[0011] By using the above technical scheme, whether the green area needs to be irrigated is judged by the soil moisture content of the detection points, and accurate irrigation of the green area can be carried out from the actual situation of the green area, so that the irrigation efficiency is high.

[0012] Optionally, in the case where the type of the green area is a slope, the green area includes an uphill green area and a downhill green area, the height of the uphill green area is higher than the irrigation equipment, and the height of the downhill green area is lower than the irrigation equipment;

[0024] By adopting the above technical solution, the irrigation strategy of the irrigation equipment is adjusted according to the different positions of the target detection point in the green area, so that the irrigation strategy is more in line with the actual situation.

[0025] Optionally, a real-time image of the green area is obtained;

[0026] The position of the vegetation with a height greater than a preset height in the real-time image is obtained;

[0027] If the vegetation position is located in the downhill green area, the relative distance between the irrigation equipment and the vegetation position is calculated;

[0028] According to the relative distance and the slope gradient, the water outlet angle and the expected water flow rate of the irrigation equipment are calculated;

[0030] By adopting the technical scheme, when the vegetation height is too high, the irrigation equipment is controlled to irrigate at the vegetation position, so that the water mist can be liquefied on the vegetation and form runoff, thereby indirectly irrigating the plants behind the vegetation.

[0038] If there is only one second irrigation equipment, the second irrigation equipment is started, so that the irrigation range of the second irrigation equipment reaches the maximum irrigation range;

[0039] If there are at least two second irrigation equipments, it is judged whether there is an overlapping area between the second irrigation equipments;

[0040] If there is no overlapping area between the maximum irrigation ranges of the second irrigation equipments, the second irrigation equipments are started, so that the irrigation range of the second irrigation equipments reaches the maximum irrigation range;

[0041] If there is an overlapping area between the maximum irrigation ranges of the second irrigation equipments, the second irrigation equipments are combined two by two to obtain a set of irrigation equipment combinations; the union set area of the maximum irrigation range of each irrigation equipment combination in the set of irrigation equipment combinations in the green area is calculated; a target irrigation equipment combination corresponding to the maximum union set area in the union set area is taken; the target irrigation equipment combination is started, so that the irrigation range of the target irrigation equipment combination reaches the maximum irrigation range.

[0042] By using the second irrigation equipment to irrigate the green area, the irrigation demand of the green area is met as much as possible.

[0043] Optionally, meteorological information of a location of the green area is acquired.

[0044] According to the meteorological information and the soil water content, a soil water content change trend of the green area is predicted.

[0045] According to the soil water content change trend and the meteorological information, the total irrigation water amount and the irrigation time are set.

[0046] By using the above technical solution, the total irrigation water amount and the irrigation time of the irrigation equipment are adjusted through the meteorological information, so that the use of the irrigation equipment is more in line with the actual demand, and the irrigation efficiency is higher.

[0070] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0071] The embodiments of the present application disclose a greenery irrigation control system. Referring to Figure 1 , the system comprises an irrigation device 11, a sensor 12, a control device 13 and a server 14.

[0072] The irrigation device 11 is used to deliver water to the greenery area. Optionally, the irrigation device 11 used in the present application is a sprinkler device, and the irrigation device 11 adopts a rotating sprinkler or a fixed sprinkler. Optionally, the water flow and the water direction of the irrigation device 11 are variable. Further, the irrigation device 11 is internally provided with a flow sensor and a water pressure sensor. Optionally, the irrigation device 11 is used to spray liquid, wherein the sprayed liquid comprises at least one of water, nutrient solution and pesticide.

[0073] The sensor 12 comprises a camera, a meteorological sensor and a soil moisture sensor. The meteorological sensor is used to measure the wind speed and the wind direction, and the soil moisture sensor is used to measure the soil water content.

[0074] The control device 13 is used to manage and monitor other devices in the greenery irrigation control system.

[0075] The server 14 is used to transmit network data to the control device 13. Optionally, the network data comprises at least one of meteorological information, rainfall information, wind speed information and wind direction information.

