Description
Technical Field
The invention belongs to the technical field of intelligent crop management, and particularly relates to an illumination management system for a field crop in a full growth period.
Background
With advances in science and technology and the intensive research on photosynthesis, field crop light management has become increasingly feasible; because of the varying intensity of sunlight, the photosynthetic efficiency of various crops also varies over the course of a day. When the light intensity exceeds the light saturation point of the crop, the photosynthesis efficiency gradually decreases, and at noon 11:00 to 14: in the 00 time period, the light intensity far exceeds the light saturation point of most crops, the crops are in a light inhibition state, and the phenomenon of photosynthesis 'noon break' occurs; if the illumination intensity can be regulated and controlled according to the photosynthesis efficiency, the crop yield and quality are expected to be greatly improved; and redundant illumination is used for photovoltaic power generation, so that the economic benefit of unit land can be greatly improved.
Regarding compatible crop planting of photovoltaic power generation, the development of the photovoltaic industry is rapid in the last decade, the installation of the photovoltaic needs to occupy a lot of space, the combination of the photovoltaic and the agriculture is more and more emphasized, the return on investment on the unit occupied area of the photovoltaic is higher than that of the agriculture, photovoltaic enterprises usually pay more attention to the photovoltaic benefits in the earlier stage, more sunlight is used for power generation, the sunlight for plant growth is usually placed in secondary positions or ignored, the plant can not grow normally, and therefore the benefit of the combination of the photovoltaic industry and the agriculture is not high.
At present, more than 95% of photovoltaic sheets in the photovoltaic industry are based on crystalline silicon components, and the crystalline silicon components are combined with agriculture, so that the photovoltaic sheets have application cases. Some plants are directly paved on the ground in the early stage, and the growth of the plants is seriously influenced; some of the stray light is erected on the ground for more than 2 meters, so that more stray light irradiates the ground; some hollow photovoltaic panels form a mosaic array; some of the light sources are added with a light homogenizing plate to form a light homogenizing environment with low illumination. Different schemes, the illumination proportion of crops under the photovoltaic panel is gradually improved. However, the above solution has the following problems in practical application: after the photovoltaic panel is installed, the illumination is basically relatively fixed, and the illumination is not adjustable. On the same piece of land, the illumination conditions are different for continuous sunny days and rainy days; the illumination requirements are different for crops of different crops in the same land in different seasons; the illumination intensity needs to be adjusted for different growth stages of crops; for example, wheat shows a trend of increasing, decreasing, increasing and decreasing in the jointing period Pn, generally 9-11; while the flowering phase shows a unimodal trend of increasing first and then decreasing. In the prior art, the illumination can not be adjusted every day, the maximum illumination intensity is relatively fixed after the photovoltaic is additionally arranged, and the yield and the quality can be seriously influenced if the illumination intensity is not increased for a period of time in which strong illumination is particularly needed for certain specific crops in one year.

As a further optimization scheme of the invention, when first control data is received, the output module outputs a command for adjusting the photovoltaic panel and the wind direction to be parallel to the tracking photovoltaic system; when second control data are received, the output module outputs a command for adjusting the photovoltaic panel to be vertical to the ground to the tracking type photovoltaic system; when third control data are received, the output module outputs a command for adjusting the photovoltaic panel and the sunlight to be parallel to the tracking type photovoltaic system; and when the fourth control data is received, the output module outputs a command for adjusting the photovoltaic panel and the sunlight to be vertical to the tracking type photovoltaic system.
As a further optimization scheme of the invention, the tracking type photovoltaic system comprises a plurality of groups of tracking photovoltaic panel units which are built above a farmland through a support frame and are distributed linearly, wherein each tracking photovoltaic panel unit comprises a support frame, a photovoltaic panel, a light homogenizing panel and a driving motor, the photovoltaic panel, the light homogenizing panel and the driving motor are positioned on the support frame, the driving motor drives the support frame to rotate, a group of light homogenizing panels is embedded between every two groups of photovoltaic panels, the driving motor is controlled by an output module in the intelligent controller, and the total area ratio of the light homogenizing panel and the photovoltaic panel in the tracking type photovoltaic system is 1.

