Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of comprehensive design of buildings, and in particular to a scheme capable of timely discovering possible problems of components of a building when performing comprehensive design of the building. BACKGROUND

[0002] In recent years, with the development and progress of society, there are more and more urban construction and reconstruction projects in various parts of the country. The comprehensive design of buildings is an essential part of the design to be implemented in construction. The planning and design of buildings involves the participation of various trades, and the pipelines alone include, for example, water supply, gas, electricity, rainwater, sewage, and so on. The various functions required by these buildings are distributed in various corners and floors of the building, and their performance and purpose are different. Sometimes the design and construction are not carried out by the same department or company, and the construction time is usually sequential. Therefore, it is necessary to comprehensively design the space inside the building during the planning and design before construction, which can reduce or solve the problems that may occur between new and old components, between new components, and between components and the building during the construction of the building, and also facilitates the subsequent management and maintenance of the completed building.

[0003] In the traditional comprehensive design scheme of buildings, information exchange and judgment based on two-dimensional CAD drawings are mainly relied on. The CAD drawings are based on the planning and design data of various departments in building design, and the content is generally the preparation of building comprehensive planning drawings and longitudinal arrangement drawings of building cross sections. The main purpose is to determine the plane and longitudinal position of each main component of the building (the components can include various pipelines, beams, walls, floor layers, terraces, staircases, roofs, and doors and windows, etc.), and to solve the problems of overall space arrangement. For example, the arrangement of various pipelines inside the building on the road section is related to the design of the building cross section. When there are more pipelines concentrated in an area, in order to reasonably arrange the pipelines, it is sometimes necessary to widen the area, modify the internal design of the building, or modify the arrangement system of part of the engineering pipelines to reduce the number of pipelines in this space. In the detailed planning stage, based on the preliminary planning (or construction detail) data of each project inside the building, comprehensive plane drawings and part intersection elevation drawings are designed for the entire building project; the pipeline arrangement drawing on the building cross section is revised. The comprehensive design not only determines the plane position of the building, but also checks the vertical design inside the building to solve the problems of various components at the intersection. The comprehensive design made according to the preliminary planning data must be checked after the construction details of each project are completed.

[0004] However, how to discover the problems between the designs of various components of the building, such as collision, intersection, extrusion, interference, etc., based on the design or construction drawings from different departments during the comprehensive design is the most time-consuming and energy-consuming part of the comprehensive design scheme of buildings.

[0005] Although a number of software for building integrated design has been developed, and the software also provides a certain means of detecting problems, the existing mechanism for finding problems in building integrated design usually only considers one influencing factor or separately considers several factors, and cannot comprehensively consider all factors affecting building design, thus having great limitations. For example, when measuring whether the laying of two different types of building internal pipelines has a problem, the existing software usually only judges according to whether their burial depth and direction directly conflict, without comprehensively considering other factors such as the types, materials, specifications and environment of the two designs. In this way, some pipeline designs that seem to meet the requirements may expose many problems in actual construction and subsequent maintenance. These hidden problems can usually only be found by manual screening by designers or experience of on-site construction personnel.

[0006] On the other hand, in the existing three-dimensional building integrated design, due to the lack of a perspective means capable of displaying the integrated layout between different components inside the building through the three-dimensional surface of the building, it is difficult to find out whether there is a problem between different components of the building. For example, a pipe designer wants to check whether the pipe design conflicts with the building structure (such as wall, stairs, door, etc.) design, but the existing building integrated design software does not provide the corresponding function.

[0007] Therefore, the technical personnel hope to have a new mechanism that can comprehensively consider various factors affecting the internal design of the building during the building integrated design stage, and find out the potential problems between the components of the building by using perspective technology. SUMMARY

[0008] The present disclosure relates to a scheme for finding problems between components of a building during building integrated design, so as to provide an efficient, low-cost and accurate three-dimensional building design drawing, thereby reducing the subsequent construction and maintenance troubles.

[0021] Figure 6 An example flow diagram of a method for identifying problems in building integrated design according to an embodiment of the present disclosure is shown. Detailed Implementation

[0022] This disclosure relates to an improved scheme for identifying problems in various components of a building during the overall architectural design process. This scheme can flexibly and automatically discover various potential problems in architectural designs that are otherwise difficult to detect, without the need for time-consuming and laborious manual intervention. This improves the reliability and accuracy of architectural drawings, saves construction and maintenance costs, and greatly enhances the reliability of the building.

