Description

Technical Field

[0001] The invention relates to the field of three-dimensional cost technology, and in particular to a method for extending cost attributes based on a pole tower GIM model. Background Art

[0002] With the vigorous development of the BIM industry, its influence has gradually expanded and has touched several industries. The power industry has kept pace with the times and developed its own BIM technology, called GIM. The rise of GIM technology, first of all, has brought about a huge change in the field of construction drawing design. Traditional two-dimensional design drawings no longer meet the requirements. Construction requires more three-dimensional, comprehensive, intuitive and convenient three-dimensional drawings. Therefore, the standardization of GIM models is particularly important, and the first to bear the brunt is the GIM model of the tower. The GIM model of the tower not only needs to meet the design requirements for image accuracy, but also needs to meet the requirements of cost calculation engineering quantity, which requires further improvement of the GIM model on the original basis.

[0003] The pole tower plays an important role in the overhead transmission line project and is the main structure of the entire overhead transmission line. Therefore, the pole tower model must not only meet the accuracy requirements of the design, but also meet the depth requirements of the cost. The current pole tower GIM model can meet the display in the 3D design software, but the attributes are far from meeting the cost requirements. It is necessary to analyze the pole tower GIM model in depth and add relevant attributes to help the cost software meet the requirements of the quota. Summary of the invention

[0004] The purpose of the present invention is to provide a method for extending cost attributes based on a pole tower GIM model, wherein the standardized attributes fully take into account the characteristics of overhead transmission lines, can provide various key parameters of pole towers of overhead transmission lines, reduce the workload of cost estimators, and perform calculations conveniently and quickly, so as to solve the technical problem of insufficient attributes of pole tower GIM models in the prior art.

[0005] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0006] A method for extending cost attributes based on a tower GIM model comprises the following steps:

[0007] Step 100, extracting attribute parameters related to construction cost in the data file of the tower GIM model to obtain construction cost attributes;

[0008] Step 200, obtaining a quota database, extracting the attributes required for applying the relevant quotas of the pole tower, and classifying the attributes to screen out the quota attributes that affect the pole tower GIM model;

[0009] Step 300: Compare the cost attribute with the quota attribute to filter out the attributes to be supplemented that exist in the quota stock but not in the tower GIM model;

[0010] Step 400: Add the attributes to be supplemented to the pole tower GIM model to complete the pole tower attribute expansion.

[0011] As a preferred solution of the present invention, in step 100, obtaining the cost attribute specifically includes:

[0012] Step 101, obtaining data files related to the tower GIM model from the three-dimensional design;

[0013] Step 102: Classify the data files related to the tower GIM model, and filter out the non-technical parameter files related to the tower attributes;

[0014] Step 103, opening the data file related to the filtered tower GIM model, and recording the attributes of the technical parameters of the tower attributes;

[0015] Step 104: classify the attributes obtained in step 103 and extract all cost attributes related to the cost;

[0016] As a preferred solution of the present invention, in step 200, the quota database is the "Electric Power Construction Project Budget Quota (2018 Edition)".

[0017] As a preferred solution of the present invention, in step 300, screening out attributes to be supplemented includes: first using a computer to perform fuzzy matching on cost attributes and quota attributes, and then performing a secondary manual judgment on the matching structure to screen out attributes to be supplemented that exist in the quota library but are not in the tower GIM model.

[0018] As a preferred solution of the present invention, in step 400, adding the attributes to be supplemented to the tower GIM model specifically includes:

[0019] Step 401, determine the attribute storage location;

[0020] Step 402: determine the content and format of data interaction;

[0021] Step 403, determine the data reading form;

[0022] Step 404: Determine the attribute adding method.

[0023] As a preferred solution of the present invention, in step 404, the attribute adding method includes automatic calculation and supplementation and manual selection and addition.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The present invention well supplements the missing parameters of the pole tower GIM model and lays a foundation for the widespread application of the pole tower GIM model. After the parameters of the pole tower GIM model are completed, it is of great help and improvement for the deeper modeling of the three-dimensional design model and the more complete data conversion of the cost software, thereby generating the quota.

[0026] (2) The data supplement of the tower GIM model breaks down the barriers between design and cost, which plays a vital role in the seamless connection between design and cost. According to the supplemented tower GIM model attributes plus the original attributes, the tower-related quotas can be directly applied, which is accurate and complete. This is in line with the concept of the BIM industry and can accurately reflect cost data in real time. This is undoubtedly a huge progress in the application of BIM in the power industry.

