[0028] Figure 1 1 is a method flow chart of a CIM-based design solution auxiliary review method provided by an embodiment of the present invention. Figure 1 As shown, an embodiment of the present invention provides a design scheme auxiliary review method based on CIM, the method comprising:

[0029] Step S10: Formulate city CIM data standards, and store the city CIM data standards in a preset standard library.

[0030] Specifically, in existing urban construction, when the government reviews the design plan of a construction project, it is usually necessary to first conduct a technical review by a professional planning unit or expert, and then the government will issue a formal review opinion. Only the plan that passes the review will eventually issue an engineering planning license. The CIM-based design plan auxiliary review method proposed in the present invention is to automatically review the BIM model based on GIS data + BIM data, obtain review records for reference by relevant personnel, reduce the review workload of reviewers, and in order to avoid the review results being invalid due to missing data, incorrect data, and errors in the uploaded BIM model data, preferably, a BIM model file standard is set. The formed BIM model file standard and the existing urban CIM data are organized into urban CIM data standards, which are used to standardize the information uploaded by users on the one hand, and provide design basis for designers on the other hand, and rely on the existing urban CIM data to carry out corresponding engineering design, reduce the probability of unqualified files appearing during the review process, and improve the review efficiency of the system.

[0031] Step S20: Obtain the BIM model of the design scheme submitted by the construction unit, verify the BIM model data according to preset rules, and store the BIM model that passes the verification in the BIM model library.

[0032] Specifically, the construction unit performs corresponding scheme design according to the urban 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 obtains the BIM model and transmits the BIM model to the processing unit 20. The processing unit 20 verifies the acquired BIM model data according to the urban CIM data standard stored in the storage unit 30 to determine whether the uploaded BIM model data is complete and whether the scheme meets the standard. If it is determined that the BIM model data uploaded by the construction unit fails the verification, an error message is output to the equipment end of the construction unit to remind the relevant personnel of the construction unit to confirm the file and re-upload it. If it is determined that the BIM model data uploaded by the construction unit passes the verification, the uploaded BIM model is stored in the BIM model library to facilitate file extraction and scheme review at a later stage.

[0033] Step S30: Automatically calculate the control index review of the BIM model that has passed the verification according to the preset project control rules to obtain the index review calculation results.

[0034] Step S301: Calculate the building setback index of the public space.

[0035] Specifically, building setback is the degree to which the building should be away from the planned land, that is, the boundary of the building shall not cross the building setback. When reviewing the BIM model data, it is also necessary to consider whether the building designed by the construction unit meets the prescribed building setback. It is necessary to ensure that the ground building model uploaded by the user is projected onto the outer contour of the building base, within the range of the building setback line; the building outline range is based on the outermost edge of the outer finished surface of the main body of the ground building and all components of the building. Building protrusions that are not allowed to protrude from the building setback line include: steps, platforms, window wells, ramps, flower beds, splashing, basement air inlets and outlets, underground buildings and building foundations, and other underground pipelines except those connected to the city pipelines within the base. The processing unit 20 compares the BIM model data uploaded by the user with the urban CIM data standard to determine whether there are building protrusions that cross the building setback line, and generates a judgment result.

[0036] Step S302: Calculate the building density index in the urban capacity.

[0037] Specifically, in the process of urban construction, the land use nature and the size of the soil block of each construction land are limited, that is, when carrying out urban construction, only the building type of the corresponding nature can be built in the designated plot. When the plot area is certain, there is a certain construction density beside the buildings built in the plot. For different application ranges, the density of the building will also be subject to different levels of requirements. For example, the building density of the building land with high fire protection requirements cannot be too large; the building density of the residential land must also meet certain living comfort requirements. Therefore, when reviewing the design plan, the design building density is also one of the necessary review items. The processing unit 20 obtains the BIM model to be reviewed, and calculates the building density of each plot of the design plan according to the building density calculation formula. The calculation formula is: building density = the sum of the building base areas of all buildings in the site / construction land area * 100%; wherein, before calculating the sum of the building base areas of all buildings in the site, it is necessary to calculate the base area of ​​each single building, and the calculation formula is: the base area of ​​the single building = the outer wall of the natural layer of the building that contacts the ground or the outer projection area of ​​the structure + the area of ​​the orthographic projection surface of the finished surface of the steps and ramps. The processing unit 20 obtains the calculation result of the building density index in the urban capacity according to the above formula.

[0038] Step S303: Calculate sunshine analysis index.

