[0023] The technical solutions of the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0024] The nuclear power plant risk control method provided by the embodiment can be applied in an application environment as shown in Figure 1 , in which a client communicates with a server. The client includes but is not limited to various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices. The server can be implemented by an independent server or a server cluster composed of multiple servers.

[0025] In an embodiment, as shown in Figure 2 , a nuclear power plant risk control method is provided. The server in the application environment as shown in Figure 1 is taken as an example for illustration, and the method includes the following steps S10-S40.

[0026] S10, obtaining nuclear power plant work order data; the nuclear power plant work order data includes seal data and process data;

[0027] It can be understood that the nuclear power plant work order data refers to data related to the nuclear power plant work order generated based on the nuclear power plant work order. The nuclear power plant work order is generated by a client according to the demand of a nuclear power plant worker, and the nuclear power plant work order includes relevant information such as seal, planned factory, work center, work order type, work order priority and function position. The seal data includes the images of a plurality of electronic seals and the corresponding name information of each electronic seal. The process data refers to the data of a plurality of processes generated according to the nuclear power plant work order.

[0028] S20, performing image recognition on each electronic seal in the seal data to obtain an image recognition result; and matching corresponding seal risk information for each electronic seal based on the image recognition result, so as to enable a user to perform a confirmation operation on a plurality of seal risk information on the client.

[0029] It can be understood that different operation types correspond to different approval procedures, such as different approval processes and approval persons, in the operation process of a nuclear power plant. A nuclear power plant work order may involve multiple operation types, and the nuclear power plant work order will involve multiple approved electronic seals. Different electronic seals correspond to different nuclear power plant operation permissions. Image recognition refers to a process of identifying the seal image of each electronic seal in the seal data by a seal identification model to obtain an image recognition result. The image recognition result includes the identification result of each electronic seal, i.e., the classification result of each electronic seal. For example, the seal data contains three electronic seals (A1, A2, A3), and the image recognition result can be (A1: modification project, A2: sensitive area, A3: important area). The seal risk information includes risk prompt information and / or safety measure information. Different electronic seals correspond to different seal risk information. The nuclear power plant staff can click on the nuclear power plant work order page on the client to view the seal risk information corresponding to each electronic seal and confirm it. Only when the user confirms the seal risk of each electronic seal can the ticket taking operation be performed. The user can be a login account of the nuclear power plant staff. Preferably, different seal risk information corresponds to different users, i.e., different seal information needs to be confirmed by different nuclear power plant staff.

[0030] Preferably, after obtaining the image recognition result, the authenticity of the seal image can be further identified. When a false electronic seal is identified in the seal data, a warning information is generated to make the nuclear power plant staff receive the warning information to further confirm the electronic seal identified as a false seal, so as to avoid misoperation caused by human error.

[0031] S30, based on a preset procedure sorting rule, sorting each procedure in the procedure data to obtain a procedure sorting result; and matching each procedure with corresponding procedure risk information for user confirmation operation on the client according to the procedure sorting result.

[0032] It can be understood that during the operation process of the nuclear power plant, a plurality of procedures are involved, and there is a strict operation sequence between the procedures. Once a mistake is made, it will cause serious consequences. The preset procedure sorting rule refers to a procedure sorting rule set in advance. The procedure sorting rule can be set according to the actual situation, and can also be modified according to the actual situation. The procedure data includes at least one procedure. Here, the procedure refers to an operation item in the operation process. The operation process of a nuclear power plant work order involves at least one operation item. The procedure sorting result includes the sorting number of each procedure. The procedure risk information includes operation prompt information and / or safety measure information. Different procedures correspond to different procedure risk information. The nuclear power plant staff can click to view the procedure risk information corresponding to each procedure on the nuclear power plant work order page of the client, and confirm it. Only when the nuclear power plant staff confirms the procedure risk of each procedure, can the ticket taking operation be performed.

[0033] S40, based on the first confirmation information of the seal risk information and the second confirmation information of the procedure risk information, control the execution state of the nuclear power plant work order.

