Description

Technical Field

[0001] The present invention relates to the technical field of nuclear power overhaul, and in particular to a method and system for post-nuclear power overhaul test control. Background Art

[0002] Post-repair test refers to the functional identification conducted by multiple parties before the process system is put into use to ensure the reliable operation of the equipment after the equipment maintenance is completed. It is a unique work in nuclear power overhaul. In the refueling overhaul of each unit, the number of work orders for post-repair test is 400-600, accounting for about 10% of all the work orders in the entire overhaul.

[0003] Traditional post-repair testing requires the person in charge of the work to submit a paper application form, which is manually delivered. After the post-repair test manager signs, the application information is entered into an EXCEL spreadsheet. The post-repair test work is then scheduled based on personal experience. The paper results of the on-site test are then submitted to the post-repair test manager by the person in charge of the post-repair test, who then determines whether it is qualified and keeps a paper record.

[0004] This traditional process is very cumbersome. In addition to the test time, the time from application, scheduling, judgment, and input is more than 2 hours. For the person in charge of the work, it takes a lot of time to run errands. For the management personnel, the scheduling accuracy is not high and there are deviations in timeliness. In addition, according to the characteristics of overhaul, post-repair test work also has a peak period. The most typical is that after the low-water level maintenance, a large number of equipment systems need to be tested after repair, resulting in tight time and heavy tasks. If the arrangement is unreasonable, it will lead to delays in the overhaul period and affect the progress of the overhaul. Therefore, efficient post-repair test control is crucial to the safety, quality and progress of nuclear power overhaul. Summary of the invention

[0005] The purpose of the present invention is to provide a nuclear power post-overhaul test management and control method and system to solve the problems of unreasonable test arrangement, untimely test notification or easy omission of participants in the traditional post-overhaul test management process.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] On the one hand, the present invention provides a nuclear power overhaul post-test control method, which receives and determines whether the post-repair test can be carried out. After the post-repair test work order has an accurate planned start time, the post-repair test personnel, start time and location information of the pre-work meeting are notified; the post-repair test management system determines whether the post-repair test is qualified through the submitted post-repair test report data, and if qualified, the record is archived; if unqualified, the post-repair test work is re-executed and the post-repair test report is submitted for judgment.

[0016] Step 8: Determine if the post-repair test is qualified, file the records, and the process ends;

[0017] Step 9: If the post-repair test is determined to be unqualified, return to step 6 and execute step 6 again.

[0018] In some embodiments, if the post-repair test is determined to be a deviation from timely submission of the post-repair test application, the notification module automatically notifies the work leader to submit the post-repair test application as soon as possible; if it is determined to be a deviation from timely scheduling, the notification module automatically notifies the post-repair test manager to complete the scheduling work.

[0019] In some embodiments, step 2 specifically includes:

[0020] Step 2.1: Check whether all other tasks of the post-repair test object equipment are completed through the post-repair test management system. If completed, proceed to step 3; if not completed, proceed to step 4;

[0021] Step 2.2: Check through the post-repair test management system whether all work orders with the same isolation as the post-repair test object equipment have been completed. If completed, proceed to step 3; if not, proceed to step 4.

[0022] In some embodiments, a text message is automatically sent to the person in charge of the work and the cooperating personnel to inform them of the start time of the post-repair test and the location information for holding the pre-work meeting.

[0023] In some embodiments, data information of other maintenance work orders under the target device and information of other work orders with the same isolation as the target device are automatically obtained. Based on the latest completion time of these two types of information work orders, the planned start time of the post-repair test of the target device is automatically filled in.

[0043] The following is further explained in detail through specific implementation methods.

[0044] like Figure 1 As shown, the present invention provides a nuclear power overhaul post-test control method, comprising the following steps:

[0045] Step 1: The equipment undergoes maintenance work. After the maintenance is completed, the post-repair test management system receives a post-repair test request from the person in charge of the work.

[0046] Step 2: The post-repair test management system receives the post-repair test request and determines whether the post-repair test can be performed. The determination method is as follows: Figure 2 As shown, specifically including:

[0047] Step 2.1: Check whether all other work on the equipment is completed through the post-repair test management system. If completed, proceed to step 3; if not, proceed to step 4;

[0048] Step 2.2: Check through the post-repair test management system whether all work orders with the same isolation as the equipment have been completed. If completed, proceed to step 3; if not, proceed to step 4.

