Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The energy spectrum partitioning method provided by the application can be applied to an application environment shown in figure 1. Wherein the terminal 102 communicates with the server 104 via a network. The user obtains the spectrum to be partitioned through the terminal 102, and sends the spectrum to the server 104, wherein the spectrum to be partitioned is generated by stacking the nuclide counts of the plurality of nuclides. After the server 104 obtains the spectrum to be partitioned, the spectrum to be partitioned can be symmetrically transformed through a preset symmetric transformation function, so as to obtain the initial partition of each nuclide in the spectrum to be partitioned. Further, the server 104 may determine, based on each initial partition, a target peak position corresponding to each nuclide, and then partition the energy spectrum to be partitioned according to each target peak position, to obtain a partitioned target energy spectrum. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices, and the server 104 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a method for partitioning a spectrum is provided, and the method is applied to the server in fig. 1 for illustration, and includes the following steps:
Step S202, obtaining an energy spectrum to be partitioned and an initial partition address, wherein the energy spectrum to be partitioned is generated by superposition of particle counts of target particles corresponding to a plurality of nuclides, and the plurality of nuclides comprise at least two natural nuclides and at least one artificial nuclide.
When the nuclide content in the atmosphere is detected by the detector, the nuclide energy is not concentrated at one point due to the limitation of the detector, but a distribution is presented, and the distribution of a plurality of nuclides is overlapped to form an energy spectrum, which can be specifically generated according to the superposition of particle counts of target particles corresponding to the nuclides, as shown in fig. 3.
In this embodiment, the target particles refer to α particles, β particles, or γ particles. Because the nuclides are different, the energy values of the corresponding target particles are different, and therefore, the distribution positions of the target particles corresponding to different nuclides on the formed actually measured energy spectrum are different after the target particles are detected by the detector.
In this embodiment, the plurality of nuclides may include at least two artificial nuclides and at least one natural nuclide. The artificial nuclide refers to plutonium (Pu), uranium (U), americium (Am) and the like in the artificial nuclear fission process, and specifically can be Pu-239, U-235, U-238, am-241 and the like. The natural nuclides include polonium (Po) and bismuth (Bi) generated after decay of radon-thorium element in soil, such as Po-212, po-214, po-218, bi-212, and the like.
The initial partition address refers to an energy address used for partitioning a target particle corresponding to a natural nuclide in an energy spectrum to be partitioned.
In this embodiment, after the server obtains the energy spectrum to be partitioned, the energy spectrum to be partitioned may be displayed on the display interface, and then the initial partition channel address corresponding to the energy spectrum to be partitioned is determined based on human input.
Step S204, according to the initial partition address, the energy spectrum to be partitioned is initially partitioned to obtain an initial partition energy spectrum, wherein the initial partition energy spectrum comprises initial energy regions corresponding to all natural nuclides.
In this embodiment, the server may perform initial partitioning on the spectrum to be partitioned according to the obtained initial partition address, to obtain an initial partition spectrum after partitioning the target particles corresponding to each natural nuclide.
With continued reference to fig. 3, in the energy spectrum to be partitioned, the initial partition address may refer to partition address T1, partition address T2, partition address T3, and partition address T4, and the initial energy region of the corresponding natural nuclide determined based on the partition address includes a first energy region, a second energy region, and a third energy region.
Step S206, based on each initial energy region, fitting calculation is carried out on target particles corresponding to each natural nuclide, and a corresponding relation between energy addresses in the energy spectrum to be partitioned is established.
The correspondence between energy addresses refers to the correspondence between the energy of the target particles in the energy spectrum to be partitioned and the addresses.
In this embodiment, the server may perform fitting calculation on the target particles corresponding to each natural nuclide according to the initial partition corresponding to each natural nuclide in the initial partition energy spectrum, so as to determine a spectrum peak of each target particle in the energy spectrum to be partitioned, and further establish a corresponding relationship between energy addresses in the energy spectrum to be partitioned according to the spectrum peak and the energy value of the target particle corresponding to each nuclide.
