Description

Technical Field

[0001] This application relates to the field of Internet technology, and in particular to a method and system for urban operation event consultation and scheduling based on two-dimensional and three-dimensional integration. Background Technology

[0002] Traditional consultations and coordination for urban operational events typically rely on PowerPoint presentations, using paper and two-dimensional materials. However, these materials suffer from drawbacks such as difficulty in updating data and low transmission efficiency when depicting urban layouts, road systems, and building locations. They fail to realistically recreate on-site scenarios, retrieve and analyze key data in real time, and comprehensively represent the situation during decision-making. This results in limited information presentation, poor data sharing, insufficient communication and collaboration, and inadequate decision support, leading to low consultation efficiency in urban emergency management.

[0005] To achieve the above objectives, this application provides a method for urban operation event consultation and scheduling based on two-dimensional and three-dimensional integrated methods, the method comprising: Receive real-time event information within the city, and automatically locate the location on a pre-constructed digital twin base map of the city information model based on the geographic location data in the real-time event information; Using the geographic location data as the center of the event point, the system automatically associates and merges the two-dimensional and three-dimensional static data and dynamic perception data within a preset range around the center of the event point, and generates a two-dimensional and three-dimensional integrated visualization consultation scene focusing on the event information based on the pre-constructed digital twin base map of the urban information model, the two-dimensional and three-dimensional static data and the dynamic perception data. In response to user operation, operation information is generated. Based on the operation information, a handling plan matching the event information is retrieved. The handling plan is then visualized and simulated in the two-dimensional integrated visualization consultation scenario to obtain the simulation result.

A base map layer is generated by overlaying the two-dimensional static data onto the pre-constructed digital twin base map of the city information model based on the location information; The three-dimensional static data is superimposed on the base map layer to obtain a three-dimensional map layer; The dynamic sensing data and the three-dimensional map layer are fused based on the location information to obtain a three-dimensional dynamic map layer; The three-dimensional dynamic map layer is visualized and rendered to obtain a two-dimensional and three-dimensional integrated visualization consultation scene focusing on the event information.

[0008] In one embodiment, the steps of generating operation information in response to user operation, retrieving a contingency plan matching the event information based on the operation information, and visually simulating the contingency plan in the integrated 2D / 3D visualization consultation scenario to obtain the simulation result include: In response to user operation, operation information is generated. When the operation information is to invoke a contingency plan, one or more contingency plans are matched and retrieved from the contingency plan library based on the type, level and key attributes of the real-time event information. The contingency plan text information and structured data are loaded into the two-dimensional integrated visualization consultation scenario. The structured data includes contingency resources, action routes, and key nodes. The structured data in the contingency plan is automatically associated and mapped with the spatial elements in the two-dimensional integrated visualization consultation scene. The contingency resources are bound to the corresponding models in the two-dimensional integrated visualization consultation scene. The action route is planned and visualized in three dimensions in the two-dimensional integrated visualization consultation scene. The key nodes are marked with three-dimensional icons in the two-dimensional integrated visualization consultation scene. Based on the scheduling instructions of the operation information, the handling plan in the integrated two-dimensional and three-dimensional visualization consultation scenario is visualized and simulated to obtain the simulation results.

[0009] In one embodiment, the step of using the scheduling instruction based on the operation information to perform a visual simulation of the contingency plan in the integrated 2D / 3D visualization consultation scenario and obtain the simulation result includes: When the number of the two-dimensional integrated visualization consultation scenarios is greater than the preset number, visualization simulations are performed on different two-dimensional integrated visualization consultation scenarios to obtain the corresponding initial simulation results. A feasibility assessment is performed on the initial simulation results to obtain the corresponding feasibility score; The initial simulation result corresponding to the highest feasibility score in the feasibility score is output as the simulation result.

