[0057] Beneficial effects of the present invention:

[0058] 1. The intelligent flood control and drainage strategy analysis method based on the grid linkage mechanism proposed in the present invention, compared with the prior art, has the beneficial effect of being divided into multiple grid matrix sub-areas by dividing the urban area into urban grids. This grid division is to manage and monitor the drainage system of the city more accurately. Each grid matrix sub-area has its specific geographical location and boundaries, so that managers can deploy and optimize meteorological sensors, water level sensors and flood control and drainage facility monitoring equipment in a targeted manner. This grid division not only improves the management efficiency of urban infrastructure, but also effectively reduces potential disaster risks and environmental damage. Meteorological sensors, water level sensors and flood control and drainage facility monitoring equipment are also deployed in each urban grid matrix sub-area, and flood control and drainage pump control equipment is set at the boundary bottom line between the sub-areas, which is a key step to ensure the safe and efficient operation of the urban drainage system. The joint monitoring and control capabilities of these devices enable the city to monitor the meteorological conditions and water level changes in each area in real time, and adjust and optimize the operation status of the drainage system in a timely manner, thereby effectively responding to potential flood control and drainage processes. At the same time, by using meteorological sensors to collect meteorological data in real time from the urban grid matrix sub-areas, key parameters such as temperature, humidity, wind speed and precipitation are collected in real time. These real-time collected meteorological data not only help cities monitor and predict natural disaster risks, but also provide scientific basis and data support for subsequent drainage emergency response. Water level sensors are also used to collect water level data in real time from the urban grid matrix sub-areas to monitor the water level changes in different grid sub-areas within the city. These real-time collected water level data are the key basis for evaluating the operating efficiency of the urban drainage system and responding to potential flood risks. Through the analysis and monitoring of water level data, the operation of drainage facilities can be adjusted and optimized in time to ensure the safety and stability of the city during extreme weather events or natural disasters. Secondly, based on the real-time meteorological data and real-time water level data of each urban network sub-area, the corresponding urban grid matrix sub-areas are screened for flood waiting areas, aiming to identify potential flood warning waiting grid sub-areas. This step analyzes the rainfall and water level changes in each area to determine the areas that are affected or have drainage needs, thereby preparing for further drainage preparations and emergency responses. The purpose of conducting a horizontal and vertical linkage downward drainage strategy analysis on the grid sub-areas to be drained in the city flood warning is to formulate an effective urban drainage plan. By combining the geographical location, water level changes and rainfall data of the region, the optimal drainage path and strategy are analyzed to ensure that the drainage system in each area of ​​the city can operate effectively and minimize the losses and impacts caused by floods. This horizontal and vertical linkage drainage strategy analysis enables the city to respond quickly and efficiently when facing extreme weather events, thereby improving the city's flood prevention capabilities and emergency response rate.Then, based on the strategy of horizontal and vertical linkage downward drainage in the urban flood waiting area, the flood control drainage pump control equipment is used to judge the flood control drainage threshold of the urban flood warning waiting grid sub-area, so as to divide it into the urban low flood drainage grid sub-area and high flood drainage grid sub-area. The key to this step is to accurately judge which areas need priority drainage and enhanced protection to minimize the losses and impacts caused by flood disasters and ensure the safety and stability of the city. By using flood control drainage facility monitoring equipment to evaluate and analyze the drainage capacity in the low flood drainage grid sub-area, including a detailed analysis of the horizontal and vertical drainage capacity, this evaluation can help decision makers understand the actual operation of drainage facilities in each area, timely discover and solve potential drainage problems, and ensure the reliability and stability of the drainage system in emergency situations. The purpose of this paper is to optimize the drainage plan and improve the drainage efficiency. Through the refined drainage strategy, it is to ensure that the low-flood area can be drained in a timely and effective manner, reduce the negative impact of urban floods on life and economy, and ensure the normal operation of the city and the quality of life of residents, thereby increasing the diversity of drainage decision analysis. Finally, the drainage grid sub-areas with high flood conditions are screened for drainage low-load areas to identify areas with low drainage loads. The key to this step is to give priority to areas with sufficient drainage capacity. By screening out low-load areas, the water volume in high-flood areas can be effectively diverted, the load on the drainage system can be reduced, and the overall drainage efficiency can be improved. In addition, based on the low-load drainage areas adjacent to the upper positions during high flood conditions in the city, flood control and drainage pump control equipment is used to conduct an upper diversion and linkage drainage strategy analysis on the urban high flood drainage grid sub-areas, aiming to optimize the operation of the high flood drainage system. Through precise diversion and linkage strategies, the water flow can be effectively regulated to ensure that the drainage capacity of high flood areas is utilized to the greatest extent, thereby enhancing the city's risk resistance and response capabilities to flood disasters.

It can realize any smart flood control and drainage strategy analysis method based on the grid linkage mechanism described in the present invention, and is used to combine the operations between computer programs running on each module to realize the smart flood control and drainage strategy analysis method based on the grid linkage mechanism. The internal structures of the system cooperate with each other, which can greatly reduce duplication of work and manpower investment, and can quickly and effectively provide a more accurate and efficient smart flood control and drainage strategy analysis process based on the grid linkage mechanism, thereby simplifying the operation process of the smart flood control and drainage strategy analysis system based on the grid linkage mechanism.

