Description of the embodiments
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It is to be understood that the terms "system," "apparatus," and/or "module" as used herein are intended to be one way of distinguishing between different components, elements, parts, portions, or assemblies of different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.
As used herein and in the claims, the terms "a," "an," "the," and/or "the" are not specific to the singular, but may include the plural, unless the context clearly dictates otherwise. Generally, the terms "comprises" and "comprising" merely indicate that the steps and elements are explicitly identified, and they do not constitute an exclusive list, as other steps or elements may be included in a method or apparatus.
A flowchart is used in the present invention to describe the operations performed by the system according to embodiments of the present application. It should be appreciated that the preceding or following operations are not necessarily performed in order precisely. Rather, the steps may be processed in reverse order or simultaneously. Also, other operations may be added to or removed from these processes.
Examples: for the existing nuclear decommissioning simulation system, the operation or examination of a tester can take the size of the received radiation dose as one of the most important indexes of safety operation, but in a practical task, the operation of performing attribute editing, gesture editing and the like on radiation environment factors such as a radiation source, a shielding body and the like can occur because the simulation system supports an online editing function, so that the requirement of adapting to the higher simulation degree of the actual environment is met.
In view of the above problems, the present embodiment provides a radiation environment editing method for nuclear decommissioning simulation, capable of updating a radiation area in a virtual simulation system in real time, and using a radiation tag group as a capturing mark to ensure accuracy of radiation dose information acquisition, and referring specifically to fig. 1, the radiation environment editing method for nuclear decommissioning simulation provided by the present embodiment includes the following steps:
s100: acquiring a simulation scene distribution diagram at the previous moment, and determining radiation source distribution parameters in the simulation scene distribution diagram, wherein the radiation source distribution parameters refer to the number and the positions of radiation source distribution points of the simulation scene distribution diagram; the step represents timely acquisition of data in a simulation system in the last moment, wherein the data mainly comprises information (such as nuclide name, radiation type, activity concentration, radiation energy spectrum, source item space distribution parameters and the like) of each sub item of a simulation scene distribution map (including an actual modeling environment, radiation source positions and properties, shielding body positions and types and the like), the number and positions of distribution points of a radiation source in the whole simulation environment need to be determined, and the number and positions of all the distribution points form the radiation source distribution parameters. The radiation source herein mainly refers to a three-dimensional virtual model (such as a source-containing facility or a pipeline) of a nuclear decommissioned object, and may be a result of simulation modeling according to field measurement data or a result of simulation modeling according to theoretical calculation.
S200: acquiring a shielding body distribution parameter of each distribution point in the radiation source distribution parameters, wherein the shielding body distribution parameter refers to the number and the positions of shielding body distribution at the distribution point; this step represents the case of taking the shields around each radiation source at its distribution point, including the number and location of each shield distribution, all of which constitute a shield distribution parameter.
S300: calculating the radiation field distribution range of the distribution point based on the radiation source property of the distribution point and the shielding body distribution parameter to obtain a radiation field distribution map; this step represents the calculation of the radiation situation of each distribution point, characterized by the radiation field distribution range, in combination with the radiation properties (radiation attribute parameters) of the radiation source and the shielding capacity (shielding distribution parameters) of its surrounding shielding. The calculation mode can be that the radiation field is calculated by a point-kernel integral or Monte Carlo algorithm, and can also be calculated by a random forest algorithm before.
The random forest algorithm mainly comprises the following steps: s1: acquiring the position and distribution of source item data; s2: generating a plurality of different radiation field data based on a random forest algorithm according to the position and the distribution of the source item data to obtain sample data; s3: dividing the sample data into a training set and a testing set; s4: training a random forest algorithm by using the training set to obtain a plurality of decision trees; s5: generating a plurality of classification results by using the test set and the plurality of decision trees, and taking the average value of the plurality of classification results as a final classification result; s6: and performing visual reduction on the final classification result to obtain an estimation result of the retired radiation field of the post-treatment plant.
Each radiation field distribution range is characterized by a radiation field distribution map, and the radiation field distribution map is, for example, a three-dimensional map, and can represent a distribution area of the radiation field. The plurality of radiation field profiles are visualized throughout the simulated scene profile to facilitate the radiation identification step, step S400: performing visual rendering on all the radiation field distribution diagrams to obtain radiation dose trend lines corresponding to distribution points; this step represents rendering the calculated radiation field data, and displaying the radiation field distribution superimposed with the three-dimensional geometric model (e.g., using a Cartesian or cylindrical coordinate system). The visual display mode of radiation field measurement is a trend line, the trend line can be represented by different colors, the radiation source is used as the center of gravity, the positions with equal radiation doses around are represented by adopting a connecting line mode, and therefore the radiation dose trend line is formed, namely, each radiation source distribution point is provided with a plurality of annular radiation dose trend lines which are overlapped inside and outside.
