Description

Technical Field

[0001] The present application relates to the technical field of rural fire management, and in particular, to a rural grid-based fire management method, system, and storage medium based on GIS. Background Technique

[0002] In the management and construction of smart villages, rural fire management is of utmost importance. The countryside not only includes villages and towns but also fields and forest farms. During the fire management process, fire-fighting equipment needs to be arranged in various important areas within the countryside. At the same time, a patrol team for inspecting the fire-fighting equipment needs to be configured, and intelligent management of the patrol team is required. Through an intelligent system and based on the positions of all fire-fighting equipment, the shortest patrol route for the patrol team is planned. After receiving the shortest patrol route through the mobile phone, the patrol team conducts patrols according to the shortest patrol route.

[0003] Regarding the above-related technologies, the inventors believe that there are the following defects: During the patrol process according to the shortest patrol route generated intelligently, more attention is often paid to the inspection of fire-fighting equipment. However, there may be some areas in the countryside that are far from the fire-fighting equipment and have a relatively high risk of fire. It is difficult for the patrol team to detect these potential hazards during the patrol process, resulting in low patrol efficiency. Summary of the Invention

[0004] In order to improve the defect that the patrol route generated intelligently is difficult to target areas with a relatively high risk of fire, the present application provides a rural grid-based fire management method, system, and storage medium based on GIS.

[0005] In a first aspect, the present application provides a rural grid-based fire management method based on GIS, including the following steps:

[0006] Dividing the target rural area into multiple grids according to the GIS map of the target rural area, and respectively setting fire patrol points for each grid;

[0007] Generating a first initial patrol path for a first patrol team for each grid based on the GIS map;

[0008] Generating a second initial patrol path for a second patrol team by combining the fire patrol points of all grids and the GIS map;

[0009] Respectively obtaining the equipment usage time and historical fire data of all fire-fighting equipment within each grid;

[0010] Adjusting the first initial patrol path based on the equipment usage time to obtain a first patrol path;

[0011] Adjusting the second initial patrol path based on the historical fire data to obtain a second patrol path;

[0012] Send the first patrol path to the first mobile terminal held by the first patrol team, and send the second patrol path to the second mobile terminal held by the second patrol team; the first patrol team will conduct fire patrols within the corresponding grids according to the first patrol path, and the second patrol team will conduct fire patrols within the target village according to the second patrol path.

[0013] By adopting the above technical solution, the target village is divided into grids, which is conducive to the zonal fire management of the target village. The first initial patrol path of the first patrol team is generated according to the GIS map. Since the first patrol team patrols within each grid, the more the equipment usage time of the fire equipment within the grid, the higher the possibility of a fire near the fire equipment. Therefore, the first initial patrol path is adjusted according to the equipment usage time, and finally the first patrol path is obtained and sent to the first mobile terminal held by the first patrol team so that the first patrol team can patrol according to the first patrol path.

[0014] The second patrol team patrols the entire target village. Therefore, the second initial patrol path is first generated according to the fire patrol points set in each grid and the GIS map. Since the second patrol team patrols across grids, the grids with greater fire hazards in each grid can be analyzed based on the historical fire data of the target village, so as to adjust the second initial patrol path to obtain the second patrol path, and then the obtained second patrol path is sent to the second mobile terminal held by the second patrol team so that the second patrol team can patrol according to the second patrol path. Finally, the first patrol team and the second patrol team can not only inspect the fire equipment during the patrol of the target village according to the generated patrol paths, but also conduct key inspections on the areas with greater fire hazards.

[0015] Optionally, the step of generating the first initial patrol path of the first patrol team for each grid based on the GIS map includes the following steps:

[0016] Statistically count the number of fire equipment in each grid through the GIS map;

[0017] Based on the number of equipment and sorting all grids in descending order, a generation sequence is obtained;

[0018] Based on the positions of the fire equipment in each grid and according to the generation sequence, generate the first initial patrol path of the first patrol team in each grid.

[0019] By adopting the above technical solution, since the generation process of the first initial patrol path first requires querying the positions of each fire-fighting device one by one, then constructing the fire-fighting devices in the same grid into a set, and generating the first initial patrol path according to the positions of the fire-fighting devices in the set, the first initial patrol path of the grid with more fire-fighting devices is generated first, reducing the time spent on querying the positions of fire-fighting devices one by one in the subsequent generation process of the patrol path, thereby reducing the overall time for generating the first initial patrol paths of all grids.

