The corresponding maintenance strategies are generated according to the damaged state of different vegetation in each maintenance area and sent to the corresponding maintenance personnel.

[0055] Embodiment 1

[0056] Please refer to Figure 1, is a flow chart of a maintenance method of a smart garden provided by an embodiment of the present invention, comprising the following specific steps:

[0057] S1. Obtaining the current vegetation information of each maintenance area after being damaged; wherein, several types of vegetation are planted in each maintenance area, and a maintenance area is divided into several corresponding local areas according to the planting range of each type of vegetation; the current vegetation information includes: soil temperature and soil moisture of each local area at several time nodes;

[0058] Specifically, since the garden area is large and there are many types of vegetation, the present invention divides the garden into multiple maintenance areas for refined maintenance management. In order to maintain the stability of the ecosystem in an area, generally multiple types of vegetation are planted in each maintenance area, and different types of vegetation have different growth characteristics and need different maintenance methods. Therefore, in order to facilitate maintenance, in each maintenance area, according to the planting range of different types of vegetation, the maintenance area is further subdivided into different local areas, and different maintenance methods are set for each local area according to the growth characteristics of the vegetation types in the local area.

[0059] After extreme weather phenomena such as heavy rain, typhoons and snowstorms occur, the vegetation in the garden will suffer varying degrees of serious damage. At this time, it is no longer possible to carry out daily maintenance according to the daily maintenance process. It is necessary to activate the emergency maintenance plan described in the present invention to ensure the orderly development of garden maintenance work after extreme weather.

[0060] In vegetation management, soil temperature and soil moisture are important factors affecting vegetation growth. Changes in soil moisture and soil temperature can most directly reflect the current health of vegetation. When extreme weather phenomena occur and damage vegetation, the soil temperature and soil moisture in the area where the vegetation is located will change significantly, far exceeding the changes in soil temperature and soil moisture of vegetation under normal weather conditions. For example, when it rains normally, although the soil temperature and soil moisture in the area where the vegetation is located will also change, the change range is not large. We can set a normal range of soil temperature and soil moisture, and judge whether the vegetation is damaged and the extent of the damage according to whether the soil temperature and soil moisture in the area where the vegetation is located exceeds this normal range and the value exceeding this normal range. When extreme weather phenomena such as heavy rain occur, the soil temperature and soil moisture in the area where the vegetation is located will change significantly, far exceeding the normal range of soil temperature and soil moisture. At this time, the soil temperature and humidity collected after the heavy rain can be compared with the set soil temperature and humidity range under normal conditions to evaluate the degree of damage to the vegetation caused by heavy rain.

[0061] Therefore, the present invention uses soil temperature and soil moisture as analysis indicators, and compares the soil temperature and humidity after vegetation damage with the standard range of soil temperature and humidity before vegetation damage to evaluate the damage type and degree of vegetation. In the maintenance area, we need to set at least one measuring point in each local area, and install a temperature sensor and a humidity sensor at the measuring point. After extreme weather phenomena occur, the temperature sensor data and humidity sensor data of the measuring point are collected in time to reflect the soil temperature and soil moisture of the vegetation in the local area. And because the soil temperature value and soil moisture value of the same measuring point are different in different time periods of the same day, if only a single soil temperature value and soil moisture value are collected, the data support is not high, so it is also necessary to set multiple time nodes to collect the soil temperature and soil moisture of each local area at each time node.

[0062] S2. For each maintenance area, the soil moisture of each local area at a number of time nodes is compared with the standard soil moisture range at each corresponding time node when the vegetation in the local area is not damaged, to obtain a first comparison result;

