Description

Technical field:

[0001] The present invention belongs to the technical field of architectural design and materials, and specifically relates to an intelligent inspection and automatic matching method for local materials adapted to the high-altitude cold climate in northern China. Background technology:

[0002] The northern high-altitude climate encompasses extremely cold winters, scorching summers, strong sandstorms, and dryness. As a typical northern high-altitude cold region, the Inner Mongolia Autonomous Region, due to its unique and harsh climatic conditions, places extremely high demands on the selection of building materials. Incorporating natural local materials has become a core concept in architectural design in the Inner Mongolia Autonomous Region. Local materials refer to materials relevant to the local area used in building design and construction. These materials are typically locally produced or readily available, and are adapted to the local environment and climate. The selection of local materials not only affects the structural stability of the building but also its adaptability to the extreme climate of the Inner Mongolia Autonomous Region. This context necessitates that our technological innovations focus on solving complex challenges such as intelligent inspection and automatic matching of local materials in extreme climates. Summary of the invention:

[0003] The purpose of the present invention is to provide a method for intelligent inspection and automatic matching of local materials that can adapt to the high-altitude and cold climate in the north. The method performs intelligent inspection and automatic matching of local materials based on structural stability and climate suitability, solving the problem that the materials selected for traditional architectural design in the Inner Mongolia Autonomous Region are not close enough to the actual conditions of local climate and terrain, are not adaptable enough to extreme climate environments, and do not fully consider the regional differences in the Inner Mongolia Autonomous Region, resulting in a lack of targeted selection of building materials and a failure to give full play to the advantages of local natural resources.

[0004] The present invention is implemented by the following technical solution: a method for intelligent inspection and automatic matching of local materials adapted to the northern cold climate, comprising the following steps:

[0005] Step S1: Collection of basic site data,

[0006] Obtain climate and environmental information of the target city from the local meteorological department through a data interface; use a 3D laser scanner to obtain 3D point cloud data of natural soil and rock within the target site and surrounding buffer zone, and use a point cloud classification algorithm to classify the natural soil and rock materials within the target site and surrounding buffer zone. The obtained natural soil and rock materials are then classified, numbered, and counted, ultimately constructing an information set of natural local materials for the target site;

[0007] Step S2: Collection of target site building case data set,

[0008] Retrieve design proposals and basic design proposal information within the control area of ​​the planning bureau where the target site is located; perform 3D modeling of architectural elements for all winning architectural design proposals in the geographic information system to construct a case dataset for the target site's architecture;

[0009] Step S3: Construction of standard model library of target site,

[0010] Based on the climate and environmental information of the target city obtained in step S1, a target site building case set that matches the climate and environmental conditions of the target site is screened from the target site building case data set obtained in step S2, and the set is exported to the building modeling software; the local natural materials described in step 1 are used as alternative building materials, and the selected target site building case set that matches the climate and environmental conditions of the target site is filled with building materials using the building modeling software; and finally, the set is input into the geographic information system to construct a target site standard model library;

[0011] Step S4: Structural stability test of the building standard model,

[0012] Input the standard building models in the target site standard model library obtained in step S3 into the computational fluid dynamics simulation system one by one, and set the climate environment simulation parameters of the computational fluid dynamics simulation system according to the climate environment information of the target city obtained in step S1; then perform a structural stability test on the standard building models of the target site by calculating wind loads and snow loads, and mark the standard building models that pass the structural stability test as candidate building models for the target site;

[0013] Step S5: Automatic matching of climate suitability of “building-material”,

[0014] Perform indoor air circulation simulation and thermal comfort index calculation for the candidate building models of the target site marked in S4 by season and time. Then, evaluate the thermal comfort level of the building with reference to the "Code for Design of Heating, Ventilation and Air Conditioning for Civil Buildings (GB50736-2012)". Using the building climate adaptability matching model, automatically match the "building element-building material" combination relationship that meets the thermal comfort standard, and generate a set of preferred building solutions.

[0015] Step S6: holographic large screen selection and building material information output.

[0016] In the geographic information system, the preferred building plans obtained in step S5 are placed into the site environment one by one, and the model main information and thermal comfort simulation results are displayed and compared on a holographic large screen. The above contents are integrated into a building material matching report and printed in Word / Excel format.

