Description

Technical Field

[0001] The present invention relates to the technical field of scheduling management, and in particular to an irrigation area water scheduling method, system and equipment based on multi-factor coordination. Background Art

[0002] Resource management is a complex system involving multiple aspects and levels. This complexity is particularly evident in irrigation areas. As the basic unit of agricultural production management, water scheduling in irrigation areas is not only related to the stability and efficiency of agricultural production, but also directly affects the sustainable use of water resources and the balance of the ecological environment. Therefore, water scheduling needs to comprehensively consider multiple goals, including irrigation benefits, water resource utilization efficiency, and ecological and environmental protection.

[0003] For example, the invention patent with announcement number CN107808253B announces a real-time water distribution method for irrigation canals based on a coordination algorithm, including the steps of 1) reporting water demand plans based on the water demand of water users in the irrigation area; 2) establishing a real-time water distribution scheduling model when the total water volume in the irrigation area is less than the total water demand of water users; 3) constructing a Hamiltonian function to find the optimal solution for allocating water to each water user; 4) scheduling the flow and gate opening allocated to each water user based on the optimal solution.

[0004] For example, the invention patent with announcement number CN105868868B announces a method for regulating and identifying risks in the operation process of a water network water resource system, which is characterized in that irrigation water demand information is provided for a regional multi-water source optimization configuration model based on real-time perception information, and a real-time water distribution decision model determines the real-time water demand; a medium- and long-term runoff forecast model is used to predict the monthly runoff of a basin in the future; a downscaled climate model provides input for a short- and medium-term hydrological forecast model; a groundwater simulation forecast model is used to regulate groundwater levels; a coupled forecast multi-water source optimization scheduling model combines all the above information to achieve joint scheduling of multiple water sources; a multi-water source scheduling model provides daily runoff water distribution decisions, and water is transported through a water resource transmission automatic control unit to achieve precise distribution.

[0005] In combination with the above technical solutions, it is found that there is an irrigation area water resource scheduling plan, which directly conducts comprehensive water resource scheduling for the entire irrigation area. However, in fact, due to the diversity of water resource demands in each irrigation area and the presence of many influencing factors in the transportation process, the water resource scheduling efficiency will be greatly reduced in the irrigation area water resource scheduling, and ultimately the irrigation area water volume scheduling cannot be coordinated. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides an irrigation area water scheduling method, system and equipment based on multi-factor coordination, which can effectively solve the problems involved in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: In the first aspect, the present invention provides an irrigation area water scheduling method based on multi-factor coordination, including: growth characteristic evaluation: the crop growth monitoring component monitors the growth status of the crops in each sub-irrigation area in real time, collects the growth data of the crops in each sub-irrigation area, determines the growth characteristic evaluation value of the crops in each sub-irrigation area, matches the estimated water demand of the crops in each sub-irrigation area and the estimated irrigation period of the crops in each sub-irrigation area, and uploads them to the irrigation area water resource scheduling component; water resource estimated loss: the meteorological data monitoring component monitors the meteorological environment of each sub-irrigation area, collects the real-time meteorological characteristic data of each sub-irrigation area during the estimated irrigation period of the crops in each sub-irrigation area, and evaluates the water demand of the crops in each sub-irrigation area and the estimated irrigation period of the crops in each sub-irrigation area. The meteorological characteristic impact value of each sub-irrigation area during the estimated irrigation period is matched to obtain the estimated water resource loss of each sub-irrigation area during the estimated irrigation period, and uploaded to the irrigation area water resource scheduling component; irrigation area scheduling status determination: the irrigation area water resource scheduling component monitors the water resources of the irrigation area in real time, collects water supply data of each water transfer channel in the irrigation area during the estimated irrigation period of the crops in each sub-irrigation area, and comprehensively considers the estimated water demand of the crops in each sub-irrigation area and the estimated water resource loss of each sub-irrigation area during the estimated irrigation period, evaluates the scheduling quality indicators of each water transfer channel in the irrigation area during the estimated irrigation period, and compares them with the predefined scheduling quality reference indicators, so as to determine the scheduling status of each water transfer channel in the irrigation area during the estimated irrigation period, and provide feedback on the irrigation area water scheduling.

[0008] As a further method, the growth characteristic evaluation value of the crops in each sub-irrigation area is determined, and the specific determination process is as follows: the growth data of the crops in each sub-irrigation area specifically include the crop height of each crop in each sub-irrigation area at the characteristic monitoring time point, the number of leaves of each crop in each sub-irrigation area at the characteristic monitoring time point, the total chlorophyll content of the leaves of each crop in each sub-irrigation area at the characteristic monitoring time point, the corresponding area of ​​each leaf of each crop in each sub-irrigation area at the characteristic monitoring time point, and the corresponding length of each root system of each crop in each sub-irrigation area at the characteristic monitoring time point; the corresponding area of ​​each leaf of each crop in each sub-irrigation area at the characteristic monitoring time point is added up to obtain the corresponding area of ​​each crop in each sub-irrigation area at the characteristic monitoring time point. the total leaf area of ​​each crop plant at the characteristic monitoring time point; the corresponding lengths of each root system of each crop plant in each sub-irrigation area at the characteristic monitoring time point are added up to obtain the total root length of each crop plant in each sub-irrigation area at the characteristic monitoring time point; the crop plant height of each crop plant in each sub-irrigation area at the characteristic monitoring time point, the number of leaves of each crop plant in each sub-irrigation area at the characteristic monitoring time point, the total chlorophyll content of leaves of each crop plant in each sub-irrigation area at the characteristic monitoring time point, the total leaf area of ​​each crop plant in each sub-irrigation area at the characteristic monitoring time point and the total root length of each crop plant in each sub-irrigation area at the characteristic monitoring time point are comprehensively analyzed to obtain the growth characteristic evaluation value of the crops in each sub-irrigation area.

[0009] As a further method, the matching obtains the estimated water requirement of the crops in each sub-irrigation area and the estimated irrigation period of the crops in each sub-irrigation area. The specific matching process is: matching the growth characteristic evaluation values ​​of the crops in each sub-irrigation area with the estimated water requirement corresponding to the predefined growth characteristic evaluation value intervals, thereby obtaining the estimated water requirement of the crops in each sub-irrigation area; matching the growth characteristic evaluation values ​​of the crops in each sub-irrigation area with the estimated irrigation period corresponding to the predefined growth characteristic evaluation value intervals, thereby obtaining the estimated irrigation period of the crops in each sub-irrigation area.

