However, since the roof garden is set up on the roof of the building, which is different from the ground soil, when the plants are watered too much, water will accumulate on the roof, causing the waterproof material to be soaked in water for a long time, resulting in a reduced lifespan, thereby forming a situation such as roof leakage. Or when the plants are watered too little, it will cause the plants to lack water, affecting the normal growth of the plants, and the practicality is not high. To solve this problem, the present invention proposes a plant management method for watering the plants in an appropriate amount according to the actual situation of the plants in the roof garden, thereby improving the practical value of the roof garden. First, by laying a preset number of A humidity sensor is used to monitor the humidity of the green plant soil in the roof garden in real time, determine the first humidity of each block of green plant soil, and judge whether the corresponding first humidity meets the standard according to the basic growth requirements of the plants on each block of green plant soil, and obtain a judgment result; it is worth noting that the present invention mainly describes the use of rainwater in sponge cities, and realizes the migration of rainwater in the city by collecting rainwater for irrigation.

[0021] See also Figure 2 In one embodiment, a preset number of humidity sensors are laid on the roof garden to monitor the first humidity of the soil of the green plants in the roof garden in real time, including: S201. Manage the green plant soil in the roof garden in blocks according to the soil block management standard; wherein each soil block has a unique soil number, and the green plants planted in each soil block belong to the same category; S202, according to the area of ​​each soil block and based on the detection performance of the humidity sensor, a preset number of humidity sensors are laid in advance in each soil block of the roof garden; wherein a corresponding number of humidity sensors are evenly laid in each soil block; S203, obtaining a first humidity of each soil block by averaging the detection data of all humidity sensors in each soil block; The working principle of the above technical solution is: in order to realize accurate monitoring of the soil moisture of green plants in the roof garden, the present application performs block management on the green plant soil in the roof garden according to the soil block management standard, wherein the soil block standard is preferably a unified classification management of the same green plants, that is, the green plants planted on each soil block belong to the same category, and each soil block is complete and continuous, and has a unique soil number. It is worth noting that when the proportion of green plants of the same category in a soil block exceeds 95%, it is considered that the green plants planted on the soil block belong to this category; then according to the area of ​​each soil block and based on the detection performance of the humidity sensor, the green plants planted on the roof A preset number of humidity sensors are laid in advance in each soil block of the garden; wherein a corresponding number of humidity sensors are evenly laid in each soil block, and the number of humidity sensors laid in each soil block is related to the area of ​​the soil block and the detection performance of the humidity sensor. The larger the area of ​​the soil block, the more humidity sensors are laid, the better the detection performance of the humidity sensor, and the fewer humidity sensors are laid; finally, the first humidity of each soil block is obtained by averaging the detection data of all humidity sensors in each soil block, and the method of using the average value as the monitoring result can determine the overall trend of the first humidity of the green plants in each block; The beneficial effect of the above technical solution is: through the above technical solution, the block monitoring method is adopted to complete the accurate monitoring of the soil moisture in each piece of green plant soil in the roof garden, which is beneficial to improving the efficiency of green plant management in the subsequent garden.