[0023] The following is combined Figure 4 The following example block diagram of an architectural integrated design system 400 including a graphical penetration analysis decision library model according to an embodiment of the present disclosure is used to describe the example structure and example flow of the present disclosure.

[0024] First, pipeline data collection and preprocessing must be carried out before pipeline design begins.

[0025] Data acquisition and preprocessing stage:

[0026] When a construction, renovation, or expansion project is required for a building, it is first necessary to obtain its planning drawings or specific data and drawings of existing facilities. Therefore, in the solution of this application, the building integrated design system 400 first provides a data acquisition module 402 for obtaining preliminary planning drawings of the building from one or more professional design companies or design departments.

[0027] Taking a building about to begin planning, design, or construction as an example, a preliminary planning drawing is typically provided by a specialized company, which also coordinates the design process. The preliminary planning drawings generally consist of a two-dimensional floor plan of the main structure and corresponding data sets, such as... Figure 1 As shown. However, the investigation only addresses potential problems within a single design department. Because data is not fully shared between design departments, this method can only identify partial floor plan design issues within the same department (type), such as pipework collisions, and cannot uncover problems between designs from different departments (types). Therefore, a comprehensive architectural design solution is ultimately needed.

[0028] Next, the preliminary planning map and / or geophysical exploration report are preprocessed using the data preprocessing module 404. The preprocessing includes data merging and 3D processing, thereby creating an integrated building BIM model (i.e., the original 3D design drawing).

[0029] Specifically, preliminary planning drawings from various professional companies for a certain type of building are preprocessed; these preliminary plans... Figure 1The preliminary plans are typically files such as a set of two-dimensional CAD drawings, each representing a type of building plan. After receiving all types of preliminary plans, all CAD drawings can be imported by a city planning software such as Civil 3D and merged using its merge function to integrate the pipelines into the same CAD drawing at the same time.

[0030] Subsequently, the integrated CAD plan can be three-dimensionalized to generate an integrated three-dimensional plan. For example, the three-dimensionalization of a segment of building pipe network is illustrated below by a piece of three-dimensionalization code and function that can be used to achieve the three-dimensionalization:

[0031]

[0032]

[0033]

[0034]

[0035]

[0036] In which, the cmdConvertPolylineToNetwork entry function is used to generate a 3D Civil 3D Network object from a 2D Polyline.

[0037] public List <networkcreationdata>The `GetNetworkDatas(string layerName)` method collects relevant Polyline information from a given layer, using it as input for generating the Civil 3D Network. Its main function is to identify all Polylines, Lines, and other objects, and then determine the Start Point and End Point based on their connectivity. It also saves all line segment information.

[0038] The `public ObjectId CreateNetwork(string name, PartListInfo plInfo, double pipeDepth, NetworkCreationData data)` function is the core function for generating the Network. Based on the Line information obtained from previous functions, it generates a Network object. Based on the layer information being processed, the object type can be obtained (e.g., water pipe, rainwater pipe, etc.), and then the PartList information can be obtained based on the type information. Combining the PartList and the previously obtained Line information, structure objects are generated one by one, then all pipe objects are generated, and finally, the pipe objects are connected to the connected structure objects, ultimately creating a connected Civil 3D pipe network.

[0039] The `public static void Fixup StructureRotation(ObjectId networkId)` method adjusts the rotation angle of a structure. The default rotation angles of generated structures are often incorrect, requiring manual adjustment using this statement. For example, it can be used to adjust the rotation angle based on the structure and connected pipe information.

[0040] Through the processing of the above series of codes, the integrated two-dimensional CAD planning drawing can be converted into a three-dimensional form, thereby creating the original integrated three-dimensional design drawing. The integrated three-dimensional design drawing can be a full-scene three-dimensional modeling of a three-dimensional BIM model established based on an architectural planning and design project, as shown in Figure 2(a) and Figure 2(b), where the former is a tilted view of the full scene of the three-dimensional BIM model, and the latter is a top view of the full scene of the three-dimensional BIM model.