[0010] As a further method, the meteorological characteristic impact value of each sub-irrigation area during the estimated irrigation period is evaluated, and the specific evaluation process is as follows: the real-time meteorological characteristic data of each sub-irrigation area specifically include the real-time sunshine intensity of each sub-irrigation area during the estimated irrigation period, the real-time environmental wind speed of each sub-irrigation area during the estimated irrigation period, the real-time environmental temperature of each sub-irrigation area during the estimated irrigation period, and the real-time water vapor evaporation of each sub-irrigation area during the estimated irrigation period; the total chlorophyll content of each crop in each sub-irrigation area at the characteristic monitoring time point is matched with the sunshine reference intensity corresponding to the predefined total chlorophyll content interval of each leaf, so as to obtain the sunshine reference intensity corresponding to each crop in each sub-irrigation area, perform mean processing to obtain and record it as the mean sunshine reference intensity of each sub-irrigation area; the total chlorophyll content of each crop in each sub-irrigation area at the characteristic monitoring time point is matched with the sunshine reference intensity corresponding to the predefined total chlorophyll content interval of each leaf, so as to obtain the sunshine reference intensity corresponding to each crop in each sub-irrigation area, perform mean processing to obtain and record it as the mean sunshine reference intensity of each sub-irrigation area The total root length is matched with the environmental reference temperature corresponding to each predefined root total length interval, so as to obtain the mean environmental reference temperature corresponding to each crop in each sub-irrigation area, and the mean value is processed to obtain and record it as the mean environmental reference temperature of each sub-irrigation area; the soil type of each sub-irrigation area is obtained, and the soil characteristic influence coefficient corresponding to each predefined soil type is matched to obtain the soil characteristic influence coefficient of each sub-irrigation area; the real-time sunshine intensity of each sub-irrigation area in the estimated irrigation period, the real-time environmental wind speed of each sub-irrigation area in the estimated irrigation period, the real-time environmental temperature of each sub-irrigation area in the estimated irrigation period, the real-time water vapor evaporation of each sub-irrigation area in the estimated irrigation period and the soil characteristic influence coefficient of each sub-irrigation area are comprehensively analyzed to obtain the meteorological characteristic influence value of each sub-irrigation area in the estimated irrigation period. The specific analysis method is as follows:

[0011] In the formula, is the meteorological characteristic impact value of the g-th sub-irrigation area during the estimated irrigation period, g is the number of each sub-irrigation area, , G is the total amount of the sub-irrigation area, t is the time variable, , To estimate the start time of the irrigation period, To estimate the end time of the irrigation period, is the real-time sunshine intensity of the g-th sub-irrigation area at the t-th moment during the estimated irrigation period, is the mean reference sunshine intensity of the g-th sub-irrigation area, is the real-time ambient temperature of the g-th sub-irrigation area at the t-th moment during the estimated irrigation period, is the mean ambient reference temperature of the g-th sub-irrigation area, is the real-time ambient wind speed of the g-th sub-irrigation area at the t-th moment during the estimated irrigation period, is the real-time water vapor evaporation of the g-th sub-irrigation area at the t-th moment during the estimated irrigation period, is the soil characteristic influence coefficient of the g-th irrigation area, It is the meteorological characteristic parameter corresponding to the real-time ambient wind speed predefined in the irrigation area dispatch information database. It is the meteorological characteristic parameter corresponding to the real-time water vapor evaporation predefined in the irrigation area scheduling information database.

[0012] As a further method, the matching obtains the estimated water resource loss of each sub-irrigation area during the estimated irrigation period. The specific matching process is: matching the meteorological characteristic influence value of each sub-irrigation area during the estimated irrigation period with the estimated water resource loss corresponding to the predefined meteorological characteristic influence value interval. The specific matching process is: obtaining a mapping set between the meteorological characteristic influence value of each sub-irrigation area during the estimated irrigation period and the estimated water resource loss from the irrigation area scheduling information database, determining the interval to which the meteorological characteristic influence value of each sub-irrigation area during the estimated irrigation period belongs, and allocating the estimated water resource loss corresponding to the interval to each sub-irrigation area corresponding to the meteorological characteristic influence value, thereby matching to obtain the estimated water resource loss of each sub-irrigation area during the estimated irrigation period.

[0013] As a further method, the scheduling status of each water transfer channel in the irrigation area during the estimated irrigation period is determined, and the specific determination process is: comparing the scheduling quality index of each water transfer channel in the irrigation area during the estimated irrigation period with the predefined scheduling quality reference indexes. If the scheduling quality index of a water transfer channel in the irrigation area during the estimated irrigation period is greater than or equal to the scheduling quality reference index, then the scheduling status of the water transfer channel in the irrigation area during the estimated irrigation period is determined to be a normal scheduling status. If the scheduling quality index of a water transfer channel in the irrigation area during the estimated irrigation period is less than the scheduling quality reference index, then the scheduling status of the water transfer channel in the irrigation area during the estimated irrigation period is determined to be an abnormal scheduling status, and feedback is given to the abnormal scheduling status.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Reference Figure 1 As shown, the first aspect of the present invention provides an irrigation area water scheduling method based on multi-factor coordination, including: growth characteristic evaluation: the crop growth monitoring component monitors the growth status of the crops in each sub-irrigation area in real time, collects the growth data of the crops in each sub-irrigation area, determines the growth characteristic evaluation value of the crops in each sub-irrigation area, matches the estimated water demand of the crops in each sub-irrigation area and the estimated irrigation period of the crops in each sub-irrigation area, and uploads them to the irrigation area water resource scheduling component.

[0026] The above-mentioned crop growth monitoring component includes a chlorophyll fluorescence sensor that can measure the chlorophyll fluorescence characteristics of crops; the drone monitoring sensor can obtain image information of crops, such as plant height, number of leaves, planting density, etc. The crop growth monitoring component also has an image analysis function, which can process and analyze the collected images and automatically calculate parameters such as crop coverage and leaf area; the crop growth monitoring component can centrally collect and preliminarily process the data collected by various sensors, convert analog signals into digital signals, and transmit the data collected by the data collector to the irrigation area water resource scheduling component.

