Example one
The construction information model-based engineering supervision method can be applied to mobile devices such as mobile phones and notebook computers, and fixed devices such as desktop computers and televisions, and can supervise construction engineering according to the construction information model. Fig. 1 is a schematic flow chart of an engineering supervision method based on a building information model in this embodiment. Referring to fig. 1, the method for supervising an engineering based on a building information model includes steps 100, 200 and 300.
And step 100, obtaining a building information model.
In the engineering supervision process, the building information model to be examined is uploaded, so that the building information model is obtained.
And 200, examining the building information model through the building information knowledge graph to obtain an examination result.
Knowledge Graph (KG) as a new Knowledge representation method belongs to the category of semantic web, and aims to describe various entities and concepts existing in the real world and the association relationship between the entities and concepts, and capture and present the semantic relationship between the domain concepts. The knowledge graph mainly adopts (entity l, relation, entity 2) triple (SPO) form to represent knowledge, wherein, the entity (Endty) in the triple represents things or abstract concepts existing in the real world, and is represented by nodes in the knowledge graph, and the Relation (relationship) represents that a certain Relation exists between the entity and the entity, and is represented by directed connecting lines between the nodes.
The building information knowledge map is a knowledge map containing building information knowledge, and can be used for describing information knowledge in the building field. The building information knowledge map contains building regulation knowledge and semantic relations among the building regulation knowledge. Therefore, the building information model can be inspected according to the building code knowledge in the building information knowledge map, for example, the building code knowledge corresponding to the building information model data is searched through the building information knowledge map, and the building information model data is compared with the building code knowledge to judge whether the data in the building information model meets the building code, so as to obtain an inspection result.
And step 300, carrying out engineering supervision according to the examination result.
The examination result gives an examination conclusion and suggestion, related users are informed, and a supervision flow is determined according to the examination result, so that the supervision and management of the project are realized.
According to the engineering supervision method based on the building information model, the building information model is reviewed through the building information knowledge map, manual review in the engineering supervision process can be reduced, and the review, approval and approval efficiency of engineering projects can be improved.
Optionally, the building information knowledge graph is combined with information in the city information model, and the building information model is examined to obtain an examination result. For example, the building information model is inspected through the building information knowledge graph to obtain an inspection result, which includes steps 210 to 250.
And step 210, constructing a building information knowledge graph.
And constructing a building information knowledge graph according to the text of the building design specification and the building information model data. And performing word segmentation and part-of-speech tagging through the text of the building design specification to obtain a building entity in the building design specification, wherein the building entity comprises a parameter entity for determining the building design specification. Analyzing the attributes of the building entities, determining the mutual hierarchical relationship among the building entities, and determining the building information knowledge graph with the tree structure.
Step 220, obtaining a city information model.
The City Information Model (CIM) includes city information such as building information, infrastructure information, and geographic information in a city. The urban information model is a management platform integrating the functions of design management, examination and approval management, construction management, facility management, marketing, industry and the like.
And step 230, obtaining the examination data according to the information in the building information knowledge graph and the city information model.
It will be appreciated that building design specifications often also relate to some relevant parameters in the building surroundings, since the building and surroundings have an interactive relationship. For example, for the overall aesthetics of a city, building design requires that the height of a building not exceed two-thirds of the highest building height in the area surrounding the building. It can be seen that, for the above situation, data required by the building design specifications needs to be extracted from the city information model, thereby facilitating the comprehensive examination of the building information model.
For example, the building information knowledge graph extracts information in the city information model according to a preset rule; and combining the information extracted from the city information model with the building specification information in the building information knowledge graph to form the examination data.
And 240, extracting information in the building information model through the building information knowledge graph to obtain model data.
Because the information data in the building information model has the characteristic of multi-source isomerism, the data in the building information model needs to be extracted and integrated through the building information knowledge graph to form model data. For example, the attributes of the information data in the building information model are determined through a building information knowledge graph; and forming model data according to each information data and corresponding attributes in the building information model. Specifically, for one piece of data 20m in the building information model, the building information knowledge graph analyzes the building information model, and determines that the data 20m is the building total height of a certain building, that is, determines the correspondence between the data 20m and the building total height attribute.
And step 250, comparing the audit data with the model data to obtain an audit result. Specifically, each information parameter in the model data is compared with each corresponding information parameter in the audit data, and an audit result can be obtained.
It should be noted that, the steps 230 and 240 are independent from each other, and the order of the steps is not limited.
Optionally, a building information knowledge graph is constructed, including steps 211 through 216.
Step 211, obtaining a plurality of preset knowledge bodies and relations among the preset knowledge bodies.
The preset knowledge ontology is a knowledge concept acquired in advance about building information, and the knowledge concept is general information common to a plurality of knowledge entities. For example, the preset ontology may be a building type.