[0020] Optionally, generating the second initial patrol path of the second patrol team by combining the fire patrol points of all grids and the GIS map includes the following steps:

[0021] Obtain the road information of the target rural area through the GIS map;

[0022] Taking each fire patrol point as the starting and ending points respectively and combining the road information to generate multiple shortest patrol paths, the shortest patrol paths are closed-loop paths and pass through all fire patrol points;

[0023] Calculate the patrol time required for the second patrol team to patrol one circle in each shortest patrol path respectively according to the preset patrol speed;

[0024] Select the shortest patrol path corresponding to the shortest patrol time as the second initial patrol path of the second patrol team.

[0025] By adopting the above technical solution, taking any one of the multiple fire patrol points as the starting and ending points first, and generating all feasible shortest patrol paths in combination with the road information. Since the rural roads may be relatively complex, all the generated shortest patrol paths may be different. Therefore, it is necessary to calculate the patrol time required for each shortest patrol path to patrol one circle respectively according to the preset same patrol speed, and then take the shortest patrol path with the shortest patrol time as the second initial patrol path.

[0026] Optionally, adjusting the first initial patrol path based on the device usage time to obtain the first patrol path includes the following steps:

[0027] Based on a preset usage time threshold, judge the device usage time of the passing fire-fighting devices in the first initial patrol path, and judge whether the device usage time of the passing fire-fighting devices is greater than the usage time threshold;

[0028] If the device usage time of the passing fire-fighting device is greater than the usage time threshold, mark the corresponding passing fire-fighting device as an important fire-fighting device;

[0029] If the device usage time of the fire-fighting equipment on the corresponding route is not greater than the usage time threshold, mark the corresponding fire-fighting equipment on the route as secondary fire-fighting equipment;

[0030] Count the number of important fire-fighting equipment passed by the first initial patrol route;

[0031] Determine whether the number of important fire-fighting equipment exceeds a preset quantity threshold;

[0032] If the number of important fire-fighting equipment exceeds the quantity threshold, extend the first initial patrol route based on the locations of all important fire-fighting equipment to obtain a first patrol route, where for any important fire-fighting equipment in the first patrol route, it passes by at least twice;

[0033] If the number of important fire-fighting equipment does not exceed the quantity threshold, do not adjust the first initial patrol route, and use the first initial patrol route as the first patrol route.

[0034] By adopting the above technical solution, the fire-fighting equipment within the same grid is classified according to the device usage time of the fire-fighting equipment. The fire-fighting equipment with a device usage time greater than the time threshold is marked as important fire-fighting equipment, while the fire-fighting equipment with a device usage time not greater than the time threshold is marked as secondary fire-fighting equipment. After classifying the fire-fighting equipment, count the number of important fire-fighting equipment. If the number of important fire-fighting equipment is small and lower than the preset quantity threshold, it indicates that the utilization rate of the fire-fighting equipment in this grid is not high, and there is no need to conduct key inspections on all important fire-fighting equipment; if the number of important fire-fighting equipment is large and higher than the preset quantity threshold, it indicates that the utilization rate of the fire-fighting equipment in this grid is relatively high. Therefore, it is necessary to extend and adjust the first initial patrol route according to the locations of the important fire-fighting equipment in this grid to obtain a first patrol route, so that the first patrol team can inspect all important fire-fighting equipment at least twice when patrolling according to the first patrol route.

[0035] Optionally, the step of adjusting the second initial patrol route based on the historical fire data to obtain a second patrol route includes the following steps:

[0036] Perform data analysis on the historical fire data, and assign fire warning levels to each grid according to the data analysis results. The fire warning levels include a first warning level, a second warning level, and a third warning level. The first warning level is greater than the second warning level, and the second warning level is greater than the third warning level;

[0037] Respectively determine the fire warning levels of each grid;

[0038] If the grid is at the first warning level, expand an additional patrol route in the second initial patrol route within the corresponding grid;

[0039] If the grid is at the second warning level, the second initial patrol path within the corresponding grid is repeatedly superimposed;

[0040] If the grid is at the third warning level, the second initial patrol path within the corresponding grid is not adjusted;

[0041] The second initial patrol path after repeated superposition and / or after expanding the additional patrol path is used as the second patrol path.