[0010] In one embodiment, before the step of visually simulating the contingency plan in the two-dimensional integrated visualization consultation scenario based on the scheduling instruction of the operation information to obtain the simulation result, the method further includes: Upon receiving frontline data from the frontline execution terminal, environmental impact parameters are generated based on the frontline data. The integrated 2D / 3D visualization consultation scenario is updated based on the environmental impact parameters.

[0011] In one embodiment, the step of generating scheduling decision information based on the simulation results and distributing the scheduling decision information to the front-line execution terminal includes: The simulation results are analyzed to obtain the estimated handling time, resource adequacy, and risk points of the plan; Based on the estimated processing time, the resource adequacy, and the risk points of the plan, determine the resource allocation plan, action route planning, and task time nodes; Based on the resource allocation plan, the action route plan, and the task time nodes, scheduling decision information is generated; The scheduling decision information is then sent to the front-line execution terminals.

[0012] In one embodiment, the step of generating scheduling decision information based on the resource allocation plan, the action route planning, and the task time nodes includes: The resource allocation plan, the action route planning, and the task time nodes are mapped to the two-dimensional integrated visualization consultation scenario to generate a visualization scheduling plan. The visualization scheduling plan is then sent to the user display terminal so that the user can generate adjustment instructions based on the visualization scheduling plan displayed on the user display terminal. The system receives adjustment instructions generated based on the visual scheduling scheme, updates the visual scheduling scheme and sends it to the user display terminal until it receives a confirmation instruction from the user display terminal, and then generates scheduling decision information based on the updated visual scheduling scheme.

[0013] In one embodiment, the step of receiving real-time event information within the city and automatically locating the location on a pre-constructed digital twin base map of the city information model based on the geographic location data in the real-time event information includes: Receive real-time event information within the city, parse the real-time event information, and determine the geographical location data of the real-time event information; The geographic location data is standardized and converted to the same spatial coordinate system as the pre-constructed digital twin base map of the urban information model to obtain standardized geographic location information. Spatial matching is performed between the standardized geographic location information and the pre-built digital twin base map of the urban information model to enable the event information to be automatically located in the pre-built digital twin base map of the urban information model.

[0014] Furthermore, to achieve the above objectives, this application also proposes a two-dimensional integrated urban operation event consultation and dispatch system, which includes: The event awareness module is used to receive real-time event information within the city and automatically locate events in a pre-built digital twin base map of the city information model based on the geographic location data in the event information. The scene construction module is used to automatically associate and fuse two-dimensional and three-dimensional static data and dynamic perception data within a preset range around the event point center, with the geographical location data as the event point center, and generate a two-dimensional and three-dimensional integrated visualization consultation scene focusing on the event information based on the pre-built digital twin base map of the urban information model, the two-dimensional and three-dimensional static data and the dynamic perception data. The event response module is used to generate operation information in response to user operations, retrieve the handling plan that matches the event information based on the operation information, and perform a visual simulation of the handling plan in the two-dimensional integrated visualization consultation scenario to obtain the simulation result. The consultation and scheduling module is used to generate scheduling decision information based on the simulation results and to send the scheduling decision information to the front-line execution terminal.

[0015] In addition, to achieve the above objectives, this application also proposes a two-dimensional integrated urban operation event consultation and scheduling device, which includes: a memory, a processor, and a computer program stored in the memory and executable on the processor. The computer program is configured to implement the steps of the two-dimensional integrated urban operation event consultation and scheduling method described above.

[0016] In addition, to achieve the above objectives, the present invention also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, it implements the steps of the urban operation event consultation and scheduling method based on two-dimensional and three-dimensional integration as described above.

[0017] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the urban operation event consultation and scheduling method based on two-dimensional and three-dimensional integration as described above.