[0027] Specifically, the growth characteristic evaluation value of the crops in each sub-irrigation area is determined by:

[0028] The growth data of the crops in each sub-irrigation area specifically include the plant height of each crop in each sub-irrigation area at the characteristic monitoring time point, the number of leaves of each crop in each sub-irrigation area at the characteristic monitoring time point, the total chlorophyll content of the leaves of each crop in each sub-irrigation area at the characteristic monitoring time point, the corresponding area of ​​each leaf of each crop in each sub-irrigation area at the characteristic monitoring time point, and the corresponding length of each root system of each crop in each sub-irrigation area at the characteristic monitoring time point;

[0029] The above-mentioned characteristic monitoring time points are specifically several characteristic monitoring time points that divide the characteristic monitoring period into time points, where the division method can be 1 hour. The characteristic monitoring period is determined by the irrigation district dispatching personnel based on a comprehensive analysis of factors such as the dispatching status, crop growth status, and actual monitoring needs.

[0030] The above growth data can be specifically extracted from the monitoring report of the crop growth monitoring component.

[0031] The corresponding areas of each leaf of each crop plant in each sub-irrigation area at the characteristic monitoring time point are added together to obtain the total leaf area of ​​each crop plant in each sub-irrigation area at the characteristic monitoring time point.

[0032] The corresponding lengths of the roots of each crop in each sub-irrigation area at the characteristic monitoring time point are added together to obtain the total root length of each crop in each sub-irrigation area at the characteristic monitoring time point.

[0033] The plant height of each crop in each sub-irrigation area at the characteristic monitoring time point, the number of leaves of each crop in each sub-irrigation area at the characteristic monitoring time point, the total chlorophyll content of leaves of each crop in each sub-irrigation area at the characteristic monitoring time point, the total leaf area of ​​each crop in each sub-irrigation area at the characteristic monitoring time point, and the total root length of each crop in each sub-irrigation area at the characteristic monitoring time point are comprehensively analyzed to obtain the growth characteristic evaluation value of the crops in each sub-irrigation area. The specific method is as follows:

[0034]

[0035] In the formula, is the growth characteristic evaluation value of the crops in the g-th sub-irrigation area, g is the number of each sub-irrigation area, , G is the total amount of the sub-irrigation area, is the plant height of the hth crop in the gth sub-irrigation area at the characteristic monitoring time point, h is the number of each crop, , H is the total amount of crops, is the number of leaves of the h-th crop in the g-th sub-irrigation area at the characteristic monitoring time point, is the total chlorophyll content of the leaves of the h-th crop in the g-th sub-irrigation area at the characteristic monitoring time point, is the total leaf area of ​​the h-th crop in the g-th sub-irrigation area at the characteristic monitoring time point, is the total root length of the h-th crop in the g-th sub-irrigation area at the characteristic monitoring time point, is the growth characteristic weight parameter corresponding to the crop height predefined in the irrigation area scheduling information database. is the growth characteristic weight parameter corresponding to the number of leaves predefined in the irrigation area scheduling information database, is the growth characteristic weight parameter corresponding to the total chlorophyll content of leaves predefined in the irrigation area scheduling information database. is the growth characteristic weight parameter corresponding to the total leaf area predefined in the irrigation area scheduling information database. is the growth characteristic weight parameter corresponding to the total root length predefined in the irrigation area scheduling information database, and e is a natural constant.

[0036] It should be explained that the parameters in the above expressions are data of different dimensions and have different units and magnitudes. Therefore, a normalized data processing method is used for the data in the above expressions to eliminate the dimensional differences and weight imbalance problems between different features and improve the convergence speed and accuracy of the above expressions.

[0037] In this embodiment, the growth characteristic evaluation value of the crops in each sub-irrigation area is expressed as a quantitative description of the growth stage of the crops, which helps irrigation area dispatchers to reasonably arrange irrigation activities according to the key period of crop growth. For the growth characteristic evaluation value, the irrigation area dispatching information database stores the growth characteristics corresponding to each growth characteristic evaluation value interval, which reflects the physiological characteristics of the crops.

[0038] It should be explained that the above-mentioned crop height refers to the vertical distance from the base of the crop (usually the ground part) to the top of the crop (such as the highest leaf, ear or stem tip of the plant) of each crop monitored by the crop growth monitoring component at the characteristic monitoring time point; the number of leaves refers to the number of leaves grown on each crop monitored by the crop growth monitoring component at the characteristic monitoring time point; the total chlorophyll content of leaves refers to the total content of chlorophyll in the leaves of each crop monitored by the crop growth monitoring component at the characteristic monitoring time point, and its unit can be milligrams / gram, for example, 1 gram of leaves contains 20 mg of chlorophyll; the total leaf area refers to the total area of ​​the leaves grown on each crop monitored by the crop growth monitoring component at the characteristic monitoring time point; the total root length refers to the total length of the roots growing on each crop monitored by the crop growth monitoring component at the characteristic monitoring time point.

[0039] Among them, the growth characteristic weight parameters corresponding to crop plant height, the growth characteristic weight parameters corresponding to the number of leaves, the growth characteristic weight parameters corresponding to the total chlorophyll content of leaves, the growth characteristic weight parameters corresponding to the total leaf area and the growth characteristic weight parameters corresponding to the total root length are all extracted from the irrigation district scheduling information database, and the mapping relationship can be a one-to-one correspondence or a many-to-one relationship. For example, the crop plant height and the growth characteristic weight parameters corresponding to the crop plant height preset in the irrigation district scheduling information database form a mapping set, and the real-time crop plant height is brought into the mapping set to obtain the growth characteristic weight parameters corresponding to the crop plant height; the leaf number and the growth characteristic weight parameters corresponding to the leaf number preset in the irrigation district scheduling information database form a mapping set, and the real-time leaf number is brought into the mapping set to obtain the growth characteristic weight parameters corresponding to the leaf number; the total chlorophyll content of leaves and the growth characteristic weight parameters corresponding to the total chlorophyll content of leaves preset in the irrigation district scheduling information database The growth characteristic weight parameters of the total leaf area and the preset total leaf area in the irrigation district scheduling information library form a mapping set, and the real-time total leaf area is brought into the mapping set to obtain the growth characteristic weight parameters corresponding to the total leaf area; the total root length and the growth characteristic weight parameters corresponding to the preset total root length in the irrigation district scheduling information library form a mapping set, and the real-time total root length is brought into the mapping set to obtain the growth characteristic weight parameters corresponding to the total root length. In this embodiment, the value ranges of the growth characteristic weight parameters corresponding to the crop plant height, the growth characteristic weight parameters corresponding to the number of leaves, the growth characteristic weight parameters corresponding to the total leaf chlorophyll content, the growth characteristic weight parameters corresponding to the total leaf area, and the growth characteristic weight parameters corresponding to the total root length are all (0, 1).