[0042] By adopting the above technical solution, the second initial patrol path is a coherent closed path passing through all grids. The fire hazard levels of each grid are analyzed based on the historical fire data of the entire target village, and different fire warning levels are assigned. When a grid is assigned the highest-level first warning level, the second initial patrol path within that grid will be expanded with an additional patrol path to increase the patrol range and patrol time of the patrol team within that grid; when a grid is assigned the intermediate-level second warning level, the second initial patrol path within that grid needs to be repeatedly superimposed so that the patrol team patrols back and forth within that grid, thereby increasing the patrol time; when a grid is assigned the lowest-level third warning level, the probability of a fire occurring in that grid is relatively small, and there is no need to adjust the second initial patrol path within that grid. Finally, the second initial patrol path after superposition and / or expansion is used as the second patrol path of the second patrol team.

[0043] Optionally, the data analysis of the historical fire data and the assignment of fire warning levels to each grid according to the data analysis results include the following steps:

[0044] Based on the historical fire data, the total number of fires and the total fire duration within each grid are respectively counted;

[0045] It is respectively determined whether the total fire duration within each grid exceeds a preset duration threshold;

[0046] If it does not exceed the duration threshold, the third warning level is assigned to the corresponding grid;

[0047] If it exceeds the duration threshold, it is determined whether the total number of fires within the corresponding grid exceeds a preset number threshold;

[0048] If it does not exceed the number threshold, the second warning level is assigned to the corresponding grid;

[0049] If it exceeds the number threshold, the first warning level is assigned to the corresponding grid.

[0050] By adopting the above technical solution, the warning levels are assigned to each grid by combining the total number of fires and the total fire duration in the historical fire data. If the total fire duration in the grid is long, it indicates that if a fire occurs in the grid, the disaster impact will be large. Therefore, a preliminary judgment is first made according to the total fire duration and the preset duration threshold. The grids that do not exceed the duration threshold are assigned the third warning level. If the total number of fires in the grid is large, it indicates that the fire occurrence frequency in the grid is high, and it belongs to a grid where fires are likely to occur. Therefore, according to the total number of fires and the preset number threshold, a re-judgment can be made for the grids whose total fire duration exceeds the duration threshold. If both the total number of fires and the total fire duration of the grid exceed the threshold, the fire hazard in this grid is large and key patrol and prevention are required, so it is assigned the first warning level; if only the total fire duration exceeds the threshold, the fire hazard in this grid is relatively large, so it is assigned the second warning level.

[0051] In a second aspect, the present application also provides a GIS-based rural grid fire management system, including a memory, a processor, and a program stored on the memory and executable on the processor. When the program is loaded and executed by the processor, it can implement the GIS-based rural grid fire management method described in the first aspect.

[0052] In a third aspect, the present application also provides a computer-readable storage medium storing a computer program, and when the computer program is executed by a processor, the processor is caused to implement the GIS-based rural grid fire management method described in the first aspect.

[0053] In summary, the present application includes at least one of the following beneficial technical effects:

[0054] 1. Dividing the target rural area into grids is conducive to the partitioned fire management of the target rural area. Generating a patrol path based on the GIS map and adjusting the patrol path according to the historical fire data of the target rural area and the equipment usage time of the fire-fighting equipment. Finally, the first patrol team and the second patrol team can not only inspect the fire-fighting equipment but also conduct key inspections on areas with relatively large fire hazards during the patrol of the target rural area according to the generated patrol path.

[0055] 2. When the grid is assigned to the first warning level of the highest level, the second initial patrol path within the grid will be expanded with additional patrol paths to increase the patrol range and patrol time of the patrol team within the grid; when the grid is assigned to the second warning level of the intermediate level, the second initial patrol path within the grid needs to be repeatedly superimposed so that the patrol team patrols back and forth within the grid, thereby increasing the patrol time; when the grid is assigned to the third warning level of the lowest level, the probability of a fire occurring in the grid is relatively small, and there is no need to adjust the second initial patrol path within the grid. Finally, the superimposed and / or expanded second initial patrol path is used as the second patrol path of the second patrol team. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The following Figures 1-6 further describes the present application in detail.

[0063] An embodiment of the present application discloses a GIS-based rural grid fire management method.