The invention has the beneficial effects that:
1) According to the invention, under the condition that the crop yield is not influenced, the illumination management system can averagely improve 10% of generated energy, and acquires illumination data required by different planting modes, different plants and different growth periods through the sensor system, establishes the database and the algorithm model, and intelligently adjusts the angle of the dodging photovoltaic plate according to the collected illumination data in combination with weather parameters, compared with the traditional agricultural photovoltaic application, the method can control the illumination condition under the dodging photovoltaic plate, can adjust the photovoltaic plate to be parallel to sunlight when the plants need strong illumination so as to provide sufficient illumination for the plants to grow, and can adjust the photovoltaic plate to vertically shield the sunlight with the sunlight to reduce the illumination intensity and generate electricity when the illumination is too strong to inhibit the growth of the plants;
2) According to the invention, the uniform light plate with a certain proportion is added into the photovoltaic plate, the area of the uniform light plate accounts for about 1/2 of the area of the traditional photovoltaic plate, the area of the photovoltaic plate is not reduced, meanwhile, the area of the uniform light plate is added with 1/3 of the area of the uniform light plate, the cost of the uniform light plate is only 1/10 of the cost of the photovoltaic plate, so that the cost of the whole system is not increased much, but a high-standard uniform light environment with low illumination and uniform illumination can be formed below the photovoltaic plate, and compared with the situations of over-low illumination intensity caused by direct shielding, light intensity jump caused by mosaic uniform light and the like, the growth of plants is facilitated, especially the normal growth and growth of low-illumination plants;
3) The illumination management system has very good adaptability and superiority under extreme weather conditions. When the weather is continuous high-temperature weather and dry weather, the photovoltaic panel can be used for shielding sunlight, so that the temperature of the surface of crops is reduced, and the water evaporation is reduced. When rainfall occurs, particularly heavy rain, water can be collected and left by the fixed photovoltaic panels, the water yield of the photovoltaic panels is insufficient, small water pits can be smashed below the lowest edges of the photovoltaic panels, and irrigation and plant growth are not facilitated. At the moment, whether the angle from the photovoltaic panel to the ground is adjusted or not can be judged according to comprehensive information such as weather forecast and the like, so that rainwater can be uniformly scattered on the ground. In the case of windy weather, the problem of wind sheltering needs to be considered because the areas of the light-homogenizing plate and the photovoltaic plate are large. However, after the tracking design is adopted, a wind shielding mode can be designed, and when the wind power exceeds a certain degree, the photovoltaic panel is adjusted to be parallel to the wind direction, so that the damage and the damage to facilities caused by the gust wind are greatly reduced.

Example 1
As shown in FIGS. 1-10, a system for managing illumination of a field crop during a full growth cycle comprises
The meteorological station is used for collecting meteorological data in real time, wherein the meteorological data comprises PPFD data, temperature data, humidity data, wind power data, rainfall data and atmospheric pressure data;

the meteorological data control model comprises a control model under the preset wind power size, rainwater size and illumination intensity factor modes, and control data based on photovoltaic panel angle adjustment under the wind power size, the rainwater size and the illumination intensity are formed.
Specifically, the meteorological station comprises a PAR measuring instrument for collecting PPFD data in real time, a rainfall and humidity sensor for collecting a real-time temperature thermometer, collecting and judging humidity and precipitation intensity in air, a wind power and wind direction sensor for judging the level number and the wind direction of wind power and an atmospheric pressure sensor.
Specifically, the method comprises the steps of inputting meteorological data into a pre-stored meteorological data control model for matching, outputting first control data of photovoltaic panel angle adjustment if a wind power value in the meteorological data is larger than a first preset value, otherwise, judging whether a rainwater value in the meteorological data is larger than a second preset value, outputting second control data of photovoltaic panel angle adjustment if the rainwater value in the meteorological data is larger than the second preset value, otherwise, comparing PPFD data in the meteorological data with a standard database, outputting third control data of photovoltaic panel angle adjustment if the PPFD value is smaller than a PPFD value for inhibiting photosynthesis in the standard database, and outputting fourth control data of photovoltaic panel angle adjustment if the PPFD value is larger than the PPFD value for inhibiting photosynthesis in the standard database.
Specifically, when first control data are received, the output module outputs a command for adjusting the parallelism of the photovoltaic panel and the wind direction to the tracking photovoltaic system; when second control data are received, the output module outputs a command for adjusting the photovoltaic panel to be vertical to the ground to the tracking type photovoltaic system; when third control data are received, the output module outputs a command for adjusting the photovoltaic panel and the sunlight to be parallel to the tracking photovoltaic system; when the fourth control data is received, the output module outputs a command for adjusting the vertical direction of the photovoltaic panel and the sunlight to the tracking photovoltaic system.
Specifically, pursuit formula photovoltaic system includes the pursuit photovoltaic board unit through the support frame construction in the linear distribution of a plurality of groups of farmland top, and the pursuit photovoltaic board unit includes the carriage and is located the photovoltaic board on the carriage and even light board and drive carriage pivoted driving motor, wherein, inlays a set of even worn-out fur in the middle of per two sets of photovoltaic boards, and driving motor is output module control in by the intelligent control ware, and even worn-out fur is 1 with photovoltaic board total area proportion among the pursuit formula photovoltaic system.
