DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] In an exemplary embodiment, Figure 1 As shown, a method for generating a measurement plan for a river control project is provided, comprising: S101, generating a river prevention and control path and a path measurement task corresponding to the river prevention and control path according to a river area in a target scene.

[0024] First, analyze the river area in the target scenario, including: analyzing the topographic and geomorphic features of the river area, including the direction, width, depth, curvature of the river, and the topographic undulations and geomorphic types on both sides of the river. Understand the hydrological conditions of the river, including water flow velocity, water level changes, water quality conditions, etc., as well as the river's flood history and flood control capabilities. Assess the ecological and environmental conditions of the river area, including vegetation coverage, biodiversity, water pollution levels, etc., as well as the impact of the river on the surrounding ecological environment. Clarify the goals of river prevention and control, such as improving flood control capabilities, improving water quality, protecting the ecological environment, etc., as well as the specific requirements and restrictions of prevention and control projects.

[0025] Optionally, when generating a river prevention and control path, the following method can be used: Based on the analysis results of the river area, determine the key areas and key links of prevention and control, such as river sections prone to flooding, areas with serious water pollution, etc. Combined with the prevention and control goals and key areas, plan a reasonable prevention and control path. This usually includes determining the starting point, end point and key nodes of the prevention and control project, as well as the direction and layout of the path. When planning a prevention and control path, it is necessary to consider the feasibility of the project, including construction conditions, material sources, technical difficulty and other factors to ensure the feasibility of the path and the implementation effect.

[0026] Furthermore, after the river control path is generated, the specific requirements of the path measurement task are clarified according to the planning of the control path, including the measurement range, accuracy, time point, etc. According to the measurement requirements, appropriate measurement methods and technologies are selected, such as remote sensing measurement, drone aerial survey, ground measurement, etc. Combined with the measurement methods and requirements, a detailed measurement plan is formulated, including the division of labor of measurement personnel, the configuration of measurement equipment, and the arrangement of measurement time.

[0027] S102: Determine the path measurement complexity of the path measurement task according to the environmental information of the target scene in the historical period.

[0028] The environmental information includes at least weather information, geographic information and traffic information.

[0029] For example, weather information includes weather data of the target scene in the historical period, such as rainfall, temperature, humidity, wind speed, wind direction, etc. Geographic information includes river width, depth, flow rate, flow direction, river terrain, obstacle location, etc. Traffic information includes river traffic flow, bridge and ferry location, regulatory restrictions, and other traffic-related information.

[0030] Specifically, the path measurement complexity of the path measurement task is determined according to the environmental information of the target scene in the historical period, including: inputting the environmental information of the target scene in the historical period into the environmental analysis model, and obtaining the path measurement complexity of the path measurement task output by the environmental analysis model.

[0031] Among them, the environmental analysis model is constructed using an improved multi-factor comprehensive evaluation algorithm.

[0032] Specifically, the model training process of the environmental analysis model is: First, weather information, geographic information, and traffic information are used as key factors to evaluate the complexity of path measurement. Since the data units and dimensions of different factors may be different, the collected environmental information needs to be standardized to ensure that each factor has equal weight in the evaluation.

[0033] Secondly, assign corresponding weights to each factor according to its importance. This can be determined by expert scoring, analytic hierarchy process (AHP) or entropy weight method. The weight allocation should take into account the possible mutual influence and constraint relationship between different factors.

[0034] Finally, the improved multi-factor comprehensive evaluation algorithm is used to multiply the standardized data by the corresponding weight to obtain the comprehensive evaluation value of each factor. Then, the comprehensive evaluation values ​​of all factors are added together to obtain the overall complexity of the path measurement task.

[0035] S103, generating a measurement plan for the river control path in a future period according to the path measurement complexity and the path measurement task corresponding to the river control path.

[0036] The measurement plan includes at least the measurement location in the river control path, the measurement period corresponding to the measurement location, the measurement equipment required for the measurement location, and the measurement strategy adopted by the measurement equipment.

[0037] It can be understood that key nodes refer to key nodes that need to be measured based on the planning of river control paths and analysis of path measurement complexity, such as river bends, areas with large changes in depth, possible obstacle locations, etc. On the premise of ensuring that the entire control path is covered, the measurement locations are distributed as evenly as possible to obtain a more comprehensive understanding of the river situation.