Step 212, an initial mode layer is constructed according to the preset knowledge bodies and the relation among the preset knowledge bodies.
The relation between the preset knowledge bodies is confirmed in a manual mode, and then an initial mode layer is constructed according to the plurality of preset knowledge bodies and the relation between the preset knowledge bodies, so that the correctness of the knowledge structure in the building information knowledge map is guaranteed.
And 213, acquiring the building information data, and extracting knowledge of the building information data to obtain a knowledge body and a knowledge entity.
The building information data includes a building design specification text and a building information model file. After the building information data is obtained, data cleaning and screening are needed to be carried out on various data, and word segmentation and part-of-speech tagging are carried out to meet the building information knowledge map building requirements. Optionally, a Chinese word segmentation method and a hidden Markov model-based method are adopted for word segmentation and part-of-speech tagging.
The knowledge extraction can automatically extract available knowledge units from the building information data after word segmentation and part-of-speech tagging, and the knowledge units mainly comprise 3 knowledge elements of knowledge entities, entity relations and entity attributes. And (4) selecting knowledge with higher confidence coefficient to abstract the concept to obtain a knowledge ontology. And the knowledge ontology is used for updating the constructed initial mode layer.
And step 214, completing the initial mode layer according to the knowledge body to obtain a mode layer.
And selecting knowledge with higher confidence level from the entities, attributes and relations obtained by the knowledge extraction technology to abstract concepts, and adding a new knowledge body into the initially constructed initial mode layer when the new knowledge body is found, so as to realize the updating of the mode layer.
Step 215, building a data layer according to the knowledge entities.
And constructing a knowledge entity network based on the knowledge entities, the relationship among the knowledge entities and the knowledge entity attributes to form a data layer. For example, knowledge entities, relationships, or attributes are added to data layers, continuously enriching and extending building information knowledge graphs.
And step 216, obtaining the building information knowledge graph based on the mode layer and the data layer.
Referring to fig. 2, the building information knowledge graph is composed of a schema layer 410 and a data layer 420, wherein the schema layer 410 is ontology 411 and the relationship therebetween, and the data layer 420 is entity 421 and the relationship therebetween, and the schema layer 410 and the data layer 420 are connected based on the relationship between the ontology 411 and the entity 421.
In the embodiment, the model layer of the building information knowledge graph is manually defined, and the knowledge ontology and the relation of the knowledge ontology are determined so as to ensure the correctness of the knowledge hierarchy structure; then, aiming at the well defined mode layer, performing knowledge fusion and knowledge processing on the extracted relevant knowledge in the building field data to complete construction of a building information knowledge map data layer; and finally, carrying out knowledge storage on the building information knowledge graph.
In addition, the building information knowledge graph has a cyclic updating process, and newly extracted knowledge can continuously update or correct the constructed knowledge graph.
Optionally, the information in the city information model is extracted through the building information knowledge graph to obtain the review data, including steps 231 to 234.
And 231, determining examination information according to the building information knowledge graph.
The examination information is used for examining the information of the building information model and is obtained from a building information knowledge map. The building information knowledge map contains the knowledge of building design specifications, and the examination information is determined according to the knowledge of the building design specifications and the relation between the knowledge and the building design specifications.
The form of the examination information may be the examination information in the form of a knowledge-graph structure, or may be the examination information in the form of a matrix.
In some embodiments, the review data is review information in the form of a knowledge-graph structure. For example, extracting knowledge for examination in the building information knowledge graph, and constructing an examination knowledge graph according to the examination knowledge; or directly intercepting part of the knowledge graph for examination from the building information knowledge graph to obtain examination information.
In some embodiments, the audit data is audit information in a matrix. For example, the knowledge for examination in the building information knowledge graph is extracted, and the extracted knowledge is arranged into a matrix according to the knowledge structure of the building information knowledge graph to obtain examination information. For example, in one piece of examination information [30, 3], the upper limit of the total building height and the lower limit of the story height are arranged, that is, 30 corresponds to the upper limit of the total building height, and 3 corresponds to the lower limit of the story height.
And step 232, determining the data needing to be supplemented according to the examination information.
Some of the audit information requires supplemental information, such as the height of surrounding buildings. In the review information in the form of the knowledge graph structure, the attribute corresponding to the information needing to be supplemented is at least data to be supplemented. For the examination information in the form of matrix, the information to be supplemented is represented by a special symbol, such as an "+".
And 233, searching the information in the city information model according to the data needing to be supplemented to obtain target data.
The city information model contains various city information data in the city, including public facility data and data of other buildings. For example, if the data to be supplemented corresponds to the building height of the highest building in the surrounding area of a certain building, the city information model is searched to obtain the building height of the highest building in the surrounding area.
And step 234, supplementing the examination information according to the target data to obtain examination data.
