Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

At present, with the continuous increase in the installed capacity of new energy, the problems faced in the maintenance of new energy station equipment are becoming increasingly prominent, such as: the level of the maintenance team is uneven, the supervision of the maintenance process is difficult to implement, and the maintenance quality is difficult to control. At present, there is no relevant research on a wind power intelligent maintenance system and its method based on multi-dimensional data. Based on solving the problems faced in the maintenance of new energy station equipment, meeting the actual needs of wind and solar station maintenance management, focusing on business functions such as maintenance strategy optimization and maintenance result evaluation, with the help of artificial intelligence technology, it is an urgent problem to carry out the design of intelligent maintenance systems.

To this end, the present application provides a wind power equipment maintenance solution with a reasonable structural design, which can overcome the above-mentioned deficiencies in the prior art and realize intelligent wind power maintenance based on multi-dimensional data.

The embodiment of the present invention discloses a method for maintenance of wind power equipment, which can view the daily maintenance statistics of subordinate companies according to the authority of the company to which the user belongs. Taking the regional side as an example of the specific function, users with regional authority can view the summary maintenance data of all area stations on the map, and at the same time, they can continuously extend the display level through the search conditions above to view the maintenance statistics of the area and its subordinate stations, or they can view the maintenance data of the station, and so on. All summary maintenance statistics within the scope of authority can be viewed in the data dashboard on the system homepage. It is convenient for regional personnel to quickly grasp the current maintenance and operation status of each station equipment and understand the comprehensive maintenance indicators of all stations in real time. As shown in Figure 1, the system includes:

The unplanned maintenance module 11 is used to collect defective tasks of wind power equipment and centrally manage the defective tasks to perform maintenance work.

In the embodiment of the present application, the main function of the unplanned maintenance module is to obtain equipment defects pushed by platforms such as hierarchical diagnosis, remote monitoring, intelligent inspection, and technical supervision, and to manually register equipment defects by on-site personnel, so as to realize standardized, scientific, and intelligent management of a series of processes including defect task collection, intelligent scheduling, work order generation, defect statistical analysis, and transfer of major issues to special maintenance.

The unplanned maintenance module specifically includes:

1. A defect registration unit is used to edit the same defect task of multiple wind power equipment and/or multiple defect tasks of one wind power equipment, and automatically generate a defect registration record according to the edited defect task.

First, the page display part is described. As shown in Figure 2, for defect tasks, all, completed, and pending tasks are for the current user. In the "pending order" task, tasks with a defect level of "class 1" (the most serious level) need to be warned. In addition to the above rules, all tasks are sorted by time. To-do is used to display all pending tasks of the current user, and the arrangement order is the same as above. Completed is used to display all defect tasks that the current user has operated, and the operation bar only has a view details button.

In the embodiment of the present application, the defect registration unit can realize the summary management of the defect tasks of the maintenance module. In daily defect registration, the same defect may occur in the same batch of fan equipment, or multiple defects may be found in one fan. In order to improve the practical applicability of the system, the defect registration unit is provided with the function of multiple selection of defective equipment and grouping of different equipment. Multiple defects can be edited directly at one time in the function interface, and the system automatically splits and processes to generate multiple defect registration records, which is convenient for subsequent statistical analysis of equipment defects.

After the defect task is filled in and submitted, the task will be available on the [All] [To Do] page of all employees with processing authority at the site. When the site manager assigns an employee to handle the task offline, the task will be deleted from the [To Do] page of other employees after the employee performs the next operation.

2. A work order generation and association unit, which is used to merge multiple similar defect tasks in the defect registration record, and generate a defect work order using the merged defect tasks according to the task status corresponding to the defect tasks; and selectively associate the newly generated work order in the defect work order with the generated work order according to the preset matching conditions.

When there are multiple scenarios where the same type of defects need to be handled uniformly, the generated defect information can be merged, and the defects in the waiting-to-be-dispatched state can be associated with the selected work order. Figure 3 is an exemplary schematic diagram of a generated work order. You can select multiple or single information in the list below with a status of "waiting for dispatch". After selecting, click Generate Work Order, and a "Generate Work Order" pop-up window will pop up. You can add or delete the selected information on the pop-up page, and you need to select a work contact on this page. After selecting, click Submit, and the system will generate a defect work order. The newly generated defect work order can be viewed on the "Defect Work Order Page", and the status of the selected list information in the defect task list will be adjusted to "Dispatched".

