Technical Field

[0001] The present invention relates to the field of nuclear power plant safety management systems, and more particularly to a method and system for electronically displaying a nuclear power plant isolation license. Background Art

[0002] Paper documents for nuclear power plant isolation permits (also known as work permits) are stored on a physical ticket rack in the isolation office, arranged alphabetically by system equipment code. To retrieve a work permit, simply pull out the corresponding work permit package and browse through it. After the nuclear power plant implemented electronic isolation permit retrieval and return tickets and paperless isolation work packages, the existing physical ticket rack no longer reflects the status of permit retrieval, return, release, or suspension, making it impossible for isolation office staff to directly view the status of all work permits.

BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0041] Figure 1 It is a flow chart of the electronic display method of the nuclear power plant isolation license of the present invention. DETAILED DESCRIPTION

[0042] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0043] like Figure 1 As shown, Figure 1 The present invention provides an electronic display method for a nuclear power plant isolation license.

[0044] Step S1: Obtain basic information of a work ticket from a database; wherein the work ticket includes a work order, a work application form, and an isolation operation form;

[0045] In this step, it is necessary to explain:

[0046] Step S2: Classify the work order, work application form and isolation operation form to obtain classified work ticket information;

[0047] In this step, it is important to categorize the work orders, work requests, and isolation operation orders received. Work request information should be accurately categorized based on the alphabetical order of system equipment codes, work type (e.g., repair, commissioning), or urgency to facilitate subsequent targeted processing and review.

[0048] Step S3: Simplify the work order, work application form and isolation operation form to obtain simplified work ticket information;

[0049] In this step, it is important to note that redundant information in work orders, work application forms, and isolation operation forms should be removed, and only key content such as equipment name, work description, isolation status, etc. should be retained. The streamlined work order information is easier to understand and process, thereby improving work efficiency.

[0050] Step S4: Display the classified and simplified work ticket information to obtain an intuitive display result.

[0051] This step requires translating the categorized and simplified work order information into an intuitive visual interface. Work ticket status is indicated by different colors, such as red for urgent, yellow for in-progress, and green for completed. Work tickets can also be presented in a table format, listing equipment codes, work summary, and isolation operation points, allowing staff to clearly understand the details of all work tickets.

[0052] By centrally acquiring work ticket information from the database, data integrity and accuracy are ensured. Categorized processing streamlines work tickets, removes redundant information, and highlights key points, significantly improving the efficiency of nuclear power plants' isolation license management and reducing the time and cost of manual search and organization. An intuitive interface, after display processing, visualizes work ticket status and key information. Staff can quickly understand the status of all work tickets without having to read reams of paper documents or query the database, reducing the probability of error, improving decision-making speed and accuracy, and effectively ensuring the safe production and operational efficiency of nuclear power plants.

[0053] Furthermore, the work order includes: work order code, work application function location code, work order location and work order status;

[0054] The work application includes: work application number, work application short description, work application user status, work application system status and work application approval status information;

[0055] The isolation operation sheet includes: isolation operation sheet code, isolation operation sheet system status and isolation operation sheet function location information;

[0056] Step S2 includes:

[0057] Classify work tickets with a work order status of "not in progress", a work application form user status of "not abnormal" or "not suspended", a work application form system status of "prepared", and a work application form approval status of "approved" as pending tickets;

[0058] Classify work tickets with a system status of work order completed, a system status of work application form prepared, a work application form approval status of green, and a system status of quarantine operation form not released as tickets to be released;

[0059] Work tickets with a work order status of "in progress", a work application form system status of "prepared and not closed", a work application form user status of "application aborted" or "abnormal", a work application form approval status of "green light" and an isolation operation form system status of "not released" are classified as pending abort tickets.

[0060] In one embodiment, qualified work application information is captured from the database every five minutes to avoid system stalls and filter out work application information that meets specific criteria. For tickets waiting to be retrieved, the system filters out work application information based on the following criteria: the work order status is not "in progress," the work application system status is "prepared," the work application user status is not "abnormal" or "suspended," and the work application approval status is "green." For tickets waiting to be released, the filtering criteria are: the work order system status is "work completed," the work application system status is "prepared," the work application approval status is "green," and the quarantine operation system status is not "released." For tickets waiting to be suspended, the extraction criteria are: the work order status is "in progress," the work application system status is "prepared" and not "closed," the work application user status is "appointed" or "abnormal," the work application approval status is "green," and the quarantine operation system status is not "released." Furthermore, the system extracts work application information with a work order status of "in progress" to track and manage ongoing work.