[0049] Step 3: Fill in the time for the post-repair test and the location for the pre-job meeting, and go to Step 5.

[0050] Step 4: Accepted, automatically fill in the planned completion time of the latest work order that affects the test as the planned start time of the post-repair test. After all the affected work orders are completed, return to step 2.

[0051] Step 5: After the post-repair test work order has an accurate planned start time, a text message will be automatically sent to the person in charge of the work and the cooperating personnel to inform them of the start time of the post-repair test and the location of the pre-work meeting.

[0052] Step 6: The work supervisor performs the post-repair test work and submits the test report to the post-repair test management system.

[0053] Step 7: The post-repair test management system determines whether the post-repair test is qualified based on the test threshold and historical trend, and the post-repair test manager manually reviews and confirms. If it is confirmed to be qualified, go to step 8, if it is confirmed to be unqualified, go to step 9.

[0054] Step 8: Determine whether the post-repair test is qualified, record and archive, and the process ends. Whether the post-repair test is qualified consists of three aspects: first, the measured data is within the threshold range, second, check the historical trend, there is no continuous deterioration, and finally, according to historical feedback, there are no other problems left. The post-repair test qualification standards include:

[0055] (1) Whether the measured parameters are within the threshold of the device;

[0056] (2) Whether the historical trend of the measurement parameters shows a deteriorating trend;

[0057] (3) Refer to historical experience feedback to determine whether there are any related unresolved issues.

[0058] Step 9: If the post-repair test is determined to be unqualified, return to step 6 and execute step 6 again.

[0059] Step 10: If the post-repair test is determined as a deviation from timely submission of the post-repair test application, the notification module will automatically notify the person in charge of the work to submit the post-repair test application as soon as possible; if the post-repair test management system is determined as a deviation from timely scheduling, the notification module will automatically notify the post-repair test manager to complete the scheduling work as soon as possible.

[0060] As an implementable approach, Figure 2As shown, the present invention provides a method for auxiliary scheduling of post-repair tests, which automatically obtains the isolation condition data information of other maintenance work orders under the target equipment, and then retrieves the planned completion time information of all work orders containing these isolation conditions based on these isolation condition data. The system uses the latest work order planned completion time obtained to fill in the planned start time of the post-repair test of the target equipment.

[0061] like Figure 3 As shown, the present invention provides a nuclear power overhaul post-test management and control system, including a data acquisition module, a data processing module, a notification module and a data storage module.

[0062] The data acquisition module is used to input the equipment maintenance test list. The rule is to automatically obtain the work order data from the EAM (work order system) according to the overhaul code and whether the post-repair test is required to form a total list of post-repair tests. The data acquisition module is also used to input the post-repair test application and automatically obtain the relevant information of the post-repair test application in the EAM (work order system). The data acquisition module is the source of data to be processed by the entire system and is also the interface module with other systems.

[0063] The data processing module is used for post-repair test progress statistics, post-repair test implementation rolling plan, one-time non-qualified rate statistics, statistics on untimely application submission, statistics on untimely scheduling, and statistics on execution according to plan. Its rules are to visualize the post-repair test progress by statistical application or not fields, scheduling fields, implementation fields, and filing fields; automatically calculate the pass rate of the post-repair test by the pass field; judge whether it is not submitted in time by the status of the associated work order corresponding to the application time and the current time; judge whether it is not scheduled in time by the accepted operation time and the application time + 7 days.

[0064] The notification module is used to send information to relevant personnel. After scheduling, the post-repair test management system automatically sends a notification SMS to relevant participants one day before the work is done; when a deviation occurs, the post-repair test management system automatically sends information to the person who caused the deviation to correct the deviation in time.

[0065] The data storage and analysis module is used to store the post-repair test data and form a post-repair test database for the equipment.

[0066] In addition, 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 post-overhaul test control method are implemented.

[0067] 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 post-overhaul test control method are implemented.

[0068] 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.

[0069] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
