[0021] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0022] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0023] Based on this, the embodiment of the present invention provides a method for preparing a sponge city construction map, referring to Figure 1 , Figure 1 The present invention is a schematic flow chart of a first embodiment of a method for preparing a sponge city construction map.

[0024] In this embodiment, the method for preparing the sponge city construction map includes: Step S10: Obtain the approval drawings of the sponge city project.

[0025] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a terminal device, etc. capable of realizing the above functions. The following takes the terminal device as an example to illustrate this embodiment and the following embodiments.

[0026] It should be noted that sponge city is an urban design concept that aims to effectively manage and utilize urban rainfall and enhance the city's adaptability to climate change through the combination of urban infrastructure and natural systems. The construction of sponge cities not only helps to reduce urban waterlogging and improve the urban water environment, but also promotes biodiversity and urban ecological balance. Therefore, sponge city construction has become one of the important directions for sustainable urban development.

[0027] The approval drawings of the sponge city project are not simple topographic, zoning and structural diagrams of various facilities, but project drawings with corresponding annotation information for each type of layer, wherein each layer corresponds to a plot, zone, underlying surface and sponge facility. The annotation information includes but is not limited to the runoff coefficient, effective depth, pollution removal rate, elevation of the low point corresponding to the service area, inlet elevation, facility bottom elevation and overflow elevation, etc., depending on the type of layer. This embodiment does not impose specific restrictions on this.

[0028] The drawings submitted for review refer to CAD drawings, Word document tabular drawings and other types of drawings provided by the design unit. Due to the data isolation of drawings in different formats during review, effective data sharing cannot be carried out, and for some complex facilities, the cost cannot be accurately calculated.

[0029] The parameters that need to be reviewed for the drawings submitted for review include but are not limited to the designed annual runoff volume control rate, annual runoff pollution control rate, hard surface rate, guest water treatment index, vertical rationality index, facility selection information, allocation ratio of various facilities, evaluation index of uniform distribution of various facilities, rainwater local treatment index, input-output ratio and cost range. The above index data can be used to evaluate the sponge city project designed by the design unit, and then determine whether it meets the local sponge city planning requirements.

[0030] Step S20: Standardizing the submitted drawings according to a preset standard mapping strategy to obtain standard city construction drawings.

[0031] The preset standard mapping strategy refers to setting the coordinate system, layer name specifications, layer mapping requirements, and annotation requirements, so as to structure the unstructured data, establish a facility ledger, lay the foundation for the information management of the sponge facility life cycle, and allow the data to play its value in the evaluation and operation and maintenance management stages.

[0032] The traditional review is that designers convert the design parameters in the drawings into a standardized calculation book. It is difficult to match the parameters in the drawings with those in the calculation book, and there may be calculation errors or cheating. Standardizing the initial urban construction drawings based on preset standard mapping strategies can eliminate this situation. The parameters are identified from the graphics and annotations of the drawings. The drawings can visually magnify the existing problems, and the chances of errors and cheating will be much smaller. In addition, during on-site verification, the drawings can be used to better verify the existence of facilities, whether the scale is consistent, and whether there are errors in the parameters.

[0033] Furthermore, the drawings submitted for examination shall at least include: graphics and annotation information of the plot, subdivision, underlying surface and sponge facilities; The standardization of the submitted drawings according to the preset standard mapping strategy to obtain standard urban construction drawings includes: Determine the various plots, zones, underlying surfaces, sponge facilities and marking specifications in the drawings submitted for review, and extract the parameters to be reviewed in the drawings submitted for review; Generate target layers of corresponding categories according to the graphics of various plots, partitions, underlying surfaces and sponge facilities; Annotate each target layer according to the annotation specification and the parameters to be reviewed; Integrate the labeled target layers to obtain a standard urban construction map.

