Description

Technical Field

[0001] The present invention relates to the technical field of nuclear power overhaul, and in particular to a nuclear power overhaul work order scheduling control method and system. Background Art

[0002] In the current nuclear power plant overhaul work, the overhaul planners need to analyze the planned start time and planned completion time of each work order based on the work content and the entire overhaul window during the scheduling process. During the overhaul implementation process, the work order implementation time is dynamically adjusted according to the overhaul progress.

[0003] There are about 6,000 to 8,000 work orders for a single overhaul. For a specific work order, planners need to collect data such as the work location, work content, isolation window, required maintenance time, planned margin, logical relationship, etc. of the equipment to be repaired, and then sort out and integrate more than 6,000 work orders according to these factors. During the overhaul implementation, these work orders are managed and controlled according to system requirements, main line progress, and logical relationships until the entire work order maintenance is completed, thus completing the entire scheduling and control of the work order.

[0004] Since there are many factors to consider when scheduling and controlling work orders, planners usually need to analyze the logical relationship between previous and subsequent work one by one and set the start and completion time. An experienced planning engineer needs about 5 to 10 minutes to complete a work order, which is inefficient and prone to human errors. Summary of the invention

[0005] The main purpose of the present invention is to provide a method and system for scheduling and controlling nuclear power overhaul work orders, so as to improve the efficiency of overhaul work order scheduling and control while also reducing the risk of human error.

[0006] Another object of the present invention is to provide a method and system for scheduling and controlling nuclear power overhaul work orders. During the preparation period, work orders of the same isolation window are summarized according to historical main isolation code information, and the maintenance plan duration of these work orders is determined in combination with the main line plan. The start and completion times are uniformly assigned through the system, and there is no need for planners to manually assign them one by one, thereby improving work efficiency.

[0007] Another object of the present invention is to provide a nuclear power overhaul work order scheduling control method and system. During implementation, the main isolation target completion time is tracked in real time according to the changes in the main line work, and timely warnings are issued for overdue work orders to remind staff to complete the maintenance project ahead of schedule.

[0008] Another object of the present invention is to provide a nuclear power overhaul work order scheduling control method and system, which aggregates the historical duration data of the same work order to facilitate planners to compile reasonable window maintenance time.

[0009] Another object of the present invention is to provide a nuclear power overhaul work order scheduling control method and system, so as to reasonably formulate manpower deployment arrangements during peak working periods and reasonably deploy personnel so that there are sufficient personnel during peak working periods and avoid wasting human resources during off-peak periods.

[0010] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] In one aspect, the present invention provides a method for scheduling and controlling a nuclear power overhaul work order, comprising:

[0020] Step 1.6: Set the work order start, completion time and margin according to the main isolation window.

[0021] In some embodiments, the keyword is modified as required as a new code search condition to find the target main isolation code, specifically including:

[0022] Select the corresponding device code according to the system code, device number, and device type source;

[0023] Select the corresponding equipment code according to the specialty of the work order;

[0024] Identify keywords for equipment names and work contents in the quota manual and recommend equipment codes;

[0025] Identify the device code corresponding to the unique entry;

[0026] For the same equipment code, based on the actual work content, the main isolation equipment code is automatically matched by comparing the equipment code, profession, and work content keywords with the historical database work order.

[0027] In some embodiments, the work order history information includes historical master isolation codes and work durations.

[0028] In some embodiments, step 2 specifically includes:

[0029] Step 2.1: Check whether the work order is completed according to the set main isolation code. If the work order status is completed, go to step 2.2; if the work order status is not completed, go to step 2.3;

[0030] Step 2.2: The work order status is completed, close the main isolation;

[0031] Step 2.3: Adjust the work order completion time and margin, and then check whether the work order is completed. Repeat step 2.1 until all work orders are completed.

[0032] Step 2.4: Release from quarantine as notified by the primary quarantine code.