[0041] Figures 3(a) and 3(b) further illustrate the magnified perspective tilt view and perspective top view of the 3D BIM model of the building.

[0042] In the three-dimensional design drawings, the architectural design drawings provided by various professional companies or various professional departments may have various problems (such as collision, interference, non-compliance, etc.) after integration. Some of these problems can be automatically identified by using existing software, for example, direct collision and intersection of pipelines in the building, but some still need to rely on the experience of technical personnel to manually check. Such manual checking is not only time-consuming, but also not comprehensive, and some problems may be missed. Therefore, a solution is needed to quickly and comprehensively check various hidden dangers in the original three-dimensional design drawings. To this end, as described below, the present disclosure provides a graphic model penetration analysis decision library model to solve the above problems.

[0043] Graphic model penetration analysis decision phase:

[0044] As previously described, the architectural integrated design system 400 first includes a data acquisition module 402 and a data preprocessing module 404 to realize data acquisition and preprocessing operations to create an integrated three-dimensional architectural BIM model. After the model is built, the architectural integrated design is changed from analysis based on plan drawings to analysis on three-dimensional models with height attributes.

[0045] In the monitoring link in the previous integrated design, multiple design departments often need to continuously adjust each other's plan design to realize the unity or coordination of various architectural design components in space material, etc. This process is based on plan drawing analysis in previous stages. Even if the height data is marked in the plan drawing, visual analysis or detailed adjustment often requires designers or integrators to spend a lot of time and effort to draw elevational section views for monitoring. Since the design of each architectural component is relatively independent, even if this monitoring process is time-consuming and labor-intensive, it is an important part of architectural integrated design that cannot be ignored.

[0046] According to the above data acquisition and preprocessing stage, the data of multiple departments in architectural design is integrated, and finally an integrated original three-dimensional design drawing (i.e. an architectural three-dimensional BIM model) is formed. Through the three-dimensional BIM model, designers have a clearer understanding of the components of the architectural design. Some more obvious design conflicts can be directly exposed visually. For example, the conflict between the ventilation pipeline and the fire pipeline, which needs to be repeatedly compared by the designer in the previous inspection and integration stage to complete the cognition of the entire drawing, but now the direct conflict can be directly observed, and it can be found simply and quickly.

[0047] Obviously, in addition to the detection that can be achieved directly through observation, there are many problem detections that need more detailed comparison, and even need to rely on mathematical models. For example, when a certain building component needs to avoid a certain distance (that is, a certain buffer area needs to be constructed), the direct observation of the three-dimensional model cannot solve such problems; and the profile analysis calculation from various dimensions is time-consuming and laborious.

[0048] In order to solve the above problems, the present disclosure provides a graph model penetration analysis decision library model 406, in which various problems that can occur in pipeline design are classified into several sub-libraries. Each sub-library stores parameters, variables, functions, formulas, samples, codes, etc. related to the characteristics of such problems. Once some data in the input three-dimensional design graph matches the characteristics in the sub-library, the decision library model 406 will actively issue an alarm and provide a related report of the problem that occurs for the designer to refer to and modify the design graph.

[0049] Among them, "graph" in "graph model" refers to two-dimensional plan drawings mainly in CAD type; and "model" refers to BIM building three-dimensional models. "Graph model penetration" is to use two-dimensional plan drawings as the sectioning surface, and hide the cut building model part, so that the internal structure of the building model can be seen.

[0050] For the convenience of understanding, in Figure 4 , several example sub-libraries of the graph model penetration analysis decision library model 406 are shown. As shown in the figure, the graph model penetration analysis decision library model 406 can include: a graph model penetration analysis library, Building a specification standard library, a building material material quality library, a green building sustainable development library, and other sub-libraries.

[0051] The structure and function of the penetration analysis decision library model 406 will be described in detail below in combination with each sub-library.