[0034] In the specific implementation, refer to Figure 2 The plot contains two layers: graphics and text. The partition contains first-level partition, second-level partition, first-level partition annotation, and second-level partition annotation layer. The partition name is marked. The underlying surface is divided into many categories. Each type is a layer. Each type of underlying surface corresponds to a annotation layer to place annotation information, marking the runoff coefficient and its value. The facilities are also divided into many categories. Each type is a layer. Each type of facility corresponds to a annotation layer to place annotation information, marking the effective depth and its value, the pollution removal rate and its value, the service area corresponding to the low point elevation and its value, the inlet elevation and its value, the facility bottom elevation and its value, and the overflow elevation and its value. The layer can be generated by importing a .las file. All graphics are closed polylines and cannot be hollow polygons to prevent misjudgment.

[0035] Step S30: Conducting a rationality review on the standard urban construction map, wherein the rationality review includes an output benefit review, an environmental benefit review, and an economic benefit review.

[0036] It should be noted that the preparation of sponge city construction maps refers to labeling each layer based on the annotation information of each layer, so that more accurate project data can be provided in the subsequent review stage, and the calculation of annual runoff control rate and cost can be more efficient.

[0037] Furthermore, in this embodiment, the produced target sponge city construction drawings can also be modified to eliminate errors, omissions or areas that need to be modified in the process of producing standard drawings, thereby improving the accuracy of the drawings.

[0038] Specifically, when modifying the target sponge city construction drawings, the modifications can be made online, and the historical versions of the drawings can be managed online to achieve data sharing and avoid data loss. Figure 3 , Figure 3This is a schematic diagram of an example of the online drawing operation interface in this embodiment. Modify the drawings that need to be modified, such as moving, scaling, and rotating drawings that do not have a unified coordinate system, placing graphic objects on the correct layers, modifying graphic and annotation information according to the drawing format, closing unclosed polylines, dividing hollow polylines, adding, deleting, and modifying layers, graphic objects, and annotations, so that the elements that need to be reviewed are correctly displayed in the drawings, thereby improving the efficiency of subsequent reviews.

[0039] Step S40: Generate the overall project review result according to the output benefit review result, the environmental benefit review result and the economic benefit review result.

[0040] Step S50: When the overall review result of the project is passed, the target sponge city construction map is output It should be noted that the rationality review of standard urban construction drawings refers to the review of standard urban construction drawings in four dimensions, namely, output benefit review, environmental benefit review, economic benefit review and project overall review. Referring to Table 1, the review indicators of these four dimensions include but are not limited to annual runoff total control rate, annual runoff pollution control rate, hard ground rate, guest water treatment index, vertical rationality index, facility selection information, allocation ratio of various facilities, evaluation index of uniform distribution of various facilities, rainwater nearby treatment index, input-output ratio, cost range and project overall evaluation results.

[0041] Table 1

[0042] This embodiment obtains several initial urban construction drawings and drawing review parameters in advance, and then standardizes the drawings submitted for review according to a pre-set standard drawing strategy, so that the data in the drawings submitted for review are converted into structured data to obtain standard urban construction drawings. Finally, by conducting a rationality review of the standard urban construction drawings in multiple dimensions, the rationality of the sponge city project is improved, avoiding the technical problem of non-standard sponge city construction drawings in the prior art, which leads to low efficiency in project identification and review.

[0043] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 4 , step S30, comprising: Step S301: extracting drawing review parameters from the submitted drawings.

[0044] Step S302: Based on the drawing review parameters and the set sponge city planning information, determine the annual runoff volume control rate, annual runoff pollution control rate, hard ground rate, guest water treatment index and vertical rationality index.

[0045] Step S303: conducting an output benefit review based on the annual runoff volume control rate, annual runoff pollution control rate, hard surface rate, guest water treatment index, and vertical rationality index to obtain an output benefit review result.

