[0029] Example 1

[0030] According to an embodiment of the present invention, a method embodiment for generating a floodplain disaster relief plan based on digital twins is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0031] Figure 1 This is a flowchart of an optional method for generating a watershed floodplain disaster relief plan based on digital twins according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0032] Step S102: Determine the corresponding floodplain area within the watershed based on the digital twin simulation model.

[0033] Optionally, the corresponding floodplain area within the watershed can be determined based on the system and electronic equipment. In this embodiment, the corresponding floodplain area within the watershed is determined based on the digital twin simulation model of the system.

[0034] Optional, such as Figure 2 As shown, the system collects and monitors elevation data, hydrological data, satellite imagery data, environmental monitoring data, and meteorological data of the watershed using its data monitoring equipment (e.g., radio wave current meters, turbidity meters, float-type water level meters, ultrasonic water level meters, electronic water gauges, and radar rain gauges). Then, a three-dimensional scene is built based on this data, a digital twin simulation model is generated from the scene, and finally, the corresponding floodplain area within the watershed is determined based on the digital twin simulation model.

[0035] Step S104: Determine the disaster risk level corresponding to the floodplain area based on the floodplain water flow rate.

[0036] In this embodiment, by analyzing the water flow in the floodplain area, an early warning is issued for river sections where the water level rises and reaches the floodplain warning level based on the analysis data. Then, based on the location information of the warning river section and the geographical data of the river section location information, the floodplain area range data is determined. The geographical information data of the floodplain range is extracted, and the disaster warning is reported. Based on the geographical information data of the floodplain, the path and direction of the floodplain are determined, and the floodplain risk level is divided according to the path of the floodplain, distinguishing different disaster risk levels. For example, the disaster risk level of the floodplain area is divided into low-risk area, medium-risk area, and high-risk area.

[0037] Step S106: Based on the disaster risk level corresponding to the floodplain area, determine the disaster relief plan corresponding to the floodplain area using a digital twin simulation model.

[0038] In this embodiment, different disaster relief plans are determined based on the disaster risk level corresponding to different floodplain areas. For example, when the disaster risk level corresponding to the floodplain area is high, an electronic evacuation notice is sent to the personnel, and the personnel in the area to be evacuated are located through mobile devices. The personnel in the area to be evacuated are then transferred to designated locations through mobile devices. Staff members count and report the number of people that can be accommodated in the resettlement area, and generate a list of supplies and plan the transportation route of supplies based on the number of people in the resettlement area and the location of the resettlement area. At the same time, a preventive reinforcement plan is implemented at key river sections of the floodplain to prevent the continuous spread of the floodplain.

[0039] Based on the scheme defined in steps S102 to S106 above, it can be understood that in this embodiment of the invention, the method of determining the corresponding disaster relief scheme by disaster risk level is adopted. The corresponding floodplain area in the watershed is determined by a digital twin simulation model; then, the disaster risk level corresponding to the floodplain area is determined based on the floodplain area water flow; finally, the disaster relief scheme corresponding to the floodplain area is determined based on the disaster risk level corresponding to the floodplain area by a digital twin simulation model.

[0040] It should be noted that determining the disaster risk level by using the water flow rate of the floodplain area improves the timeliness and accuracy of disaster risk level determination; determining the corresponding disaster relief plan based on the disaster risk level improves the timeliness and accuracy of disaster relief plan determination.

[0041] Therefore, the technical solution of this invention achieves the goal of determining the corresponding disaster relief plan based on the disaster risk level, thereby improving the timeliness and accuracy of disaster relief plan determination, and solving the technical problem in related technologies that it is impossible to quickly and accurately generate flood relief plans based on real-time conditions.