[0072] In the embodiment of the present invention, please refer to Figure 1 As shown, it is a schematic diagram of the steps of the intelligent flood control and drainage strategy analysis method based on the grid linkage mechanism of the present invention. In this example, the intelligent flood control and drainage strategy analysis method based on the grid linkage mechanism includes the following steps:

[0073] Step S1: Divide the urban area into urban grids to obtain various urban grid matrix sub-areas; deploy meteorological sensors, water level sensors and flood control and drainage facility monitoring equipment in each urban grid matrix sub-area, and set up flood control and drainage pump control equipment at the boundary bottom line between each urban grid matrix sub-area; collect grid area data of each urban grid matrix sub-area in real time through meteorological sensors and water level sensors to obtain meteorological real-time data and water level real-time data of each urban grid sub-area;

[0074] In an embodiment of the present invention, a spatial distribution map of each drainage pipe in an urban area is drawn by using GIS technology, and different urban grid sub-areas are allocated and divided according to the statistical analysis of the pipe network density and flow load based on the spatial distribution map, so as to obtain each urban grid matrix sub-area. Secondly, corresponding meteorological sensors, water level sensors and flood control and drainage facility monitoring equipment are deployed in each urban grid matrix sub-area previously obtained, and flood control and drainage water pump control equipment is set at the boundary bottom line between each urban grid matrix sub-area. For example, a city installs meteorological sensors in each grid sub-area for real-time monitoring of meteorological parameters such as rainfall and wind speed, and water level sensors are installed at the location of the drainage pipe network to accurately grasp the changes in the discharge water level during the flood season. In addition, water pump control equipment is also set at the boundary between each grid, so as to adjust the operating state of the water pump control equipment according to the real-time monitoring data of the flood control and drainage facility monitoring equipment, so as to ensure the drainage efficiency and safety in each grid area. Then, the meteorological data in each urban grid matrix sub-area is collected in real time by starting the corresponding meteorological sensor, so as to collect and record meteorological information such as rainfall intensity, wind speed, temperature, etc. in real time, so as to obtain the meteorological real-time data of each urban grid sub-area. The corresponding water level sensors are activated to collect real-time water level data in each urban grid matrix sub-area, so as to monitor the changes in water levels in the drainage network in real time and promptly detect urban waterlogging or waterlogging, thereby ensuring that the urban drainage system operates efficiently and stably during the flood season, and finally obtaining real-time water level data in each urban grid sub-area.

[0075] Step S2: Based on the real-time meteorological data and water level data of each urban grid sub-region, the corresponding urban grid matrix sub-region is screened for flood drainage areas to obtain urban flood warning grid sub-regions to be drained; the horizontal and vertical linkage downward drainage strategy of the urban flood warning grid sub-regions to be drained is analyzed to generate a horizontal and vertical linkage downward drainage strategy for the urban flood drainage area;

[0076] In an embodiment of the present invention, real-time rainfall data in each urban network sub-area is collected and extracted from the real-time meteorological data of each urban network sub-area, and the real-time meteorological rainfall data and real-time water level data of each urban network sub-area previously monitored are synchronously aligned in time series by using methods such as interpolation or timestamp alignment, so as to time align and synchronize the data collected by different sensors, ensure that the rainfall data and the water level data are consistent in time, and perform flood warning analysis on the corresponding urban grid matrix sub-area by combining the rainfall and water level of each urban network sub-area previously obtained after time series synchronization, so as to summarize and analyze the rainfall and water level data of each sub-area, identify potential drainage difficulty areas or areas where drainage problems have already occurred, and determine which grid sub-areas will have waterlogging or poor drainage, and it is necessary to give priority to drainage warning and screen them out, thereby obtaining the grid sub-areas for urban flood warning. Then, the drainage strategy of the previously screened urban flood warning grid sub-areas to be discharged is analyzed to identify their relative positions in the urban area, and the water flow linkage effect between different grid sub-areas in the city is fully considered, that is, the principle of natural drainage from areas with high water levels to areas with low water levels. The flood control drainage water pump control equipment in the horizontal and vertical directions of the urban flood warning grid sub-areas to be discharged is started to drain water downward, and finally a horizontal and vertical linkage downward drainage strategy for the urban flood area to be discharged is generated.

[0077] Step S3: Based on the horizontal and vertical linkage downward drainage strategy of the urban flood situation waiting area, the flood control drainage pump control equipment is used to divide the flood control drainage threshold of the urban flood warning waiting grid sub-area to be drained, and the urban low flood situation drainage grid sub-area and the urban high flood situation drainage grid sub-area are obtained; the flood control drainage facility monitoring equipment is used to evaluate and analyze the drainage capacity of the flood control drainage pump control equipment in the horizontal and vertical directions in the urban low flood situation drainage grid sub-area to obtain the horizontal and vertical drainage capacity status of the low flood situation sub-area; based on the horizontal and vertical drainage capacity status of the low flood situation sub-area, the urban low flood situation drainage grid sub-area is analyzed for the horizontal and vertical blocking and oblique downward linkage drainage strategy, and the urban low flood situation horizontal and vertical load blocking and oblique downward linkage drainage strategy is generated to perform the corresponding urban low flood situation load drainage optimization work;

