s200: obtaining environmental information of the first crop within the first greenhouse;
specifically, the facility crops include: facility planting, such as greenhouse vegetables, fruits, and the like; facility farming, such as animal farming; culturing edible fungi such as lactobacillus. Different facility crops have different dependence on growth environment, and in conclusion, in order to guarantee the growth environment elements of the crops: information such as temperature, humidity, oxygen concentration, carbon dioxide concentration, pH, salinity, illumination, etc. is fully controllable, and a large walk-in phytotron is generally used as the growing environment of crops.

By timely adjusting the environmental information in the first greenhouse, the occurrence of difference information between the first prediction result and the expected growth condition information is avoided, and the technical effect of guaranteeing the growth state of the first crop in advance is achieved.
S700: according to the first adjusting instruction, a standard matching degree training set of the environmental information in the first greenhouse and a crop variety training set is obtained;
specifically, the crop variety training set refers to a variety of crop variety information cultivated in the first greenhouse, illustratively: apple, orange, grape and other varieties cultivated in large-scale walk-in artificial climates; the standard matching degree training set refers to the difference degree information obtained by matching the optimal environmental information in the first greenhouse in the growth states of different crop varieties and comparing the optimal environmental information with the current environmental information, and the difference degree information is exemplarily shown as follows: if the controllable environmental elements of the large-scale walk-in artificial climate chamber comprise information such as temperature, illumination, pH value and humidity, the specific values of the information such as the temperature, the illumination, the pH value and the humidity of the three groups of the apples, the oranges and the grapes are corresponding to the same time node; and the same crop variety also corresponds to a plurality of groups of specific values of temperature, illumination, pH value, humidity and other information at different time nodes, and the matched environmental element information and the real-time environmental information are compared to obtain a standard matching degree training set.

Further, adjusting the environment information is, for example, preferable: adjusting environmental indexes of grape crops: adjusting illumination information: a = [ illumination information, illumination intensity, illumination duration, etc. ]; adjusting temperature information: b = [ temperature information, temperature value ]; adjusting humidity information: c = [ humidity information, water content adjustment value ], and the like. The environmental information of the first greenhouse is adaptively adjusted by adjusting the environmental information, so that the growth state of the first crop is ensured to reach an expected growth state.

Further, after the inputting the crop variety information of the first crop and the standard matching degree of the first crop into the environment control model, the step S900 further includes:
s910: constructing and training an identification network according to the standard matching degree training set and the crop variety training set and the generation data of the environment control model;
s920: obtaining the accuracy of the output data of the environment control model based on the identification network;
s930: and screening the output data of the environment control model according to the accuracy.

s1023: and calculating according to the elevation angle of the rear roof, the intersection angle of the front roof and the ground and the length of the rear slope to obtain the light entering amount.
Specifically, in general, the greenhouse structure is set as a single-roof greenhouse, so that the illumination quantity can be adjusted conveniently, and aiming at the single-roof greenhouse: in order to ensure sufficient irradiation of sunlight, an inclined roof in the east-west direction is generally adopted; the elevation angle of the rear roof refers to the lifting angle of the sloping roof close to the west side relative to the ground, and the intersection angle of the front roof and the ground refers to the intersection angle of the sloping roof close to the east side relative to the ground; the back slope length refers to the roof length information of the back roof and the front roof. The light advance duration in the preset time in unit area can be determined through the elevation angle of the rear roof, the intersection angle of the front roof and the ground and the length of the rear slope, and the light advance duration is recorded as the light advance amount, so that the feedback processing of the backward step information is facilitated.
Further, as shown in fig. 3, based on the obtaining of the light entering intensity according to the light-transmitting material, the step S1040 includes:
s1041: obtaining the illumination attenuation intensity of the light-transmitting material according to the light-transmitting material;
s1042: obtaining real-time illumination intensity;

Specifically, the first anti-fouling rating refers to information characterizing the fouling retention capacity of the light-transmitting material, and is determined by an exemplary method: collecting the dirt remaining area of the light-transmitting material in the same environment within a preset time period, wherein the larger the area is, the higher the first dirt-resisting grade of the light-transmitting material is; the smaller the area, the lower the first anti-fouling grade of the light-transmitting material.
When the first anti-fouling grade meets the preset grade, the preset time period dirt retention area is indicated to have influence on light transmission, and the first cleaning period is required to be set for cleaning the first greenhouse, wherein the first cleaning period is less than or equal to one half of the preset time period. Thereby ensuring the performability of the environment adjustment information and the healthy growth of the first crop.