The target data is supplemented to the review information. And for the examination information in the form of the knowledge graph structure, adding the target data serving as a knowledge entity into the examination information, wherein the corresponding attribute is the building height of the highest building in the surrounding area. For the examination information in the form of a matrix, target data is replaced by information which needs to be supplemented in the matrix.
Optionally, information in the building information model is extracted according to the building information knowledge graph to obtain model data, including steps 241 to 244.
And 241, carrying out data standardization on the building information model to obtain a standardized building information model.
In the process of examining the building information model, the building information model has the characteristic of diversification, and data standardization needs to be carried out on the building information model to form data which can be analyzed by a building information knowledge graph.
For example, the data standardization of the building information model is realized by unifying the format of the building information model data. Optionally, the building information model is converted into data in an IFC standard format.
Step 242, analyzing the standardized building information model according to the building information knowledge graph to determine the type of the parameters in the building information model.
For example, based on the data in the IFC standard format, first, a building type entity and a component entity in the building information knowledge graph are respectively matched with item information in the basic information and the name of each component, and each component in the building type and building information model is determined; and matching the knowledge attributes in the building information knowledge graph with the attributes of each parameter in each component to obtain the type of each parameter (namely obtaining the meaning of each parameter). The type is determined from the component, the information attribute, and/or the geometric attribute. For example, the member is a cell, the height (height geometric property) of the cell is 3m, and the fire resistance rating (fire resistance rating information property) is one level; in the building information knowledge graph, a single room is one of the members and corresponds to two knowledge attributes, namely an information attribute and a geometric attribute, wherein the information attribute comprises a fire resistance grade, and the geometric attribute comprises a height; and respectively matching the knowledge attributes in the building information knowledge graph with the parameter attributes in each component to obtain a 3m type, and determining the type as the height between units, wherein the first level is the fire resistance grade between units. By determining the types of the parameters in the building information model, the matching and comparison of data are facilitated.
And 243, organizing the parameters in the building information model according to the types of the parameters to obtain model data.
For example, according to the position of the parameter corresponding to the building information model, the parameter arrangement sequence in the building information model is determined, and model data in a matrix form is formed. For example, a single room is 3.5m high and a door is 2.2m high, the model data may be [3.5,2.2] in order from whole to part.
Step 243 is an optional step, and in some cases, after the type of the parameter in the building information model is determined, the building specification value corresponding to the type of the parameter may be directly matched through the building information knowledge graph, and the parameter is compared with the building specification value, so that the inspection result may be obtained.
Optionally, the audit data is compared with the model data to obtain an audit result, including steps 251 through 253.
And 251, determining the corresponding relation between each parameter value in the model data and the corresponding standard value in the audit data.
And based on the types of the parameters in the model data, corresponding relations exist between the standard values in the audit data and the parameter values in the model data. For example, when the audit data is in the form of a knowledge graph, the type of each parameter is queried, and a standard value matched with each parameter is obtained from the audit data. For another example, when the audit data is in a matrix form, the standard values in the audit data are arranged according to the length, width and height of the room, and correspondingly, the parameter values in the model data are also arranged according to the length, width and height.
And 252, comparing the parameter values in the model data with the corresponding standard values in the audit data according to the corresponding relation, and determining whether the parameter values in the model data meet the standard requirements.
When the audit data is in the form of the knowledge map, after the standard values matched with the parameters are obtained from the audit data, the standard values in the audit data can be directly compared with the parameter values in the model data, and whether the parameter values in the model data meet the standard requirements or not is determined.
When the audit data is in a matrix form, all the standard values in the audit data are arranged according to the length, width and height sequence of the room, and then all the standard values in the audit data can be compared with all the parameter values in the model data in sequence to determine whether all the parameter values in the model data meet the standard requirements.
And 253, displaying the building information model in three dimensions, and marking components corresponding to various parameter values which do not meet the standard requirement to obtain a three-dimensional visual examination result.
And visually displaying the auditing result, specifically, three-dimensionally displaying the building information model in the city information model, displaying the parameters which do not meet the specification in the corresponding component position in the building information model, and displaying the detailed explanation on the illegal part of the building and the corresponding specification, thereby visually displaying the auditing result.
Optionally, engineering supervision is performed according to the examination result, including step 301.
And 301, generating engineering modification opinions when the examination result is unqualified.
And when the examination result is unqualified, entering a modification process, and feeding back the examination result to a designer of the building information model. The modification opinions are generated according to the examination result, for example, the reason that the examination result of a certain building is unqualified is that the total height of the building exceeds the upper limit height, and then the modification opinions 'the total height of the building exceeds the upper limit height and needs to be reduced' are automatically generated according to the corresponding rules.
Optionally, engineering supervision is performed according to the examination result, including step 302.