[0038] Furthermore, the measurement location can be dynamically adjusted based on historical data and real-time monitoring results to cope with changes in river conditions.

[0039] Then, according to the complexity of path measurement and prevention and control needs, set a regular measurement cycle, such as weekly, monthly or quarterly measurement.

[0040] Furthermore, the measuring equipment is selected according to the measuring location, measuring cycle and measuring accuracy requirements; then, the type and quantity of equipment required for each measuring location are determined to ensure the smooth progress of the measuring work.

[0041] In the above-mentioned method for generating a measurement plan for a river control project, by generating a specific river control path, river management and control work can be carried out in a more targeted manner, thereby improving the control efficiency. According to the actual situation in the target scenario, the customized path measurement task can ensure the accuracy and effectiveness of the measurement. Considering the environmental information in the historical period (such as weather, geography, traffic, etc.), the complexity of the path measurement task can be more accurately evaluated, and the measurement plan can be dynamically adjusted in the future period to cope with possible changes and challenges. By accurately determining the measurement location, measurement cycle, required measurement equipment, and measurement strategy, unnecessary measurement and equipment use can be avoided, thereby reducing measurement costs. The measurement plan generated by comprehensively considering multiple factors can ensure that the most appropriate measurement equipment is used for measurement at the best time and place, thereby improving the accuracy and reliability of the measurement data.

[0042] In an exemplary embodiment, Figure 2 As shown in the figure, according to the river area in the target scene, a river control path is generated, including: S201, determining a key position for river control in the target scene according to target river characteristics corresponding to a river area in the target scene.

[0043] Among them, river characteristics include at least river direction, width, depth and water flow speed.

[0044] Optionally, the direction and path of the river can be identified through maps or remote sensing images. The impact of river direction on water flow dynamics, sediment transport and pollutant dispersion can be analyzed.

[0045] Furthermore, the width of the river can be measured at different locations to identify areas with large width changes, which may be the focus of water velocity changes, silt accumulation or scour.

[0046] Furthermore, river depth data can be obtained using bathymetric equipment or remote sensing technology to analyze depth changes, especially the distribution of deep and shallow water areas, which have an important impact on the behavior of water flow, sediment and pollutants.

[0047] Furthermore, water velocity data is obtained through field measurements or numerical simulations. Changes in water velocity are analyzed to identify high-speed and low-speed flow areas, which may involve the concentration and consumption of water flow energy.

[0048] Among them, key locations for river control may include: 1) Bends: The bends of rivers are areas with complex flow dynamics, where sediment deposition and scour are prone to occur. According to the changes in the direction and width of the river, bends should be identified and marked as key locations for prevention and control.

[0049] 2) Wide and shallow sections and deep and narrow sections: Wide and shallow sections may be prone to sedimentation and pollutant retention, while deep and narrow sections may form high-speed flow areas, aggravating riverbed erosion. These key sections are determined by analyzing river width and depth data.

[0050] 3) Areas of water velocity change: Changes in water velocity will affect the movement of sediment and pollutants. Based on water velocity data, identify areas where velocity changes significantly, especially the junction of high-speed and low-speed flow areas.

[0051] 4) Other special areas: such as river confluences, estuaries, unstable sections of embankments, etc. These areas may also become key locations for prevention and control.

[0052] Overlay the key locations identified above to find overlapping or adjacent areas, which may be complex areas where multiple problems coexist. Conduct risk assessment for each key location, considering its impact on river ecosystems, flood control safety, water quality protection, etc. Based on the risk assessment results, determine the prevention and control strategies for each key location, such as strengthening embankments, dredging rivers, and building ecological revetments.

[0053] S202, with the goal of minimizing construction costs and the constraints of satisfying construction feasibility conditions, a path optimization algorithm is used to generate a river control path covering key locations for river control.

[0054] Among them, construction feasibility conditions include at least geological stability conditions, hydrological conditions, traffic conditions, equipment and technical conditions, and safety conditions.

