Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the calculation of the engineering quantity is realized by using the computation software, and because the expression of the component type and the component material attribute in the computation software is different from that in the modeling software, the BIM model built by using the modeling software is not compatible when being directly applied to the computation software. To solve this problem, it is common in the prior art to perform modeling anew in the computation software, or to modify the BIM model again after the BIM model is introduced into the computation software, or the like. However, these approaches result in inefficient engineering calculations due to the re-building of the model involved.
Based on this, the embodiment of the invention provides a component matching method, after a building model is imported into computational software, electronic equipment automatically performs matching conversion on the attributes of components to be matched of target primitives in the building model, so as to obtain the attributes of the target components which can be directly used for engineering quantity calculation. For example, if a window is represented as a in the BIM model and B in the computation software, which can be used directly for the engineering computation, then a match needs to be converted to B. Among them, details about a specific member matching method will be described below.
In accordance with an embodiment of the present invention, there is provided a component matching method embodiment, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
In this embodiment, a component matching method is provided, which can be used in the above-mentioned electronic devices, such as a computer, a mobile phone, a tablet computer, etc., fig. 1 is a flowchart of the component matching method according to the embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:
and S11, acquiring the target building model.
The target building model is a building model for calculating the engineering quantity, and the target building model can be stored in the electronic equipment in advance or can be imported into the electronic equipment in real time when needed. The target building model may be a format file such as RVT or IFC. For example, the electronic device provides a file import interface for providing a user with the option to upload a target building model for which computation calculations are desired.
And S12, analyzing the target building model to obtain the attributes of the members to be matched of the target primitives.
The electronic equipment analyzes the target building model after acquiring the target building model, determines each primitive in the target building model by a method of identifying keywords of the target building model, and extracts the component attribute of each primitive to obtain the component attribute to be matched of each primitive.
The electronic device may perform matching conversion on component attributes of a certain primitive, or perform matching conversion on component attributes of some primitives, and the like, and may specifically perform corresponding setting according to actual situations. In this embodiment, the primitive that needs to perform matching transformation on the component attributes is referred to as a target primitive.
Specifically, the electronic device analyzes the target building model to obtain the attributes of the members to be matched of the target primitives in the target building model. The component property to be matched may be a component type, a component material property, a component name, or the like, and the component material property is used to indicate a material corresponding to the component type. For example, the target primitive 1 has component types a1, a2, A3 and a4, and the component material attributes corresponding to the component types B1, B2, B3 and B4; the target primitive 2 has component types A5 and A6, and the component material attributes for each component type B5 and B6, and so on.
Optionally, in order to ensure the efficiency of component matching, the electronic device may further parse the floor information of the target building model to perform batch processing of the target primitives on the same floor. Further optionally, to ensure calculation of subsequent engineering quantities, the electronic device may further analyze the floor height and floor elevation information of each floor.
And S13, inputting the attributes of the component to be matched into a preset matching model, and determining the attributes of the target component corresponding to the attributes of the component to be matched.
Wherein the target component attribute is attribute information directly used for engineering quantity calculation of the target building model.
After obtaining the attributes of the to-be-matched members of the target primitive in S12, the electronic device may directly input the attributes of the to-be-matched members into the preset matching model, and determine the attributes of the target members corresponding to the attributes of the to-be-matched members. Specifically, the input of the preset matching model is the attribute of the component to be matched, and the output is the matched attribute of the target component. That is, the input may be the component type and component material attributes of the target primitive, e.g., name, material (wall, beam, panel, column, door, window), and the output is the representation of the component type and component material attributes in the computation software. The specific model structure of the preset matching model is not limited at all, and may be set according to actual conditions.
The attribute information directly used for the engineering quantity calculation of the target building model can be understood as attribute information which can be identified by the calculation quantity software and does not need to be converted again. And associating the attributes of the components to be matched with the attributes of the target components through intelligent matching by using the preset matching model, and determining the attributes of the target components corresponding to the attributes of the components to be matched.
