[0051] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0052] With the continuous development of the field of nuclear energy, in order to ensure the reliability of the construction of the nuclear reactor, it is necessary to construct the required real nuclear reactor by using a three-dimensional model before construction. Due to the need to consider the equipment inspection, transportation and hoisting requirements after the operation of the nuclear reactor in the design process. Therefore, the interference analysis method of the nuclear reaction model appears, which analyzes the interference of the nuclear reaction model by analyzing the deployment position of each nuclear reaction equipment.

[0053] However, in the related art, only the interference analysis of the entity of each nuclear reaction equipment is performed, and the interference of the nuclear reactor model in the spatial dimension is ignored, which reduces the reliability of the interference analysis result.

[0054] Based on this, in one exemplary embodiment, as shown in Figure 1 The interference analysis method of the nuclear reactor model is provided, which is taken as an example of interference analysis equipment in the server, and specifically includes the following steps:

[0055] S101, according to the channel configuration information of the nuclear reactor model and the position information of each channel point, a target channel model corresponding to the nuclear reactor model is constructed.

[0056] Among them, the nuclear reactor model is a three-dimensional model constructed based on the design scheme of the nuclear reactor; the channel configuration information is the basic configuration information of each channel in the nuclear reactor model, such as channel purpose, channel position and channel shape, etc. information; each channel point includes a channel entry point and a channel turning point, the channel entry point is the entry of the channel, that is, both ends of the channel can be the channel entry point, and the channel turning point is the position corresponding to the turning port in the channel; the target channel model is a three-dimensional model constructed by each channel of the nuclear reactor model.

[0057] Before interference analysis, a drawing software can be used to construct a nuclear reactor model that can reflect a real nuclear reactor according to a nuclear reactor design scheme. Among them, the nuclear reactor model includes a plant, system equipment, fire-fighting equipment, electrical equipment and cable bridge, etc., and all model sizes need to completely correspond to the size of the real object.

[0058] In one implementation, the channel configuration information of the nuclear reactor model and the position information of each channel point can be input into the trained channel construction model at the same time, and the channel construction model outputs the target channel model corresponding to the nuclear reactor model according to the channel configuration information, the position information of each channel point and the model parameters.

[0059] In another possible implementation manner, the channel paths between each channel entry point and / or channel turning point can be pre-constructed based on the position information of each channel entry point and channel turning point in the nuclear reactor model; then, based on information such as the purpose of each channel in the channel configuration information, each channel path is adjusted to obtain a target channel model corresponding to the nuclear reactor model.

[0060] For example, the channel paths between channel entry points, the channel paths between channel entry points and channel turning points, and the channel paths between channel turning points and channel turning points are constructed.

[0061] S102: Determine an operable space corresponding to the nuclear power equipment based on obstacle information within the area where the nuclear power equipment is located in the nuclear reactor model.

[0062] Among them, the operable space is used to represent the operating space required by the operation and maintenance personnel when performing maintenance and other processing on the nuclear power equipment. In the embodiment of the present application, a nuclear power equipment can include one or more operable spaces at the same time; the obstacles in the area where the nuclear power equipment is located are used to represent objects that hinder the operation and maintenance personnel from performing maintenance and other processing, and may include but are not limited to other nuclear power equipment and pipelines.

[0063] In one possible implementation method, for any nuclear power equipment, obstacle information within a fixed area where the nuclear power equipment is located can be extracted from the nuclear reactor model, and based on the obstacle information, the obstacle space occupied by the obstacle can be determined; then, the other space within the area except the obstacle space is used as the operable space of the nuclear power equipment.

[0064] In another possible implementation method, for any nuclear power equipment, after determining the obstacle information within the fixed area where the nuclear power equipment is located, the obstacle information and the location information of the nuclear power equipment can be input into a trained space determination model, and the space determination model outputs the operable space corresponding to the nuclear power equipment based on the obstacle information, the location information of the nuclear power equipment and the model parameters.

[0065] S103 , determining a channel interference analysis result of the nuclear reactor model according to the interference between the target channel model and the nuclear reactor model.

