[0121] Step C7: Start and register the microservice; Start the newly created microservice and ensure that it can be successfully registered with the service registration center. For example, the appearance of ruoyi-test in Nacos indicates that the service registration is successful.

[0122] Step C8: Create menu items; create corresponding menu items according to the functions of the newly created microservice to ensure that the front-end can access the functions provided by the microservice; if a code generator is used in the process, the code generator needs to be used to generate the front-end and back-end codes corresponding to the microservice;

[0123] Step C9: Perform relevant configuration of the database; the relevant configuration of the database includes information such as data source configuration and database connection to ensure that the database configuration of the new service is correct;

[0124] Step C10: Manage the dependencies of the microservice through build tools such as Maven or Gradle to ensure that the required libraries, process cost management module, data report specification management function module, automatic construction settlement function module and automatic completion settlement function module can be correctly introduced.

[0125] The automatic construction settlement function is to combine the difference data between the construction drawing budget and the bidding quotation based on the structured data of the construction unit's bidding quotation to form the benchmark quantity for construction fee settlement. It includes the following steps:

[0126] Step D1: Establish the reporting, review and approval process for process settlement; during the construction process, the construction unit can apply for settlement of completed project quantities at any time, and after approval, it will serve as the basis for applying for progress payment;

[0127] Step D2: After the construction is completed, the system automatically summarizes all the settlement quantities of the construction process, and the design changes, on-site visas and construction contract assessment data of the existing technical and economic perception micro-applications; by associating the construction process settlement with the progress payment, the payment of the construction unit is controlled in real time.

[0128] Step D3: Automatically generate a construction settlement report through the built-in power transmission and transformation project list pricing specification report template to achieve one-click settlement of construction costs.

[0129] Automatic final settlement includes the following steps:

[0130] Step E1: Configure the settlement approval form and full-caliber settlement report template that meet the requirements for the preparation of the State Grid's power transmission and transformation project settlement report;

[0131] Step E2: After the completion of the project, after unit conversion, data collection, data classification and cost sharing principles, the main project characteristics, construction costs, party-supplied material costs and other cost settlement data are automatically summarized, and a project overview table, a project completion settlement summary table, a building installation project construction cost settlement list, a list of other costs, a summary table of major equipment and materials, and a power transmission and transformation project settlement approval table are generated, thereby replacing the offline manual preparation of settlement approval tables and full-caliber settlement reports, realizing project completion settlement, and effectively reducing the settlement time of the project after completion.

[0132] The settlement process of the electronic settlement platform for power transmission and transformation projects includes:

[0133] Step 1: Based on the comprehensive digital management platform for the entire infrastructure process, the construction unit will settle and upload all construction costs through the automatic construction settlement function; the construction cost mainly realizes the online circulation and approval of the process settlement and completion settlement application of the construction cost. The construction cost includes the construction and installation engineering cost, other construction costs and adjustable construction costs. The process settlement automatically generates the process construction settlement report according to the selected settlement costs, and the completion settlement automatically generates the completion settlement book according to the requirements of the State Grid Engineering Quantity List Pricing Specifications based on the construction costs that have been submitted for review. After the construction project department fills in the construction settlement costs, it will be pushed to the supervision project department, the owner's project department, and the construction management unit for approval in turn, realizing the online circulation of construction cost settlement. After the construction settlement costs are approved, the settlement amount is immediately pushed to the progress payment application module for the construction unit to apply for the progress payment of the project; the progress payment conditions are set. After completing the process settlement approval, the progress payment of this stage can be applied, which promotes the timely confirmation of the completed project volume, standardizes the timely collection of process acceptance materials, and realizes the management goal of clearing the completed volume and price.

[0134] like Figure 2As shown in the approval flow chart of process construction settlement in an electronic settlement platform for power transmission and transformation projects, the process construction settlement uses intelligent algorithm models to achieve efficient management. The construction project department combines the on-site simulation image progress and carries out process settlement of completed engineering quantities at any time in accordance with the measurement cycle requirements that do not exceed the construction contract. The completed equipment supplied by the second party, design changes and on-site visas, as well as the issued construction assessment forms are settled in real time. The advanced intelligent core engineering settlement model is used to automatically generate process construction settlement reports. The reports are submitted to the supervision project department, the owner's project department and the construction management unit for approval, and the approval opinions are filled in to realize the online operation of process construction settlement. According to the settlement plan, the settlement of construction costs is process-oriented, and the relevant construction cost settlement materials are circulated online to improve the timeliness of construction cost settlement. Through intelligent algorithm models, the online circulation and approval of the process construction settlement and final settlement applications of construction costs are realized, and the advanced Zhihe Engineering Settlement Model is used, combined with the cost cleaning algorithm, to automatically generate the process construction settlement report and the final settlement statement; after the construction project department fills in the construction costs, with the help of online process engine technology, it is pushed to the supervision project department, the owner's project department and the construction management unit for approval in turn, realizing the full process of construction cost settlement online operation; once the construction costs are approved, the settlement amount will be immediately pushed to the progress payment application module, for the construction unit to apply for the corresponding progress payment of the project.