[0018] This application provides a method for urban operation event consultation and scheduling based on integrated 2D and 3D data. It automatically locates events on a digital twin base map and integrates surrounding 2D and 3D dynamic and static data to quickly construct an integrated visual scene, solving the pain points of information dispersion and time-consuming integration, and greatly improving situational awareness efficiency. Next, the method simulates and extrapolates contingency plans within the visualized scene, transforming abstract text into an intuitive dynamic process, enabling decision-makers to quickly assess the feasibility of plans and predict risks, thus improving the efficiency of plan analysis and decision-making. Finally, the optimized decisions generate structured instructions for issuance and execution tracking, forming a closed loop from analysis and decision-making to execution. This reduces communication layers and information distortion, thereby shortening the overall emergency response time and significantly improving consultation efficiency. Attached Figure Description

[0022] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0023] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0024] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The main solution of this application embodiment is: to receive real-time event information within the city and, based on the geographical location data in the real-time event information, to automatically locate the location in a pre-built digital twin base map of the city information model; Using the geographic location data as the center of the event point, the system automatically associates and merges the two-dimensional and three-dimensional static data and dynamic perception data within a preset range around the center of the event point, and generates a two-dimensional and three-dimensional integrated visualization consultation scene focusing on the event information based on the pre-constructed digital twin base map of the urban information model, the two-dimensional and three-dimensional static data and the dynamic perception data. In response to user operation, operation information is generated. Based on the operation information, a handling plan matching the event information is retrieved. The handling plan is then visualized and simulated in the two-dimensional integrated visualization consultation scenario to obtain the simulation result. Based on the simulation results, scheduling decision information is generated and sent to the front-line execution terminals for consultation and scheduling of urban operation events.

[0026] Currently, traditional consultations and coordination for urban operational events are typically conducted via PowerPoint presentations, relying on paper and two-dimensional materials. However, using these materials to depict urban layouts, road systems, and building locations suffers from drawbacks such as difficulty in updating data and low transmission efficiency. The inability to realistically recreate on-site scenarios, retrieve and analyze key data in real time, and comprehensively represent the situation during decision-making limits information presentation, hinders data sharing, and impedes communication, collaboration, and decision support, resulting in low consultation efficiency during urban emergency management.

[0027] This application provides a solution that automatically locates events on a digital twin base map and integrates surrounding 2D and 3D dynamic and static data to quickly construct an integrated visual scene. This solves the pain points of scattered information and time-consuming integration, greatly improving situational awareness efficiency. Next, contingency plans are simulated and extrapolated within the visualized scene, transforming abstract text into an intuitive dynamic process. This allows decision-makers to quickly assess the feasibility of contingency plans and predict risks, improving the efficiency of plan analysis and decision-making. Finally, the optimized decisions generate structured instructions for issuance and execution tracking, forming a closed loop from analysis and decision-making to execution. This reduces communication layers and information distortion, thereby shortening overall emergency response time and significantly improving consultation efficiency.

[0028] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device capable of performing the above functions, such as a two-dimensional integrated urban operation event consultation and scheduling device. This embodiment does not specifically limit it in this regard. The following uses a two-dimensional integrated urban operation event consultation and scheduling device as an example to describe this embodiment and the following embodiments.

[0029] All actions involving the acquisition of signals, information, or data in this application are carried out in accordance with the relevant data protection laws and policies of the country where the application is located, and with the authorization of the owner of the relevant device.

[0030] This application provides a method for urban operation event consultation and scheduling based on a two-dimensional and three-dimensional integrated system, referring to... Figure 1 , Figure 1This is a flowchart illustrating the first embodiment of the urban operation event consultation and scheduling method based on two-dimensional and three-dimensional integration in this application.

[0031] In this embodiment, the urban operation event consultation and scheduling method based on two-dimensional and three-dimensional integration includes steps S10 to S40: Step S10: Receive real-time event information within the city, and automatically locate the location on the pre-constructed digital twin base map of the city information model based on the geographical location data in the real-time event information.