[0063] Preferably, the soil moisture of each local area at a number of time nodes is compared with the standard soil moisture range at each corresponding time node when the vegetation in the local area is not damaged to obtain a first comparison result, including: numbering each local area in sequence, and constructing a corresponding spatial rectangular coordinate system with the number corresponding to the local area as the X-axis, time as the Y-axis, and soil moisture as the Z-axis; projecting the soil moisture of each local area at a number of time nodes into the spatial rectangular coordinate system according to the number corresponding to each local area, to obtain a corresponding first spatial rectangular coordinate system; and projecting the soil moisture of each local area at a number of time nodes into the spatial rectangular coordinate system according to the number corresponding to each local area. , projecting the standard soil moisture range at each corresponding time node when the vegetation in each local area is not damaged into the spatial rectangular coordinate system to obtain the corresponding second spatial rectangular coordinate system; superimposing the first spatial rectangular coordinate system and the second spatial rectangular coordinate system to obtain overlapping information between the first spatial rectangular coordinate system and the second spatial rectangular coordinate system, and then determining a first comparison result between the soil moisture of the vegetation in the local area at the same time node and the corresponding standard soil moisture range according to the overlapping information between the first spatial rectangular coordinate system and the second spatial rectangular coordinate system.

[0064] Specifically, after collecting the soil moisture and soil temperature of each local area at different time nodes, since there are multiple local areas in a maintenance area, each local area will collect temperature and humidity data at multiple time nodes. The data comparison process is cumbersome and prone to errors. Therefore, the present invention first numbers the local areas in the maintenance area, and constructs a spatial rectangular coordinate system with the number corresponding to the local area as the X-axis, time as the Y-axis, and soil moisture as the Z-axis.

[0065] Then, according to the corresponding number of each local area, the soil moisture of each local area at each time node is projected into the spatial rectangular coordinate system to obtain the corresponding first spatial rectangular coordinate system, and the standard soil moisture range at each corresponding time node when the vegetation in each local area is not damaged is projected into the spatial rectangular coordinate system to obtain the corresponding second spatial rectangular coordinate system. In the first spatial rectangular coordinate system, for each local area, its soil moisture at each time node will present a projection point in the first spatial rectangular coordinate system, and finally form multiple projection points in the first spatial rectangular coordinate system, each projection point represents the soil moisture of a local area at a time node. In the second spatial rectangular coordinate system, since the soil moisture on the Z axis is a range value, for each local area, its standard soil moisture range at each time node will present a projection straight line in the second spatial rectangular coordinate system, and finally form multiple projection straight line points in the first spatial rectangular coordinate system, each projection straight line represents the standard soil moisture range of a local area at a time node.

[0066] Then the first spatial rectangular coordinate system and the second spatial rectangular coordinate system are superimposed, and the first comparison result between the soil moisture and the corresponding standard soil moisture range is obtained by comparing the overlap degree of the projection point and the projection line in the spatial rectangular coordinate system after superposition. Among them, after the first spatial rectangular coordinate system and the second spatial rectangular coordinate system are superimposed, the projection point and the projection line divide the superimposed spatial rectangular coordinate system into multiple YOZ planes with the area number of each local area as the segmentation point. In each YOZ plane, there are projection points corresponding to the soil moisture of a single local area at different time nodes, and projection lines corresponding to the quasi-soil moisture range. Then, it is checked whether the projection point at the same time node in the YOZ plane falls within the range of the projection line, and whether the soil moisture at each time node is within the standard soil moisture range is judged. If the soil moisture at multiple time nodes is within the standard soil moisture range, it means that the vegetation has not been damaged. If the soil moisture at multiple time nodes is not within the standard soil moisture range, it means that the vegetation has been damaged, and the degree of damage is judged according to the distance between the projection point and the projection line.

[0067] S3, comparing the soil temperature of each local area at a number of time nodes with the standard soil temperature range at each corresponding time node when the vegetation in the local area is not damaged, to obtain a second comparison result, and then determining the damage type and degree of the corresponding type of vegetation in each local area according to the first comparison result and the second comparison result;

[0068] Preferably, the soil temperature of each local area at several time nodes is compared with the standard soil temperature range at each corresponding time node when the vegetation in the local area is not damaged to obtain a second comparison result, including: according to the corresponding number of each local area, the soil temperature of each local area at several time nodes is projected into the spatial rectangular coordinate system to obtain a corresponding third spatial rectangular coordinate system; according to the corresponding number of each local area, the standard soil temperature range at each corresponding time node when the vegetation in each local area is not damaged is projected into the spatial rectangular coordinate system to obtain a corresponding fourth spatial rectangular coordinate system; the third spatial rectangular coordinate system and the fourth spatial rectangular coordinate system are superimposed to obtain overlapping information between the third spatial rectangular coordinate system and the fourth spatial rectangular coordinate system, and then according to the overlapping information between the third spatial rectangular coordinate system and the fourth spatial rectangular coordinate system, a second comparison result between the soil temperature of the vegetation in the local area at the same time node and the corresponding standard soil temperature range is determined.

[0069] Specifically, the soil temperature and soil moisture are similar. According to the corresponding number of each local area, the soil temperature of each local area at different time nodes is projected into the spatial rectangular coordinate system to obtain the corresponding third spatial rectangular coordinate system. The standard soil temperature range at different time nodes when the vegetation in each local area is not damaged is projected into the spatial rectangular coordinate system to obtain the corresponding fourth spatial rectangular coordinate system. Then the third spatial rectangular coordinate system and the fourth spatial rectangular coordinate system are superimposed to obtain a comparison result. If the soil temperature at multiple time nodes is within the standard soil temperature range, it means that the vegetation has not been damaged. If the soil temperature at multiple time nodes is not within the standard soil moisture range, it means that the vegetation has been damaged, and the degree of damage is judged according to the distance between the projection point and the projection line.

[0070] Among them, the types of vegetation damage are: undamaged and damaged. After obtaining the vegetation damage type and damage degree under the two analysis indicators of soil moisture and soil temperature, as long as the vegetation damage type under one analysis indicator is damaged, it can be judged that the vegetation in the local area is damaged. Then the damage degree under the two analysis indicators is weighted and summed to obtain the overall vegetation damage degree in the local area.

[0071] S4. According to the damage type and degree of the corresponding type of vegetation in each local area, the local maintenance strategy of each local area is matched, and the local maintenance strategies of each local area are integrated to obtain the overall maintenance strategy of the maintenance area;

[0072] Specifically, for a maintenance area, after obtaining the damage type and degree of damage of the corresponding type of vegetation in each local area, the local maintenance strategy of each local area can be matched according to its damage type and degree. In a local area, if its damage type is undamaged, it means that the soil temperature and soil moisture in the local area are within the normal range, and the extreme weather has not damaged the vegetation in the local area. There is no need to match the local maintenance strategy in an emergency situation. After the maintenance of other damaged areas is completed, it can be maintained according to its daily maintenance plan. If its damage type is damaged, it means that the soil temperature and soil moisture in the local area exceed the normal range, and the extreme weather has caused damage to the vegetation in the local area. At this time, according to its damage degree and the preset local maintenance strategy of this type of vegetation at different damage degrees, the corresponding local maintenance strategy is matched. Finally, the local maintenance strategies of each local area are integrated to obtain the overall maintenance strategy of the maintenance area.

[0073] For example, the degree of vegetation damage can be divided into three categories: mild, moderate and severe. Mild damage usually does not affect the overall growth of vegetation, and can be restored naturally, reducing human intervention and allowing vegetation to recover on its own. Moderate damage requires appropriate human intervention to promote vegetation recovery. Severe damage requires comprehensive control measures, including reafforestation, soil and water conservation, ecological reconstruction, etc., to completely restore the functions of the ecosystem.

[0074] If the degree of damage to the vegetation is slight, emergency maintenance will not be carried out on the vegetation in the local area, and daily maintenance can be carried out according to the original daily maintenance plan. If the degree of damage to the vegetation is moderate, it is necessary to match the emergency maintenance plan corresponding to the type of vegetation in the local area and carry out emergency maintenance according to the emergency situation. We will formulate appropriate restoration and maintenance measures in advance according to the vegetation type and regional characteristics. For example, bare land can be repaired by covering the soil, planting pioneer plants, etc. For contaminated land, pollutants need to be removed and soil improved. When it is determined that the vegetation is moderately damaged, the corresponding restoration and maintenance strategy will be matched according to the vegetation type. If the degree of damage to the vegetation is severe, it needs to be reported to the relevant management department, and then professional staff will carry out management, reforestation, soil and water conservation, and ecological reconstruction.