[0066] The channel interference analysis results are used to characterize the situation in which the channel is affected, and may include but are not limited to information such as the channel being blocked by nuclear reactor equipment.

[0067] In one embodiment, the constructed target channel model can be compared with the nuclear reactor model to determine whether there is interference between the entity model in the nuclear reactor model and the target channel model, and the channel interference analysis result can be determined based on the determination result.

[0068] For example, if there is any interference between any entity model and the target channel model, it is determined that there is channel interference; if there is no interference between all entity models and the target channel model, it is determined that there is no channel interference.

[0069] After determining the channel interference analysis result, the abnormal position with channel interference can be marked, and the marking result is fed back to the model designer, so that the model designer modifies the nuclear reactor design scheme according to the abnormal position, and ensures that the channel space in the actual nuclear reactor can meet the initial design requirements.

[0070] In S104, a device interference analysis result of the nuclear reactor model is determined according to the target channel model and the operable space.

[0071] The device interference analysis result is used to represent the accessibility of each nuclear power device, that is, if the nuclear power device is accessible, it means that the device does not exist interference; if the nuclear power device is not accessible, it means that the device exists interference. The accessibility is used to represent the case that the operation and maintenance personnel can still reach the operation space of the nuclear power device after carrying tools.

[0072] In an implementation, for any nuclear power device, whether there is at least one channel model that can be connected to the operable space without interference can be determined according to the target channel model and the operable space corresponding to the nuclear power device, and the device interference analysis result of the nuclear power device is determined according to the determination result.

[0073] For example, if there is at least one channel model that can be connected to the operable space of the nuclear power device without interference, it proves that the nuclear power device is accessible, that is, the device interference analysis result of the nuclear power device is that the device does not exist interference; if there is no channel model that can be connected to the operable space of the nuclear power device without interference, it proves that the nuclear power device is not accessible, that is, the device interference analysis result of the nuclear power device is that the device exists interference.

[0074] After determining the device interference analysis result of each nuclear power device, the abnormal nuclear power device with interference can be marked, and the marking result is fed back to the model designer, so that the model designer modifies the nuclear reactor design scheme according to the related information of the abnormal nuclear power device, and ensures that each nuclear power device in the actual nuclear reactor can meet the initial design requirements.

[0075] In the above-mentioned interference analysis method for the nuclear reactor model, a target channel model corresponding to the nuclear reactor model is constructed based on the channel configuration information of the nuclear reactor model and the location information of each channel point. The operable space corresponding to the nuclear power equipment in the nuclear reactor model is determined based on the obstacle information within the area where the nuclear power equipment is located. The channel interference analysis results of the nuclear reactor model are then determined based on the interference between the target channel model and the nuclear reactor model. The equipment interference analysis results of the nuclear reactor model are then determined based on the target channel model and the operable space. Compared to related technologies that only analyze the interference between models corresponding to physical equipment, the above-mentioned method constructs the operable space corresponding to the target channel model and the nuclear power equipment, and analyzes the channel interference and equipment interference conditions separately, which can ensure the comprehensiveness of the interference analysis and thus the reliability of the interference analysis results.

[0076] In order to ensure the accuracy of the target channel model, based on the above embodiment, an optional method of constructing the target channel model is provided in the embodiment of the present application, such as Figure 2 As shown, the specific steps include:

[0077] S201: Construct channel paths between channel points based on the position information of each channel point in the nuclear reactor model.

[0078] Among them, the channel path is used to represent the channel trajectory in the nuclear reactor model.

[0079] In one embodiment, the attribute information (e.g., whether the channel point is a channel entry point or a channel turning point) and location information of each channel point in the nuclear reactor model, as well as the spatial information of the space occupied by each physical facility in the nuclear reactor model, can be input into a trained path construction model. The path construction model outputs a channel path between each channel point based on the attribute information and location information of each channel point, the spatial information of each physical facility, and model parameters. It is understood that there is no interference between the channel path and the physical equipment.