Step S208, according to the corresponding relation, the spectrum peak channel address of the target particle corresponding to each artificial nuclide is determined, and according to each spectrum peak channel address, the initial partition energy spectrum is partitioned, and the partitioned target energy spectrum is obtained.
The spectrum peak address refers to the address corresponding to the spectrum peak of the target particle corresponding to the nuclide on the spectrum to be partitioned, for example, refer to fig. 3, that is, the coordinate position of the X axis corresponding to each spectrum peak.
In this embodiment, after determining the correspondence between energy addresses in the energy spectrum to be partitioned, the server may calculate, based on the correspondence, the spectrum peak addresses of the targets corresponding to the corresponding artificial nuclides in the energy spectrum to be partitioned.
Further, the server may partition the initial partition energy spectrum after performing the initial partition according to the initial partition address according to the calculated peak address of each spectrum, and determine the partition of the target particle corresponding to each artificial nuclide, so as to obtain the target energy region.
In the above-mentioned energy spectrum partitioning method, the energy spectrum to be partitioned is generated by obtaining the particle count superposition of target particles corresponding to a plurality of nuclides, wherein the plurality of nuclides comprise at least two natural nuclides and at least one artificial nuclide, then, according to the initial partitioning channel address, the energy spectrum to be partitioned is initially partitioned to obtain an initial partitioning energy spectrum, the initial partitioning energy spectrum comprises initial energy areas corresponding to each natural nuclide, and based on each initial energy area, fitting calculation is performed on the target particles corresponding to each natural nuclide, a corresponding relation between energy channel addresses in the energy spectrum to be partitioned is established, further, according to the corresponding relation, the spectrum peak channel address of the target particle corresponding to each artificial nuclide is determined, and according to each spectrum peak channel address, the initial partitioning energy spectrum is partitioned to obtain the partitioned target energy spectrum. Therefore, the initial energy region corresponding to each natural nuclide can be determined based on the obtained initial partition address, the corresponding relation between the energy addresses in the energy spectrum to be partitioned is established based on each initial energy region, then the spectrum peak address of the target particle corresponding to each artificial nuclide can be accurately determined according to the corresponding relation between the energy addresses, the energy spectrum of the initial partition is accurately partitioned, compared with the traditional mode of manually partitioning, the artificial error can be reduced, the accuracy and the intelligent level of the energy spectrum partition can be improved, and the calculation precision of the follow-up energy spectrum fitting deduction algorithm can be improved.
In one embodiment, based on each initial energy region, performing fitting calculation on target particles corresponding to each natural nuclide, and establishing a corresponding relationship between energy addresses in the energy spectrum to be partitioned may include: determining two natural nuclides from at least two natural nuclides as target natural nuclides, and determining target initial energy areas corresponding to the target natural nuclides; performing fitting calculation on target particles corresponding to each target natural nuclide based on each target initial energy region, and determining the spectrum peak address of the target particles corresponding to each target natural nuclide; obtaining target energy values of target particles corresponding to each target natural nuclide; and establishing a corresponding relation between energy addresses in the energy spectrum to be partitioned based on the spectrum peak addresses of the target natural nuclides and the corresponding target energy values.
Wherein the target natural nuclide refers to a natural nuclide determined from the at least two natural nuclides, i.e., from Po-212, po-214, po-218, and Bi-212.
In this embodiment, the server may determine any two natural nuclides as target natural nuclides, for example, determine Po-212 and Po-214, then determine the target initial energy regions corresponding to the determined target natural nuclides according to the determined target natural nuclides, and perform fitting calculation on target particles corresponding to each target natural nuclide, so as to determine the spectral peak addresses of the target particles corresponding to each target natural nuclide in the energy spectrum to be partitioned.