[0046] It should be noted that the drawing review parameters refer to the basic attributes of various plots, divisions, underlying surfaces and sponge facilities in the submitted drawings, such as area, runoff coefficient, size, length and other information. Since the area, runoff coefficient, size, length and other information in the submitted drawings from different sources may have inconsistencies in unit formats, in order to improve the review accuracy during the subsequent output benefit review, environmental benefit review and economic benefit review, the drawing review parameters in the submitted drawings can be extracted to calculate indicators such as annual runoff total control rate, annual runoff pollution control rate, hard ground rate, guest water disposal index and vertical rationality.

[0047] In specific implementation, output benefits refer to encouraging projects with conditions to complete more rainwater and pollutant control, reduce hard surfaces, effectively handle guest water from sister projects, and vertically ensure that rainwater can be collected and stored, and the benefit indicators of rainwater exceeding the standard can be discharged.

[0048] Among them, the annual runoff total volume control rate refers to encouraging qualified projects to complete more rainwater control. The more completed, the higher the evaluation level. By comparing the designed annual runoff total volume control rate with the target annual runoff total volume control rate, the excellent, medium and poor levels of the annual runoff total volume control rate indicator can be evaluated.

[0049] The target annual runoff control rate is the project target specified during sponge city planning; the design annual runoff control rate is the design rainfall corresponding to the design storage capacity obtained by converting the annual runoff control rate and the design rainfall.

[0050] Specifically, refer to Figure 5 , Figure 5 This is a schematic diagram of the evaluation process of the total annual runoff control rate in this embodiment. The relationship between the total annual runoff control rate and the design rainfall is provided by the sponge city planning of each city; the design rainfall H (mm) corresponding to the design storage capacity is obtained by the comprehensive runoff coefficient φ (dimensionless), the design storage capacity V (m3), and the project area m2 through V=HφF; the comprehensive runoff coefficient is obtained by weighting the runoff coefficients of different underlying surfaces of the project by area; the design storage capacity is obtained by adding up the areas of different facilities × effective depths; the area is obtained by adding up different underlying surfaces; the underlying surface and facility parameters are identified in the construction drawings.

[0051] The annual runoff pollution control rate means that projects with conditions are encouraged to complete more pollutant control. The more completed, the higher the evaluation level. By comparing the designed annual runoff pollution control rate and the target annual runoff pollution control rate, the excellent, medium and poor levels of the annual runoff pollution control rate indicator are evaluated.

[0052] Among them, reference Figure 6 , Figure 6 This is a schematic diagram of the mid-term runoff pollution control rate evaluation process in this embodiment. The target annual runoff pollution control rate is the project target specified in the sponge city planning. The design annual runoff pollution control rate is calculated in the previous step and multiplied by the design comprehensive pollution removal rate. The design comprehensive pollution removal rate is obtained by weighting the pollution removal rates of different facilities by the service area. The facility parameters are identified in the construction drawing.

[0053] The hard ground rate means that projects are encouraged to reduce hard ground. For plots with relatively high hardening rates, green roofs and permeable paving facilities can be used to reduce hard ground. By comparing the hard ground rate of the designed scheme and the target hard ground rate, the excellent, medium and poor grades of the hard ground rate index are evaluated.

[0054] The target hard ground rate is the project target specified in the sponge city planning, and the design hard ground rate is the hard ground in the underlying surface type divided by the total area of ​​the underlying surface; the underlying surface parameters are identified from the construction drawings.

[0055] The guest water treatment index refers to encouraging qualified projects to effectively treat guest water from sister projects. By comparing the designed guest water volume and the target storage volume, the excellent, medium and poor levels of the guest water treatment index are evaluated.