[0080] In another possible implementation, for each channel entry point, the channel entry point can be used as the path starting point, and the next channel entry point / channel turning point can be obtained in the channel forward direction, and the obtained next channel entry point / channel turning point can be used as the path end point to construct a channel path. The channel forward direction can be pre-configured by the designer or automatically planned based on the spatial information of each physical device, and this is not limited in this application.

[0081] In the case that any channel turning point does not reoccur, the channel turning point can be taken as a new path starting point, and the channel path is continuously constructed by referring to the above steps; after the channel paths are constructed, the redundant paths in the channel paths are removed, and the channel paths between the channel points are obtained.

[0082] In S202, first size information of each channel path is determined according to the channel configuration information of the nuclear reactor model.

[0083] The first size information is used to represent the size information of each channel path.

[0084] In an implementation, the first size information of each channel path can be determined according to the channel space shape and channel size of each channel path in the channel configuration information. For example, a normal channel is generally rectangular, and for a special channel, such as a channel for core refueling or a device hoisting channel in a nuclear power design, the first size information of the channel can be defined according to the shape and maximum outer diameter of the transported object.

[0085] In S203, each first size information is used to process the corresponding channel path, and a target channel model corresponding to the nuclear reactor model is obtained.

[0086] In an implementation, for each channel path, a channel contour can be constructed on the basis of the channel path according to the first size information corresponding to the channel path, and a channel model corresponding to the channel path is obtained; then, the channel models corresponding to the channel paths are taken as the target channel model corresponding to the nuclear reactor model.

[0087] It can be understood that the nuclear reactor model corresponding to the real nuclear reactor can have multiple floors, and the channel paths connecting the floors also need to be processed by using the above steps.

[0088] For example, the identification information of the channel entry point A can be taken as an index to query the channel configuration information, and the related configuration information S A of the channel entry point A is obtained; then, the entry contour (first size information) of the channel entry point A is determined according to the related configuration information S A , and the entry contour is taken as a starting point to extend along the channel path L A associated with the channel entry point A, and the channel model A' corresponding to the channel entry point A is obtained.

[0089] In the embodiments of the present application, the target channel model corresponding to the nuclear reactor model is obtained by processing the channel path by using the first size information, which can ensure the rationality of the constructed target channel model.

[0090] In order to ensure the accuracy of the operable space, on the basis of the above embodiment, in the embodiment of the present application, an optional way of determining the operable space is provided, as shown in Figure 3 and specifically includes the following steps:

[0091] S301, determining second size information of the operable space corresponding to the nuclear power equipment according to equipment configuration information of the nuclear power equipment in the nuclear reactor model.

[0092] The equipment configuration information is used to represent the basic configuration information of the nuclear power equipment, including but not limited to equipment size and equipment reserved space information, etc. In the embodiment, the second size information can include the standard operation radius and the standard operation height.

[0093] In an implementable manner, for each nuclear power equipment, the equipment configuration information of the nuclear power equipment can be input into the trained size generation model, and the size generation model outputs the standard operation radius and the standard operation height of the nuclear power equipment according to the equipment configuration information and the model parameters.

[0094] In another implementable manner, for each nuclear power equipment, the minimum operable space size reserved by the nuclear power equipment can be determined according to the equipment configuration information of the nuclear power equipment; then, the standard operation radius and the standard operation height of the operable space corresponding to the nuclear power equipment are determined according to the minimum operable space size and the size information of the region where the nuclear power equipment is located.

[0095] For example, for the nuclear power equipment B, the minimum operable space size of the nuclear power equipment B can be defined as the length L1 extending outward from the equipment shell and the minimum height H1 of the operation space; then, the sum of the size radius of the nuclear power equipment B and the length L1 is taken as the standard operation radius, and the larger value between the maximum size H2 of the nuclear power equipment and the minimum height H1 of the operation space is taken as the standard operation height.

[0096] S302, determining the standard operation region corresponding to the nuclear power equipment according to the position coordinates of the nuclear power equipment and the second size information.

[0097] The standard operation region is used to represent the region where the nuclear power equipment can be operated.