[0052] Figure 5(a)

[0053] Firstly, the graphic penetration analysis library is mainly configured for three-dimensional collision analysis of the design drawing and the building component of the planning design in the horizontal position and the intersection position based on the building three-dimensional BIM model, and whether there is a collision relationship between various components is obtained through a space algorithm. The collision analysis can be divided into the following steps: 1) control the position of the two-dimensional drawing (such as a two-dimensional CAD plan drawing); 2) obtain the position of the two-dimensional drawing relative to the building three-dimensional BIM model, and pass the position to the Shader; 3) in the Shader, control which part of the model is visible according to the position of the imported drawing; 4) use space vector analysis to preliminarily judge whether there is a collision between the components of the building (rough selection); 5) for components that may collide, calculate the minimum distance between them, and then determine whether they really collide based on the minimum distance (accurate analysis).

[0054] Specifically, as Building code library With 5(b) The penetration diagram of the design drawing of CAD and the building three-dimensional BIM model is shown, the white semi-transparent layer at the top is the added CAD design drawing, the base is the building three-dimensional BIM model built according to the design planning, and the darker gray line elements and surface elements on the top and bottom are the positions where the CAD design drawing and the building three-dimensional BIM model intersect.

[0055] Because the CAD design drawing is a two-dimensional plan drawing, and the building three-dimensional BIM model is a three-dimensional model, the latter has one more Z axis than the former, that is, the data in the vertical design. Therefore, if you need to display the three-dimensional building perspective according to the position of the CAD design drawing, you first need to adjust the imported CAD design drawing to the height of the building three-dimensional BIM model we need to monitor. This has been described in detail in the three-dimensionalization program of the CAD planning drawing in the data collection and preprocessing stage.

[0056] On this basis, for example, if the pipe designer of the building wants to check whether the pipe design conflicts with the building structure design, they can penetrate the building three-dimensional BIM model by dragging their plan drawing on the longitudinal and transverse sections, and observe whether there is a collision to make a judgment. If the above operation and judgment are described in code, it can be implemented as follows:

[0057]

[0058]

[0059]

[0060]

[0061] According to the above process, the inserted CAD planar design drawing can be moved in the Z-axis in the building three-dimensional BIM model. The pipeline designer can control the longitudinal movement of the CAD design planar drawing in the building three-dimensional model through the grab handle. This process is important in the graphic model penetration analysis, because it directly determines the relative position of the graphic model, and is the position that the designer can directly operate.

[0062] The above process only determines the relative position of the planar design drawing and the building model in the graphic model penetration analysis process, and does not realize penetration, so the designer cannot see the specific structure of the three-dimensional building.

[0063] Then, on this basis, a penetration visual effect needs to be established for the longitudinal position of the graphic model. This can ensure that when the designer moves the two-dimensional CAD planar design drawing in the longitudinal direction, the penetration effect of the moved CAD planar drawing and the three-dimensional building BIM model can be observed in real time. For example, when the pipeline designer moves the planar design drawing, the penetration effect of the pipeline CAD planar design drawing and the three-dimensional building BIM model can be observed, so as to achieve the purpose of modifying the pipeline design by comparing the building structure model. To complete this process, the longitudinal position of the CAD planar design drawing in the building three-dimensional BIM model needs to be extracted first.

[0064] This process can be implemented through the following example code:

[0065]

[0066] According to the above process, the position of the CAD planar design drawing in the longitudinal axis of the building three-dimensional BIM model can be extracted. After knowing the longitudinal relative position of the CAD planar design drawing, data needs to be transmitted to the Shader. Because the visualization effect of the present application needs to display the CAD planar design drawing and the building three-dimensional BIM model at the same time, the building three-dimensional BIM model needs to be analyzed according to the height position of the CAD planar design drawing, so as to realize the simultaneous display of the CAD planar design drawing and the building perspective view corresponding to the height.

[0067] This process can be implemented through the following code:

[0068]

[0069]

[0070]

[0071] The above steps achieve the perspective observation of the two-dimensional design drawing and the three-dimensional building model. Through the last step, the height position of the inserted CAD two-dimensional design drawing is determined, and then the height data is transmitted to the Shader, so that the Shader selectively displays and shields the corresponding part of the building three-dimensional BIM model according to the height position, thereby achieving the perspective effect.

[0072] The above software codes and functions can be implemented and found in three-dimensional design software such as Unity3D.

