[0001] The present invention relates to the technical field of nuclear power overhaul, and in particular to a control system and method for a low-water-level preparation phase of nuclear power overhaul. Background Art
[0002] At present, the management and control of low-low water level during the preparation of nuclear power plant overhaul mainly relies on the method of Excel table master list ledger. During the preparation period, the preparation status of low-low water level work orders in the table is tracked through meetings and emails. There are many problems with this method. It takes a lot of work to identify low-low water level work orders; the communication efficiency is low and the progress is slow; due to email communication back and forth, the versions saved by multiple people may be wrong and the information is not synchronized; there is a lack of an overview of the preparation progress, and the overall situation of the preparation cannot be effectively controlled. Summary of the invention
[0003] The purpose of the present invention is to provide a nuclear power overhaul low-low water level preparation phase management and control system and method to solve the problems of low work efficiency of low-low water level work order preparation personnel and lack of process control in the work order preparation phase.
[0004] In order to achieve the above object, the present invention provides the following technical solutions:
[0005] On the one hand, the present invention provides a nuclear power overhaul low water level preparation stage control system, comprising:
[0006] Data acquisition module, used to obtain work order data;
[0007] Data processing module, used to obtain low-water level work orders;
[0008] The process control module is used to calculate the deviation of work order preparation. It compares the current work order status of the work order with the work order status required by the power plant management instructions. If the current work order status lags behind the work order status required by the power plant, it is considered to be a deviation and triggers a reminder.
[0009] In some embodiments, the work order data includes the work order task number, overhaul number, work order status, work order status change time, equipment code, specialty, work supervisor, material status, and primary isolation information.
[0010] In some embodiments, the data processing module includes:
[0011] A low-low-water-level work order acquisition unit is used to acquire low-low-water-level work orders;
[0012] The work order preparation progress visualization unit is used to visualize the status of the statistical low-water-level work orders and display them by category according to the element classification statistics;
[0013] The material preparation progress visualization display unit is used to visualize the status of low-water-level work order materials, and classify and display them according to professional classification statistics (such as machinery, electrical, instrumentation and control, maintenance support, service inspection, anti-corrosion, operation, chemistry, radiation protection, etc.);
[0014] The workload visualization display unit for work supervisors is used to visualize the number of tickets, number of working hours, and average daily number of tickets held by each work supervisor, and is classified and displayed according to professional classification statistics (such as machinery, electrical, instrumentation and control, maintenance support, service inspection, anti-corrosion, operation, chemistry, radiation protection, etc.).
[0015] In some embodiments, the main isolation information of the work order is matched with the main isolation information of the low-low water level. If the main isolation information contains the main isolation of the low-low water level, the work order is determined to be a low-low water level work order. After searching all overhaul work orders one by one, all low-low water level work orders are obtained, and a database storage is established in the nuclear power overhaul low-low water level preparation phase management and control system.
[0016] In some embodiments, the process control module compares the pre-set work order preparation plan with the actual work order preparation progress, screens out work orders that exceed the planned time, and triggers an overdue reminder.
[0017] On the other hand, the present invention also provides a method for controlling the low-water level preparation phase of a nuclear power overhaul, comprising the following steps:
[0018] Step 1: Get the work order data and low-water level isolation number data;
[0019] Step 2: Get the low-water-level list, count the number of work orders according to work order status, material status, and work responsible person, and display them visually;
[0020] Step 3: Calculate the deviation of work order preparation and trigger an alert.
[0021] In some embodiments, step 2 comprises:
[0022] Step 2.1: Compare the low-low water level isolation number customized by the overhaul manager with the isolation number of the work order. If the isolation numbers are consistent, it is confirmed to be a low-low water level work order. If the isolation numbers are inconsistent, it is confirmed not to be a low-low water level work order.
[0023] Step 2.2: Classify the work orders according to multiple dimensional factors such as work order status, material status, and work supervisor, count the total number of work orders in each status under this factor (work order status, material status, work supervisor, etc.), and display the classified statistical data.
[0024] In some embodiments, step 3 includes:
[0025] Import overhaul work order preparation plan;
[0026] Read the work order status and the time when the current status was changed;
[0027] Comparison of work order status and current status change time with preparation plan;
[0028] Determine whether the change time of the current state is greater than the planned time of the corresponding state in the preparation plan. If the change time of the current state is greater than the planned time of the corresponding state in the preparation plan, an overdue reminder is triggered. If the change time of the current state is ≤ the planned time of the corresponding state in the preparation plan, it is judged to be not overdue.
