Description

Technical Field

[0001] The present application relates to the technical field of nuclear power plants, and in particular to a portable isolation ticket execution system and method for passive nuclear power units. Background Art

[0002] Nuclear power is a highly complex industrial system. When problems arise during operation, strict procedures must be followed to ensure the safe operation of the nuclear power plant. Maintenance operations on passive nuclear power units in nuclear power plants require risk isolation before repairs or replacements can be performed. When operational defects are discovered during nuclear power plant operation, they are first reported to the main control center. Engineers with relevant expertise, the work supervisors, verify the defects and propose a repair plan. The next step is to go to the isolation office to establish a safety perimeter—the area that will be isolated for maintenance of the equipment in question—and then print out an isolation ticket. The isolation ticket must first be reviewed and signed by the main control center. It is then reviewed and approved by the shift supervisor and handed over to the appropriate on-site post for isolation. The isolation ticket is then returned to the main control center for inspection, confirmation, and stamping. It is then returned to the isolation office for confirmation and ultimately issued a work permit. Only with a work permit can maintenance begin.

Furthermore, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0046] This application proposes a portable isolation ticket execution system for passive nuclear power units (hereinafter referred to as the isolation ticket execution system). The isolation ticket execution system can be run on electronic devices, which is convenient for users to carry to the site to perform corresponding isolation tasks. Figure 1 The isolation ticket execution system includes an isolation task packaging module 100, an isolation task subcontracting module 101 and an isolation task execution module 102, wherein:

[0047] The isolation task packaging module 100 is used to display the packaging page for the isolation task to be packaged. When the isolation task to be packaged is reviewed and approved, the status of the isolation task to be packaged is adjusted to waiting for collection; the packaging page includes an isolation ticket list area for selecting isolation tickets, a reference file list area for selecting reference files, an audit object selection area, a task package basic information display area and a subcontractor selection area.

[0048] In one embodiment, the isolation ticket execution system also includes a task preparation module, which is used to create an isolation task. After the isolation task is created, the status of the newly created isolation task is adjusted to a waiting package. For example, the task preparation module can display an isolation task creation page, through which the task name, unit information (indicating which target unit in the nuclear power plant the newly created isolation task is associated with), system information (indicating which target system in the nuclear power plant the newly created isolation task is associated with), task description, packager (such as the role of the isolation manager), specification information (indicating whether it is related to the specification, and the specific related specification) and other basic information of the task package are obtained.

[0049] For example, the isolation task creation page is as follows Figure 2 As shown, the task creation user can enter the task name "CVSHI0521" on the page, select the target unit "HY1" and the target system "CVS" in the nuclear power plant associated with the new isolation task, select the new isolation task related to the specification, select the specific related specification by clicking the "View Work Order" button, and select the packager corresponding to the new isolation task as user A based on the business familiarity (equivalent to the role of isolation manager in the paper process of isolation ticket).

[0050] When detecting Figure 2 When the "Submit" button is clicked, the creation of the new isolation task is confirmed to be complete, and the status of the new isolation task is adjusted to the waiting package. Figure 3As mentioned above, a new task named "CVSHI0521" is added to the task list of user A. Figure 3 When the trigger operation of the "Operation" button 301 is clicked, the package assembly page for the "CVSHI0521" package isolation task is displayed, such as Figure 4 As shown, it includes the isolation ticket list area 401, the reference file list area 402, the audit object selection area 403, the task package basic information display area 404 and the subcontractor selection area 405. When a trigger operation is detected for the "Add" button in the isolation ticket list area 401, the isolation ticket selection area (such as Figure 5 As shown), select one or more target isolation tickets associated with the "CVSHI0521" package isolation task, where the isolation tickets displayed in the isolation ticket selection area are all currently unoccupied isolation tickets, indicating that these isolation tickets are waiting to be executed.

[0051] Furthermore, through the reference file list area 402, select some reference files related to this task (such as background files, reference documents, procedures, drawings, photos, etc.), through the audit object selection area 403, select who will perform the approval of this task, through the task package basic information display area 403 to display the basic information of the task package, and through the subcontractor selection area 405, select the subcontractor user B (the subcontractor can be the same as or different from the upper-level user A). If user A completes the packaging of the isolation task "CVSHI0521" to be packaged, click Figure 4 Click the "Submit" button in the task list, and the isolation task package module will push the task "CVSHI0521" to the approval object. After the review is completed, the status of the isolation task "CVSHI0521" to be packaged will be adjusted to waiting for collection.

