Description

Technical Field

[0001] The present invention relates to the field of artificial intelligence technology, and in particular to a garden irrigation intelligent analysis system and method. Background Art

[0002] Intelligent analysis of garden irrigation is a technology that uses modern information technology to intelligently manage and optimize the garden irrigation process. By deploying various sensors in the garden, it collects environmental data such as soil moisture, temperature, light intensity, wind speed, precipitation, and plant growth status information in real time to provide a basis for subsequent irrigation decisions. Water meters or other flow sensors are installed to dynamically monitor irrigation water consumption in order to analyze the efficiency of water resource use. The large amount of collected data is uploaded to the cloud or local server, and processed and analyzed using data analysis technology and algorithms.

[0003] At present, garden irrigation projects require a lot of manpower during irrigation, and it is impossible to intelligently track whether the irrigation position of the garden is normal throughout the process. In particular, the impact of power start and stop will cause the irrigation spray position to deviate, affecting the normal irrigation of the garden. At the same time, when the garden irrigation is unmanned, it is impossible to judge whether the irrigation status is abnormal in real time according to the soil moisture replenishment, resulting in the inability to timely judge whether the current irrigation mode is executable according to the irrigation status. In addition, due to the changeable weather, especially the unexpected situation of showers irrigating the garden, when natural rainwater irrigation occurs, it is impossible to timely judge whether the garden irrigation meets the irrigation needs, and the remaining irrigation volume of the garden irrigation to meet the needs. It is not convenient to automatically adjust the irrigation parameters according to weather changes, resulting in water resources waste in garden irrigation, weak energy-saving effect, and the inability to guarantee the accuracy of garden irrigation.

[0004] Therefore, a garden irrigation intelligent analysis system and method are proposed to solve the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide a garden irrigation intelligent analysis system and method to solve the problems raised in the above background.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a garden irrigation intelligent analysis system and method, including an irrigation area monitoring terminal, an irrigation mode analysis terminal and an irrigation analysis correction terminal;

[0007] The irrigation area monitoring terminal is used to collect the irrigation status of the garden within the irrigation area in real time through a data acquisition instrument, and judge whether the irrigation meets the standard in real time by combining the area and the irrigation flow rate, and judge whether the irrigation position deviates in real time by real-time monitoring the spray position of the garden irrigation;

[0008] The irrigation mode analysis terminal is used to set different irrigation modes for different time periods for the irrigation area, analyze the irrigation status of the corresponding time period in real time in combination with the irrigation position and the soil moisture replenishment, and timely determine whether the irrigation mode can continue to be executed;

[0009] The irrigation analysis and correction end is used to combine weather changes and rainwater irrigation warning information to analyze in real time whether garden irrigation meets the demand, and timely calculate the garden irrigation amount under weather changes and rainwater irrigation warning information, timely judge whether garden irrigation meets the irrigation demand according to the warning information, and automatically adjust the garden irrigation parameters.

[0010] The irrigation area monitoring terminal includes an area range setting module, an irrigation position abnormality monitoring module and an irrigation status judgment module;

[0011] The area range setting module is used to set the garden irrigation area range. The garden irrigation area range formulates the irrigation flow rate according to the area of ​​the area, and sets the irrigation flow rate to three levels, the first level is slow, the second level is standard flow rate, and the third level is fast. The slow irrigation spray area is smaller than the standard flow rate irrigation spray area, and the standard flow rate irrigation spray area is smaller than the fast irrigation spray area.

[0012] The irrigation position abnormality monitoring module is used to collect the irrigation status of the garden within the irrigation area in real time through a data acquisition instrument. The irrigation status includes the irrigation area, irrigation flow rate, irrigation stage and irrigation duration.