[0029] 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 above-mentioned nuclear power overhaul low-water level preparation phase control method are implemented.
[0030] On the other hand, the present invention also provides a computer-readable storage medium having computer-readable instructions stored thereon, and when the computer-readable instructions are executed, the steps of the above-mentioned nuclear power overhaul low-water level preparation phase control method are implemented.
[0031] Compared with the prior art, the nuclear power overhaul low water level preparation stage control system and method provided by the present invention has the following beneficial effects:
[0032] The present invention has the function of automatically obtaining low-low water level work orders, and can comprehensively display the preparation status of low-low water level projects, especially the deviation reminder of preparation, which greatly improves the work efficiency of low-low water level work order preparation personnel. Overhaul management personnel can also promote the progress of low-low water level preparation according to the overall deviation of low-low water level project preparation.
[0033] The present invention makes the preparation scope of the work order preparer clearer, the communication between the overhaul project manager and the work order preparer more efficient, and the management and control objectives of the overhaul project manager clearer.
[0034] Furthermore, by directly calling the work order isolation number information of the EAM system (the existing work order management system) and comparing it with the customized number of the nuclear power overhaul low-water level preparation phase management and control system, low-water level work orders can be accurately and efficiently identified, saving about 4 hours of work time.
[0035] Furthermore, the low-water-level work order list automatically identified by the present invention has a single source of information for all parties, does not have information bias, reduces email exchanges and meeting communications, and greatly improves work efficiency.
[0036] Furthermore, the present invention statistically displays the progress of work order preparation at a low water level, so that the management and control objectives of the overhaul project manager are clearer, and the deviated professions can be directly found to urge them to prepare as required, thereby achieving the goal of process control.

[0042] The following is further explained in detail through specific implementation methods.
[0043] like Figures 1 to 3 As shown, the present invention provides a nuclear power overhaul low-water level preparation phase management and control system, including a data acquisition module, a data processing module, and a process management and control module.
[0044] The data acquisition module is used to obtain work order data. The work order data includes the work order task number, overhaul number, work order status, work order status change time, equipment code, specialty, work person in charge, material status, and primary isolation information.
[0045] The nuclear power overhaul low-water-level preparation phase management and control system can automatically retrieve all work orders corresponding to the overhaul in the EAM (work order management system) according to the overhaul number, and obtain various field elements of all work orders for the overhaul, including work order task number, overhaul number, work order status, work order status change time, equipment code, specialty, work supervisor, material status, main isolation information, etc., and establish database storage in the nuclear power overhaul low-water-level preparation phase management and control system.
[0046] The data processing module is used to automatically obtain low-water level work orders; it is also used to visualize the progress of work order preparation, the progress of material preparation, and the workload of the work supervisor.
[0047] The specific method of obtaining the low-water level work order is as follows:
[0048] (1) The overhaul manager defines the main isolation information belonging to the low-low water level;
[0049] (2) The main isolation information of the work order is matched with the main isolation information belonging to the low-low water level. If the main isolation information of the work order contains the main isolation of the low-low water level, the work order is determined to be a low-low water level work order. The specific method of visual display is to classify the work orders according to certain factors, and the system uses pie charts, column charts, bar charts and other means to display classified statistical data.
[0050] The data processing module includes a low-water-level work order acquisition unit, a work order preparation progress visualization display unit, a material preparation progress visualization display unit, and a work supervisor's workload visualization display unit.
[0051] The low-low-water-level work order acquisition unit is used to automatically acquire low-low-water-level work orders. The overhaul management personnel define the main isolation information belonging to the low-low-water level. The nuclear power overhaul low-low-water-level preparation stage management and control system automatically matches the main isolation information of the work order according to the main isolation information of the low-low-water level. If the main isolation information of the work order contains the main isolation of the low-low-water level, the work order is determined to belong to the low-low-water-level work order. After searching all overhaul work orders one by one, all low-low-water-level work orders are acquired, and a database storage is established in the nuclear power overhaul low-low-water-level preparation stage management and control system. The low-low-water-level work order acquisition unit can automatically identify the list of low-low-water-level work orders. The information source of all parties is single, there will be no information deviation, and email exchanges and meeting communications are reduced, which greatly improves work efficiency.
[0052] Automatically obtain the low water level work order process Figure 2 Manually enter the low-low water isolation number; compare the isolation number of the work order with the isolation number (custom low-low water isolation number); determine whether the isolation numbers are consistent (whether the custom low-low water isolation number is consistent with the isolation number of the work order). If the custom low-low water isolation number is consistent with the isolation number of the work order, it is confirmed to be a low-low water work order. If the custom low-low water isolation number is inconsistent with the isolation number of the work order, it is confirmed not to be a low-low water work order.
