Description

Technical Field

[0001] The present application relates to the field of green energy-saving building technology, and in particular to a green plant maintenance method, device, storage medium and electronic equipment for a green plant wall. Background Art

[0002] Green wall is a form of vertical greening that uses green plants, that is, green plants to cover the wall. It is also called plant wall, vertical garden or ecological green plant. This kind of wall achieves the effects of beautifying space, purifying air and reducing noise by planting plants on the wall or other vertical surfaces of the building. At present, green walls in building spaces are becoming more and more popular and popular as an important part of green energy-saving buildings. Among them, green energy-saving buildings refer to buildings that focus on environmental optimization and protection and resource conservation during their life cycle. They are a form of architecture that conforms to the concept of sustainable development. In addition, good maintenance and management are the key to ensuring the beauty and long-lasting functions of green walls, and it is also the key to maximize the role of green walls. The more important part of maintenance and management is usually pest monitoring. With the popularity of green walls, how to effectively maintain the green plants in green walls is an urgent problem to be solved.

[0003] At present, the usual method for maintaining green plants in green plant walls is: regularly inspect the green plants in the green plant walls for pests by specially assigned maintenance personnel, and carry out pest control once pests are found, so as to ensure the high health and growth trend of the green plants. However, under this method, maintenance personnel mainly perform regular maintenance based on experience, which has the hidden danger of untimely discovery of pests, making the pest maintenance work of green plants relatively lagging, resulting in poor refinement of the maintenance management of green plants in the green plant walls. Summary of the invention

[0004] In order to improve the refinement of the maintenance and management of green plants in a green wall, the present application provides a green plant maintenance method, device, storage medium and electronic device for a green wall.

[0005] In a first aspect of the present application, a green plant maintenance method for a green plant wall is provided, which specifically includes: Obtaining a first light intensity in an area where a green plant wall is located and at least one set of first soil nutrient contents in a single green plant area in the green plant wall; When the current temperature and the current humidity in the area where the green plant wall is located are both within the corresponding green plant suitable range, if the first light intensity is lower than a preset light intensity threshold, determining the soil nutrient consumption rate of the corresponding green plant area according to each of the first soil nutrient contents; If the soil nutrient consumption rate is greater than a preset rate threshold, the corresponding green plant area is determined as a key green plant area, a target green plant area is selected from other green plant areas in the green plant wall, and a first wind direction from each of the target green plant areas to the key green plant area is determined, and the target green plant area is a green plant area where the carbon dioxide concentration is higher than a preset first concentration threshold; Increasing the light intensity of the key green plant area to a second light intensity, and performing ventilation according to each of the first wind directions, wherein the second light intensity is greater than the light intensity threshold; Obtain at least one group of second soil nutrient contents of the key green plant area under the second light intensity during ventilation, and determine whether there is an insect pest risk in the key green plant area based on each of the second soil nutrient contents. If so, send an insect pest reminder to the maintenance personnel's terminal.

[0006] By adopting the above technical solution, if the first light intensity is lower than the preset light intensity threshold, it means that the light in the area where the green plant wall is located is insufficient, the respiration of the green plants is stronger than photosynthesis, and carbon dioxide is mainly produced. Then, when the soil nutrient consumption rate is too fast, it means that there may be a risk of pests. Then, the first wind direction from each target green plant area to the key green plant area is determined, and ventilation treatment is performed according to the first wind direction. If there is pest, carbon dioxide is blown to the key green plant area, which can inhibit the pest activity and prevent the pest from further expanding, while improving the growth environment of the green plants in the target green plant area. At the same time, the light intensity of the key green plant area is increased to the second light intensity, temporarily weakening the respiration of the green plants in the key green plant area, and combined with at least one group of second soil nutrient content in the key green plant area under the second light intensity, the possibility of excessive respiration of the green plants leading to excessive soil nutrient consumption is checked, and then accurately determine whether there is a risk of pests. If there is, a pest reminder is sent to the terminal of the maintenance personnel, so as to timely and thoughtfully manage the pest problem of the green plants and improve the refinement of the maintenance management of the green plants.