[0098] In an implementable manner, for each nuclear power equipment, the standard operation region of the nuclear power equipment can be constructed according to the position coordinates of the nuclear power equipment and the second size information.

[0099] For example, the standard operation radius and the standard operation height can be used to construct a cylindrical space with the position coordinates of the nuclear power equipment as the center, and the cylindrical space is taken as the standard operation region corresponding to the nuclear power equipment.

[0100] For example, taking the coordinates (x C , y C ) of the device center of the nuclear power device C as the center of the bottom surface of the cylinder, taking the standard operation radius R C as the radius of the cylinder, and taking the standard operation height H C as the height of the cylinder, a standard operation region V C is constructed around the nuclear power device C.

[0101] In S303, the standard operation region is segmented according to the obstacle information in the standard operation region, to obtain the operable space corresponding to the nuclear power device.

[0102] In an implementation, after the standard operation region is determined, the standard operation region can be regarded as a region composed of a plurality of small sectors; then, the small sectors in which obstacles exist are removed, to obtain at least one operable space. The removed regions can be marked as interference regions, for subsequent interference analysis.

[0103] In another implementation, according to the standard operation radius and the standard operation height, an obstacle scanning section with the position coordinates of the nuclear power device as the center of the ground can be constructed; then, the obstacle scanning section is rotated around the nuclear power device, and the space region in which no obstacle exists during the scanning process is taken as the operable space corresponding to the nuclear power device.

[0104] In the embodiments of the present application, by segmenting the standard operation region according to the obstacle information in the standard operation region, the operable space corresponding to the nuclear power device is obtained, which can ensure the accuracy of the determination of the operable space.

[0105] To ensure the rationality of the determination of the operable space, on the basis of the above embodiments, the second dimension information further includes a standard operation width, which is the width of the space close to the side of the nuclear power device in the operable space; further, in the embodiments of the present application, another optional way of determining the operable space is provided, which is as follows:

[0106] According to the obstacle information in the standard operation region, the standard operation region is segmented to obtain each candidate operation space; the candidate operation space in which the candidate space width is greater than the standard operation width is taken as the operable space corresponding to the nuclear power device.

[0107] The candidate operation space is used to represent all the operation spaces obtained after the segmentation; the candidate space width is the width of the space close to the side of the nuclear power device in the candidate space.

[0108] It can be understood that, in the process of the operation and maintenance personnel processing the nuclear power equipment, the operation and maintenance personnel need to face the nuclear power equipment for processing, and therefore, there is a certain requirement for the width of the space near the nuclear power equipment side in each operation space. For example, the width of the space near the nuclear power equipment side needs to be greater than the shoulder width of the operator.

[0109] In an implementable manner, the operation space obtained by segmenting the standard operation area according to the obstacle information in the standard operation area can be taken as a candidate operation space; then, for each candidate operation space, the candidate space width of the candidate operation space can be compared with a preset standard operation width. The standard operation width can be determined based on the experience of the operation and maintenance personnel, or can be determined according to a large number of related tests, and in the present application, no limitation is made thereto.

[0110] If the candidate space width is greater than the standard operation width, it is proved that the candidate operation space meets the operation requirement, and at this time, the candidate operation space can be taken as an operable space; if the candidate space width is less than or equal to the standard operation width, it is proved that the candidate operation space does not meet the operation requirement, and at this time, the candidate operation space can be eliminated.

[0111] In the embodiments of the present application, the standard operation width is introduced, and the candidate operation space with the candidate space width greater than the standard operation width in each candidate operation space is taken as the corresponding operable space of the nuclear power equipment, so as to ensure the rationality of the determination of the operable space.

[0112] In order to ensure the accuracy of the device interference analysis result, on the basis of the above-mentioned embodiments, in the embodiments of the present application, an optional manner for determining the device interference analysis result is provided, as shown in Figure 4 The specific steps include the following steps:

[0113] S401, from each channel path in the target channel model, determining a to-be-verified channel path reaching the operable space.

[0114] The to-be-verified channel path is used to represent a channel path capable of reaching the operable space.