[0053] The work order preparation progress visualization display unit is used to visualize the work order preparation progress. The status of the work order during the preparation period is divided into: preparation, pending approval, approved, and completed preparation. The control goal is to push the work order status to completed preparation. The control system for the low-water-level preparation phase of the nuclear power overhaul counts the status of the low-water-level work order and displays it in the form of a pie chart. You can clearly see the total number of work orders and the number of work orders in each state. You can also classify and count according to factors such as profession, equipment type, and work order type, and display them by category to achieve the function of visualization. The work order preparation progress visualization display unit displays the progress of low-water-level work order preparation, making the control goals of the overhaul project manager clearer, directly finding the deviation of the profession, and urging it to prepare as required, thus achieving the goal of process control.
[0054] The material preparation progress visualization display unit is used to visualize the status of low-water-level work order materials, and is classified and displayed according to professional classification statistics (such as machinery, electrical, instrumentation and control, maintenance support, service inspection, anti-corrosion, operation, chemistry, radiation protection, etc.). Materials are associated with work orders, and each work order will be associated with a number of materials. With the low-water-level work order list, the material list corresponding to the work order can be obtained. The status of materials is: successfully reserved, materials not approved, materials approved but not contracted, contracts signed and in transit, and arrived but not successfully reserved. The nuclear power overhaul low-water-level preparation stage control system counts the status of low-water-level work order materials and displays them in the form of a pie chart. You can clearly see the total number of materials and the number of materials in each state. You can also classify and display them according to professional classification statistics (such as machinery, electrical, instrumentation and control, maintenance support, service inspection, anti-corrosion, operation, chemistry, radiation protection, etc.) to achieve the function of visual display. The material preparation progress visualization unit shows the progress of material preparation for low-water-level work orders, making the management and control objectives of overhaul project managers clearer. They can directly find the executive departments of power plants with material deviations and urge them to prepare according to requirements, thus achieving the goal of process control.
[0055] The visualization display unit of the workload of the work supervisor is used to visualize the number of tickets, working hours, and average daily number of tickets held by each work supervisor, and is classified and displayed according to professional classification statistics. The work supervisor is associated with the work order, and each work order will be associated with a work supervisor. With the list of low-water level work orders, the work supervisor corresponding to the work order can be obtained. The low-water level preparation stage control system of the nuclear power overhaul counts the work supervisor of the low-water level work order, and displays the number of tickets held by each work supervisor (one work order is one ticket), the number of working hours (the number of working hours is the accumulation of working hours for each work order), and the average daily number of tickets held (average daily number of tickets held = number of tickets held / total working days). It is displayed in the form of a pie chart, which can clearly show the total number of tickets held by each work supervisor and the total number of daily average ticket holdings. It can also be classified and displayed according to professional classification statistics (such as machinery, electrical, instrumentation and control, maintenance support, service inspection, anti-corrosion, operation, chemistry, radiation protection, etc.), so as to achieve the function of visualization display. The visualization display unit of the work load of the work supervisor shows the work load of the work supervisor of the work order with low water level, making the control objectives of the overhaul project manager clearer. The work supervisor whose workload does not meet the requirements can be directly found, and he can be urged to change the work supervisor or reduce the workload as required, thus achieving the goal of process control.
[0056] The process control module is used to calculate the deviation of work order preparation. The specific deviation calculation method is: compare the current work order status with the work order status required by the power plant management instruction. If the current work order status lags behind the work order status required by the power plant, it is considered to be a deviation and triggers a reminder.
[0057] The process control module has the function of calculating and reminding the deviation of work order preparation. The power plant has specific progress management requirements for the preparation of work orders during the overhaul preparation period. The preparation of which work orders must be completed at each time node. The control system of the low-water level preparation stage of the nuclear power overhaul can pre-set the work order preparation plan, and then compare it with the actual work order preparation progress, filter out the work orders that exceed the planned time, and trigger the overdue reminder. After receiving the overdue reminder, the power plant management personnel can urge the person in charge to prepare the work order in time to achieve the purpose of process control.
