Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0046] The first embodiment of the present invention provides a method for analyzing construction cost, such as Figure 1-Figure 3 As shown in Figure 2, the engineering cost analysis method includes:

[0047] S1: Determine the information list specification of the distribution network cost according to the standard design and typical construction content of the distribution network;

[0048] The list specification is a list specification for standardization of equipment and materials, specifically including a distribution network quantity list system established based on standardization of list names, boundaries, attributes, equipment and materials, and hierarchical relationships at each level.

[0049] The specific steps to determine the information list specification for distribution network cost include:

[0050] S101: Obtain element information in distribution network construction projects based on distribution network standard design and typical construction content;

[0051] Distribution network standard design refers to the unified design standards followed in distribution network construction, including standard design requirements for line layout, equipment selection, etc.; typical construction content refers to common and representative construction project contents in distribution network construction, such as common substation construction contents and overhead line construction contents under specific voltage levels.

[0052] Element information refers to the necessary information in distribution network construction projects, which is specifically part of the distribution network standard design and typical construction content.

[0053] S102: Classify and categorize project plans and design module data according to element information;

[0054] S103: Map the results of grading and classification to the lists one by one to establish lists at each level and determine the specifications of the information list for the distribution network cost.

[0055] Establishing standardized inventory specifications for equipment and materials will help improve the accuracy and consistency of the inventory and reduce cost errors caused by non-standard materials.

[0056] By standardizing the list names, boundaries and attributes that correspond one-to-one with the distribution network engineering quantity bill, a list specification is formed, which facilitates project management and cost control.

[0057] S2: Determine the preliminary construction project costs and installation project costs based on the distribution network cost information list specifications and distribution network project investment estimation indicators;

[0058] S201: Determine the investment estimation indicator manual based on the information list specification of the distribution network cost and the investment estimation indicators of the distribution network project;

[0059] An investment estimation indicator manual is compiled based on the price level of the target city and the general design plan, which provides a practical reference for project management personnel and helps to improve the scientificity and rationality of investment decisions.

[0060] S202: Determine the consumption of various materials required for the project based on the investment estimation indicator manual and project scale parameters;

[0061] Project scale parameters refer to the number of substations, capacity, voltage level and overhead line length data under different typical design schemes.

[0062] Determine the consumption of various materials required for the project (such as wires, transformers, etc.), including:

[0063] S2021: Obtain historical data of typical construction contents and process the data;

[0064] Specifically, the historical data of typical construction contents include project scale parameters such as the number of substations, capacity, voltage level and overhead line length under different typical design schemes, as well as the actual consumption of various materials (such as wires, transformers, etc.) corresponding to them. Data processing refers to data cleaning and data standardization. Data cleaning removes erroneous or incomplete data, and data standardization converts data of different units or magnitudes into a unified standard.

[0065] S2022: extracting and selecting features from the historical data after data processing;

[0066] Specifically, for each distribution network project data, relevant features are extracted. For example, the number of substations, capacity, voltage level, overhead line length, and type of typical design schemes are used as input features, and the consumption of various materials is used as the target feature. The feature combination that best reflects the consumption relationship is selected, and some feature selection algorithms such as correlation analysis and principal component analysis are used to reduce unnecessary features and improve algorithm efficiency.

[0067] S2023: Build and train data models based on feature extraction and selected features;

[0068] Specifically, a big data model is constructed based on the extracted and selected features. This model is based on a machine learning algorithm, such as a regression model (linear regression, multivariate regression, nonlinear regression, etc.) or a neural network model (such as a multilayer perceptron, etc.), and the model is trained using the collected historical distribution network project data. For example, if a linear regression model is used, assuming that we have n project scale parameters x1, x2, ..., x n (such as the number of stations, capacity, etc.) and the corresponding material consumption y, the general form of the model is y = β0 + β1x1 + β2x2 + ... + β n x n +ε, where β0, β1, β2,…,β n is the parameter of the model, and ε is the error term. The model parameters are determined by minimizing the error term (such as the least squares method). If it is a neural network model, the weights of the neural network are adjusted by methods such as the back propagation algorithm to minimize the error between the predicted consumption output by the model and the actual consumption.

[0069] S2024: Determine the consumption of various materials required for the project based on the trained data model.