It should be pointed out that there are five defect statuses for defect tasks: pending submission, pending dispatch, dispatched, completed, and transferred to special maintenance. A status button is provided for each status.

Status to be submitted: view details (basic information, defect registration information), edit, submit;

Status of pending orders: view details (basic information, defect registration information), generate work orders, transfer to special maintenance, and associate work orders; work orders automatically entered by the system are in the status of pending orders by default. Regardless of the entry method, all employees with processing authority at the site can obtain the task from the [All] [To Do] page. When the site manager assigns employees to handle the task offline and the designated employee performs the next step, this task will be deleted from the [To Do] page of other employees.

Order status: View details (basic information, defect registration information, confirmation information, processing information (displayed according to the work order processing status), component replacement record (history record));

Completed status (the corresponding work order has been processed after the order is dispatched): View details (basic information, defect registration information, confirmation information, processing information, component replacement records (historical records and current records), acceptance records);

Transferred to special maintenance: View details.

After clicking Generate Work Order, select the work contact in the pop-up window, and the system will generate a defect work order. The newly generated defect work order can be viewed on the "Defect Work Order Page", and the defect task in the defect task list is updated to "Dispatched". Defect work orders dispatched by the system will be automatically pushed to the "My Work Order" list of the work contact. The work contact can accept the order in "My Work Order" and process the work associated with the defect work order. Only when all the preparatory work before defect elimination is completed can the work be started on site.

When there are multiple similar defects that need to be handled uniformly, the generated defect information can be merged to associate the defects in the pending order status with the selected work order. After clicking Associate Work Order, select a work order from the generated work orders and associate it with the work order. The defect task is updated to "assigned". The matching condition is "work order number" for the work order number, and you can manually enter the fuzzy matching drop-down option. Figure 4 shows a schematic diagram of a page containing defect registration information and associated work orders.

3. A defect task processing unit is used to pre-process, process and accept the defect task based on the defect work order; the pre-processing process includes two-ticket approval association, spare parts association, work instruction association, and maintenance process card association.

The main function of this unit is to pre-process, process and accept equipment defects to achieve defect closed loop.

Among them, the preprocessing process includes the association of two-ticket approval, spare parts, operation instructions, and maintenance process cards.

Two-ticket approval association: In the "Defect Work Order Association Work Page", select to enter the "Two-ticket Approval" interface, click the "Create" button, the system will automatically obtain the draft ticket interface from the two-ticket module system, and perform editing and approval operations on the work ticket. When the maintenance personnel return to the defect work order page after completing the operation in the two-ticket system, the system will automatically generate two-ticket information for the defect work order. Click the "View" button to query the approval progress of the two tickets. After the approval of the associated two tickets is completed, the "Status" column of the "Two-ticket Approval" interface of the defect work order will display completion. Figure 5 shows the generated two-ticket approval page. In the specific implementation process, as shown in Figure 6, click Add, a pop-up window will pop up to select the ticket type; after adding, return to the initial creation page and click View to view the approval progress. Figure 7 shows a schematic diagram of the approval process progress.

Spare parts association: On the "Defect Work Order Association Work Page", select to enter the "Spare Parts" interface, click the "Add" button, the system automatically obtains the material list from the spare parts module system, select the spare parts and click the "Confirm" button, the system sends the application in the spare parts system, and after the approval is completed, the "Status" column of the "Spare Parts" interface of the defect work order will display "Complete". Spare parts are divided into two types: "Spare Parts/Tools". Among them, adding spare parts requires approval, while adding tools does not require approval. Figure 8 shows the generated spare parts page.

Work instruction association: Select from the list of maintenance work instructions in the maintenance knowledge base, click the "Add" button, and the system will associate the selected maintenance work instruction to the defect work order.

Associate maintenance process card: Select from the maintenance process card list in the maintenance knowledge base, click the "Add" button, and the system will associate the selected maintenance process card with the defect work order.

