Description

Technical Field

[0001] The present invention belongs to the technical field of automatic environmental assessment systems, and relates to an atmospheric environmental impact assessment system and an assessment method, and in particular to an atmospheric environmental assessment system and a method based on a cloud platform. Background Art

[0002] In order to strengthen the supervision and management of environmental impact assessment and ensure the quality of environmental impact assessment work, based on the current normalization of technical review, an efficient and unified platform tool support is needed. The platform should integrate the basic data and professional models required for environmental impact assessment.

[0003] The operation of atmospheric environmental impact prediction models is highly professional, and small and medium-sized environmental assessment agencies may not fully possess the ability to conduct independent simulations, and need to entrust third-party professional model service providers to carry out prediction simulations. The time and quality of such entrusted calculations are uncontrollable, the cost of entrusted calculations is increased, and the maintenance cost is high. If the atmospheric environmental assessment support data lacks unified standards and channels, there may be a possibility that some third-party environmental assessment service agencies will fabricate data. It is necessary to collect and produce a set of high-resolution and reliable support data, and verify and optimize the accuracy of the data. At the same time, the price of data services should be relatively affordable and convenient for industry use.

[0004] The traditional PC version of atmospheric environmental assessment software can only meet a small part of the needs. Its core concept is to treat each construction project as a completely independent project, without considering the interconnection between the project and other projects in the regional context, which jointly affect the changes in atmospheric capacity and the constraints of the "three lines and one list". From the perspective of the review of a single project, the traditional PC version of atmospheric environmental assessment lacks a lot of process information, which brings a large workload and uncertainty to the technical review of environmental assessment. Summary of the invention

[0005] The present invention provides an atmospheric environmental assessment system and method based on a cloud platform, which provides a convenient atmospheric environmental impact assessment tool for environmental management departments and the environmental assessment industry, standardizes input data, model parameter settings and result chart files, so that third-party environmental assessment units can economically and efficiently carry out atmospheric environmental impact assessment simulation work, and so that environmental management departments can carry out comprehensive applications such as technical review of construction projects, meet the "three lines" constraints, connect with pollution discharge permits, and dynamically calculate atmospheric capacity.

[0006] The technical solution of the present invention is: an atmospheric environmental assessment system based on a cloud platform, comprising a supporting data module, a model module and a cloud platform software implementation module; wherein the cloud platform software implementation module is the input and output end of the system, and manages and controls the supporting data module and the model module; the supporting data module acquires and stores the basic data required for the atmospheric environmental assessment, and according to the command input control of the cloud platform software implementation module, the supporting data module provides the stored basic data to the model module, and the model module processes and processes the basic data to obtain the evaluation result, and then outputs the evaluation result through the cloud platform software implementation module;

[0007] The supporting data module includes an atmospheric data collection submodule, an atmospheric data calculation submodule, an atmospheric data calibration submodule and an atmospheric data storage submodule. The atmospheric data in the supporting data module include geographic basic data, pollution inventory data, meteorological climate data and environmental management data.

[0008] The model module includes an atmospheric risk prediction model and an atmospheric concentration prediction model; the cloud platform software implementation module includes an interface implementation submodule, a database table management submodule, a scheduling and monitoring submodule, and a permission management submodule.

[0009] Furthermore, the atmospheric risk prediction model and atmospheric concentration prediction model in the model module are iterative calculation models of time plus three-dimensional space, and the data in the database are the initial values ​​and boundaries of the iterative calculation model; the atmospheric risk prediction model includes the SLAB risk prediction model and the AFTOX risk prediction model; the atmospheric concentration prediction model includes the AERSCREEN concentration prediction model, the AERMOD concentration prediction model, the CALPUFF concentration prediction model and the CMAQ concentration prediction model.

[0010] Furthermore, after the atmospheric data collection submodule collects geographic basic data, pollution inventory data, meteorological climate data and environmental management data, it provides these basic data to the atmospheric data calculation submodule for calculation and processing, and then provides them to the atmospheric data calibration submodule for calibration, and finally enters them into the temporary database through the atmospheric data storage submodule. It also includes a basic database, and all data in the temporary database are automatically transferred to the basic database and stored for a long time; the atmospheric data collection submodule also collects basic data in the basic database and directly enters the required data in the basic database into the temporary database

[0011] Furthermore, the interface implementation submodule of the cloud platform software implementation module is used for GIS display and operation, the database table management submodule is used for multi-source and multi-dimensional data operations and model result report generation; the scheduling and monitoring submodule is used to implement emission source management; and the authority management submodule is used to manage and control the authorities of each user under the cloud platform.