[0078] In an embodiment of the present invention, by using the horizontal and vertical linkage downward drainage strategy of the urban flood area to be discharged obtained by previous analysis, the flood control drainage pump control device is used to control the drainage in the horizontal and vertical directions of the corresponding urban flood warning grid sub-area to be discharged, so as to start the relevant drainage pumps according to the preset control strategy to speed up the discharge speed of the water body in the corresponding area to be discharged, and statistically analyze the actual drainage capacity value and the actual terrain slope value of the drainage network in the corresponding urban flood warning flood control drainage grid sub-area, so as to quantitatively calculate the expected drainage of each grid sub-area, and at the same time, by using the preset flood control drainage threshold value to compare and judge the expected drainage of each grid sub-area obtained by the previous quantitative calculation, if it is less than the preset flood control drainage threshold value, then the corresponding urban flood warning grid sub-area to be discharged is divided into the urban low flood drainage grid sub-area; and if it is greater than or equal to the preset flood control drainage threshold value, it needs to be processed by diversion drainage, and then the corresponding urban flood warning grid sub-area to be discharged is divided into the urban high flood drainage grid sub-area. Secondly, by using the flood control and drainage facility monitoring equipment deployed in the area, the drainage capacity of the flood control and drainage pump control equipment at the corresponding horizontal and vertical positions in the urban low flood drainage grid sub-area is evaluated and analyzed, so as to monitor the operating status and drainage efficiency of the flood control and drainage pump control equipment in the horizontal and vertical positions in the area in real time, so as to evaluate the operating load performance of the control equipment in the actual drainage process, including four drainage capacity conditions: the drainage capacity of the control equipment in the horizontal and vertical directions is not loaded, the control equipment drainage is loaded in the horizontal direction and the control equipment drainage is not loaded in the vertical direction, the control equipment drainage is not loaded in the horizontal direction and the control equipment drainage is loaded in the vertical direction, and the drainage capacity of the control equipment in the horizontal and vertical directions is loaded, so as to obtain the horizontal and vertical drainage capacity conditions of the low flood sub-area. Then, by combining the horizontal and vertical drainage capacity conditions of the low-flood sub-areas obtained in the previous analysis, the corresponding urban low-flood drainage grid sub-areas are analyzed for the linkage drainage strategy of the water pump control equipment in the corresponding directions, so as to adopt the corresponding drainage opening strategy according to the different drainage capacities of the horizontal and vertical water pump control equipment to maximize the drainage efficiency of the existing drainage facilities, and finally generate the urban low-flood horizontal and vertical load closure and oblique opening linkage drainage strategy to perform the corresponding urban low-flood load drainage optimization work.

[0079] Step S4: Analyze the upper adjacent drainage low-load area of ​​the urban high flood drainage grid sub-area to obtain the upper adjacent drainage low-load area of ​​the urban high flood situation; based on the upper adjacent drainage low-load area of ​​the urban high flood situation, use the flood control drainage pump control equipment to analyze the upper diversion linkage drainage strategy of the urban high flood drainage grid sub-area, generate the upper diversion linkage drainage strategy of the urban high flood situation, so as to perform the corresponding urban high flood situation diversion drainage optimization work.

[0080] In an embodiment of the present invention, the neighboring relationship of each drainage grid sub-area is identified and determined by performing an identification analysis on the previously determined urban high flood drainage grid sub-area with an upper adjacent relationship, that is, the upper adjacent area of ​​each area is found therefrom, and the data related to the drainage capacity in each urban high flood drainage grid sub-area with an upper adjacent relationship is collected and sorted by using a data statistical analysis method, such as the drainage pipe diameter, water pump power, natural drainage capacity, etc. of each area, and the drainage capacity of each grid sub-area is statistically analyzed by performing a drainage capacity statistical analysis on these data to statistically calculate the drainage capacity load statistics of each grid sub-area, that is, the drainage capacity of each area when dealing with a high flood. At the same time, the corresponding urban high flood upper adjacent relationship drainage grid sub-area is screened for low-load areas by combining the drainage capacity load statistics of each upper adjacent drainage area obtained by quantitative calculation previously, so as to identify the area where the load of the pump control equipment is relatively low during the drainage process, thereby obtaining the urban high flood upper adjacent drainage low-load area. Then, by using flood control drainage pump control equipment, the high flood water level in the city's high flood drainage grid sub-area is diverted and uploaded to the previously identified urban high flood upper position adjacent to the low-load drainage area for linkage drainage treatment, aiming to optimize the operation of the drainage system in the city's high flood drainage grid sub-area, and through precise diversion linkage strategies, effectively control the water flow to be diverted upward to areas with lower drainage load capacity, and ensure that the drainage capacity of high flood areas is maximized. Finally, a diversion linkage drainage strategy is generated for urban high flood conditions, thereby realizing the diversion and drainage work in the corresponding urban high flood areas.

For example, a city installs meteorological sensors in each grid sub-area for real-time monitoring of meteorological parameters such as rainfall and wind speed, and installs water level sensors at the location of the drainage network to accurately grasp the changes in the discharge water level during the flood season. In addition, water pump control equipment is also set at the boundary between each grid to adjust the operating status of the water pump control equipment according to the real-time monitoring data of the flood control and drainage facility monitoring equipment to ensure the drainage efficiency and safety in each grid area.

[0105] In an embodiment of the present invention, a spatial distribution topological analysis of the drainage network in the corresponding urban area is performed by combining the spatial distribution position data of the urban area drainage network obtained by previous analysis, so as to establish a detailed drainage network topology map using a spatial topological analysis method based on information including the starting point, end point, connection method, etc. of the drainage pipe, so as to show the connection relationship and layout between the various drainage pipes in the urban area. For example, in a certain urban area, by drawing a topological map of the drainage pipes, the intersection points, branches and main pipe paths between different pipes can be clearly displayed, and finally a spatial distribution topological map of the drainage network in the urban area is obtained.

[0109] In an embodiment of the present invention, by real-time measuring the flow velocity, flow rate, water load and other parameters of each drainage pipe in the relative area within the spatial distribution topology of the urban area drainage network, and estimating the actual flow rate of each drainage pipe by using numerical simulation methods, these data reflect the drainage capacity of each area during the flood season or rainfall events, thereby determining the actual flow rate of the drainage pipes in a certain area, and finally obtaining the spatial drainage distribution flow of the urban area drainage network.

[0110] Step S124: Divide the urban area into urban grids based on the spatial distribution density of the urban area drainage pipe network and the spatial drainage distribution flow of the urban area drainage pipe network to obtain various urban grid matrix sub-areas.