[0017] Furthermore, the climate environment information of the target city obtained in step S1 includes the maximum wind pressure, the maximum snow pressure, and the climate of the city, which includes the mid-temperate humid zone, the mid-temperate semi-arid zone, the mid-temperate arid zone, and the cold temperate humid zone.

[0018] Furthermore, the classification of natural soil and rock materials within the target site and the surrounding buffer zone in step S1 refers to dividing the natural soil and rock materials within the target site and the surrounding buffer zone into sand, clay, crushed stone, gravel, elm, and birch according to the "Engineering Rock Mass Classification Standard (GB / T50218-2014)", "Engineering Classification Standard of Soil (GB / T 50145-2007)", and "Wood Structure Design Standard (GB 50005-2017)". Among them, the target site refers to the land red line, and the buffer zone around the target site is based on the land red line. The spatial buffer tool is used to generate a 15-minute reachable range circle, and its specific range can be set as 1000 meters in accordance with the "Guidelines for the Construction of Complete Residential Communities".

[0019] Furthermore, the design scheme and basic information of the design scheme within the control scope of the local planning bureau described in step S2, the basic information of the design scheme includes two pieces of information: building function type and climate environment to which the building case belongs; wherein, the building function type can be divided into cultural and educational buildings, commercial service buildings, and residential and livelihood buildings according to the "Construction Engineering Classification Standard (GB / T 50841-2013)", and the climate environment information to which the building case belongs can be divided into temperate humid zone, temperate semi-arid zone, temperate arid zone, and cold temperate humid zone according to the "Yearbook of the People's Republic of China (2022)".

[0020] Furthermore, the three-dimensional modeling of building elements in step S2 refers to modeling the building structure wall A, the building surface wall B, and the building top roof C separately in the geographic information system; wherein the structural wall is created one by one according to the floor plan of the building, and the parameters including the height, thickness, and length of the wall are determined; the building surface wall is created according to the design drawing of the building surface, and the shape, opening, and decorative details of the surface wall are determined; the building top roof is created according to the roof design drawing of the building, and the slope and height difference parameters are ensured to be set correctly.

[0021] Furthermore, the target site building case dataset in step S2 specifically includes building case number, case name, award name and level, geographical location, climate environment, building function type, and building main body form data attributes. The attribute values ​​are as follows:

[0022] Building Case Properties: Property Value;

[0023] Building case number: natural number;

[0024] Case name: full name of the case project;

[0025] Geographic location: three-dimensional coordinates of the case project space;

[0026] Climate environment: mid-temperate humid zone, mid-temperate semi-arid zone, mid-temperate arid zone, cold temperate humid zone;

[0027] Building function types: cultural and educational, commercial and service, residential and livelihood;

[0028] Main building vector file: including structural walls, surface walls, and top roof.

[0029] Furthermore, the step S3 of filling the selected target site building case set that matches the climatic and environmental conditions of the target site with building materials using the building modeling software specifically includes the following steps:

[0030] Determine the permutations and combinations of "building elements-building materials" and traverse all permutations and combinations of "building elements-building materials" using a recursive algorithm. The building elements include building structure walls A, building surface walls B, and building roofs C. The building materials include sand M1, clay M2, crushed stone M3, gravel M4, elm M5, and birch M6. There are a total of 216 permutations and combinations of all the "building elements-building materials";

[0031] Filling building materials: Using building modeling software, fill building materials into the selected target site building case set that matches the climatic and environmental conditions of the target site in accordance with the arrangement and combination of "building elements-building materials";

[0032] Build a standard model library of the target site, input the filled target site building case model into the geographic information system, and build a standard model library of the target site.

[0033] Furthermore, the standard model library of the target site in step S3 includes a building case number, a case name, a geographical location, a climate environment, a building function type, and a main building form.