[0032] It should be noted that real-time event information refers to event data generated in real time during the operation of the city, such as traffic accidents, public safety incidents, infrastructure failures, and social activities. This information is obtained through various channels, including IoT sensors, surveillance cameras, social media platforms, and reports from lower-level departments. Geographic location data refers to the key data in real-time event information used to identify the location of events. This can be represented by precise coordinates such as latitude and longitude, or by vague descriptions such as a specific street or section, or by district numbering. The pre-built city information model is a virtual digital model based on the city's physical entities, while the part representing city details is a digital twin base map. This can include static urban elements such as roads, buildings, pipelines, and terrain, and can also support the overlay of other external data, featuring real-time updates.

[0033] In the implementation, real-time event information is received through the data access layer. After receiving the information, it is parsed to extract key fields, including event type, timestamp, and geographic location data. If the geographic location data is not in a standard format, it can be converted to a standard format. For example, if the standard format is latitude and longitude information, and the received text information is "a building on a certain road," then the text-based geographic location information can be converted into latitude and longitude format. After determining the geographic location information, it can be spatially matched with a pre-built digital twin base map. Using the SDK or API provided by the base map, the event location can be automatically mapped to the specific location on the base map, and visual markers can be generated, achieving automatic location of real-time event information.

[0034] In one feasible implementation, the step of receiving real-time event information within the city and automatically locating the location on a pre-constructed digital twin base map of the city information model based on the geographic location data in the real-time event information includes: Receive real-time event information within the city, parse the real-time event information, and determine the geographical location data of the real-time event information; The geographic location data is standardized and converted to the same spatial coordinate system as the pre-constructed digital twin base map of the urban information model to obtain standardized geographic location information. Spatial matching is performed between the standardized geographic location information and the pre-built digital twin base map of the urban information model to enable the event information to be automatically located in the pre-built digital twin base map of the urban information model.

[0035] In practical implementation, a large amount of real-time data exists within the city. Consultation is used to address significant, urgent, and essential public events, such as large-scale multi-vehicle collisions, urban flooding requiring rescue, or widespread public health emergencies. Various platforms typically collect and disseminate this information. Regardless of the data source, the first step is preliminary verification to confirm the event's occurrence. If it has, the consultation mechanism is activated to begin preparing for the allocation of urban resources. First, the real-time event information needs to be analyzed to determine its geographic location data. Then, the geographic location data is standardized, using the coordinate format of a digital twin base map as a benchmark. The location information is converted to the spatial coordinate system of the digital twin base map, resulting in standardized geographic location information. This standardized geographic location information is then used as a query point on the pre-built digital twin base map of the city information model. Geographic elements with matching coordinates in the query results are identified as target locations and visualized, achieving automatic positioning.

[0036] Step S20: Using the geographic location data as the event point center, automatically associate and fuse the two-dimensional and three-dimensional static data and dynamic perception data within a preset range around the event point center, and generate a two-dimensional and three-dimensional integrated visualization consultation scene focusing on the event information based on the pre-constructed urban information model digital twin base map, the two-dimensional and three-dimensional static data and the dynamic perception data.

[0037] It should be noted that the event center point refers to the precise geographical coordinates of the event location on the digital twin base map after analysis and standardization. Two-dimensional static data refers to basic geographic information data based on maps, such as administrative boundaries, road networks, rivers and lakes, and land use types. These typically exist in the form of vector surfaces, lines, and points. Three-dimensional static data includes detailed internal and external structural information of individual buildings, topographic features, etc. Dynamic sensing data is data sensed and transmitted in real-time or near real-time through IoT devices, reflecting the current state of urban operations, such as traffic flow data and pedestrian flow data. The integrated two-dimensional and three-dimensional visualization consultation scenario refers to a highly integrated visualization environment dynamically generated for emergency command and collaborative decision-making.