[0075] S5. Generate a maintenance plan for each maintenance area according to the overall maintenance strategy of each maintenance area, and send the maintenance plan to the corresponding maintenance personnel, so that the corresponding maintenance personnel maintain each maintenance area according to the maintenance plan of each maintenance area.

[0076] Preferably, the current vegetation information also includes: a vegetation image of the entire maintenance area; before generating a maintenance plan for each maintenance area based on the overall maintenance strategy of each maintenance area, it also includes: analyzing the vegetation image to obtain the vegetation coverage rate in each maintenance area, and determining the vegetation damage level in each maintenance area based on the vegetation coverage rate, and then determining the maintenance order of each maintenance area based on the vegetation damage level.

[0077] Preferably, the vegetation image is analyzed to obtain the vegetation coverage rate in each maintenance area, including: preprocessing the vegetation image; wherein the preprocessing includes: image denoising, light correction and color distortion processing; according to a preset image segmentation algorithm, the preprocessed vegetation image is segmented to obtain a number of segmented areas; wherein the image segmentation algorithm includes: an edge detection algorithm and a region growing algorithm; extracting features of each segmented area; wherein the features include: color, texture and shape; according to the features of each segmented area, the pixels in each segmented area are divided into vegetation pixels and non-vegetation pixels; counting the number of pixels belonging to vegetation pixels in all segmented areas, as well as the total number of pixels of vegetation pixels and non-vegetation pixels, and then calculating the vegetation coverage rate in each maintenance area based on the number of pixels and the total number of pixels.

[0078] Preferably, the method of determining the vegetation damage level in each area according to the vegetation coverage rate, and then determining the maintenance order of each maintenance area according to the vegetation damage level, includes: comparing the vegetation coverage rate in each maintenance area with the preset vegetation coverage rate range of each vegetation damage level to determine the vegetation damage level in each maintenance area; and determining the maintenance order of each maintenance area according to the vegetation damage level in each maintenance area in descending order of the vegetation damage level.

[0079] Preferably, the maintenance plan for each maintenance area is generated according to the overall maintenance strategy of each maintenance area, and the maintenance plan is sent to corresponding maintenance personnel so that the corresponding maintenance personnel maintain each maintenance area according to the maintenance plan of each maintenance area, including: generating a maintenance plan for each maintenance area according to the overall maintenance strategy and maintenance sequence of each maintenance area, and sending the maintenance plan to corresponding maintenance personnel in the maintenance sequence of each maintenance area, so that the corresponding maintenance personnel maintain each maintenance area according to the maintenance plan of each maintenance area.

[0080] Specifically, after obtaining the overall maintenance strategy of each maintenance area, it is also necessary to obtain the overall vegetation image of the maintenance area, and then analyze the vegetation image to obtain the vegetation coverage rate in each maintenance area, and then determine the vegetation damage level in each maintenance area according to the vegetation coverage rate. Several vegetation coverage rate ranges and the vegetation damage level corresponding to each vegetation coverage rate range are set in advance, and then the vegetation coverage rate in the maintenance area is compared with the preset vegetation coverage rate range of each vegetation damage level to determine the vegetation damage level in each maintenance area, and then the maintenance order of each maintenance area is determined in order from high to low according to the vegetation damage level. Then, according to the overall maintenance strategy and maintenance order of each maintenance area, a maintenance plan for each maintenance area is generated, and the maintenance plan is sent to the corresponding maintenance personnel according to the maintenance order of each maintenance area, so that the corresponding maintenance personnel can maintain each maintenance area according to the maintenance plan of each maintenance area.

[0081] The present invention calculates the vegetation coverage rate in each maintenance area, so as to roughly understand the severity of damage in each maintenance area, and sorts the maintenance order of each maintenance area according to the severity of damage in each maintenance area, and gives priority to maintenance of maintenance areas with higher damage severity, which can greatly avoid the situation where there is a shortage of manpower and unreasonable personnel scheduling, resulting in maintenance areas with higher damage severity not being maintained in time, thereby causing irreparable losses.