[0042] Furthermore, the system determines the disaster risk level of the floodplain area based on the floodplain water flow, including: monitoring real-time hydrological information, watershed environmental monitoring information, and meteorological data of the floodplain area, and obtaining the expected water flow of the floodplain area based on the water level-flow relationship obtained by analyzing historical hydrological information; determining the floodplain water flow based on the expected water flow; then determining the safe threshold and dangerous threshold for water flow based on historical hydrological information, wherein the safe threshold for water flow is less than the dangerous threshold for water flow; comparing the floodplain water flow with the safe threshold and dangerous threshold for water flow to obtain the comparison result; and finally determining the disaster risk level of the floodplain area based on the comparison result.

[0043] Optionally, the safe water flow threshold indicates that the risk of flooding is extremely low when the water flow is below this threshold; the dangerous water flow threshold indicates that the risk of flooding is extremely high when the water flow is above this threshold. The safe and dangerous water flow thresholds can be calculated based on historical water flow data. The projected water flow is calculated by analyzing the water level-flow relationship obtained from historical water flow data, real-time water level information, watershed environmental monitoring information, and real-time meteorological information. The accuracy of the projected water flow data calculation is verified using real-time hydrological information, and the calculated parameters are continuously updated.

[0044] Optionally, the floodwater flow rate of the monitored floodplain area can be compared with the safe and dangerous thresholds for water flow to determine the disaster risk level of the floodplain area. For example, if the floodwater flow rate of the floodplain area is less than the safe threshold for water flow, the disaster risk of flooding is extremely low, and the disaster risk level can be determined as low risk.

[0045] It should be noted that the safety threshold and danger threshold for water flow are determined based on historical hydrological information. The disaster risk level is determined by comparing the water flow in the floodplain with the safety threshold and danger threshold. This improves the timeliness and accuracy of disaster risk level determination and prepares the corresponding emergency response plan based on the disaster risk level. This further improves the timeliness and accuracy of generating floodplain disaster relief plans.

[0046] Furthermore, the system determines the disaster risk level of the floodplain area based on the comparison results. Specifically, when the water flow in the current floodplain area is less than the safe water flow threshold, the disaster risk level of the current floodplain area is determined to be the first risk level; when the water flow in the current floodplain area is greater than or equal to the safe water flow threshold but less than the dangerous water flow threshold, the disaster risk level of the current floodplain area is determined to be the second risk level; when the water flow in the current floodplain area is greater than or equal to the dangerous water flow threshold, the disaster risk level of the current floodplain area is determined to be the third risk level. The first risk level is lower than the second risk level, and the second risk level is lower than the third risk level.

[0047] Optionally, when the regional water flow in the current floodplain area is less than the safe water flow threshold, the disaster risk level of the current floodplain area is determined to be Level 1, where the risk of disaster occurrence corresponding to Level 1 is extremely low and can be defined as low risk. When the regional water flow in the current floodplain area is greater than the dangerous water flow threshold, the disaster risk level of the current floodplain area is determined to be Level 3, where the risk of disaster occurrence corresponding to Level 3 is extremely high, i.e., floodplain disaster will definitely occur, and can be defined as high risk. When the regional water flow in the current floodplain area is between the safe water flow threshold and the dangerous water flow threshold, i.e., the regional water flow is greater than the safe water flow threshold but less than the dangerous water flow threshold, the disaster risk level of the area is determined to be Level 2. Therefore, Level 2 risk falls between low and high risk, and can thus be defined as medium risk.

[0048] It should be noted that by comparing the regional water flow in the floodplain with the safe and dangerous water flow thresholds to determine the disaster risk level, the timeliness and accuracy of disaster risk level determination are improved, further enhancing the timeliness and accuracy of generating floodplain disaster relief plans.

[0049] In an optional embodiment, the system can also determine a disaster relief plan corresponding to the floodplain area based on the disaster risk level corresponding to the floodplain area. Specifically, when the disaster risk level of the current floodplain area is the first risk level or the second risk level, the system analyzes the floodplain locations corresponding to the current floodplain area using a digital twin simulation model to determine at least one floodplain path; generates at least one floodplain water diversion plan based on the at least one floodplain path; determines the material consumption data, diversion plan cost data, and diversion plan consumption time information corresponding to the at least one floodplain water diversion plan; determines a target diversion plan from the at least one floodplain water diversion plan based on the material consumption data, diversion plan cost data, and diversion plan consumption time information; and determines a disaster relief plan based on the target diversion plan.