[0040] In this embodiment, as the height of the crop increases, the number of leaves will generally increase, and the total area of ​​the leaves will also expand accordingly, because during the growth of the crop, the increase in plant height provides space for the growth of the leaves. At the same time, the growth of the leaves also helps the plant to produce more organic matter through photosynthesis, providing energy and material basis for the plant height; a large number of leaves and a large area mean that there is more chlorophyll carrying space. Generally, the larger the total area of ​​the leaves, the higher the total chlorophyll content, because chlorophyll is distributed in the chloroplasts of the leaves, and more leaves can accommodate more chloroplasts, thereby containing more chlorophyll; crops with a longer total root length can absorb more nutrients such as nitrogen, phosphorus, and potassium, promoting the growth of the leaves. The growth and chlorophyll synthesis of crops are indirectly affected by the changes in the number of leaves, the total leaf area and the total chlorophyll content. The comprehensive changes in these parameters can help accurately determine the growth stage of crops. For example, in the early stage of crop growth, the plant height is low, the number of leaves is small, the total leaf area is small, the total chlorophyll content is relatively low, and the total length of the root system is short. At this time, the growth characteristic evaluation value of the crops in each sub-irrigation area is small. With the passage of time, these parameters gradually increase. When the plant height reaches a certain level, the number and area of ​​leaves grow steadily, the total chlorophyll content is maintained at a high level, and the root system is well developed, it means that the crops have entered a vigorous growth period, and the growth characteristic evaluation value of the crops in each sub-irrigation area is at a large value.

[0041] Furthermore, the matching obtains the estimated water demand of the crops in each sub-irrigation area and the estimated irrigation period of the crops in each sub-irrigation area. The specific matching process is:

[0042] The growth characteristic evaluation values ​​of the crops in each sub-irrigation area are matched with the estimated water requirements corresponding to the growth characteristic evaluation value intervals predefined in the irrigation area scheduling information database. The specific matching process is: extracting a mapping set between the growth characteristic evaluation values ​​of the crops in each sub-irrigation area and the estimated water requirements from the irrigation area scheduling information database, determining the interval to which the growth characteristic evaluation values ​​of the crops in each sub-irrigation area belong, and allocating the estimated water requirements of the interval to the crops in each sub-irrigation area corresponding to the growth characteristic evaluation values, so as to match and obtain the estimated water requirements of the crops in each sub-irrigation area.

[0043] The growth characteristic evaluation values ​​of the crops in each sub-irrigation area are matched with the estimated irrigation time periods corresponding to the growth characteristic evaluation value intervals predefined in the irrigation area scheduling information database. The specific matching process is: extracting the mapping set between the growth characteristic evaluation values ​​of the crops in each sub-irrigation area and the estimated irrigation time periods from the irrigation area scheduling information database, determining the interval to which the growth characteristic evaluation values ​​of the crops in each sub-irrigation area belong, and allocating the estimated irrigation time period of the interval to the crops in each sub-irrigation area corresponding to the growth characteristic evaluation value, so as to match and obtain the estimated irrigation time period of the crops in each sub-irrigation area.

[0044] It should be explained that the water demand of the crops in the above-mentioned sub-irrigation areas and the irrigation period of the crops in each sub-irrigation area are affected by a variety of factors, including the physiological characteristics of the crops themselves, soil conditions and meteorological factors. At the same time, these values ​​have a certain reasonable range and will not increase indefinitely. For example, in the rice seedling stage, because it has just been sown or transplanted, the plant height is relatively short, generally around 10-15 cm, the number of leaves is small, usually 3-5 leaves, and the root system is not fully developed. At this time, the growth characteristic evaluation value can be set at 0-30. Assuming the full score is 100, the water demand of rice seedlings is relatively small, because the plants are small, the transpiration and photosynthesis intensity are low, and the estimated water demand per mu per day is about 3-5 cubic meters; during this period, because the seedlings are relatively fragile and sensitive to environmental changes, the irrigation period is best chosen in the morning, such as 7-9 o'clock or in the evening, such as 17-19 o'clock. At this time, the temperature is relatively low and the evaporation is small, which is conducive to the seedlings absorbing water and avoiding damage to the seedlings caused by irrigation during high temperature periods.

[0045] During the booting stage, rice grows vigorously, plant height can reach 70-100 cm, the number of leaves is about 10-12 leaves, and the ear begins to form, the ear gradually develops, the root system is more developed, and the growth characteristic evaluation value is between 60-90. This is the period when rice requires the most water, because the development of the ear requires a lot of water, and photosynthesis and transpiration are also very strong. The estimated water requirement per mu per day can reach about 10-12 cubic meters. In order to ensure the water demand of rice in the booting stage, the irrigation time can be appropriately extended. While irrigating in the morning and evening, if the weather is hot and the evaporation is large, a small amount of water can be added at noon, but care should be taken to avoid large-scale irrigation during high temperature and strong light periods, which may cause damage to the rice due to excessive water temperature.

[0046] Estimated water resource loss: The meteorological data monitoring component monitors the meteorological environment of each sub-irrigation area, collects real-time meteorological characteristic data of each sub-irrigation area during the estimated irrigation period of the crops in each sub-irrigation area, evaluates the impact value of the meteorological characteristics of each sub-irrigation area during the estimated irrigation period, matches the estimated water resource loss of each sub-irrigation area during the estimated irrigation period, and uploads it to the irrigation area water resource scheduling component.

[0047] The above-mentioned meteorological data monitoring component specifically includes a temperature sensor, which can measure the air temperature in real time; a wind speed sensor, which can measure wind direction and wind speed; a light sensor, which is used to monitor light intensity and duration; the meteorological data monitoring component can collect and preliminarily process the meteorological data collected by each sensor, that is, convert the analog signal transmitted by the sensor into a digital signal, and wirelessly communicate with the irrigation area water resource scheduling component.