[0022] In one embodiment, determining whether the first humidity meets the basic growth requirements of green plants and obtaining a determination result includes: Obtain the types of green plants planted in each soil block in the roof garden, and call the basic growth requirements of the corresponding green plant types through the database; wherein the basic growth requirements are growth humidity requirements; Obtaining a first humidity of each block of soil, determining whether the first humidity meets the basic growth requirements of the corresponding green plant, and obtaining a determination result; wherein the determination result includes whether the first humidity meets the basic growth requirements of the corresponding green plant, and whether the first humidity does not meet the basic growth requirements of the corresponding green plant; The working principle of the above technical solution is as follows: Since the present invention is mainly used for plant management in roof gardens for sponge cities, when judging whether the current environment meets the basic growth requirements of green plants, the concept of rainwater migration in sponge cities is taken into consideration, and only the water growth requirements of green plants, that is, the humidity requirements, are restricted. There are many ways to judge other growth parameters such as fertilizers and light in the prior art, which will not be described in detail here; in the specific judgment, first obtain the types of green plants planted in each soil block in the roof garden, and call the basic growth requirements of the corresponding green plant types through the database. It can be seen from the above description that the basic growth requirements include growth humidity requirements, and then judge whether the first humidity of each soil block is Whether it meets the basic growth requirements of the corresponding green plants, a judgment result is obtained; wherein, the first humidity does not meet the basic growth requirements of the corresponding green plants, including that the first humidity of the block soil is greater than the basic growth requirements of the corresponding green plants, and the first humidity of the block soil is less than the basic growth requirements of the corresponding green plants; when the judgment result is that the first humidity of the block soil is greater than the basic growth requirements of the corresponding green plants, it will cause water to overflow from the soil and cause the soil permeability to be destroyed; when the first humidity of the block soil is less than the basic growth requirements of the corresponding green plants, it will cause water deficiency and thus cause water stress; when the judgment result is that the first humidity of the block soil meets the basic growth requirements of the corresponding green plants, it is the best state; The beneficial effects of the above technical scheme are: through the above technical scheme, the classification of green plants is refined, and the moisture content of the green plant soil on each soil block is judged separately. Corresponding judgment conditions are used for different types of green plants for differentiated judgment. Compared with the overall judgment of the moisture requirements of the entire piece of soil, it is beneficial to improve the judgment accuracy of the basic growth requirements of green plants, thereby improving the subsequent green plant management efficiency in the garden.

[0023] In one embodiment, obtaining the types of green plants planted in each soil block in the roof garden and calling the basic growth requirements of the corresponding green plant types through the database also includes: Obtain the types of green plants planted in each soil block in the roof garden, and collect images of the green plants in each soil block through an image acquisition device; Identify the growth stage of each green plant image, and call the basic growth requirements of the corresponding green plants through the database according to the growth stage and green plant type; The working principle of the above technical solution is as follows: in order to further improve the determination of the growth requirements of green plants, this solution preferably distinguishes the growth stages of the green plant types in each green plant soil block, first obtains the green plant types planted in each soil block in the roof garden, and collects the green plant images of each soil block through the image acquisition device, and then identifies the growth stage of each green plant image. During the identification process, since the green plants on each soil block are green plants of the same category, the green plant images of multiple green plants on each soil block are randomly obtained as collection samples, and the identification features corresponding to the growth stages of the green plants are called for the collection samples, and the growth stages of the multiple collection samples are identified according to the identification features, and finally multiple identification results are obtained, and the basic growth requirements corresponding to the growth stages in all different identification results are obtained (preferably the humidity growth requirements in this solution), and the average value is calculated to obtain an average humidity growth range, and the humidity growth range is matched with the basic growth requirements of each growth stage of the current green plant category, and the growth stage with the highest similarity of the humidity growth range is obtained, and the growth stage is determined to be the growth stage of the current green plant image, and finally the basic growth requirements of the corresponding green plants are called through the database according to the growth stage and the green plant type; The beneficial effect of the above technical solution is: through the above technical solution, the reliability of the basic growth requirements obtained is improved, which is beneficial to enhancing the efficiency of subsequent green plant management in the garden.