In an embodiment of the present application, the system pushes the defect work order processing task according to the work leader and work shift members set in the two ticket links in the previous link "Associated Work". Task push can choose different notification methods according to the actual business scenario, including: in-site information notification, SMS message notification, and the two push methods support 2-choose-1, and also support all selection. The notification message includes: notification title (defect name), notification type (defect work order), and notification content (defect work order information). After the associated work link is completed, click Submit, and the work order will be pushed to the corresponding work leader and work shift members.

It should be pointed out that if the work leader and work team members of the two tickets in "Related Work" are changed, the processor will also be changed. You need to cancel the processing button at the original work leader, [Work Order Status Changes to Pending Submission], and add a Submit button. Click it to push the message to the new work leader; if only the work team members are changed, add a Submit button to the work leader. Click it to push the message to the corresponding work team members; if both the work leader and the work team members are changed at the same time, add a Submit button to the operation bar of the original work leader. [Work Order Status Changes to Pending Submission], click it to push the message to the new work leader and the work team members at the same time.

After receiving the information, the maintenance/centralized control personnel can log in to the system to receive the to-do work information pushed by the system. The maintenance/centralized control personnel click on the message reminder, and the system automatically queries the defect work order and jumps to the work order processing page to achieve quick operation. The person in charge of the work selects the defect in the "Defect Information" column of the defect work order page and clicks the "Process" button. The "Defect Processing Page" pops up, fills in the "Cause Analysis", "Processing Process", and "Processing Result" on the page, and clicks the "Save" button after confirmation to complete the defect processing operation. It is worth noting that it is necessary to determine that the status of the two tickets and spare parts in the associated work link is in the approval completion status before submitting for processing. Before this, the processing button is grayed out. Clicking the button will prompt in red "Please complete the approval of the two tickets and spare parts first". In other words, there is a restriction that requires judgment that the approval of the two tickets and the approval of the tools and equipment must be completed before clicking "Process".

In addition, the system provides an option to view historical records. In order to help maintenance personnel troubleshoot the causes of defects, the system will automatically display the historical defect registration and processing record inquiries of the defective parts of the equipment. [Work leaders and work shift members] can click to view the detailed information of historical defects, including: defect information, defect confirmation information, defect processing records, and defect acceptance records. In a specific implementation method, the specific process of implementing the page function operation is as follows: In the "Historical Defects" column of the defect work order page, select the historical defect and click the "View" button to pop up the historical defect processing page information, including: serial number, defect type (type), defect confirmation information (level), defect processing information (processing process), defect acceptance information (acceptance result), discoverer, discovery time, and status. In the pop-up historical defect record, you can click "View" to view specific information, including: defect type, acceptance result, defect information (defect location + defect description), defect confirmation information (defect confirmer + defect level), defect processing record (cause analysis + processing process), reference resources (spare parts), etc.

In addition, after the defect is handled, in the "Defect Information" column of the defect work order page, the person in charge of the work selects the defect and clicks the "Maintenance Account" button, and the "Maintenance Account Page" pops up, where the "Maintenance Account" content is filled in. After confirming that the above content is correct, click the "Submit" button to complete the maintenance account operation.

Furthermore, the person in charge of the work confirms whether the acceptance is passed and gives the acceptance opinion (if it is passed, there is no need to fill in the acceptance opinion, if it is not passed, the acceptance opinion is required). The acceptance approval is "passed" or "failed". If it is not passed, you can choose to return [1. Return to the person filling in the report 2. Return to the previous link]. The person in charge of acceptance can upload attachments (attachments are not required). In other words, the restriction condition that two votes are required before the acceptance can be terminated (this is the two-vote logic).

In the embodiment of the present application, the system also provides a suspension (delay) option. The person in charge of the work clicks the suspend button, completes the information filling in the "Suspend Application" page that pops up, clicks Submit, and the person in charge of the department will review and approve it. After the suspension application is submitted, the process is automatically submitted to the person in charge of the department for approval; the person in charge of the department can select the next approver in the approval link. The approval is "passed" or "failed"; if it fails, it is deemed to be rejected for suspension, and it is necessary to return to the normal process for normal processing or re-initiate the suspension application. The person in charge of the work clicks the suspend button to complete the work order activation. The activated work order can choose to transfer to special maintenance or continue processing. As shown in Figure 9, this is a schematic diagram of the processing flow from generating a work order to processing defect tasks, and defect statistical analysis is performed after the acceptance is completed.