The specific matching process is: extracting the mapping set between the total chlorophyll content of leaves of each crop in each sub-irrigation area at the characteristic monitoring time point and each sunshine reference intensity from the irrigation area scheduling information database, determining the interval to which the total chlorophyll content of leaves of each crop in each sub-irrigation area belongs at the characteristic monitoring time point, and allocating the sunshine reference intensity corresponding to the interval to each crop in each sub-irrigation area corresponding to the total chlorophyll content of leaves, so as to match the sunshine reference intensity corresponding to each crop in each sub-irrigation area, and performing mean processing to obtain and record it as the mean sunshine reference intensity of each sub-irrigation area.

[0052] The total root length of each crop in each sub-irrigation area at the characteristic monitoring time point is matched with the environmental reference temperature corresponding to each total root length interval predefined in the irrigation area scheduling information database. The specific matching process is: extracting the mapping set between the total root length of each crop in each sub-irrigation area at the characteristic monitoring time point and each environmental reference temperature from the irrigation area scheduling information database, determining the interval to which the total root length of each crop in each sub-irrigation area belongs at the characteristic monitoring time point belongs, and assigning the environmental reference temperature corresponding to the interval to each crop in each sub-irrigation area corresponding to the total root length, so as to match and obtain the mean environmental reference temperature corresponding to each crop in each sub-irrigation area, perform mean processing to obtain and record it as the mean environmental reference temperature of each sub-irrigation area.

[0053] The soil type of each sub-irrigation area is obtained, and matched with the soil characteristic influence coefficient corresponding to each soil type predefined in the irrigation area scheduling information database. The specific matching process is: obtain the mapping set between the soil type of each sub-irrigation area and the soil characteristic influence coefficient from the irrigation area scheduling information database, determine the specific soil category of each sub-irrigation area, and assign the soil characteristic influence coefficient corresponding to the category to each sub-irrigation area corresponding to the soil type, so as to obtain the soil characteristic influence coefficient of each sub-irrigation area.

[0054] The above soil types can be detected by a multi-parameter soil analyzer.

[0055] The real-time sunshine intensity, real-time wind speed, real-time ambient temperature, real-time water vapor evaporation and soil characteristic influence coefficient of each sub-irrigation area during the estimated irrigation period are comprehensively analyzed to obtain the meteorological characteristic influence value of each sub-irrigation area during the estimated irrigation period. The specific analysis method is as follows:

[0056]

[0057] In the formula, is the meteorological characteristic impact value of the g-th sub-irrigation area during the estimated irrigation period, g is the number of each sub-irrigation area, , G is the total amount of the sub-irrigation area, t is the time variable, , To estimate the start time of the irrigation period, To estimate the end time of the irrigation period, is the real-time sunshine intensity of the g-th sub-irrigation area at the t-th moment during the estimated irrigation period, is the mean reference sunshine intensity of the g-th sub-irrigation area, is the real-time ambient temperature of the g-th sub-irrigation area at the t-th moment during the estimated irrigation period, is the mean ambient reference temperature of the g-th sub-irrigation area, is the real-time ambient wind speed of the g-th sub-irrigation area at the t-th moment during the estimated irrigation period, is the real-time water vapor evaporation of the g-th sub-irrigation area at the t-th moment during the estimated irrigation period, is the soil characteristic influence coefficient of the g-th irrigation area, It is the meteorological characteristic parameter corresponding to the real-time ambient wind speed predefined in the irrigation area dispatch information database. It is the meteorological characteristic parameter corresponding to the real-time water vapor evaporation predefined in the irrigation area scheduling information database. It is the meteorological characteristic parameter corresponding to the soil characteristic influence coefficient predefined in the irrigation area scheduling information database, and e is a natural constant.

[0058] It should be explained that the parameters in the above expressions are data of different dimensions and have different units and magnitudes. Therefore, a normalized data processing method is used for the data in the above expressions to eliminate the dimensional differences and weight imbalance problems between different features and improve the convergence speed and accuracy of the above expressions.

[0059] The meteorological characteristic impact value of the above-mentioned sub-irrigation areas during the estimated irrigation period is expressed as a numerical value that comprehensively evaluates the degree of influence of meteorological factors on the irrigation process. It takes into account the comprehensive influence of various meteorological factors such as temperature, wind speed, and light on irrigation demand and irrigation effect during the estimated irrigation period. The larger the meteorological characteristic impact value, the more easily the irrigation quality will be affected during the irrigation process.

[0060] It should be explained that the above-mentioned real-time sunshine intensity refers to the intensity of sunlight actually received by each sub-irrigation area during the estimated irrigation period. The sunshine intensity is usually measured by the solar radiation power received per unit area, and the unit is watt / square meter (W / m²), which reflects the strength of solar radiation; the mean sunshine reference intensity refers to the adaptive mean corresponding to the preset sunshine intensity; the real-time ambient temperature refers to the temperature of the air around each sub-irrigation area actually measured during the estimated irrigation period; the mean ambient reference temperature refers to the adaptive mean corresponding to the preset ambient temperature; the real-time ambient wind speed refers to the wind speed measured during the estimated irrigation period. The real-time water vapor evaporation refers to the amount of water vapor actually evaporated into the atmosphere per unit time from the ground per unit area of ​​each sub-irrigation area, including soil surface, water surface and vegetation surface, during the estimated irrigation period. It is usually expressed in millimeters (mm), which reflects the actual amount of water lost due to evaporation in a specific period of time and in a specific area. The soil characteristic influence coefficient refers to the coefficient of the influence of soil texture characteristics on factors such as irrigation area water scheduling and crop growth. The soil texture characteristics can be specifically sandy soil, loam, clay and other categories.