[0007] Optionally, determining whether there is an insect pest risk in the key green plant area according to the nutrient content of each of the second soils specifically includes: Determine a first nutrient content change curve of the soil nutrient content of the key green plant area over time according to each of the first soil nutrient contents, and determine a second nutrient content change curve of the soil nutrient content of the key green plant area over time according to each of the second soil nutrient contents; Fitting the first nutrient content change curve with the second nutrient content change curve to obtain a fitting rate; The fitting rate is compared with a preset fitting rate threshold, and if the fitting rate exceeds the fitting rate threshold, it is determined that there is an insect pest risk in the key green plant area; If the fitting rate does not exceed the fitting rate threshold, it is determined that there is no insect pest risk in the key green plant area.

[0008] By adopting the above technical solution, if the fitting rate exceeds the preset fitting rate threshold, it means that the first nutrient content change curve and the second nutrient content change curve are relatively similar, and the nutrient consumption rate is still relatively fast, indicating that the effect of reducing respiration is not significant, then it is determined that there is an insect pest risk in the key green plant area; if the fitting rate does not exceed the preset fitting rate threshold, it means that reducing respiration has taken effect and the nutrient consumption rate has changed, then it is determined that there is no insect pest risk in the key green plant area, thereby more accurately determining whether there is an insect pest risk.

[0009] Optionally, the method further includes: If the first light intensity is not lower than a preset light intensity threshold, the first occurrence times of the historical distribution areas of the personnel in the space where the green wall is located are counted, and the historical distribution area with the first number is selected from each of the historical distribution areas in descending order of the first occurrence times to determine as the easy distribution area; Counting the second occurrence number of the historical period in which people are distributed in each of the easy distribution areas, and selecting the historical period with the second number from each of the historical periods in descending order of the second occurrence number to determine the easy distribution period of the corresponding easy distribution area; Calculate a first weight of each of the easy distribution areas and a second weight of the corresponding easy distribution period, wherein the first weight is a ratio of a first occurrence number of each of the easy distribution areas to a sum of first occurrence numbers of all the easy distribution areas, and the second weight is a ratio of a second occurrence number of a single easy distribution period corresponding to the easy distribution area to a sum of second occurrence numbers of all corresponding easy distribution periods; Based on the first weight and the corresponding second weight, determining a first oxygen blowing area currently requiring oxygen blowing from each of the easy distribution areas; Determine the second wind direction from each oxygen-rich green plant area in the green plant wall to the first oxygen blowing area, and perform ventilation according to each of the second wind directions. The oxygen-rich green plant area is a green plant area where the oxygen concentration exceeds a preset second concentration threshold.

[0010] By adopting the above technical solution, the greater the first number of occurrences, the more likely people are to appear in the corresponding historical distribution area, and thus the easy distribution area is determined; the greater the second number of occurrences, the more likely people are distributed in the easy distribution area in the corresponding historical period, and thus the easy distribution period is determined. Then, combined with the first weight of the easy distribution area and the second weight of the corresponding easy distribution period, the first oxygen blowing area that currently needs oxygen blowing is analyzed and determined. Finally, ventilation treatment is performed according to the second wind direction from each oxygen-rich green plant area to the first oxygen blowing area, so as to transport the oxygen generated by the green plants to the area where people may be distributed, and optimize the air conditions in advance.

[0011] Optionally, the determining, based on the first weight and the corresponding second weight, a first oxygen blowing area currently requiring oxygen blowing from each of the easy distribution areas specifically includes: Determine the easy distribution period after the current time of each of the easy distribution areas as the first key period, and calculate the first weight product of the first weight of each of the easy distribution areas and the second weight of each corresponding first key period; Summing the first weight products to obtain the sum of the first weight products of the corresponding easy-distribution areas; The maximum sum of the first weighted products is selected from the sums of the first weighted products, and the easy distribution area corresponding to the maximum sum of the first weighted products is determined as the first oxygen blowing area currently requiring oxygen blowing.