4. A statistical analysis unit, used for performing statistical analysis on the wind power equipment according to preset benchmarking options.

In the embodiment of the present application, the statistical analysis unit can query, summarize, count and analyze equipment defects. Defect analysis can solve the classification analysis of faults that occur to the same equipment within a certain period of time, extract, classify, summarize, count and process equipment defect data, and automatically derive the work ticket corresponding to the defect. The same equipment can also be classified and analyzed. Defect statistics can summarize and count the number of defects and the number of defects processed by system, equipment, profession, time period, completion time, defect status, defect category, responsible profession, defect elimination rate, etc., and can also perform defect elimination rate statistics. For completed defect work orders, the timely rate of defect processing can be counted, and statistics can be provided according to the conditions of department, profession, and equipment. As shown in Figure 10, a schematic diagram of the page generated after processing by the statistical analysis unit.

Exemplarily, the benchmarking options may include: failure time, which is the summary time from discovery to processing of all defects in the selected range; number of defects, which is the number of all defects in the selected range; power, which is calculated from the failure time, such as failure time × 016 ÷ 10000 (the specific formula may be determined when the data is accessed); charts, the charts and tables below change according to the filtering conditions above. If an area is selected, the horizontal axis in the chart is changed to the stations in the area, and the statistical type in the table is switched to the stations in the area. If a station is selected, the horizontal axis in the chart is changed to the equipment in the station, and the statistical type in the table is switched to the equipment in the area. If a device is selected, the charts and tables are filtered to display only the chart and table information of the device.

5. A special maintenance management unit is used to pre-set special maintenance conditions, then filter the target defect tasks from the defect registration records according to the special maintenance conditions, and generate a special maintenance plan corresponding to the target defect tasks; review and approve the special maintenance plan, and after the special maintenance plan is approved, split the target defect task into multiple sub-plans.

The main function of this unit is that after the equipment defect is registered and confirmed as a special maintenance, the maintenance personnel edit and modify the maintenance plan to make it meet the current special maintenance conditions. After the maintenance personnel have modified the special maintenance plan, they can submit it for approval. In addition, this unit can also split the maintenance tasks and formulate maintenance sub-plans after the special maintenance plan is approved, set maintenance key nodes, and the split sub-plans can be dispatched independently to generate special maintenance work orders.

If after on-site confirmation, it is considered that this defect belongs to special maintenance, click the "Transfer to Special Maintenance" button, confirm "Whether to transfer to special maintenance" in the pop-up window, select the handler and click Submit, the defect will be transferred to "Special Maintenance Management-Special Maintenance Plan" with the status of "Pending Confirmation". The status of the defect information in the defect task list is adjusted to "Transferred to Special Maintenance". Figure 11 shows a schematic diagram of the page for transferring to special maintenance work orders corresponding to different work order statuses.

In the embodiment of the present application, after the equipment defect registration is confirmed as a special maintenance, it is necessary to obtain the system recommended maintenance plan through the maintenance intelligent decision-making system in the maintenance knowledge base, and generate a special maintenance plan based on the maintenance plan recommended by the system. The maintenance personnel can adjust and modify the maintenance plan recommended by the system to make it meet the current special maintenance conditions. After the maintenance personnel have modified the special maintenance plan, they need to submit it for approval to the district director and relevant leaders of the new energy company. After the maintenance plan is approved, the special maintenance work is carried out according to the plan.

In addition, the change content only allows the addition of maintenance items, and does not allow editing and modification of basic information, and does not allow editing or deletion of added maintenance items. After approval, it is allowed to initiate a "suspended" application.

Figure 21 shows the overall process diagram of the maintenance project plan formulation unit after approval. After the maintenance project plan is confirmed, it is submitted for approval. The approval involves the district director, the new energy livelihood department, and the new energy in-charge leader. The approver can be customized, and the approver's identity is displayed after the approver is selected. If a change application is initiated after the plan is submitted, only the district head is required to approve it. If an extension application is initiated after the plan is approved, the department head (default), livelihood department, and in-charge leader need to approve it. The department head is the default approver, and the livelihood department approver and the in-charge leader approver support customization. After the approver is selected, the identity department information is displayed by default.

2. A maintenance project task formulation unit is used to automatically generate a list of equipment to be maintained according to the maintenance project plan, and formulate regular maintenance project tasks according to the list of equipment to be maintained.