Obviously, the drawings in the following description are only exemplary, and for ordinary technicians in this field, other implementation drawings can be derived from the provided drawings without creative work.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1 As shown, the present invention provides a method for extending cost attributes based on the pole tower GIM model. The method normalizes and rationalizes the data through in-depth analysis of the pole tower GIM model and interpretation of the quota, so that the pole tower GIM model data can be extracted to provide stable and effective support for the cost estimation stage. The method specifically includes the following steps:

[0031] Step 100, extracting attribute parameters related to construction cost in the data file of the tower GIM model to obtain construction cost attributes;

[0032] Step 200, obtaining a quota database, extracting the attributes required for applying the relevant quotas of the pole tower, and classifying the attributes to screen out the quota attributes that affect the pole tower GIM model;

[0033] Step 300: Compare the cost attribute with the quota attribute to filter out the attributes to be supplemented that exist in the quota stock but not in the tower GIM model;

[0034] Step 400: Add the attributes to be supplemented to the pole tower GIM model to complete the pole tower attribute expansion.

[0035] In step 100, obtaining the cost attribute specifically includes:

[0036] Step 101, obtaining data files related to the tower GIM model from the three-dimensional design;

[0037] Step 102: Classify the data files related to the pole tower GIM model, and filter out the non-technical parameter files related to the pole tower attributes;

[0038] Step 103, opening the data file related to the filtered tower GIM model, and recording the attributes of the technical parameters of the tower attributes;

[0039] Step 104: classify the attributes obtained in step 103 and extract all cost attributes related to the cost;

[0040] Based on the above, we must first have a comprehensive understanding of the GIM model. The GIM model has a set of national specifications. First of all, we must understand the content of the specifications, that is, we must know the parameters that come with the tower GIM model, and find out the parts that are useful for cost calculation among these parameters. This is a comprehensive analysis process that requires the use of relevant software and analysis with professionals. This method can also use reverse reasoning to compare the assembly properties of the cost software, which is accurate and convenient.

[0041] It is necessary to know the parameters of the tower GIM model and find out the useful parts for cost calculation. This requires computer recognition and analysis. Through programming and software control, data can be extracted from the tower GIM model. In this way, the next step of attribute analysis can be carried out.

[0042] The analysis of the tower GIM model requires the use of special analysis tools, or programming according to the GIM model analysis requirements to read the file and extract parameter data.

[0043] In step 200, the latest quota database refers to the "Electric Power Construction Project Budget Quota (2018 Edition)", analyzes and reorganizes the tower-related quotas, extracts the attributes required for the quotas, and then sorts and compares the attributes, divides the attribute types, and determines whether the attributes can be put into the model, how users in the model input data, and whether the name of the attribute can be accepted by most people.

[0044] In step 300, filtering out the attributes to be supplemented includes: firstly using a computer to perform fuzzy matching on the cost attributes and the quota attributes, and then performing a secondary manual judgment on the matching structure to filter out the attributes to be supplemented that exist in the quota library but not in the tower GIM model.

[0045] After the tower GIM model data is determined, the data interaction form needs to be determined. First, determine where to store the data. The GIM model file is not just one, there are many subsidiary files associated with the model. After determining the attribute storage location, it is also necessary to determine the content and format of the data interaction so that the data is not read incorrectly during data transmission. The importance of specifying the format is crucial for data interaction. Therefore, the format is a key point, but it is not a difficult point. It only needs to be standardized. The next step is the data reading form, which is related to the corresponding interface. Specific problems require specific analysis. The existing market data interfaces can generally meet the requirements.

[0046] After the cost attributes of the tower GIM model are supplemented, it is necessary to comprehensively analyze the attribute adding method, which is mainly divided into automatic calculation supplement and manual selection addition. Such a flexible combination can ensure the integrity of the data to the greatest extent, thereby achieving the supplement of the tower GIM model data at night. Table 1 lists some extraction examples of tower GIM model parameters and extended tower cost model parameters.

[0050] The improvement of the cost attributes of the pole tower GIM model is of great help to design, cost and construction. With the development of BIM today, the requirements for three-dimensional design and construction are increasing and the requirements are increasing. This method of expanding the cost attributes based on the pole tower GIM model has broken through professional barriers and can be applied to all professions, greatly improving the efficiency of cost. The data is complete enough and only some quotas need to be adjusted to generate the cost.