[0111] In an embodiment of the present invention, a spatial analysis method of grid partitioning is used to perform grid matrix division on the corresponding urban area by combining the spatial distribution density of the urban area drainage network and the spatial drainage distribution flow of the urban area drainage network obtained by previous statistical analysis, so as to divide the urban area into multiple regular rectangular grid sub-areas, and each grid sub-area is allocated different pipe network service capabilities according to its pipe network density and flow load. For example, a city divides the entire urban area into dozens of grid sub-areas according to the drainage pipe network density and flow distribution. Corresponding monitoring equipment and flood prevention measures can be set in each area, so as to quickly respond and adjust the operating status of the drainage system in the event of sudden heavy rainfall or flood season, so as to ensure the drainage efficiency and safety within the city, and finally divide each city grid matrix sub-area.

[0112] Further, step S2 includes the following steps:

[0113] Step S21: extracting and processing the real-time meteorological data of each urban network sub-area to obtain the real-time meteorological rainfall data of each urban network sub-area;

[0114] In an embodiment of the present invention, key information including rainfall intensity, rainfall time and rainfall area is collected and extracted from the real-time meteorological data of each urban network sub-area, and the real-time rainfall conditions in each urban network sub-area are analyzed and extracted through data processing and algorithm, and finally the real-time meteorological rainfall data of each urban network sub-area is obtained.

[0115] Step S22: performing time series synchronization and alignment processing on the meteorological real-time rainfall data and water level real-time data of each urban network sub-area to obtain the rainfall time series synchronization data and water level time series synchronization data of each urban network sub-area;

[0116] In an embodiment of the present invention, the meteorological real-time rainfall data and the real-time water level data of each urban network sub-area previously monitored are synchronized and aligned in time series by using methods such as interpolation or timestamp alignment, so as to time align and synchronize the data collected by different sensors, ensure that the rainfall data and the water level data are consistent in time, and unify them into the same time series for subsequent flood situation analysis and drainage strategy formulation, and finally obtain the rainfall time series synchronization data and the water level time series synchronization data of each urban network sub-area.

[0117] Step S23: Based on the rainfall time series synchronization data and water level time series synchronization data of each urban network sub-area, the corresponding urban grid matrix sub-area is screened for flood warning areas to be cleared, so as to obtain the urban flood warning grid sub-area to be cleared;

[0118] In an embodiment of the present invention, by combining the rainfall time series synchronization data and water level time series synchronization data of each urban network sub-area obtained after the previous time series synchronization, the corresponding urban grid matrix sub-area is analyzed for flood warning to be discharged, so as to summarize and analyze the rainfall and water level data of each sub-area, so as to identify potential drainage difficult areas or areas where drainage problems have already occurred. For example, based on the analysis of rainfall data and water level data in a certain urban area, it can be determined which grid sub-areas will have waterlogging or poor drainage, and it is necessary to give priority to drainage warnings and screen them out, and finally obtain the grid sub-areas for urban flood warning to be discharged.

[0119] Step S24: Analyze the horizontal and vertical linkage downward drainage strategy for the urban flood warning waiting grid sub-area to be discharged, so as to generate the horizontal and vertical linkage downward drainage strategy for the urban flood warning waiting area.

For example, for the flood area to be discharged in a certain city, a strategy can be formulated to adjust the drainage equipment in the horizontal and vertical directions, increase the drainage capacity or adjust the drainage pipes to ensure that the drainage systems in various areas can operate efficiently during the flood season, reduce the risk of urban waterlogging, and finally generate a horizontal and vertical linkage downward drainage strategy for the urban flood area to be discharged.

[0121] Further, step S23 includes the following steps:

[0122] Step S231: Based on the rainfall time series synchronization data of each urban network sub-area, the rainfall intensity change rate of the corresponding urban grid matrix sub-area is statistically calculated to obtain the rainfall intensity change rate of each urban network sub-area;

[0123] In an embodiment of the present invention, by combining the previously determined rainfall time-series synchronization data of each urban network sub-area, a statistical calculation of the rainfall change rate is performed on the corresponding urban grid matrix sub-area to collect real-time rainfall data from each monitoring point. These data can be updated every hour or every minute to reflect the temporal distribution and intensity changes of rainfall. By calculating the change rate between rainfall data, the change trend of rainfall intensity in each sub-area can be analyzed. For example, in a gridded sub-area of ​​a city, the change rate of rainfall intensity in different time periods is calculated based on continuous real-time rainfall data, thereby evaluating the increase or decrease trend of rainfall in the area, and finally obtaining the rainfall intensity change rate of each urban network sub-area.

[0124] Step S232: based on the water level time series synchronization data of each urban network sub-area, statistical calculation of the water level rise rate of the corresponding urban network matrix sub-area is performed to obtain the water level rise rate of each urban network sub-area;

[0125] In an embodiment of the present invention, by combining the water level time-series synchronization data of each urban network sub-area obtained by previous analysis, the water level rise rate of the corresponding urban network matrix sub-area is statistically calculated to calculate the rate of change of the water level in each area, that is, the hourly rise of the water level or the change amplitude per minute. For example, in a gridded sub-area of ​​a city, the rate of water level rise is calculated based on continuous water level monitoring data and its water level monitoring time, so as to timely evaluate the waterlogging risks and response measures in the area, and finally obtain the water level rise rate of each urban network sub-area.

[0126] Step S233: Perform regional flood risk assessment analysis based on the rainfall intensity change rate and water level rise rate of each urban network sub-region to obtain the rainfall change flood risk factor and water level rise flood risk factor of each urban network sub-region;

[0127] In an embodiment of the present invention, by combining the specific sizes of the rainfall intensity change rate and the water level rise rate of each urban network sub-area obtained by previous statistical calculations, a risk assessment analysis is performed on the flood impact in the corresponding urban network sub-area to quantitatively analyze the degree of influence of the rainfall change rate and the water level rise rate on the urban flood risk, and finally obtain the rainfall change flood risk factor and the water level rise flood risk factor of each urban network sub-area.