It should be noted that the input data into the preset matching model may be the attributes of the members to be matched of all the primitives in the target building model, or the attributes of the members to be matched of one or some of the primitives selected by the user, and the like, where the data input into the preset matching model is not limited at all, and may specifically be input according to the requirements.
In the component matching method provided by this embodiment, the preset matching model is used to match the target component attribute of the component to be matched, where the target component attribute is attribute information that can be directly used for subsequent engineering quantity calculation. The method has the advantages that the preset matching model is utilized to match the attributes of the members to be matched into the attribute information which can be directly used for calculating the engineering quantity, so that the target building model can be directly utilized to calculate the subsequent engineering quantity, the quite complicated and time-consuming process of modeling is omitted, and the efficiency of calculating the subsequent engineering quantity is improved.
In this embodiment, a component matching method is provided, which can be used in the above-mentioned electronic devices, such as a computer, a mobile phone, a tablet computer, etc., fig. 2 is a flowchart of the component matching method according to the embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
and S21, acquiring the target building model.
Please refer to S11 in fig. 1, which is not described herein again.
And S22, analyzing the target building model to obtain the attributes of the members to be matched of the target primitives.
The attributes of the members to be matched of the target primitives can be sequentially performed on all the primitives in the target building model, and can also be performed on different floors.
For example, as shown in fig. 3, the electronic device analyzes the target building model to obtain floor information of each floor in the target building model, and then obtains the attributes of the members to be matched of the target primitives from the floor information. Fig. 3 is merely an example of the floor information, and it is also possible to specifically parse or show which information is set according to actual needs. The processing procedure of the preset matching model is described in detail in this embodiment.
In some optional implementations of this embodiment, the step S22 may include the following steps:
(1) and analyzing the target building model to obtain the floor information in the target building model.
And the floor information comprises attributes of the members to be matched of the primitives in each floor.
The electronic equipment can identify keywords of the target building model, determine each floor in the target building model, and extract floor information of each floor after each floor is determined. The floor information may include each primitive in the floor and component attributes of the primitive, and may further include elevation, height, and the like of the floor.
(2) And determining the attributes of the members to be matched of the target primitives based on the floor information in the target building model.
And after the floor information in the target building model is obtained, extracting the component attributes of the target primitive, and determining the component attributes to be matched of the target primitive.
For example, the electronic device may extract primitive information of each primitive in each floor information, where the primitive information includes a component type and a component material attribute corresponding to the primitive.
Please refer to S12 in the embodiment shown in fig. 1 for the remaining detailed steps, which are not described herein again.
And S23, inputting the attributes of the component to be matched into a preset matching model, and determining the attributes of the target component corresponding to the attributes of the component to be matched.
Wherein the target component attribute is information directly used for engineering quantity calculation of the target building model.
Whether the data input into the preset matching model is the floor information of all floors, or certain floor information, or the component attribute of a certain primitive, the preset matching model is processed aiming at the component attribute to be matched of each primitive in each floor information during internal processing.
For example, the floor information of a certain floor is input into the preset matching model, and the floor information includes attributes of the members to be matched of 4 primitives, so that the preset matching model performs matching conversion on the attributes of the members to be matched in sequence. Namely, when the floor information is input into the preset matching model, the preset matching model sequentially extracts the attributes of the members to be matched of each primitive in the floor information, and the target member attributes corresponding to the attributes of the members to be matched of each primitive are obtained.
Specifically, the step S23 includes the following steps:
and S231, extracting field features of the attributes of the component to be matched.
After the electronic equipment extracts the attributes of the components to be matched of the target graphic primitive, extracting the field characteristics of the attributes of the components to be matched. For example, the structure of the preset matching model employed in the present embodiment is shown in fig. 4. The model is used for intelligently identifying and associating the attribute information of the user uploading model in the same language or in a cross-language manner through a field matching technology, so that the component attributes in the BIM model can be accurately and intelligently matched.