[0135] like Figure 3 As shown in the approval flow chart of bidding agency service fees in an electronic settlement platform for power transmission and transformation projects, the settlement of construction bidding agency service fees, i.e. the bidding fees, is managed efficiently through an intelligent algorithm model. After the construction bidding of the project is completed, the bidding agency service fees are clearly invoiced, and the construction unit can automatically apply for bidding fee settlement and connect to business data in real time; the system will fill in the settlement amount and upload the cost voucher, and submit it to the supervision project department, the owner's project department and the construction management unit for approval in turn, and fill in the approval opinions; after approval, the hierarchical clustering algorithm is used, and the settlement amount will be automatically included in the construction cost settlement, realizing the online operation of construction cost settlement.

[0136] like Figure 4As shown in the approval flow chart of construction site fee settlement in an electronic settlement platform for power transmission and transformation projects, the settlement of construction site fees includes a fixed total price and a provisional amount, that is, during the construction process, when land expropriation, house demolition and other construction site requisition and clearance costs occur, if the costs are borne by the construction unit, the construction unit will digitize the actual settlement amount and related cost vouchers and upload them to the system; use deep learning algorithms to intelligently review the submitted materials, and automatically route the review process to the supervision project department, the owner's project department and the construction management unit; each relevant department fills in the electronic approval opinion through the intelligent approval interface. Once the approval is confirmed, the system automatically integrates the approved settlement amount into the total construction cost to ensure that the entire stage process is efficient, transparent and traceable.

[0137] like Figure 5 As shown in the approval flow chart of other construction fees in an electronic settlement platform for power transmission and transformation projects, the settlement of other construction fees is for the construction unit to fill in other provisional amounts and provisionally estimated cost items in the bidding documents that actually occurred, including the settlement amount and voucher of the site construction fee. AI technology is used to automatically extract verification information and generate an approval process, and then it is electronically approved by the supervision project department, the owner's project department and the construction management unit in turn, which intelligently ensures that the data is accurate and compliant. The final approved fees are automatically included in the total construction fee settlement, which significantly improves settlement efficiency and transparency.

[0138] like Figure 6 As shown in the approval flow chart of personnel, material and equipment adjustment in an electronic settlement platform for power transmission and transformation projects, the personnel, material and equipment adjustment is dynamically managed through intelligent algorithms. After the completion of the project, the construction unit applies for price adjustment based on the contract, and the AI ​​review automatically compares the market changes and evaluates the rationality. After the review is passed, an approval process is generated and submitted to the supervision project department, the owner's project department and the construction management unit for electronic approval in turn, which intelligently ensures that the data is accurate and compliant. The final approved costs will be automatically included in the construction cost settlement, realizing efficient and accurate management.

[0139] like Figure 7 As shown in the construction cost adjustment approval flow chart in an electronic settlement platform for power transmission and transformation projects, the construction cost is adjusted after the completion of the project. If part of the project volume has not been constructed and there is no change visa, the construction project department or the owner's project department needs to upload the cost calculation sheet of the reduced part, and use the deep learning algorithm to automatically review and adjust the contractor's supply of equipment and supply of materials unloading storage fees and taxes. After the construction management unit uses AI analysis and approval, the adjustment is automatically included in the construction cost settlement to ensure the accuracy of the data and improve the efficiency and transparency of the settlement process.

[0140] Step 2: Each construction unit will settle and upload the other expenses incurred by each of them. The other fee settlement part uses the intelligent algorithm model to realize the online entry and declaration of other fees specified in the preliminary regulations. The data of other fees are applied by the design project department, supervision project department, owner project department and other parties in turn, or automatically synchronized from the full-caliber budget and ERP system, and then reviewed or confirmed by the technical and economic specialists of the construction management unit using AI technology. Other fees that pass the review will be automatically included in the completion stage. Through the automatic docking or batch import of the system, the workload of manual repeated entry is reduced; and the cost division is clear, the supporting materials are complete and standardized, and the settlement data is accurate and traceable.

[0141] The owner's voluntary compensation for site construction fees is the cost of requisitioning and clearing the construction site, such as land expropriation, which is automatically compensated by the owner during the construction process. After the cost occurs, the owner's project department needs to upload the cost voucher and other content to the system in a digital way, and use AI technology to automatically review and generate the approval process. After approval by the technical and economic specialists of the construction management unit, the fee will be automatically included in the settlement of other fees to ensure the accuracy and compliance of the settlement process.