[0061] Furthermore, step S3 includes:

[0062] Extract the unit code from the functional position code of the work application form to distinguish the unit to which the work ticket belongs.

[0063] In one embodiment, the function position code of the work application is extracted to separate the unit code, and the unit code to which the work ticket belongs is distinguished based on the extracted unit code.

[0064] In one embodiment, the system identifies the functional location code of the work request or work order, extracts the fourth character as the unit code for the work ticket, and records it to distinguish the unit to which the work ticket belongs. For example, extracting the fourth character from the functional location code "ND-1-24-ARE-057VL" yields the unit number "Unit 1."

[0065] Furthermore, step S3 further includes:

[0066] Extract the system code from the function location code of the work application form and count the number of work tickets in the same system.

[0067] In one embodiment, the system code is first extracted from the function location code of the work application form. The function location code is a code used to uniquely identify the functional location of the equipment in the nuclear power plant equipment system, and it contains information about the system to which the equipment belongs. By parsing the function location code, the system code representing the system to which the equipment belongs can be accurately extracted. Then, based on the extracted system code, the number of work tickets in the same system is counted. Specifically, the system will traverse all the obtained work ticket information, identify the system code in each work application form, and classify and count the work tickets according to the system code, thereby obtaining the number of work tickets in each system.

[0068] In one embodiment, the system identifies the function and location code structure of a work request and extracts characters from positions 9-11 from the function and location code as the system code for that work request. For example, the system code extracted from the function and location code "ND-1-24-ARE-057VL" is "ARE." The system then categorizes and counts the work requests and calculates the number of work requests within the same system.

[0069] Furthermore, the system code for extracting the function position code of the work application form includes:

[0070] Extract characters from 9th to 11th digits of the work application form's function position code as the system code.

[0071] In one embodiment, the function location code in a work request is a string of codes containing multiple information segments. For example, characters 9-11 are used exclusively to indicate the system code to which the device belongs. In actual operation, the system accurately locates characters 9-11 of the function location code and directly extracts these three characters as the system code.

[0072] Furthermore, the work application form ticket return control information includes: release from the quarantine office, release from the main control room, and direct release;

[0073] Step S3 further includes:

[0074] For a set of work application forms whose return control information is released by the quarantine office, information in the short description of the work application form that is not of concern to the quarantine office is removed.

[0075] In one embodiment, the return ticket control information of the work application form includes three types: release by the quarantine office, release by the main control room, and direct release. In step S3, for the set of work application forms whose return ticket control information is released by the quarantine office, the short descriptions of these work application forms will be further screened and processed. Specifically, the content in the short description of the work application form will be screened according to the preset range of information that the quarantine office is concerned about, and information that does not fall within the scope of the quarantine office's attention will be eliminated. This process helps to ensure that the staff of the quarantine office can focus on the key points related to their duties when processing work application forms, and avoid being disturbed by irrelevant information. As an option, in actual work, information such as historical maintenance records of equipment or non-critical parameter notes can also be eliminated, such as past failure time records of equipment, descriptions of equipment performance indicators that are not related to this work, etc.

[0076] In one embodiment, the system identifies work ticket short descriptions and excludes work tickets with specific character features. For example, work tickets containing the characters "[T0]" in the short description are not considered work tickets by the quarantine office and will be directly eliminated.

[0077] Furthermore, step S4 includes:

[0078] Under the same unit classification:

[0079] The work application form information for the quarantine office release in the ticket collection category will be displayed in yellow font;

[0080] The work application form information released from the main control room in the category of waiting for ticket collection will be displayed in orange font;

[0081] The work application information for direct release in the waiting ticket category is displayed in white font.

[0082] Through this differentiated display method, staff can quickly identify the return control type of the work application form based on the font color, thereby quickly understanding the processing requirements and priorities of different types of work application forms.

[0083] Furthermore, the work application form ticket return control information includes: ticket return locked, direct ticket return; the work status includes: in progress; step S4 also includes:

[0084] Under the same unit classification:

[0085] Display work application information with the status of "in progress" and the return control information of the work application form as "return locked" in yellow font;

[0086] The work application information with the work order status being in execution and the work application return control information being direct return will be displayed in white font.