[0039] Specifically, urban buildings, especially urban residential buildings, have requirements for average daily sunshine hours. Residential buildings should meet the requirement that the sunshine hours within the effective sunshine time zone on the Great Cold Day should be no less than 2 hours cumulatively, and the cumulative minimum sunshine period should be no less than 30 minutes. Special activity buildings may have even higher sunshine requirements. For example, nurseries, children's activity rooms, and primary and secondary school dormitories should have full-window sunshine standards of no less than 3 hours on the winter solstice (with a cumulative minimum sunshine period of no less than 30 minutes); bedrooms, living rooms, hospitals, and half of the wards in nursing homes for the elderly and disabled, and classrooms in primary and secondary schools should be able to obtain a sunshine standard of no less than 2 hours on the winter solstice. There are many factors that affect sunshine time. Building height and building density may affect sunshine time. The processing unit 20 comprehensively sorts out the factors that affect sunshine time based on the city CIM data, and calculates the sunshine analysis index of the BIM model to be reviewed through the joint influence of multiple factors. The calculation rules are as follows: the sunshine analysis range is the positive projection range of the fan-shaped area formed by twice the effective projection height of the blocking building; the starting point of the building model sunshine time is the horizontal plane 0.9 meters above the window sill from the indoor floor.

[0040] Step S304: Calculate the scale of public services to be built.

[0041] Specifically, urban life cannot do without various public services, such as hospitals, schools, and fire stations. There are many functional areas in the city, namely high-density residential areas, low-density residential areas, office areas, commercial areas, and public service areas. The permanent populations in different areas are different. In order to meet people's various life needs in urban life, the total living demand in high-density residential areas is definitely higher than the total living demand in low-density residential areas. That is, whether it is educational resources or medical resources, the demand in high-density residential areas is higher. In order to meet different life needs, the number and scale of public services needed to be built need to be adjusted. For example, the number and scale of schools near high-density residential areas should be larger. When designing the construction of public services, requirements are often made for the building area and land area of ​​public service facilities according to the corresponding needs. The processing unit 20 calculates and analyzes the building area and land area of ​​the public service facilities according to the required information. The calculation rule is: if the planning conditions require the building area of ​​the public service facilities, the building area of ​​the public service facilities measured by the building model shall not be less than the area of ​​the public service facilities in the planning conditions; if the planning conditions require the land area of ​​the public service facilities, the orthographic projection area of ​​the area measured by the site model shall not be less than the area of ​​the public service facilities in the planning conditions. After completing the indicator calculation, the system automatically issues the indicator review results.

[0042] Step S305: Calculate the clear height index of the motor vehicle lane.

[0043] Specifically, when designing a motor vehicle lane, it cannot intersect with existing buildings when passing through urban buildings, so when reviewing the BIM model, it is necessary to review whether the road design complies with the rules. The processing unit 20 generates a box based on the BIM model data, using the surface formed by the setback line as the bottom and the road net height as the height for extension simulation. In the box extension path, no other components can be in the box. If other components are found to enter the box, it means that the road intersects with other buildings, and the design is wrong. In the extension simulation, it is necessary to focus on components that have a greater impact on the road, such as buildings and bridges.

[0044] Step S40: Execute multi-system model calculation of the verified qualified BIM model according to the preset calculation model to obtain the model calculation result.

[0045] Step S401: Estimating the population size.

[0046] Specifically, multiple systems provide multi-angle urban environment system auxiliary analysis, and the data obtained can not only be used to review the design plan, but also can further assist in the improvement of the urban design plan. One of them is about population estimation. Obtaining the estimated population value can determine whether the public facilities built meet the resource demand, and can also evaluate the convenience of user travel. It can not only be used to judge whether the existing design plan is reasonable, but also provide a certain modification reference for the design plan. According to the "Urban Residential Area Planning and Design Standard" GB50180-2018, the population value of the plot can be estimated according to the floor area ratio or building floors and area to assist the calculation of each system in the later stage. The processing unit 20 determines the number of building floors according to the BIM model, and extracts the corresponding indicator according to the number of floors: the maximum per capita residential land area, and estimates the population of the review area. The calculation formula is: regional population = building base area in the region × corresponding number of building floors ÷ maximum per capita residential land area.

[0047] Step S402: Perform regional visibility analysis.

[0048] Specifically, regional visibility reflects the rationality of urban design plans through sky visibility. Sky visibility is an indicator representing the visibility of the blue sky. It refers to the degree or visual range of the blue sky that can be seen without being blocked by clouds and haze in different weather conditions. This value can be used to reflect aspects such as the quality of urban space, the comfort level of public activities, and visual psychological expectations. Therefore, it can be used to assist in the design of urban visual corridors and to evaluate the rationality of urban design plans. Preferably, the equiangular projection method proposed by Stein in 1980 is used to process the projected image of the building into several concentric annual rings with equal spacing, and then all the annular parts are accumulated to represent the visible distance of the sky, and the sky visibility factor SVF is calculated. The calculation formula is:

[0049]

[0050] Where n is the total number of rings that divide the concentric circles; i is the serial number of the ring; a i Indicates the angular width of the sky within the i-th ring. Since the regional visibility value is strongly correlated with the geometric shape of urban buildings, when the value is too low, the system will automatically extract the location with a lower value for highlighting to assist the urban design plan in improving the urban spatial form.