[0050] In this embodiment, when the disaster risk level of the current floodplain area is either the first risk level or the second risk level, i.e., the disaster risk level of the current floodplain area is low risk or medium risk, the floodplain points corresponding to the current floodplain area are analyzed through a digital twin simulation model to determine at least one floodplain path. The specific steps for determining the floodplain water diversion scheme based on at least one floodplain path are as follows:

[0051] Step 11: Calculate the materials required for the floodplain water diversion plan and estimate the time required for material allocation.

[0052] Step 12: Extract the area information through which the floodplain water diversion plan passes, determine whether the corresponding floodplain area involves residents, industrial areas, or farmland, and calculate the loss cost for people and things in the affected areas; generate the diversion plan loss factor based on the loss cost calculation results, and determine the material consumption data corresponding to the floodplain water diversion plan based on the diversion plan loss factor.

[0053] Step 13: Calculate the material (material cost for blocking and diverting) and manpower costs involved in the floodplain water diversion plan through the material allocation plan, generate the diversion plan cost factor, and determine the diversion plan cost data corresponding to the floodplain water diversion plan based on the diversion plan cost factor.

[0054] Step 14: Calculate the workload of dredging and floodplain blocking to generate the time factor of the dredging plan, and determine the time consumption information of the dredging plan corresponding to the floodplain water flow dredging plan based on the time factor of the dredging plan.

[0055] Step 15: Determine the target dredging scheme from multiple floodplain dredging schemes by using material consumption data, dredging scheme cost data, and dredging scheme consumption time information.

[0056] Step 16: Determine the final disaster relief plan based on the target evacuation plan.

[0057] Optionally, by using parameters such as the loss factor, cost factor, and time factor of the diversion plan, the diversion plan for the floodplain can be simulated and transformed into a visual plan, which can then be sent to management personnel as a decision-making aid.

[0058] It should be noted that by determining floodwater diversion schemes based on disaster risk levels, and by utilizing data on material consumption, cost, and time required for each scheme, the timeliness and accuracy of generating floodwater relief plans are further improved. By creating visualized floodwater diversion schemes through simulation, methods to mitigate floodwater spread are identified through continuous simulations, thereby controlling the flow of floodwater and improving the timeliness and accuracy of floodwater relief plan generation, ultimately reducing floodwater losses.

[0059] Furthermore, before analyzing the floodplain locations corresponding to the current floodplain area through a digital twin simulation model to determine at least one floodplain path, the system acquires elevation data, satellite imagery, and environmental data of the floodplain area's watershed. Based on the elevation data, it extracts topographic data. A three-dimensional scene model of the floodplain watershed is generated. Satellite imagery and topographic data are processed to generate an initial model of the floodplain watershed. Finally, a digital twin simulation model is generated based on the initial model, the three-dimensional scene model, and the environmental data.

[0060] Optionally, the elevation data includes watershed topographic data and watershed infrastructure information for the floodplain area. A 3D scene is constructed using the collected elevation data and satellite imagery, and then a digital twin simulation model is generated based on the 3D scene. The specific steps are as follows:

[0061] Step 21: Extract elevation data to obtain watershed topographic data and watershed facility information for the floodplain area.

[0062] Step 22: Generate a detailed 3D scene model of the floodplain area based on the watershed elevation data.

[0063] Step 23: Based on the satellite imagery information corresponding to the watershed and the extracted watershed topographic data, perform stitching processing to generate the initial watershed model of the floodplain area.

[0064] Step 24: Generate a digital twin simulation model of the initial model of the floodplain area watershed, the three-dimensional scene model of the floodplain area watershed, and the facility information of the floodplain area watershed.