In this embodiment, the server may determine, according to the target energy value of the target particle corresponding to each target natural nuclide, the target initial partition corresponding to each target natural nuclide, for example, with continued reference to fig. 3, the target initial partition corresponding to the target natural nuclide Po-212 should be the first energy region, and the target initial partition corresponding to the target natural nuclide Po-214 should be the second energy region.
Further, the server may perform fitting calculation on the target natural nuclide Po-212 and the target natural nuclide Po-214 according to the particle counts of the target particles of each energy channel address in the first energy region and the second energy region, so as to calculate and obtain the spectral peak channel address of the target particle corresponding to each target natural nuclide.
In this embodiment, after obtaining the spectrum peak addresses corresponding to the target natural nuclide Po-212 and the target natural nuclide Po-214, the server may establish a corresponding relationship between energy addresses on the energy spectrum to be partitioned according to the obtained target energy values corresponding to the target particles corresponding to the target natural nuclide Po-212 and the target natural nuclide Po-214.
Specifically, the server can pre-store energy values of target particles corresponding to each nuclide in the database, and then inquire the database based on the type or the identification of the nuclide when the energy values are needed to be used, and acquire the energy values of the target particles corresponding to each nuclide. Or the user can also input the energy value of the target particle corresponding to each nuclide in real time through the input control on the terminal when the energy value of the target particle is required, and send the energy value to the server, so that the server can acquire the energy value of the target particle corresponding to each nuclide.
In this embodiment, the correspondence between energy addresses may be regarded as a linear relationship, and the specific expression is shown in the following formula (1).
E＝kY+b (1)
Where E represents the energy value and Y represents the spectral peak address.
In this embodiment, the server may calculate and determine the values of the parameters k and b in the formula (3) according to the target energy values and the spectrum peak addresses corresponding to the two target natural nuclides, so as to obtain the corresponding relationship between the energy addresses on the energy spectrum to be partitioned.
It will be appreciated by those skilled in the art that the foregoing is merely illustrative, and that in other embodiments, the target natural nuclides may be Po-214 and Po-218, and that the initial energy region of the fitting calculation may be other energy regions, as the application is not limited in this respect.
In one embodiment, based on each target initial energy region, performing fitting calculation on target particles corresponding to each target natural nuclide, and determining a spectral peak address of the target particles corresponding to each target natural nuclide may include: according to the target initial energy region corresponding to each target natural nuclide, fitting calculation is carried out on target particles corresponding to each target natural nuclide, and a distribution function of the target particles corresponding to each target natural nuclide in the energy spectrum to be partitioned is determined; and determining the spectrum peak address of the corresponding target particle corresponding to each target natural nuclide according to each distribution function.
The distribution function refers to a particle distribution function of target particles corresponding to each nuclide in the whole energy spectrum to be partitioned, and the particle distribution function can be specifically a gaussian function or other distribution functions.
In this embodiment, the server performs fitting calculation on the distribution of the target particles corresponding to each nuclide based on the energy spectrum to be partitioned, so as to determine a distribution function corresponding to each nuclide.
In this embodiment, the server may determine the target peak positions corresponding to Po-212 and Po-214, that is, the spectrum peak addresses, by fitting the first partition and the second partition by using a generalized Pareto peak shape function, and the specific fitting formula is shown in (2) below.
Wherein y i represents a particle count of a target particle on an energy track i on the energy spectrum to be partitioned, that is, a particle superposition count of an alpha particle, a beta particle, or a gamma particle corresponding to a nuclide on each energy track i on the initial partition, X i =i represents the energy track i, that is, a scale mark corresponding to an X-axis direction in fig. 3, T 1 represents a right boundary of the first energy region, and T 3 represents a right boundary of the second energy region.
In this embodiment, f k(xi/θk) in the formula (2) represents a fitting function, and its concrete expression is shown in the following formula (3).