[0076] The embodiments of the present application disclose a greenery irrigation control method. Referring to Figure 2 , the method comprises:

[0077] Step S21: acquiring the soil water content of a detection point in the greenery area.

[0078] The greenery area refers to an area where vegetation is planted. The greenery area comprises a park green land, a square green land, a road green belt, a community green land and a city green channel, etc.

[0079] Optionally, the detection points are randomly distributed in the greenery area, or the detection points are arranged in the greenery area according to a preset rule.

[0080] The soil moisture sensor is arranged at the detection point, and the soil moisture sensor can be used to detect the soil water content. Exemplarily, after the soil moisture sensor acquires the soil water content of the detection point, the soil water content is sent to the control device.

[0081] In another aspect of the embodiment, a real-time image of the green area is acquired by the camera; a soil color of the green area is recognized from the real-time image; and the soil moisture of the detection point is determined according to the soil color. The soil color is dependent on the soil moisture, so the soil moisture can be determined by the soil color.

[0082] Step S22: Count the number of detection points with soil moisture less than the preset soil moisture.

[0083] The preset soil moisture is a constant, and the preset soil moisture is related to the type of vegetation planted in the green area. For example, when the type of vegetation is herbaceous plants, the preset soil moisture is 15%; when the type of vegetation is shrubs, the preset soil moisture is 20%.

[0084] Optionally, the preset soil moisture is also related to the ambient temperature. For example, when the ambient temperature is between 25 degrees and 30 degrees, the preset soil moisture is 20%; when the ambient temperature is between 30 degrees and 35 degrees, the preset soil moisture is 25%.

[0085] Optionally, the preset soil moisture is also related to the soil type. For example, when the soil type is sandy soil, the preset soil moisture is 15%; when the soil type is clay, the preset soil moisture is 25%.

[0086] Step S23: In the case where the number of detection points is greater than the preset number, an irrigation instruction is generated according to the soil moisture and the type of the green area.

[0087] The preset number is a constant, for example, the preset number is 80% of the total number of detection points in the green area.

[0088] The irrigation instruction includes at least one of irrigation duration, water flow rate, and water direction. The irrigation duration refers to the start duration of the irrigation device, the water flow rate refers to the water flow rate sprayed by the irrigation device, and the water direction refers to the direction of the spray head of the irrigation device.

[0089] Optionally, the type of the green area includes a slope and a flat ground.

[0090] For example, when the type of the green area is a flat ground, a difference between the ideal soil moisture and the soil moisture is calculated to obtain a soil moisture difference; a product of the area of the green area and the soil moisture difference is calculated to obtain a required water amount; a ratio of the required water amount and a preset water flow rate is calculated to obtain an irrigation duration, the preset water flow rate being a preset constant; and the preset water flow rate and the irrigation duration are integrated to obtain the irrigation instruction.

[0091] In the present application, the ideal soil moisture content refers to the optimal soil moisture content for maintaining the growth of vegetation in the green area. The ideal soil moisture content is related to the soil type and the vegetation type, and is an empirical value. For example, when the soil type is clay and the vegetation type is herbaceous plant, the ideal soil moisture content is 70%; when the soil type is sandy soil and the vegetation type is shrub, the ideal soil moisture content is 40%.

[0092] For example, when the type of the green area is a slope, the coverage of the water sprayed by the irrigation equipment on the slope is different from that on the flat ground due to the influence of the slope gradient. Therefore, when generating the irrigation instruction, the slope gradient needs to be considered to affect the coverage.

[0093] Step S24: Start the irrigation equipment according to the irrigation instruction, and the irrigation equipment is used to irrigate the green area.

[0094] The irrigation equipment has a one-to-one correspondence with the green area. The irrigation equipment can irrigate the vegetation in the corresponding green area.

[0095] Optionally, the irrigation equipment is arranged at the center position of the green area.

[0096] For example, when the irrigation instruction includes the irrigation duration, the water flow rate and the water direction, the irrigation equipment adjusts the water direction according to the irrigation instruction, and sprays water at the water flow rate. After the irrigation equipment works for the irrigation duration, the irrigation equipment is turned off.