[0065] Furthermore, the system analyzes the floodplain locations corresponding to the current floodplain area using a digital twin simulation model to determine at least one floodplain path. This includes: determining at least one initial floodplain path corresponding to the current floodplain area based on the terrain data of the floodplain locations in the current floodplain area using the digital twin simulation model; and then adjusting the low-lying locations in the at least one initial floodplain path based on the water flow rate and velocity of the at least one initial floodplain path to obtain at least one floodplain path.

[0066] Optionally, the system analyzes the floodplain locations corresponding to the current floodplain area using a digital twin simulation model to determine at least one floodplain path. The specific steps are as follows:

[0067] Step 31: By locating the floodplain area in the current floodplain region, the main flow path of the floodplain is calculated based on hydrodynamic simulation, and the low-lying terrain data within the relative range is extracted to determine at least one initial floodplain path.

[0068] Step 32: Determine whether there are any usable (i.e., divertable) lakes or rivers within the current floodplain area, and extract the lake and river data information;

[0069] Step 33: Dynamically simulate and extrapolate the initial floodplain path based on the water flow rate and velocity within the floodplain area in the current floodplain region.

[0070] Step 34: Adjust the low-lying points in the initial floodplain path, simulate filling and raising the low-lying points in the floodplain path, and perform water flow simulation after the blocking points are blocked to deduce the new floodplain path.

[0071] Step 35: If the flooding effect of the water flow does not change significantly after the blockage point is blocked, the terrain of the nearest blockage point is changed to deduce the new direction of the floodwater flow and determine a flood path. For example, the direction and path of the water flow can be changed by filling in the low-lying area or increasing its elevation.

[0072] It should be noted that by adjusting the low-lying points in at least one initial floodplain path based on the water flow rate and velocity of at least one initial floodplain path, at least one floodplain path is obtained, which improves the accuracy of floodplain path determination and prepares for the subsequent accurate generation of disaster relief plans.

[0073] Furthermore, the system generates at least one floodplain flow diversion scheme based on at least one floodplain path, including: determining the floodplain flow diversion scheme corresponding to at least one floodplain path according to the distance between the floodplain points in at least one floodplain path and the target river, wherein the target river is a river, lake, etc. that can be diverted.

[0074] Optionally, after changing the original path of the water flow, the water flow will seek a new direction, and the water flow of the floodplain can be guided. During the water flow guidance process, at least one floodplain water flow diversion scheme corresponding to the floodplain path is determined based on the distance between the floodplain point and the target river in at least one floodplain path. For example, the floodplain water flow diversion path is planned based on the distance extracted from the floodplain point to the river or lake that can be diverted, and about 1-3 diversion schemes are planned.

[0075] Alternatively, the system determines the disaster relief plan corresponding to the floodplain area based on the disaster risk level of the floodplain area. This includes: obtaining the number and location information of the affected objects in the current floodplain area when the disaster risk level of the current floodplain area is level three; then determining the resettlement area for the affected objects based on the number and location information; determining the material information of disaster relief supplies based on the number of affected objects in the resettlement area; generating the transportation route of disaster relief supplies based on the resettlement area, the number of affected objects in the resettlement area, and the material information of the disaster relief supplies; and finally generating a disaster relief plan based on the material information of the disaster relief supplies and the transportation route.

[0076] In this embodiment, when the disaster risk level of the current floodplain area is level three, i.e., high risk, the first step is to evacuate people from the high-risk area. The specific steps are as follows:

[0077] Step 41: Obtain the list of disaster victims in the risk area based on the location information, and use the geographic data, the list of disaster victims and GPS location to index and obtain the nearest resettlement area for the corresponding disaster victim.

[0078] Step 42: Based on the distance between the disaster victims and the resettlement area, the information of the resettlement area is published to the communication devices of the disaster victims through the operator;

[0079] Step 43: Using GPS positioning technology of mobile communication devices, the disaster victims that need to be transferred are located in real time to determine whether all disaster victims have been transferred.

