Fig. 1 is a flowchart of a method for a CIM-based design solution aided review method according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a design solution aided review method based on CIM, where the method includes:
step S10: and formulating an urban CIM data standard, and storing the urban CIM data standard into a preset standard library.
Specifically, in the existing city construction, when the government examines the design scheme of the construction project, a professional planner or expert usually needs to perform technical examination, and then the government issues a formal examination opinion, and finally the approved scheme will issue an engineering planning license. The design scheme auxiliary examination method based on CIM provided by the invention is characterized in that the BIM is automatically examined based on GIS data and BIM data, the examination records are obtained and are referred by related personnel, the examination workload of examiners is reduced, and the examination result invalidity caused by data loss, data error and file error of uploaded BIM data of a designer is avoided. The formed BIM model file standard and the existing city CIM data are arranged into a city CIM data standard, on one hand, the BIM model file standard is used for standardizing data uploaded by a user, on the other hand, design basis is provided for a designer, corresponding engineering design is carried out by depending on the existing city CIM data, the probability of unqualified files in the process of examination is reduced, and the examination efficiency of the system is improved.
Step S20: and acquiring a design scheme BIM model submitted by a construction unit, checking data of the BIM model according to a preset rule, and storing the BIM model qualified in checking in a BIM model library.
Specifically, the construction unit performs corresponding scheme design according to the city CIM data standard issued by the reviewer, after the design is completed, the design scheme BIM model is uploaded through the preset port, the acquisition unit 10 acquires the BIM model and transmits the BIM model to the processing unit 20, the processing unit 20 performs data verification on the acquired BIM model according to the city CIM data standard stored in the storage unit 30, and whether uploaded BIM model data are complete or not is judged, and whether the scheme meets the standard or not is judged. And if the BIM model data uploaded by the construction unit is judged to be unqualified in verification, outputting error information to the construction unit equipment end, and reminding relevant personnel of the construction unit to confirm and upload the file again. And if the BIM model data uploaded by the construction unit is judged to be qualified in verification, the uploaded BIM model is stored and enters a BIM model library, so that file extraction and scheme verification can be conveniently carried out in the later period.
Step S30: and executing the automatic management and control index audit calculation of the BIM which is qualified in verification according to the preset project management and control rule, and obtaining the index audit calculation result.
Step S301: and calculating the building bound-quitting index of the public space.
Specifically, the building back bound is the degree to which the specified building should be from the planned site, i.e., the boundary of the building must not cross the building back bound. When checking the BIM model data, it is also necessary to consider whether or not the building designed by the construction organization meets a predetermined building bound. The method includes the steps that a user uploads a BIM model on-ground building model to be orthographically projected to the outer contour of a building base within a limit deviation range of a building; the building outline range is based on the outer most edge of the outer complete surface of all the components of the ground building main body and the building. Architectural protrusions that do not allow for protruding architectural boundaries include: steps, platforms, window shafts, ramps, flower beds, water distribution, air inlets and outlets of basements, underground buildings and building foundations, and other underground pipelines except urban pipelines connected in the base. The processing unit 20 compares the BIM model data uploaded by the user with the city CIM data standard, determines whether building protrusions crossing the building delimitation exist, and generates an interpretation result.
Step S302: and calculating the building density index in the urban capacity.
Specifically, in the process of city construction, the land use property and the soil block size of each construction land are limited, namely, during city construction, building types with corresponding properties can only be set in the defined land blocks. When the area of the land is fixed, the building edge built in the land has certain building density, and for different application ranges, the density of the building can be subjected to different levels of requirements, for example, the building land with high fireproof requirement cannot be overlarge; the building density of residential sites also meets certain residential comfort requirements. The density of the designed building is one of the items that must be reviewed when the design is reviewed. The processing unit 20 obtains the to-be-examined BIM model, and calculates the building density of each plot of the design scheme according to a building density calculation formula, wherein the calculation formula is as follows: the building density is the sum of the base area of all buildings in the site/the area of the construction land by 100 percent; before calculating the sum of the base areas of all buildings in the site, the base area of each single building needs to be calculated, and the calculation formula is as follows: the base area of the single building is equal to the orthographic projection area of the outer wall or the peripheral orthographic projection area of the structure of the natural-layer building contacting the ground plus the orthographic projection area of the step and ramp finishing surface. The processing unit 20 obtains the calculation result of the building density index in the urban capacity according to the formula.
Step S303: and (5) calculating sunshine analysis indexes.