Wherein A represents the peak value count of each spectral peak in the energy spectrum to be partitioned, mu represents the peak position of each spectral peak in the energy spectrum to be partitioned, sigma represents the trailing of the distribution of the target particle corresponding to the nuclide on the left side of the peak position of the spectral peak, tau represents the trailing of the distribution of the target particle corresponding to the nuclide on the right side of the peak position of the spectral peak, and k represents the trailing coefficient of the distribution of the target particle corresponding to the nuclide on the right side of the peak position of the spectral peak.
In this embodiment, the server may obtain the accurate peak positions μ 1 and μ 2 of the target natural nuclide Po-212 and the target natural nuclide Po-214 by least squares fitting, so as to obtain the spectral peak addresses corresponding to the two target natural nuclides μ 1 and μ 2, respectively.
In one embodiment, determining a spectrum peak address of a target particle corresponding to each artificial nuclide according to the corresponding relation, and partitioning an initial partitioned energy spectrum according to each spectrum peak address to obtain a partitioned target energy spectrum, which may include: acquiring particle energy values of target particles corresponding to each artificial nuclide; according to the energy value and the corresponding relation of each particle, determining the spectrum peak address of the target particle corresponding to each artificial nuclide in the energy spectrum to be partitioned; based on each spectrum peak address, determining a partition address for partitioning the initial partition energy spectrum, and partitioning the initial partition energy spectrum according to the partition address to obtain a partitioned target energy spectrum.
In this embodiment, the server may input the obtained particle energy value of the target particle corresponding to each of the artificial nuclides into the above formula (1) to obtain the peak address of the spectrum in the energy spectrum to be partitioned corresponding to the target particle corresponding to each of the artificial nuclides.
Further, after determining the spectrum peak address of the target particle corresponding to each artificial nuclide in the spectrum to be partitioned, the server can determine the distribution boundary, namely the partition address, of the target particle corresponding to each artificial nuclide in the initial partition spectrum according to the characteristic of the distribution function of the target particle corresponding to each artificial nuclide, and then partition the initial partition spectrum based on the partition address to obtain the partitioned target spectrum.
In this embodiment, the server may also determine the corresponding artificial nuclides according to the actual application scenario, and then combine the particle energy values of the target particles corresponding to each artificial nuclide and the characteristics of the corresponding particle distribution function to perform energy region division.
In one embodiment, after the energy spectrum to be partitioned is acquired, the method may further include: judging whether the spectrum shape of the energy spectrum to be partitioned is correct or not according to the number of natural nuclides in the energy spectrum to be partitioned and the number of spectrum peaks in the energy spectrum to be partitioned; and when the spectrum shape is determined to be correct, continuing to perform initial partition on the energy spectrum to be partitioned according to the initial partition address to obtain an initial partition energy spectrum.
Referring to fig. 4, after obtaining the spectrum to be partitioned based on the detector, the server may determine whether the spectrum to be partitioned is correct.
In this embodiment, the server may determine whether the spectrum shape of the spectrum to be partitioned is correct according to the number of natural nuclides in the spectrum to be partitioned. For example, the server may determine the number of spectral peaks in the spectrum to be partitioned according to the spectral shape of the spectrum to be partitioned, and determine whether the spectral shape of the spectrum to be partitioned is correct according to the number of spectral peaks and the number of natural nuclides, if only one spectral peak is necessary, the spectrum detected by decay of the natural nuclide should include at least 3 spectral peaks, i.e. corresponding to nuclides Po-212, po-214, po-218 and Bi-212, respectively, where the spectral peaks of Po-218 and Bi-212 overlap to be one spectral peak.
In other embodiments, the server may further determine whether the spectrum to be partitioned is correct according to the spectrum shape of the spectrum to be partitioned, such as distribution.