[0087] In one embodiment, under the same unit classification, the system displays the work application form information in different color fonts according to the combination of the work order status and the return ticket control information. Specifically, when the work order status is "in execution" and the work application form return ticket control information is "return ticket locked", the system will display the corresponding work application form information in yellow font, prominently reminding the staff that the relevant work is in progress and the return ticket operation is subject to lock restrictions. Special attention should be paid to its progress and status to ensure that the return ticket does not occur due to erroneous operation before the work is completed. For work application form information whose work order status is also "in execution" but the work application form return ticket control information is "direct return ticket", the system will display it in white font, indicating that this type of work application form can be returned relatively directly if certain conditions are met, so that the staff can quickly identify the work application form with higher return ticket operation flexibility, so as to facilitate the timely processing of return ticket matters after the work is completed, thereby improving work efficiency.

[0088] Furthermore, the work order location includes the plant number;

[0089] Step S4 includes:

[0090] Count the number of work orders for each factory building according to the factory building number to obtain the work order quantity information corresponding to each factory building;

[0091] Under the same factory classification, set the corresponding display color according to the range of work order quantity for each factory.

[0092] In one embodiment, the plant number is extracted from each work order, and then work orders with the same plant number are counted, ultimately generating a statistical table covering all plants and their corresponding work order counts. Within the same plant category, the work order count for each plant is color-coded according to a preset range of counts. For example, plants with a low number of work orders are displayed in green, indicating a light workload; plants with a medium number of work orders are displayed in yellow, indicating a moderate workload; and plants with a high number of work orders are displayed in red, indicating a heavy workload that may require further attention or resource allocation.

[0093] In one embodiment, the work ticket list is formatted in a table format with a dark background color to reduce screen heat and avoid increasing light intensity in the isolated office. Due to the limited display area of ​​the display screen, the system only displays the most critical information on the work ticket to ensure simplicity and readability.

[0094] For the list of tickets to be picked up, the fields displayed include the WCA (work request form) number, functional location (prefixed with the unit number), short description and execution profession. The number of tickets to be picked up in the current system is counted in the upper right corner of each system code. Among them, the work tickets released by the isolation office are displayed in yellow font, the work tickets released by the main control room are displayed in orange font, the work tickets released directly are displayed in the system default white font, and the work tickets with "unavailable information" are indicated in italics. This design enables users to directly understand the number of tickets to be picked up in each system, the release method of the work tickets, a brief description of the content of the work tickets, and the responsible professional department.

[0095] The list of tickets to be released includes the WCA (Work Request) number, functional location (prefixed with the crew number), a short description, and the executing profession. An information bar has been added on the right side to record the return dates of the first three work tickets, reminding the quarantine manager to handle them as soon as possible to ensure work efficiency.

[0096] The information displayed on the ongoing maintenance work list includes the WCA (work request form) number, functional location (prefixed with the unit number), short description and execution specialty. The upper right corner of each system code counts the number of tickets currently waiting to be collected in this system. Due to the large number of work tickets being executed, an additional column will be added when the number of system codes on the left exceeds 10, and a maximum of 20 systems will be displayed. Yellow font is used to indicate that the return ticket is locked, the system default white font is used to indicate that the ticket can be returned directly, and italics are used to indicate that the work ticket contains "unavailable" information. When the number of work tickets is large and exceeds one screen, it will be scrolled to ensure the integrity and accessibility of the information.

[0097] Furthermore, to more intuitively reflect the distribution of ongoing maintenance work on-site, the system uses color on the main plant floor plan based on the room number and building code of the work order corresponding to the work request. The specific color scheme is as follows: if a building has no active maintenance work orders, the building is filled with light blue; if the number of work orders is 1 ≤ ≤ 20, the building is filled with green; if the number of work orders is 21 or more, the building is filled with brown. This visual representation method helps staff quickly understand the distribution of maintenance work in each building, improving management efficiency.

[0098] The present application also provides an electronic display system for an isolation license of a nuclear power plant, comprising a memory, a processor and a computer program stored in the memory, wherein the processor executes the computer program to implement the steps of any one of the above methods.

[0099] This invention solves the problem of work permits being difficult to visually display in the quarantine office after going paperless. By simplifying permit information and using statistically sound charts, it intuitively restores the functionality of a physical work permit rack, achieving a clear and accessible display. Furthermore, it makes full use of charts, fonts, and colors to intuitively display work permit collection and return control information, allowing quarantine managers to directly understand permit status.

[0100] It is understandable that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