[0051] Step S403: Perform street visibility analysis.

[0052] Specifically, the visibility of the building lines in the area is calculated by using street nodes, and the building lines with high exposure are evaluated. Street visibility can be used for the site selection of high exposure demand sites. When a building has a high exposure demand, the processing unit 20 determines whether the design scheme meets the requirements based on the street visibility analysis. The classification rules are: obtain the road node, set the visible distance at the node; at each node, draw a radial line of the corresponding distance until it touches the building line or is equal to the set distance value, and end the line segment; calculate how many line segments touch the building line; divide the number by the length of the building line, calculate the average value, and compare it with the building line in the area. The calculation formula is: building line visibility evaluation = total number of line segments touching the building line ÷ length of the building line. Since the street visibility value is strongly correlated with the urban street layout, when there is an excessively high value in the residential area (the visibility demand in the residential area is generally low, effectively protecting the privacy of residents), the system will automatically extract the location with a higher value for highlighting. Similarly, when a low value appears in a commercial area (visibility requirements in commercial areas are generally high to meet the exposure of street shops), the system will automatically extract the location with a low value for highlighting. This value can assist urban design plans in improving the urban layout.

[0053] Step S404: Perform traffic system calculation.

[0054] Specifically, the main calculations include the number of times vehicles are used, the total amount of greenhouse gas emissions, and sections of roads that may experience traffic congestion within the scope of the design. The calculation rules are as follows: the population age distribution data is obtained based on the statistical yearbook (the population age structure and dependency ratio in the population chapter); based on the population age distribution data, combined with the number of commuting trips and non-commuting trips in the "Main Results of Comprehensive Transportation Survey", the overall number of traffic trips for the design can be obtained. Combined with the travel mode structure ratio of each province and city in the survey form and the number of vehicles that can be carried, the number of times vehicles are used can be calculated. Since the possibility of road congestion is strongly correlated with the urban road network and population distribution, when there are excessively high values, the system will automatically extract the locations with higher values ​​for highlighting. It helps the reviewer quickly locate places where congestion may occur, and effectively alleviate traffic congestion by adding auxiliary facilities or adjusting the intensity of surrounding building development.

[0055] In a possible implementation plan, based on the "Main Results of the Fifth Comprehensive Transportation Survey in Shanghai", the transportation system is evaluated. Statistics show that the proportion of transportation travel structure is: walking 24.8%, rail transit 15.1%, ground bus 13.4%, large bus 3.8%, small car 19.2%, motorcycle 0.3%, non-motor vehicle 16.1%. The average number of daily trips per person: 1.12 times / person for non-commuting purposes, 1.04 times / person for commuting purposes. The number of people per vehicle: 1 person walking, 2480 people / train for rail transit, 50 people / car for ground bus, 50 people / car for large bus, 5 people / car for small car, and 1-2 people / car for non-motor vehicles. Therefore, in order to obtain the number of times a vehicle is used, the calculation formula is: the number of times a specific vehicle is used = total population × (trips for non-commuting purposes + trips for commuting purposes) × the proportion of the vehicle ÷ the number of people that the vehicle can carry. Statistics show that the average travel distance of residents in the city is 6.9 kilometers per time. Therefore, combined with the "Automobile Life Cycle Greenhouse Gas and Air Pollutant Emission Assessment Report", the amount of greenhouse gases that may be generated in the design plan can be obtained. The calculation formula is: Total greenhouse gas emissions = ∑ times a specific vehicle is used × average travel distance (km / time) × fuel consumption per 100 kilometers of the vehicle (liters / km) ÷ 100 × greenhouse gas emissions (kg / liter). Based on the above population estimation (based on the building volume ratio), the population of each building can be estimated. Therefore, the four-stage method of traffic demand forecasting commonly used in the transportation system (four-step method) can be used to roughly simulate the traffic travel trajectory in this plan. This data can be used to observe sections of the road where traffic jams may occur. The calculation logic is as follows: based on the land use attributes of the design plan, residential areas are selected, and based on the population size and age structure, corresponding populations are attached to the residential areas; residential areas are connected with business office areas, commercial service areas, medical and health land, primary and secondary schools, and complex service facility land to find the shortest path between residential areas and corresponding functional areas; the number of overlaps of each road is recorded, and the overlap amount of the global road network is calculated; if the value is high, it is determined that in the absence of an external road network, the road is more likely to experience traffic congestion.

