Description

Technical Field

[0001] The present invention relates to the technical field of vegetation maintenance planning, and in particular to a path planning method, device, equipment and storage medium based on carbon sequestration efficiency. Background Art

[0002] Existing route planning systems (such as navigation technology based on the A* algorithm) use travel time or distance as a single optimization objective and fail to quantify the impact of ecological parameters such as green belt carbon sequestration efficiency and plant stress tolerance on route selection. Open-source mapping platforms (such as OpenStreetMap) provide road geometry, but lack dynamic data on the ecological performance of green belts (such as real-time carbon sequestration and pollution absorption capacity). This makes navigation algorithms unable to guide vehicles to choose routes with high ecological value.

[0003] Traditional path planning algorithms (such as Dijkstra and A*) prioritize efficiency as their sole optimization objective, failing to balance time costs and ecological gains in path selection. Furthermore, path planning systems are completely disconnected from vegetation maintenance databases: navigation decisions do not rely on plant health data (such as photosynthesis efficiency and soil contamination levels), and landscaping maintenance departments are unable to use traffic parameters such as traffic density and emission levels to predict plant stress resistance. This disconnect has trapped urban road networks in a vicious cycle of low utilization of high-ecological-value sections and overloaded high-loss sections, hindering the deep integration of smart transportation and ecological cities. Summary of the Invention

[0004] The present invention provides a path planning method, device, equipment and storage medium based on carbon sequestration efficiency to achieve multi-objective coordinated optimization of traffic efficiency and ecological value, greatly improving the overall carbon sequestration efficiency of the target area, and providing smart cities with path decisions that combine traffic efficiency and ecological sustainability.

[0025] Example 1

[0026] Figure 1 This is a flow chart of a path planning method based on carbon sequestration efficiency provided in the first embodiment of the present invention. This embodiment is applicable to situations where travel paths are planned based on the carbon sequestration capacity and path efficiency of roads. This method can be executed by a path planning device based on carbon sequestration efficiency. The path planning device based on carbon sequestration efficiency can be implemented in the form of hardware and / or software. The path planning device based on carbon sequestration efficiency can be configured in an electronic device. Figure 1 As shown, the method includes:

[0027] S101: Obtain first request information for all requested path planning in a target area.

[0028] The target area may be an area where road vegetation maintenance is to be performed, for example, a city. The first request information may be request information for a user to plan a travel route. The first request information includes at least a path starting node and a path ending node. It should be noted that the path starting node and the path ending node may respectively refer to a road in the target area, and different locations on the same road may be considered the same path starting node or path ending node.

[0029] For example, the present invention can be applied to an open source map platform, where the open source map platform receives first request information for route planning triggered by travel needs of users within a target area. The route's starting node can be determined based on the starting point information entered by the user in a starting point box of the open source map platform, or based on the user's current location information. The route's ending node can be determined based on the end point information entered by the user in an end point box of the open source map platform.

[0030] S102: For each first request information, determine a target planning path that meets preset conditions based on a first planning algorithm, according to the path starting node and the path ending node.

[0031] The first planning algorithm is an algorithm for implementing path planning for the first request information. It should be noted that the first planning algorithm is obtained by improving the path planning algorithm (such as the A* algorithm) based on the path carbon sequestration efficiency. The first planning algorithm embeds the path carbon sequestration efficiency on the basis of the traditional path planning algorithm, which can achieve multi-objective coordinated optimization of traffic efficiency (driving time) and ecological value (carbon sequestration efficiency). Although the first planning algorithm requires sacrificing a small amount of path planning efficiency, it can enhance the carbon sequestration benefit in the target area. The preset conditions include minimizing the total cost of driving time and carbon sequestration efficiency.

[0032] Specifically, for each first request information, the first planning algorithm is used to calculate the optimal path between the path starting node and the path ending node with the minimum total cost of driving time and carbon sequestration efficiency as the constraint condition, so as to obtain the target planning path that meets the preset conditions.

[0033] Exemplarily, determining the target planning path that meets preset conditions based on the path starting node and the path ending node based on the first planning algorithm includes:

[0034] Determine a first actual cost between the path originating node and the current path node; determine a second predicted cost between the current path node and the path ending node;

[0035] Based on the first actual cost and the second predicted cost, a planned path with the minimum total cost of travel time and carbon sequestration efficiency between the path starting node and the path ending node is determined, and the planned path with the minimum total cost is determined as the target planned path.

[0036] It should be noted that the current path node can refer to the latest node on the determined path in path planning. The current path node varies with the progress of path planning. For example, at the beginning of path planning, the current path node can be the path starting node; at the end of path planning, the current path node can be the path ending node.

[0037] The first actual cost may refer to the currently determined actual cost, i.e., the actual cost between the starting node and the current node of the route. The second predicted cost may refer to the cost predicted based on the current node and the end node of the route. It is worth noting that the first planning algorithm is an improvement to the path planning algorithm based on the carbon sequestration efficiency of the route. Therefore, both the first actual cost and the second predicted cost include the total cost of travel time and carbon sequestration efficiency.