[0056] Among them, reference Figure 7 , Figure 7 Schematic diagram of the evaluation process of guest water treatment indicators in this embodiment. The designed guest water volume is declared by the plan and is generally a fixed value; the target storage volume V (m3) is obtained by V=HφF through the underlying surface runoff coefficient φ (dimensionless), the designed rainfall H (mm), and the underlying surface area F (m2); the underlying surface runoff coefficient is obtained by weighting the runoff coefficients of different underlying surfaces of the project by area; the underlying surface area is obtained by adding different underlying surfaces; the designed rainfall H (mm) is obtained by the target annual runoff control rate from the relationship between the annual runoff control rate and the designed rainfall; the relationship between the annual runoff control rate and the designed rainfall is provided by the sponge city planning of each city; the target annual runoff control rate is the project target specified in the sponge city planning; the underlying surface parameters are identified in the construction drawing.

[0057] The vertical rationality index refers to the vertical direction of the project facilities to ensure that rainwater can be collected and stored, and that excess rainwater can be discharged. The system judgment logic is that the elevation of the lowest point of the service area ≥ the elevation of the inlet ≥ the elevation of the overflow ≥ the elevation of the bottom of the facility + the effective depth. The facility elevation is identified in the drawings. If all the facility elevations are reasonable, the project vertical direction is reasonable, otherwise there is irrationality.

[0058] Furthermore, the rationality review of the standard urban construction map also includes: Based on the drawing review parameters and sponge city planning information, determine the facility selection information, the allocation ratio of various facilities, the evaluation index of the uniform distribution of various facilities, and the index of nearby rainwater treatment; An environmental benefit review is conducted based on facility selection information, allocation ratios of various types of facilities, evaluation indicators for uniform distribution of various types of facilities, and indicators for nearby rainwater treatment, and the results of the environmental benefit review are obtained.

[0059] In specific implementation, environmental benefits are mainly used for the combination of blue, green and gray in sponge city projects to ensure the diversity of facilities, avoid excessive single types, and ensure the suitability of facilities and the environment; use green facilities nearby and dispersedly to treat rainwater and pollutants, maximize land use benefits, reduce construction costs, reduce transmission costs and vertical transmission risks, and disperse overflow rainwater discharge.

[0060] Specifically, refer to Figure 8 , Figure 8 It is a schematic diagram of the suitability standards for facility selection. The facility selection information is used to ensure that the facility selection is suitable for the project type. When there are facilities that are not suitable for selection in the declared project, the facility selection is judged to be unreasonable and the facility parameters are identified in the drawings.

[0061] refer to Fig. 9 , Fig. 9 It is a standard schematic diagram of the recommended proportion of facilities. The proportion of facility allocation is used to ensure the diversity of facilities, avoid too much single type, and ensure the suitability of facilities and the environment. Calculate the proportion of sunken green space rate to green space, the proportion of green roof to green space, and the proportion of permeable pavement to impermeable pavement in the application plan, and compare them with the corresponding index requirements of different types of new construction and reconstruction projects. If they are all greater, the facility allocation ratio is reasonable, otherwise it is unreasonable. The underlying surface and facility parameters are identified in the drawings.

[0062] The evaluation index of uniform distribution of facilities refers to allocating the index to each zone and each facility, making full use of the corner land, maximizing the land use efficiency of the last square meter, calculating whether the facility allocation ratio of each zone is reasonable, and statistically calculating the proportion of reasonable zones in the total number of zones, and judging the excellent, good, medium and poor by percentage.

[0063] The index of nearby rainwater treatment refers to the index of using green facilities to treat rainwater and pollutants nearby and dispersedly, which is used to maximize the land use benefits, reduce construction costs, reduce transmission costs and vertical transmission risks, and disperse the overflow rainwater. Calculate the annual runoff control rate of each sub-district, whether it meets the standard, and calculate the proportion of sub-districts that meet the standard in the total number of sub-districts, and judge the excellent, good, medium and poor by percentage.

[0064] Furthermore, the rationality review of the standard urban construction map also includes: Determine the input-output ratio and cost range based on the drawing review parameters and sponge city planning information; An economic benefit review is conducted based on the input-output ratio and cost range to obtain the economic benefit review results.