S500: setting up a radiation target group by combining the distribution of all radiation dose trend lines in the simulation scene distribution diagram; this step means that a plurality of markers characterizing the radiation dose can be obtained throughout the simulated scene distribution map, which markers are mainly represented by radiation dose trend lines along which paths a radiation mark can be established, which can represent at least the radiation dose level there and the previous N display data. It should be noted that, one radiation dose trend line establishes at least one radiation mark, and all the radiation marks form a radiation mark group, so that personnel in each time or each round of test can be allowed to click, inquire and display, so as to verify or control whether the radiation dose data in the test are matched, and provide accurate data support for the final test result.
S600: and acquiring a dynamic editing instruction of the simulation scene distribution diagram at the next moment, analyzing the dynamic editing instruction and updating the radiation target group based on the analysis result. The step represents that after the simulation scene distribution map is edited at the next moment, when the corresponding radiation source distribution parameters and/or shielding body distribution parameters are affected after the analysis of the editing operation, the steps S100-S500 are repeated at the moment, the corresponding radiation mark display information is updated on line, and the updating mode can be supported to be carried out automatically or manually, so that the corresponding radiation dose simulation data can be matched after each radiation scene editing, and more accurate testing results can be obtained.
Compared with the function of online editing of the radiation environment added in the function of the prior simulation system, the technical scheme has the advantages that after the appointed editing instruction is input, corresponding radiation dose parameters can be automatically or manually input to change and displayed in a manner of being inquired, so that the radiation dose data before and after the change can be mastered and checked, the accuracy of the test result of the whole simulation system is greatly improved, and the problem that the reliability of the test result is reduced due to the fact that the simulation operation is carried out along with the previous radiation dose data after the radiation source and/or the shielding body in the modeling environment are edited before is avoided.
On the basis of the above technical solution, in order to reasonably and fully distribute the radiation marks in the simulated scene distribution map, please refer to fig. 2, step S500: the setting up of a set of radiation targets in the simulated scene distribution map in combination with all radiation dose trend lines comprises the following steps S510-S530:
s510: optimizing the radiation dose trend line according to the radiation classification level to obtain a radiation dose trend band corresponding to the radiation dose trend line; this step represents that the radiation dose data is classified by a range of intervals, for example, three-five data lengths are used as a span interval, so that a plurality of radiation dose trend lines can be combined into a radiation dose trend band, wherein the classified interval lengths can be selected according to actual situations, and are not repeated herein. It should be noted that, after the plurality of radiation dose trend lines can be combined into the radiation dose trend band, the radiation dose trend band is also represented in a color-rendering manner.
S520: obtaining all path specification lines of the simulation scene distribution diagram; in the step of obtaining the whole simulation scene distribution diagram, a channel through which simulation operation is required to be carried out is used as the path specification lines, and a tester carries out simulation operation through the path specification lines, so that the specific point position condition of the tester passing through the radiation area can be obtained, and the radiation mark can be conveniently established. Namely, step S530 is performed: a radiometric marker is established based on an intersection of the radiometric dose trend band with the path-planning line, the radiometric marker being a subset of the group of radiometric markers. The method comprises the steps of setting up a radiation mark in an intersection area of a path specification line and a radiation dose trend band, setting up the radiation mark in an intersection plane area if the two-dimensional display is adopted, setting up the radiation mark in an intersection space area if the three-dimensional display is adopted, and forming the radiation mark group by all the radiation marks.
Through the technical scheme, the point positions established by the radiation marks can be reasonably reduced after the radiation dose trend line is optimized into the radiation dose trend band, so that each radiation mark can be positioned on the path planning line to display the radiation dose interval and the level of the point position, and the inquiry operation of test personnel is facilitated.