[0055] Specifically, the determination of geological stability conditions includes geological exploration reports to identify unstable geological areas. The determination of hydrological conditions includes collecting hydrological data to understand changes in water levels, flow rates, etc. The determination of traffic conditions includes investigating surrounding traffic conditions, including roads, bridges, etc. The determination of equipment and technical conditions includes evaluating existing equipment and technical capabilities and determining construction restrictions. The determination of safety conditions includes analyzing safety risks during construction and formulating safety specifications.

[0056] Optionally, key location data, construction feasibility condition data and cost function are input into the path optimization model. The path optimization algorithm is executed to generate a prevention and control path covering all key locations. Based on the algorithm output, the path with the lowest cost is selected as the optimal solution.

[0057] In an exemplary embodiment, Figure 3 As shown in the figure, with the goal of minimizing construction costs and the constraints of satisfying construction feasibility conditions, a path optimization algorithm is used to generate a river control path covering the key control points, including: S301, with the goal of minimizing construction costs and the constraints of satisfying construction feasibility conditions, a path optimization algorithm is used to generate an initial river path covering key locations for river control.

[0058] Optionally, collect and organize information on key river control locations, including location coordinates, control requirements, etc. Obtain detailed maps or remote sensing images of the construction area for path planning. Collect relevant data on construction feasibility conditions, such as geological survey reports, hydrological data, traffic conditions, etc. Select an appropriate path optimization algorithm based on the scale and complexity of the problem. Commonly used algorithms include Dijkstra algorithm, A* algorithm, genetic algorithm, etc. These algorithms can generate optimal or near-optimal paths based on different optimization objectives and constraints.

[0059] Using the collected data and the selected algorithm, a path optimization model is constructed. In the model, the construction cost is used as the objective function and the construction feasibility conditions are used as constraints. The path optimization algorithm is executed to generate an initial river path covering all key locations for river control. The algorithm searches and finds the path with the lowest cost based on the objective function and constraints.

[0060] S302, in the river record library, query the historical river path corresponding to the historical river characteristics matching the target river characteristics.

[0061] Specifically, historical river paths that match the characteristics of the target river are searched in the river record library so that past experience can be used to guide current path planning.

[0062] S303, based on the path construction records of the historical river paths, potential construction failures in the initial river path are analyzed to optimize the initial river path to obtain a river control path covering the key control point locations.

[0063] Optionally, based on the construction records of historical river paths, possible construction failures in the initial river path are analyzed and optimized to obtain a more reliable and economical river control path.

[0064] Obtain detailed construction records for the selected historical river path. These records should include problems, failures, solutions, and final construction results during the construction process. Conduct in-depth analysis of the failures in the construction records to find out the causes of the failures, the types of failures, and the impact of the failures on construction costs and time. Based on the analysis results of historical failures, identify potential construction failures that may exist in the initial river path. These failures may include geological instability, water scouring, equipment failure, etc.

[0065] Furthermore, the initial river path is optimized for the identified potential failures. Optimization measures may include adjusting the path direction, adding support structures, switching to more reliable construction equipment, etc. Through simulation or actual construction, it is verified whether the optimized path can effectively avoid or reduce the occurrence of construction failures and ensure that construction costs and time are reasonably controlled.

[0066] In this embodiment, by implementing steps S302 and S303, historical data and experience are fully utilized to guide the generation and optimization of the river control path, so that the final river control path will be more in line with actual construction needs.

[0067] In an exemplary embodiment, Figure 4 As shown in the figure, with the goal of minimizing construction costs and the constraints of satisfying construction feasibility conditions, a path optimization algorithm is used to generate an initial river path covering key locations for river control, including: S401, obtaining terrain description information of key prevention and control points.

[0068] The terrain description information includes at least topographic maps, hydrological data, geological exploration data, environmental protection requirements and construction specifications.

[0069] Specifically, collect topographic maps of key prevention and control points to understand information such as terrain undulations and elevations. Collect hydrological data, including water level changes, flow velocity, and flow, to assess the impact of hydrodynamic conditions on construction. Obtain geological exploration data to understand geological structure, soil stability, etc., to ensure geological safety during construction. Check environmental protection requirements to ensure that construction activities meet ecological protection and pollution control standards. Understand construction specifications, including construction methods, material selection, safety standards, etc., to guide the standardization of the construction process.

[0070] S402, using geographic information system (GIS) tools, spatially analyzing the terrain description information to obtain a digital map containing key locations for river control.