[0115] In an implementable manner, for each nuclear power equipment, the to-be-verified channel path capable of reaching any operable space of the nuclear power equipment can be determined from each channel path in the target channel model according to the position of each channel path.

[0116] S402, judging whether the channel model corresponding to the to-be-verified channel path interferes with the obstacle, if yes, performing S403; if no, performing S404.

[0117] In an implementation, for each nuclear power device, if the channel model corresponding to the to-be-verified channel path interferes with the obstacle, step S403 is performed; if the channel model corresponding to the to-be-verified channel path does not interfere with the obstacle, step S404 is performed.

[0118] For each nuclear power device, if all the channel models corresponding to the to-be-verified channel paths interfere with the obstacle, step S403 is performed; if any of the channel models corresponding to the to-be-verified channel paths does not interfere with the obstacle, step S404 is performed.

[0119] S403, determining a device interference analysis result according to the non-interference region of the nuclear power device and the to-be-verified channel path.

[0120] The non-interference region is a region near the nuclear power device where no interference exists. In the embodiments of the present application, the non-interference region can include, but is not limited to, a free region near the nuclear power device where no interference exists, and other regions that can reach the nuclear power device.

[0121] It can be understood that, for each nuclear power device, if all the channel models corresponding to the to-be-verified channel paths interfere with the obstacle, it is proved that the operation and maintenance personnel cannot directly reach the nuclear power device, at this time, a new channel path can be constructed by adding a channel turning point.

[0122] In an implementation, if the channel model corresponding to the to-be-verified channel path interferes with the obstacle, the non-interference region of the nuclear power device can be used as a path turning point, and a new channel path is generated based on the to-be-verified channel path; then, the operation of S402 is repeated based on the channel model corresponding to the new channel path to determine the device interference analysis result.

[0123] For example, the non-interference region of the nuclear power device can be used to adjust the to-be-verified channel path to obtain an adjusted channel path, and a channel model corresponding to the adjusted channel path is constructed; it is determined whether the channel model corresponding to the adjusted channel path interferes with the obstacle; if yes, it is determined that the device interference analysis result of the nuclear power device is that the device exists interference; if no, it is determined that the device interference analysis result of the nuclear power device is that the device does not exist interference.

[0124] For any nuclear power equipment, the non-interference area of ​​the nuclear power equipment can be used as the path turning point, and the channel path to be verified can be adjusted with the goal of avoiding the interference area to obtain at least one adjusted channel path; then, based on the channel configuration information, the channel model corresponding to the adjusted channel path is reconstructed on the basis of the adjusted channel path, and it is determined whether the channel model corresponding to the adjusted channel path interferes with the obstacle.

[0125] If there is no interference between the channel model corresponding to at least one adjusted channel path and the obstacle, it proves that the operation and maintenance personnel can reach the nuclear power equipment normally based on the adjusted channel path, that is, the nuclear power equipment is a reachable nuclear power equipment. Therefore, it can be determined that the equipment interference analysis result of the nuclear power equipment is that there is no interference with the equipment.

[0126] If interference exists between the channel models corresponding to all adjusted channel paths and the obstacles, it proves that the operation and maintenance personnel still cannot reach the nuclear power equipment, that is, the nuclear power equipment is an unreachable nuclear power equipment. Therefore, it can be determined that the equipment interference analysis result of the nuclear power equipment is that there is equipment interference.

[0127] S404: Determine that the result of the equipment interference analysis of the nuclear power equipment is that there is no interference with the equipment.

[0128] It can be understood that for each nuclear power equipment, when there is at least one channel model corresponding to the channel path to be verified and there is no interference with obstacles, it proves that the operation and maintenance personnel can reach the nuclear power equipment normally, that is, the nuclear power equipment is a reachable nuclear power equipment. Therefore, it can be determined that the equipment interference analysis result of the nuclear power equipment is that there is no interference with the equipment.

[0129] In an embodiment of the present application, the device interference analysis result is determined by judging whether the channel model corresponding to the channel path to be verified interferes with the obstacle, thereby ensuring the accuracy of the device interference analysis result.