[0061] The meteorological characteristic parameters corresponding to the real-time ambient wind speed, the meteorological characteristic parameters corresponding to the real-time water vapor evaporation, and the meteorological characteristic parameters corresponding to the soil characteristic influence coefficient are all extracted from the irrigation area scheduling information database, and the mapping relationship can be a one-to-one correspondence or a many-to-one relationship. For example, the real-time ambient wind speed and the meteorological characteristic parameters corresponding to the real-time ambient wind speed preset in the irrigation area scheduling information database form a mapping set, and the real-time ambient wind speed is brought into the mapping set to obtain the meteorological characteristic parameters corresponding to the real-time ambient wind speed; the real-time water vapor evaporation and the meteorological characteristic parameters corresponding to the real-time water vapor evaporation preset in the irrigation area scheduling information database form a mapping set, and the real-time water vapor evaporation is brought into the mapping set to obtain the meteorological characteristic parameters corresponding to the real-time water vapor evaporation; the soil characteristic influence coefficient and the meteorological characteristic parameters corresponding to the soil characteristic influence coefficient preset in the irrigation area scheduling information database form a mapping set, and the real-time soil characteristic influence coefficient is brought into the mapping set to obtain the meteorological characteristic parameters corresponding to the soil characteristic influence coefficient. In this embodiment, the value ranges of the meteorological characteristic parameters corresponding to the real-time ambient wind speed, the meteorological characteristic parameters corresponding to the real-time water vapor evaporation, and the meteorological characteristic parameters corresponding to the soil characteristic influence coefficient are all (0, 1).

[0062] In this embodiment, the sunshine intensity is the main energy source for the increase of ambient temperature. Strong sunshine will make the ground and vegetation absorb solar radiation energy, thereby causing the temperature to rise. If the sunshine intensity is too large and deviates from the sunshine intensity reference value, the ambient temperature will be too high and deviate from its ambient temperature reference value. At the same time, it will also accelerate the evaporation of water vapor in the entire area, greatly increasing the amount of water vapor evaporation, resulting in a large meteorological characteristic impact value of each sub-irrigation area during the estimated irrigation period, which has a negative impact on water resource irrigation and scheduling; the interaction between ambient temperature and wind speed also affects the amount of water vapor evaporation. When the temperature rises, the air density near the ground decreases, forming an updraft, which is easy to produce convection with the surrounding cold air, thereby increasing the wind speed. The increase in wind speed will accelerate the diffusion of water vapor and reduce the concentration of water vapor near the evaporation surface, so that the amount of water vapor evaporation increases, which also leads to an increase in the meteorological characteristic impact value; soil texture determines the water retention capacity and pore structure of the soil in each sub-irrigation area. The larger the soil characteristic impact coefficient, the worse the soil water retention capacity, thereby affecting water vapor evaporation and aggravating the negative impact on water resource irrigation and scheduling.

[0063] Furthermore, the matching obtains the estimated water resource loss of each sub-irrigation area during the estimated irrigation period. The specific matching process is as follows:

[0064] The meteorological characteristic impact value of each sub-irrigation area during the estimated irrigation period is matched with the estimated water resource loss corresponding to each meteorological characteristic impact value interval predefined in the irrigation area scheduling information database. The specific matching process is: obtain the mapping set between the meteorological characteristic impact value of each sub-irrigation area during the estimated irrigation period and the estimated water resource loss from the irrigation area scheduling information database, determine the interval to which the meteorological characteristic impact value of each sub-irrigation area during the estimated irrigation period belongs, and allocate the estimated water resource loss corresponding to the interval to each sub-irrigation area corresponding to the meteorological characteristic impact value, so as to match and obtain the estimated water resource loss of each sub-irrigation area during the estimated irrigation period.

[0065] Irrigation district scheduling status determination: The irrigation district water resource scheduling component monitors the water resources of the irrigation district in real time, collects water supply data of each water transfer channel in the irrigation district during the estimated irrigation period of the crops in each sub-irrigation district, and comprehensively considers the estimated water demand of the crops in each sub-irrigation district and the estimated water resource loss of each sub-irrigation district during the estimated irrigation period. It evaluates the scheduling quality indicators of each water transfer channel in the irrigation district during the estimated irrigation period, and compares them with the predefined scheduling quality reference indicators to determine the scheduling status of each water transfer channel in the irrigation district during the estimated irrigation period, and provide feedback on the irrigation district water scheduling.

[0066] The above-mentioned irrigation area water resource scheduling component is wirelessly connected to the crop growth monitoring component and the meteorological data monitoring component, and specifically includes a flow sensor, which is mainly used to measure the water flow rate and flow rate in water delivery facilities such as channels and pipelines; a valve flow sensor, which is used to measure the flow of water outlet valves in reservoirs, ponds, and other water sources; a valve controller, which is used to control the gate opening of the channel facility, and adjust the gate opening degree by receiving the scheduling instructions of the irrigation area water resource scheduling component, thereby controlling the flow rate and direction of the water flow; the irrigation area water resource scheduling component can collect and preliminarily process the data collected by devices such as flow sensors, valve flow sensors and valve controllers, and convert analog signals into digital signals, so that irrigation area scheduling personnel can grasp the irrigation area water scheduling situation in real time.

[0067] Specifically, the scheduling quality index of each water delivery channel in the irrigation area is evaluated during the estimated irrigation period, and the specific evaluation process is as follows:

[0068] The water supply data of each water transfer channel in the irrigation area specifically include the actual delivery volume of each water transfer channel in the irrigation area during the estimated irrigation period, the actual arrival volume of each water transfer channel in the irrigation area during the estimated irrigation period, and the maximum flow rate of each water transfer channel in the irrigation area during the estimated irrigation period.

[0069] The above water supply data can be specifically extracted from the scheduling report of the irrigation area water resources scheduling component.

[0070] The actual water delivery volume of each water delivery channel in the irrigation area during the estimated irrigation period is subtracted from the actual arrival volume of each water delivery channel in the irrigation area during the estimated irrigation period to obtain and record the actual water resource loss of each water delivery channel in the irrigation area during the estimated irrigation period.

[0071] The real-time environmental wind speed of each sub-irrigation area during the estimated irrigation period is matched with the maximum reference flow rate corresponding to each real-time environmental wind speed interval predefined in the irrigation area scheduling information library. The specific matching process is: obtain the mapping set between the real-time environmental wind speed of each sub-irrigation area during the estimated irrigation period and the maximum reference flow rate from the irrigation area scheduling information library, determine the specific interval of the real-time environmental wind speed of each sub-irrigation area during the estimated irrigation period, and allocate the maximum reference flow rate corresponding to the interval to each sub-irrigation area corresponding to the real-time environmental wind speed, so as to match the maximum reference flow rate of each sub-irrigation area, and obtain the maximum reference flow rate of each water transfer channel in the irrigation area through a preset corresponding method.