[0012] By adopting the above technical solution, the larger the sum of the first weight products, the greater the possibility of personnel being distributed in the corresponding easy-to-distribute area after the current time, and the more oxygen needs to be transported to optimize the air conditions in the area with a high probability of personnel distribution. Finally, the easy-to-distribute area corresponding to the maximum sum of the first weight products is determined as the first oxygen blowing area that currently needs oxygen blowing, and the oxygen in the oxygen-rich green plant area is blown to this first oxygen blowing area, thereby optimizing the air conditions in the area with a high probability of personnel distribution in advance.

[0013] Optionally, performing ventilation processing according to each of the second wind directions specifically includes: Obtaining a first humidity in the first oxygen blowing area and a second humidity in each oxygen-enriched green plant area; If the first humidity is lower than a preset humidity threshold, a ventilation order of a corresponding second wind direction is determined according to the second humidity, and the higher the second humidity, the earlier the corresponding ventilation order; According to the ventilation sequence, ventilation is performed according to the corresponding second wind direction.

[0014] By adopting the above technical solution, if the first humidity is lower than the preset humidity threshold, it means that the first oxygen blowing area is relatively dry. Once there are people, they will feel uncomfortable. Then, according to the second humidity of each oxygen-rich green plant area, the ventilation order of the second wind direction from the corresponding oxygen-rich green plant area to the first oxygen blowing area is determined. The higher the second humidity, the easier it is to breed pests. The earlier the corresponding ventilation order, the higher the priority of ventilation treatment. This can not only optimize the air quality of the first oxygen blowing area, but also improve the dryness problem and reduce the risk of pest breeding in the oxygen-rich green plant area.

[0015] Optionally, the method further includes: From the easy distribution time periods after the current time of each of the easy distribution areas, select the easy distribution time period closest to the current time and determine it as the second key time period; Calculate a second weight product of the first weight of each of the easy distribution areas and the second weight of the corresponding second key time period; Selecting a maximum second weighted product from each of the second weighted products, and determining an easy-distribution region corresponding to the maximum second weighted product as a second oxygen blowing region; When the current time is within the second key time period corresponding to the maximum second weight product, the third wind directions from each oxygen-rich green plant area in the green plant wall to the second oxygen blowing area are determined, and ventilation is performed according to each third wind direction.

[0016] By adopting the above technical solution, the larger the second weight product is, the more likely it is that people will be distributed in the corresponding easy-to-distribute area. Then, the maximum second weight product is selected from each second weight product, and the easy-to-distribute area corresponding to the maximum second weight score is determined as the second oxygen blowing area, that is, the area where people are most likely to be distributed and oxygen needs to be transported in the most recent time period after the current time. Furthermore, when the current time comes to the second key time period corresponding to the maximum second weight product, the ventilation treatment according to the second wind direction is adjusted to the ventilation treatment according to each third wind direction, so as to more reasonably transport oxygen to the area with a greater possibility of distribution of people and improve the air condition.

[0017] Optionally, the method further includes: Counting the remaining distance for the maintenance personnel to reach the key green plant area; If the remaining distance is less than the preset distance threshold, determining the polyoxygen green plant areas in the green plant wall where the oxygen concentration is higher than the preset third concentration threshold, and determining the third humidity of each polyoxygen green plant area; Determine a fourth wind direction from the key green plant area to each of the polyoxygen green plant areas, and determine a ventilation order corresponding to the fourth wind direction according to the third humidity, wherein the higher the third humidity, the earlier the corresponding ventilation order; According to the ventilation sequence, ventilation is performed according to the corresponding fourth wind direction.

[0018] By adopting the above technical solution, if the remaining distance is less than the distance threshold, it means that the maintenance personnel are close to the key green plant area and may feel uncomfortable due to the large amount of carbon dioxide blown to the key green plant area. The carbon dioxide needs to be blown away from the key green plant area. Then, according to the third humidity, the ventilation order of the corresponding fourth wind direction is determined. The higher the third humidity, the greater the risk of pests breeding in the corresponding polyoxygen green plant area, and the more it needs to prioritize the delivery of carbon dioxide to reduce the risk of pests.