In order to further optimize the pattern of setting up the radiating marks at the intersection area, for example, the radiating marks may not be set for the smaller intersection area, please refer to fig. 3, in step S530: setting up a radiation target based on an intersection of the radiation dose trend band with the path specification line includes the steps S531-S533 of:
s531: judging the position of an overlapping area of the radiation dose trend band and the path specification line; this step represents capturing and acquiring spatial data of the overlapping region position, and then step S532 is performed: calculating a characterization value of the position of the overlapping area; this step represents a numerical characterization of the size of the overlapping region locations, for example by the number of pixels. S533: if the representation value of the position of the overlapping area exceeds a preset threshold value, setting a radiation mark at the position of the overlapping area; the representation value refers to the occupation size of the position of the overlapping area. The step shows that the radiation mark is set up only for the position of the overlapping area exceeding the specified size, so that the situation that the meaning of setting up the radiation mark at the position of the overlapping area with too small occupied area is not great is avoided.
Furthermore, on the basis of the above solution, in order to further optimize the number of irradiation targets, step S532 further includes the following steps: and acquiring the number of the overlapping region positions, judging the distance parameter of each adjacent overlapping region position on the path planning line, forming a union region from two overlapping region positions corresponding to the distance parameter smaller than a first threshold value, and setting up the radiation mark at the union region. The step indicates that the two overlapping area positions are similar in space (similar refers to similar distances and similar radiation levels) in the case of relatively more overlapping area positions, and the two overlapping area positions can share the same radiation mark, so that the purpose of reasonably reducing the number of the radiation marks is achieved. In the above technical solution, the path-defining line is a single channel forming the path of the simulated scene distribution map, and this is to decompose the path-defining line by using a single element, and the single element is mainly a channel having a single outlet and inlet, such as a straight channel, a curved channel, and the like, so as to reduce the calculation amount of the intersection area.
Referring to fig. 4, in the present embodiment, step S600: the parsing the dynamic editing instruction and updating the radiation label group based on the parsing result includes the following steps S610-S640:
s610: analyzing the type of the dynamic editing instruction; this step represents obtaining targets and objects related to the dynamic editing instruction, extracting all targets and objects, and then performing step S620: calculating modification parameters of the dynamic editing instruction of the type on the radiation source distribution parameters and/or the shielding body distribution parameters; this step represents the acquisition of a specific command structure of radiation source distribution parameters and/or of shield distribution parameters capable of directly influencing the radiation environment parameters, the targets of which are expressed as modification parameters, for example as modification of the shield material parameters or as modification of the radiation source angular distribution parameters.
S630: recalculating the distribution range of all distribution points based on the modification parameters to obtain a modified radiation field distribution diagram and a radiation dose trend line of the corresponding distribution points; this step represents updating the distribution range of all distribution points synchronously by parsing the modification parameters into execution, the distribution range including: and (3) the position, the gesture, the attribute and the like, so that the radiation field distribution diagram of the corresponding distribution point and the radiation dose trend line of the distribution point are recalculated through the steps according to the updated distribution point, and the program of the steps S510-S530 can be executed in the steps of updating the radiation field distribution diagram and the radiation dose trend line of the distribution point to obtain the updated radiation dose trend band distribution condition.
S640: the set of radiation targets is updated in combination with the distribution of the modified radiation dose trend lines in the modified radiation field distribution map. This step represents updating the set of radiating targets at the previous moment by means of the steps shown above, which in this embodiment comprise at least: and performing at least one of position conversion, quantity increase and decrease and parameter modification on the radiating targets of the radiating target group.
According to the technical scheme, the corresponding distribution point parameters are directly updated in a mode of analyzing the dynamic editing instruction, so that the purpose of synchronous update of the radiation mark group is achieved, and the method has the characteristic of being suitable for an automatic update mode. In addition, in some embodiments, in order to facilitate the maintenance personnel to check the parameters in the simulation system and also to control the situation after the overall radiation environment parameters are changed by the test personnel, the step S600 further includes the following steps: the distribution of the previous radiation mark group is integrally compared with the distribution of the updated radiation mark group, the changed radiation marks are marked, and the marking mode is dominant (brightness, color, shape and the like), so that the radiation marks before and after the change can be conveniently and intuitively controlled.
Further, in the present embodiment, the simulated scene distribution map is obtained by a scene editor, comprising the steps of:
and (3) newly constructing a scene: creating a new scene engineering file, and storing model data, scene data and business data; the model data has a format conversion function, and can convert the externally modeled three-dimensional radiation environment into a model format (such as STP format) supported by the system, for example, a PDMS model, an SP3D model, a CATIA model or a PRO/E model is converted.
Scene opening: and opening the scene engineering file, and loading the data into simulation software, for example, by a scene tree mode in a system.
Radiation environment simulation: establishing a radiation dose field simulation model according to the actual acquired data and/or the simulation data;