[0052] Alternatively, user A can click on the task according to the needs (for example, user A thinks that the task does not need to be performed). Figure 4 Click the "Abort" button to abort the task; or, user A can click "Abort" according to the needs (for example, user A thinks that the basic information of the task package is incorrect). Figure 4 Click the "Back" button to roll back the task to the previous level where the user was created.

[0053] Continue to see Figure 4 When any isolated ticket in the isolated ticket list area 401 is selected, it also supports the management operations of deleting, editing and grouping any isolated ticket. For example, when user A clicks the "Edit" button in the isolated ticket list area 401, the isolated ticket editing page (such as Figure 6As shown in FIG401 , the isolation ticket editing page displays the original risk analysis and risk measures (for example, what operation to perform on a certain nuclear power equipment). After reviewing the original risk analysis and risk measures, if user A believes there are any errors, he or she can enter new risk analysis and risk measures on the isolation ticket editing page to obtain a new target isolation ticket. When user A clicks the "Group" button in the isolation ticket list area 401, the isolation ticket grouping information editing page is displayed, and the execution order of multiple isolation steps in the target isolation ticket can be sorted through the isolation ticket grouping information editing page.

[0054] The isolation task subcontracting module 101 is used to display the subcontracting page for the isolation task to be received. The subcontracting page is used to select team members and their role types, group the team members, and determine the isolation steps of each group in the target isolation ticket corresponding to the isolation task to be received.

[0055] For example, continue to undertake Figure 4 In the example shown, assuming that the isolation task to be received is the aforementioned task "CVSHI0521", subcontractor user B logs in to the isolation ticket execution system, can receive task "CVSHI0521", and trigger the display of the subcontracting page for task "CVSHI0521". User B uses the subcontracting page to select the team members who will perform the isolation task and the role types of the team members, such as executor, verifier, and main role. Among them, after user B receives task "CVSHI0521", user B is the main role of the task by default. In addition, the selected team members can also be grouped through the subcontracting page. A group includes at least two members, executor and verifier. Executors and verifiers have a one-to-one correspondence, that is, if there is an executor, there must be a corresponding verifier.

[0056] When there is only one target isolation ticket associated with the task "CVSHI0521", different groups can be assigned to different isolation steps of the target isolation ticket; when there are multiple target isolation tickets associated with the task "CVSHI0521", different groups can be assigned to different target isolation tickets and different isolation steps of different target isolation tickets. After completing the subcontracting work of the task "CVSHI0521" through the subcontracting page, all team members can log in to the isolation ticket execution system and sign the task "CVSHI0521". If any group of team members completes the signature, the status of the task "CVSHI0521" will be adjusted to pending execution without waiting for all team members to complete the signature. Subsequently, any group of team members can bring electronic devices (such as tablets) to the site to perform isolation tasks.

[0057] In one embodiment, the role types of the team members include executors, verifiers and main roles. The system also includes a shift handover management module, which is used to perform freeze management or change the main role management of the target isolation task. Among them, freeze management is to roll back the target isolation task to the user of the previous level, and the user of the previous level will reselect a new subcontractor, and the new subcontractor will reselect a new team member to re-execute the target isolation task; or, freeze management can also be to terminate the target isolation task. Change the main role management, which is used to change the main role among the team members corresponding to the target isolation task. For example, if the original main role of the target isolation task cannot continue to manage the target isolation task due to personal reasons, the new main role and approver can be selected through the shift handover management module. When the approver approves, the main role change is completed.

[0058] The entire process of executing the isolation task in the embodiment of the present application may include, in order:

[0059] Step 1: The user creates an isolated task and the task status is adjusted to "Pending Package Assembly";

[0060] Step 2: The package user (such as the quarantine manager) receives the newly created quarantine task, packages the newly created quarantine task, and adjusts the task status to "pending";

[0061] Step 3: The main character receives the completed isolation task (called the pending isolation task), selects the team members who will receive the pending isolation task, the team members' role types, and groups the team members. Each team is assigned the isolation steps to be performed in the pending isolation task, completing the subcontracting.

[0062] Step 4: Team members perform isolation tasks.

[0063] The above-mentioned target isolation task is an isolation task that has completed subcontracting (including isolation tasks to be executed and isolation tasks in execution), and the above-mentioned upper-level user is the package user (such as the isolation manager). When the main role believes that the target isolation task cannot be executed at present due to some objective reasons (such as the lack of on-site conditions or changes in plans), the target isolation task can be rolled back to the package user, and the package user will make further judgments. When the package user receives the rolled back target isolation task, if he believes that the task can be directly omitted, he can terminate the target isolation task through the shift handover management module and enter the reason for the termination; or, if the package user believes that although the task cannot be executed now, it can continue to be executed after a certain point in time, he can re-select a new subcontractor after a certain point in time, and the new subcontractor will re-select new team members to re-execute the target isolation task.