[0019] In a second aspect of the present application, a green plant maintenance device for a green plant wall is provided, specifically comprising: An information acquisition module, used to acquire a first light intensity in an area where the green plant wall is located and at least one group of first soil nutrient contents in a single green plant area in the green plant wall; a speed determination module, for determining the soil nutrient consumption speed of the corresponding green plant area according to each of the first soil nutrient contents when the current temperature and the current humidity of the area where the green plant wall is located are both within the corresponding green plant suitable range and if the first light intensity is lower than a preset light intensity threshold; a wind direction determination module, for determining the corresponding green plant area as a key green plant area if the soil nutrient consumption rate is greater than a preset rate threshold, selecting a target green plant area from other green plant areas in the green plant wall, and determining a first wind direction from each of the target green plant areas to the key green plant area, wherein the target green plant area is a green plant area where the carbon dioxide concentration is higher than a preset first concentration threshold; a ventilation processing module, used to increase the light intensity of the key green plant area to a second light intensity and perform ventilation processing according to each of the first wind directions, wherein the second light intensity is greater than the light intensity threshold; The pest reminder module is used to obtain at least one group of second soil nutrient contents of the key green plant area under the second light intensity during ventilation, and determine whether there is a pest risk in the key green plant area based on each of the second soil nutrient contents. If so, a pest reminder is sent to the maintenance personnel's terminal.

[0020] By adopting the above technical solution, the information acquisition module acquires the first light intensity and the first soil nutrient content, the speed determination module determines the soil nutrient consumption rate according to each first soil nutrient content, and then the wind direction determination module determines the first wind direction from each target green plant area to the key green plant area, and then the processing module performs ventilation according to each first wind direction. Finally, if there is a pest risk in the key green plant area, a pest reminder is sent to the maintenance personnel's terminal.

[0021] In a third aspect of the present application, a computer-readable storage medium is provided, in which a computer program is stored. When the computer program is loaded and executed by a processor, the method steps described in any one of the first aspects are performed.

[0022] In a fourth aspect of the present application, an electronic device is provided, specifically comprising: A processor, a memory, and a computer program stored in the memory and capable of running on the processor, wherein the processor is used to load and execute the computer program stored in the memory so that the electronic device performs the method as described in any one of the first aspects.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: ventilation treatment is performed according to the first wind direction, and if pests exist, carbon dioxide is blown to the key green plant area, which can inhibit pest activities and prevent further expansion of pests, while improving the growth environment of green plants in the target green plant area. At the same time, the light intensity in the key green plant area is increased to the second light intensity, temporarily weakening the respiration of green plants in the key green plant area, and combined with at least one group of second soil nutrient content in the key green plant area under the second light intensity, the possibility of excessive respiration of green plants leading to excessive consumption of soil nutrients is checked, and then accurately determine whether there is a pest risk. If so, a pest reminder is sent to the maintenance personnel's terminal, so as to timely and thoughtfully manage the pest problems of green plants and improve the refinement of green plant maintenance management.

[0029] See also Figure 1 The present application embodiment discloses a flow chart of a green plant maintenance method for a green plant wall, which can be implemented by a computer program or run on a green plant maintenance device for a green plant wall based on a von Neumann system. The computer program can be integrated into an application or run as an independent tool application, specifically including: S101: Obtain a first light intensity in an area where a green plant wall is located and at least one set of first soil nutrient contents in a single green plant area in the green plant wall.