[0071] Specifically, GIS tools are used to import topographic maps, hydrological data, geological exploration data, etc. Spatial analysis, such as overlay analysis, terrain analysis, hydrological analysis, etc., is performed to extract key terrain features. A digital map containing key river control locations and their surroundings is generated to provide a basis for subsequent path optimization.

[0072] S403, in the digital map, key river control locations are used as nodes, and construction costs are used as edges between nodes to construct a graph model.

[0073] For example, in a digital map, key river control locations are nodes, representing points that need to be addressed or paid attention to. Construction costs are used as edges between nodes to represent the cost of construction from one key location to another. Construction costs can take into account factors such as material costs, labor costs, and equipment costs. A graph model is constructed, including nodes, edges, and related weights (construction costs), to provide input for subsequent path optimization algorithms.

[0074] S404, with the goal of minimizing the construction cost and the constraints of satisfying the construction feasibility conditions, an initial river path covering the key prevention and control points is generated in the digital map according to the path optimization algorithm corresponding to the graph model.

[0075] Optionally, select a suitable path optimization algorithm, such as Dijkstra algorithm, A* algorithm, genetic algorithm, etc. These algorithms can find the minimum cost path based on the nodes and edges in the graph model. With the goal of minimizing the construction cost, the construction feasibility conditions (such as geological stability, hydrological conditions, traffic conditions, etc.) are input into the path optimization algorithm as constraints. Run the algorithm in the digital map to generate an initial river path covering all key prevention and control points. The path should meet the construction feasibility conditions and minimize the construction cost. Output the initial river path results, including the path direction, length, key locations along the way, etc., to provide guidance for subsequent detailed design and construction.

[0076] In this embodiment, through the implementation of steps S401 to S404, terrain description information is systematically collected and analyzed, a graph model is constructed, and a path optimization algorithm is applied to generate an initial river path. This process ensures that the generation of the path not only takes into account the minimization of construction costs, but also meets the requirements of construction feasibility conditions.

[0077] In an exemplary embodiment, Figure 5 As shown, according to the environmental information of the target scene in the historical period, the path measurement complexity of the path measurement task is determined, including: S501, dividing the river control path to obtain a plurality of adjacent sub-segments.

[0078] Specifically, the river control path is divided into multiple adjacent sub-sections according to its characteristics and measurement requirements, ensuring that each sub-section has a clear starting point and end point, and that the sub-sections are seamlessly connected.

[0079] S502: Determine the section measurement task of each sub-section according to the path measurement task corresponding to the river control path.

[0080] Specifically, according to the path measurement tasks corresponding to the river control path, determine the specific content that needs to be measured in each sub-section, such as water level, flow rate, water quality, etc. Determine the measurement frequency and measurement time of each sub-section to ensure the continuity and accuracy of the data.

[0081] S503: Determine the measurement complexity of each sub-road section according to the environmental information of the target scene in the historical period.

[0082] Specifically, collect environmental information of the target scene in the historical period, including data on climate, hydrology, geology, etc. According to the environmental information and the measurement tasks of the sub-section, evaluate the complexity of each sub-section measurement. The complexity may be affected by many factors, such as terrain complexity, water flow speed, accessibility of measurement equipment, etc.

[0083] S504: Determine the path measurement complexity of the path measurement task according to the road section measurement complexity corresponding to each sub-road section.

[0084] Specifically, the complexity of the route measurement of each sub-segment is summarized and analyzed. According to the complexity of the sub-segments and their proportion in the overall route, the overall complexity of the route measurement task is determined.

[0085] Correspondingly, based on the path measurement complexity and the path measurement tasks corresponding to the river control path, a measurement plan for the river control path in the future time period is generated, including: for each sub-section, based on the section measurement complexity corresponding to the sub-section and the section measurement tasks corresponding to the sub-section, a section measurement plan for the sub-section in the future time period is generated; based on the section measurement plans of each sub-section in the future time period, a measurement plan for the river control path in the future time period is generated.

[0086] Optionally, for each sub-section, a specific section measurement plan is formulated according to the measurement complexity and measurement tasks of the section. The plan should include measurement methods, measurement equipment, measurement personnel, safety measures, etc.

[0087] Integrate and coordinate the road measurement plans of each sub-section to ensure their connection and coordination.

