The terms "first", "second", "third", etc. involved in this application are only used to distinguish similar objects and do not represent a specific ordering of the objects.

[0055] First of all, it should be noted that:

[0056] Cost preparation usually includes five stages: decision-making stage (including project proposal and feasibility study report), design stage (including preliminary design, technical design and construction drawing design), bidding stage, implementation stage (project construction), and completion and delivery stage (completion acceptance).

[0057] 1. Grasp the cost control in the decision-making stage. The key to controlling the project cost lies in the design stage before the project is implemented, that is, after the investment decision and project establishment. This stage outputs the investment estimate cost.

[0058] 2. Focus on controlling the cost in the design stage. Design budget refers to the project cost calculated and determined by compiling engineering budget documents based on the design intent during the preliminary design stage. Compared with the investment estimate cost, the accuracy of the budget cost is improved, but it is controlled by the estimated cost.

[0059] 3. Cost control during the project bidding stage

[0060] On the one hand, bidding can introduce a competitive mechanism for construction projects, allowing construction units to select construction units based on merit; on the other hand, it can reduce project costs and allow the project cost to be output at a more reasonable bidding control price.

[0061] 4. Cost control during the construction phase

[0062] d) Construction drawing budget

[0063] The construction drawing budget refers to the project cost determined by compiling a budget document based on the construction drawings during the construction drawing design phase. It is more detailed and accurate than the estimated cost or revised estimated cost, but it is also affected by the previous stage of the project cost.

[0064] e) Construction budget

[0065] The construction budget is the labor, materials and construction machinery required for the construction of a unit project (or a sub-project) compiled by the construction unit under the control of the construction drawing budget, based on the construction drawings, construction quotas and construction organization design. It is an internal document of the construction enterprise. The construction budget determines the planned cost of the project. It is an internal document of the construction enterprise. The construction budget determines the planned cost of the project.

[0066] 5. Effectively control the project cost during the completion settlement stage

[0067] The final settlement is the last and key step to effectively control the construction cost. The final settlement refers to the final settlement stage of the project, which uses physical quantity and monetary indicators as measurement units to comprehensively reflect the total construction costs of the completed project from the beginning of preparation to the completion and delivery of the project. The final settlement is a document compiled by the construction unit that reflects the actual cost and investment effect of the construction project.

[0068] On the one hand, bidding can introduce a competitive mechanism for construction projects, allowing construction units to select construction units based on merit; on the other hand, it can reduce project costs and bring project costs under more reasonable control.

[0069] The cost data of traditional power engineering projects are scattered and remain on two-dimensional paper, which makes it difficult to intuitively reflect the relationship between cost data and engineering entities. The cost data of each stage are different due to pricing specifications and management requirements. The data comparison between multiple stages lacks depth and dimensions.

[0070] Embodiment 1

For example, in the main transformer system, the smallest unit of the system is the transformer, center point device, lightning arrester, etc. When combining, combine the above smallest units into corresponding cost sub-items (main transformer system). For details, please refer to Figure 3 .

[0076] It can be understood that in the three-dimensional model there are the smallest units of each stage in the cost compilation.

The combined cost results can be displayed in a three-dimensional mode, thereby realizing cost visualization.

[0079] In summary, the cost visualization method based on three-dimensional model in the above-mentioned embodiment of the present invention obtains the sub-item data of each stage in the cost compilation by analyzing the technical and economic documents, and obtains the corresponding sub-item information by parsing the three-dimensional model of the cost compilation, and realizes the visualization output of the cost results by associating the sub-item information with the sub-item data; by combining the three-dimensional model into the dimension of the sub-item of the technical and economic documents, the correspondence between the two is realized, and the effect of cost visualization is achieved. Converting two-dimensional data to three-dimensional solves the problem that it is difficult to intuitively reflect the relationship between cost and engineering entities in two dimensions; at the same time, it can also achieve "precise control, quality improvement and efficiency enhancement" through data-driven, thereby supporting the high-quality development of the power grid.

[0088] S204, combining all the minimum units into corresponding sub-item information according to a preset standard;

[0089] In specific implementation, all the minimum units are combined into cost sub-items to form technical and economic sub-item dimensions. For example, in the main transformer system, the minimum units of the system are transformers, center point devices, lightning arresters, etc. When combined, the above minimum units are combined into corresponding cost sub-items (main transformer system). For details, please refer to Figure 3 .

[0090] It can be understood that in the three-dimensional model there are the smallest units of each stage in the cost compilation. Through the combination of the smallest units, the technical and economic sub-item dimensions are formed to achieve the unification of dimensions and provide a basis for cost visualization.

[0091] S205, respectively parsing the item information and the row data information in the item data corresponding to each stage;

[0092] In specific implementation, by parsing out each sub-item information and the row data information in the sub-item data corresponding to each stage, the correspondence between the row data information components is used to make the three-dimensional model correspond to the technical and economic documents.

[0099] During specific implementation, the corresponding cost information is called in the data model according to the stage information of the cost task, the cost task is processed according to the cost information, and the corresponding cost result is output.

[0100] It can be understood that the cost information contains technical and economic documents corresponding to the information of this stage, and the cost task is processed accordingly by the technical and economic documents, and the output cost result is displayed.

[0101] In summary, the cost visualization method based on three-dimensional model in the above-mentioned embodiment of the present invention obtains the sub-item data of each stage in the cost compilation by analyzing the technical and economic documents, and obtains the corresponding sub-item information by parsing the three-dimensional model of the cost compilation, and realizes the visualization output of the cost results by associating the sub-item information with the sub-item data; by combining the three-dimensional model into the dimension of the sub-item of the technical and economic documents, the correspondence between the two is realized, and the effect of cost visualization is achieved.
