[0043] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0044] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0045] In order to facilitate understanding of the present invention, the present invention will be described more fully below, and the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0046] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present invention, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. It is not necessarily required or implied that there is any such actual relationship or order between these entities or operations.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0048] In a preferred embodiment, reference Figure 1 The management method of temporary control change of a nuclear power plant in this embodiment includes the following steps:

[0049] S10, determine the TCA work order, and push the approval process for the TCA work order based on the corresponding preset work order linkage approval process, and obtain a first approval result. The TCA work order includes TCA basic information and TCA operation license information, and the preset work order approval process includes at least one approval node.

[0050] S20. When the first approval result is passed, determine the TCA operation sheet, push the TCA operation sheet through the approval process based on the corresponding preset operation sheet linkage approval process, and obtain the second approval result. When the second approval result is passed, execute step S30. The TCA operation sheet includes a TCA installation notice sheet and a TCA removal notice sheet. The preset operation sheet linkage approval process includes multiple approval nodes.

[0051] S30. Close the TCA work order and TCA operation order.

[0052] Furthermore, in step S10 of determining the TCA work order, it includes:

[0053] Receive the TCA type determined by the TCA person in charge from the first terminal, and determine the TCA work order according to the TCA type. Among them, the TCA type includes random TCA and scheduled TCA. It can be understood that temporary control changes are divided into two categories, one is scheduled TCA: temporary control changes for periodic installation and cancellation. The other is random TCA: temporary control changes for non-periodic installation and cancellation.

[0054] Specifically, the TCA work order includes a random TCA work order and a scheduled TCA work order. The step of determining the TCA work order according to the TCA type includes:

[0055] When it is determined to be a random TCA, the work order information input by the TCA person in charge is received from the first terminal to form a random TCA work order. When it is determined to be a scheduled TCA, the production work order information is obtained from the ERP system to form a scheduled TCA work order.

[0056] That is to say, for preventive projects, work orders are automatically generated and the scheduled TCA process is manually initiated; for corrective projects, work orders are manually created and the random TCA process is manually initiated.

[0057] This embodiment standardizes the management of TCA, effectively improves the timeliness and accuracy of TCA management, and improves the TCA management level of nuclear power plants. Data integration is achieved in the nuclear power plant office intranet, which optimizes business processes, improves work efficiency, reduces labor costs, and reduces the risk of human error.

[0058] In some embodiments, the preset operation list linkage approval process includes an installation assessment approval process, a demolition assessment approval process, and a demolition closure approval process, and the installation assessment approval process, the demolition assessment approval process, and the demolition closure approval process all include at least one approval node. Figure 2 In step S20, the TCA operation sheet is pushed for approval based on the corresponding preset operation sheet linkage approval process, and the second approval result is obtained, including:

[0059] S201. Push the approval process of the TCA operation sheet based on the corresponding installation assessment approval process, and obtain the installation assessment approval result.

[0060] S202, determine whether the installation assessment approval result is passed. If not, re-determine the TCA work order. If yes, receive the installation information entered by the person in charge when implementing the TCA installation from the terminal corresponding to the person in charge of the work, and send a reminder message of the installation information entry progress to the person in charge of the TCA at regular intervals through the first terminal.

[0061] S203: Push the approval process of the TCA operation sheet based on the corresponding demolition assessment approval process, and obtain the demolition assessment approval result.

[0062] S204, determine whether the demolition assessment approval result is passed. If so, the demolition information entered by the person in charge when implementing the demolition TCA is received from the terminal corresponding to the person in charge. It can be understood that since the approval nodes in the demolition assessment approval process are linked and transferred, the current node will not flow to the next approval node until it is approved. Therefore, the demolition assessment approval result of this embodiment may refer to the approval result of the last approval node in the demolition assessment approval process. Similarly, the same is true for the installation assessment approval result.