[0033] On the other hand, the present invention also provides a nuclear power overhaul work order scheduling control system, comprising:

[0034] The data module is used to archive and store the information of all previous overhaul work orders and provide retrieval data for the query module;

[0035] A query module, used to query the device code and its corresponding main isolation code, and transmit the data to the matching module;

[0036] Matching module, based on the relevant data queried, set the time according to the current plan, select automatic matching or match after modifying the corresponding data according to the actual situation;

[0037] The work order update module is used to update the start and completion time of the work order and set the completion time margin of the work order.

[0038] In some embodiments, the nuclear power overhaul work order scheduling control system also includes an interactive module for reminding planning engineers of key areas of concern.

[0039] In some embodiments, the information of the historical overhaul work order includes equipment code, maintenance content, main isolation information, maintenance time, logical relationship of preceding or subsequent work, and abnormalities during maintenance.

[0040] On the other hand, the present invention also provides a computer device, including a memory and a processor, wherein the memory stores computer-readable instructions, and when the processor executes the computer-readable instructions, the steps of the nuclear power overhaul work order scheduling control method are implemented.

[0041] On the other hand, the present invention also provides a computer-readable storage medium, on which computer-readable instructions are stored, and when the computer-readable instructions are executed, the steps of the nuclear power overhaul work order scheduling control method are implemented.

[0042] Compared with the prior art, the nuclear power overhaul work order scheduling control method and system provided by the present invention has the following beneficial effects:

[0043] The present invention analyzes which equipment maintenance work orders have the same main isolation code in combination with a historical database, organizes these work orders, schedules the work orders with the same main isolation code in combination with the main line plan, and during the overhaul implementation process, checks the completion status of the work orders with the same main isolation code, checks the work progress and manages it, thereby greatly improving the work efficiency of planning engineers and avoiding the risk of major human errors such as the main isolation being lifted before the work is completed.

[0044] The present invention can automatically identify and include the master isolation code of a specific device, avoiding errors in the scheduling of planning engineers. After the master isolation code of all work orders is selected, it can be directly queried to track the start and completion of work orders, greatly improving the efficiency of work order management and control, while also reducing the risk of human error.

[0045] The present invention realizes the acquisition and identification of basic elements of a work order system, narrows the range of selection required by planning engineers, and reduces the difficulty of selecting a main isolation code.

[0046] The present invention establishes a keyword maintenance and retrieval mechanism for the main isolation code, so that the work order scheduling management and control platform automatically recommends a suitable code, further narrowing the range of the main isolation code that needs to be selected.

[0047] After the main isolation code is selected, the time can be set and saved directly on the planning software platform without the need for additional data operations, reducing the risk of errors.

[0048] The present invention significantly shortens the planning and scheduling of a single work order from the previous 5 to 10 minutes to 1 to 2 minutes. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In order to more clearly illustrate the technical solution of the present invention, the following briefly introduces the drawings required for the technical description.

[0050] Figure 1 A flowchart of a nuclear power overhaul work order scheduling control method provided by the present invention;

[0051] Figure 2 A structural schematic diagram of a nuclear power overhaul work order scheduling control system provided by the present invention. DETAILED DESCRIPTION

[0052] The following is further explained in detail through specific implementation methods.

[0053] For ease of understanding, we first briefly introduce the existing EAM / eSOMS work order management system. Based on the EAM / eSOMS work order management system, the production unit, unit, specialty, work area, equipment code, overhaul code, work order scheduling group and main isolation code of each work order are obtained. Based on these work elements, the range of selection required in work order scheduling and control selection is greatly narrowed.

[0054] like Figure 1 As shown, the present invention provides a nuclear power overhaul work order scheduling control method, comprising the following steps:

[0055] Step 1: Work order scheduling management. Automatically compare historical maintenance records through set keywords or IDs, query the historical main isolation code, construction period, etc. of the work order, and set the start and completion time of the work order according to the main isolation code window. Step 1 specifically includes:

[0056] Step 1.1: Based on the historical overhaul work order maintenance history database, establish a work order historical maintenance main isolation code database based on the unit, and set keywords inside the work order historical maintenance main isolation code database for easy query.