[0064] The isolation task execution module 102 is configured to display an isolation operation page for the isolation task to be executed, receive execution record data through the isolation operation page, and write the execution record data to a preset storage area. The isolation operation page includes an isolation operation work order area and a group execution prompt area, which displays the correspondence between each group and the isolation step. The preset storage area can be a pre-designated database, a designated block node in a blockchain network, a designated cloud storage node, or any other area capable of storing data, which is not specifically limited in this application.

[0065] In one embodiment, the above-mentioned isolation operation work order area includes a group screening area and an isolation task execution module, and is also used to display the isolation steps corresponding to the target group in the isolation operation work order area when a screening operation for the target group is detected in the group screening area.

[0066] As a feasible way, when the team members arrive at the site to prepare to perform any isolation task to be performed, they can log in to the isolation ticket execution system through the electronic device they carry, triggering the isolation task execution module to display the isolation operation page for any isolation task to be performed. For example, the isolation operation page is as follows: Figure 7 As shown, it includes an isolation operation work order area 70 and a group execution prompt area 71. The isolation operation work order area 70 displays an isolation operation work order 700 generated according to the isolation ticket corresponding to the isolation task to be executed, as well as a group screening area 701. Team members can view the isolation steps to be executed by their team members in this task through the group execution prompt area 71, and filter their own isolation steps to be executed through the group screening area 701. In the actual production of nuclear power plants, an isolation work order often involves a large number of isolation steps. If the teams are not distinguished, all of them will be displayed in the isolation operation work order area. On the one hand, team members need to spend a lot of time manually looking for their own isolation steps to be executed. On the other hand, due to human factors, it is easy for teams to mistakenly execute the isolation steps of other groups. The embodiment of the present application adopts such a method, which allows team members to quickly locate their own isolation steps to be executed without being disturbed by the isolation steps of other teams.

[0067] In one embodiment, the isolation operation worksheet includes an execution entry for the device to be operated, and the isolation task execution module is further used to obtain the latest device status of the device to be operated from a preset storage area, and distinguish and display the execution entries according to the latest device status and the expected operation to be performed on the device to be operated. Among them, one execution entry corresponds to one isolation step in the isolation task to be executed. Figure 7As described above, for the device to be operated with the device code "HY1-XX1", the expected operation that the team members need to perform in the isolation task to be performed is "off", which is different from the current latest device status of the device "on", which means that the team members need to perform a valid operation on the device to be operated "HY1-XX1" and adjust it from the status "on" to off. Then, the execution entry where the device to be operated "HY1-XX1" is located is displayed separately, and the background color of the areas where the fields "Scan QR code", "HY1-XX1", "off" and "execute" of the execution entry where the device to be operated "HY1-XX1" is located are filled with gray. The expected operation of the devices to be operated "HY1-XX2" and "HY1-XX3" is the same as the current latest device status of the corresponding devices, indicating that the team members do not need to perform operations on these two devices during the execution of the isolation task to be performed, and the background color area of ​​the execution entries where they are located remains white. It is understandable that the specific method of distinguishing and displaying execution entries can be distinguished by displaying different background colors of the area where the execution entries are located as shown in the above example, or other methods such as font color, font size, etc. can be used. This application does not make specific limitations on this.

[0068] In one embodiment, the execution entry includes an execution mark area, which is used to trigger the execution of one or more of the following functions: execution mark, revocation, acquisition and addition of execution notes, acquisition and upload of attachments, acquisition and inapplicability of execution triggering operations. Figure 7 As shown, three execution items are displayed, one execution item corresponds to one isolation step, and each execution item includes an execution mark area 702. When the isolation step represented by any execution item is not executed, a mark "□" is displayed in the execution mark area 702. When the isolation step represented by any execution item is completed, the team member clicks the mark "□", and the isolation task execution module updates the execution mark "□" displayed in the execution mark area 702 to a mark "○", thereby completing the execution mark function.