[0012] A cloud-based atmospheric environmental assessment system method, using the above-mentioned cloud-based atmospheric environmental assessment system, includes the following steps:

[0013] Step 1: Input the project location into the cloud platform software implementation module, and the database table management submodule in the cloud platform software implementation module automatically loads the longitude and latitude area compliance judgment;

[0014] Step 2: The supporting data module collects, calculates and calibrates the basic data of factory boundaries, pollutants, pollution source emissions, Class I environmental protection areas, building information near pollution sources, ground meteorology, sounding meteorology and environmental status monitoring in the target area, and then enters them into the database, which is managed by the database table management submodule in the platform software implementation module;

[0015] Step 3: Implement the submodule through the interface in the platform software implementation module, select the atmospheric risk prediction model and atmospheric concentration prediction model in the model module to perform prediction calculations on the data in the database to obtain atmospheric environment prediction data.

[0016] Furthermore, in step three, the cloud platform software implementation module converts the data format of the data in the database according to the selected atmospheric risk prediction model and atmospheric concentration prediction model, and the converted format matches the selected atmospheric risk prediction model and atmospheric concentration prediction model.

[0017] Furthermore, the cloud platform software implementation module also includes a basic data input submodule. In step one, it also includes inputting the basic data of the project's new pollution source investigation and the basic data of the environmental air protection target into the cloud platform software implementation module.

[0018] Furthermore, in step one, the regional meteorological evaluation factors and evaluation criteria are input into the cloud platform software implementation module;

[0019] In step three, there is also a data fusion step, in which the platform software implementation module converts the data format of the atmospheric environment prediction data obtained by different atmospheric risk prediction models and atmospheric concentration prediction models, and matches and fuses the converted data to obtain the atmospheric environment prediction data after matching and fusion;

[0020] The platform software implementation module automatically calculates and compares the matched and integrated atmospheric environment prediction data with the meteorological evaluation factors and evaluation standards to generate the atmospheric environment evaluation results.

[0021] Furthermore, between step one and step two, there is also a preliminary prediction step, in which the cloud platform software implementation module automatically makes a preliminary prediction of the atmospheric environment based on the input project's newly added pollution source investigation basic data, environmental air protection target basic data, regional meteorological evaluation factors and evaluation standards; if the atmospheric environment evaluation is greater than the preset value in the evaluation standard, then the process proceeds to step two; if the atmospheric environment evaluation is less than the preset value in the evaluation standard, then the pollution is considered to be serious, and according to the severity, the interface implementation submodule reminds the operator to conduct further investigation on the pollution source to supplement the basic data, or directly generates the atmospheric environment evaluation result.

[0022] Furthermore, basic data for monitoring the current environmental situation are collected from the national meteorological observation platform, basic data for ground meteorology and sounding meteorology are simulated and produced by cloud platform software modules, and basic data on factory boundaries, pollutants, emissions from pollution sources, Class I environmental protection zones and buildings near pollution sources in the target area are collected from the environmental protection platform at the project selection site. The above basic data cannot be changed or interfered with by the operator.

[0023] The advantages of the present invention are:

[0024] 1. Efficiency: The existing atmospheric environmental assessment process takes three weeks to collect meteorological, topographic, land type and ambient air quality data, and then it takes another day to a week to simulate the estimation model and prediction model. The overall time spent can be up to half a month. This platform integrates various basic data and professional models, and the calculation results can generally be obtained within 1 day.

[0025] 2. Accuracy: Existing PC-side environmental assessment model processing often loses a lot of process data, and there may be room for fraud or improper model parameter settings, resulting in unreasonable prediction results. This system unifies data collection and production, strictly controls data quality, standardizes and intelligentizes model parameter configuration, and reduces errors caused by improper human settings of the model. At the same time, the cloud platform characteristics can record all process information to ensure that the calculation results correspond to their input data and parameter settings one by one, eliminate the phenomenon of "putting the wrong hat on the wrong head", and facilitate project evaluation and project review.

[0026] 3. Comprehensiveness: It integrates various data required for atmospheric environmental impact assessment and models recommended by various guidelines to meet the needs of various scenarios and levels of assessment. In addition, by strengthening the construction and management of background pollution source lists, dynamically updating the lists of projects that have been built, are under construction, and are planned to be reduced, and dynamically calculating atmospheric capacity, the environmental management department can more efficiently review and verify project status.