Specifically, the urban building, especially the urban residential building, has requirements on the daily average sunshine duration, and the residential building should meet the requirement that the sunshine duration in the effective sunshine duration zone of the severe cold day is not less than 2 hours, and the accumulative minimum sunshine duration is not less than 30 minutes. The possible sunshine requirement standard of special movable buildings is higher, for example, the standard of full-window sunshine in nursery houses, infant movable rooms and dormitories of primary and secondary schools is not less than 3 hours in winter solstice, (the accumulated minimum sunshine time period is not less than 30 minutes); the standard of sunshine of not less than 2 hours in winter solstice can be obtained in the wards of old people residence, the bedroom of disabled people residence, the living room, the hospital, the nursing home and the classrooms of middle and primary schools. The factors influencing the sunshine duration are many, the building height and the building density can influence the sunshine duration, the processing unit 20 comprehensively arranges the factors influencing the sunshine duration according to the urban CIM data, the calculation of the sunshine analysis indexes of the BIM model to be examined is carried out through the common influence of a plurality of factors, and the calculation rule is as follows: the sunshine analysis range is a sector area orthographic projection range formed by shielding 2 times of the effective projection height of the building; the starting point of the sunshine time of the building model is a horizontal plane with the distance between the windowsill and the indoor terrace being 0.9 m.
Step S304: and calculating the scale of the configured public service.
Specifically, various public services such as hospitals, schools, fire stations and the like can not be distributed in urban life, the city has a plurality of functional areas, namely a high-density residential area, a low-density residential area, an office area, a business area and a public service area, the population of different areas is different, and in order to solve various living needs of people in urban life, the total living demand of the high-density residential area is certainly higher than that of the low-density residential area, namely, the demand of the high-density residential area is higher no matter educational resources and medical resources are provided. To address different living needs, the number and size of the required public services to be deployed need to be adjusted, for example, the number and size of schools near high density residential areas should be larger. When public service design is configured, requirements are often provided for the building area and the land area of the public service facility according to corresponding requirements, the processing unit 20 respectively performs calculation and analysis on the building area and the land area of the public service facility according to the requirement information, and the calculation rule is as follows: if the planning condition puts forward a requirement on the building area of the public service facilities, the building area of the public service facilities measured by the building model is not smaller than the area of the public service facilities in the planning condition; and if the planning condition puts forward a requirement on the land area of the public service facility, the orthographic projection area of the area measured by the site model is not less than the area of the public service facility in the planning condition. And after the index calculation is finished, the system automatically issues an index examination result.
Step S305: and calculating the clear height index of the motor lane.
Specifically, when a motor vehicle lane is designed, the motor vehicle lane cannot intersect with an existing building when passing through an urban building, so that the BIM model examination is performed to examine whether the road design meets the rules. The processing unit 20 performs an extension simulation based on the BIM model data, using a plane formed by the delimitation line as a bottom and the road clear height as a height generation box, and if it is found that other members cannot be in the box extension path, it indicates that the road intersects with other buildings, and a design error occurs.
Step S40: and executing multi-system model calculation of the BIM which is qualified in verification according to a preset calculation model to obtain a model calculation result.
Step S401: population estimates are made.
Specifically, the multi-system provides multi-angle city environment system auxiliary analysis, and the obtained data can be used for examining the design scheme and further assisting the improvement of the city design scheme. One of the measures is the estimation of the population quantity, and the estimation value of the population quantity can be obtained to judge whether the allocated public facilities meet the resource requirements or not and also evaluate the travel convenience of the user. The method can be used for judging whether the existing design scheme is reasonable or not, and can also provide certain modification reference for the design scheme. According to the urban residential area planning and design standard GB50180-2018, the population value of the belonged plot can be estimated according to the volume ratio or the building floor and area so as to assist later-stage system calculation. The processing unit 20 judges the number of floors of the building according to the BIM model, and extracts corresponding indexes according to the number of floors: estimating the population quantity of the examination area by the maximum residential area per capita, wherein the calculation formula is as follows: the number of regional population is the maximum of the area of a building base in the region multiplied by the number of corresponding building floors divided by the floor area for per-person residential buildings.
Step S402: area visibility analysis was performed.
Specifically, the reasonability of city design schemes is reflected by the visibility of the sky in the region, the visibility of the sky is an index representing the visibility of the blue sky, and the degree or the view range of the blue sky can be seen without being shielded by cloud layers and haze in different weathers. The numerical value can be used for reflecting the aspects of urban space quality, public activity comfort degree, visual psychological expectation and the like, so that the numerical value can be used for assisting the design of an urban visual corridor and evaluating the reasonability of an urban design scheme. Preferably, the equiangular projection method proposed by steine in 1980 is adopted to process the projection image of the building into a plurality of concentric annual rings with equal intervals, and then the sky visible factor SVF is calculated by accumulating all the annular parts to represent the visible distance of the sky, wherein the calculation formula is as follows:
wherein n is the total number of the rings dividing the concentric circles; i is the serial number of the ring; a isiIndicating the angular width of the sky within the ith circle. Because the region visibility numerical value has strong relevance with the geometric shape of the urban building, when the numerical value is too low, the system can automatically extract the zone bit with lower numerical value to highlight so as to assist the improvement of the urban design scheme on the urban space form.