[0069] Alternatively, during the execution of the isolated task, the team members can trigger the display of the execution mark area (such as clicking the right button of the mouse, long pressing the execution mark area 702, etc.) to display the execution notes, upload attachments and the function button of not applicable execution (N / A), such as Figure 8As shown in area 703 of the . During the execution process, if a team member believes that there are any abnormalities in the nuclear power plant equipment, they can trigger the "Execution Notes" button to add a note, trigger the "Upload Attachment" button to upload an attachment, or directly upload a photo (such as a photo of the padlock after any isolation step is completed). Alternatively, if a team member believes that the conditions for executing any isolation step are not met on site, they can click the (N / A) function button to indicate that the isolation step will not be executed at this time. Accordingly, the execution mark displayed in the execution mark area 702 corresponding to the isolation step will be updated from "□" to "N / A".

[0070] In one embodiment, the isolation task execution module is also used to provide an audio and video conferencing function so that it can be called during the execution of the isolation task to be executed. Exemplarily, the isolation task execution module can display the calling entry of the audio and video conferencing function in the isolation operation page. If the team members encounter some abnormal situations that they cannot judge during the task execution, they can start the audio and video conferencing function through the calling entry, create a meeting, and invite participants to synchronize the on-site situation through the audio and video conference, and hold a meeting to discuss solutions. During the audio and video conference, the isolation task execution module also provides a small whiteboard function for writing directly on the conference screen during the audio and video conference.

[0071] In one embodiment, the isolation ticket execution system also includes a database function module, which is used to display a device status page based on the historical execution record data in the preset storage area. The device status page includes one or more of the following information of the nuclear power plant equipment: device identification, device status, generation time, and work package source. Users can view the changes in the device status of each nuclear power plant device over time by displaying the device status page, so as to assist users in determining whether an abnormality has occurred in the nuclear power equipment. For example, the above-mentioned device status page can be as follows: Figure 9 As shown, assuming that the pre-set lower limit boundary value for the target nuclear power plant equipment with the equipment code HY1-XX4 is 5000mPa (milliPascal), the user can check through the device status display page that although the latest equipment status of the target nuclear power plant equipment is still not less than or equal to 5000mPa, it is getting closer and closer to the boundary value over time. In this case, it can be predicted in advance that the target nuclear power plant equipment may have an abnormality and certain processing measures can be taken without waiting until the value falls below the lower limit boundary value.

[0072] In one embodiment, the database function module is further configured to monitor the state change trend of nuclear power plant equipment based on historical execution record data, and output an alarm message if the state of any nuclear power plant equipment is detected to be gradually approaching a corresponding boundary value. The boundary values ​​included in the historical execution record data may be upper boundary values ​​and / or lower boundary values. If the state of any nuclear power plant equipment is detected to be decreasing over time, gradually approaching the lower boundary value, or increasing over time, gradually approaching the upper boundary value, it is determined that the equipment state is gradually approaching the corresponding boundary value, and an alarm message is output.

[0073] In one embodiment, the isolation task execution module is also used to download the execution information required for the offline execution of any isolation task to the local computer before any isolation task is executed offline, and the execution information includes the isolation operation work order. Furthermore, after the offline execution of any isolation task is completed, the offline execution record data is received, and the offline execution record data is stored in the above-mentioned preset storage area. Nuclear power is a very complex industrial system, and the network conditions at the isolation task execution site are also different. Before executing the isolation task, if the team members know in advance that the network conditions at the execution site are not good, they can download the execution information required for the task (such as the isolation operation work order, the correspondence between the team members and the isolation steps) to the local computer in advance through the isolation task execution module. Subsequently, during the task execution process, the isolation task execution module can display the isolation operation page according to the locally downloaded execution information, receive the offline execution record data through the isolation operation page, and store the offline execution record data locally. After the task execution is completed, the team members will upload the offline execution record data again, the isolation task execution module receives the offline execution record data, and stores the offline execution record data in the above-mentioned preset storage area.

[0074] The portable isolation ticket execution system for passive nuclear power units provided in this application digitizes the entire isolation task process through interactive interfaces provided by the isolation task packaging module, isolation task subcontracting module, and isolation task execution module, making it easy to operate. Furthermore, it supports the group execution of isolation tasks, improving the efficiency of isolation task execution.

[0075] See Figure 10 The present application proposes a method for executing a portable isolation ticket for a passive nuclear power unit, which is used to implement all the functions that the above system can implement. The method includes:

[0076] S1001: Display the package assembly page for the isolation task to be packaged. After the isolation task to be packaged is reviewed and approved, the status of the isolation task to be packaged is adjusted to waiting for collection; the package assembly page includes an isolation ticket list area for selecting isolation tickets, a reference file list area for selecting reference files, an audit object selection area, a task package basic information display area and a subcontractor selection area.