[0080] Step 44: Disaster victims who have not been evacuated in time will be transferred and assigned to designated locations by the nearest disaster relief workers.

[0081] Step 45: After the personnel resettlement and transfer are completed, report the completion of the personnel transfer to the system.

[0082] Furthermore, the number of disaster victims in the resettlement area is counted to determine the material information for disaster relief supplies. The specific steps are as follows:

[0083] Step 51: Match supplies to disaster victims in different resettlement areas based on their quantity;

[0084] Step 52: Based on the rules for basic living supplies, generate a supply allocation list by allocating information on essential supplies such as water and food.

[0085] Step 53: Submit the generated material allocation list to the resettlement area management personnel for confirmation of the material allocation list;

[0086] Step 54: After confirming that the material allocation list is correct, send the material allocation list to the person in charge of distributing disaster relief and resettlement materials.

[0087] Furthermore, based on the resettlement area, the number of disaster victims within the resettlement area, and the information on the relief supplies, transportation routes for the relief supplies are generated, and the relief supplies are allocated and distributed. The specific steps are as follows:

[0088] Step 61: The staff responsible for distributing disaster relief and resettlement materials will prepare the materials according to the disaster relief material list. Once the disaster relief materials are prepared, they will report the completion of the preparation information through mobile communication devices.

[0089] Step 62: After receiving feedback that the supplies are ready, the system automatically allocates vehicles for transporting disaster relief supplies.

[0090] Step 63: The system automatically generates a transportation route based on the quantity and resettlement area in the disaster relief supplies list;

[0091] Step 64: The system automatically dispatches relief material transport vehicles based on the nearest location to the relief material storage point.

[0092] Step 65: The system automatically notifies the transport personnel to carry out the task of transporting disaster relief supplies based on the allocation of transport vehicles.

[0093] Step 66: After completing the transportation task, the transportation personnel report the completion of the transportation task through mobile communication devices, and carry out the allocation and distribution of disaster relief materials to complete the disaster relief plan.

[0094] It should be noted that by generating transportation routes for disaster relief supplies based on the resettlement area, the number of disaster victims within the resettlement area, and the information on the disaster relief supplies, and by generating disaster relief plans based on the information on the disaster relief supplies and transportation routes, the timeliness and accuracy of generating flood flood relief plans have been improved.

[0095] Furthermore, after determining the disaster risk level of the floodplain area based on the comparison results, the system also includes: obtaining the review results of the review object's review of the disaster risk level of the floodplain area after determining the disaster risk level of the floodplain area based on the comparison results; and determining whether to adjust the disaster risk level and disaster relief plan of the floodplain area based on the review results.

[0096] Optionally, after determining the disaster risk level of the floodplain area based on the comparison results, the data on the classified disaster risk level, the assessment criteria, and the rules to be implemented in the watershed areas of different risk levels are reviewed and confirmed by the management personnel, and a record notification is generated. Based on the review results, it is determined whether to adjust the disaster risk level and disaster relief plan of the floodplain area.

[0097] Optionally, information can be released and notified based on the risk level of the designated area, and the information can be released simultaneously through multiple channels such as mobile communication devices, television stations, computers, and radio. Mobile communication devices can release early warning information simultaneously via SMS notifications from operators.

[0098] Therefore, this invention provides a novel method for generating floodplain disaster relief plans based on digital twins. This method monitors floodplain water flow and velocity, performs hydrodynamic simulation, and uses the simulation to preprocess and extrapolate impending disasters. Through continuous simulation, it seeks solutions to floodplain spread, diverts water flow in the floodplain area, reduces floodplain losses, and thus improves the accuracy of floodplain disaster relief plan generation.

[0099] Example 2

[0100] According to an embodiment of the present invention, an embodiment of a watershed floodplain disaster relief plan generation device based on digital twin is also provided, wherein, Figure 3 This is a schematic diagram of an optional digital twin-based floodplain disaster relief scheme generation device according to an embodiment of the present invention, such as...