[0024] See also Figure 3 In one embodiment, according to the judgment result, combined with the waterproof performance of the roof material, the drainage efficiency of the drainage device and the predicted weather data, the control management device performs a humidification operation or a dehumidification operation on the soil, including: S301, obtaining the judgment result of any soil block; S302: If the judgment result is that the first humidity of the current block of soil meets the basic growth requirements of the corresponding green plant, the control management device continues to standby; S303: If the judgment result is that the first humidity of the current block soil does not meet the basic growth requirements of the corresponding green plants, obtain the predicted weather data, the waterproof performance of the roof material and the drainage efficiency of the drainage device, and generate a humidification strategy or a dehumidification strategy; S304, the control management device performs corresponding operations on the current block of soil according to the humidification strategy or the dehumidification strategy; When the management device receives the humidification strategy, the management device is controlled to intelligently water the current block of soil according to the humidification strategy; When the management device receives the dehumidification strategy, the management device is controlled to discharge corresponding hygroscopic substances according to the dehumidification strategy to reduce the soil moisture of the current block of soil; The working principle of the above technical solution is: in order to achieve precise control of soil moisture for green plants, this solution preferably combines the waterproof performance of roof materials, the drainage efficiency of drainage devices and predicted weather data, and controls the management equipment to perform humidification or dehumidification operations on the soil, so as to reasonably regulate the soil moisture so that it can meet the basic growth requirements of green plants while preventing the soil moisture from causing greater impact on the roof. To achieve the above purpose, taking any block of soil as an example, it is first necessary to obtain the judgment result of any block of soil. When the judgment result is that the first humidity of the current block of soil meets the basic growth requirements of the corresponding green plants, no operation is performed, that is, the control management equipment continues to be in standby state; when the judgment result is that the first humidity of the current block of soil is greater than or less than the corresponding When the basic growth requirements of green plants are met, the predicted weather data, the waterproof performance of the roof materials and the drainage efficiency of the drainage device are obtained, and a dehumidification strategy or a humidification strategy is generated based on these data. The management device is controlled to discharge the corresponding hygroscopic substances according to the dehumidification strategy to reduce the soil moisture of the current block of soil. When the management device receives the humidification strategy, the management device is controlled to perform intelligent watering on the current block of soil according to the humidification strategy; so that it can combine weather data and drainage efficiency to maintain humidity balance for a period of time in the future. The humidity balance refers to the balance between the humidity requirements for green plant growth and the humidity requirements for roof waterproof materials; further, soil permeability can also be considered during humidification and dehumidification operations, which is beneficial to improve the accuracy of humidification and dehumidification strategies and achieve more accurate humidity management; The beneficial effects of the above technical scheme are: through the above technical scheme, the soil moisture can be reasonably regulated to meet the basic growth requirements of green plants while preventing the soil moisture from causing greater impact on the roof. Compared with the quantitative watering method of the existing watering scheme, the waterproof performance of the roof material, the drainage efficiency of the drainage device and the predicted weather data are combined to achieve precise control of the soil moisture of green plants.

[0025] In one embodiment, if the judgment result is that the first humidity of the current block soil does not meet the basic growth requirements of the corresponding green plants, the predicted weather data, the waterproof performance of the roof material and the drainage efficiency of the drainage device are obtained, and a humidification strategy or a dehumidification strategy is generated, including: If the judgment result is that the first humidity of the current sub-block soil does not meet the basic growth requirements of the corresponding green plant, obtain the specific reason for the non-compliance; If the specific reason for non-compliance is that the first humidity of the current sub-block soil is greater than the basic growth requirement of the corresponding green plants, the forecast weather data is obtained through the meteorological database receiving device, and the waterproof performance of the roof material and the drainage efficiency of the drainage device arranged in the roof garden pre-stored in the database are called; The total rainfall and total soil moisture usage at each moment in the future preset time period are calculated based on the predicted weather data and the corresponding green plant information; the total soil moisture usage includes soil moisture evaporation and soil plant absorption and consumption; The net value of rainwater content at each moment is calculated by subtracting the total rainfall from the total soil moisture usage; Predicting the change trend curve of the first moisture of the soil in each block at each moment in the future preset time period without human interference based on the net value of rainwater content and the drainage efficiency of the drainage device; According to the trend curve, based on the optimal humidity range of the roof material's waterproof performance and the basic growth requirements of green plants, a dehumidification strategy for the corresponding time node is generated; If the specific reason for not meeting the requirement is that the first humidity of the current sub-block soil is less than the basic growth requirement of the corresponding green plant, the net value of rainwater content at each moment in the future preset time period is obtained, and