Specifically, the carriage is single-axis structure or biax structure with adjustable angle, and wherein, single-axis structure carriage rotates in order to track the sunlight azimuth under the driving motor effect, and the biax structure carriage is driven by two pivots and the driving motor who corresponds thereof, and one of them pivot drives the carriage and rotates in order to track the azimuth of sunlight under the driving motor effect, and wherein another pivot drives the carriage and rotates in order to track the altitude angle of sunlight under driving motor's effect.
Specifically, the backlight surface of the light homogenizing plate is in a Fresnel lens shape.
It should be noted that in the process of establishing the database, a plurality of experimental fields need to be established to ensure that the samples have good contrast, the experimental fields need to be separated by a certain distance and even be located in different cities to fully ensure the difference of illumination environments, or planting experiments are performed by utilizing the advantage of convenient control variables of plant factories, and the comprehensive illumination information corresponding to the highest yield is selected as the standard database according to the yield of the final crops. The database already contains complete data of plant species, planting area, planting manner, and the like. The standard database is used as a preset value to be embedded into the intelligent controller to become the basis of algorithm decision, and the inclination angle of the photovoltaic panel is further reasonably controlled.
In addition, the photovoltaic panel employs any one of uniaxial tracking and biaxial tracking; the system is characterized in that a light homogenizing plate is added into a photovoltaic plate used in the system, the plate surface is divided into three parts, the light homogenizing plate is placed in the middle, the photovoltaic plates are placed on two sides of the light homogenizing plate (see figures 7 and 8), the total area ratio of the light homogenizing plate to the photovoltaic plates can be flexibly adjusted according to regions, planted crops and the like, and in some embodiments, the area ratio of 1. The light homogenizing plate is a light homogenizing glass plate designed based on the Fresnel lens principle, so that a high-standard illumination environment with low illumination but uniform illumination is formed under the photovoltaic plate.
The decision algorithm mainly aims to compare real-time weather data obtained by a weather station with a standard database preset in an intelligent controller, and output an angle to be adjusted of a photovoltaic panel, so that the controller sends a corresponding instruction to control a motor to rotate to adjust the photovoltaic panel. And in the logic of judgment, whether the wind power is too large or not is judged preferentially according to the data transmitted by the meteorological station. If the wind power is too large, if the wind power exceeds 6 levels, the algorithm drives the intelligent controller and the motor according to the wind direction data in consideration of protecting the facilities, the angle of the photovoltaic panel is adjusted to be parallel to the wind direction, and damage to the facilities is avoided. If the wind power does not exceed 6 levels, the rainfall is judged, namely the rainfall intensity. If the rainfall intensity reaches the middle rain, the angle of the photovoltaic panel is adjusted to be vertical to the ground, so that raindrops can fall uniformly to be prevented from being gathered to the edge of the photovoltaic panel to pound out a water pit on the ground, and the problem of non-uniform rainwater for plant growth is solved. If the precipitation intensity is less than the moderate rain, the value of PPFD (PPFD represents the number of light quanta in the visible wavelength range per unit time area) is determined. If the real-time PPFD value is less than the photosynthesis-inhibiting PPFD value in the predetermined database, the photovoltaic panel is adjusted to be parallel to the sunlight (see fig. 4 and 5), so that the sunlight is fully illuminated. If the sunlight is good and the PPFD value exceeds the preset PPFD value for inhibiting photosynthesis, the photovoltaic panel is adjusted to be perpendicular to the sunlight (see FIG. 6), the sunlight is shielded, and a high-standard uniform light environment is formed below the photovoltaic panel by means of the addition of the uniform light panel. The logic of the algorithm decision is shown in fig. 10.
In the implementation, if the cost needs to be strictly controlled, a tracking manner of a slant single axis can be adopted, see fig. 7. The top of the bracket forms a certain angle with the vertical direction, and the influence of the annual solar altitude angle change on the power generation efficiency is minimum under the angle; the photovoltaic board is equipped with motor drive pivot with the leg joint department, can make photovoltaic board east and west direction track the sunlight and the angle of dynamic adjustment photovoltaic board. To achieve better effects and functions, the advantage of the system needs to be achieved by adopting a two-axis tracking structure, as shown in fig. 7. The upper part of the bracket is provided with a rotating shaft driven by a motor, so that the azimuth angle of the sun can be tracked; the junction of photovoltaic board and support also is equipped with motor drive pivot, can track the solar altitude angle. The following examples all employ a two-axis tracking system.
The illumination management method is applied to wheat planting:
firstly, planting the same kind of wheat in the same way in experimental fields in different places (different illumination as much as possible and similar other conditions), and collecting and recording illumination information, photosynthesis rate information and the like of the wheat in different growth periods by utilizing sensor systems such as a PAR measuring instrument, a photosynthesis rate detection device and the like. And comparing the yields of different experimental fields, taking the whole-process illumination information and photosynthesis inhibition information of the experimental field with the highest yield as a standard database, and then taking the database as preset information to be embedded into the intelligent controller.