[0027] 4. Economical: The existing first-level assessment projects need to purchase ground meteorological, sounding observation, cloud cover and air quality data, which costs nearly 10,000 yuan. If a third-party model simulation service provider is hired to carry out atmospheric environmental assessment, the starting price is more than 50,000 yuan. This system can significantly reduce user costs while ensuring the accuracy of data and models. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] This section is an embodiment of the present invention, which is used to explain and illustrate the technical solution of the present invention.

[0032] The system of the present invention is an atmospheric environmental assessment system based on a cloud platform, comprising a supporting data module, a model module and a cloud platform software implementation module; the supporting data module comprises an atmospheric data collection submodule, an atmospheric data calculation submodule, an atmospheric data calibration submodule and an atmospheric data storage submodule; the model module comprises an atmospheric risk prediction model and an atmospheric concentration prediction model; the cloud platform software implementation module comprises an interface implementation submodule, a database table management submodule, a scheduling monitoring submodule and an authority management submodule.

[0033] The cloud platform software implementation module is the input and output end of the system, managing and controlling the supporting data module and the model module; the supporting data module acquires and saves the basic data required for atmospheric environmental assessment, and according to the command input control of the cloud platform software implementation module, the supporting data module provides the saved basic data to the model module, and the model module processes and handles the basic data to obtain the evaluation results, and then outputs the evaluation results through the cloud platform software implementation module.

[0034] The atmospheric data in the supporting data module include geographic basic data, pollution inventory data, meteorological climate data and environmental management data.

[0035] The atmospheric risk prediction models include the SLAB risk prediction model and the AFTOX risk prediction model; the atmospheric concentration prediction models include the AERSCREEN concentration prediction model, the AERMOD concentration prediction model, the CALPUFF concentration prediction model and the CMAQ concentration prediction model.

[0036] The interface implementation submodule of the cloud platform software implementation module is used for GIS display and operation, the database table management submodule is used for multi-source and multi-dimensional data operations and model result report generation; the scheduling and monitoring submodule is used to implement emission source management; and the authority management submodule is used to manage and control the authorities of each user under the cloud platform.

[0037] The method of the present invention uses the above-mentioned cloud platform-based atmospheric environmental assessment system, and specifically includes the following steps:

[0038] Step 1: Input the project location into the cloud platform software implementation module, and the database table management submodule in the cloud platform software implementation module automatically loads the longitude and latitude area compliance judgment;

[0039] Step 2: The supporting data module collects, calculates and calibrates the basic data of factory boundaries, pollutants, pollution source emissions, Class I environmental protection areas, building information near pollution sources, ground meteorology, sounding meteorology and environmental status monitoring in the target area, and then enters them into the database, which is managed by the database table management submodule in the platform software implementation module;

[0040] Step 3: Implement the submodule through the interface in the platform software implementation module, select the atmospheric risk prediction model and atmospheric concentration prediction model in the model module to perform prediction calculations on the data in the database to obtain atmospheric environment prediction data.

[0041] The project location can be entered by selecting a point on the map or entering longitude and latitude.

[0042] The cloud platform software implementation module also includes a basic data input submodule. In step one, it also includes inputting the pollution source investigation basic data and the ambient air protection target basic data into the cloud platform software implementation module.

[0043] In step one, it also includes inputting the regional meteorological evaluation factors and evaluation standards into the cloud platform software implementation module; in step three, the platform software implementation module automatically calculates and compares the atmospheric environment prediction data with the meteorological evaluation factors and evaluation standards to generate the atmospheric environment evaluation results.

[0044] Between step one and step two, there is also a preliminary prediction step. The cloud platform software implementation module automatically makes a preliminary prediction of the atmospheric environment based on the input pollution source investigation basic data, environmental air protection target basic data, regional meteorological evaluation factors and evaluation standards; if the atmospheric environment evaluation is greater than the preset value in the evaluation standard, then enter step two; if the atmospheric environment evaluation is less than the preset value in the evaluation standard, it is considered that the pollution is serious. According to the severity, the sub-module is implemented through the interface to remind the operator to conduct further investigation on the pollution source to supplement the basic data, or directly generate the atmospheric environment evaluation results.

[0045] Step one also includes sensitive point input, and the location and evaluation criteria of the sensitive points are input into the cloud platform software implementation module; in step three, the generated atmospheric environment evaluation results specifically generate corresponding evaluation results for sensitive points.