[0128] Step S234: Based on the rainfall change flood risk factor and the water level rise flood risk factor of each urban network sub-region, a comprehensive quantitative calculation of flood risk warning is performed on the corresponding urban network matrix sub-region to obtain a comprehensive flood risk warning score for each urban network sub-region;

[0129] In the embodiment of the present invention, the specific impact degree of the rainfall change flood risk factor and the water level rise flood risk factor of each urban network sub-area obtained by the previous evaluation and analysis is used to assign corresponding flood risk weights to them, and a weighted calculation is performed based on the product of the assigned flood risk weights and the corresponding rainfall change flood risk factor and the water level rise flood risk factor, so as to generate a comprehensive flood risk warning score based on the comprehensive evaluation of rainfall change and water level rise, for example , where is the number of urban network sub-regions, For the The comprehensive flood risk warning score of each city network sub-area, For the The flood risk weight of the rainfall change flood risk factor corresponding to each city network sub-region, For the The rainfall change flood risk factor corresponding to each city network sub-region is: For the The flood risk weight of the water level rise flood risk factor corresponding to each city network sub-area, For the The water level rise flood risk factors corresponding to each urban network sub-area are calculated, and finally the comprehensive flood risk warning score of each urban network sub-area is obtained.

[0130] Step S235: Screen the corresponding urban grid matrix sub-regions for flood risk warning according to the comprehensive flood risk warning score of each urban network sub-region, so as to obtain the urban flood risk warning grid sub-regions for flood risk warning.

[0131] In an embodiment of the present invention, the flood risk warning comprehensive score values ​​of each urban network sub-area previously obtained by quantitative calculation are compared and judged according to a preset flood risk warning threshold value, so as to screen out the urban grid matrix sub-area corresponding to the flood risk warning threshold value that is greater than or equal to the preset flood risk warning threshold value as the flood warning waiting area, so as to select those areas with higher scores as the key monitoring objects according to the flood warning scores of each grid sub-area in the city, so as to ensure that timely response and processing can be carried out when rainfall increases or water levels rise, so as to ensure the control and reduction of urban waterlogging risks, and finally screen out the urban flood warning waiting grid sub-area.

[0132] Further, step S3 includes the following steps:

[0133] Step S31: Based on the strategy of horizontal and vertical linkage downward drainage of the urban flood waiting area, the flood control and drainage pump control equipment is used to perform flood control and drainage control processing on the urban flood warning waiting grid sub-area to be drained, so as to obtain the urban flood warning flood control and drainage grid sub-area;

[0134] In an embodiment of the present invention, by using the horizontal and vertical linkage downward drainage strategy of the urban flood area to be discharged obtained by previous analysis, the flood control drainage pump control equipment is used to control the drainage in the horizontal and vertical directions of the corresponding urban flood warning grid sub-area to be discharged, so as to start the relevant drainage pumps according to the preset control strategy to speed up the discharge rate of the water body in the corresponding area to be discharged, thereby effectively lowering the water level and reducing the loss caused by floods, and finally obtaining the urban flood warning flood control drainage grid sub-area.

[0135] Step S32: Statistical analysis of drainage network capacity and regional terrain slope is performed on the urban flood warning and flood control drainage grid sub-areas to obtain drainage network capacity values ​​and regional terrain slope values ​​of each urban flood control drainage grid sub-area;

[0136] In the embodiment of the present invention, each drainage outlet in the urban flood warning flood control drainage grid sub-area is inspected and measured to statistically analyze the actual drainage capacity of the drainage network in the urban flood warning flood control drainage grid sub-area, thereby obtaining the drainage network capacity value of each urban flood control drainage grid sub-area. At the same time, the terrain slope conditions in the urban flood warning flood control drainage grid sub-area are statistically measured to measure the actual terrain slope value of each grid sub-area, and finally obtain the regional terrain slope value of each urban flood control drainage grid sub-area.

[0137] Step S33: Based on the drainage network capacity value of each urban flood control drainage grid sub-area and the regional terrain slope value, the regional flood control drainage volume calculation formula is used to perform drainage volume statistics calculation on the urban flood warning grid sub-area to be drained, so as to obtain the flood control drainage volume of each urban flood control drainage grid sub-area;

[0138] In an embodiment of the present invention, a suitable regional flood control drainage calculation formula is formed by combining the number parameters of urban flood control drainage grid sub-areas, regional area size, drainage network capacity value, regional terrain slope value, influence coefficient of terrain slope on drainage capacity, influence coefficient of drainage grid sub-area area size on drainage capacity, drainage sensitivity index factor, number parameters of drainage sources, drainage contribution value of drainage sources, drainage specific weight coefficient and related parameters to perform drainage statistics calculation on urban flood warning grid sub-areas to be discharged, so as to quantitatively calculate the expected drainage of each grid sub-area, and finally obtain the flood control drainage of each urban flood control drainage grid sub-area.