[0070] When a new distribution network project is built, the scale parameters are input and a typical design scheme is selected. These data are input into the trained big data model, and the model calculates the consumption of various materials or resources required for the project based on the input data. For example, in a regression model, the input x1, x2, ..., x n Substitute y=β0+β1x1+β2x2+…+β n x n +ε, the predicted consumption y is obtained.

[0071] S203: Determine the preliminary construction engineering costs and installation engineering costs of the project based on the consumption.

[0072] Specifically, the preliminary construction project costs and installation project costs of the project are determined based on the consumption and project charging rules.

[0073] The project charging rules include pre-regulatory pricing specifications and list pricing specifications. Pre-regulatory pricing specifications are specifications for project cost calculation based on budget quotas. It usually determines the project cost according to the pre-determined quota standards, cost composition and calculation rules. In the calculation process, the applicable budget quota sub-items will be determined according to the type and scale of the project. For example, the corresponding quota unit price is found according to the different construction processes in the distribution network project (such as tower assembly, wire stringing, etc.). Then, the project cost is calculated step by step according to the prescribed cost composition, such as direct costs (including labor, materials, machinery costs, etc.), indirect costs (such as management fees, fees, etc.), profits and taxes. This pricing method emphasizes calculations based on the established quota system. The quota unit price is relatively fixed, and the calculation basis and rates of various costs are also implemented in accordance with regulations;

[0074] The bill of quantities pricing specification is a pricing method based on the bill of quantities. The bill of quantities is a detailed list of the names, characteristics, measurement units and quantities of the sub-items, measures, other items, fees and taxes of the construction project. When calculating the cost, the bill of quantities is first compiled according to the design documents, and then the bidder makes an independent quotation for each list item based on the company's own technology, management level and market price. The quotation includes sub-item costs, measures project costs, other project costs, fees and taxes. Unlike the pre-regulatory pricing specification, the bill of quantities pricing specification pays more attention to the company's independent quotation ability, reflects the market competition mechanism, and has more flexible price formation.

[0075] When building a new distribution network project, the scale parameters are input and a typical design scheme is selected. The consumption is calculated through a big data algorithm, and the construction and installation project costs are automatically calculated based on the project charging rules, which improves the accuracy and efficiency of cost calculations.

[0076] It supports two calculation specifications: pre-regulatory pricing specification and list pricing specification, which meets the needs of different users and improves the versatility and adaptability of the system.

[0077] It supports multiple calculation specifications and data file formats, meets the needs of different users, and improves the versatility and adaptability of the system.

[0078] S204: Determine an analysis report based on the analysis parameters and the preliminary construction engineering costs and installation engineering costs of the project.

[0079] Specifically, the analysis parameters include at least one of basic engineering parameters, material and equipment parameters, region-related parameters, and time-related parameters.

[0080] For example, basic project parameters, such as the voltage level, number of substations, capacity and length of overhead lines, can reflect the scale and basic characteristics of the project and have a direct impact on the project cost; material and equipment parameters, such as the model, specification and brand of the main materials used, etc., different materials and equipment have large price differences, which will affect the project cost; region-related parameters, taking into account differences in labor costs, price levels and policy regulations in different regions, such as regional adjustment coefficients, regional fee standards, etc.; time-related parameters, such as the construction period of the project, material price fluctuations in different periods (which may involve information such as adjustment years), etc., because prices may change significantly over time.

[0081] The analysis report includes at least one of project overview, cost composition analysis, cost index analysis, price analysis, and risk analysis.

[0082] For example, the specific contents of the analysis report include:

[0083] Project overview: including basic information of the project, such as project name, location, scale (such as number of substations, voltage level, etc.), construction unit and design unit, and a brief description of the overall situation of the project;

[0084] Cost composition analysis: List in detail the various cost components of the project, such as the specific composition of the construction project cost and the installation project cost, including the details of the sub-item project cost, the cost of the measures project, the cost of other projects, fees and taxes, etc.;

[0085] Cost index analysis: for example, unit project cost index (such as overhead line cost per kilometer, cost per substation, etc.), by comparing with the cost index of similar projects, analyze the rationality of the project cost;

[0086] Price analysis: analysis of the prices of major materials and equipment, including the source of prices (such as market prices, information prices, etc.), price fluctuations, and rationality compared with other projects;

[0087] Risk analysis: Point out the possible risk factors in the project cost, such as the risk of rising material prices, the risk of policy adjustments, etc., and may give corresponding response suggestions;

[0088] Conclusion and suggestions: Summarize the results of the entire project cost analysis, draw conclusions on the rationality of the project cost, and put forward suggestions for optimizing the project cost, such as whether the selection of certain materials can be adjusted, the improvement of construction technology, etc.