[0058] like Figure 3 As shown in the figure, the implementation process of the work order preparation deviation calculation and reminder function is: import the overhaul work order preparation plan; read the change time of the work order status and the current status; compare the change time of the work order status and the current status with the preparation plan; determine whether the change time of the current status is greater than the planned time of the corresponding status in the preparation plan. If the change time of the current status is greater than the planned time of the corresponding status in the preparation plan, an overdue reminder is triggered. If the change time of the current status is less than or equal to the planned time of the corresponding status in the preparation plan, it is determined to be not overdue and the process ends.
[0059] Based on the existing EAM (work order management system) and E-soms (work order isolation system), the production unit, unit, and main isolation number of each work order are obtained. Based on these work order information, the control system customizes the main isolation number of the low-low water level in the low-low water level preparation phase of the nuclear power overhaul. The control system of the low-low water level preparation phase of the nuclear power overhaul identifies the production unit, unit, and main isolation number of the work order, and determines the work order of the low-low water level by comparing these work order information.
[0060] After obtaining the low-water-level work order, the various elements of the work order can be reorganized and counted to display the work order information that needs to be controlled. This information includes profession, work order status, materials, tools and work supervisors. Professional management can be carried out. The work order preparation progress of each profession can be viewed through the work order status, and compared with the preparation progress required by the power plant to obtain the preparation progress deviation; through the material information, the preparation status of the work order materials of each profession can be viewed, and compared with the material preparation status required by the power plant to obtain the material preparation deviation; through the tool and work supervisor information, the tool preparation status of each profession and the distribution of work supervisors can be obtained. With these deviations, the corresponding profession can be quickly found based on these deviations, and it is urged to advance the work order preparation in accordance with the requirements of the power plant.
[0061] In addition, based on the above system, the present invention also provides a method for controlling the low water level preparation stage of nuclear power overhaul, such as Figure 4 As shown, the following steps are included:
[0062] Step 1: Get the work order data and low-low water isolation number data. These data include the work order task number, overhaul number, work order status, work order status change time, equipment code, specialty, work leader, material status, and main isolation information. All work orders corresponding to the overhaul in the EAM (work order management system) are automatically retrieved according to the overhaul number to obtain the work order data; the low-low water isolation number data is customized and input by the overhaul management personnel according to the actual overhaul situation.
[0063] Step 2: Automatically obtain the low-water list, count the number of work orders according to work order status, material status, and work supervisor, and display them visually.
[0064] The specific steps include:
[0065] Step 2.1: Automatically obtain a list of low-low-water work orders. Manually enter the low-low-water isolation number, and compare the isolation number of the work order with the isolation number. If the isolation number is consistent, it is confirmed to be a low-low-water work order. If the isolation number is inconsistent (whether the low-low-water isolation number is consistent with the isolation number of the work order), it is not a low-low-water work order.
[0066] Step 2.2: Classify the work orders according to multiple dimensions such as work order status, material status, and work supervisor, and count the total number of work orders in each state under each factor (work order status, material status, and work supervisor). The nuclear power overhaul low-water level preparation phase management and control system uses pie charts, column charts, and bar charts to display the classified statistical data.
[0067] For example, the status of a work order is divided into: preparation, pending approval, approved, and completed preparation. When classifying and counting by work order status, you should count how many work orders are prepared, how many are pending approval, how many have been approved, and how many have completed preparation. After obtaining the statistical data, use pie charts, column charts, and bar graphs to display these statistical data.
[0068] Step 3: Calculate the deviation of work order preparation and trigger an alert.
[0069] Import the overhaul work order preparation plan, read the work order status and the change time of the current status; compare the work order status and the change time of the current status with the preparation plan. If the change time of the current status is greater than the corresponding status change time in the preparation plan, the overdue reminder is triggered. If the change time of the current status is less than or equal to the corresponding status change time in the preparation plan, the overdue reminder is not triggered. After receiving the overdue reminder, the overhaul manager urges the person in charge to prepare the work order as required to achieve the purpose of process control.
[0070] In addition, the present invention also provides a computer device, including a memory and a processor, the memory storing computer-readable instructions, and the processor implementing the steps of the above-mentioned nuclear power overhaul low-water level preparation phase control method when executing the computer-readable instructions.
[0071] In addition, the present invention also provides a computer-readable storage medium, on which computer-readable instructions are stored. When the computer-readable instructions are executed, the steps of the above-mentioned nuclear power overhaul low water level preparation phase control method are implemented.
[0072] Computer readable media include permanent and non-permanent, removable and non-removable media that can be implemented by any method or technology to store information. Information can be computer readable instructions, data structures, program modules or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, compact disk read-only memory (CD-ROM), digital versatile disk (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices or any other non-transmission media that can be used to store information that can be accessed by a computing device.