[0034] It can be understood that the first confirmation information is generated according to the confirmation operation of the user on the client on the plurality of seal risk information. The second confirmation information is generated according to the confirmation operation of the user on the client on the plurality of procedure risk information according to the procedure sorting result. The execution state refers to the operable state of the nuclear power work order. The operable state includes but is not limited to the ticket taking state and the ticket returning state.

[0035] In steps S10-S40, the nuclear power plant work order data is obtained; the nuclear power plant work order data includes seal data and procedure data; image recognition is performed on each electronic seal in the seal data to obtain an image recognition result; and based on the image recognition result, corresponding seal risk information is matched for each electronic seal to enable the user to perform confirmation operation on a plurality of seal risk information on the client; based on a preset procedure sorting rule, each procedure in the procedure data is sorted to obtain a procedure sorting result; and corresponding procedure risk information is matched for each procedure to enable the user to perform confirmation operation on a plurality of procedure risk information on the client according to the procedure sorting result; based on the first confirmation information of the seal risk information and the second confirmation information of the procedure risk information, the execution state of the nuclear power plant work order is controlled. The embodiment performs image recognition on the seal data one by one, provides risk prompts corresponding to the seal data, and matches corresponding procedure risk information for each procedure in the procedure data, thereby controlling the risk from different angles, avoiding misoperation caused by human error, and improving the flexibility and timeliness of nuclear power plant risk control.

[0036] Optionally, the image recognition result includes a plurality of seal classification results.

[0037] In step S20, i.e., the image recognition is performed on each electronic seal in the seal data, and an image recognition result is obtained, including:

[0038] S201, performing size conversion and image preprocessing on the seal image of the electronic seal to obtain a preprocessed seal image;

[0039] S202, performing seal feature extraction on the preprocessed seal image by a seal recognition model to obtain seal features of the preprocessed seal image;

[0040] S203, performing seal classification on the seal features to obtain a seal classification result.

[0041] It can be understood that the seal classification result is a classification result of the electronic seal. The classification result includes a seal classification type, such as a modification project, a sensitive area, an important area, and the like. The size conversion of the seal image of the electronic seal refers to a process of converting the seal image into a preset size. The preset size is a size set in advance, and the size conversion is for better image recognition. The image preprocessing of the seal image of the electronic seal refers to image enhancement, image segmentation, image restoration, and the like. This process is to improve the visual effect of the image so as to better perform image recognition. The preprocessed seal image refers to an image obtained by performing size conversion and image preprocessing on the seal image. The seal recognition model refers to a neural network model that has been trained and is used for recognizing seals. The seal features refer to features of the preprocessed seal image. The seal classification is performed on the seal features by the seal recognition model, the preprocessed seal image is classified into a seal classification type corresponding to the seal features, and the seal classification result is obtained.

[0042] In this embodiment, the image recognition is performed based on the seal image that has been subjected to size conversion and image preprocessing, and the accuracy of the image recognition is improved.

[0043] Optionally, in step S20, i.e., based on the image recognition result, corresponding seal risk information is matched for each electronic seal, including:

[0044] S204, obtaining a seal classification type corresponding to a target electronic seal from the image recognition result;

[0045] S205, traversing a seal risk library to query seal risk information corresponding to the seal classification type.

[0046] It can be understood that the seal risk information is used to realize the seal classification result, and the seal classification type is obtained from the image recognition result. The seal risk library includes a plurality of seal risk information corresponding to the seal classification type. According to the seal classification type, the corresponding seal risk information can be quickly and accurately obtained from the seal risk library, and the corresponding risk prompt is performed, thereby improving the flexibility and timeliness of the nuclear power plant risk control.

[0047] Optionally, the seal risk information includes a seal risk level and seal prompt information.

[0048] After step SS205, that is, after the seal risk library is traversed to query the seal risk information corresponding to the seal classification type, the following steps are included:

[0049] S2051, determining whether the seal risk level is greater than or equal to a seal level threshold value;

[0050] S2052, when the seal risk level is greater than or equal to the seal level threshold value, performing special effect rendering on the seal prompt information to obtain rendered seal prompt information;

[0051] S2053, displaying the rendered seal prompt information on the client for the user to perform a confirmation operation on the rendered seal prompt information on the client.