[0056] Step S405: Perform energy system calculation.

[0057] Specifically, the demand for electricity in cities is very large, so the energy system calculation is mainly for the calculation of electricity demand. According to the description of power engineering in municipal facilities in Chapter 7 of the "Shenzhen Urban Planning Standards and Guidelines", different unit building area load prediction indicators can be selected according to the land use attributes of the building area. The calculation formula is: total electricity consumption in the region = ∑ building base area × corresponding building floor × unit area load prediction indicator. Since the overall electricity consumption of the city is strongly correlated with the planned population of the city, when there is an excessively high value, the system will compare it with the power generation of existing / planned energy facilities to determine whether the existing energy facilities can support the planned population, so as to help the reviewer evaluate the feasibility of the urban design plan in the energy distribution system. At the same time, the model can calculate the location that requires high energy consumption through building volume calculation, which effectively helps the reviewer to deploy energy auxiliary measures for the location during the planning stage.

[0058] Step S406: Perform water system calculation.

[0059] Specifically, the water demand and sewage output are mainly calculated. According to the specific description of water supply projects in Chapter 7 of the "Shenzhen Urban Planning Standards and Criteria" Municipal Facilities, based on the permanent population, the comprehensive water consumption index per unit population should be 0.4m3 / person·day-1.0 cubic meters / person·day. Sewage output: According to the specific description of drainage projects in Chapter 7 of the "Shenzhen Urban Planning Standards and Criteria" Municipal Facilities, the amount of domestic sewage is 90% of the average daily water consumption. The calculation formula for daily water demand in the region is: daily water demand in the region = the corresponding population in the region × comprehensive water consumption index per unit population. The calculation formula for domestic sewage generation in the region is: domestic sewage generation in the region = water demand in the region × 90%. Since the overall water consumption and sewage discharge of the city are strongly correlated with the planned population of the city, when there is an excessively high value, the system will compare it with the output of the existing / planned water plant or the treatment capacity of the sewage treatment plant to determine whether the existing facilities can support the planned population, so as to help the reviewer evaluate the feasibility of the urban design plan in the water supply and drainage system. At the same time, the model can calculate the pipe network sections that need to increase the diameter of the water pipes through building volume calculations, effectively helping the reviewer to deploy auxiliary measures for the location during the planning stage.

[0060] Step S407: Perform solid waste system calculations.

[0061] Specifically, the amount of domestic waste generated is mainly calculated. According to the specific description of environmental sanitation (garbage) in the municipal facilities in Chapter 7 of the "Shenzhen Urban Planning Standards and Guidelines", the amount of domestic waste generated is calculated based on 1.0 kg to 1.5 kg of domestic waste generated per person per day. Therefore, by multiplying this data by the population, the approximate amount of domestic waste generated in the residential area can be obtained. The calculation formula is: Domestic waste generation = daily domestic waste production per capita × population. Since the amount of urban domestic waste generated is strongly correlated with the planned population of the city, when there is an excessively high value, the system will compare it with the processing capacity of the existing / planned waste treatment plant to determine whether the existing facilities can support the planned population, so as to help the reviewer evaluate the feasibility of the urban design plan in domestic waste treatment and the formulation of garbage collection routes. At the same time, the model can select the location where garbage trucks need to be collected through building volume calculation, or effectively average the carrying pressure of garbage trucks by adjusting the building volume.

[0062] Step S50: Linkingly displaying the indicator review calculation results and the model calculation results.

[0063] Specifically, in order to facilitate the reviewers to obtain the calculation results intuitively, it is preferred to set a human-computer interaction unit 40, display the generated various index review calculation results and model calculation result display buttons through the display module 402, and then passively trigger the display of various index review calculation results and model calculation results through the input module 401. For example, click on the scale indicator of the public service to display all the public service facilities and identification symbols on the GIS map, and click on different public service types through the input module 401 to highlight and display the symbols and scale information boxes. Click on the sunshine index to display the sunshine analysis results of all building units on the GIS map, and click on the building unit to display the sunshine analysis results of the building unit on the GIS map. Click on the motor vehicle to the clear height, the current road will be highlighted in the GIS, and the rest will be transparent. The viewing angle is positioned at the part that collides with the clear height box and is marked with a red breathing mark.

[0064] In an embodiment of the present invention, the system helps users to review design plans more intuitively through a three-dimensional display of the entire BIM model of the city, a textual display of the calculation results of management and control indicators, and a linked display of indicators and models, as well as auxiliary review and analysis tools such as sky exposure analysis, street visibility analysis, traffic congestion analysis, energy demand calculation, water supply and drainage calculation, and solid waste generation calculation in the city dimension.
