[0040] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that these specific descriptions are only to make it easier and clearer for ordinary technicians in the field to understand the present invention, rather than a restrictive interpretation of the present invention; and as long as there is no conflict, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0041] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments:

[0042] Embodiment 1

[0043] In order to solve the problem that the existing boilers need maintenance personnel to expand the inspection scope of boiler defects and the number of damaged pipe sections to be replaced due to the continuous aging of the units and the coal quality reasons; this embodiment provides a boiler maintenance control method based on a three-dimensional engineering model, wherein the three-dimensional engineering model is a digital expression of the entity and functional characteristics of a facility; various relevant information data are used as the basis of the model to establish a building model, and the real information of the building is simulated through digital information simulation; it has at least one of the characteristics of visualization, coordination, simulation, optimization and plotting.

[0044] like Figure 1 As shown, this embodiment provides a boiler maintenance control method based on a three-dimensional engineering model, and the control method includes:

[0045] S110, drawing a three-dimensional engineering model corresponding to the three-dimensional view of the boiler screen, the three-dimensional engineering model including the attribute information of each maintenance component in the boiler maintenance model, and designing a maintenance database for the boiler required to be maintained at different stages in combination with the three-dimensional engineering model;

[0046] In this embodiment, known three-dimensional drawing software can be used to draw the three-dimensional engineering model corresponding to the three-dimensional drawing of the boiler screen, such as UG, Pro / E, etc., and special three-dimensional drawing software can also be developed according to actual needs; wherein, the three-dimensional engineering model is a three-dimensional drawing composed of various maintenance components used in actual maintenance drawn in combination with the parts and dimensional characteristics of the boiler itself, and according to actual needs, if different maintenance components are required at different maintenance stages, there are corresponding different three-dimensional engineering models. In addition, the three-dimensional engineering model can be combined with the design of a maintenance database for the boiler for maintenance. For example, in the three-dimensional engineering model, the dimensions and / or component usage information that need to be paid attention to during the design and maintenance process of each component are combined, that is, in the process of designing the three-dimensional engineering model, the requirements for the various maintenance components in the boiler maintenance model involved in the boiler maintenance are combined into a maintenance database; the specific form of the maintenance database is not limited in this embodiment, for example, it can be a document, or directly marked in the three-dimensional drawing corresponding to each maintenance component in the three-dimensional engineering model.

[0047] S120, before overhauling the boiler, combining the overhaul database and the attribute information of each overhaul component in the three-dimensional engineering model, simulate and calculate the parameter information of each overhaul component that needs to be prepared;

[0048] For example, based on the current usage status of the boiler, the maintenance database is used to find out which specific maintenance needs to be performed on the boiler, as well as which maintenance parts are needed for these maintenance. The attribute information of each maintenance part in the three-dimensional engineering model is used to simulate and calculate the parameter information of each maintenance part that needs to be prepared.

[0049] For example, Figure 2a Installation of the positioner, or Figure 2b , Figure 2c , Figure 2d Different components in the project, specifically, taking the scaffolding encountered in the plane drawing as an example, can be clearly seen in the three-dimensional model; precise calculations can be made before maintenance to calculate the amount of materials used, the amount of work, and the expected replacement of spare parts; and the maintenance equipment can be analyzed, simulated, and visualized; intervention begins from the design stage of the early stage of the project, timely discovering and avoiding some design errors, and guiding the maintenance work through the three-dimensional visualization model, greatly reducing the problems that arise during the implementation process. Within the scheduled time, when to start construction and when to end; how to construct, how many people, materials, equipment, funds, and time will be used. All can be reasonably arranged and simulated in the computer; ensuring that the maintenance work can be completed on time with quality and quantity guaranteed.

[0050] S130. Send the parameter information of each maintenance component to the terminal where each maintenance operator is located; each terminal where the maintenance operator is located is installed with a specific application that can receive the parameter information of each maintenance component designed and developed in S120, such as the size and material requirements of each maintenance component after conversion into a CAD drawing.

[0051] S140, each maintenance operator confirms whether the processed maintenance parts meet the corresponding required parameter information received in the terminal;

[0052] Each maintenance operator confirms whether the processed maintenance parts meet the requirements, for example, using the recycled water code to correspond one-to-one with the manufacturer's accessories; this improves the quality of accessories, increases maintenance efficiency, and eliminates maintenance quality risks.

[0053] S150. Design a maintenance process for maintenance components according to the three-dimensional engineering model corresponding to the screen stereogram; the component maintenance process may be, for example, the installation sequence or installation precautions that each maintenance operator needs to perform.

[0054] S160. When each maintenance operator confirms that the processed maintenance component meets the requirements of the parameter information, control information is sent to indicate that the processed maintenance component can be maintained according to the maintenance process.

[0055] By adopting the above technical solution provided in this embodiment, the three-dimensional digital model of the component is meshed and can cover all links. The departments where the maintenance operators are located work together, and the work of all maintenance operators is recorded and shared, ensuring the coordination of work from design, construction to materials, making it possible to carry out refined maintenance control based on the three-dimensional platform and reducing waste. Moreover, in the design, construction, operation management and even the entire maintenance life cycle of the boiler maintenance project, all engineering information such as design, processing, maintenance, and project management can be integrated into a unified data model, and any change in any parameter will have a global impact; the maintenance process is analyzed, simulated, visualized, and the construction progress and engineering quantity are controlled in a unified maintenance control.

[0056] In a preferred implementation manner of this embodiment, the parameter information of each maintenance component includes the required material usage, engineering quantity and estimated replacement quantity of spare parts.

[0057] In a preferred implementation manner of this embodiment, the attribute information of each maintenance component includes material, position and number.

[0058] In a preferred implementation manner of this embodiment, the three-dimensional engineering model corresponding to the boiler screen stereogram includes: the design, construction, operation management and maintenance information corresponding to the entire maintenance life cycle of the boiler maintenance project, and the maintenance information can be displayed in the form of a three-dimensional engineering model.

[0059] The traditional idea of ​​boiler maintenance is serial, while the control method based on 3D engineering model is meshed, which can cover all links, and all departments work together. The work of all personnel is recorded and shared, and all engineering information such as design, processing, maintenance, and project management can be integrated into a unified data model. Any change in any parameter will have an overall impact. That is, it provides a platform to ensure the coordination of work from design, construction to materials, making refined management based on 3D platform possible and reducing waste; the relationship between people, between people and technology, and between people and processes has undergone fundamental changes, and the linear way of thinking has been replaced by a divergent way of thinking.

[0060] For example, the control method based on the three-dimensional engineering model can accurately check the position of the heating surface to avoid rework; taking the full furnace scaffolding of the #3 furnace of a thermal power plant as an example, it took only 5 days to set up, freeing up personnel and time for the maintenance of the heating surface. And by carefully calculating the number of racks and racks, the efficiency is improved. Specifically, for example, the cost savings of scaffolding are: saving time: 5 days (saving time) * 15 people * 0.03 million yuan (average salary) = 22,500 yuan; 2. 0.08 million yuan per bend * 24 (overreported bends and bends that were repaired due to errors during each maintenance) = 19,200 yuan; 3. The maintenance is completed early: 2.24 daily power generation profits * 4 days (the number of days saved) = 89,600 yuan. The total maintenance cost savings is 131,300 yuan.