[0072] It should be explained that the above preset correspondence method is specifically a one-to-one correspondence between each sub-irrigation area and each water transfer channel in the irrigation area.

[0073] The crop growth monitoring component monitors the growth status of crops in each sub-irrigation area in real time during the estimated irrigation period, collects the growth data of crops in each sub-irrigation area during the estimated irrigation period, determines the growth characteristic evaluation value of crops in each sub-irrigation area during the estimated irrigation period, and obtains and records the growth characteristic evaluation value of crops in the sub-irrigation area of ​​each water transfer channel in the irrigation area during the estimated irrigation period through a preset corresponding method.

[0074] The growth data of the crops in the above-mentioned sub-irrigation areas during the estimated irrigation period specifically include the plant height of each crop in each sub-irrigation area at the estimated irrigation time point, the number of leaves of each crop in each sub-irrigation area at the estimated irrigation time point, the total chlorophyll content of the leaves of each crop in each sub-irrigation area at the estimated irrigation time point, the corresponding area of ​​each leaf of each crop in each sub-irrigation area at the estimated irrigation time point, and the corresponding length of each root system of each crop in each sub-irrigation area at the estimated irrigation time point.

[0075] The above-mentioned estimated irrigation time points are specifically a number of estimated irrigation time points obtained by dividing the estimated irrigation period into time points, wherein the division method may be 1 hour.

[0076] The specific method for determining the growth characteristic evaluation value of the crops in each sub-irrigation area during the estimated irrigation period is shown in the specific method for determining the growth characteristic evaluation value of the crops in each sub-irrigation area, and will not be repeated in this embodiment.

[0077] The water irrigation adaptation difference and water resource loss adaptation difference are extracted from the irrigation district scheduling information database.

[0078] The estimated water demand of the crops in each sub-irrigation area is obtained through a preset corresponding method and recorded as the estimated water demand of the crops in the sub-irrigation area belonging to each water transfer channel of the irrigation area.

[0079] The estimated water resource loss of each sub-irrigation area during the estimated irrigation period is obtained through a preset corresponding method to obtain the estimated water resource loss of each water delivery channel in the irrigation area during the estimated irrigation period.

[0080] The actual arrival amount of each water delivery channel in the irrigation area during the estimated irrigation period, the estimated water demand of crops in the sub-irrigation area to which each water delivery channel belongs, the estimated water resource loss of each water delivery channel in the irrigation area during the estimated irrigation period, the actual water resource loss of each water delivery channel in the irrigation area during the estimated irrigation period, the maximum flow rate of each water delivery channel in the irrigation area during the estimated irrigation period, and the growth characteristic evaluation value of the crops in each sub-irrigation area during the estimated irrigation period are comprehensively analyzed to obtain the scheduling quality index of each water delivery channel in the irrigation area during the estimated irrigation period. The specific method is as follows:

[0081]

[0082] In the formula, is the dispatching quality index of the f-th water delivery channel in the irrigation area during the estimated irrigation period, f is the number of each water delivery channel, , F is the total volume of the water delivery channel, is the actual arrival volume of the f-th water delivery channel in the irrigation area during the estimated irrigation period, is the estimated water demand of crops in the sub-irrigation area of ​​the f-th water delivery channel in the irrigation area, Poor adaptation of water volume for irrigation. is the actual water resource loss of the f-th water delivery channel in the irrigation area during the estimated irrigation period, is the estimated water resource loss of the f-th water delivery channel in the irrigation area during the estimated irrigation period, Poor adaptation to water resource loss, is the maximum flow rate of the f-th water delivery channel in the irrigation area during the estimated irrigation period, is the maximum reference flow rate of the f-th water delivery channel in the irrigation area, is the growth characteristic evaluation value of the crops in the sub-irrigation area of ​​the f-th water delivery channel in the irrigation area during the estimated irrigation period, It is the scheduling quality influencing parameter corresponding to the growth characteristic evaluation value in the estimated irrigation period predefined in the irrigation area scheduling information database, and e is a natural constant.

[0083] The growth characteristic evaluation values ​​of crops in the sub-irrigation areas of each water transfer channel in the above-mentioned irrigation area during the estimated irrigation period are obtained by comprehensively analyzing the crop height of each crop in each sub-irrigation area at the estimated irrigation time point, the number of leaves of each crop in each sub-irrigation area at the estimated irrigation time point, the total chlorophyll content of leaves of each crop in each sub-irrigation area at the estimated irrigation time point, the total leaf area of ​​each crop in each sub-irrigation area at the estimated irrigation time point, and the total root length of each crop in each sub-irrigation area at the estimated irrigation time point, and the growth characteristic evaluation values ​​of crops in the sub-irrigation areas belonging to each water transfer channel in the irrigation area during the estimated irrigation period are obtained and recorded through a preset corresponding method.

[0084] In this embodiment, the scheduling quality index of each water transfer channel in the irrigation area during the estimated irrigation period is expressed as a quantitative evaluation of the water supply reliability, water distribution rationality, water transfer efficiency, etc. of each water transfer channel in the irrigation area during the estimated irrigation period. The larger the scheduling quality index during the estimated irrigation period, the greater the reliability and rationality of each water transfer channel in the irrigation area.

[0085] It should be explained that the above-mentioned actual arrival volume refers to the amount of water that is actually transported to the corresponding irrigation area through each water transfer channel during the estimated irrigation period. This water volume is usually measured in cubic meters (m³). It is the effective water volume that actually reaches the irrigation destination after deducting losses such as channel leakage and evaporation during the channel water transfer process; the estimated water demand refers to the amount of water required for crops in these sub-irrigation areas in a certain period of time, which is estimated in advance based on various factors. This is a predicted value used to plan irrigation water allocation in advance to meet the water needs of crop growth; the water irrigation adaptation difference refers to the reference value corresponding to the pre-set water irrigation difference; the actual water resource loss refers to the amount of water lost by each water transfer channel during the water transfer process due to various reasons during the estimated irrigation period. Specifically, it is the difference between the actual delivery volume and the actual arrival volume. These losses include It includes the reduction of water volume caused by channel leakage, evaporation of water surface, leakage in the water delivery process and other phenomena; the estimated water resource loss refers to the amount of water that may be lost in each water delivery channel due to various reasons during the water delivery process, which is estimated in advance based on multiple factors. This is a predicted value used to plan irrigation water allocation in advance to meet the water demand of crop growth; the water resource loss adaptation difference refers to the reference value corresponding to the pre-set water resource loss difference; the maximum flow rate refers to the maximum speed that the water flow in the water delivery channel can reach during the estimated irrigation period. This speed is the highest flow speed that the water flow instantly reaches during the channel water delivery process, which is affected by many factors such as channel slope, cross-sectional shape, roughness, and upstream and downstream water level difference. It is usually expressed in meters per second (m / s); the maximum reference flow rate refers to the adaptation value corresponding to the pre-set maximum flow rate.