[0038] In the specific implementation, refer to Figure 2 , Figure 2 This is a schematic diagram of an event on a city's digital twin base map. This example uses a restaurant kitchen explosion causing multiple injuries as a simple illustration. The location of this event can be represented by a pentagram on the base map. Responding to this event requires the immediate deployment of police resources to maintain order; the deployment of medical resources to create a green channel for medical personnel to promptly transport the injured; and the deployment of fire-fighting resources to extinguish the fire and control its spread and secondary explosion damage. In the diagram, four-pointed stars represent police departments, triangles represent fire departments, and pentagons represent medical departments with rescue capabilities. Different colors on roads indicate the level of congestion on those sides. The dashed circle represents a preset radius around the event's center. If this radius is insufficient to adequately handle the event, the radius can be adaptively expanded until the event can be properly managed. This allows for the acquisition of available resources within the region, including their location information. For the location of an incident, three-dimensional data can be determined, facilitating firefighters' rescue of the injured and control of the fire. Dynamic sensing data such as traffic flow and pedestrian flow can be used by traffic management departments to adjust street traffic lights, clear rescue routes, and reduce rescue time. When this data is aggregated, it forms a unified two-dimensional and three-dimensional visualization consultation scenario focused on the current event information.

[0039] In one feasible implementation, the step of automatically associating and fusing two-dimensional and three-dimensional static data and dynamic sensing data within a preset range around the event point center, using the geographic location data as the event point center, and generating a two-dimensional and three-dimensional integrated visualization consultation scene focusing on the event information based on the pre-constructed urban information model digital twin base map, the two-dimensional and three-dimensional static data, and the dynamic sensing data includes: Determine the event type and event level of the real-time event information, determine the data association range based on the event type and event level, and use the data association range as a preset range; Based on the event point center and the preset range, retrieve and load two-dimensional static data and three-dimensional static data within the preset range from the integrated two-dimensional and three-dimensional spatial database; Retrieve dynamic sensing data within the preset range; The two-dimensional static data, the three-dimensional static data, the dynamic perception data, and the pre-constructed digital twin base map of the urban information model are fused in a unified coordinate system to obtain a two-dimensional and three-dimensional integrated visualization consultation scene focusing on the event information.

[0040] In practical implementation, when parsing real-time event information, the event type and event level can be obtained. Event types include traffic accidents, fires, and mass incidents, while event levels include general, relatively large, serious, and extremely serious. Different data can be mapped to specific spatial range parameters, thereby determining the event type and event level of the real-time event information. Different types of event types and event levels correspond to different data association ranges, which are defined as preset ranges. Then, with the event point center as the center and the preset range as the radius, the 2D and 3D integrated spatial database within the defined area is retrieved and loaded, along with dynamic sensing data within the defined range. Finally, the 2D static data, 3D static data, and dynamic sensing data are fused using a unified coordinate system on a pre-constructed digital twin base map of the urban information model to obtain a 2D / 3D integrated visual consultation scene focused on the current real-time event.

[0041] In one feasible implementation, the step of performing unified coordinate fusion of the two-dimensional static data, the three-dimensional static data, the dynamic sensing data, and the pre-constructed digital twin base map of the urban information model to obtain a two-dimensional and three-dimensional integrated visualization consultation scene focusing on the event information includes: The location information of the two-dimensional static data, the three-dimensional static data, and the dynamic sensing data are respectively unified into the coordinate system of the pre-constructed digital twin base map of the urban information model, and the location information is aligned. A base map layer is generated by overlaying the two-dimensional static data onto the pre-constructed digital twin base map of the city information model based on the location information; The three-dimensional static data is superimposed on the base map layer to obtain a three-dimensional map layer; The dynamic sensing data and the three-dimensional map layer are fused based on the location information to obtain a three-dimensional dynamic map layer; The three-dimensional dynamic map layer is visualized and rendered to obtain a two-dimensional and three-dimensional integrated visualization consultation scene focusing on the event information.