[0064] Referring to Figure 1 , the GIS-based rural grid fire management method includes the following steps:

[0065] 101. Divide the target rural area into multiple grids according to the GIS map of the target rural area, and set fire patrol points for each grid respectively.

[0066] Among them, the target village can be divided into grids according to land attributes, and the land attributes include farmland, residential areas, forest farms, roads, etc.

[0067] 102. Generate the first initial patrol route of the first patrol team for each grid based on the GIS map.

[0068] Among them, the first patrol team is configured with a small number of people, but each grid will correspond to a first patrol team.

[0069] 103. Combine the fire patrol points of all grids and the GIS map to generate the second initial patrol route of the second patrol team.

[0070] Among them, only one second patrol team can be configured.

[0071] 104. Obtain the equipment usage time and historical fire data of all fire-fighting equipment in each grid respectively.

[0072] Among them, establish a communication connection with the fire management system of the target village, and obtain the equipment usage time and historical fire data of all fire-fighting equipment in the target village through the fire management system.

[0073] 105. Adjust the first initial patrol route based on the equipment usage time to obtain the first patrol route.

[0074] 106. Adjust the second initial patrol route based on the historical fire data to obtain the second patrol route.

[0075] 107. Send the first patrol route to the first mobile terminal held by the first patrol team, and send the second patrol route to the second mobile terminal held by the second patrol team.

[0076] Among them, the first patrol team will conduct fire patrol within the corresponding grid according to the first patrol route, and the second patrol team will conduct fire patrol within the target village according to the second patrol route.

[0077] The implementation principle of this embodiment is as follows:

[0078] Dividing the target village into grids is conducive to the zonal fire management of the target village. Generate the first initial patrol route of the first patrol team according to the GIS map. Since the first patrol team patrols within each grid, and the more the equipment usage time of the fire-fighting equipment within the grid, it indicates that the possibility of a fire near the fire-fighting equipment is higher. Therefore, adjust the first initial patrol route according to the equipment usage time, and finally obtain the first patrol route, and send the obtained first patrol route to the first mobile terminal held by the first patrol team, so that the first patrol team conducts patrol according to the first patrol route.

[0079] The second patrol team patrols the entire target village. Therefore, the second initial patrol path is generated according to the fire patrol points set in each grid and the GIS map. Since the second patrol team patrols across grids, the grids with relatively large fire hazards in each grid can be analyzed based on the historical fire data of the target village, so as to adjust the second initial patrol path to obtain the second patrol path, and then the obtained second patrol path is sent to the second mobile terminal held by the second patrol team, so that the second patrol team can patrol according to the second patrol path. Finally, the first patrol team and the second patrol team can not only inspect the fire-fighting equipment during the patrol of the target village according to the generated patrol path, but also conduct key inspections on the areas with relatively large fire hazards.

[0080] In Figure 1 In step 102 of the embodiment shown, the number of fire-fighting equipment is counted in the GIS map, and the path is generated according to the order of the number. Specifically, it is described in detail through Figure 2 the embodiment shown.

[0081] Referring to Figure 2 , generating the first initial patrol path for each grid based on the GIS map includes the following steps:

[0082] 201. Respectively count the number of fire-fighting equipment in each grid through the GIS map.

[0083] 202. Sort all grids based on the number of equipment in the order from more to less to obtain a generation sequence.

[0084] 203. Generate the first initial patrol path of the first patrol team in each grid based on the positions of the fire-fighting equipment in each grid and according to the generation sequence.

[0085] Among them, the first initial patrol path within the grid will pass through all the fire-fighting equipment within the grid.

[0086] The implementation principle of this embodiment is:

[0087] Since the generation process of the first initial patrol path first needs to query the positions of each fire-fighting equipment one by one, and then construct the fire-fighting equipment in the same grid into a set, and generate the first initial patrol path according to the positions of the fire-fighting equipment in the set, the first initial patrol path of the grid with more fire-fighting equipment is generated first, reducing the time spent on querying the positions of the fire-fighting equipment one by one during the subsequent generation of the patrol path, thereby reducing the overall time for generating the first initial patrol paths of all grids.

[0088] In Figure 1In step 103 of the illustrated embodiment, multiple shortest patrol paths are generated by combining fire patrol points and road information, and then the shortest patrol path with the shortest patrol time is selected as the second initial patrol path. Specifically, it is described in detail through Figure 3 the illustrated embodiment.