[0030] Specifically, the overall light intensity of the area where the green plant wall is located is obtained through a light intensity sensor preset in the area where the green plant wall is located. The higher the light intensity, the stronger the photosynthesis of the green plants in the green plant wall, and the more oxygen produced by photosynthesis. The first light intensity can be the average light intensity within the preset time, or it can be the real-time light intensity at the current time. The green plant wall includes at least one green plant area, and each green plant area includes one or more green plants. A soil nutrient sensor is preset in the soil part corresponding to each green plant area, which can measure the soil nutrient content of the corresponding green plant area. In an embodiment of the present application, at least one group of first soil nutrient contents of a single green plant area within a preset time is obtained through a soil nutrient sensor, and each group of first soil nutrient contents is the nitrogen content in the soil at the corresponding moment. In other embodiments, each group of first soil nutrient contents is the content of nitrogen, phosphorus, potassium and other elements in the soil at the corresponding moment. Among them, the preset time can be within 1 hour before the current time.

[0031] It should be noted that the executor of the green plant maintenance method for a green plant wall disclosed in an embodiment of the present application may be a server, and the server is directly or indirectly connected to light sensors, soil nutrient sensors, etc. through a wireless network, wherein the server may specifically be an independent physical server, or a server cluster or distributed system composed of multiple physical servers.

[0032] S102: When the current temperature and the current humidity in the area where the green plant wall is located are both within the corresponding suitable range for green plants, if the first light intensity is lower than a preset light intensity threshold, the soil nutrient consumption rate of the corresponding green plant area is determined according to the first soil nutrient content.

[0033] Specifically, after the first light intensity and the first soil nutrient content are determined, the current temperature and humidity are obtained through the preset temperature sensor and humidity sensor in the area where the green plant wall is located. When the current temperature and humidity are both in the corresponding suitable range for green plants, it means that the temperature and humidity at the current time are more suitable for the green plants in the green plant wall. Further, the first light intensity is compared with the preset light intensity threshold. If the first light intensity is lower than the light intensity threshold, it means that the light intensity in the area where the green plant wall is located is low during the preset time, and the respiration of the green plant is stronger than the photosynthesis, mainly producing carbon dioxide, and the nutrient consumption rate in the soil may be accelerated. This is because when the light is insufficient, the photosynthesis of the green plant is weakened, and the energy generated is reduced, which directly affects the absorption speed and intensity of the green plant to the nutrients. In this case, in order to maintain basic life activities, the green plant may accelerate the consumption of existing nutrients in the soil to make up for the energy loss caused by insufficient light. Then the difference between the first soil nutrient content at the latest time and the first soil nutrient content at the earliest time is divided by the total time to obtain the corresponding soil nutrient consumption rate.

[0034] S103: If the soil nutrient consumption rate is greater than a preset rate threshold, the corresponding green plant area is determined as a key green plant area, a target green plant area is selected from other green plant areas in the green plant wall, and the first wind direction from each target green plant area to the key green plant area is determined. The target green plant area is a green plant area where the carbon dioxide concentration is higher than the preset first concentration threshold.

[0035] Specifically, if the soil nutrient consumption rate is greater than the preset rate threshold, the corresponding green plant area is determined as a key green plant area, indicating that the key green plant area consumes soil nutrients at a faster rate. This may be due to excessive respiration of the green plants, which consumes nutrients too quickly, or the presence of insect pests, which causes the soil nutrient consumption rate to be too fast. Furthermore, the carbon dioxide concentration of the remaining green plant areas in the green plant wall is obtained through a preset infrared carbon dioxide sensor, and the green plant area with a carbon dioxide concentration higher than the preset first concentration threshold is determined as the target green plant area. The carbon dioxide concentration in the target green plant area is too high, which is not conducive to the healthy growth of green plants in the target green plant area, and will also affect the indoor air quality, requiring ventilation. Then, according to the location information of the target green plant area and the location information of the key green plant area determined by the GPS module, the first wind direction from each target green plant area to the key green plant area is determined. It should be noted that ventilation according to the first wind direction can improve the growth environment of green plants in the target green plant area. At the same time, when the soil nutrient consumption rate is too fast due to excessive respiration, blowing carbon dioxide to the key green plant area can inhibit respiration to a certain extent, avoiding adverse effects on the green plants themselves and human activities in the key green plant area; when the soil nutrient consumption rate is too fast due to the presence of pests, blowing carbon dioxide to the key green plant area can inhibit the pest activities and avoid further expansion of the pests.