[0042] In its implementation, the first step is to uniformly register the location information of all source data, including 2D static, 3D static, and dynamically perceived data, to the spatial reference system used by the digital twin base map through spatial coordinate transformation, ensuring spatial consistency. Next, in the visualization engine, using the digital twin base map as a foundation, 2D static data is overlaid using vector rendering technology to form a basic map layer. On this basis, 3D static data such as buildings and terrain are integrated by loading 3D model tiles to construct a 3D map layer with a three-dimensional spatial structure. Then, through spatiotemporal correlation and dynamic data binding technologies, real-time streaming data is mapped to the corresponding spatial location in the 3D map layer, and dynamic visualization is achieved using icons, particle effects, or data-driven styles, forming a 3D dynamic map layer. Finally, relying on the real-time rendering capabilities of the graphics engine, the 3D dynamic map layer is visualized and rendered, and interactive controls and multi-terminal synchronization protocols are integrated to ultimately generate an event-focused, integrated 2D / 3D visualization consultation scenario that supports multi-view switching, real-time data updates, and collaborative operations.

[0043] Step S30: In response to user operation, operation information is generated. Based on the operation information, a handling plan matching the event information is retrieved. The handling plan is then visualized and simulated in the two-dimensional integrated visualization consultation scenario to obtain the simulation result.

[0044] It should be noted that the operational information is the control information that converts user input commands into control information to control the simulation process. The contingency plan is the closest possible solution to the current event among conventional handling methods, including but not limited to the allocation of various resources and post-event handling actions. The simulation results refer to the summary information obtained after conducting feasibility studies on the contingency plan, including the probability of feasibility, input costs, and the degree of impact.

[0045] Understandably, by analyzing user interactions in consultation scenarios, such as selecting resources, defining paths, or setting parameters, these interactions are converted into structured operational instructions. Based on event type and context, the optimal contingency plan is intelligently retrieved and loaded from the contingency plan knowledge base, containing resource scheduling logic and handling process rules. Subsequently, a visual simulation based on a rule engine and physical simulation model is initiated in a 2D / 3D integrated scenario to dynamically simulate the contingency plan execution process, such as vehicle movement, personnel evacuation, and disaster spread, and to calculate key simulation indicators in real time, such as resource arrival time and changes in the scope of impact. Finally, the simulation engine integrates spatiotemporal constraints and rule logic to output quantitative simulation results, including the feasibility probability of the solution, resource consumption costs, and expected impact, providing decision-makers with intuitive data support.

[0046] In one feasible implementation, the steps of generating operation information in response to user operation, retrieving a contingency plan matching the event information based on the operation information, and visually simulating the contingency plan in the integrated 2D / 3D visualization consultation scenario to obtain the simulation result include: In response to user operation, operation information is generated. When the operation information is to invoke a contingency plan, one or more contingency plans are matched and retrieved from the contingency plan library based on the type, level and key attributes of the real-time event information. The contingency plan text information and structured data are loaded into the two-dimensional integrated visualization consultation scenario. The structured data includes contingency resources, action routes, and key nodes. The structured data in the contingency plan is automatically associated and mapped with the spatial elements in the two-dimensional integrated visualization consultation scene. The contingency resources are bound to the corresponding models in the two-dimensional integrated visualization consultation scene. The action route is planned and visualized in three dimensions in the two-dimensional integrated visualization consultation scene. The key nodes are marked with three-dimensional icons in the two-dimensional integrated visualization consultation scene. Based on the scheduling instructions of the operation information, the handling plan in the integrated two-dimensional and three-dimensional visualization consultation scenario is visualized and simulated to obtain the simulation results.

[0047] In its implementation, when the system detects a user action (such as clicking the "Invoke Contingency Plan" button), it first parses the action information and, based on the type, level, and key attributes of the real-time event information (such as event type code and severity value), uses a weighted similarity algorithm to match contingency plans from the contingency plan library. The similarity calculation formula is:

[0048] in, Represents a time attribute vector, such as For type, As a level, Represents the contingency plan attribute vector. For attribute weights, This is an attribute similarity function.