[0057] Step 1.2: Compare the work order equipment code and work content keywords. If the work order equipment code and work content keywords match the historical maintenance content, proceed to step 1.3; if the work order equipment code and work content keywords do not match the historical maintenance content, proceed to step 1.4.

[0058] In order to assist the work order historical maintenance main isolation code database system to more accurately recommend the main isolation code, the nuclear power overhaul work order scheduling control platform directly displays the read work content and equipment name keywords, and modifies the keywords as new code search conditions according to needs. In this way, planning engineers can find the target main isolation code more efficiently. The main methods are as follows:

[0059] (1) Select the corresponding device code according to the system code, device number, and device type source;

[0060] (2) Select the corresponding equipment code according to the specialty of the work order;

[0061] (3) Identify keywords for equipment names and work contents in the quota manual and recommend equipment codes;

[0062] (4) Identify the equipment code corresponding to the unique item and recommend the code if any;

[0063] (5) For the same equipment code, the verification result may have 1 to 3 different primary isolation codes due to the actual work content. The primary isolation equipment code is automatically matched by comparing the equipment code, specialty, and work content keywords with the historical database work order.

[0064] Step 1.3: Assign the main isolation code of the work order standard. For example, for a valve with the equipment code 1RCV001VP, by comparing the 1RCV001VP equipment code, it can be found that the historical maintenance under this equipment code is all under the main isolation ADT RCV 03, and it can be determined that the maintenance related to 1RCV001VP is all under ADT RCV 03.

[0065] Step 1.4: Assign the standard primary isolation code to the work order based on the primary isolation code given by the historical database. For example, 1RCV001VP in step 1.3 can be assigned the primary isolation code ADT RCV 03.

[0066] Step 1.5: Classify the main isolation codes of the work orders according to their main isolation codes. For example, all work orders under the ADT RCV03 main isolation are put together to facilitate unified time setting and start and completion status statistics.

[0067] Step 1.6: Set the start and completion time and margin of the work order according to the main isolation window. When the time required for some work is less than the main isolation window, you can set a margin. In the event of equipment defects or insufficient human resources, the margin can be used to extend the work order maintenance time, making it easier for planners to determine the bottom line of the work window.

[0068] Step 2: Work order control and management. During the work execution process, for work orders with the same primary isolation code, control operations such as query, analysis, attention, and closure are performed on the work orders according to the primary isolation code. Step 2 specifically includes:

[0069] Step 2.1: Check whether the work order is completed according to the set main isolation code. If the work order status is completed, go to step 2.2; if the work order status is not completed, go to step 2.3. For example, for all work orders under the main isolation code ADT RCV 03, if the planned time has arrived, query the main isolation code ADT RCV 03 to check whether all work orders under the main isolation have been completed. If completed, close the main isolation; if not completed, adjust the completion time and margin.

[0070] Step 2.2: The work order status is completed and the main isolation is closed.

[0071] Step 2.3: Adjust the completion time and margin of the work order, and then check whether the work order is completed. Repeat step 2.1 until all work orders are completed. Planners can pay attention to the completion status of a work order with one click. The nuclear power overhaul work order scheduling control system automatically sends emails / text messages to planners based on the targets they are paying attention to.

[0072] Step 2.4: Notify relevant departments to lift the isolation according to the primary isolation code. Planners can follow the completion of the primary isolation with one click, and the nuclear power overhaul work order scheduling control system will automatically send emails / text messages to notify planners based on the targets they are following.