[0073] For example, when the building is in the design planning stage, the designer can use this perspective function to compare the designed building block such as the staircase with the position of the window with the designed pipeline part, and observe whether the two building components will have a possible conflict in space. The pipeline designer can constantly move their pipeline plan drawing on the three-dimensional BIM model of the building to constantly move and observe the conflict with the building structure at each level. After finding out, the three-dimensional model or CAD plan of the problem part can be redesigned in time, greatly simplifying the work burden of the designer.

[0074] In the existing and previous building comprehensive design, the personnel of multiple building design parts need to constantly adapt to find the best spatial arrangement that can accommodate all building components, such as pipeline personnel who need to constantly change the design according to the weight of the structure drawing. In this process, two-dimensional plan CAD drawing is the most common data transmission mode. However, for designers, constantly analyzing and checking two-dimensional drawings to plan and design is a time- and energy-consuming process. The three-dimensional perspective of the present application can be achieved in cross-section and longitudinal direction, greatly reducing the burden of workers at this step and improving work efficiency.

[0075] In addition, when the building is in the construction stage, the construction personnel can use this perspective function to further compare the differences between the completed building block and the designed part, or present and observe the problems in the actual construction through the building BIM three-dimensional model, and preferentially modify and detect the feasibility in the model to avoid encountering more difficulties in subsequent construction.

[0076] When the building perspective analysis cannot meet the needs of the designers or the construction personnel, for example, a certain building component does not collide with other parts of the model in the observed model, but some parts are very close to each other, then vector calculation is needed on the basis of the perspective building model. Still taking the pipeline and the building component (for example, the wall) as an example, there may be a case that the pipeline does not collide with the wall in a visual manner, but a certain segment of the pipeline is very close to a certain part of the wall, less than a preset threshold, and the minimum distance between the pipeline and the wall at this place can be calculated. The minimum distance is compared with the pipe diameter to determine whether there is a collision.

[0077] When the pipeline collides in the space of the building, the system will record the results of the collision analysis, which indicates, for example, where the existing facilities of the building collide with the planned pipeline, or where the planned pipelines collide with each other, etc. According to the results, the designers can redesign the planning of the relevant pipelines or building components in the original three-dimensional design drawing to avoid the collision.

[0078] If there is no collision relationship between the pipelines, the process can enter the next decision sub-library.

[0079] It should be understood that although the collision between the pipeline and the wall is mainly taken as an example of checking the problems of the building components in the above embodiment, in fact, the problem checking between other building components is also applicable to the graphic model penetration analysis, for example, whether the placement positions of the equipment and the doors and windows in the building conflict. Here, no longer one by one.

[0080] Building material library

[0081] In order to reasonably use the urban land, arrange the design of the building, guide the construction of the building, coordinate the relationship between the design departments or companies of the building, and provide the basis for the preparation and management of the engineering comprehensive planning, the relevant departments have formulated many unified standards or specifications related to the building profession, including but not limited to: "Building Design Fire Prevention Code" GB 50016-2014 (2018 edition);

[0082] "Unified Standard for Civil Building Design" GB 50352-2019;

[0083] "Code for Calculation of Building Area of Building Engineering" GB / T 50353-2013;

[0084] "Standard for Construction Quality Acceptance of Building Foundation Engineering" GB 50202-2018;

[0085] "Standard for Energy Saving Design of Public Buildings" GB 50189-2015;

[0086] Code for Design of Building Water Supply and Drainage GB 50015-2019;

[0087] Code for Vertical Planning of Urban Land Use CJJ 83-99;

[0088] Technical Specification for Concrete Structures of Tall Buildings JGJ 3-2010;

[0089] Code for Design of Residential Buildings GB 50368-2005;

[0090] Code for Design of Office Buildings JGJ / T 67-2019;

[0091] Code for Construction Quality Acceptance of Building Ground Engineering GB 50209-2010.

[0092] Most of them are national standards, and some of the provisions are mandatory provisions that must be strictly enforced. Therefore, when performing three-dimensional design of buildings, a relevant standard library also needs to be constructed to find out problems in building design that do not meet the specifications.

[0093] For example, in Code for Design of Low Voltage Distribution GB 50054-2011, the minimum width of the distribution screen passage arranged in a row is specified, and various situations are also subdivided. For specific situations, see the following table.