[0097] In summary, by using the above technical solution, whether the green area needs to be irrigated is determined by detecting the soil moisture content of the point, and the green area can be precisely irrigated according to the actual situation of the green area, so that the irrigation efficiency is high.

[0098] In the following embodiments, when the type of the green area is a slope, the green area includes an uphill green area and a downhill green area, the height of the uphill green area is higher than that of the irrigation equipment, and the height of the downhill green area is lower than that of the irrigation equipment. Because of the influence of the slope gradient, the spray density of the uphill green area is different from that of the downhill green area, resulting in different time required for the uphill green area and the downhill green area to complete irrigation. Therefore, the present application discloses a green irrigation control method. Referring to Figure 3 The method comprises:

[0099] Step S301: According to the slope gradient, the water direction of the irrigation equipment and the water flow rate of the irrigation equipment, calculate the uphill irrigation density of the uphill green area and the downhill irrigation density of the downhill green area.

[0100] Irrigation density refers to the volume / mass of liquid received per second per unit area. Uphill irrigation density refers to the irrigation density of the uphill green area, and downhill irrigation density refers to the irrigation density of the downhill green area.

[0101] Water outlet direction refers to the angle between the nozzle of the irrigation device and the horizontal plane.

[0102] In this embodiment, the water outlet flow rate of the irrigation device is constant unless otherwise specified.

[0103] For example, refer to Figure 4 , let the slope angle be α, the water outlet angle be β, and the water outlet flow rate be Q. Since the liquid sprayed by the irrigation device has a high speed and a short trajectory in the air, the effect of air resistance on the speed of the liquid sprayed by the irrigation device can be ignored. Therefore, the irrigation device forms an elliptical irrigation range on the slope. Further, the motion curve of the sprayed liquid is simplified as a quadratic function, as shown in Figure 4 , the motion curve satisfies the function and where g represents the gravitational coefficient, and the slope surface satisfies the function y = -xtanθ. Therefore, by combining the above three function formulas, the two end points of the liquid on the slope are A and B, and the line segment AB is the major axis of the ellipse. The end points of the minor axis of the ellipse can be obtained by referring to the similar algorithm. According to OA, OB, and the length of the minor axis, the area of the uphill green area S1 and the area of the downhill green area S2 are determined. Further, the uphill irrigation density is ρ1 = Q / S1, and the downhill irrigation density is ρ2 = Q / S2.

[0104] Step S302: Calculate the uphill irrigation time according to the uphill irrigation density and the soil moisture content.

[0105] Uphill irrigation time refers to the time required to irrigate the uphill green area to the ideal soil moisture content.

[0106] For example, calculate the difference between the ideal soil moisture content and the soil moisture content to obtain the moisture content difference; obtain the unit area water demand according to the product of the moisture content difference and the water constant; calculate the ratio of the unit area water demand to the uphill irrigation density to obtain the uphill irrigation time. The water constant is used to represent the volume of water required to increase the soil moisture content of a unit area by 1%. For example, the water constant is 100.

[0107] For example, the ideal soil moisture content is θ, the soil moisture content is θ', the water constant is λ, and the uphill irrigation density is ρ1. Then the moisture content difference Δθ = θ - θ', and the unit area water demand V1 = Δθ * λ. Therefore, the uphill irrigation time T1 = V1 / ρ1.

[0108] Step S303: calculating the downhill irrigation time length according to the downhill irrigation density and the soil moisture content.

[0109] The downhill irrigation time length refers to the time required for irrigating the downhill green area to the ideal soil moisture content.

[0110] For example, the difference between the ideal soil moisture content and the soil moisture content is calculated to obtain the moisture content difference; the product of the moisture content difference and the water quantity constant is calculated to obtain the water quantity per unit area; and the ratio of the water quantity per unit area to the downhill irrigation density is calculated to obtain the downhill irrigation time length.

[0111] For example, the ideal soil moisture content is θ, the soil moisture content is θ', the water quantity constant is λ, and the uphill irrigation density is ρ2. Then the moisture content difference Δθ = θ - θ', the water quantity per unit area V2 = Δθ * λ, and the downhill irrigation time length T2 = V2 / ρ2.