[0086] The scheduling quality influencing parameters corresponding to the growth characteristic evaluation values ​​in the estimated irrigation period are extracted from the irrigation district scheduling information library, and the mapping relationship can be a one-to-one correspondence or a many-to-one relationship. For example, the growth characteristic evaluation values ​​in the estimated irrigation period and the scheduling quality influencing parameters corresponding to the growth characteristic evaluation values ​​in the estimated irrigation period preset in the irrigation district scheduling information library form a mapping set, and the real-time growth characteristic evaluation values ​​in the estimated irrigation period are brought into the mapping set to obtain the scheduling quality influencing parameters corresponding to the growth characteristic evaluation values ​​in the estimated irrigation period. In this embodiment, the value range of the scheduling quality influencing parameters corresponding to the growth characteristic evaluation values ​​in the estimated irrigation period is (0, 1).

[0087] In this embodiment, the change of the water resource loss difference will directly affect the water irrigation difference. For example, if the water resource loss difference is positive, that is, the actual water resource loss exceeds expectations, then the amount of water reaching the irrigation area will be reduced, resulting in the water irrigation difference being negative, that is, the actual irrigation water volume is less than the water requirement of the crop. Unfavorable changes in the water irrigation difference and the water resource loss difference will have a negative impact on the irrigation effect. If the water irrigation difference is too large, some crops may not get enough water, affecting their growth. If the water resource loss difference is too large, not only will water resources be wasted, but the operating cost of the irrigation system may also increase, and it is also impossible to ensure that there is enough water for irrigation. Irrigation, so that the scheduling quality indicators of each water transfer channel in the irrigation area during the estimated irrigation period are greatly reduced; the maximum flow rate will affect the water transfer capacity and irrigation efficiency of the water transfer channel. During the estimated irrigation period, a higher maximum flow rate can transport water to the irrigation area faster. If the maximum flow rate can be kept within a reasonable range, it will help to reduce the water irrigation difference. On the contrary, the water irrigation difference will also have a feedback effect on the maximum flow rate. If the actual irrigation water volume is greater than the water demand of the crop, it may cause the actual water transfer capacity of the channel to exceed expectations. This is related to the excessively high maximum flow rate, making it difficult to ensure reasonable irrigation water distribution, which has a negative impact on the scheduling quality.

[0088] In this embodiment, if the growth characteristic evaluation value of the crops in the sub-irrigation areas belonging to each water transfer channel in the irrigation area during the estimated irrigation period is larger than the growth characteristic evaluation value of the crops in each sub-irrigation area, it means that the scheduling quality during the estimated irrigation period is high, for example, the crop plant height grows normally, the number and color of leaves meet the requirements of the growth stage, the root system is well developed, etc., which means that the water supply is relatively stable and reliable. A good growth state means that during the estimated irrigation period, the water supply guarantee rate of the water transfer channel is high, and water can be stably supplied according to the growth needs of crops; the growth characteristic evaluation value during the estimated irrigation period can reflect the uniformity of water distribution. If the growth conditions of crops in each sub-irrigation area are relatively consistent, such as uniform plant height and similar degree of leaf luxuriance, this indicates that the water distributed to each sub-irrigation area by the water transfer channel is relatively uniform, and the water distribution uniformity index is better.

[0089] Furthermore, the scheduling status of each water delivery channel in the irrigation area during the estimated irrigation period is determined by the following specific determination process:

[0090] The scheduling quality index of each water transmission channel in the irrigation area during the estimated irrigation period is compared with the scheduling quality reference indexes predefined in the irrigation area scheduling information database. If the scheduling quality index of a water transmission channel in the irrigation area during the estimated irrigation period is greater than or equal to the scheduling quality reference index, the scheduling state of the water transmission channel in the irrigation area during the estimated irrigation period is determined to be a normal scheduling state. If the scheduling quality index of a water transmission channel in the irrigation area during the estimated irrigation period is less than the scheduling quality reference index, the scheduling state of the water transmission channel in the irrigation area during the estimated irrigation period is determined to be an abnormal scheduling state, and feedback is given to the abnormal scheduling state.

[0091] Specifically, the feedback on the water volume scheduling of the irrigation area is specifically feedback that the scheduling state of the water delivery channel in the irrigation area during the estimated irrigation period is an abnormal scheduling state.

[0092] The abnormal scheduling state is fed back, specifically, a scheduling optimization operation is performed on the water delivery channel of the irrigation area, thereby completing the feedback of the water delivery channel of the irrigation area.

[0093] The above-mentioned scheduling optimization operation can be specifically that when it is found that the water transfer channel is in an abnormal scheduling state (for example, the actual arrival amount deviates too much from the estimated water demand), real-time flow data can be obtained through flow sensors and other equipment, and then the gate control system on the channel is used to adjust the gate opening to change the water transfer flow. For example, if the actual arrival amount is far lower than the estimated irrigation amount, the gate opening can be appropriately increased under the condition of sufficient water supply to increase the water transfer flow and ensure that there is enough water to be delivered to each sub-irrigation area; the water transfer time is optimized by considering the impact of meteorological factors on water transfer losses. If, during the estimated irrigation period, the meteorological data monitoring component shows that the wind speed is high and the evaporation is strong in a certain period of time, the water transfer time can be adjusted to a period with less evaporation loss. For example, the water transfer time during the high temperature period during the day can be adjusted to night time to reduce water loss caused by evaporation of the water surface; when it is found that the water loss is abnormally high, it may be a leakage problem in the channel. Inspect the channel and use lining repair methods for leaking parts. For example, for tiny cracks in concrete lined channels, cement mortar can be used for grouting. For leaking areas in earthen channels, soil compaction or laying of anti-seepage geomembranes can be used to reduce leakage.