[0036] S104: Raise the light intensity of the key green plant area to a second light intensity, and perform ventilation according to each first wind direction, wherein the second light intensity is greater than a light intensity threshold.

[0037] Specifically, the key green plant area is illuminated by a preset artificial light source, and the light intensity of the key green plant area is increased to a second light intensity, which is greater than the light intensity threshold, so that the photosynthesis of the green plants in the key green plant area is enhanced and the respiration is temporarily weakened. If the key green plant area consumes nutrients faster because the respiration of the green plants is too strong, then the nutrient consumption rate under the second light intensity will change to a certain extent. Among them, the artificial light source can be an LED lamp, and in other embodiments, it can also be a metal halide lamp.

[0038] Furthermore, the ventilation device preset in the area where the green plant wall is located blows the carbon dioxide in the corresponding target green plant area to the key green plant area in sequence according to the first wind direction through the ventilation device, and the ventilation duration is the preset duration, and the ventilation device can be a ventilation fan. In addition, the higher the carbon dioxide concentration in the target green plant area, the earlier the ventilation treatment is performed according to the corresponding first wind direction, so that the carbon dioxide concentration in the target green plant area that most needs to improve the growth environment is reduced first.

[0039] S105: Obtain at least one set of second soil nutrient content of the key green plant area under the second light intensity during ventilation, and determine whether there is a pest risk in the key green plant area based on each second soil nutrient content. If so, send a pest reminder to the maintenance personnel's terminal.

[0040] Specifically, during the ventilation treatment of the key green plant area according to the first wind direction, at least one set of second soil nutrient content is obtained in real time through the soil nutrient sensor, and then according to each second soil nutrient content, a second nutrient content change curve of the key green plant area's soil nutrient content over time is drawn through a preset MATLAB tool. Similarly, according to each first soil nutrient content, a first nutrient content change curve of the key green plant area's soil nutrient content over time is drawn through a MATLAB tool.

[0041] Furthermore, the first nutrient content change curve and the second nutrient content change curve are fitted by the MATLAB tool to obtain the fitting rate. If the fitting rate exceeds the preset fitting rate threshold, it means that the first nutrient content change curve and the second nutrient content change curve are relatively similar, and the nutrient consumption rate is still fast, indicating that the effect of reducing respiration is not significant, indicating that the nutrient consumption is too fast and is not caused by strong respiration, then it is determined that there is a risk of pests in key green plant areas; if the fitting rate does not exceed the preset fitting rate threshold, it means that reducing respiration has an effect and the nutrient consumption rate has changed, then it is determined that there is no risk of pests in key green plant areas. Finally, if it is determined that there is a risk of pests, a pest reminder is sent to the terminal of the maintenance personnel to remind the maintenance personnel to check and eliminate pests in time. Among them, the terminal can be a smart phone or a personal computer.

[0042] In other embodiments, if the first light intensity of the area where the green wall is located is not lower than the light intensity threshold, it means that the light intensity of the area is sufficient, the photosynthesis of the green plants is strong, and oxygen is mainly produced. Then, a feasible and reliable way to determine the historical distribution area of ​​the personnel in the space where the green wall is located is: filter out the historical distribution area of ​​the personnel from the surveillance video of the preset camera in the space, count the first occurrence times of each historical distribution area, the larger the first occurrence times, the easier it is for the personnel to appear in the corresponding historical distribution area, and select the first number of historical distribution areas from each historical distribution area in the order of the first occurrence times from large to small and determine it as the easy distribution area, that is, the area where the personnel are easy to be located in the space. Further, count the second occurrence times of the historical period in which the personnel are distributed in each easy distribution area, the larger the second occurrence times, the easier it is for the personnel to be distributed in the easy distribution area in the corresponding historical period, and then select the second number of historical period from each historical period in the order of the second occurrence times from large to small to determine it as the easy distribution period of the corresponding easy distribution area, that is, the period in which the personnel are more likely to be distributed in the easy distribution area.