Step S403: street visibility analysis was performed.
Specifically, the visibility of the building lines in the area is calculated by utilizing the street nodes, and the building lines with high exposure are evaluated. The street visibility can be used for site selection of a high exposure demand site, and when a building has a high exposure demand, the processing unit 20 determines whether the design scheme meets the requirements according to the street visibility analysis. The classification rule is as follows: obtaining road nodes, and setting visible distances at the nodes; drawing the radioactive rays of the corresponding distance at each node until the radioactive rays touch the line along the building or are equal to the set distance value, and finishing the line segment; calculating how many line segments the building is contacted by along the line; this number is divided by the length of the building along the line and averaged for comparison with the building along the area. The calculation formula is as follows: building line visibility assessment is the total number of line segments touching the building line divided by the building line length. Because the visible numerical value of street has strong relevance with city street configuration form, consequently when too high numerical value appears in the place of living in district usefulness (the visible demand of living in district is generally lower, effectively protects resident privacy), the system can draw out the higher position of numerical value automatically and highlight. Similarly, when too low a value occurs in the business district (the visibility requirement of the business district is generally high to satisfy the street shop exposure), the system will automatically extract the lower value zone to highlight. By the numerical value, the improvement of the city arrangement form of the city design scheme can be assisted.
Step S404: and carrying out traffic system calculation.
Specifically, the times of using the vehicles, the total amount of released greenhouse gases and the road sections where traffic jam may occur within the scope of the design scheme are mainly calculated. The calculation rule is as follows: obtaining population age distribution data according to a statistical yearbook (population age structure and fostering ratio in a population section); based on population age distribution data, the total number of commuting trips of the design scheme can be obtained by combining the number of commuting trips and the number of non-commuting trips in the comprehensive traffic survey main achievement. The use times of the transportation means can be calculated by combining the structure ratio of the travel modes of provinces and cities in the questionnaire and the carrying number of the transportation means. Since the possibility of road congestion has strong correlation with urban road networks and population distribution, when an excessively high numerical value occurs, the system can automatically extract a zone with a higher numerical value to highlight the zone. The method helps the examiner to quickly locate the place where the traffic jam is likely to occur, and effectively relieves the traffic jam condition by adding auxiliary facilities or adjusting the development intensity of surrounding buildings.
In a possible implementation scheme, the traffic system evaluation is carried out based on the 'Shanghai fifth comprehensive traffic survey main result', statistics show that the traffic travel structure accounts for: 24.8% of walking, 15.1% of rail traffic, 13.4% of ground public transport, 3.8% of motor bus, 19.2% of passenger car, 0.3% of motorcycle and 16.1% of non-motor vehicle. Average daily trip times: non-commuting purpose 1.12 times/person, commuting purpose 1.04 times/person. The number of the load people per car: 1 person walking, 2480 persons/train on rail, 50 persons/train on the ground, 50 persons/train on a bus, 5 persons/train on a bus, and 1-2 persons/train on a non-motor vehicle. Therefore, to find the number of times the vehicle is used, the calculation formula is: the number of times a particular vehicle is used is the total population x (non-commuting trip + commuting trip) x the vehicle ratio ÷ the number of people the vehicle can carry. Statistics shows that the average travel distance of residents in the whole city is 6.9 km/time, so that the greenhouse gas quantity possibly generated in the design scheme can be obtained by combining an evaluation report of greenhouse gas and atmospheric pollutant emission in the life cycle of an automobile. The calculation formula is as follows: total greenhouse gas emissions ═ Σ number of times of use of a specific vehicle × average travel distance (km/time) × oil consumption per hundred kilometers of the vehicle (liter/km) ÷ 100 × greenhouse gas emissions (kg/liter). Based on the population estimation (based on the building volume ratio), the population of each building can be estimated, so that the traffic travel track in the scheme can be approximately simulated by using a traffic demand forecasting four-stage method (four-step method) commonly used in a traffic system. This data can be used to observe road segments where traffic congestion is likely to occur. The calculation logic is: selecting a residential area based on the land property of the design scheme, and attaching a corresponding population to the residential area based on population scale and population age structure; connecting the residential area with a business office area, a business service area, a medical and health land, a middle and primary school and a composite service facility land, and searching for the shortest path between the residential area and the corresponding functional area; recording the stacking times of each road, and measuring and calculating the stacking amount of the global road network; and if the numerical value is higher, the possibility that the road is congested is higher under the condition that no external circuit network exists.
