[0031] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined invention purpose, the specific implementation, structure, features and effects of the agricultural cultivation water source scheduling method based on data processing according to the present application are described in detail as follows by combining with the drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.
[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.
[0033] The specific scheme of the agricultural cultivation water source scheduling method based on data processing provided by the present application is described in detail below in combination with the drawings.
[0034] An embodiment of the present application provides an agricultural cultivation water source scheduling method based on data processing.
[0035] Specifically, the present application provides an agricultural cultivation water source scheduling method based on data processing, which comprises the following steps: Figure 1
[0036] In step S001, the environment data of each farmland needing water supply is obtained.
[0037] The environment temperature data of each farmland is obtained by a temperature sensor, the air relative humidity data and soil humidity data of each farmland are obtained by a humidity sensor, and the land surface water depth data of each farmland is obtained by a water surface height sensor.
[0038] In step S002, the pheromone evaporation coefficient of each water supply path at each time point is obtained according to the environment data of each farmland at each time point.
[0039] In the farmlands needing water supply, the water demand of different farmlands is different, the water demand of some farmlands is relatively large and the situation is relatively urgent, so the water supply should be given priority to; the water demand of some farmlands is relatively small and the situation is relatively relaxed, so the water supply can be appropriately delayed. However, in the traditional ant colony algorithm, the pheromone evaporation coefficients of different paths are the same, and the water supply path selection does not consider the water supply demand of the farmland, and the water supply demand of the farmland changes with time. Therefore, the pheromone evaporation coefficient of each water supply path at each time point is obtained according to the water supply demand of each farmland at each time point, so as to update and optimize the path in real time, so that the farmland with high water supply demand at each time point can be supplied with water as soon as possible. The specific steps are as follows:
[0040] Generally, the higher the farmland environment temperature and the lower the air relative humidity, the faster the water evaporation speed, the more serious the water loss of the farmland crops and soil, and the higher the farmland water demand; on the contrary, when the temperature is low or the air relative humidity is high, the water evaporation is difficult and the water evaporation speed is slow, and the farmland water demand is relatively low; although the atmospheric pressure also affects the water evaporation speed, the atmospheric pressure of each farmland is relatively stable and is normal atmospheric pressure, so the influence of pressure is not considered. Therefore, taking the jth farmland at the t time point as an example, the water evaporation potential of each farmland at each time point is:
[0041] E j (t)=β·m j (t)·(T+273)
[0042] In the formula, E j (t) is the water evaporation potential of the jth farmland at the t time point, β is a limiting factor, m j (t) is the relative humidity of the air of the jth farmland at the t time point, and T is the environmental temperature of the jth farmland at the t time point. Wherein T is the temperature in Celsius, and the unit is ℃, and T+273 is the corresponding temperature in Kelvin, and the unit is Kelvin.
[0043] It should be noted that the value of β can be set by the implementer, and in this embodiment, the value of β is set to 0.5. Through the setting of β, the value range of water evaporation potential is limited in the range of (0-1], so as to facilitate subsequent calculation; the higher the water evaporation potential, the faster the water evaporation speed in the farmland, and the higher the demand degree of the farmland for water; the lower the water evaporation potential, the slower the water evaporation speed in the farmland, and the lower the demand degree of the farmland for water.
[0044] In common crops, some crops (such as rice) need to accumulate water on the surface of the soil and the accumulated water depth reaches a certain value to grow normally. For example, when the accumulated water depth on the surface of the soil is less than the optimal accumulated water depth required for the growth of rice, the water supply required by the rice is insufficient, which will affect the yield of the rice, so at this time, the demand degree of the rice for water is higher, and the demand degree of the paddy field for water is higher; when the accumulated water depth on the surface of the soil is greater than the optimal accumulated water depth required for the growth of rice, it indicates that the water in the paddy field is already saturated, and no additional water is needed, so at this time, the demand degree of the paddy field for water is lower. In addition, each crop has a certain requirement for soil humidity, when the soil humidity is less than the optimal soil humidity required for the growth of crops, it will affect the absorption of water by crops, affect the normal growth of crops, and thus affect the yield of crops, so at this time, the demand degree of the farmland for water is higher, and the smaller the soil humidity, the drier the land, and the higher the demand degree of the farmland for water; when the soil humidity is greater than the optimal soil humidity required for the growth of crops, the demand degree of the farmland for water is lower. Therefore, taking the jth farmland at the t time point as an example, the crop development water deficiency index of each farmland at each time point is obtained according to the accumulated water depth and the soil humidity of each farmland at each time point, and the expression is:
[0045]
[0046] In the formula, G j (t) is the crop development water deficiency index of the jth farmland at the t time point, WHR j (t) is the relative accumulated water depth of the jth farmland at the t time point, WCR j (t) is the relative soil humidity of the jth farmland at the t time point, e () is the exponential function with e as the base, and α is the limiting factor; h j (t) is the accumulated water depth of the jth farmland at the t time point, h j (0) is the optimal accumulated water depth of the jth farmland at the t time point; c j (t) is the soil humidity of the jth farmland at the t time point, c j(0) is the optimum soil moisture of the jth farmland at time t. It should be noted that the value of α can be set by the implementer. In this embodiment, the value of α is set to 1-e -1 By setting α, the crop development water shortage index is limited to the range of (0,1] to facilitate subsequent calculations; when the jth farmland needs surface water at time t, WHR j The smaller the value of (t), the greater the demand for water for the farmland. When supplying water, the farmland should be given priority as much as possible. j The larger the (t) value is, the smaller the demand for water for the farmland is, and the water supply to the farmland can be appropriately delayed. When the jth farmland does not need surface water at time t, the WHR j The value of (t) is set to -1, so that when calculating the crop development water shortage index, The result is 1, which avoids the lack of water depth parameters in the farmland, thus affecting the calculation of the crop development water shortage index. j The smaller the value of (t), the drier the soil, and the greater the water demand of the jth farmland at time t; j The larger the value of (t), the smaller the water demand of the farmland. j (t) is the crop development water shortage index of the jth farmland at time t, G j The larger the value of (t), the greater the water demand of the farmland, and the higher the priority of water supply to the farmland should be; j The smaller the value of (t), the smaller the water demand of the farmland, and the water supply priority of the farmland should be relatively lowered.