[0063] S205: Push the approval process for the TCA operation sheet based on the corresponding dismantling and closing approval process, and execute step S30 when receiving the dismantling and closing confirmation result.

[0064] In a specific embodiment, Figure 3a and Figure 3b This is a random TCA approval flow chart of this embodiment. Figure 4 The following is a flowchart of the timed TCA approval process of this embodiment. Figure 3a and Figure 3b Provide detailed explanation of random TCA approval.

[0065] The TCA person in charge initiates a temporary control change process according to the needs of the nuclear power plant due to special system status requirements, temporary design improvements or lack of spare parts, etc. The login information input by the TCA person in charge is received from the first terminal to initiate the approval process.

[0066] First, select a random TCA type to determine the corresponding TCA work order (fill in basic information at node 110), and follow Figure 3a and Figure 3b The specific contents of the TCA work order are as follows: Figure 6 As shown in the figure, it includes TCA basic information and TCA operation license information. TCA basic information can include TCA application subject, applicant information, process priority, current node status, etc. After the TCA work order is approved, the TCA operation order approval process will be entered (as shown in the figure node 125 to node 325). The specific content of the TCA operation order is as follows Figure 7 As shown in the figure, it includes TCA installation notice, TCA removal notice, TCA validity period, etc. After the operation process is approved to node 150, the work supervisor implements the installation on site and enters the information. The TCA supervisor tracks the progress and enters the information (node ​​155). If necessary, the extension application process is initiated (such as Figure 5 As shown), the validity period will be automatically updated after the extension is successful. After the conditions for removal are met, the operation process approval will be transferred to the person in charge of node 320 to carry out the removal and enter the information on site. The system will automatically verify and confirm that it is consistent with the information before installation before approval and submission. After the TCA is removed, the review is closed and automatically archived.

[0067] The preset work order approval process of this embodiment includes two approval nodes (node ​​115 and node 120). It should be noted that when the implementation department coordination and approval is completed at node 120, the system automatically releases the TCA work order.

[0068] The installation assessment approval process of this embodiment includes thirteen approval nodes (node ​​120, node 135, node 136, node 137, node 138, node 139, node 140, node 141, node 142, node 143, node 144, node 145, node 146) that are linked in sequence. When node 130 is reviewed and approved by the TCA management engineer, it enters nodes 135, node 136, node 137 and node 138, and when all four nodes are approved, it enters node 139. When the approver chooses not to report to the Nuclear Safety Administration at node 137, node 139 is automatically skipped. After the TCA application department submits the application to the National Nuclear Safety Administration for approval at node 139, the implementation department coordinates and arranges the installation, and the system automatically releases the linkage work order (node ​​140). If the approval result of node 139 is not passed, the process ends, the system releases the TCA work order, and closes the TCA work order and TCA operation order. After nodes 141 to 146 are approved in sequence, the installation information entered by the person in charge when implementing the installation of TCA is received from the terminal corresponding to the person in charge of the work, and a reminder message of the installation information entry progress is regularly sent to the person in charge of TCA through the first terminal (nodes 150 and 155). After the person in charge of TCA confirms that the conditions for demolition are met, the demolition assessment approval process (nodes 305 to 315) is entered, and when all nodes are approved, the demolition information entered by the person in charge when implementing the demolition of TCA is received from the terminal corresponding to the person in charge of the work. Next, based on the corresponding demolition closure approval process (nodes 323 and 325), the approval process is pushed for the TCA operation sheet, and when the demolition closure confirmation result is received, step S30 is executed, that is, the notification sheet and the work sheet are linked to the closed state.

[0069] It should be noted that the 130 node is for the TCA management engineer of the centralized management department to review compliance to ensure compliance with the company's management requirements. YSE approval refers to the review by the equipment management engineer from the perspective of equipment management. YEN approval refers to the review by the modification engineer from the perspective of equipment modification. STA approval refers to the review by the safety consultant from the perspective of nuclear safety.