[0112] Step S304: calculating the irrigation time length difference by calculating the difference between the downhill irrigation time length and the uphill irrigation time length.

[0113] Because the water spraying quantity of the irrigation equipment on the uphill green area and the downhill green area is the same, but the uphill green area is smaller than the downhill green area due to the slope gradient, the downhill irrigation density is smaller than the uphill irrigation density, and thus the downhill irrigation time length is greater than the uphill irrigation time length to make the soil moisture content reach the ideal moisture content.

[0114] For example, the uphill irrigation time length is T1, and the downhill irrigation time length is T2. Then the irrigation time length difference ΔT = T2 - T1.

[0115] Step S305: generating the first irrigation instruction according to the uphill irrigation time length and the water flow rate, the first irrigation instruction including an instruction for instructing the irrigation equipment to irrigate the green area.

[0116] The first irrigation instruction is used to instruct the irrigation equipment to spray water to the green area at the water flow rate, and the working time length of the irrigation equipment is the uphill irrigation time length.

[0117] Step S306: generating the second irrigation instruction according to the irrigation time length difference and the water flow rate, the first irrigation instruction including an instruction for instructing the irrigation equipment to irrigate the downhill green area.

[0118] The first irrigation instruction is used to instruct the irrigation equipment to spray water to the downhill green area at the water flow rate, and the working time length of the irrigation equipment is the downhill irrigation time length.

[0119] Step S307: integrating the first irrigation instruction and the second irrigation instruction to obtain the irrigation instruction.

[0120] For example, the first irrigation instruction and the second irrigation instruction can be encapsulated in a function (or container) to obtain the irrigation instruction. Alternatively, assembly instructions can be embedded in the first irrigation instruction and the second irrigation instruction to obtain the irrigation instruction.

[0121] In summary, by adopting the above technical solutions, when the green area is a slope, the irrigation instructions for the green area can be adjusted according to the characteristics of the slope, making the irrigation instructions more suitable for the characteristics of the slope.

[0122] exist Figure 3 In the illustrated embodiment, runoff is easily generated when irrigating vegetation on a slope, affecting the entire irrigation process. Runoff refers to the formation of water flow on the soil surface. Therefore, this application discloses a method for controlling irrigation in green areas. (Refer to...) Figure 5 The method includes:

[0123] Step S501: If the target soil moisture content corresponding to the target detection point is greater than the upper limit of moisture content, obtain the location of the target detection point.

[0124] The upper limit of soil moisture content refers to the maximum amount of water that soil can hold. When the soil moisture content reaches this upper limit, the soil no longer has the capacity to retain water, and runoff will form on the soil surface. The upper limit varies depending on the soil type. For example, the upper limit is 80% for sandy soil and 60% for clay soil. Therefore, when the soil moisture content of a target area exceeds the upper limit, runoff can be considered to have occurred in the area where the target monitoring point is located.

[0125] Step S502: If the target detection point is located in the downhill green area, then turn off the irrigation equipment.

[0126] When the target detection point is located in a downhill green area, due to the influence of... Figure 3 As shown in the embodiment, the downhill green area is more prone to runoff than the uphill green area. Therefore, when runoff occurs in the downhill green area, it is necessary to turn off the irrigation equipment and stop irrigating the green area.

[0127] Step S503: If the target detection point is located in the uphill greening area, calculate the total irrigation amount based on the downhill soil moisture content corresponding to the detection point in the downhill greening area.

[0128] Downhill soil moisture content refers to the average soil moisture content of the downhill greening area. For example, the soil moisture content detected at various monitoring points within the downhill greening area is obtained; the average of the aforementioned soil moisture content is calculated to obtain the total irrigation amount.

[0129] For example, the difference between the ideal soil moisture content and the downhill soil moisture content is calculated to obtain a moisture content difference; the product of the area of the downhill green area and the moisture content difference is calculated to obtain the total irrigation amount.

[0130] Step S504: The water flow rate is updated according to the total irrigation amount and the target soil moisture content to obtain a target water flow rate.

