman spectrum data of the N-1 times record
The rate of rise of wave crest is inconsistent, it is determined that n-th record is recorded at the N-1 times for the laser of the Raman detection equipment transmitting
Between occur focus deviate.
Although that is, the N-1 times record Raman spectrum data may not occur in the new position wave crest or
There is wave crest in person, but since peak value is not extracted by not less than predetermined threshold value (y0 as shown in Fig. 2 a or Fig. 2 b), not
It is recorded in table 1, still, can still utilize the Raman spectrum data of the N-1 times record in the actual number of the new position
Value judges the rate of rise of emerging wave crest.
It follows that in the specific implementation, the setting of predetermined threshold value y0 is smaller, the wave crest number extracted is more, follow-up to remember
The probability that the Raman spectrum data of record compares the new wave crest of the Raman spectrum data appearance recorded before is smaller, and predetermined threshold value y0 takes
It is worth excessive, it is also possible to which laser caused by there is shake was radiated in the time on another article, not the peak of another article
Value can reach happening for y0.Specifically, the total degree N of threshold value y0 and record can pass through according to scene and user
Experiment calibration in advance.
Further, the determination methods that the focus that the embodiment of the present disclosure provides deviates, can when definite laser spot deviates
To export prompting message, to remind user that laser spot has deviateed, whether Raman detection is re-started by user's decision-making,
It can be when exporting prompting message, while remove the data of spectrometry sensor device, mandatory requirement user re-starts Raman
Detection.The disclosure does not limit this.
In addition, what deserves to be explained is, for above method embodiment, in order to be briefly described, therefore it is all expressed as to a system
The combination of actions of row, but those skilled in the art should know, the disclosure and from the limitation of described sequence of movement.Example
Such as, step S12 to step S15 can be held between record Raman spectrum data every time and next time record Raman spectrum data
Row is checked and reminded so as to fulfill real-time, once it is determined that focus deviates, then can remind user at once, and using reply
Measure, such as stops Laser emission, and preparation re-starts detection.But in the case where the intra-record slack byte time twice is too small, Raman
The computing capability of detection device, which may be not enough to be supported on the interval recorded twice, pre-processes and carries peak algorithm, therefore, step
S12 to step S15 can also collect to complete to perform afterwards in Raman spectrum data, for example, transmitting laser duration reaches default
Total duration or wave crest perform after reaching the peak value that triggering stops, in this case, however, it is determined that go out during Raman detection
Show focal shift, it still can be with output quality detection as a result, user's decision-making is allowed whether to need to re-start detection.