[0089] Referring to Figure 3 , generating the second initial patrol path by combining fire patrol points and the GIS map includes the following steps:

[0090] 301. Obtain the road information of the target village through the GIS map.

[0091] 302. Generate multiple shortest patrol paths with each fire patrol point as the starting and ending points and combining the road information.

[0092] Among them, the shortest patrol path is a closed-loop path and passes through all fire patrol points.

[0093] 303. Calculate the patrol time required for the second patrol team to patrol one circle in each of the shortest patrol paths according to the preset patrol speed.

[0094] 304. Select the shortest patrol path corresponding to the shortest patrol time as the second initial patrol path of the second patrol team.

[0095] The implementation principle of this embodiment is:

[0096] First, take any one of the multiple fire patrol points as the starting and ending points, and generate all feasible shortest patrol paths by combining the road information. Since the rural roads may be relatively complex, all the generated shortest patrol paths may be different. Therefore, it is necessary to calculate the patrol time required for each shortest patrol path to patrol one circle according to the preset same patrol speed, and then select the shortest patrol path with the shortest patrol time as the second initial patrol path.

[0097] In Figure 1 step 105 of the illustrated embodiment, the fire-fighting equipment in the grid is classified and marked according to the equipment usage time of the fire-fighting equipment in the grid, and then the number of important fire-fighting equipment is counted. Based on the number of important fire-fighting equipment, it is judged whether the path needs to be adjusted. Specifically, it is described in detail through Figure 4 the illustrated embodiment.

[0098] Referring to Figure 4 , adjusting the first initial patrol path based on the equipment usage time includes the following steps:

[0099] 401. Based on a preset usage time threshold, judge the equipment usage time of the fire-fighting equipment passed by in the first initial patrol path, and determine whether the equipment usage time of the passed fire-fighting equipment is greater than the usage time threshold. If it is greater, execute step 402; if it is not greater, execute step 403.

[0100] 402. Mark the corresponding passed fire-fighting equipment as important fire-fighting equipment.

[0101] 403. Mark the corresponding passed fire-fighting equipment as secondary fire-fighting equipment.

[0102] 404. Count the number of important fire-fighting equipment passed by in the first initial patrol path.

[0103] 405. Determine whether the number of important fire-fighting equipment exceeds the preset quantity threshold. If it exceeds, execute step 406; if it does not exceed, execute step 407.

[0104] 406. Extend the first initial patrol path based on the positions of all important fire-fighting equipment to obtain the first patrol path.

[0105] Among them, in the first patrol path, any important fire-fighting equipment is passed at least twice.

[0106] 407. Do not adjust the first initial patrol path, and use the first initial patrol path as the first patrol path.

[0107] The implementation principle of this embodiment is as follows:

[0108] Classify the fire-fighting equipment in the same grid according to the equipment usage time of the fire-fighting equipment. Mark the fire-fighting equipment with an equipment usage time greater than the time threshold as important fire-fighting equipment, while mark the fire-fighting equipment with an equipment usage time not greater than the time threshold as secondary fire-fighting equipment. After classifying the fire-fighting equipment, count the number of important fire-fighting equipment. If the number of important fire-fighting equipment is small and lower than the preset quantity threshold, it means that the utilization rate of the fire-fighting equipment in this grid is not high, and it is not necessary to conduct key inspections on all important fire-fighting equipment; if the number of important fire-fighting equipment is large and higher than the preset quantity threshold, it means that the utilization rate of the fire-fighting equipment in this grid is relatively high. Therefore, it is necessary to extend and adjust the first initial patrol path according to the positions of the important fire-fighting equipment in this grid to obtain the first patrol path, so that the first patrol team can inspect all important fire-fighting equipment at least twice when patrolling according to the first patrol path.

[0109] In Figure 1 step 106 of the illustrated embodiment, allocate the fire warning level of the grid according to the historical fire data, and make corresponding path adjustments to each grid according to the different fire warning levels. It is specifically described in detail through Figure 5 the illustrated embodiment.

[0110] Referring to Figure 5 , the path adjustment of the second initial patrol path based on historical fire data includes the following steps:

[0111] 501. Analyze the historical fire data, and assign fire warning levels to each grid according to the analysis results of the data.