The main function of this unit is to perform regular maintenance work by formulating maintenance tasks. The system automatically generates a list of equipment to be maintained according to the maintenance plan. These equipment to be maintained are stored in the equipment pool to be maintained. When formulating maintenance tasks, it is necessary to obtain the equipment involved in this maintenance task from the equipment pool to be maintained. After the maintenance task is generated, subsequent regular maintenance work orders can be generated. Figure 22 shows an exemplary maintenance project task diagram.

3. A maintenance project work order generation unit is used to preprocess and process the periodic maintenance project tasks so as to generate a periodic maintenance project work order using the processed periodic maintenance project tasks; the preprocessing process includes two-ticket approval association, spare parts association, work instruction association, and maintenance process card association.

The main function of this unit is to pre-process and process equipment maintenance to achieve defect closed loop. Pre-processing includes associating two tickets, spare parts, operation instructions, and maintenance process cards.

The maintenance task specifies the maintenance personnel, maintenance date, and maintenance equipment information, but actual regular maintenance is a very complex task involving many related contents. In order to facilitate maintenance personnel to avoid missing items and standardize regular maintenance work, regular maintenance tasks can be generated into regular maintenance work orders in the system. Figure 23 shows an exemplary maintenance project work order diagram.

In the embodiment of the present application, the system pushes the defect work order processing task according to the work leader and work shift members set in the two ticket links in the previous link "Related Work". Task push can choose different notification methods according to the actual business scenario, including: in-site information notification, SMS message notification. The two push methods support 2-choice 1, and also support all selection. The notification message includes: notification title (defect name), notification type (maintenance project work order), and notification content (defect work order information).

After the associated work link is completed, click Submit, and the work order will be pushed to the corresponding work supervisor and work shift member. At this time, if the work supervisor and work shift member of the two tickets in the "Associated Work" are changed, the processor will also change. It is necessary to cancel the processing button at the original work supervisor, [the work order status changes to pending submission], and add a submit button. Click to push the message to the new work supervisor; if only the work shift member is changed, add a submit button to the work supervisor, click to push the message to the corresponding work shift member; if the work supervisor and work shift member are changed at the same time, add a submit button to the operation bar of the original work supervisor, [the work order status changes to pending submission], click to push the message to the new work supervisor and work shift member at the same time.

Furthermore, click the "Process" button, and the "Maintenance Processing Page" pops up. Fill in the "Cause Analysis", "Processing Process", and "Maintenance Result" on the page. After confirmation, click the "Save" button to complete the defect handling operation. After the defect is handled, in the "Defect Information" column of the defect work order page, the work supervisor selects the defect and clicks the "Maintenance Explanation" button. The "Maintenance Explanation Page" pops up and fills in the "Maintenance Explanation" content on the page. Click the "Acceptance" button, and the acceptance supervisor confirms whether the acceptance is passed and gives the acceptance opinion (if passed, there is no need to fill in the acceptance opinion. If not passed, the acceptance opinion is required). Click Push to choose to push to "Defects" or "Hidden Dangers". If pushed to "Hidden Dangers", the message will be pushed to the platform. If pushed to defects, the information will be pushed to the defect task, and the status is pending confirmation. The associated defect work order column in the maintenance project work order list records the pushed defect task.

4. A second maintenance result evaluation unit is used to compare the indicators of the wind power equipment before and after the maintenance and generate a second evaluation result.

The main function of this unit is to evaluate the effect of this maintenance by comparing the indicators before and after the equipment maintenance. The main evaluation indicators are the equipment energy efficiency index and reliability index in the period before and after the maintenance. The personnel in each area can select the time period according to the company's requirements and check the required energy efficiency index and reliability index to export the evaluation results. Figure 24 shows an exemplary interface diagram of a planned maintenance result evaluation.

The equipment change management module 13 is used to initiate an equipment change application and determine different equipment change degrees according to the equipment change application, so as to perform a corresponding approval process according to the equipment change degree.

The main function of this module is to help the personnel of the area or the centralized control center to initiate equipment change applications and apply for approval according to the company's relevant systems, the management requirements of production equipment changes, and the equipment operation status. Different approval processes are implemented according to the major circumstances of equipment changes. After the approval is passed and the equipment change is completed, the implementation personnel will fill in the equipment change report, which will be approved in turn by the relevant leaders and persons in charge.