The model generates the prediction text by a field matching method, and mainly comprises two stages of feature extraction mapping and text matching, although different languages have different grammatical structures and expression rules, semantic spaces of the languages often have similarity, so that a non-linear mapping relation can be realized by using high-dimensional feature spaces of text semantics.
For example, the preset matching model in the embodiment is established based on the ESIM algorithm, the algorithm has high precision and short global legs, and the related fields are decomposed into a word vector format for feature learning, which is more beneficial to fast self-learning of the algorithm. As shown in fig. 4, the attributes of the members to be matched are the types of the members and the material attributes of the members, for example, the types of the members including the building model, and the types of the members such as the wall, the beam, the plate, the column, the door and window, the foundation, etc. are input; and the material property fields of the components such as cast-in-place concrete, precast concrete, masonry, bricks, stones, glass and the like.
And after the field characteristics of the attributes of each component to be matched are extracted, performing characteristic coding on the field characteristics. For example, LTSM feature extraction coding is adopted, that is, a two-layer time-series neural network is called to perform learning and feature coding on an input word vector, and feature hidden values are recorded according to a time series.
In some optional implementations of this embodiment, if the target primitive is a merged primitive, it needs to be hierarchically extracted. For RVT model components, for example, different components made of multiple layers of materials may be added to the structure of a wall primitive, and thus intelligent layered extraction of different component installation materials is required. For example, as shown in fig. 5, for the floor.a-floor surface layer-30, which is a combination of three layers of materials, it is necessary to extract the field features for each layer of material attributes.
Specifically, the step S232 may further include the steps of:
(1) and judging whether the attributes of the components to be matched have at least two material attributes of the components.
For example, as shown in FIG. 5, the electronic device may determine for a field of a component material attribute of the target primitive. When the target graphic element has at least two component material attributes, executing the step (2); otherwise, directly extracting the field characteristics of the attributes of the members to be matched of the target graphic primitive.
(2) And extracting field characteristics according to the material attributes of the components.
And the electronic equipment respectively extracts the field characteristics of the material attributes of each component of the target primitive and performs subsequent matching conversion.
By extracting the field features of the component attributes to be matched in a layered mode, namely extracting the field features according to different component material attributes, the field features corresponding to different component types and the component material attributes in the target primitive are obtained, and the accuracy of the target component attributes corresponding to the target primitive is improved.
And S232, text prediction is carried out based on the extracted field characteristics, and the target component attribute is obtained.
Referring to fig. 4, after the field features of the attributes of the to-be-matched component are extracted in S231, a local inference step is performed, in which an attention model is mainly used, and the difference calculation analysis is mainly performed on the encoded feature values. The attention machine model is constructed to simulate human attention, high-value information is screened out from a large amount of information, the high-value information is mainly used for assisting in receiving and screening feature vectors output by the LSTM, and similarity matrixes and differences of two short texts are further calculated.
Further, after local reasoning, global reasoning is performed on the local reasoning, that is, global information is synthesized to perform reasoning synthesis on the features. Extracting context connection semantic information through the LSTM, and performing five-overlapping combination on all sub-areas in input features, namely splicing the features by adopting maximum pooling and average pooling to form complete semantic association.
And finally, performing text speculation prediction on the basis of global reasoning to obtain a target component attribute corresponding to the component attribute to be matched of the target primitive. Specifically, the obtained pooled semantic features are transmitted to a full connection layer and received by a classification function softmax, an activation function sigmoid is called to realize nonlinear mapping and classification in a multidimensional space, and a final predicted value is displayed in a form of a matching field.
Fig. 5 shows the corresponding expressions of the component type and the component material property before and after matching. Wherein, the first column in the left frame of fig. 5 represents the floor, and the third column represents the component material property in the floor information; the first column in the right frame of fig. 5 represents the thickness of the floor, the second column represents the matched component type, and the third column represents the matched component material property.