[0094]

[0095] Table 1: Minimum width of distribution screen passage arranged in a row (m)

[0096] In order to find out whether the original three-dimensional design drawing has problems that do not meet the specifications, first, the specification requirements in the above table are entered into the building specification standard library as preset conditions. When checking, the relevant data of each building component in the building design drawing can be read, and the minimum horizontal spacing, minimum vertical clearance and other data related to the standard of various building components can be obtained by calculation, and then they are matched with the corresponding specification requirements in the building specification standard library, and then the layout of the three-dimensional body in the three-dimensional design drawing is determined according to the matching result whether it meets the specification requirements.

[0097] In this way, by comparing each building component and the related parameters between them after calculation with the specified values in the specification, it can be automatically determined whether all three-dimensional bodies meet the requirements of the specification. If the building components meet all the specification requirements, the process can proceed to the next decision sub-library.

[0098] If the building design does not comply with one or more of the standards, the standard library can store records indicating which building blocks do not comply with which standard, or provide a final standard report presenting all non-compliance issues. According to the records or reports, the designer can redesign the three-dimensional design plan to comply with the corresponding standard requirements.

[0099] It should be understood that the above table is only used to illustrate a specific building standard for the purpose of illustration, and the table can actually contain more or less defined rules, and can be implemented in other forms other than tables. Other building standards can also be introduced into the building standard library in a similar form and matched as described above, which is within the scope of the present disclosure.

[0100] Green building sustainability library

[0101] After the building standard analysis is completed, a building material material library can also be provided, which proposes relevant requirements for the materials and materials used in the building. In traditional building integrated design, these factors generally depend on human experience and are not systematically added to the building design system. For example, a designer who has lived in a southern city for a long time may consider the prevention of dampness more carefully when designing a building, but if the design is done by a designer from a northern city, the designer may overlook this factor or underestimate the possible negative impact of dampness. Building material national standards include but are not limited to the following standards:

[0102] "Decorative concrete brick" GB / T 24493-2009;

[0103] "Construction with pebbles, gravel" GB / T 14685-2011;

[0104] "Construction with sand" GB / T 14684-2011;

[0105] "Limestone powder concrete" GB / T 30190-2013;

[0106] "Marine portland cement" GB / T 31289-2014;

[0107] "Natural marble building board" GB / T 19766-2016;

[0108] "Dry hanging decorative stone" GB / T 32834-2016;

[0109] "Aluminum-plastic composite board for building curtain wall" GB / T 17748-2016.

[0110] For example, in the "aluminum-plastic composite panel for building curtain wall" standard, the thickness, size, appearance, coating performance (oil resistance, alkali resistance, hydrochloric acid resistance, solvent resistance, artificial climate aging resistance, etc.), and physical and mechanical properties of aluminum-plastic composite panels are clearly specified. Traditional architectural design must take into account various performance attributes, which is difficult and prone to human error. By inputting these indicators and specifications into the building material material library, the graphic model penetration analysis decision model 406 will automatically analyze the materials of the relevant components in the architectural design drawing and compare them with the material requirements of the corresponding components in the building material material library. If there are any issues that do not meet the specifications, a problem report can be generated, and the material quality and location of the building components that do not meet the requirements can be displayed.

[0111] Similarly, the above national standards and examples are shown for illustrative purposes only and are not intended to be limiting. There are many more relevant national standards that can be added to the library.

[0112] Figure 6

[0113] In today's society, the concept of "green" is becoming more and more popular. As a result, the green building sustainable development library aims to monitor the construction of high-quality buildings that save resources, protect the environment, reduce pollution, provide healthy, suitable, and efficient use of space, and maximize the harmonious coexistence of people and nature throughout the life cycle.

[0114] In accordance with the "Green Building Evaluation Standard" GB / T50378-2014, China's green building standards are not mandatory at this stage. However, the sustainable development of buildings is a necessary process in the long run, not only for the consideration of future generations of humans who need buildings, but also to provide a better user experience for humans living in buildings today. The indoor layout of green buildings is very reasonable, minimizing the use of synthetic materials, making full use of sunlight, saving energy, and creating a natural feeling for occupants. With the goal of coordinated development of people, buildings, and the natural environment, it aims to create a good and healthy living environment using natural conditions and artificial means while minimizing the use and destruction of the natural environment, fully embodying the balance between taking and giving back to nature

[0115] The green building evaluation index system should consist of five categories of indicators: safety and durability, health and comfort, convenience of life, resource conservation, and environmentally friendly living. Green building evaluation should be conducted after the completion of building engineering. Pre-evaluation can be conducted after the completion of architectural engineering construction drawing design. The green building rating is divided into three levels from high to low: three-star, two-star, one-star, and basic level.