[0088] Generate an overall measurement plan for the river control path in the future period. The plan should clearly define the measurement objectives, measurement cycle, measurement resource requirements, risk management, etc. to ensure the smooth progress of the measurement work.

[0089] In an exemplary embodiment, the road section measurement tasks corresponding to the sub-road sections include field measurement tasks, office measurement tasks, and control measurement tasks.

[0092] 3) Control surveying tasks refer to the surveying work carried out within a certain area to establish a control network for geodetic surveying, photogrammetry, topographic surveying and engineering surveying. It is an important part of surveying and mapping work and provides a basis for the smooth progress of other professional surveying. Control surveying tasks mainly include the following aspects: Establishing a control network: obtaining the coordinates and elevations of control points through precise measurement to form a point coordinate system that forms the skeleton of surveying and mapping results. Management and maintenance of results data: collecting, organizing, preserving and using control survey results data including drawings, tables, calculation results, etc.

[0093] like Figure 6 As shown, according to the segment measurement complexity corresponding to the sub-segment and the segment measurement task corresponding to the sub-segment, a segment measurement plan for the sub-segment in the future period is generated, such as Figure 6 As shown, including: S601, determining the position of the main control point according to the measurement complexity of the sub-section and the measurement task of the sub-section, and using the position of the main control point as the measurement position in the river control path.

[0094] Specifically, according to the measurement complexity and measurement tasks of the corresponding sub-sections, analyze and determine which positions are key control points (i.e., main control points). These main control points should be able to fully reflect the measurement characteristics of the sub-sections and facilitate measurement operations. The determined main control point locations are used as measurement locations in the river control path to provide a benchmark for subsequent measurement work.

[0095] S602, determining the measurement period corresponding to the measurement position and the measurement equipment required for the measurement position according to the measurement complexity of the road section corresponding to the sub-road section, and obtaining the field measurement plan required for executing the field measurement task of the sub-road section.

[0096] For example, the measurement cycle of the measurement location is determined according to the measurement complexity of the road section corresponding to the sub-section. The measurement cycle should take into account factors such as the need to update the measurement data and the availability of measurement resources. Determine the measurement equipment required for the measurement location, including measuring instruments, sensors, data loggers, etc. The equipment selection should be based on the requirements of the measurement task, the conditions of the measurement environment, and the performance and reliability of the equipment. Based on the information of the measurement location, measurement cycle and measurement equipment, formulate the field measurement plan required for the sub-section to perform the measurement field work task. The plan should clearly specify the measurement personnel, measurement time, measurement methods and safety measures.

Combined with the measurement of the internal work tasks and the control measurement tasks, the methods of internal data processing and analysis, the implementation methods of the control measurement, etc. are determined. Taking into account the needs of field and internal work, as well as the requirements of the control measurement, a section measurement plan for the sub-section in the future period is generated. The plan should be comprehensive and detailed, and can guide the smooth progress of the measurement work.

[0100] First, based on the surveying internal work tasks, clarify the goals and requirements of the internal work. Generate verification methods for the field surveying plan, including data inspection, outlier processing, data adjustment, etc. These methods should be able to ensure the accuracy and consistency of the field surveying data. According to the verification methods, formulate the internal surveying plan required for the sub-section to perform the surveying internal work tasks. The plan should clarify the process, methods, tools and time nodes of the internal work to ensure the smooth progress of the internal work.

[0101] Then, integrate the field measurement plan and the office measurement plan to ensure the connection and coordination between the two. This includes determining the handover point between field and office work, data transmission methods, work schedule, etc. Combined with the control measurement task, clarify the implementation method, time and personnel arrangement of the control measurement. Control measurement is an important link to ensure the accuracy and reliability of the entire measurement work, and should be closely coordinated with other measurement tasks.

[0102] Furthermore, based on the field measurement plan, the indoor measurement plan and the control measurement task, a section measurement plan for the sub-section in the future time period is generated, including: based on the field measurement plan and the indoor measurement plan, generating a plane control measurement and control system and an elevation control measurement and control system corresponding to the control measurement task; based on the field measurement plan, the indoor measurement plan, the plane control measurement and control system and the elevation control measurement and control system, generating a section measurement plan for the sub-section in the future time period.