[0038] Specifically, after obtaining the first actual cost and the second predicted cost, the planned path with the minimum total cost of travel time and carbon sequestration efficiency is determined as the target planned path. For example, the total cost of the first actual cost and the second predicted cost is as follows:

[0039] f(n)=h(n)+g(n);

[0040] Among them, f(n) refers to the total cost, h(n) refers to the second predicted cost, and g(n) refers to the first actual cost.

[0041] Exemplarily, determining the second predicted cost between the current path node and the path end node includes: determining a time heuristic function based on the current path node and the path end node; determining an ecological heuristic function based on the current node carbon sequestration efficiency corresponding to the current path node, and the second maximum carbon sequestration efficiency and the shortest node distance between the current path node and the path end node; determining the second predicted cost based on the time heuristic function and the ecological heuristic function, as well as the time coefficient and the ecological coefficient.

[0042] Exemplarily, a time heuristic function is determined according to the current path node and the path end node as follows:

[0043]

[0044] Among them, h geo (n) refers to the time heuristic function, x n Refers to the horizontal coordinate of the current path node, x goal Refers to the horizontal coordinate of the end node of the path, y n Refers to the current path node ordinate, y goal Refers to the vertical coordinate of the end node of the path, v avg It refers to the average travel speed between the current path node and the path end node.

[0045] Exemplarily, the ecological heuristic function is determined as follows:

[0046]

[0047] Among them, h carbon (n) refers to the ecological heuristic function, C current Refers to the carbon sequestration efficiency of the current node, ∑p∈Path opt C eff (p) refers to the second maximum carbon sequestration efficiency, d(n,goal) refers to the shortest distance between the nodes, v avg It refers to the average travel speed between the current path node and the path end node.

[0048] Exemplarily, determining the second prediction cost according to the time heuristic function and the ecological heuristic function, as well as the time coefficient and the ecological coefficient, includes:

[0049] h(n)=α·h geo (n)+β·h carbon (n);

[0050] Among them, h(n) refers to the second prediction cost, h geo (n) refers to the time heuristic function, h carbon (n) refers to the ecological heuristic function, α refers to the time coefficient, and β refers to the ecological coefficient.

[0051] For example,

[0052]

[0053] Among them, this formula is a real-time weight adjustment formula based on traffic pressure, α refers to the time coefficient, R represents the real-time traffic pressure comprehensive index, R0 is the baseline pressure threshold (default 0.7) depends on the traffic efficiency of urban roads, and k is the adjustment sensitivity coefficient (default 3.0).

[0054]

[0055] Where η represents the congestion index weight (default 0.2), I t Is the congestion index, from the third-party navigation platform data (0-10 points), I max Indicates the maximum value of the congestion index (default is 10), Q is the traffic volume during the statistical period, Q max is the road design capacity.

[0056]

[0057] β only needs to satisfy the conditions of this formula. It refers to the maximum theoretical road carbon sequestration efficiency between the current path node and the path end node, d min It refers to the shortest straight-line distance between the current path node and the path end node.

[0058] Exemplarily, after determining the target planning path that meets the preset conditions, the method further includes:

[0059] According to all the target planned paths in the target area, road planning information of each regional road in the target area is determined, and vegetation maintenance is performed on each regional road in the target area according to the road planning information.

[0060] The road planning information may be planning information of each regional road in the target area being planned as a driving road.

[0061] Specifically, by analyzing all planned routes within a target area, we can obtain road planning information for each regional road within the target area. This road planning information is then analyzed and processed to determine the number and proportion of planned routes for each regional road. Based on this road planning information, vegetation maintenance is then performed on each regional road within the target area. For example, if a regional road is designated as an ecological route for 30 consecutive days, an upgrade in maintenance level (drip irrigation frequency +50%, pruning cycle -30%) is automatically triggered.

[0062] Furthermore, the present invention can modify travel routes based on other conditions. For example, when the carbon sequestration efficiency of a road in a certain area drops by 15% or more, a detour suggestion can be generated and a maintenance work order can be pushed.

[0063] On the basis of the above embodiments, vegetation maintenance is performed on each regional road in the target area according to the road planning information, including: for each regional road, determining the road planning proportion of the regional road planned as a driving road under the same type of first request information according to the road planning information; when the road planning proportion is greater than a first preset proportion, replanting preset carbon sequestration vegetation in the regional road based on preset intervals; when the road planning proportion is less than a second preset proportion, reducing the ecological coefficient of the regional road; otherwise, no vegetation maintenance is performed on the regional road.

[0064] The first preset ratio and the second preset ratio can be set according to actual conditions, and the second preset ratio is smaller than the first preset ratio. The road planning ratio may refer to the ratio of roads planned as travelable roads under the same type of first request information. The same type of first request information may mean that, in multiple first request information, the originating node of each first request information path is located on the same road, and the ending node of the path is also located on the same road.

[0065] Specifically, the road planning information corresponding to similar first request information is compared to determine the proportion of roads in each region that are planned as travelable roads based on the same first request information. If the planned road ratio is greater than a first preset ratio, pre-set carbon-sequestering vegetation is replanted within the regional roads at preset intervals, such as replanting similar high-carbon-sequestering plants every 50 meters. If the planned road ratio is less than a second preset ratio, the ecological coefficient of the regional roads is reduced. Otherwise, vegetation maintenance is not performed on the regional roads.