[0131] For example, the product of the target soil moisture content and the permeation constant is calculated to obtain a permeation water amount; the difference between the total irrigation amount and the permeation water amount is calculated to obtain an optimized irrigation water amount; the product of the water flow rate and the remaining irrigation time is calculated to obtain a total irrigation water amount; the difference between the total irrigation water amount and the optimized irrigation water amount is calculated to obtain an irrigation water amount; and the ratio of the irrigation water amount to the remaining irrigation time is calculated to obtain the target water flow rate. The permeation parameter is an empirical value, and the permeation parameter is positively correlated with the target soil moisture content. The permeation parameter refers to the water amount that a unit area of soil region with a soil moisture content greater than the upper limit of the soil moisture content can permeate to an adjacent soil region.

[0132] In another implementation of the embodiment, the remaining irrigation time is updated according to the total irrigation amount and the target soil moisture content to obtain a target remaining irrigation time.

[0133] Step S505: The irrigation equipment is controlled to irrigate the downhill green area at the target water flow rate, and the irrigation equipment is controlled to stop irrigating the uphill green area.

[0134] For example, the irrigation equipment is first controlled to stop irrigating the uphill green area, and then the irrigation equipment is controlled to irrigate the downhill green area at the target water flow rate.

[0135] In summary, according to the different positions of the target detection points in the green area, the irrigation strategy of the irrigation equipment is adjusted to make the irrigation strategy more in line with the actual situation.

[0136] In Figure 3 In the embodiment shown in the figure, when the vegetation on the slope is irrigated, the vegetation height will affect the irrigation effect. When the vegetation is too high, the liquid sprayed by the irrigation equipment is difficult to pass through the vegetation, resulting in the irrigation equipment being unable to irrigate the soil behind the vegetation. Therefore, the embodiment of the present application discloses a green irrigation control method. Referring to Figure 6 , the method comprises:

[0137] Step S601: Obtain a real-time image of a green area.

[0138] For example, the real-time image of the green area is obtained by a camera, and then the camera sends the real-time image to a control device.

[0139] Step S602: Obtain a position of vegetation with a vegetation height greater than a preset height in the real-time image.

[0140] In the embodiment, the preset height is related to the vegetation position. When the height of the vegetation is greater than the preset height, the liquid sprayed by the irrigation equipment cannot pass through the vegetation.

[0141] Step S603: If the vegetation position is located in the downhill greening area, calculate the relative distance between the irrigation equipment and the vegetation position.

[0142] The relative distance refers to the distance between the projection point of the irrigation equipment on the slope and the projection point of the vegetation position on the slope.

[0143] For example, by using the real-time image, the first spatial coordinates of the irrigation equipment and the second spatial coordinates of the vegetation are obtained; and according to the first spatial coordinates and the second spatial coordinates, the relative distance between the irrigation equipment and the vegetation position is calculated.

[0144] Step S604: According to the relative distance and the slope gradient, the water outlet angle of the irrigation equipment and the expected water outlet flow rate are calculated.

[0145] The irrigation equipment sprays liquid according to the water outlet angle and the expected water outlet flow rate, so that the liquid sprayed by the irrigation equipment can reach the bottom of the vegetation.

[0146] In some embodiments, the expected water outlet flow rate is an empirical value.

[0147] Step S605: According to the water outlet angle and the expected water outlet flow rate, the irrigation equipment is controlled to irrigate at the vegetation position.

[0148] For example, according to the water outlet angle and the expected water outlet flow rate, the irrigation equipment is controlled to irrigate at the vegetation position, so that the vegetation forms runoff at the projection on the slope.

[0149] Further, according to the water outlet angle and the expected water outlet flow rate, the irrigation equipment is continuously controlled to irrigate at the vegetation position; a real-time image of the vegetation position is obtained; whether runoff is generated at the vegetation position is identified by using the real-time image; in the case that runoff is generated, the downhill soil moisture content measured by the detection point in the downhill greening area is obtained; and after the downhill soil moisture content reaches the ideal soil moisture content, the irrigation equipment is turned off.