[0142] After the review of the settlement documents of the construction drawings is completed, the approved version of the full-caliber budget is uploaded to the e-Infrastructure 2.0 platform, and the contract amount of each fee is automatically extracted using a deep learning algorithm, and the settlement adjustment coefficient is determined in combination with big data analysis; the project assessment fees of each unit are collected, and the settlement fees are automatically calculated using AI technology. The design project department, the owner project department, and the supervision project department confirm the fees for the survey and design fees and their bidding fees, the construction process cost consulting and project settlement review fees and their bidding fees, and the project supervision fees are respectively confirmed by the design project department, the owner project department, and the supervision project department, and the contract or other voucher attachments are uploaded. The system will automatically submit them to the construction management unit for electronic approval, and the fees will be included in the settlement of other fees after approval. .

[0143] The preliminary work fee is automatically extracted from the full-caliber budget file of the e-Infrastructure 2.0 platform using an intelligent algorithm, which does not include the detailed expenses of the preliminary work management fee. At the same time, the preliminary work management fee is synchronized or imported through the ERP system. The owner's project department is responsible for confirming and uploading the contract and other attachments. The system then automatically submits it to the construction management unit for electronic approval. After approval, the fee will be automatically included in the settlement of other fees.

[0144] Project legal person management fees, equipment and material supervision fees, engineering insurance premiums, intellectual property transfer and research and testing fees, post-project evaluation fees, engineering construction testing fees, power engineering technical and economic standards compilation fees, production preparation fees, large-scale transportation measures fees, professional blasting service fees and construction period loan interest are synchronized from the ERP system or manually imported. The system uses intelligent algorithms to automatically link the fees to the corresponding individual projects and expense items according to the WBS code; at the same time, the system automatically calculates the service fees as the settlement amount; the construction management unit is responsible for confirming the fees, uploading contracts, expense vouchers or other supporting materials, and completing the entire approval process.

[0145] Step 3: If Figure 8 As shown in the approval flow chart of the materials supplied by Party A in the electronic settlement platform of a power transmission and transformation project, the settlement part of the materials supplied by Party A mainly realizes the automated management of the settlement application process of the materials supplied by Party A after completion through the intelligent algorithm model. After the owner's project manager completes the process of returning and benefiting the materials supplied by Party A, the system automatically obtains the settlement data of the materials supplied by Party A from the materials ERP or the data imported in batches from Excel. Then the owner's project manager initiates the settlement application for the materials supplied by Party A. The system uses AI technology to automatically connect to the level of the budget project according to the WBS code in the ERP, and submits it to the construction management unit for review. After the review is passed, the system will automatically complete the settlement process. The settlement of the materials supplied by Party A obtains the quantity and amount of the outbound delivery by importing the ERP material procurement status table, which promotes the timeliness of the procedures for the outbound delivery, return and balance benefit of materials. At the same time, the full-caliber construction drawing engineering quantity review and the review of the materials supplied by Party A are carried out simultaneously to further standardize the material management.

[0146] Step 4: Fig. 9 As shown in the completion settlement approval flow chart of an electronic settlement platform for power transmission and transformation projects, the completion settlement part mainly uses advanced intelligent algorithm models to realize the automatic collection and aggregation of construction costs, other costs, and approved costs of materials supplied by Party A after completion;

[0147] The system automatically generates full-caliber settlement reports for single dimensions and settlement approval forms for transmission and transformation projects. The technical and economic specialists of the construction management unit are responsible for submitting the reports, which are then approved in turn by the director of the construction department of the construction management unit, the manager in charge, the technical and economic specialist of the Provincial Economic Research Institute, the technical and economic department of the Provincial Construction Department, and the director in charge of the Provincial Construction Department. The system supports filling in approval opinions and electronic signatures during the approval process. After approval, the full-caliber settlement reports and settlement approval forms will be automatically pushed to the e-Infrastructure 2.0 platform for archiving and storage, realizing the intelligence and efficiency of the settlement process.

[0148] Table 1 is the data flow of each settlement data, and Table 1 is as follows:

[0149]

[0150] Table 1

[0151] Step 5: The platform can query the settlement execution and settlement completion of statistical projects through dimensions such as construction management units, settlement time, and voltage level; approve the full-caliber settlement report, and conduct engineering quantity review after the full-caliber construction drawing review is completed, further deepen and improve the construction drawings, form the quantity difference between the construction drawings and the bidding quotation, perform quantity difference change approval, clarify the planned construction quantity, and eliminate the drawbacks of arbitrarily changing drawings and not constructing according to the drawings during the construction process; at the same time, statistical analysis can be performed on the engineering quantity and comprehensive unit price. It is convenient for provincial companies and construction management units to control the settlement progress and quality of the project. Change visas, construction costs, and process settlement approvals are all circulated online, eliminating the drawbacks of offline approval appointments and waiting for people, ensuring that various approvals are timely and efficient. It improves the timeliness of approval work, shortens the time difference of funds, and stimulates the enthusiasm of construction units to invest in human, financial, and material resources. And there is no need to prepare full-caliber settlement reports offline. The automation of settlement preparation is realized.