[0116] This green building sustainable development library emphasizes the pre-screening and judgment of the internal environment of the building to achieve the completion and level of green building standards through the three-dimensional model of the building BIM before the building is completed. This library contains Thermal Issues, Daylighting, and Air Quality.

[0117] Thermal Issues. Thermal comfort significantly affects work efficiency. Traditional air conditioning systems can maintain indoor temperature, but recent studies show that achieving absolute comfort indoors can easily lead to "air conditioning disease" problems and consume a large amount of energy, increasing the destruction of the ozone layer by freon. Green buildings require not only to ensure the overall thermal balance of the human body but also to pay attention to the special requirements of individual parts of the body such as the head and feet for temperature and to be good at using natural energy. In addition, the commonly used large glass surface buildings can cause greenhouse effect in summer and low temperature radiation effect from cold glass in winter.

[0118] Daylighting. Indoor light environment directly affects work efficiency and indoor atmosphere. Introducing pollution-free, good light color sunlight as a light source in green buildings is part of the green light environment. But a comfortable and healthy light environment should also include easy-to-view, safe and beautiful brightness distribution, glare control, and uniformity control of illumination, etc., so the strong light should be adjusted according to different time and place to not affect the high quality of sunlight.

[0119] Air Quality. Factors that usually affect air quality include air movement, air cleanliness, etc. If air movement is not enough, people will feel uncomfortable, and if it is too fast, it will affect temperature and cleanliness. Therefore, appropriate fresh air volume should be adjusted according to different environments to control air cleanliness and flow rate so that air quality reaches an optimal state. At the same time, effective control of indoor air pollutants is also one of the main ways to improve indoor environment. There are thousands of pollutants that affect indoor air quality. Green buildings believe that not only should the concentration of pollutants in the air be below the recognized harmful concentration index, but also the vast majority of people in the indoor environment should be satisfied with the indoor air quality index.

[0120] Buildings are not only for human service, sometimes need to consider the building purpose, such as storage and work room. Due to the diversity of building functions, the green building sustainable development library supports high degree of freedom of customization. Therefore, the degree of freedom of the green building sustainable development library is important, which enables users to define the required thermal comfort level according to local climate conditions, or the optimal indoor storage temperature, so that the evaluation is more practical. According to the temperature selection of the building material and the volume of the building interior, the green sustainable development level of the building is predicted according to the set thermal comfort level, and the designer can modify the BIM three-dimensional model of the building based on this.

[0121] Similar to the previous library, the above standard requirements can be embodied as preset conditions in the green building sustainable development library, and whether there are problems that do not meet the green building can be checked by comparing with the corresponding data of each component in the building design.

[0122] After the checking of each sub-library in the building comprehensive design system report module 408 can separately issue a problem checking report for each sub-library, or can also summarize the problems found in each sub-library to issue a comprehensive problem checking report. The problem checking report can include the type of problem, the involved building components, location, coordinates, etc. Moreover, the problem checking report can be in various forms such as charts, spreadsheets, documents, etc. According to this information, the designer can manually correct these problems in subsequent design, or confirm the relevant modification suggestions given by the system after the system gives the relevant modification suggestions.

[0123] It should also be understood that the sub-libraries contained in the above-mentioned building model penetration analysis decision library model 406 are only described for illustrative purposes. In fact, a skilled person can add more sub-libraries to adapt to the discovery requirements of new problems, or reduce the number of sub-libraries to improve processing speed and save resources. These changes are within the scope of the present disclosure.

[0124] It should be understood that the various modules in the example system can be connected to each other and transmit information through wired (such as cable) / wireless (such as WiFi, Internet, Bluetooth, NFC, etc.) communication links and technologies.