[0049] After matching, the system loads the text information and structured data of the contingency plan into the visualization engine, and associates the disposal resources with the 3D model through a spatial binding algorithm, using the action route... The path planning algorithm generates a visual path in a 3D scene, and its evaluation function is:

[0050] in, For the actual cost, This is a heuristic function.

[0051] Key nodes are marked with 3D icons. During the simulation, the system drives the simulation model according to the user's scheduling instructions, calculates the simulation results, and finally outputs quantitative indicators such as feasibility probability, cost estimation, and impact degree, thereby completing the visualized simulation.

[0052] In one feasible implementation, the step of using the scheduling instruction based on the operation information to perform a visual simulation of the contingency plan in the integrated 2D / 3D visualization consultation scenario and obtain the simulation result includes: When the number of the two-dimensional integrated visualization consultation scenarios is greater than the preset number, visualization simulations are performed on different two-dimensional integrated visualization consultation scenarios to obtain the corresponding initial simulation results. A feasibility assessment is performed on the initial simulation results to obtain the corresponding feasibility score; The initial simulation result corresponding to the highest feasibility score in the feasibility score is output as the simulation result.

[0053] In its implementation, when the system detects that the number of generated integrated 2D / 3D visualization consultation scenarios exceeds a preset threshold (e.g., N>1), it activates a parallel simulation engine to create an independent simulation instance for each scenario. Each instance, based on its corresponding contingency plan, performs discrete event simulation within a unified time step. Key indicators are calculated using resource scheduling algorithms and a physics engine to form an initial simulation result vector containing dimensions such as time cost, resource consumption, and coverage. Then, a feasibility assessment is performed to determine a feasibility score, using the following formula:

[0054] in, The feasibility score for the i-th contingency plan is... Let j be the weight of the j-th evaluation indicator. It is the original value of the i-th plan on the j-th indicator. This is the index normalization function.

[0055] After the evaluation is completed, the system selects the highest-scoring contingency plan as the final deduction result through a ranking algorithm, and highlights the deduction process of the optimal contingency plan and compares it with key indicators through a visualization engine, providing decision-makers with data-driven basis for selecting the contingency plan.

[0056] In one feasible implementation, before the step of performing a visual simulation of the contingency plan in the two-dimensional integrated visualization consultation scenario based on the scheduling instruction of the operation information to obtain the simulation result, the method further includes: Upon receiving frontline data from the frontline execution terminal, environmental impact parameters are generated based on the frontline data. The integrated 2D / 3D visualization consultation scenario is updated based on the environmental impact parameters.

[0057] In practical implementation, when real-time frontline data is received from frontline execution terminals such as drones, individual soldier equipment, and sensors via IoT gateways or mobile communication networks, the data analysis engine extracts key environmental features and transforms them into quantified environmental impact parameters. The frontline data can include on-site images, environmental readings, and resource status, while key environmental features can include fire temperature, pollutant concentration, and road accessibility. These parameters are input into the simulation model of the simulation engine in real time, driving the dynamic updates of the integrated 2D and 3D consultation scenario—for example, correcting disaster spread paths, adjusting resource allocation routes, and updating the affected area range. This ensures that the visualized simulation process remains synchronized with the real environment, thereby guaranteeing the accuracy and effectiveness of the simulation results and forming a closed-loop optimization of "perception-simulation-decision-feedback".

[0058] Step S40: Based on the simulation results, generate scheduling decision information and send the scheduling decision information to the front-line execution terminal for urban operation event consultation and scheduling.

[0059] It should be noted that dispatch decision information refers to the set of executable, structured instructions generated by the system after visually simulating the contingency plan. It includes key elements such as specific action plans, resource allocation strategies, timeline arrangements, and spatial path planning, used to directly guide frontline execution terminals in carrying out actual response actions.