[0139] Step S34: Compare and judge the flood control drainage volume of each urban flood control drainage grid sub-area according to the preset flood control drainage volume threshold value. When the flood control drainage volume is less than the preset flood control drainage volume threshold value, the corresponding urban flood warning to-be-drained grid sub-area is divided into an urban low flood drainage grid sub-area; when the flood control drainage volume is greater than or equal to the preset flood control drainage volume threshold value, the corresponding urban flood warning to-be-drained grid sub-area is divided into an urban high flood drainage grid sub-area;

[0140] In an embodiment of the present invention, a comparison is made between the flood control drainage volumes of each urban flood control drainage grid sub-area previously quantified and calculated using a preset flood control drainage volume threshold. If the flood control drainage volume is less than the preset flood control drainage volume threshold, indicating that the actual drainage volume in the area has not reached the threshold of the flood drainage load, the corresponding urban flood warning grid sub-area to be discharged is divided into an urban low flood drainage grid sub-area. If the flood control drainage volume is greater than or equal to the preset flood control drainage volume threshold, indicating that the actual drainage volume in the area has reached the threshold of the flood drainage load and diversion drainage is required, the corresponding urban flood warning grid sub-area to be discharged is divided into an urban high flood drainage grid sub-area.

[0141] Step S35: The flood control and drainage facility monitoring equipment is used to evaluate and analyze the drainage capacity of the flood control and drainage pump control equipment in the horizontal and vertical directions in the low flood drainage grid sub-area of ​​the city, so as to obtain the horizontal and vertical drainage capacity conditions of the low flood sub-area, wherein the horizontal and vertical drainage capacity conditions of the low flood sub-area include no load in the horizontal and vertical directions, load in the horizontal drainage and no load in the vertical direction, no load in the horizontal drainage and load in the vertical direction, and load in the horizontal and vertical directions;

[0142] In an embodiment of the present invention, the drainage capacity of the flood control and drainage water pump control equipment at the corresponding horizontal and vertical positions in the urban low flood drainage grid sub-area is evaluated and analyzed by using the flood control and drainage facility monitoring equipment deployed in the area, so as to monitor the operating status and drainage efficiency of the flood control and drainage water pump control equipment at the horizontal and vertical positions in the area in real time, so as to evaluate the operating load working performance of the control equipment in the actual drainage process, including four drainage capacity conditions: the drainage capacity of the control equipment in the horizontal and vertical directions is not loaded, the drainage of the control equipment in the horizontal direction is loaded and the drainage of the control equipment in the vertical direction is not loaded, and the drainage capacity of the control equipment in the horizontal and vertical directions is loaded, and finally the horizontal and vertical drainage capacity conditions of the low flood sub-area are obtained.

[0143] Step S36: Based on the horizontal and vertical drainage capacity of the low-flood sub-area, the urban low-flood drainage grid sub-area is analyzed for the horizontal and vertical blocking and diagonal downward opening linkage drainage strategy, and the urban low-flood horizontal and vertical load blocking and diagonal downward opening linkage drainage strategy is generated to perform the corresponding urban low-flood load drainage optimization work.

[0144] In an embodiment of the present invention, by combining the horizontal and vertical drainage capacity conditions of the low flood sub-area obtained by previous analysis (including no load in both horizontal and vertical drainage, horizontal drainage load and no load in vertical, horizontal drainage no load and vertical load, and horizontal and vertical drainage load), the corresponding urban low flood drainage grid sub-area is analyzed for the linkage drainage strategy of the water pump control equipment in the corresponding direction, so as to adopt the corresponding drainage opening strategy according to the different drainage capacities of the horizontal and vertical water pump control equipment, so as to maximize the drainage efficiency of the existing drainage facilities, thereby improving the flood prevention capacity and disaster response capacity in the corresponding urban low flood drainage grid sub-area, and finally generating the urban low flood horizontal and vertical load closure and oblique opening linkage drainage strategy to perform the corresponding urban low flood load drainage optimization work.

[0145] Furthermore, the regional flood control drainage calculation formula in step S33 is specifically:

[0146] ;

[0148] The present invention obtains a regional flood control drainage calculation formula by using a specific mathematical model and after verification, which is used to perform drainage statistics calculation on the urban flood warning grid sub-area to be drained. The regional flood control drainage calculation formula considers in detail the influence of various factors on flood control drainage, including drainage network capacity, terrain slope, drainage time change and the contribution of drainage source, etc., wherein the drainage network capacity value determines the maximum capacity that can be drained per unit area, which is one of the bases for calculating the total drainage. The regional terrain slope value will affect the speed and flow direction of the water flow, and thus affect the drainage efficiency. The terrain slope value in the formula can be adjusted by the influence coefficient of the terrain slope on the drainage capacity. The drainage sensitivity index factor is a drainage sensitivity index factor, which is used to adjust the embodiment of the sensitivity of drainage in the overall formula. It can be adjusted according to the specific situation to reflect the sensitivity of drainage to changes in various factors. At the same time, the formula also considers the contribution value of the drainage source to analyze the change of the drainage source in time in the urban flood control drainage grid sub-area, and the drainage source will change its drainage over time. The contribution of different drainage sources to the total drainage is also distinguished by using specific weight coefficients of the drainage sources. Different drainage sources have different importance, which is expressed by In addition, the formula also introduces a correction factor for flood control drainage to correct and adjust the calculation results in practical applications, which can include the actual impact of various external conditions on drainage, such as equipment failure, human intervention, etc. By combining these factors, the regional flood control drainage calculation formula not only takes into account the basic drainage network capacity and terrain factors, but also takes into account time changes, the contribution of each drainage source and other correction factors, so as to more accurately evaluate and predict the flood control drainage needs of various areas of the city. This comprehensive consideration helps urban managers and flood control workers to formulate more accurate and effective flood control strategies and response measures based on actual conditions. Therefore, this formula fully takes into account the first Flood control drainage volume of each city flood control drainage grid sub-area , the total number of urban flood control and drainage grid sub-areas , the number of urban flood control and drainage grid sub-areas index parameters , No. The size of the area of ​​the flood control and drainage grid sub-area of ​​each city , No. The drainage network capacity value of each city flood control drainage grid sub-area , No. Regional terrain slope value of each urban flood control and drainage grid sub-area , the influence coefficient of terrain slope on drainage capacity , the influence coefficient of the drainage grid sub-area size on the drainage capacity , Discharge Sensitivity Index Factor , the total number of drainage sources in the urban flood control drainage grid sub-area , the number of drainage sources index parameter , No. The first in the urban flood control and drainage grid sub-area Drainage source at drainage time Drainage contribution value , No. The specific weight coefficient of drainage from each drainage source , No. Correction factor for flood control drainage , according to Flood control drainage volume of each city flood control drainage grid sub-area The correlation between the above parameters constitutes a functional relationship This formula can realize the statistical calculation process of the drainage volume of the grid sub-area to be discharged for urban flood warning. Correction factor for flood control drainage The introduction of can be adjusted according to the errors that occur in the calculation process, thereby improving the accuracy and applicability of the regional flood control drainage calculation formula.