[0070] This embodiment standardizes the management of TCA, effectively improves the timeliness and accuracy of TCA management, and improves the TCA management level of nuclear power plants. Data integration is achieved in the nuclear power plant office intranet, which optimizes business processes, improves work efficiency, reduces labor costs, and reduces the risk of human error.

[0071] Furthermore, in the execution step of S202, it also includes:

[0072] A pre-expiration reminder message is sent to the person in charge of TCA via the first terminal. When the number of extensions does not exceed the preset number, it is determined whether the extension application confirmation instruction input by the person in charge of TCA is received from the first terminal. If so, the extension risk assessment form is determined, and the approval process of the extension risk assessment form is pushed based on the preset extension assessment linkage approval process, and the third approval result is obtained. The extension assessment linkage approval process includes multiple approval nodes. It is determined whether the third approval result is passed. If so, the corresponding TCA validity period is automatically updated.

[0073] In a specific embodiment, Figure 5 The following is a flowchart of the TCA extension application approval process of this embodiment. First, the TCA person in charge initiates the extension process according to the survival status of the TCA. The extension application confirmation instruction input by the TCA person in charge can be received from the first terminal. Then, enter node 205 to determine the extension risk assessment form. Specifically, the extension risk assessment form filled out by the TCA person in charge is received from the first terminal. After confirming that it is completed, enter the extension assessment linkage approval process (node ​​210 to node 225). When all approval nodes are approved, the system automatically updates the TCA validity period.

[0074] Furthermore, in step S20, determining the TCA operation list includes:

[0075] When it is determined to be a timed TCA, a preset template is called according to the user's input instruction, and the called template is automatically filled into the TCA operation form. Each template contains at least part of the data required by the TCA operation form.

[0076] It is understandable that the content of the scheduled TCA is relatively fixed, usually for temporary control changes commonly used in the routine up and down phases of the unit. In order to simplify the operation, the scheduled TCA initiation phase can be based on a form data in the preset template list, and the data can be automatically filled into the initiated form, thereby simplifying the operation. This embodiment realizes the one-key call of the basic information of the scheduled TCA through the template function, which can further improve work efficiency.

[0077] Furthermore, in step S20, determining the TCA operation list includes:

[0078] The creation instruction input by the user is received through the virtual button, and the TCA installation notice and the TCA removal notice are obtained according to the creation instruction. In other words, the installation notice and the removal notice can be automatically created during the form filling stage. This embodiment realizes the automatic creation of the installation notice and the removal notice with one key, realizes the opening of the work process generation system, and effectively improves work efficiency.

[0079] In another preferred embodiment, the server of this embodiment includes a memory and a processor, the memory stores a computer program, and the processor executes the steps of the management method of temporary control changes of nuclear power plants as in the above embodiment by calling the computer program stored in the memory.

[0080] The present invention standardizes the management of TCA, effectively improves the timeliness and accuracy of TCA management, realizes data interoperability in the nuclear power plant office intranet, optimizes business processes, improves work efficiency, and can reduce labor costs and human error risks.

[0081] In another preferred embodiment, reference Figure 8 The management system for temporary control changes of nuclear power plants in this embodiment includes multiple interactive terminals and a server as in the above embodiment. Multiple interactive terminals establish communication connections with the server through an internal network. In the figure, the S01 server can read the data written into the work order and the notice from the ERP server (S00 work process generation system server). In other words, this system can access the ERP server through the internal network to obtain the production work order information.

[0082] Optionally, the interactive terminal includes a computer terminal and / or a mobile terminal. The system realizes the connection between the computer terminal and the mobile terminal, which greatly improves the approval efficiency and convenience. The management system can also support form printing, report printing, computer terminal report management, etc.

[0083] The present invention standardizes the management of TCA, effectively improves the timeliness and accuracy of TCA management, realizes data interoperability in the nuclear power plant office intranet, optimizes business processes, improves work efficiency, and can reduce labor costs and human error risks.