[0089] S3: Determine the project cost based on the material price information, adjustment price information, and the determined preliminary construction project costs and installation project costs;

[0090] Select the latest material price information, automatically obtain similar historical engineering data in the database through artificial intelligence algorithms, recalculate the price, and automatically generate the project cost, which improves the accuracy and efficiency of pricing.

[0091] Specifically, S301: judging the similarity between the historical project information and the material price according to the material price and the historical project information, and determining the similarity between the current project and the historical project in terms of scale;

[0092] The historical project information includes project scale parameters, project type and design scheme type. If these parameters are similar (for example, 80% of the above elements are consistent or close), it means that the projects are similar in scale.

[0093] For example, project scale parameters, such as the number of substations, capacity, voltage level, and length of overhead lines, etc. If these parameters are similar, it means that the projects are similar in scale;

[0094] Project type: if they are all medium and low voltage distribution network projects, they may be the same or similar in terms of power supply area type (urban, rural, etc.) and functional use (such as residential power distribution network, industrial power distribution network, etc.); Design scheme type: adopt similar typical design schemes, such as projects with similar design schemes in terms of tower structure, line layout, etc.

[0095] S302: Determine the project cost based on the similarity in scale between the current project and the historical project, the preliminary construction project cost and installation project cost, and the adjustment price information.

[0096] Different types of projects correspond to different testing standards in the database. One of the testing standards includes voltage level, region type and adjustment year, and the other includes charging standards, material suppliers, adjustment coefficients and quota selection.

[0097] Specifically, the project cost is determined based on pricing specifications, scale parameters, technical and economic parameters, historical projects, design plans and adjustment price information.

[0098] Technical and economic parameters: Technical and economic parameters may include various parameters related to the economic analysis of engineering costs, such as profit margins, tax and fee rates, etc. It may also include some parameters related to cost control and investment benefit analysis, such as internal rate of return, payback period, and other parameters commonly used in economic evaluation. Adjustment price information is a file used to adjust the difference of various costs in engineering costs. It includes the following: material price adjustment, labor cost adjustment, and other cost adjustment. Among them, material price adjustment refers to the adjustment provisions when the material price differs from the budget price or benchmark price due to market fluctuations, etc., and clarifies the adjustment coefficient or adjustment method for different materials; labor cost adjustment refers to the relevant rules for adjusting labor costs according to changes in regional labor costs, policy regulations, etc., such as adjusting according to the labor wage adjustment index in different years and regions; other cost adjustments refer to the content that needs to be adjusted due to changes in policies or market environment, such as machine shift fees and fees.

[0099] This step automatically calculates the project cost by selecting pricing specifications, scale parameters, technical and economic parameters, historical projects, design plans and information prices.

[0100] For example, scale parameters: As mentioned above, in the distribution network project, scale parameters specifically refer to the number of substations, capacity, voltage level, and overhead line length, which reflect the scale of the distribution network project. These parameters have a direct impact on the project cost. Different scale parameters will lead to different material usage and construction difficulty, thus affecting the cost;

[0101] Technical and economic parameters: Technical and economic parameters may include various parameters related to the economic analysis of engineering cost, such as profit margin, tax rate and fee rate. It may also include some parameters related to cost control and investment benefit analysis, such as internal rate of return, investment payback period and other parameters commonly used in economic evaluation. Select the latest material information price file, automatically obtain similar historical engineering data in the database through artificial intelligence algorithm, re-calculate the price, and automatically generate cost data files, which improves the accuracy and efficiency of price combination.

[0102] It provides secondary editing and modification function for cost data files, allowing modification of engineering quantities and material prices, meeting the personalized needs of users and improving the flexibility and operability of the system.

[0103] The calculation in step S2 is a preliminary calculation based on the conditions at the time (such as consumption and engineering fee rules, etc.). The re-pricing calculation in step S3 is based on the latest information such as the material information price file, adjustment file, and similar historical engineering data. This is not a simple repetition of the calculation twice, but a calculation process based on different information; step S2 provides a preliminary reference, and step S3 corrects step S2, and the calculated data in step S3 is usually used as the final engineering cost data. Because the calculation in step S3 takes into account more up-to-date and comprehensive information, such as the latest material prices, adjustment files, etc., it can more accurately reflect the actual situation of the engineering cost.