[0046] Since the input and output data formats of different prediction models are different, in order to realize the same platform for all models, this system adds the step of converting the basic data into the corresponding matching format of the model, and the data after the model calculation is also converted into the standard format set by the system.

[0047] Another embodiment of the present invention is described below with reference to the accompanying drawings.

[0048] The atmospheric environmental assessment system based on the cloud platform of the present invention is as follows Figure 1 As shown, this is an environmental assessment system with cloud computing function. By integrating air quality data, terrain data, and meteorological data into the cloud, it provides professional environmental assessment conclusion reports through cloud computing.

[0049] The method of using the system and the method of the present invention are as follows Figure 2 and Figure 3 As shown, the following is an example to illustrate this method.

[0050] First, the user remotely enters the system through an Internet computer, and the system interface is displayed on the user's computer display, with a project tree on the left and a map interface on the right.

[0051] When using this system for atmospheric environmental assessment, users can start a new project and select the project location by entering longitude and latitude or selecting a point on the map. The map interface on the right will then automatically jump to the corresponding area. The system will automatically determine the administrative region where the project is located and whether the air quality in that administrative region meets the standards based on the project location, and will mobilize the corresponding database resources and display them on the map interface on the right.

[0052] Then, users can input basic data by themselves, or use the basic data of this system, or choose a combination of the two; basic data include regional factory boundaries, pollutants, pollution source emissions, environmental protection class I areas, building information near pollution sources, ground meteorology, sounding meteorology and environmental status monitoring. Taking pollutants as an example, after the project is activated, the user clicks the pollutant button in the interface. The system has built-in basic parameters and evaluation standards for 10 pollutants (SO2, NO2, CO, O3, PM25, PM10, TSP, NOX, Pb, BaP). No settings are required. Users can edit and save pollutant properties through the edit button on the right, and delete the unnecessary pollutants through the delete button. If the project pollution is not in the built-in pollutants, you can click the new function to add custom pollutants, such as custom gaseous and particulate matter. Users can fill in relevant parameters and evaluation standards according to pollution properties, and click Save to add pollutants. If there are no relevant pollutant parameters, users only need to fill in the evaluation standards for pollutants. The system defaults to general pollutant parameters. Click Confirm to add pollutants. Other basic data also include status monitoring, i.e. the long-term monitoring results of some automatic air monitoring stations; it also includes factory boundaries, which can be set by inputting longitude and latitude and selecting points on a map; it also includes a type of evaluation area, which is set in the same way as the factory boundary; it also includes sensitive points, which can be located by directly filling in longitude and latitude or selecting points on a map, and the edit button on the right of the sensitive point can be used to re-edit the sensitive point information; it also includes building washdown, which can set the building name, range and height; it also includes pollution sources, i.e. point sources, line sources, surface sources and volume sources of pollution, and sets the location, length, range, vertical length of volume sources, emission time and emission per unit time of these pollution; it also includes meteorological data.

[0053] After the basic data is input, the user clicks on the model option in the project tree and selects the environmental impact assessment prediction model to process the basic data.

[0054] Taking the AERSCREEN concentration prediction model as an example, the user clicks on the AERSCREEN model in the project tree on the left to enter the AERSCREEN solution list interface, where the solution can be managed or a new solution can be added. Click Create or Edit to enter the solution editing interface. The AERSCREEN solution editing interface is divided into pollution sources and pollutants, meteorological parameters, surface parameter modules, prediction point parameters, and project parameter modules. By checking the pollution sources and pollutants entered previously, select the pollutants and pollution sources to participate in the calculation. The surface parameters can be divided into sectors according to the land in the location. The time period is selected in seasons or months; select climate humidity; and finally select the ground type of the sector: such as water surface, grassland, deciduous forest, coniferous forest, wetland or swamp, cropland, city, and desert wasteland. After all parameters are selected, click Generate Recommended Parameters. Fill in the prediction point parameters, the height of the project prediction point from the ground, the maximum calculation distance, and select the factory boundary. Fill in the project parameters: When selecting a city in the urban and rural types, the urban population must be filled in, and the population number is not required when selecting a rural area. If the calculation takes NO2 reaction into account, you need to tick the reaction option, then select the OLM or PVMRM method, fill in the background ozone concentration and the ratio of NO2 to NOX in the flue, and complete the NO2 reaction setting. Check to consider building downwash, select the previously defined building downwash scheme in the drop-down menu on the right, and complete the building downwash setting. AERSCREEN can calculate fumigation and coastline fumigation. Check to consider the calculation. If you check the coastline fumigation, you need to enter the minimum coastline distance and the direction of the minimum coastline distance. After completing all the required options for pollution sources and pollutants, meteorological parameters, surface parameters and prediction point parameters, and the optional options for project parameters, click Submit Plan below, and the system will start the AERSCREEN calculation for the plan. When the AERSREEN operation is successful and the result is successfully output, the calculation of this plan is completed. You can click on the calculation result to view it.