Second, the lighting management system is deployed in the field where the wheat is to be planted. The system comprises sensor components such as a PAR measuring instrument, a thermometer, a rainfall and humidity sensor, a wind direction sensor and the like which are integrated in a weather station. Wherein the PAR measuring instrument is used for monitoring the illumination condition in the field in real time; the thermometer is used for measuring the atmospheric temperature; the rainfall and humidity sensor is used for monitoring the rainfall intensity and the air humidity; the wind power and wind direction sensor is used for monitoring wind power level and wind direction. The weather station can send the obtained weather data to the intelligent controller, the algorithm in the intelligent controller can compare and analyze the collected real-time data with preset data, the angle of the photovoltaic panel which needs to be adjusted at the moment is derived, the intelligent controller sends an adjusting command to the motor, and the motor drives the rotating shaft which controls the altitude angle and the azimuth angle according to the command to adjust the photovoltaic panel to the proper angle.
Thirdly, in particular to the decision of the algorithm, the practical implementation finds that the light demand is different at different stages in the whole growth cycle of the wheat. During the winter period, the light required by winter wheat is very low, about 400 mu mol/m 2 S, if PPFD collected by the weather station is more than 800 mu mol/m 2 When the sunlight is irradiated by the sunlight, the intelligent controller drives the motor to adjust the vertical sunlight of the uniform-light photovoltaic panel according to the instruction of the algorithm, as shown in fig. 6, the illumination below the uniform-light photovoltaic panel can still meet the condition; when PPFD is less than or equal to 400. Mu. Mol/m 2 At/s, such as during some periods of the evening and morning or in cloudy or poor air quality weather, the system can cause the photovoltaic panel to level with the sunThe rows are not shielded from light, see fig. 6. Moreover, the light homogenizing plate is arranged on the photovoltaic plate, so that a high-standard low-illumination light homogenizing environment is formed below the light homogenizing photovoltaic plate when the light homogenizing photovoltaic plate is perpendicular to sunlight, the situations of jump and over-low illumination intensity cannot be caused, and the quality of the low-illumination light homogenizing environment can meet the illumination requirement of the wheat during overwintering. During the filling period of wheat, the required illumination is relatively large, most of the time (except some time possibly with too strong illumination, such as noon) needs to allow as much sunlight to penetrate through the system to grow, and at this time, the system can adjust the photovoltaic panel to be parallel to the sunlight, and refer to fig. 6. In addition, during the whole growth process of wheat, in the noon or when the sunlight is too strong, i.e. the general PPFD is more than 1800 mu mol/m 2 During the time of/s, photosynthesis and normal growth of wheat can receive apparent suppression, and the system also can the photovoltaic board adjust at this moment as shown in figure 7 to shelter from sunshine, prevent that illumination from too strong and inhibiting the photosynthesis of wheat, and then improve the output of wheat, make full use of sunlight generates electricity simultaneously.
Fourth, the system has strong adaptability and superiority in dealing with extreme weather. The algorithm in the system is better for extreme weather determination than for conventional determination, i.e. the system may implement additional strategies in case of strong winds, heavy rain, severe drought, etc. If in strong wind weather, the system can adjust the photovoltaic panel to be parallel to the wind direction to avoid damage; the photovoltaic panel can be adjusted to be parallel to the ground in rainstorm weather so that raindrops can fall to the field uniformly. Note that to protect the facility, the decision in the algorithm for strong winds is prioritized over heavy rains, as strong winds are more likely to damage the system facilities. In addition, when the system identifies the high-temperature drought condition, the photovoltaic panel is always kept perpendicular to sunlight, so that the water evaporation under the photovoltaic panel is reduced, and the loss of crops caused by yield reduction due to drought is reduced.
The adopted power generation strategy of the photovoltaic panel does not influence the illumination required by the growth of wheat, and the illumination intensity can be reduced to promote the continuous growth of wheat when the wheat is inhibited by strong light, and meanwhile, the power generation of the photovoltaic panel is maintained. Therefore, in a comparative experiment, the yield of wheat can be improved by about 5% by adopting the photovoltaic agriculture-based illumination management system and management method, and the power generation can be improved by about 8% compared with the traditional photovoltaic agriculture system.
The angle of the dodging photovoltaic panel is intelligently adjusted according to the database and the algorithm established for the illumination data required by different planting methods, different plants and different growth periods, the problem that the traditional photovoltaic and agricultural combination method cannot be combined is solved, and more effective growth of crops and improvement of the power generation efficiency of the photovoltaic panel are achieved.

It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention.