[0150] In summary, by using the above technical solution, when the height of the vegetation is too high, the irrigation equipment is controlled to irrigate at the vegetation position, so that the water mist can be liquefied on the vegetation and form runoff, and the plants behind the vegetation are indirectly irrigated by the runoff.

[0151] In the following embodiments, during the use of the irrigation equipment, the irrigation equipment may be damaged, which affects the normal irrigation of the greening area. Therefore, the embodiment of the present application discloses a greening irrigation control method. Referring to Figure 7 The method comprises:

[0152] Step S701: In the case of irrigation equipment failure, the wind direction and wind speed are acquired.

[0153] For example, if the actual water flow of the irrigation equipment is different from the water flow provided by the irrigation instruction, it is considered that the irrigation equipment is malfunctioning. For example, if the irrigation equipment can still detect the actual water flow in the off state, it is considered that the irrigation equipment is malfunctioning. Further, if the irrigation equipment is malfunctioning, the irrigation equipment will not be started.

[0154] For example, the wind direction and wind speed are acquired by a meteorological sensor.

[0155] Step S702: Determine the candidate irrigation equipment in the opposite direction of the wind direction with the irrigation equipment as the origin.

[0156] For example, please refer to Figure 8 , the irrigation equipment 801 is located in the green area 802, and the arrow direction in the figure represents the wind direction. When the irrigation equipment 801 fails, the candidate irrigation equipment in the opposite direction of the wind direction with the irrigation equipment 801 as the origin is the irrigation equipment 803 and the irrigation equipment 805.

[0157] Step S703: Calculate the maximum irrigation range of the candidate irrigation equipment according to the wind speed and the candidate irrigation equipment.

[0158] The irrigation range of the irrigation equipment will be affected by the wind direction. Please refer to Figure 8 , under the condition of no wind, the maximum irrigation range of the irrigation equipment 803 is the area 804, and under the condition of applying the wind field, the maximum irrigation range of the irrigation equipment 803 becomes the area 805.

[0159] Step S704: Select the first irrigation equipment from the candidate irrigation equipment, and the maximum irrigation range of the first irrigation equipment covers the green area.

[0160] For example, please refer to Figure 8 , the irrigation equipment 803 and the irrigation equipment 805 are both candidate irrigation equipment, but the maximum coverage range of the irrigation equipment 803 is the area 805, which completely covers the green area 802, while the maximum coverage range of the irrigation equipment 805 is the area 806, which does not completely cover the green area 802.

[0161] In some embodiments, if there is no first irrigation equipment in the candidate irrigation equipment, the embodiment will select a second irrigation equipment so that as many areas as possible in the green area are irrigated. The embodiment of the present application discloses a green irrigation control method. Please refer to Figure 9 , the method comprises:

[0162] Step S7041: In the case that the first irrigation device does not exist in the candidate irrigation devices, a second irrigation device is selected from the candidate irrigation devices, the maximum irrigation range of the second irrigation device has an overlapping region with the green area, and the maximum irrigation range of the second irrigation device does not cover the green area.

[0163] For example, referring to Figure 8 , the maximum irrigation range of the irrigation device 805 has an overlapping region with the green area 802, but does not cover the green area 802.

[0164] Step S7042: If there is only one second irrigation device, the second irrigation device is started to make the irrigation range of the second irrigation device reach the maximum irrigation range.

[0165] For example, referring to Figure 8 , there is only the irrigation device 805 as the second irrigation device, so the irrigation device 805 is started to make the irrigation range of the irrigation device 805 reach the maximum irrigation range, so that the irrigation device 805 can cover as much as possible of the green area 801.

[0166] Step S7043: If there are at least two second irrigation devices, it is determined whether there is an overlapping region between the second irrigation devices.

[0167] If there is an overlapping region between the second irrigation devices, step S7045 is performed.

[0168] If there is no overlapping region between the second irrigation devices, step S7044 is performed.

[0169] Step S7044: If there is no overlapping region between the maximum irrigation ranges of the second irrigation devices, the second irrigation devices are started to make the irrigation range of the second irrigation devices reach the maximum irrigation range.