[0065] It is understandable that economic benefits are used to evaluate output, assess investment benefits, and optimize the efficiency of capital utilization.

[0066] The input-output ratio is a real completion indicator of the sponge city project. At the same time, the investment should not be too high or too low. The output benefit should be included in the economic benefit evaluation, and the investment in unit volume of rainwater treatment should be evaluated. The investment ratio should be compared with that of similar high-quality projects to evaluate the level.

[0067] The input-output ratio is calculated by dividing the declared sponge investment by the designed storage capacity. The recommended input-output ratio is calculated by the average input-output ratio of the same type of new or expanded projects with high input-output ratio evaluation levels that have been evaluated in the system. The designed storage capacity is the same as the annual runoff pollution control rate evaluation. The more projects evaluated in the system, the more reasonable the input-output ratio evaluation is, and the more investment guidance it has, thereby optimizing the sponge investment benefits at a macro level and improving the efficiency of sponge capital utilization.

[0068] refer to Fig.10 , Fig.10 This is a schematic diagram of the cost range evaluation process. The cost range refers to a certain range in the unit cost of facilities. The total cost range can be calculated according to the scale of the facilities used and compared with the declared sponge funds. When the declared funds are not within the range, it is necessary to focus on the sponge investment.

[0069] The overall evaluation of the project refers to the overall evaluation recommendation conclusion given based on the above 11 evaluation conclusions. The overall evaluation can be dynamically configured, and which evaluation levels of the sub-indicators can be recommended for passing can be configured according to customer requirements. Fig.11 , Fig.11 Configure a rule diagram for the project overall evaluation rules. When all these requirements are met, the sub-indicator evaluation is completed, and the system will automatically give a conclusion on whether the recommended project has passed the review.

[0070] Furthermore, after generating the overall review result of the project according to the review results of the output benefits, the review results of the environmental benefits and the review results of the economic benefits, the following is further included: When the overall review result of the project is not passed, a randomly combined sponge city project plan is generated through the preset particle swarm model; Calculate the annual runoff control rate and cost of each sponge city project plan; The target sponge city project plan is determined by the Pareto optimization strategy based on the annual runoff control rate and cost; Update the target sponge city construction map according to the target sponge city project plan.

[0071] It is worth noting that in the automatic review, when it is found that the annual runoff control rate of a sub-district does not meet the standard, the optimization program will use the facilities in the facility library and randomly combine them at different scales to combine 30 sets of plans. Each set of plans will calculate the annual runoff control rate and cost of the sub-district, and use Pareto optimization to find the best plan. Then, the 30 plans will be combined for the second time. The combination of each of the 30 plans for the second time uses the particle swarm algorithm to make the plan close to the optimization plan found last time, and then the best plan will be selected from the 30 plans. This will be repeated 30 times to find the plan with the annual runoff control rate meeting the standard and the lowest cost, which is the best plan. When combining facilities, the selection of facilities and the recommended proportion of facilities will be considered not less than the recommended proportion.

[0072] In the specific implementation, the optimization plan outputs the type, scale, and storage capacity of the LID facilities. The plan achieves the lowest investment cost while meeting the indicators. The optimized zoning facility scale will be written on the corresponding zoning drawings for intuitive reference by design reviewers, and can be directly exported to CAD files for printing to improve the visualization of the modified plan.

[0073] This embodiment conducts a rationality review on the standard urban construction drawings, and the rationality review includes an output benefit review, an environmental benefit review, and an economic benefit review; generates a project overall review result based on the output benefit review result, the environmental benefit review result, and the economic benefit review result; when the project overall review result is passed, conducts a rationality review on the standard urban construction drawings, and the rationality review includes an output benefit review, an environmental benefit review, and an economic benefit review. Through reviews in multiple different dimensions, the review accuracy of the target sponge city construction drawings is improved, and the feasibility of the sponge city project is improved.