Step S405: and performing energy system calculation.
Specifically, the urban power consumption requirement is very large, so the energy system calculation is mainly carried out for calculating the power consumption requirement, and according to the Shenzhen urban planning standard and criterion and the description in the power engineering in the municipal facilities in the seventh section, the load prediction indexes of different unit building areas can be selected according to the land property of the building areas. The calculation formula is as follows: the total electricity consumption in a region is ∑ building base area × corresponding building floor × unit area load prediction index. Since the total electricity consumption of a city is strongly correlated with the population of the city plan, when an excessively high value occurs, the system compares the electricity generation amount of the existing/planned energy facility to determine whether the existing energy facility can support the population of the city plan, thereby helping a censorship to evaluate the feasibility of the city design scheme on the energy distribution system. Meanwhile, the model can calculate the area needing high energy consumption through building size calculation, and effectively helps a censorship party to deploy energy auxiliary measures for the area in a planning stage.
Step S406: and (5) performing water system calculation.
Specifically, the water demand and the sewage output are mainly calculated, according to the Shenzhen City planning Standard and guidelines, and the concrete description of the water supply engineering in the seventh section of municipal facilities, based on the population of the permanent residence, the comprehensive water consumption index of the unit population is preferably 0.4m3-1.0 cubic meter per person day. Sewage output: according to the urban planning standards and guidelines of Shenzhen city, the concrete description of drainage engineering in the seventh section of municipal facilities, the bioactive sewage is 90% of the average daily water consumption. The calculation formula of daily water demand in the area is as follows: the daily water demand in the region is equal to the corresponding population quantity multiplied by the comprehensive water consumption index of unit population in the region. The calculation formula of the yield of the regional endogenous active sewage is as follows: the yield of the active sewage in the region is equal to the water demand in the region multiplied by 90 percent. Because the total water consumption and the discharge capacity of the city are strongly correlated with the urban planning population, when an overhigh numerical value appears, the system can be compared with the output of the existing/planned tap water plant or the treatment capacity of the sewage treatment plant to determine the existing situationWhether facilities can support the planning population or not helps the examiner to evaluate the feasibility of the urban design scheme on the water supply and drainage system. Meanwhile, the model can calculate the pipe network road section needing to increase the pipe diameter of the water pipe through building volume calculation, and effectively helps an examiner to deploy auxiliary measures for the region in a planning stage.
Step S407: and (5) performing solid waste system calculation.
Specifically, the domestic waste production amount is mainly calculated according to the specific description of environmental sanitation (garbage) in municipal facilities in the seventh section of Shenzhen city urban planning standards and guidelines, and is calculated according to the daily domestic waste production amount of 1.0 kg-1.5 kg per person. Therefore, the data is multiplied by the population number to obtain the approximate yield of the domestic garbage in the residential area. The calculation formula is as follows: the domestic waste yield is equal to the daily domestic waste yield multiplied by the population number of people. Because the urban domestic garbage production quantity has strong relevance with the urban planning population quantity, when an overhigh numerical value appears, the system can compare with the treatment quantity of the existing/planning garbage disposal plant station to determine whether the existing facilities can support the planning population, thereby helping a reviewer to evaluate the feasibility of the urban design scheme in the domestic garbage disposal and draw up a garbage collection route. Meanwhile, the model can select areas needing to be added with garbage truck collection through building size calculation, or effectively average the garbage truck carrying pressure through adjusting the building size.
Step S50: and displaying the index examination calculation result and the model calculation result in a linkage manner.
Specifically, in order to facilitate the examiner to visually acquire the calculation result, it is preferable that the human-computer interaction unit 40 is configured to display each generated index examination calculation result and model calculation result display button through the display module 402, and then passively trigger to display each index examination calculation result and model calculation result through the input module 401. For example, the index of the scale of the public service is clicked to be configured, all the configured public service facilities and identification symbols are displayed on a GIS map, different public service types are clicked through the input module 401, and the symbols and the scale information frame are highlighted and displayed. And clicking the sunshine index, displaying the sunshine analysis results of all the single buildings on the GIS map, clicking the single buildings, and displaying the sunshine analysis results of the single buildings on the GIS map. When the motor vehicle is clicked to reach the clear height, the current road can be highlighted in the GIS, the rest is transparent, the visual angle is positioned at the part where the motor vehicle collides with the clear height box, and the motor vehicle is marked by red breathing.
