[0033] To make the objectives, technical solutions, and beneficial effects of this application clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention and are used to illustrate the present invention, but are not intended to limit the scope of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] In one embodiment, such as Figure 1 As shown in the figure, this embodiment of the invention provides a method for intelligently generating generator set maintenance plans, including the following steps:

[0035] S11. Establish a maintenance equipment database; the maintenance equipment database adopts a hierarchical structure, including the following levels: power generation group, generator set, system name, equipment name and component name. Each level also includes information content corresponding to each level. The information content includes basic information and maintenance information. The maintenance information includes maintenance time, maintenance ratio, maintenance quantity and defect information.

[0036] The basic information includes commissioning time, material, specifications, and operating parameters; the maintenance information also includes maintenance personnel and maintenance results; the basic information is pre-stored, and the maintenance information is updated based on each maintenance result.

[0037] Because the standards require a large number of devices with varying maintenance ratios, manually creating maintenance items can lead to omissions and errors. This step establishes a maintenance equipment database, which uses a hierarchical database structure, such as... Figure 2 As shown, the first to fifth levels are, in order, power generation group, generator set, system name, equipment name, and component name. Each level contains a sub-node called "Information," and levels with the same name contain identical content. For example, generator sets of the same model have the same system, their systems have the same equipment, and their equipment has the same components. It should be noted that the number of database levels can be increased or decreased as needed. This hierarchical database structure better presents the hierarchical relationships between data related to generator set maintenance projects that meet relevant standards, facilitating querying and management.

[0038] S12. Establish a generator set standard requirement maintenance item table according to the maintenance standards; the generator set standard requirement maintenance item table includes the equipment name or component name required by the standard, as well as the conditions and maintenance plan corresponding to the equipment name or component name; the maintenance plan includes the equipment name or component name to be maintained, maintenance items, maintenance quantity and sampling ratio.

[0039] The establishment of a generator set standard requirement maintenance item table according to the maintenance standard refers to decomposing the maintenance requirements in the maintenance standard into three items: equipment name or component name, conditions, and maintenance plan, and generating the generator set standard requirement maintenance item table. When the same equipment name or component name corresponds to multiple conditions, there is no overlap between the conditions.

[0040] The content of the maintenance plan can include only the component name, maintenance items, maintenance quantity, and sampling ratio as described in the above steps. Alternatively, items can be added, deleted, or modified appropriately according to different situations to meet the maintenance needs. Similarly, the number of items can be adjusted accordingly. In addition, the maintenance results of generator sets put into operation in the same batch have certain similarities, which can be of reference value for generating maintenance plans for equipment that has failed in the same batch.

[0041] S13. Sequentially retrieve the equipment name or component name from the generator set standard requirements maintenance item table in the maintenance equipment database, and match the conditions corresponding to the retrieved equipment name or component name with the information content corresponding to the equipment name or component name in the maintenance equipment database, and generate the maintenance plan corresponding to the equipment name or component name when a match is found.

[0042] The standard maintenance requirements for a generator set in this embodiment are shown in Table 1 below:

[0043] Table 1. Standard Requirements for Maintenance Items of Generator Sets

[0044]

[0045]

[0046] In the generator set standard maintenance item table, even the same equipment or component name will be displayed separately under different conditions. For example, even if the equipment name is "1", the standard requires two conditions (Condition 1 and Condition 2), so the conditions cannot be combined and instead listed as two separate maintenance plans. This setting facilitates better querying and retrieval. Furthermore, the table is automatically generated, eliminating the need for manual review and analysis, thus avoiding errors or omissions due to human factors.

[0047] S14. Based on the maintenance plan, analyze the historical maintenance data to obtain the equipment name or component name number that needs to be maintained.

[0048] The maintenance information for the equipment or component corresponding to the maintenance plan is retrieved from the maintenance equipment database. The numbers of the equipment or component with defect information are compiled into a list. It is determined whether the number of numbers in the list is less than the number of maintenances required by the maintenance plan. If so, the number of the equipment or component with the fewest maintenance times in the maintenance plan is retrieved from the historical maintenance data and added to the list. This process continues until the number of numbers in the maintenance list is not less than the number of maintenances required by the maintenance plan.

[0049] Generally speaking, when equipment quality is roughly the same, the equipment with the fewest maintenance visits is more likely to fail. This invention can not only retrieve equipment with defect information and generate corresponding maintenance plans, but also add the name or component with the fewest maintenance visits to the maintenance list, so that equipment or components that have significant safety hazards but do not yet have defects can be repaired in a timely manner.

[0050] Due to the large amount of historical maintenance data, manually formulating maintenance projects can easily lead to discontinuities with historical maintenance projects, making manual analysis difficult. By combining national standards, the historical maintenance data of this unit, and the historical maintenance data of similar units, we can comprehensively and holistically consider historical data and standard requirements, thus achieving more precise maintenance.

[0051] This invention provides an intelligent generation method for generator set maintenance plans. By establishing a maintenance equipment database for generator sets, the basic information and maintenance information of generator sets can be retrieved. The "historical maintenance data analysis module" is used to analyze the historical maintenance data of this generator set and similar generator sets to obtain the equipment or component numbers with "defects" in historical maintenance, as well as the equipment or component numbers with the fewest historical maintenance times, thereby achieving the purpose of accurate maintenance.

[0052] Based on the above-mentioned intelligent generation method for generator set maintenance plans, this invention also provides an intelligent generation system for generator set maintenance plans, such as... Figure 3 As shown, the system includes:

[0053] Maintenance Equipment Database Module 1 is used to establish a maintenance equipment database.

Each level also includes information content corresponding to each level. The information content includes basic information and maintenance information. The maintenance information includes maintenance time, maintenance ratio, maintenance quantity and defect information.

[0054] Standard analysis module 2 includes: maintenance item table construction module 21 and analysis module 22, such as Figure 4 As shown;

[0055] The maintenance item table construction module 21 is used to establish a generator set standard requirement maintenance item table according to the maintenance standards; the generator set standard requirement maintenance item table includes the equipment name or component name required by the standard, as well as the conditions and maintenance plan corresponding to the equipment name or component name; the maintenance plan includes the equipment name or component name to be maintained, maintenance items, maintenance quantity and sampling ratio.

[0056] The analysis module 22 is used to sequentially retrieve the equipment name or component name from the maintenance equipment database in the generator set standard requirements maintenance item table, match the conditions corresponding to the retrieved equipment name or component name with the information content corresponding to the equipment name or component name in the maintenance equipment database, and generate the maintenance plan corresponding to the equipment name or component name when a match is found.

[0057] The historical maintenance data analysis module 3 is used to analyze historical maintenance data according to the maintenance plan to obtain the number of the equipment name or component name that needs to be maintained.