[0052] It can be understood that the seal risk level refers to the risk level of the seal image. The seal level threshold value refers to a pre-set seal level. The special effect rendering refers to a process of adding special effects to the seal prompt information for rendering. The special effects can be bold font and red font, etc. In this embodiment, for the seal image whose seal risk level is greater than or equal to the seal level threshold value, the seal prompt information corresponding to the seal image is rendered with special effects and then displayed on the client, so that the user can quickly understand the seal prompt information of the seal image, thereby improving the timeliness of the nuclear power plant risk control.

[0053] Optionally, the procedure sorting result includes a plurality of sorting numbers.

[0054] In step S30, that is, the procedures in the procedure data are sorted based on the pre-set procedure sorting rule to obtain a procedure sorting result, including:

[0055] S301, determining whether there is a procedure parallel to the target procedure in the procedure data;

[0056] S302, if there is a procedure parallel to the target procedure in the procedure data, merging the target procedure and the procedure parallel to the target procedure to obtain a merged procedure;

[0057] S303, sequencing the merging procedure to obtain a sequence number of the merging procedure.

[0058] It can be understood that the preset procedure sequencing rule refers to a pre-set sequencing rule, which can be set according to actual conditions. The target procedure can be any procedure contained in the procedure data. In this embodiment, the procedures in the procedure data are merged to make the arrangement of the procedures contained in the procedure data more clear and accurate, thereby avoiding the problem of procedure implementation error caused by human error and improving the accuracy of nuclear power plant risk control.

[0059] Optionally, in step S40, the first confirmation information based on the seal risk information and the second confirmation information based on the procedure risk information control the execution state of the nuclear power plant work order, including:

[0060] S401, judging whether the first unconfirmed information of the electronic seal exists in the first confirmation information, and judging whether the second unconfirmed information of the procedure exists in the second confirmation information;

[0061] S402, when the first unconfirmed information of the electronic seal does not exist in the first confirmation information and the second unconfirmed information of the procedure does not exist in the second confirmation information, the execution state of the nuclear power plant work order is controlled to update to be able to take tickets; so that the user takes the ticket operation on the nuclear power plant work order in the client.

[0062] It can be understood that the first unconfirmed information refers to the information generated by not detecting the confirmation operation of the user on the seal risk information in the client. For example, when the user cancels the confirmation or fails in the confirmation operation on the seal risk information in the client, the first unconfirmed information will be generated. The second unconfirmed information refers to the information generated by not detecting the confirmation operation of the user on the procedure risk information in the client. For example, when the user cancels the confirmation or fails in the confirmation operation on the procedure risk information in the client, the second unconfirmed information will be generated. In this embodiment, only when all the seal risk information and all the procedure risk information are confirmed successfully, the execution state of the nuclear power plant work order is updated to be able to take tickets, that is, only when the user confirms all the seal risk information and all the procedure risk information one by one, the ticket can be taken, which improves the timeliness and accuracy of the nuclear power plant risk control.

[0063] Optionally, the execution state includes the ability to take tickets and the ability to return tickets.

[0064] It can be understood that when the nuclear power plant work order is available for ticketing, the user can perform a ticketing operation on the nuclear power plant work order. When the nuclear power plant work order is available for ticketing, the user can perform a ticketing operation on the nuclear power plant work order. According to the execution state of the nuclear power plant work order, the corresponding implementation measures can be taken on the nuclear power plant work order, which can improve the accuracy of nuclear power plant risk control.

[0065] Optionally, the seal prompt information includes risk analysis information and corresponding preventive measures; the seal prompt information can be viewed, downloaded and printed.

[0066] It can be understood that the risk analysis information refers to the information of the risk analysis of the seal image. In this embodiment, the nuclear power plant staff can view the seal prompt information at any time to enhance the risk awareness. At the same time, the seal prompt information can be downloaded and printed for learning, etc., to improve the flexibility and accuracy of nuclear power plant risk control.

[0067] It should be understood that the size of the serial number of each step in the above embodiments does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