[0125] In Figure 6 , a method 600 for discovering problems in building comprehensive design according to an embodiment of the present disclosure is shown. According to the method, possible problems in various aspects can be automatically checked from the original three-dimensional design drawing constructed based on the building design plan, without human intervention. Thus, a fast, efficient and low-cost building comprehensive design scheme is provided.

[0126] like Figure 1 As shown, firstly, in step 602, architectural design drawings are obtained from the parties involved in the architectural design. As previously mentioned, these architectural design drawings encompass various aspects of the architectural design, such as type, materials, pipe diameter, etc. The preliminary planning... ​ Generally, CAD drawings are used, but other formats such as Excel spreadsheets are also possible.

[0127] After obtaining the preliminary planning and design drawings, in step 604, data preprocessing needs to be performed on these data.

[0128] The preliminary planning drawings (e.g., CAD drawings) from various professional companies are merged into an integrated architectural design drawing, and this integrated design drawing is then rendered in 3D to generate an integrated 3D architectural planning drawing. This process has already been described in detail in the "Data Preprocessing Stage" and will not be repeated here.

[0129] Subsequently, after completing the aforementioned data preprocessing steps, in step 606, the image-model penetration analysis decision library model is used to investigate various types of problems existing in the original 3D design drawings, as well as in the 2D design drawings and 3D models. The image-model penetration analysis decision library model may include, for example, an image-model penetration analysis library, a standard library, a material library, a green building sustainability library, and other custom sub-libraries. Each sub-library can investigate the original 3D design drawings for a specific type of problem to find whether the observed design drawings have issues. The specific working process of each sub-library has been described in detail in the "Image-Model Penetration Analysis Decision Stage" section above and will not be repeated here. It should be understood that the three sub-libraries illustrated in the image-model penetration analysis decision library model are merely for illustrative purposes. In practice, technicians can add more sub-libraries according to design and construction needs to adapt to the investigation requirements of new problems, or reduce the number of sub-libraries to improve processing speed and save resources. This is all within the scope of this invention. For example, if the building design has special environmental or historical preservation requirements, additional libraries such as environmental standards libraries and historical style standard libraries can be established. By entering the relevant environmental and landscape protection requirements into these libraries as described above, it is possible to assess whether the architectural design meets these requirements.

[0130] Finally, in step 608, multiple problem investigation reports corresponding to each sub-library are generated, or a comprehensive problem investigation report is provided directly for designers to review. The problem investigation report may include the type of problem, the building components involved, location, etc. Designers only need to consult the problem investigation report to gain a basic understanding of the various problems existing in the original 3D design drawings or the corresponding CAD plan design drawings, thereby enabling them to make targeted modifications to the design drawings.

[0131] Meanwhile, since the problem discovery mechanism is based on the building three-dimensional BIM model, the designer often needs to recheck after discovering the problem, and this process is also based on the building three-dimensional BIM model. In order to avoid the repeated work of the designer and improve the work coordination, the building components can be adjusted directly in the building three-dimensional BIM model to achieve the one-time completion of the check change in the building three-dimensional BIM model. The building three-dimensional BIM model after the change design can be output into a CAD design plan model, avoiding the tedious process of drawing a CAD plan design from a three-dimensional model and the possible problems accompanying it.

[0132] Compared with the existing solution mainly relying on manual checking of problems in the building design, the building comprehensive design solution of the present disclosure makes full use of the processing capacity of the computing resources to replace manual labor, not only improving the efficiency, but also avoiding the omissions and errors that are prone to occur when checking manually. In addition, in some embodiments, new samples can be added to the sub-library by adding new parameters, rules, etc. to discover new problems, the type range of the problems to be checked can be expanded by constructing new sub-libraries, or some sub-libraries can be selected or skipped to speed up the checking. Therefore, the building comprehensive design solution of the present disclosure is more flexible and efficient.

[0133] The above describes specific embodiments of the present disclosure. Other embodiments are within the scope of the appended claims. In some cases, the acts or steps recited in the claims can be performed in a different order than the order described in the embodiments and still achieve the desired results. In addition, the processes depicted in the figures do not necessarily require the particular order shown or sequential order to achieve the desired results.

Moreover, one skilled in the relevant art will appreciate that the embodiments can be practiced with variations of the steps or in different orders without departing from the spirit and scope of the present disclosure as defined by the appended claims.