[0047] The rainfall intensity of each farmland at each time point is obtained based on the rainfall observation system. The specific method is well-known technology and will not be elaborated here. Since rainfall provides additional water supply to farmland, taking the jth farmland at time point t as an example, the relative water use comparative advantage of each farmland at each time point is calculated based on the above two indicators combined with rainfall intensity:
[0048]
[0049] Where, CAW j (t) is the comparative advantage of water use of the jth farmland at time t, E j (t) is the water evaporation potential of the jth farmland at time t, G j (t) is the crop development water shortage index of the jth farmland at time t, R j (t) is the rainfall intensity of the j-th farmland at time point t, exp() is an exponential function with e as the base, and γ is a constant to prevent the denominator from being 0. The value of γ can be selected by the implementer. In this embodiment, the value of γ is set to 1.
[0050] When there is rainfall in the area where the j-th farmland is located at time point t, the amount of water required to be transported by the water supply center will decrease, so the water supply order of the farmland can be appropriately delayed; when there is no rainfall in the farmland at time point t, all the water used for the farmland comes from the water supply center. At this time, the water supply demand level of the farmland remains unchanged, and the water supply order cannot be delayed.
[0051] If the relative water use comparative advantage of a certain farmland is greater, it means that when supplying water, the water supply priority of this farmland is higher, and the water supply path should pass through this farmland first, that is, the pheromone volatility coefficient on the water supply path from other farmlands to this farmland should be smaller, so that more pheromones are retained on the water supply path, thereby increasing the probability of ants choosing the path of this farmland; if the relative water use comparative advantage index value of a certain farmland is smaller, then when supplying water, the water supply to this farmland can be appropriately delayed, that is, the pheromone volatility coefficient on the path from other farmlands to this farmland should be larger, so that less pheromones are retained on the water supply path, thereby reducing the probability of ants choosing the path of this farmland.
[0052] Take the jth farmland as an example, Figure 2 As shown, the big dots are water supply centers, the small dots are farmlands, and the straight lines are water supply paths in the irrigation system. Since there is not a direct water supply path between any two farmlands, the farmlands directly connected to farmland j are farmlands 5, 7, 8, and 9. Therefore, the set of other farmlands directly connected to farmland j through the water supply path is allowed. j ={5,7,8,9}, set allowed j As the set of neighboring farmlands of the jth farmland, the pheromone volatility coefficient on each water supply path is constructed, and the expression is:
[0053]
[0054] Where, ρ ij (t) is the volatility coefficient on the water supply path between the i-th farmland and the j-th farmland, CAW j (t) is the comparative advantage of water use of the jth farmland at time t, allowed j is the set of neighboring farmlands of the jth farmland.
[0055] The greater the relative water use comparative advantage of the j-th farmland, the greater the demand for water in the region, and the more pheromones should be retained on the path from other farmlands to the j-th farmland, that is, the pheromone volatility coefficient on the water supply path connected to the j-th farmland is smaller; the smaller the relative water use comparative advantage of the j-th farmland, the smaller the demand for water in the region, and the fewer pheromones should be retained on the path from other farmlands to the j-th farmland, that is, the pheromone volatility coefficient on the water supply path connected to the j-th farmland is larger.
[0056] In step S003, the real-time optimized path of the farmland water supply is obtained through the ant colony algorithm, and the real-time optimized path is sent to the water supply center to complete the reasonable allocation of water resources.
[0057] The evaporation coefficients of the water supply paths are determined through the above steps, and the evaporation coefficients of the water supply paths are taken as pheromone evaporation factors in the ant colony algorithm, and are input into a probability calculation formula of the ant colony algorithm to calculate the probability of water flow through each path from the water supply center, wherein the probability calculation is a known technology, and will not be described here again. The probabilities of the water supply paths are substituted into the ant colony algorithm for modeling, and finally an optimized path for supplying water to each farmland is obtained. The monitoring center of the local agricultural water conservancy department sends the obtained optimized path of farmland water supply to the water supply center, and the water supply center supplies water resources to each farmland according to the optimized path to ensure the normal operation of agricultural production.
[0058] In summary, the embodiment of the present application obtains the optimized path of farmland water supply by combining the data processing technology with the environmental characteristics of the farmland, and realizes the reasonable scheduling of water resources in farmland irrigation according to the optimized path. The evaporation coefficients of the water supply paths are obtained through self-adaptation, which solves the problem of slow convergence speed caused by a single evaporation coefficient in the traditional ant colony algorithm, increases the probability of the water supply route passing through the farmland with high irrigation demand, increases the accuracy of the water supply optimized path, and further improves the timeliness of farmland irrigation.
[0059] In order to solve the problem that a single evaporation coefficient cannot combine the irrigation demand of each farmland, the embodiment combines the environmental factors of each farmland to obtain the relative water use comparative advantage degree of each farmland at each time point, so as to obtain the evaporation coefficients of each water supply path, obtain the water supply optimized path according to the evaporation coefficients, and complete the intelligent irrigation of the farmland according to the water supply optimized path, which has high rationality of farmland water resource scheduling.