[0073] In addition, if Figure 2 As shown, the present invention also provides a nuclear power overhaul work order scheduling control system, which summarizes the relevant information of the historical database, sets the work order keywords or ID data, and uses big data to match the main isolation code of the new work order. The planner queries the main isolation code and sets the work order start and completion time according to the main line planning window to improve work efficiency. The nuclear power overhaul work order scheduling control system includes:

[0074] The data module is used to archive and store the equipment codes, maintenance contents, main isolation information, maintenance time, logical relationship of pre- or follow-up work, abnormalities during maintenance, etc. of all previous overhaul work orders. Based on the unit, keywords or ID information can be set inside the work order historical maintenance main isolation code database for easy query, providing retrieval data to the query module.

[0075] The query module is used to quickly query the equipment code and its corresponding main isolation code. The nuclear power overhaul work order scheduling control system can identify keywords based on the equipment code, work content and equipment name, and then retrieve the main isolation code, maintenance period, logical relationship and other key information corresponding to the keyword in the eSMOS historical database, and transfer the relevant data to the matching module according to the needs of the planners.

[0076] In the matching module, planners can choose to match automatically or manually modify the corresponding data according to the actual situation based on the query of relevant data and the current plan setting time. The main isolation code and equipment code are automatically matched. The main method to achieve this function is to narrow the code selection range. For work orders that are triggered by the database, the association can be set by ID, and the matching association is high.

[0077] The interactive module is used to remind planning engineers of key areas of focus. When the overhaul is actually progressing, because a large amount of work is being carried out under the main isolation code in a short period of time, the planning engineer cannot pay attention to the completion of each main isolation in real time. By checking the status of the work order under the main isolation code, it is determined whether the main isolation has been completed. If completed, an email / text message is automatically sent to the login account to remind the planning personnel that the main isolation has been completed; if not completed, a list of unfinished work is exported and sent to each work leader to remind them to complete the maintenance work on schedule. At the same time, for a work order under the main isolation that requires special attention, by setting one-click attention, an email / text message will be automatically sent to the planning personnel after the work is completed, which greatly facilitates the planning personnel to control the work.

[0078] The work order update module is used to update the start and completion time of the work order and set the completion time margin of the work order. When the completion time of the work order is greater than the time window set by the main isolation, the planner is reminded and the data can be updated according to the final confirmation time of the planner.

[0079] The present invention identifies the keywords in the equipment code and work content of the work order, and matches the main isolation code with these keywords during the planning and scheduling, and displays them in the selection interface for the planning engineer to select. At this stage, the planning engineer often only needs to schedule the work order directly according to the equipment maintenance content and the main isolation maintenance window, and the whole process is very fast.

[0080] There is a list of keywords for the main isolation code, which is maintained on the work order scheduling control platform. When the main isolation code cannot cover the work content of the equipment code, the keyword list of the main isolation code can be revised to continuously improve it.

[0081] During the implementation of the work order, by retrieving the main isolation code, the start status, completion status, and unfinished work of the work order under the main isolation code can be queried, and the start and completion time of the unstarted work order can be dynamically adjusted in a timely manner to ensure that all maintenance work under the main isolation code is completed within the specified construction period, and strengthen the planning personnel's control over the work order.

[0082] By using the nuclear power overhaul work order scheduling control system and method provided by the present invention, the efficiency of main isolation code selection is greatly improved, from about 10 minutes per work order to 1 to 2 minutes, and the control of work orders has also reached a real-time level. At the same time, it also improves the work efficiency of planning engineers and reduces the risk of human errors.

[0083] The present invention realizes the acquisition and identification of the basic elements of the work order system, narrows the scope of selection required by the planning engineer, and reduces the difficulty of selecting the main isolation code. By establishing a keyword maintenance and retrieval mechanism for the main isolation code, the nuclear power overhaul work order scheduling control system automatically recommends the appropriate code, further narrowing the scope of the main isolation code that needs to be selected. After the main isolation code is selected, the time is directly set and saved on the system without the need for additional data operation, reducing the risk of errors.