[0149] Further, step S36 includes the following steps:

[0150] Step S361: When it is determined that the horizontal and vertical drainage capacity of the low flood sub-area is not loaded in both horizontal and vertical directions, the corresponding horizontal and vertical linkage downward drainage strategy in the urban low flood drainage grid sub-area is maintained to obtain the low flood horizontal and vertical downward drainage maintenance process;

[0151] In an embodiment of the present invention, if it is determined that the horizontal and vertical drainage capacity status of the low flood sub-area is that the drainage capacity in the horizontal and vertical directions is not loaded, the horizontal and vertical linkage downward drainage strategy in the area is maintained unchanged. This step confirms the drainage capacity status of the low flood drainage grid sub-area through field surveys or GIS technology. For example, in an urban drainage system, assuming that a specific area does not have serious waterlogging under current weather conditions, and its horizontal and vertical drainage capacities have not reached the load state, then the grid sub-area can maintain the current drainage strategy to maintain the horizontal and vertical linkage downward drainage process, thereby ensuring that the area maintains drainage efficiency under low flood conditions, and records the drainage process, and finally obtains the low flood horizontal and vertical downward drainage maintenance process.

[0152] Step S362: When it is determined that the horizontal and vertical drainage capacity of the low flood sub-area is horizontal drainage load and vertical no load, the flood control drainage pump control equipment in the horizontal direction of the urban low flood drainage grid sub-area is closed and the vertical direction is maintained. The flood control drainage pump control equipment in the oblique direction is opened, and the low flood horizontal closing and vertical maintenance oblique downward opening drainage process is obtained;

[0153] In an embodiment of the present invention, if it is determined that the drainage capacity status of the low-flood sub-area in the horizontal and vertical directions is that the drainage is loaded in the horizontal direction and not loaded in the vertical direction, it means that the drainage capacity of the flood control drainage pump control equipment in the horizontal direction of the low-flood drainage grid sub-area of ​​the city has reached the load state, but has not reached the load state in the vertical direction. In this case, the drainage pump control equipment in the horizontal direction of the area will be closed first, and the drainage pump control equipment in the vertical direction will continue to work. At the same time, the flood control drainage pump control equipment in the oblique direction will be opened to relieve the drainage pressure of the drainage pump in the horizontal direction to support the overall drainage operation, and the entire drainage process will be recorded, and finally the low-flood horizontal closure and vertical maintenance oblique downward opening drainage process will be obtained.

[0154] Step S363: When it is determined that the horizontal and vertical drainage capacity of the low flood sub-area is that the horizontal drainage is not loaded and the vertical drainage is loaded, the flood control drainage pump control equipment in the horizontal direction of the urban low flood drainage grid sub-area is maintained, the flood control drainage pump control equipment in the vertical direction is closed, and the flood control drainage pump control equipment in the oblique direction is opened, so as to obtain the low flood horizontal maintenance and vertical closing and oblique opening drainage process;

[0155] In an embodiment of the present invention, if it is determined that the drainage capacity status of the low-flood sub-area in the horizontal and vertical directions is that the drainage is not loaded in the horizontal direction and is loaded in the vertical direction, it means that the drainage capacity of the flood control drainage pump control equipment in the horizontal direction of the low-flood drainage grid sub-area of ​​the city has not reached the load state, but the load state has been reached in the vertical direction. In this case, the drainage pump control equipment in the horizontal direction of the area will be kept working, and the drainage pump control equipment in the vertical direction will be closed. At the same time, the flood control drainage pump control equipment in the oblique direction will be opened to relieve the drainage pressure of the vertical drainage pump to support the overall drainage operation, and the entire drainage process will be recorded, and finally the low-flood drainage process of maintaining the horizontal and vertical closure and oblique opening will be obtained.

[0156] Step S364: When it is determined that the horizontal and vertical drainage capacity of the low flood sub-area is equal to the horizontal and vertical drainage load, the flood control drainage pump control equipment in the horizontal and vertical directions of the urban low flood drainage grid sub-area is closed, and the flood control drainage pump control equipment in the oblique direction is opened, so as to obtain the low flood horizontal and vertical blocking and oblique downward opening drainage process;

[0157] In an embodiment of the present invention, if it is determined that the horizontal and vertical drainage capacity status of the low flood sub-area is that the horizontal and vertical drainage capacities are both under load, it means that the drainage capacity of the flood control drainage pump control equipment in the horizontal and vertical directions in the low flood drainage grid sub-area of ​​the city has reached the load state, and it is necessary to close the horizontal and vertical drainage pump control equipment in the area, and open the drainage pump control equipment in the oblique direction to ensure that the comprehensive drainage work can proceed smoothly. At the same time, the entire drainage process is recorded, and finally the low flood horizontal and vertical closure and oblique downward drainage process is obtained.