[0112] Among them, the fire warning levels include the first warning level, the second warning level, and the third warning level. The first warning level is greater than the second warning level, and the second warning level is greater than the third warning level.

[0113] 502. Respectively judge the fire warning levels of each grid. If the grid is at the first warning level, execute step 503; if the grid is at the second warning level, execute step 504; if the grid is at the third warning level, execute step 505.

[0114] 503. Expand the additional patrol path in the second initial patrol path within the corresponding grid.

[0115] 504. Repeat and superimpose the second initial patrol path within the corresponding grid.

[0116] 505. Do not adjust the second initial patrol path within the corresponding grid.

[0117] 506. Use the second initial patrol path after repeated superimposition and / or after expanding the additional patrol path as the second patrol path.

[0118] The implementation principle of this embodiment is as follows:

[0119] The second initial patrol path is a continuous closed path passing through all grids. Analyze the degree of fire hazards of each grid according to the historical fire data of the entire target village, and assign different fire warning levels. When a grid is assigned the highest first warning level, the additional patrol path will be expanded in the second initial patrol path within the grid to increase the patrol range and patrol time of the patrol team within the grid; when a grid is assigned the intermediate second warning level, the second initial patrol path within the grid needs to be repeatedly superimposed so that the patrol team patrols back and forth within the grid, thereby increasing the patrol time; when a grid is assigned the lowest third warning level, the probability of a fire occurring in this grid is relatively small, and there is no need to adjust the second initial patrol path within the grid. Finally, use the second initial patrol path after superimposition and / or expansion as the second patrol path of the second patrol team.

[0120] In Figure 5In step 501 of the illustrated embodiment, the historical fire data includes the fire location, the number of fires, and the fire duration of each fire in the history of the target village. Through data analysis, the historical fire situation of each grid can be analyzed, and then the corresponding fire warning levels can be assigned. Specifically, it is described in detail through Figure 6 the illustrated embodiment.

[0121] Referring to Figure 6 , the data analysis of the historical fire data and the assignment of fire warning levels to each grid include the following steps:

[0122] 601. Based on the historical fire data, respectively count the total number of fires and the total fire duration in each grid.

[0123] Among them, determine the grid where the fire location of each fire is located, so as to count the total number of fires in each grid, and then add up the fire durations of all the fires that have occurred in each grid to obtain the total fire duration in the grid.

[0124] 602. Respectively judge whether the total fire duration in each grid exceeds the preset duration threshold. If it does not exceed, execute step 603; if it exceeds, execute step 604.

[0125] 603. Assign the third warning level to the corresponding grid.

[0126] 604. Judge whether the total number of fires in the corresponding grid exceeds the preset number threshold. If it does not exceed, execute step 605; if it exceeds, execute step 606.

[0127] 605. Assign the second warning level to the corresponding grid.

[0128] 606. Assign the first warning level to the corresponding grid.

[0129] The implementation principle of this embodiment is:

[0130] Combined with the total number of fires and the total duration of fires in historical fire data, warning levels are assigned to each grid. If the total duration of fires in a grid is long, it indicates that if a fire occurs in this grid, the disaster impact will be large. Therefore, a preliminary judgment is first made based on the total duration of fires and a preset duration threshold. Grids that do not exceed the duration threshold are assigned the third warning level. If the total number of fires in a grid is large, it means that the fire occurrence frequency in this grid is high and it belongs to a grid prone to fires. Therefore, based on the total number of fires and a preset number threshold, a re-judgment can be made for grids where the total duration of fires exceeds the duration threshold. If both the total number of fires and the total duration of fires in a grid exceed the threshold, the fire hazard in this grid is large and key patrol and prevention are required, so it is assigned the first warning level; if only the total duration of fires exceeds the threshold, the fire hazard in this grid is relatively large, so it is assigned the second warning level.

[0131] The embodiment of the present application also discloses a lithium battery pack charge and discharge management system, including a memory and a processor. The memory stores a program that can be run on the processor to implement as Figures 1 to 6 any one of the GIS-based rural grid fire management methods.

[0132] The embodiment of the present application also discloses a computer-readable storage medium storing a computer program. When the computer program is executed by the processor, the processor is enabled to implement Figures 1 to 6 the GIS-based rural grid fire management method shown in

[0133] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