[0034] Furthermore, the climate environment simulation parameters of the computational fluid dynamics simulation system in step S4 are used to perform structural stability testing on the target site climate obtained in step S1, and the climate environment simulation parameters specifically include the wind vibration coefficient β at height z z , wind load shape coefficient μ s , wind pressure height variation coefficient μ z , basic wind pressure w0, roof snow distribution coefficient μ r, basic snow pressure s0, where basic snow pressure and basic wind pressure are obtained from the climate environment information of the target city in step S1, and other parameters are obtained from the correlation coefficient table.

[0035] Furthermore, as described in step S4, the structural stability test of the building standard model of the target site is carried out by calculating the wind load and snow load. The specific rules of the structural stability test are as follows: the maximum wind pressure and maximum snow pressure of the target site are input into the computational fluid dynamics simulation system, the ultimate wind load and ultimate snow load are calculated, and the ultimate load is compared with the maximum pressure that the material can withstand. If the load is less than the maximum pressure that the material can withstand, it passes; otherwise, it fails. Among them, the maximum pressure that the material can withstand is based on the "Engineering Rock Classification Standard (GB / T50218-2014)", "Engineering Classification Standard of Soil (GB / T 50145-2007)", and "Wood Structure Design Standard (GB 50005-2017)";

[0036] Wind load and snow load calculation,

[0037] The wind load w k The calculation formula is w k =β z μ s μ z w0;

[0038] The snow load s k The calculation formula is s k =μ r s0;

[0039] Determine the comparison threshold of each material, among which the maximum pressure that wood can withstand is 4000kg / cm 2 The maximum pressure that stone can withstand is 10000kg / cm 2 The maximum pressure that soil can withstand is 100kg / cm 2 .

[0040] Furthermore, the seasonal and time-based indoor air circulation simulation and thermal comfort index calculation described in step S5 specifically include three thermal comfort simulation indices: temperature, relative humidity, and indoor wind speed in the two time periods of 3 pm to 5 pm and 6 am to 8 am in both winter and summer seasons.

[0041] Furthermore, the automatic matching of the “building element-building material” combination relationship that meets the thermal comfort standard through the building climate adaptability matching model in step S5 specifically includes the following steps:

[0042] Evaluate the thermal comfort level of each building and conduct a categorized evaluation of the thermal comfort level of each building in accordance with the Code for Design of Heating, Ventilation and Air Conditioning for Civil Buildings (GB50736-2012);

[0043] Determine the climate adaptability matching standards for each functional building;

[0044] Automatic inspection and result generation automatically detects the "building element-building material" pairing relationship that meets the thermal comfort standard and generates a set of preferred building schemes. The specific rules of the matching model are: under the simulation scenario and simulation indicators, if the building function is cultural and educational, and the assessed thermal comfort is level I or II, the building-material combination passes the inspection, otherwise the scheme is discarded; if the building function is commercial service, and the assessed thermal comfort is level I or II, the building-material combination passes the inspection, otherwise the scheme is discarded; if the building function is residential and livelihood, and the assessed thermal comfort is level I, the building-material combination passes the inspection, otherwise the scheme is discarded; finally, the schemes that pass the inspection are uniformly included in the set of preferred building schemes.

[0045] Furthermore, the model main body information and thermal comfort simulation results in step S6, the model main body information specifically includes site environment, building elements, and building materials, and the thermal comfort simulation results specifically include thermal comfort color grades.

[0046] The advantages of this method include combining a library of architectural design proposals for award-winning target sites with site climate information to construct a standard library compliant with the Building Information Modeling Application Standard (GB / T 19650). This provides a large number of simulated test samples for matching building materials by element, providing a foundation for subsequent intelligent detection and automatic matching of natural local materials. This approach not only integrates design concepts with regional climate characteristics but also lays a solid foundation for the sustainability and environmental adaptability of building projects.

[0047] By integrating structural stability and climate suitability into two key dimensions, the system automatically verifies and matches local materials to extreme climate environments, reducing the time required to match materials in architectural design projects from 14 days to 6 hours, significantly improving construction efficiency. This highly efficient matching system not only saves time but also ensures the stability and adaptability of selected materials under specific environmental conditions.

[0048] The combination relationship between different architectural elements and different building materials is taken into consideration, providing more possible architectural standard models for construction projects; and the inspection parameters and methods of different materials are taken into consideration, which is conducive to the diversity of the use of local materials in architectural schemes.