[0043] Further, the first weight of each easy-to-distribute area and the second weight of the corresponding easy-to-distribute time period are calculated, the first weight being the ratio of the first occurrence number of each easy-to-distribute area to the sum of the first occurrence numbers of all easy-to-distribute areas, and the second weight being the ratio of the second occurrence number of a single easy-to-distribute time period corresponding to the easy-to-distribute area to the sum of the second occurrence numbers of all corresponding easy-to-distribute time periods. Further, the easy-to-distribute time periods after the current time are screened out from the various easy-to-distribute time periods corresponding to the single easy-to-distribute area, and are all determined as the first key time periods, that is, time periods where people may be distributed after the current time. Further, the first weight product of each easy-to-distribute area and the second weight of each corresponding first key time period is calculated, and then the first weight products corresponding to the single easy-to-distribute area are summed to obtain the corresponding sum of the first weight products, wherein the larger the sum of the first weight products is, the greater the possibility of people being distributed in the corresponding easy-to-distribute area after the current time, and the more oxygen needs to be transported to optimize the air conditions in the area with a high probability of people being distributed.

[0044] Furthermore, the maximum first weight product sum is selected from the sums of the first weight products, and the easily distributed area corresponding to the maximum first weight product sum is determined as the first oxygen blowing area that currently requires oxygen blowing. Then, the oxygen concentration of each green plant area in the green plant wall is obtained through a preset electrochemical oxygen sensor, and the green plant area whose oxygen concentration exceeds the preset second concentration threshold is determined as the oxygen-rich green plant area. Finally, the second wind direction from each oxygen-rich green plant area to the first oxygen blowing area is determined, and ventilation treatment is performed according to each second wind direction. A feasible implementation method is: through a preset humidity sensor, the first humidity of the first oxygen blowing area and the second humidity of each oxygen-rich green plant area are obtained. If the first humidity is lower than the preset humidity threshold, it means that the first oxygen blowing area is relatively dry. Once people are present, an uncomfortable experience will occur. Then, according to the second humidity of each oxygen-rich green plant area, the ventilation order of the second wind direction from the corresponding oxygen-rich green plant area to the first oxygen blowing area is determined. The higher the second humidity, the easier it is to breed pests. The earlier the corresponding ventilation order, the higher the priority of ventilation treatment. Not only can the air quality of the first oxygen blowing area be optimized, but also the dryness problem can be improved, and the risk of pest breeding in the oxygen-rich green plant area can be reduced.

[0045] In another embodiment, during ventilation processing according to each second wind direction, the easy distribution time period closest to the current time is selected from the easy distribution time period after the current time of each easy distribution area, and is determined as the second key time period corresponding to the single easy distribution area, wherein the time difference between the start time of the second key time period and the current time is the smallest. Further, the second weight product of the first weight of each easy distribution area and the second weight of the corresponding second key time period is calculated, and the larger the second weight product is, the more likely it is that the corresponding easy distribution area will be distributed with personnel. Then, the maximum second weight product is selected from each second weight product, and the easy distribution area corresponding to the maximum second weight score is determined as the second oxygen blowing area, that is, the area where personnel are most likely to be distributed in the closest time period after the current time and oxygen needs to be transported.

[0046] As time goes by, when the current time reaches the second key period corresponding to the maximum second weight product, the third wind direction from each oxygen-rich green plant area in the green plant wall to the second oxygen blowing area is determined, and ventilation treatment is adjusted from the second wind direction to each third wind direction. When the current time exceeds the second key period corresponding to the maximum second weight product, the above steps of determining the first oxygen blowing area are repeated to redetermine the area that needs oxygen blowing again at the current time.

[0047] See also Figure 2The present application embodiment discloses a flow chart of another method for maintaining green plants on a green wall, which can be implemented by a computer program or run on a green plant maintenance device for a green wall based on a von Neumann system. The computer program can be integrated into an application or run as an independent tool application, specifically including: S201: Obtain a first light intensity in the area where the green wall is located and at least one set of first soil nutrient contents in a single green plant area in the green wall.