[0158] Step S365: Conduct drainage strategy linkage control analysis on the process of maintaining horizontal and vertical downward drainage in low flood conditions, the process of maintaining horizontal and vertical closure and diagonal downward drainage in low flood conditions, the process of maintaining horizontal and vertical closure and diagonal downward drainage in low flood conditions, and the process of horizontal and vertical blocking and diagonal downward drainage in low flood conditions, and generate a linkage drainage strategy for horizontal and vertical load blocking and diagonal downward opening in low flood conditions in the city, so as to perform corresponding urban low flood load drainage optimization work.

[0159] In an embodiment of the present invention, the drainage strategy is linked and controlled by the corresponding processing steps in the previously recorded low-flood horizontal and vertical downward drainage maintenance process, the low-flood horizontal closure and vertical maintenance oblique downward drainage process, the low-flood horizontal maintenance vertical closure and oblique downward drainage process, and the low-flood horizontal and vertical closure and oblique downward drainage process, so as to comprehensively consider the drainage capacity conditions in different grid sub-areas and weather forecasts and other factors, and formulate a comprehensive linkage drainage strategy for low-flood periods. For example, if a certain urban area has local heavy rainfall, the drainage equipment operation mode of each urban low-flood drainage grid sub-area will be automatically adjusted according to the real-time monitored horizontal and vertical drainage capacity conditions to maximize the drainage efficiency, thereby ensuring the stable operation of the urban drainage system under low-flood conditions, and finally generating a low-flood horizontal and vertical load closure and oblique downward linkage drainage strategy for the city, so as to perform corresponding optimization work of urban low-flood load drainage such as horizontal and vertical downward drainage, horizontal closure and vertical maintenance oblique downward drainage, horizontal maintenance and vertical closure and oblique downward drainage, and horizontal and vertical closure and oblique downward drainage, rather than just maintaining horizontal and vertical downward drainage.

[0160] Further, step S4 includes the following steps:

[0161] Step S41: performing upper adjacent drainage area identification analysis on the urban high flood drainage grid sub-area to obtain the upper adjacent drainage grid sub-area under the urban high flood situation;

[0162] In an embodiment of the present invention, the drainage areas with upper adjacent relationships are identified and analyzed for the previously determined urban high flood drainage grid sub-areas to identify and determine the adjacent relationships of each drainage grid sub-area, that is, to find out the upper adjacent areas of each area, so as to facilitate subsequent drainage capacity statistics and optimization decisions. For example, assuming that there is a drainage grid sub-area in the city during a high flood period, the upper adjacent areas of the grid sub-area are determined by using a geographic information system (GIS) and a mathematical modeling method, which involves map data processing and spatial analysis technology to ensure accurate identification of drainage grid sub-areas with adjacent relationships to the grid sub-area, and ultimately obtain drainage grid sub-areas with upper adjacent relationships during urban high flood conditions.

[0163] Step S42: Perform drainage capacity statistics analysis on the drainage grid sub-areas with adjacent relationships in each city under high flood conditions to obtain drainage capacity load statistics for the adjacent drainage areas in each city under high flood conditions;

[0164] In an embodiment of the present invention, a data statistical analysis method is used to collect and organize data related to the drainage capacity in the adjacent drainage grid sub-areas of each city under high flood conditions, such as the drainage pipe diameter, water pump power, natural drainage capacity, etc. of each area, and a statistical analysis of the drainage capacity of these data is performed to statistically calculate the statistical degree of drainage capacity load of each grid sub-area, that is, the drainage capacity of each area when dealing with high flood conditions, and finally obtain the drainage capacity load statistics of each city under high flood conditions.

[0165] Step S43: based on the drainage capacity load statistics of each urban high flood situation upper adjacent drainage area, the corresponding urban high flood situation upper adjacent drainage grid sub-area is subjected to drainage low load area screening processing to obtain the urban high flood situation upper adjacent drainage low load area;

[0166] In an embodiment of the present invention, by combining the drainage capacity load statistics of each urban high flood situation location adjacent drainage area obtained by previous quantitative calculation, the corresponding urban high flood situation location adjacent drainage grid sub-area is screened for low load areas to identify areas where the load of the pump control equipment is relatively low during the drainage process, thereby screening out areas with sufficient drainage capacity, and finally obtaining the urban high flood situation location adjacent drainage low load areas.

[0167] Step S44: Based on the upper adjacent drainage low-load area under the high flood situation in the city, the flood control drainage pump control equipment is used to analyze the upper diversion linkage drainage strategy for the urban high flood situation drainage grid sub-area, and the upper diversion linkage drainage strategy under the urban high flood situation is generated to perform the corresponding urban high flood situation diversion drainage optimization work.

[0168] In an embodiment of the present invention, flood control and drainage water pump control equipment is used to divert high flood water levels within a city's high flood drainage grid sub-area to a previously identified high flood location adjacent to a low-load drainage area for linkage drainage treatment, aiming to optimize the operation of the drainage system within the city's high flood drainage grid sub-area. Through precise diversion and linkage strategies, water flow can be effectively regulated to be diverted upward to areas with lower drainage load capacity, ensuring that the drainage capacity of high flood areas is utilized to the maximum extent, thereby automatically adjusting the working state of flood control and drainage water pump control equipment within the city's high flood drainage grid sub-area to achieve linkage drainage and ensure drainage efficiency and safety in the area. Finally, a diversion and linkage drainage strategy for high flood locations in the city is generated, thereby achieving diversion and drainage work within the corresponding high flood areas in the city.

[0169] Furthermore, the present invention also provides a smart flood control and drainage strategy analysis system based on a grid linkage mechanism, which is used to execute the smart flood control and drainage strategy analysis method based on a grid linkage mechanism as described above.