[0060] Understandably, the system first converts the simulation results into structured scheduling instructions through a rules engine; then, it sends the instructions to the front-line execution terminals in real time through message middleware or proprietary communication protocols; after receiving the instructions, the terminals convert them into actionable guidance information through the built-in instruction parsing module, and use geofencing technology to achieve automated monitoring and feedback of the action process, ultimately forming a precise linkage from virtual simulation to physical execution.

[0061] In one feasible implementation, the step of generating scheduling decision information based on the simulation results and distributing the scheduling decision information to the front-line execution terminal includes: The simulation results are analyzed to obtain the estimated handling time, resource adequacy, and risk points of the plan; Based on the estimated processing time, the resource adequacy, and the risk points of the plan, determine the resource allocation plan, action route planning, and task time nodes; Based on the resource allocation plan, the action route plan, and the task time nodes, scheduling decision information is generated; The scheduling decision information is then sent to the front-line execution terminals.

[0062] In its implementation, the system first structures the simulation results through a result parsing engine: the estimated handling time is calculated using a time series analysis algorithm, resource sufficiency is assessed based on a resource supply and demand matching model, and risk points are extracted from a risk identification rule base. Next, the decision generation engine determines the optimal solution based on a multi-objective optimization algorithm: the resource allocation plan uses a constrained linear programming model, the action route planning combines the A* algorithm and real-time traffic data, and the task time nodes are determined using the critical path method. The generated scheduling decision information is encapsulated in a standardized format, containing structured fields such as resource ID, GPS coordinates, and timestamps. Finally, the decision information is pushed to the front-line execution terminals in real time. The terminal devices verify the authenticity of the instructions through digital signatures and then automatically load and execute them, forming a complete "analysis-decision-execution" closed loop.

[0063] In one feasible implementation, the step of generating scheduling decision information based on the resource allocation plan, the action route planning, and the task time nodes includes: The resource allocation plan, the action route planning, and the task time nodes are mapped to the two-dimensional integrated visualization consultation scenario to generate a visualization scheduling plan. The visualization scheduling plan is then sent to the user display terminal so that the user can generate adjustment instructions based on the visualization scheduling plan displayed on the user display terminal. The system receives adjustment instructions generated based on the visual scheduling scheme, updates the visual scheduling scheme and sends it to the user display terminal until it receives a confirmation instruction from the user display terminal, and then generates scheduling decision information based on the updated visual scheduling scheme.

[0064] In its implementation, the system utilizes the visualization engine's API to map resource allocation plans, action route planning, and task time nodes onto a unified 2D / 3D scene, generating a dynamic visual scheduling plan, which is then pushed to the user's display terminal in real time. Users generate adjustment commands through the terminal's interactive interface. These commands are captured and sent to the backend service. The backend updates the plan data based on the spatial database and rule engine, re-renders the scene, and pushes the updated version to the terminal. This process iterates continuously until the user triggers a confirmation command. Finally, the system serializes the adjusted plan data into structured scheduling decision information for execution.

[0065] This embodiment provides a method for urban operation event consultation and scheduling based on integrated 2D and 3D data. It automatically locates events on a digital twin base map and integrates surrounding 2D and 3D dynamic and static data to quickly construct an integrated visual scene, solving the pain points of information dispersion and time-consuming integration, and greatly improving situational awareness efficiency. Next, the contingency plan is simulated and extrapolated in the visualized scene, transforming abstract text into an intuitive dynamic process, enabling decision-makers to quickly assess the feasibility of the plan and predict risks, thus improving the efficiency of plan analysis and decision-making. Finally, the optimized decision generates structured instructions, which are then issued and tracked for execution, forming a closed loop from analysis and decision-making to execution. This reduces communication layers and information distortion, thereby shortening the overall emergency response time and significantly improving consultation efficiency.

[0066] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the urban operation event consultation and scheduling method based on two-dimensional and three-dimensional integration. Any simple modifications based on this technical concept are within the protection scope of this application.