[0104] S4: Conduct standardized inspections on distribution network engineering projects based on the inspection standards for power grid engineering projects.

[0105] Conduct normative inspection on charging standards, material suppliers, adjustment coefficients and quota selection;

[0106] Conduct normative checks on voltage levels, region types and adjustment years.

[0107] Through the built-in cost document standardization detection rules, the batch-imported distribution network engineering projects can be standardizedly detected, which improves the accuracy and efficiency of engineering detection.

[0108] Different types of projects correspond to different testing standards in the database. The charging standards, material suppliers, adjustment coefficients and quota selection in the project documents are tested, and intelligent prompts are given for non-standard parts, which helps to improve project quality and compliance.

[0109] A second embodiment of the present invention provides a construction cost analysis system, comprising:

[0110] The list specification determination module is used to determine the information list specification of the distribution network cost according to the distribution network standard design and typical construction content;

[0111] The preliminary price module is used to determine the preliminary construction project costs and installation project costs based on the information list specification of the distribution network cost and the distribution network project investment estimation indicators;

[0112] The re-pricing module is used to determine the project cost based on the material price information, the adjustment price information, and the determined preliminary construction project cost and installation project cost;

[0113] The normative detection module is used to perform normative detection on distribution network engineering projects according to the detection standards of power grid engineering projects.

[0114] Furthermore, the inventory specification determination module includes:

[0115] An element information acquisition unit is used to acquire element information in a distribution network construction project according to distribution network standard design and typical construction content;

[0116] A grading and classification unit is used to grade and classify project plans and design module data according to element information;

[0117] The list specification determination unit is used to map the results of grading and classification with the list one by one to establish lists at each level and determine the list specifications for the informationization of distribution network cost.

[0118] Furthermore, the preliminary pricing module includes:

[0119] A manual formulation unit, used to determine an investment estimation index manual according to the distribution network cost informationization list specification and the distribution network project investment estimation index;

[0120] The consumption determination unit is used to obtain the project scale parameters and determine the consumption of various materials required for the project;

[0121] The preliminary cost determination unit is used to determine the preliminary construction engineering costs and installation engineering costs of the project based on the investment estimation indicator manual and consumption.

[0122] Furthermore, the re-pricing module includes:

[0123] A similarity determination unit is used to determine the similarity between the historical project information and the material price based on the material price and the historical project information, and determine the similarity between the current project and the historical project in terms of scale;

[0124] The project cost determination unit is used to determine the project cost based on the similarity in scale between the current project and the historical project and the preliminary construction project costs and installation project costs.

[0125] For example, the intelligent cost level analysis system for distribution network infrastructure projects adopts B / S architecture and establishes a multi-layer application architecture based on the Java EE platform;

[0126] Spring Boot is used as the underlying framework, Mybatis is used as the data persistence layer framework, and MySQL is used as the database, supporting distributed storage and row-level locking;

[0127] The B / S architecture and multi-layer application architecture make it convenient for users to access and operate through a browser, improving the scalability and compatibility of the system.

[0128] Based on technologies such as Java EE platform, Spring Boot framework, Mybatis framework and MySQL database, the stability and reliability of the system are guaranteed. At the same time, it supports distributed storage and row-level locking, which improves data processing efficiency.

[0129] The use of advanced technical architecture and framework ensures the stability and reliability of the system, while supporting distributed storage and row-level locking to improve data processing efficiency.

[0130] It has good scalability and maintainability, is easy to adjust, expand and maintain, and improves the adaptability and sustainability of the system.

[0131] Adhering to the principle of openness, adopting modular design and international standards, the system's compatibility and integrability are improved, making it easier to integrate and exchange data with other systems.

[0132] In this embodiment, the information list specification of the distribution network cost is determined according to the standard design of the distribution network and the typical construction content; the preliminary construction project cost and installation project cost are determined according to the information list specification of the distribution network cost and the investment estimation index of the distribution network project; the project cost is determined according to the material price information, the adjustment price information and the determined preliminary construction project cost and installation project cost; the distribution network project is standardizedly tested according to the inspection standards of the power grid project.