[0013] The irrigation status judgment module is used to judge whether the irrigation meets the standard in real time based on the area and irrigation flow rate, and calculate the garden irrigation flow rate in real time. The calculation formula is as follows:

[0014]

[0015] Among them, γ represents the garden irrigation flow rate at the current moment, V represents the garden irrigation water volume at the current moment, A represents the garden irrigation area at the current moment, and t represents the garden irrigation time at the current moment;

[0016] Calculate the irrigation volume within the area of ​​the region using the following formula:

[0017] Irrigation amount = ET0 × Kc- rainfall × rainfall utilization coefficient;

[0018] Among them, ET0 represents the reference crop evapotranspiration, which can be obtained through meteorological data, Kc represents the crop coefficient, which depends on the plant species and growth stage, the rainfall utilization coefficient is usually 0.7 to 0.9, depending on the soil and vegetation conditions, and the irrigation amount represents the garden irrigation amount at the current moment within the regional scope;

[0019] Set the standard garden irrigation volume and standard garden irrigation flow rate, and calculate the difference between the calculated garden irrigation volume and garden irrigation flow rate and the standard garden irrigation volume and standard garden irrigation flow rate respectively. If the difference is less than 1 and greater than 0, it means that the irrigation meets the standard, otherwise, it means that the irrigation does not meet the standard;

[0020] By setting multiple groups of cameras to capture the garden irrigation sprinklers in real time, the spray angle correction values ​​of multiple sprinklers are calculated in real time to determine whether the sprinkler position of the garden irrigation is abnormal. The judgment method is as follows:

[0021] Calculate the wind force correction value Δθ at the sprinkler location w , the formula is as follows:

[0022] Δθ w =k w ×v;

[0023] Where: Δθ w Indicates the wind force correction value, k w It represents the wind force coefficient, which is usually 0.5 to 2. The specific value needs to be determined according to the nozzle type and environment. v represents the wind speed.

[0024] Calculate the slope correction value Δθ at the sprinkler position s , the formula is as follows:

[0025] Δθ s =k s ×s;

[0026] Among them, k s It indicates the slope coefficient. The slope height is usually 0.1 to 0.5, which is determined by the nozzle type and slope. s indicates the slope.

[0027] Calculate the height correction value Δθ of the spray position h , the formula is as follows:

[0028] Δθ h =k h ×h;

[0029] Among them, k h It indicates the installation height coefficient, which is usually 0.05-0.2. The specific value needs to be determined according to the nozzle type. h indicates the installation height of the nozzle.

[0030] Calculate the injection angle correction value of the corresponding nozzle, the formula is as follows:

[0031] Δθ=Δθ w +Δθ s +Δθ h ;

[0032] If Δθ is equal to 0, it is judged that the spraying position of the garden irrigation is normal. If Δθ is not equal to 0, it is judged that the spraying position of the garden irrigation is abnormal.

[0033] The irrigation mode analysis terminal includes a time period mode synchronization module, an irrigation period judgment module and an irrigation mode adjustment module;

[0034] The time period mode synchronization module is used to set different irrigation modes for different time periods in the irrigation area. The irrigation mode includes setting the irrigation flow rate, irrigation area, spray angle and irrigation duration, and receiving the abnormal judgment result of the irrigation position in real time through the data receiver.

[0035] The irrigation period judgment module is used to calculate in real time the irrigation parameter abnormal value Z of different irrigation positions and soil moisture replenishment in the corresponding area under different irrigation modes in different time periods. The calculation formula is as follows:

[0036]

[0037] Among them, x represents the actual data of soil moisture replenishment at the corresponding irrigation position, μ represents the mean, σ represents the standard deviation of soil moisture replenishment at the corresponding irrigation position. If the absolute value of Z is greater than 1 and less than or equal to 2, it means that the irrigation parameters are normal. If the absolute value of Z is greater than 2, it means that the irrigation parameters are abnormal, and the reporting system issues an irrigation early warning signal.

[0038] The irrigation mode adjustment module is used to calculate the soil moisture replenishment amount I in real time when the irrigation parameters are abnormal. The calculation formula is as follows:

[0039] I=(θ fc -θ 当前 )×D×A+ET-Pe;

[0040] Among them, θ fc represents the field water capacity, θ 当前 represents the current soil moisture content, D represents the root layer depth, A represents the irrigation area, ET represents the water requirement of garden plants, and Pe represents the effective rainfall at the corresponding time;

[0041] Irrigation parameters are adjusted in real time based on the calculated soil moisture replenishment.

[0042] The irrigation analysis and correction terminal includes a weather change monitoring module, an environmental early warning irrigation anomaly module and a garden irrigation adjustment module;

[0043] The weather change monitoring module is used to monitor the weather changes within the irrigation area in real time through weather forecast and environmental detectors, and record them in real time through data recorders.

