Description

Technical Field

[0001] The invention belongs to the technical field of calculating profile specifications and models, and specifically relates to a method for calculating the theoretical weight and surface area of ​​a profile, an electronic device and a storage medium. Background Art

[0002] Profiles refer to solid straight bars of metal that have been formed through plastic processing and have a certain cross-sectional shape and size. Profiles come in a variety of varieties and specifications and are widely used in the field of construction engineering. Steel structure engineering quantity calculation is an important part of construction engineering cost control, among which the calculation of the theoretical weight and surface area of ​​profiles is a key step in the calculation of steel structure quantity. In the current calculation method, the calculation of the theoretical weight and surface area of ​​profiles is mainly achieved by consulting traditional paper specifications and calculating in electronic hardware manuals.

[0003] The traditional method of calculating or checking the theoretical weight and surface area of ​​profiles is cumbersome, time-consuming and error-prone, which greatly reduces work efficiency. For the actual needs of steel structure engineering quantity calculation work, this calculation method has room for optimization.

[0004] Although some steel structure quantity calculation software such as the Glodon Steel Structure Quantity Calculation Software has the function of inputting profile specifications and models to generate unit weights, it does not have the function of identifying profile specifications and models. It has great limitations, is not flexible enough, and does not have the ability to simultaneously and quickly process the unit weight calculations of a large number of profile specifications and models.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The object of the present invention is to provide a method for calculating the theoretical weight and surface area of ​​a profile, an electronic device and a storage medium to solve the technical problems raised in the above-mentioned background technology.

[0007] To achieve one of the above purposes, the present invention provides the following technical solutions:

[0008] A method for calculating the theoretical weight and surface area of ​​a profile comprises the following steps:

[0009] S100, establish a standard writing data set covering various profile specifications and models;

[0010] S200, pre-processing the specifications and models of the profiles to be calculated, and removing invalid symbols therein;

[0011] S300, performing full-field matching of the preprocessed specification model of the profile to be calculated with the standard writing data set;

[0012] S400, calculating the theoretical weight and surface area of ​​the profile to be calculated according to the matching result.

[0013] Preferably, in step S100:

[0014] The various profiles include at least hot-rolled steel sections.

[0015] Preferably, in step S200:

[0016] The invalid symbols include at least punctuation marks, numbers, letters, and spaces that are not related to the standard writing data set.

[0017] Preferably, in S400:

[0018] The specific calculation process includes:

[0019] Extract features from various profile specifications and models in the standard writing data set;

[0020] Classify various profiles based on the extracted features;

[0021] According to the matching results, the theoretical weight and surface area formula of the corresponding category of profiles are used for calculation to obtain the theoretical weight and surface area of ​​the profile to be calculated.

[0022] Preferably, the extracted features include cross-sectional type feature characters and specification model feature characters of various profiles.

[0023] Preferably, the specification model characteristic characters at least include specification height, specification width, and specification thickness.

[0024] To achieve the second of the above objectives, the present invention provides the following technical solutions:

[0025] A computer-readable storage medium stores a computer program, wherein when the computer program is running, the device where the computer-readable storage medium is located is controlled to execute the above-mentioned method for calculating the theoretical weight and surface area of ​​a profile.

[0026] To achieve the third objective above, the present invention provides the following technical solutions:

[0027] An electronic device includes one or more processors and a memory, wherein the memory is used to store one or more programs, wherein when the one or more programs are executed by the one or more processors, the one or more processors implement the above-mentioned method of calculating the theoretical weight and surface area of ​​a profile.

[0028] Compared with the prior art, the present invention proposes a method, electronic device and storage medium for calculating the theoretical weight and surface area of ​​profiles, which automatically calculates the theoretical weight and surface area by identifying the writing method of profile specifications and models. Cost estimators only need to input the profile specifications and models to obtain the theoretical weight and surface area of ​​the profiles, which has the following advantages:

[0029] 1. This method can replace consulting paper or electronic specifications, hardware manuals, and complex manual calculation steps.

[0030] 2. The input profile specifications and models are not limited to a specific writing method, which is convenient for calculating the unit weight of the steel section in the table exported by steel structure design software such as TEKLA. It has the ability to simultaneously and quickly process the unit weight calculation of a large number of profile specifications and models.

[0031] 3. This method is in line with the working habits of most cost estimators. It can be formed into independent software or embedded in spreadsheet software such as Excel. The quantity calculation table is easy to maintain in form. Cost estimators can enter information according to their own input habits, which can greatly improve the work efficiency of cost estimators and save labor costs.

[0036] The present application is further described below in conjunction with various embodiments.

[0037] Example 1

[0038] A method for calculating the theoretical weight and surface area of ​​a profile comprises the following steps:

[0039] S100, establish a standard writing data set covering various profile specifications and models;

[0040] S200, pre-processing the specifications and models of the profiles to be calculated, and removing invalid symbols therein;

[0043] Preferably, in step S100:

[0044] The various profiles include at least hot-rolled steel sections.

[0045] Preferably, in step S200:

[0046] The invalid symbols include at least punctuation marks, numbers, letters, and spaces that are not related to the standard writing data set.

[0047] Preferably, in S400:

[0048] The specific calculation process includes:

[0049] Extract features from various profile specifications and models in the standard writing data set;

[0050] Classify various profiles based on the extracted features;

[0051] According to the matching results, the theoretical weight and surface area formula of the corresponding category of profiles are used for calculation to obtain the theoretical weight and surface area of ​​the profile to be calculated.

[0052] Preferably, the extracted features include cross-sectional type feature characters and specification model feature characters of various profiles.

[0053] Preferably, the specification model characteristic characters at least include specification height, specification width, and specification thickness.

[0054] Specifically, currently, the writing of profile specifications is relatively fixed, usually starting with a letter or symbol indicating the profile section type, followed by the specification describing the profile section size, such as HM294*200*8*12. Therefore, a method is proposed to automatically calculate the theoretical weight and surface area by identifying the writing of profile specifications.

[0055] The technical solution of the present invention is as follows:

[0056] 1.

This data set will provide a data basis for subsequent steps.

[0057] 2. Preprocess the data of the profile specification model to be calculated. Preprocessing depends on the application of computer language (including formula language) to eliminate punctuation marks, numbers, letters, spaces, etc. that are irrelevant to data analysis. Unify the writing of profile specifications and models, provide feedback prompts for some doubtful writing, and require the data inputter to modify it. After modification, repeat the data preprocessing.

[0058] 3. Based on the data set established in the first step, perform full field matching on the writing of hot-rolled steel and other national standard profile specifications. This step relies on the application of computer language (including formula language), and its purpose is to find profiles that match a certain specification model, and determine the theoretical weight and surface area of ​​the profile accordingly.

[0059] 4. Automatic calculation of theoretical weight and surface area of ​​welded steel and other non-national standard profiles.

[0060] The feature extraction of the profile specification writing data set is performed through computer language (including formula language), including the profile section type feature characters and specification model feature characters in the profile specification model writing. The specification model feature characters include "specification height", "specification width", "specification thickness" and so on.

[0061] The profiles are classified by computer language (including formula language) according to the characteristic characters of specification and model categories, and the theoretical weight and surface area formula of the profiles of the corresponding categories are calculated using the extracted characteristic characters of specification and model, so as to obtain the corresponding theoretical weight and surface area of ​​the profiles.