a second change trend curve of the first humidity of the sub-block soil at each moment in the future preset time period is predicted based on the net value of rainwater content without human interference; According to the second change trend curve, based on the optimal humidity range of the waterproof performance of the roof material and the basic growth requirements of the green plants, a humidification strategy for the corresponding time node is generated; The working principle of the above technical solution is as follows: at present, when watering the plants on the roof garden, a timed and quantitative watering method is still used to water the plants. However, since the roof garden is set up on the roof of the building, which is different from the ground soil, when the plants are watered too much, water will accumulate on the roof, causing the waterproof material to be soaked in water for a long time, resulting in a reduced lifespan, thereby forming a situation such as roof leakage. Or when the plants are watered too little, it will cause the plants to lack water, affecting the normal growth of the plants, and the practicality is not high. To solve the above problems, when the first humidity of the current block soil is greater than the basic growth requirement of the corresponding green plants, the predicted weather data, including weather conditions, temperature and humidity, rainfall and other information, is first obtained through the meteorological data receiving device. The weather data can also be obtained through the online API service, and then the waterproof performance parameters of the current roof material and the drainage efficiency data of the drainage device installed in the roof garden pre-stored in the database are called. These The data is provided by the developer and the corresponding installation and construction department; and the total rainfall and total soil moisture usage in the future preset time period are calculated based on the predicted weather data and the corresponding green plant information. The total rainfall can be calculated based on the predicted weather data for the time period, and the total soil moisture usage includes soil moisture evaporation and soil plant absorption and consumption. The calculation of soil moisture evaporation can be determined by parameters such as VM (maximum water storage capacity of the basin), K (recession coefficient) and Pa (previous rainfall impact). The specific calculation method already has the corresponding existing technology, which will not be repeated here. The soil plant absorption and consumption is preferably estimated and predicted based on the plant water demand in the time period. The specific plant water demand is determined based on the type of soil plants. It is worth noting that the plant water demand data of the plants planted in the roof garden have all been pre-stored in the database waiting to be called, and there are differences in water demand in different growth cycles.After calculating the total rainfall and the total soil moisture usage in the future preset time period, the net rainwater content at each moment is calculated by subtracting the total rainfall and the total soil moisture usage. It is worth noting that the net rainwater content is a variable, which changes with time, that is, in the future preset time period, the total rainfall at each moment is a variable, and the total soil moisture usage from the start of calculation to the current moment is also a variable. Therefore, it can be seen that the net rainwater content has different values ​​at different moments. According to the net rainwater content and combined with the drainage efficiency of the drainage device, a change trend curve of the first humidity of the divided soil in the future preset time period without human interference is predicted. The horizontal axis of the change trend curve represents time, and the vertical axis represents the humidity change. Among them, the drainage efficiency of the drainage device usually only drains the soil overflow moisture and the moisture near the soil. The drainage treatment of the soil overflow moisture is mainly used to reduce the water storage capacity of the watershed formed by the soil, and the drainage treatment of the moisture near the soil is mainly used to reduce the water storage content near the soil, which is used as the total soil moisture usage. The additional amount of money spent is used to accurately calculate the net value of rainwater content, so as to make a more accurate judgment on the first humidity of the block soil; finally, according to the optimal humidity range of the waterproof performance of the roof material and the basic growth requirements of the green plants, according to the change trend curve, a dehumidification strategy for the corresponding time node is generated, which is used to adjust the soil humidity at the corresponding moment, so that it can simultaneously meet the premise of ensuring that the plants meet the growth requirements and reduce the penetration progress of the roof waterproof material; if the first humidity of the current block soil is less than the basic growth requirements of the corresponding green plants, the net value of rainwater content at each moment in the future preset time period is obtained, and the second change trend curve of the first humidity of the block soil at each moment in the future preset time period is predicted according to the net value of rainwater content without human interference; according to the second change trend curve, based on the optimal humidity range of the waterproof performance of the roof material and the basic growth requirements of the green plants, a humidification strategy for the corresponding time node is generated. Since the first humidity of the current block soil is less than the basic growth requirements of the corresponding green plants, the block soil will not infiltrate water by default. Therefore, the block soil will not form a watershed storage at this time, and the drainage efficiency of the drainage device is 1 by default; The beneficial effects of the above technical scheme are: through the above technical scheme, combined with soil moisture, roof material waterproof performance, drainage efficiency of drainage device and predicted weather data, the watering strategy of the roof garden is jointly decided to ensure that the penetration progress of the roof waterproof material is reduced while the plants meet their growth needs, which is beneficial to improving the practicality of sponge city roof gardens and providing reliable basic functional support for the popularization of sponge cities.

[0028] In one embodiment, a method for managing plants in a roof garden for a sponge city further includes: A target area is set at each fork in the building to which the roof garden belongs; wherein the target area is provided with monitoring and identification equipment, and the first target area is the entrance on the first floor of the building to which the roof garden belongs; Obtaining a first real-time trajectory and a first trajectory moving time of a user from a first target area to a second target area; Based on the preset trajectory prediction model, a plurality of first predicted trajectories are generated according to the first real-time trajectory; wherein the destination of each first predicted trajectory is a roof garden; Obtain the mth real-time trajectory and the mth trajectory moving time of the user from the mth target area to the m+1th target area; wherein m is a positive integer greater than 1; Determine whether the m-th real-time trajectory coincides with the m-1-th predicted trajectory. If not, determine that the probability of the user going to the roof garden is 0. If they coincide, obtain the m-1-th overall trajectory probability corresponding to the m-1-th predicted trajectory; where the m-1-th probability overall trajectory is the probability of going to the roof garden; Based on the preset trajectory prediction model, multiple m-th predicted trajectories are generated according to the m-1th real-time trajectory and the mth real-time trajectory; wherein the destination of each m-th predicted trajectory is the roof garden; Obtain the independent probabilities of all real-time trajectories, the overall trajectory probability of the predicted trajectories corresponding to all real-time trajectories, and the moving time of each trajectory, and calculate the probability that the current user goes to the roof garden.

If the probability of the current user going to the roof garden is greater than a preset threshold, a user viewing signal is sent to the management device to control the management device to stop the humidification operation or dehumidification operation; The working principle and beneficial effects of the above technical solution are as follows: With the emergence of the concept of sponge city, roof gardens, as one of the applications, can not only increase the area of ​​urban green space and reduce the urban heat island effect, but also beautify the city, purify the air, and effectively improve people's living environment and quality of life. However, in actual applications, most community roofs are mostly used by owners, mainly for drying clothes and drying grains, etc., making it difficult for roof gardens to be actually applied on community roofs. For this reason, based on actual conditions, the present invention finds that schools are very suitable places for applying roof gardens. The reasons include: First, in order to prevent students from causing casualties on the roofs, the school roofs are usually not opened. First, the school rooftop is not open for a long time, which leads to the long-term exposure to the sun and rain, seriously affecting the service life of the roof material. In addition, when promoting the school, the school rooftop taken from aerial photography will affect the school image because it is too dilapidated. Therefore, the school rooftop is a more suitable place to promote the roof garden. At the same time, laying a roof garden on the school rooftop is also conducive to building a beautiful campus and increasing the area of ​​urban green space. When the roof garden begins to be built and the facilities such as safety fences are laid, it can also provide a beautiful viewing area for students, teachers and parents, and provide a place for teachers and students on campus to relax, reducing the probability of student depression. In order to improve the utilization rate of the roof garden and prevent the management equipment from suddenly increasing or decreasing humidity when students are watching, this scheme proposes a monitoring scheme to predict whether students will go to the roof garden based on the action trajectory and trajectory behavior score, and control the management equipment accordingly according to the prediction results in advance; it is worth mentioning that this scheme can also be used to determine whether there are still students in the roof garden, and then determine whether the students' presence is reasonable according to the current time stage, and issue corresponding alarms according to the judgment results; First, this scheme needs to set up a target area at each fork in the building to which the roof garden belongs in advance; wherein, the target area is provided with monitoring and identification equipment, and the first target area is the entrance of the first floor of the building to which the roof garden belongs. This target area is mainly used for facial recognition of students, so as to facilitate the positioning and tracking of their behavior trajectories. It is worth noting that since most of the existing teaching buildings are stairs, the target area is preferably set at the fork of the stairs, which can be combined with the monitoring equipment in the campus; Then, the first real-time trajectory and the first trajectory moving time of the user from the first target area to the second target area are obtained; the first real-time trajectory is a straight line between two points, which is beneficial to saving equipment costs compared to real-time monitoring, and the first trajectory moving time is used to determine whether the student stops during the movement; Based on the preset trajectory prediction model, a plurality of first predicted trajectories are generated according to the first real-time trajectory; wherein the destination of each first predicted trajectory is the roof garden, and the training process of the preset trajectory prediction model is preferably to collect training samples, including the action trajectories of all students going to the roof garden within a preset time period, train the initial model according to the training samples, and generate the trajectory prediction model after the training conditions are met; Further, obtaining a second real-time trajectory of the user moving from the second target area to the third target area and the second trajectory moving time; Determine whether the second real-time trajectory overlaps with the first predicted trajectory. If not, determine that the probability of the user going to the roof garden is 0. If they overlap, obtain the first probability corresponding to the first predicted trajectory; wherein the first probability is the probability of going to the roof garden; overlap refers to whether the second real-time trajectory overlaps with the first segment of the action route of the first predicted trajectory, that is, determine whether the start and end points of the second real-time trajectory overlap with the start point of the first predicted trajectory and the end point of the first segment of the action route; If there are multiple overlapping first prediction trajectories, the first probability corresponding to the first prediction trajectory is the average of the first probabilities of the multiple prediction trajectories; Based on the preset trajectory prediction model, a plurality of second predicted trajectories are generated according to the first real-time trajectory and the second real-time trajectory; wherein the destination of each second predicted trajectory is a roof garden; Repeat the above scheme to obtain the mth real-time trajectory and the mth trajectory moving time of the user from the mth target area to the m+1th target area; where m is a positive integer greater than 1; Determine whether the m-th real-time trajectory overlaps with the m-1-th predicted trajectory. If not, determine that the probability of the user going to the roof garden is 0. If they overlap, obtain the m-1-th overall trajectory probability corresponding to the m-1-th predicted trajectory; wherein the m-1-th probability overall trajectory is the probability of going to the roof garden; wherein, when the user goes from area A to area B and then returns from area B to area A, the probability of the user going to the roof garden is determined to be 0. At the same time, when the user stays in any intermediate area for more than a preset threshold, the probability of the user going to the roof garden is determined to be 0 until the user reappears in the target area and is recalculated; the intermediate area refers to an unmonitored area between any two target areas, such as a classroom; Based on the preset trajectory prediction model, multiple m-th predicted trajectories are generated according to the m-1th real-time trajectory and the mth real-time trajectory; wherein the destination of each m-th predicted trajectory is the roof garden; The acquisition is terminated until it is determined that the probability of the user going to the roof garden is 0 or the probability of the user going to the roof garden is greater than a preset threshold; All the acquired data is used to calculate the probability of the user going to the roof garden, including: Obtain the independent probabilities of all real-time trajectories, the overall trajectory probability of the predicted trajectories corresponding to all real-time trajectories, and the moving time of each trajectory, and calculate the probability that the current user goes to the roof garden; The independent probability of all real-time trajectories refers to the independent probability that the students going to the roof garden choose this trajectory to move forward. The calculation of the independent probability of each real-time trajectory is preferably calculated based on the training samples in the preset trajectory prediction model; the real-time trajectory refers to the trajectory from one target area to the next target area; The overall trajectory probability of the predicted trajectory corresponding to all real-time trajectories refers to the overall probability of the students heading to the roof garden moving forward along the overall trajectory. The calculation of the overall probability of each predicted trajectory is preferably calculated based on the training samples in the preset trajectory prediction model; the predicted trajectory refers to the trajectory from a target area to the roof garden; Since the parameter source in the above probability calculation formula ends when it is determined that the probability of the user going to the roof garden is 0 or the probability of the user going to the roof garden is greater than a preset threshold, the value of M changes in real time; Since a teaching building usually has a gate and everyone enters through this gate, there is a necessary passage. Indicates the probability of the must-go channel, which is usually a fixed value and is used to correct the probability of the current user going to the roof garden, which is related to the preset threshold; As the user moves, the value of M changes in real time. The value is updated in real time; The probability of the current user going to the roof garden is obtained in real time. If the probability of the current user going to the roof garden is greater than a preset threshold, a user viewing signal is sent to the management device to control the management device to stop the humidification operation or the dehumidification operation.