[0048] S202: When the current temperature and the current humidity in the area where the green plant wall is located are both within the corresponding suitable range for green plants, if the first light intensity is lower than a preset light intensity threshold, the soil nutrient consumption rate of the corresponding green plant area is determined according to the first soil nutrient content.

[0049] S203: If the soil nutrient consumption rate is greater than a preset rate threshold, the corresponding green plant area is determined as a key green plant area, a target green plant area is selected from other green plant areas in the green plant wall, and the first wind direction from each target green plant area to the key green plant area is determined. The target green plant area is a green plant area where the carbon dioxide concentration is higher than the preset first concentration threshold.

[0050] S204: Raise the light intensity of the key green plant area to a second light intensity, and perform ventilation according to each first wind direction, wherein the second light intensity is greater than a light intensity threshold.

[0051] S205: Obtain at least one set of second soil nutrient content of the key green plant area under the second light intensity during ventilation, and determine whether there is an insect pest risk in the key green plant area based on each second soil nutrient content. If so, send an insect pest reminder to the maintenance personnel's terminal.

[0052] For details, please refer to steps S101-S105, which will not be described in detail here.

[0053] S206: Count the remaining distance for the maintenance personnel to reach the key green plant area.

[0054] S207: If the remaining distance is less than the preset distance threshold, determine the oxygen-rich green plant areas in the green plant wall where the oxygen concentration is higher than the preset third concentration threshold, and determine the third humidity of each oxygen-rich green plant area.

[0055] S208: Determine the fourth wind direction from the key green plant area to each oxygen-rich green plant area, and determine the ventilation order corresponding to the fourth wind direction according to the third humidity. The higher the third humidity, the earlier the corresponding ventilation order.

[0056] S209: Perform ventilation processing according to the ventilation sequence and the corresponding fourth wind direction.

[0057] Specifically, after sending the pest reminder to the maintenance personnel, the remaining distance for the maintenance personnel to reach this key green plant area for pest control is determined based on the location information shared in real time by the maintenance personnel's terminal. This remaining distance is compared with the preset distance threshold. If the remaining distance is less than the distance threshold, it means that the maintenance personnel are close to the key green plant area and may feel uncomfortable due to the large amount of carbon dioxide blown to the key green plant area. The carbon dioxide needs to be blown out of the key green plant area. Then the oxygen concentration of each green plant area in the green plant wall is counted, and the green plant area with an oxygen concentration higher than the preset third concentration threshold is determined as a polyoxygen green plant area, that is, a green plant area with a risk of pest breeding when the light is insufficient, and the third concentration threshold is lower than the second concentration threshold. Then the third humidity of each polyoxygen green plant area is obtained, and further, the fourth wind direction from the key green plant area to each polyoxygen green plant area is determined, and the ventilation order of the corresponding fourth wind direction is determined according to the third humidity. The higher the third humidity, the greater the risk of pest breeding in the corresponding polyoxygen green plant area, the more it is necessary to give priority to the delivery of carbon dioxide to reduce the risk of pest occurrence, and the ventilation order of the corresponding fourth wind direction is closer. Finally, according to the ventilation sequence of each fourth wind direction, ventilation processing is performed according to the corresponding fourth wind direction.

[0058] The implementation principle of a green plant maintenance method for a green plant wall in an embodiment of the present application is as follows: ventilation is performed according to a first wind direction, and if pests exist, carbon dioxide is blown to key green plant areas, which can inhibit pest activities and prevent further expansion of pests, while improving the growth environment of green plants in the target green plant areas. At the same time, the light intensity in the key green plant area is increased to a second light intensity, temporarily weakening the respiration of green plants in the key green plant area, and combined with at least one group of second soil nutrient content in the key green plant area under the second light intensity, the possibility of excessive respiration of green plants leading to excessive consumption of soil nutrients is checked, and then accurately determine whether there is a pest risk. If so, a pest reminder is sent to the terminal of the maintenance personnel, so as to timely and thoughtfully manage the pest problems of green plants and improve the refinement of green plant maintenance management.