[0170] Similar to step S7042, if there is no overlapping region between the maximum irrigation ranges of the at least two second irrigation devices, the second irrigation devices are started to make the irrigation range of the second irrigation devices reach the maximum irrigation range, so that the liquid sprayed by the second irrigation devices can cover the green area as much as possible.

[0171] Step S7045: If there is an overlapping region between the maximum irrigation ranges of the second irrigation devices, the second irrigation devices are combined two by two to obtain a set of irrigation device combinations.

[0172] For example, assuming that the second irrigation devices include A, B, C, and D, the second irrigation devices are combined two by two to obtain a set of irrigation device combinations {(A, B), (A, C), (A, D), (B, C), (B, D), (C, D)}.

[0173] Step S7046: Calculate the union area of the maximum irrigation range of each irrigation equipment combination in the irrigation equipment combination set in the green area.

[0174] For example, the union irrigation area of the maximum irrigation range of each irrigation equipment combination in the irrigation equipment combination set is calculated; the union of the union irrigation area and the green area is calculated to obtain the union area.

[0175] Step S7047: Take the target irrigation equipment combination corresponding to the maximum union area in the union area.

[0176] The maximum union area is the area with the largest area in the union area, and the target irrigation equipment combination can make as many areas in the green area as possible be irrigated when working.

[0177] Step S7048: Start the target irrigation equipment combination to make the irrigation range of the target irrigation equipment combination reach the maximum irrigation range.

[0178] For example, the target irrigation equipment combination is started to make the irrigation range of the target irrigation equipment combination reach the maximum irrigation range, so that the liquid sprayed by the target irrigation equipment combination can cover the green area as much as possible.

[0179] Step S705: Turn on the first irrigation equipment to make the irrigation area of the first irrigation equipment cover the green area.

[0180] For example, please refer to Figure 8 , turn on the irrigation equipment 803 to make the irrigation area of the irrigation equipment 803 cover the green area 802.

[0181] In summary, by using the above technical solution, when the irrigation equipment fails, the first irrigation equipment is started by using the wind direction and wind speed, and the first irrigation equipment is used to temporarily irrigate the green area, which can temporarily meet the irrigation demand of the green area.

[0182] In the following embodiments, the meteorological information of the region where the green area is located also affects the soil water content, so that the irrigation method of the irrigation equipment changes. Embodiments of the present application disclose a green irrigation control method. Referring to Figure 10 , the method comprises:

[0183] Step S1001: Obtain meteorological information of the region where the green area is located.

[0184] The meteorological information includes at least one of rainfall information, rainfall period, and temperature change curve.

[0185] For example, the control device sends a meteorological information request to the server; the server returns the meteorological information to the control device.

[0186] The server sends the weather information to the control device every preset time length.

[0187] Step S1002: predicting the soil moisture content change trend of the green area according to the weather information and the soil moisture content.

[0188] The soil moisture content change trend is used to represent the trend of the soil moisture content of the green area changing over time.

[0189] The natural evaporation curve of the soil moisture content is generated according to the temperature change curve, and the natural evaporation curve is used to represent the loss amount of the soil moisture content of the green area caused by natural evaporation.

[0190] The rainfall addition curve of the soil moisture content is generated according to the rainfall information and the rainfall period, and the rainfall addition curve is used to represent the increase amount of the soil moisture content of the green area caused by rainfall.

[0191] The soil moisture content change trend of the green area is generated according to the natural evaporation curve and the rainfall addition curve.

[0192] Step S1003: setting the total irrigation water amount and the irrigation time according to the soil moisture content change trend and the weather information.

[0193] The candidate irrigation time point of the soil moisture content in the soil moisture content change trend being less than the preset soil moisture content is obtained; whether there is rainfall in the future period after the candidate irrigation time point is determined according to the weather information; if there is rainfall, the irrigation device is not started; and if there is no rainfall, the irrigation device is started.

[0194] According to the above technical scheme, the total irrigation water amount and the irrigation time of the irrigation device are adjusted through the weather information, so that the use of the irrigation device is more in line with the actual demand, and the irrigation efficiency is higher.