The maintenance knowledge base module 14 is used to establish a maintenance knowledge base of a hierarchical structure for the wind power equipment, and train a question-answering model based on the data in the maintenance knowledge base to generate a question-answering robot, so as to use the question-answering robot to provide corresponding fault handling measures for the unplanned maintenance module and the planned maintenance module;

In the embodiment of the present application, the main function of the maintenance knowledge base is to form a knowledge cluster of facts and concepts through comprehensive and organized knowledge management. It is the theoretical basis for equipment maintenance and the basis for intelligent decision-making. Among them, the operating instructions maintain basic information and safety measures, personnel requirements, spare parts and other information to provide guidance for maintenance work. The main function of the maintenance process card is to clarify the processing steps of the maintenance process card when the system performs maintenance operations such as defect elimination and special maintenance. The question-and-answer robot is trained based on existing knowledge to form a question-and-answer model, which can realize intelligent question-and-answer queries on the maintenance plan library, operating instructions, maintenance process cards and other knowledge corresponding to the defects.

The maintenance knowledge base module specifically includes:

1. A defect data dictionary maintenance unit is used to maintain the definition information of the defect task and provide a unified description of the defect task.

In the embodiment of the present application, the system provides a defect data dictionary maintenance unit that can maintain the basic definition information of the defect, which is conducive to the normalization and standardization of basic information by system maintenance personnel. When the basic information needs to be changed, the change to the global application module can take effect immediately. At the same time, creating a defect data dictionary can unify the description of the same defect by business personnel, provide standard words for system users, and improve the professional terminology and daily work efficiency of business personnel. As shown in Figure 25, an exemplary defect data dictionary interface diagram is provided.

In the embodiment of the present application, defect levels are divided for defect tasks in the functional design of the defect data dictionary maintenance unit.

As shown in FIG26, it is a schematic diagram of an exemplary defect level classification for defect tasks. The defect level is used to establish or modify the defect type of the unit. For example, it can be divided into Class I defects, Class II defects, Class III defects, Class IV defects, and can also be divided into emergency defects and general defects, etc. And different processing deadlines can be set for different types of defects. Furthermore, if the defects that may occur in a certain type of equipment are relatively regular, the defect content can be defined. That is, the possible defects are defined in the system, and once the defects are found, the content of the defects can be entered through quick selection. Specifically, the defect level is divided for the defect task, and the corresponding processing deadline is set for the defect task according to the defect level; the corresponding defect content is defined for different types of defects for the defect task, so that the defect content can be matched with the defect task after the defect task is monitored.

It should be pointed out that for the defect data dictionary, the equipment classification and equipment information in defect management should be obtained from the equipment ledger system. Each defect information of the equipment will also be recorded in the equipment ledger system to facilitate comparative analysis of the equipment operation status and equipment quality.

2. A maintenance plan library maintenance unit is used to enter the fault cases of the wind power equipment; wherein the case entry data includes the fault type, fault name, equipment manufacturer, fault phenomenon, number of fault occurrences, fault cause, fault handling plan, fault analysis report, fault phenomenon picture and fault analysis report.

The maintenance plan library records each type of equipment at any time, including: fault type, fault name, equipment manufacturer, fault phenomenon, number of fault occurrences, fault cause, fault handling plan, and fault analysis report. It supports uploading of fault phenomenon pictures and fault analysis reports.

When on-site personnel discover equipment failure, they can quickly search for similar failures in the maintenance solution library based on the equipment manufacturer, failure type, and failure phenomenon. By consulting the failure phenomenon, treatment plan, and failure analysis report of related failure cases and comparing with the actual equipment failure situation, they can quickly identify the cause of the equipment failure and provide a reference solution for solving the actual equipment failure.

There are two ways to enter fault cases into the maintenance plan library. The first is to summarize and refine major equipment failure cases that occur in the industry and enter them into the system regularly. The second is to enter detailed event records, processing procedures, and result analysis into the maintenance plan library after major failures of on-site equipment are handled. The maintenance plan generated in this way needs to be reviewed and approved before it can take effect.

The modules involved in the maintenance solution library include:
