[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0026] As Figure 1 shown in the figure, the present invention proposes a post-maintenance system for nuclear power plant maintenance workers. The system includes a data collection module, a recording module, and a result display module. The data collection module collects work order information and equipment information of maintenance work from an external system, and the data collection module transfers the work order information and equipment information to the recording module; the recording module presets a post-maintenance information unit for maintenance workers, and imports the information collected by the data collection module into the post-maintenance information unit for maintenance workers, and imports the information collected by the data collection module into the post-maintenance information unit for maintenance workers; the result display module displays the progress of the post-maintenance information unit for maintenance workers.

[0027] The data collection module is provided with a software interface, and the software interface establishes a data link with the work order management system and the equipment information management system of the nuclear power plant. The data collection module reads the work order information and equipment information of the work order management system and the equipment information management system. The work order information and equipment information include: work order number, equipment information, staff information, start and completion time, permit, and associated documents, etc. information. Thus, it reduces the burden of personnel record-keeping and at the same time avoids the occurrence of human errors such as incorrect or incomplete records.

[0028] The recording module is used to record the post-maintenance information for maintenance workers, and the recording module is set on the APP software of the intelligent terminal. The recording module has a total of five units. As Figure 2 shown, first, the post-maintenance information unit for maintenance workers includes six subsections: work content, work order number, power plant, unit, person in charge, and planned completion time. The content of the post-maintenance information unit for maintenance workers of the recording module is obtained through the data collection module, and it automatically obtains it from the data collection module through the unique work order number, thereby avoiding the post-maintenance discussion by the staff around the wrong topic.

[0029] As Figure 3As shown, the recording module further includes a work review unit, which consists of 9 subsections, namely: the cleaning of the overhaul site is completed; the equipment nameplates are cleaned without damage; the overhaul tasks reach the expected results; the test equipment and tools are returned; the insulation layer is intact; the construction period is reasonably arranged; whether the anti-foreign object tools and materials (part boxes, blind plates, cloth covers, anti-falling ropes, etc.) are appropriate; whether the control of foreign objects in the environment and equipment (establishing isolation areas, covering openings, plan measures, etc.) is appropriate; whether the cleanliness of the environment and equipment after maintenance meets the operation management requirements. For each of the above subsections, there are two items: inspection results and abnormal situation records. The person in charge can check "Yes", "No", or "NA" (indicating "None") for the inspection results and input the abnormal situation records. By inputting in the software APP, it is avoided that the person in charge writes by hand one by one. By reviewing the above subsections, the completion of work objectives, the use of materials, and the situation of the equipment and the site after repair can be comprehensively reviewed, so as to ensure that the objectives of this work have been achieved, and at the same time, the site is cleared of materials and tools after the work is completed.

[0030] As Figure 4 shown, the recording module further includes an experience feedback unit, which consists of 12 subsections, namely: sufficient staff allocation; sufficient preparation of work documents; personnel skills meet the requirements; the executability of the procedures meets the requirements; there are clear acceptance criteria in the procedures; the risks in the procedures are identified and described; other work documents, such as drawings, work orders, etc. meet the requirements; the replaced old parts need to be refurbished and repaired; unexpected phenomena and alarms occur; defect sheets, quality defect reports (abbreviated as "QDR"), status reports, etc. are submitted; good practices and experience feedback are written; coordination and improvement suggestions are needed, etc. After each of the above subsections, there are also two items: inspection results and abnormal situation records. The person in charge can check "Yes", "No", or "NA" (indicating "None") for the inspection results and input the abnormal situation records, so as to record the main problems and good practices that occur during the implementation of the tasks and feedback on the deficiencies of the documents such as the procedures used in the overhaul.

[0031] As Figure 5 shown, the recording module further includes other work units, which consist of 3 subsections, namely: inspection items, inspection results, and abnormal situation records. Content can be input into these three subsections. By recording other work units, it is convenient for the staff to enter the results of specific items.

[0032] As Figure 6 shown, the recording module further includes a unit for participants. This unit requires the participants to be recorded by face recognition or signature, so as to facilitate the registration of personnel information.

[0033] The result display module is respectively set on the intelligent terminal, the cloud and the web end. The result display module on the intelligent terminal continuously collects the information filled in by each unit of the record module after the maintenance work, and transmits the information to the result display modules on the cloud and the web end.

[0034] The present invention proposes a post-maintenance meeting maintenance system for nuclear power plants. The specific implementation method of the system is as follows:

[0035] The post-maintenance meeting management system for nuclear power plants includes the intelligent terminal on the intelligent terminal, the cloud and the website on the web end. For the intelligent terminal APP, it needs to be installed on smartphones and tablets, and install the post-maintenance meeting management system software for nuclear power plants. Log in with the authorized account, and you can enter the execution end of the intelligent terminal. On the web end, after entering the website address in the browser, you can enter the web interface, log in with the authorized account, and you can enter the web end to browse relevant information.

[0036] After logging in to the software on the intelligent terminal and confirming the return of the work ticket for the nuclear power plant maintenance work, the post-maintenance meeting process for the nuclear power plant maintenance work begins. There are five parts in the post-maintenance meeting.

[0037] First, enter the record module. The first part is the work order information part. The content of the post-maintenance meeting information unit of the record module is obtained through the data collection module. The post-maintenance meeting information unit of the record module automatically displays the following work order information by reading the unique work order number: work content, work order number, power plant, unit, work responsible person / project responsible person, planned completion time. The staff only need to check whether the information is correct and do not need to enter information additionally.

[0038] After confirming that the work order information is correct, the second part, that is, the "work review" link, can be implemented. At this time, the work review unit of the record module displays 9 subsections to the user, which are: 01 The overhaul site has been cleaned up; 02 The equipment nameplate has been cleaned without damage; 03 The overhaul task has reached the expected result; 04 The test equipment and tools have been returned; 05 The thermal insulation layer is intact; 06 The construction period arrangement is reasonable; 07 Whether the foreign object prevention tools and materials (part boxes, blind plates, cloth covers, anti-falling ropes, etc.) are appropriate; 08 Whether the environmental and equipment foreign object control (establishing isolation areas, covering openings, plan measures, etc.) is appropriate; 09 Whether the cleanliness of the environment and equipment after maintenance meets the operation management requirements. There are two columns of inspection results and abnormal situations after each of the above subsections. There are three options of "Yes", "No", and "NA" in the inspection results. The staff make selections according to the actual situation. If "Yes" is selected, the row will turn green, indicating normal, and at the same time, the word "None" will be default displayed in the subsequent abnormal situation column. If "No" or "NA" is selected, the row will automatically turn red, and specific abnormal information must be entered in the subsequent abnormal situation, otherwise the entry operation of the next item cannot be carried out. After completing the information entry of 9 subsections in sequence as required, you can enter the next section.

[0039] The third part is the "Experience Feedback" session. At this time, the experience feedback unit of the recording module shows 12 subsections to the user, which are in sequence: 01 Sufficient staff allocation; 02 Adequate preparation of work documents; 03 Staff skills meet requirements; 04 The executability of the procedures meets requirements; 05 There are clear acceptance criteria in the procedures; 06 Risks in the procedures are identified and described; 07 Other work documents, such as drawings, work orders, etc. meet requirements; 08 The old parts replaced need to be refurbished and repaired for reuse; 09 Unexpected phenomena and alarms occur; 10 Defect sheets, QDRs, status reports, etc. are submitted; 11 Good practices and experience feedback are compiled; 12 Coordination is needed, improvement suggestions, etc. There are two columns for inspection results and abnormal situations after each subsection. Different from the second part, in this section, a selection of "Yes" for the inspection results of the first 7 items indicates normal, while a selection of "Yes" for the inspection results of the last 5 items indicates abnormalities, follow-up work, and good practices, etc. If the inspection results of the last 5 items are selected as "Yes", specific follow-up work order numbers, status report numbers, etc. need to be entered in the subsequent abnormal situation column for continuous tracking. After completing the information entry of the 12 sub-items in sequence according to the instructions, the next session can be entered; otherwise, a pop-up window will display "There are unfinished contents".

[0040] The fourth part is the "Other Work" session. At this time, the other work unit of the recording module shows 3 subsections to the user, which are in sequence: inspection items, inspection results, and abnormal situation records. Staff can enter the results. The system defaults that all three items are "None". For work without a dedicated record form, staff can enter the results in this section. Click on the corresponding positions below the 3 subsections to enter information, and after completion, click the OK button in the pop-up window to save.

[0041] Finally, it is the "Participants" session. At this time, the participants unit of the recording module shows the sign-in interface to the user. The working group members and other members sign in one by one. After each person clicks the signature or MagicPoint scan button, face recognition can be performed through the camera, or signature can be selected to record personnel information. After the sign-in is completed, click End to complete the holding of the post-work meeting. It should be noted that if there are omissions in the entry or the entered content is not standardized, after clicking End of the post-work meeting, the system will pop up a window showing "There are unfinished contents", and all the content must be entered before the post-work meeting can be successfully ended.

[0042] After the post-work meeting starts, the result display module of the software will automatically upload the meeting progress and records to the result display modules on the cloud and the web page.

[0043] After the authorized personnel log in to the web-based nuclear power plant maintenance worker's post-meeting maintenance system, the result display module shows the execution progress and records of the above five links corresponding to each maintenance work to the user. At the same time, the nuclear power plant maintenance worker's post-meeting maintenance system on the web can also view the completed post-meeting records.

[0044] The above embodiments only express several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