[0066] The technical solution of the embodiment of the present invention is to obtain the first request information of all requested path planning in the target area, wherein the first request information includes at least the path starting node and the path ending node. For each of the first request information, based on the first planning algorithm, according to the path starting node and the path ending node, a target planning path that meets the preset conditions is determined, wherein the first planning algorithm is obtained by improving the path planning algorithm based on the path carbon sequestration efficiency, and the preset conditions include minimizing the total cost of driving time and carbon sequestration efficiency. The present invention realizes the dynamic balance optimization of traffic efficiency and ecological benefits by quantifying the path carbon sequestration efficiency and embedding it into the improved first planning algorithm. While minimizing the travel time, the planned path gives priority to sections with high carbon sequestration efficiency, thereby driving the matching of traffic distribution and ecological resources, forming a positive cycle of "traffic diversion-carbon sequestration gain", and providing smart cities with path decisions that have both traffic efficiency and ecological sustainability.

[0067] Example 2

[0068] Figure 2 This is a flow chart of a route planning method based on carbon sequestration efficiency provided by the second embodiment of the present invention. Based on the above embodiments, this embodiment further refines the process of determining the carbon sequestration efficiency of each road. Figure 2 As shown, the method includes:

[0069] S201. Obtain vegetation species information, traffic flow information, noise information, and vegetation growth information corresponding to a target path for which carbon sequestration efficiency is to be determined.

[0070] Specifically, municipal greening databases can be integrated to obtain information on vegetation species, planting density, and growth cycles; real-time traffic flow monitoring data, including volume, vehicle type, and emission levels, can be obtained from traffic management platforms; noise information from noise sensors can be obtained from environmental monitoring stations; and vegetation microenvironmental parameters collected by IoT devices deployed in green belts can be collected. Furthermore, spatiotemporal matching algorithms can be used to accurately correlate and update multi-dimensional data in real time.

[0071] S202: Determine theoretical vegetation carbon sequestration data for the target path based on the vegetation species information.

[0072] For example, the process of determining theoretical vegetation carbon sequestration data is as follows:

[0073] C base =LAI×P max ×φ light ×t active ;

[0074] Where LAI is the leaf area index, which depends on the plant species, P max is the maximum photosynthetic rate, which also depends on the species, lightis the light energy utilization efficiency, t active It is the effective photosynthetic duration of the year, which depends on the region.

[0075] S203: Determine a traffic exhaust suppression factor for the target path based on the traffic information.

[0076] Exemplarily, the process of determining the vehicle exhaust suppression factor is as follows:

[0077]

[0078] Among them, γ is the exhaust gas sensitivity coefficient, Q is the traffic volume in the statistical period, and Q max is the road design capacity.

[0079] S204: Determine an environmental noise interference factor of the target path based on the noise information.

[0080] Exemplarily, the process of determining the environmental noise interference factor is as follows:

[0081] λ noise =1-0.015×max(0,N-65);

[0082] Where N is the average noise decibel during the statistical period.

[0083] S205: Determine a vegetation growth cycle factor of the target path based on the vegetation growth information.

[0084] For example, the process of determining the vegetation growth cycle factor is as follows:

[0085] λ growth =1-e -k·t ;

[0086] where k is the growth rate constant, which depends on the species, and t is the number of years the vegetation has been planted.

[0087] S206. Determine the carbon sequestration efficiency corresponding to the target path based on the vegetation theoretical carbon sequestration data, the vehicle exhaust suppression factor, the environmental noise interference factor, and the vegetation growth cycle factor.

[0088] Exemplarily, the carbon sequestration efficiency determination process is as follows:

[0089] C eff =C base ×λ traffic ×λ noise ×λ growth ;

[0090] Among them, C base is the theoretical carbon sequestration data of vegetation, λ traffic ,λ noise,λ growth They are all dynamic performance correction factors, representing the traffic exhaust suppression factor, environmental noise interference factor and vegetation growth cycle factor respectively.

[0091] S207: Obtain first request information for all requested path planning in the target area.

[0092] S208: For each first request information, based on a first planning algorithm, determine a target planning path that meets preset conditions according to the path starting node and the path ending node.

[0093] The technical solution of the embodiment of the present invention determines the carbon sequestration efficiency corresponding to the target path through theoretical vegetation carbon sequestration data, the vehicle exhaust suppression factor, the environmental noise interference factor and the vegetation growth cycle factor, breaking through the limitations of traditional static evaluation. It not only quantifies the real-time loss of plant carbon sequestration capacity caused by traffic pollution and noise, but also predicts the carbon sequestration potential of vegetation in combination with the growth cycle, providing high-resolution ecological parameters for path planning and maintenance decisions.

[0098] The technical solution of the embodiment of the present invention is to obtain the first request information of all requested path planning in the target area, wherein the first request information includes at least the path starting node and the path ending node.