[0055] Taking the AERMOD concentration prediction model as an example, the user clicks on the AERMOD model in the project tree on the left, selects the AERMOD meteorological model in the submenu, and enters the AERMOD scheme summary interface. The ground parameter settings are consistent with the setting method in the AERSCREEN scheme. The meteorological parameters can be selected to randomize the wind direction and adjust u under stable conditions of light wind. Select the previously saved ground meteorological data and sounding data under the meteorological data, and finally click Save to complete the settings. Click the prediction grid to enter the prediction grid scheme summary interface, click Edit or Create to enter the prediction scheme setting interface. The prediction grid only needs to set the evaluation range side length, and check the sensitive points to be calculated, and click Save to complete the settings. The system automatically sets the grid spacing according to the guidelines and the evaluation range side length. Click AERMOD prediction on the left to enter the AERMOD calculation scheme summary interface. Click Add or Scheme Edit to enter the AERMOD prediction scheme setting interface. The AERMOD scheme is divided into three sub-tabs, namely basic elements, deposition parameters and NO2 parameters. The basic elements are realized by checking. You can check the emission scenarios (one pollutant, multiple pollution sources) set before, select the previously saved AERMET forecast meteorological scheme and forecast grid scheme, and finally select the required result data averaging time to complete the emission scenario setting. Model options can be selected according to project requirements, whether to consider terrain, dry and wet deposition, consider building washdown and select building washdown scheme, whether to consider urban effects, whether to react with NO2, and finally select the output maximum value sequence number to complete the basic element setting. Click on the deposition parameter setting to enter the setting interface. You can use the system default or click on more gas-related parameters to calculate by yourself. Click to complete the setting. Enter the NO2 reaction interface, click on the setting operation after the chemical reaction for NO2, and the system defaults to the environmental ratio method without the user entering parameters. If the user clicks the OLM method, the background ozone concentration and the ratio of NO2 to NOX in the flue need to be entered according to the interface. If the user selects the PVMRM method, the background ozone concentration and the ratio of NO2 to NOX in the entire flue and the environment need to be entered. After completing all the above AERMOD calculation parameter settings, click the Submit Plan button below to save the plan, start the calculation of the plan, and generate a submenu for the plan below the AERMOD prediction of the project number. The submenu of the plan includes calculation logs and calculation results. Above the prediction results is the predicted scenario plan. Click to select the pollutant scenario you need to view. After clicking, the system displays the maximum value summary table by default, and selects the large value sequence option as needed. The table shows the maximum landing concentration, occupancy rate and compliance evaluation of the sensitive points required for the guideline prediction in hours, daily averages and annual averages. Select the detailed data display of daily averages, annual averages, short-term (hours) and atmospheric protection distances in the drop-down results. Daily averages, annual averages, and short-term data are all composed of three data graphs: concentration graph, data table, and excessive grid information. The calculation results also have superposition schemes. Click the superposition scheme in the project tree to enter the superposition scheme summary interface.Click Edit and Add to enter the scheme setting interface. Pull down to select the pollutants to be calculated and check the calculated emission scenarios to be superimposed. You can choose addition or subtraction for superposition, and set the superposition coefficient of the scheme. The system provides the site data, regional reduction and regional increase concentrations of the superposition status. The percentage data output after superposition can be customized by the user. When a secondary calculation of PM25 is required, the primary calculation results of PM25 and the coefficient ratios of SO2 and NO2 can be superimposed. After the settings are completed, click Submit below to complete the superposition scheme settings and start the superposition calculation. Click the superposition calculation results of the scheme to view the percentage of superimposed pollutants and the annual average compliance evaluation table, including contribution concentration, current concentration, superimposed concentration, superimposed standard ratio and compliance judgment. The concentration chart below can choose to display the annual average and percentage daily average concentration.

[0056] Finally, the calculation results of the previous step will be combined with the environmental impact assessment factors and environmental impact assessment standards input previously to generate the atmospheric environment assessment results. This result is generally presented in the form of multiple charts and brief text reports. Users can select some chart results for further analysis and calculation to obtain more needed environmental impact assessment results.