In the above embodiment, by judging the spectrum shape of the spectrum to be partitioned, and when determining that the spectrum shape is correct, performing initial partitioning on the spectrum to be partitioned according to the initial partition address to obtain the initial partition spectrum, the incorrect spectrum to be partitioned can be filtered, the incorrect spectrum to be partitioned is prevented from being processed, unnecessary data processing amount is reduced, and thus data processing resources can be saved.
In one embodiment, the method may further include: determining an application mode for partitioning the energy spectrum to be partitioned; and determining target artificial nuclides in the energy spectrum to be partitioned according to the application mode.
As previously described, artificial nuclides may refer to Pu-239, U-235, U-238, am-241, and the like. In some scenarios, the artificial nuclide decay may include only one or two of Pu-239, U-235, U-238, and Am-241, e.g., in some scenarios only Pu-239, then its artificial nuclide decay results in target particles corresponding only to Pu-239, or in some scenarios only U, then its artificial nuclide decay results in target particles corresponding only to U, and similarly, when some scenarios only U and Pu are included, then its artificial nuclide decay results in target particles corresponding only to U and Pu.
In this embodiment, the server may set different application modes to detect target particles obtained by decay of target artificial nuclides in the different application modes, for example, referring to fig. 5, the server may include multiple application modes such as application mode Pu, application mode U, application mode Pu and U.
In this embodiment, the server may determine, based on selection of multiple application modes displayed on the terminal interface, an application mode for partitioning the energy spectrum to be partitioned.
In this embodiment, determining, according to the correspondence, a target peak position corresponding to each of the artificial nuclides, and partitioning the initial partitioned energy spectrum according to each of the target peak positions, to obtain a partitioned target energy spectrum may include: and determining a target peak position corresponding to the target artificial nuclide according to the corresponding relation, and partitioning the initial partitioned energy spectrum according to the target peak position to obtain a partitioned target energy spectrum.
Specifically, the server may partition the partition to be partitioned according to the determined application mode and the processing procedure described above, so as to obtain the target energy spectrum corresponding to the application mode.
For example, reference is made to fig. 3,6 and 7, wherein fig. 3 is a target energy spectrum corresponding to various artificial nuclides such as Pu-239, U-235, U-238 and Am-241, fig. 6 is a target energy spectrum corresponding to the application mode Pu, and fig. 7 is a target energy spectrum corresponding to the application mode U.
In this embodiment, as can be seen from fig. 3, 6 and 7, the third energy region and the fourth energy region are divided differently according to different application modes, and the target energy spectrum corresponding to the application mode Pu may further include a fifth energy region.
In this embodiment, the server may send the partitioned target spectrum to the terminal interface for display, and output the partitioned spectrum and the corresponding nuclide to the terminal display interface for display after deduction through subsequent fitting, as shown in fig. 8.
In the above embodiment, the energy spectrum to be partitioned is partitioned according to different application modes to obtain the target energy spectrum corresponding to different application modes, so that the energy region can be partitioned according to the corresponding scene, the accuracy of the energy region partition can be improved, and the accuracy of the fitting and buckling of the energy spectrum can be improved.
In one embodiment, with continued reference to fig. 4, after the server partitions the spectrum to be partitioned to obtain the target spectrum, further determination may be made on the partitioned target spectrum to determine whether the target spectrum meets the requirement, for example, whether there is an obvious error in partition, a partition address is at a peak position of the spectrum, and so on.
In this embodiment, when the server determines that the target energy spectrum does not meet the requirement, the partition of the initial energy region may be performed again based on the energy spectrum to be partitioned, and subsequent processing may be performed. When the server determines that the target energy spectrum meets the requirements, the target energy spectrum obtained after the partitioning can be sent to the upper computer, and the upper computer is used for carrying out subsequent processing and display.
It should be understood that, although the steps in the flowcharts of fig. 2 and 4 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 2 and 4 may include multiple sub-steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor does the order in which the sub-steps or stages are performed necessarily occur in sequence, but may be performed alternately or alternately with at least a portion of the other steps or sub-steps of other steps.