[0044] The environmental warning irrigation anomaly module is used to combine weather changes and rainwater irrigation warning information to calculate the garden irrigation demand ETa within the area in real time. The calculation formula is as follows:

[0045] ETa=ET×(1+ktΔT+kwΔw-khΔH);

[0046] Among them, ET represents the water requirement of garden plants, kt represents the temperature adjustment coefficient, ΔT represents the temperature change, kw represents the wind speed adjustment coefficient, Δw represents the wind speed change, kh represents the humidity adjustment coefficient, ΔH represents the humidity change;

[0047] If the irrigation volume in the corresponding area is greater than 0, it means that irrigation is needed. If the irrigation volume in the corresponding area is less than or equal to 0, it means that no irrigation is needed. Calculate the natural irrigation volume P under weather changes e , the calculation formula is as follows:

[0048] Pe = rainfall × rainfall utilization coefficient - evaporation loss;

[0049] Among them, rainfall is obtained through meteorological data or rainfall sensors. The rainfall utilization coefficient indicates the proportion of rainfall that can be effectively used by soil and plants, which is usually 0.7 to 0.9, depending on soil type, slope and vegetation cover. Evaporation loss is the evaporation caused by weather changes. The actual value of garden irrigation is obtained by subtracting the garden irrigation demand from the natural irrigation amount.

[0050] The garden irrigation adjustment module is used to automatically adjust irrigation parameters according to actual garden irrigation values, and track irrigation anomalies in real time through a data tracker.

[0051] A garden irrigation intelligent analysis method comprises the following steps:

[0052] Step 1: First, configure the remote-controlled garden irrigation intelligent analysis service system, enter the irrigation area monitoring terminal, set the garden irrigation area range, collect the irrigation status within the irrigation area in real time, and judge whether the irrigation meets the standard in real time through the area and irrigation flow rate. And through real-time monitoring of the irrigation spray position, judge whether the irrigation position is abnormal in real time, and monitor whether the irrigation position is abnormal throughout the whole process;

[0053] Step 2: Enter the irrigation mode analysis terminal, set different irrigation modes for different time periods, receive the abnormal judgment results of the irrigation position in real time, analyze the irrigation status of the corresponding time period in real time, and promptly judge whether the irrigation mode can continue to be executed;

According to the warning information, it is timely judged whether the garden irrigation meets the irrigation demand and automatically adjusts the garden irrigation parameters.

[0069] The irrigation area monitoring terminal includes an area range setting module, an irrigation position abnormality monitoring module and an irrigation status judgment module;

[0070] The area range setting module is used to set the garden irrigation area range. The garden irrigation area range formulates the irrigation flow rate according to the area of ​​the area, and sets the irrigation flow rate to three levels. The first level is slow, the second level is standard flow rate, and the third level is fast. The slow irrigation spray area is smaller than the standard flow rate irrigation spray area, and the standard flow rate irrigation spray area is smaller than the fast irrigation spray area.

The irrigation status includes irrigation area, irrigation flow rate, irrigation stage and irrigation duration.

[0072] The irrigation status judgment module is used to judge whether the irrigation meets the standard in real time based on the area and irrigation flow rate, and calculate the garden irrigation flow rate in real time. The calculation formula is as follows:

[0073]

[0074] Among them, γ represents the garden irrigation flow rate at the current moment, V represents the garden irrigation water volume at the current moment, A represents the garden irrigation area at the current moment, and t represents the garden irrigation time at the current moment;

[0075] Calculate the irrigation volume within the area of ​​the region using the following formula:

[0091] If Δθ is equal to 0, it is judged that the spray position of garden irrigation is normal. If Δθ is not equal to 0, it is judged that the spray position of garden irrigation is abnormal. By real-time monitoring of the spray position of garden irrigation, it is judged in real time whether the irrigation position deviates, so that the system can monitor the irrigation position in real time throughout the whole process to see if it is abnormal. In particular, if the irrigation spray position deviates due to the impact of power start and stop, it can be discovered in time to avoid affecting the normal irrigation of the garden, thereby further increasing the accuracy of the garden irrigation position.

If the irrigation volume in the corresponding area is less than or equal to 0, it means that no irrigation is needed. Calculate the natural irrigation volume P under weather changes e , the calculation formula is as follows:
