Degree, here are white, are reduced at night and absorb crops radiation dispersed heat.Daytime, sunshade rose, and night is by sunshade
It reduces, the height after reduction is higher 10cm-20cm than the height of plant growth.
5. connecting a data converter in each sensor, data converter is by the temperature, humidity, light of sensor transmissions
It carries out passing to data processor after conversion process according to intensity data, in the data and large database concept that data processor obtains
Data are compared.When variant between the optimum value needed for the crop growth in the data and database of acquisition, data
Processor delivers a signal to central processing unit, and central processing unit, data processor are located at the centre position in entire canopy, is convenient for line
The arrangement on road, central processing unit transmit different signals to controller according to difference type, and controller is according to the temperature, wet in canopy
Degree, the intensity of illumination control adjusting of wind turbine, sunshade switch, controller manipulates the nearest wind of sensor of Distance Transmission information
Machine and sunshade.When the humidity ratio optimum value that sensor obtains is high, the water of wet curtain is reduced and reduces fan delivery carrying out
Dehumidifying, when the humidity ratio optimum value that sensor obtains is low, the water and increase fan delivery that increase wet curtain are humidified.When
When temperature of shed is higher, sunshade is opened, sunshade is closed when temperature of shed is relatively low to increase the intensity of illumination in canopy.
6. non-interference between sensor, data processor can handle simultaneously the data from different sensors and respectively with
Database is compared.
Compared with prior art, the technical effects of the invention are that：
1. the wind turbine of different location may be implemented in technical solution through the invention, the sunshade of different height works independently, mutually not
Interference, the water inlet confluent synchronous interaction control of wet curtain upper portion, can either be to temperature, humidity, the illuminance in photovoltaic green-house
It carries out subregion to be precisely controlled, while also saving the energy.
2. technical solution can solve photovoltaic green-house winter there are temperature inversions to damage crop growth through the invention
Problem individually controls the adjustable height of each sunshade by liftable sunshade, effectively prevents inversion in winter-spring season canopy and leads
The crop frozen injury phenomenon of cause.
3. through the invention technical solution may be implemented the crop growth in photovoltaic green-house be constantly in best temperature,
In humidity, light environment；
4. by intelligent control, the artificial monitoring cost of agricultural planting and error are reduced；
5. conducive to the growth of crops inside greenhouse, can be conducive to realize Agricultural Three-dimensional production, be collect low-carbon, energy-saving and environmental protection in

Road is connected with cistern 22, water circulating pump 23, ensure that wet curtain flow persistent loop.Both sides face wall arranges in photovoltaic green-house 1
Several wind turbines 24 are installed, the positional distance wall that wind turbine 24 is installed is remote apart from the position of wall compared with wet curtain 2, can carry out different angles
Degree conversion.Further include several sunshades 3 of distributing installation above photovoltaic green-house 1, sunshade 3 is black above, absorbs light daytime
It according to heat, is supplemented when evening, temperature was low to the growth temperature needed for plant, here is white, is reduced at night and absorbs crops
Radiate dispersed heat, liftable.Each wind turbine 24, sunshade 3 are non-interference in working condition, for crops in photovoltaic green-house
Growth establish large database concept, database contains optimum temperature needed for Planting Crops growth, humidity, intensity of illumination number
Central processing unit 4 and data processor 5 are installed according to, photovoltaic green-house center, according to 1 environment different subregions domain of photovoltaic green-house,
Each region is respectively arranged temperature-humidity sensor 6, and the setting position of sensor 6 is temperature, humidity, intensity of illumination change greatly
Region, data acquisition between each sensor 6, transmit it is non-interference.Each sensor 6 corresponds to a data converter 7, is convenient for
Independent transmission data is separately installed with controller 8 at each wind turbine 24 and at sunshade 3.
Embodiment two
By taking the photovoltaic green-house application present invention at Qingdao City, that is, ink-covered area Hua Shenglvneng solar energy farm one as an example, the present embodiment is except following
It is identical as embodiment one outside feature.
Temperature inversion in the photovoltaic green-house is to influence one of plant growth in canopy to endanger element greatly all the time, in Winter-Spring
In season, it sometimes appear that the temperature situation lower than outside canopy instead in greenhouse, this phenomenon is referred to as " inversion ", usually before midnight
After occur, the crops of plantation are very sensitive to this, just will produce freeze injury unless you give your whole attention to it.Therefore, with the application of the invention, on daytime
When, sunshade is risen, daylight intensity is big, and when temperature is higher, sensor 6 transfers data to data converter 7, data
Converter 7 is transferred to data processor 5, and data processor 5 is transferred to central processing unit 4, centre after being handled data
Data are compared reason device 4 with up to the data in database, the difference type of comparison are transferred to controller 8, controller 8 will
Sunshade 3 is opened；Conversely, intensity of illumination is small, when temperature is relatively low, controller 8 closes sunshade 3.
Night, canopy temperature decline, and sunshade 3 highly reduces, and the height after reduction is higher than the height of crop growth
10cm-20cm, it is therefore an objective to which the growth for neither influencing crop can also play the role of heat preservation.Sunshade 3 is black above, in vain
It absorbs illumination heat, is supplemented when evening, temperature was low to the growth temperature needed for plant, and here is white, reduces and inhales at night
It receives crops and radiates dispersed heat.
Likewise, for the control to humidity in the greenhouse, when the humidity ratio optimum value that sensor 6 obtains is high, reduce
The water and reduction fan delivery of wet curtain dehumidify, and when the humidity ratio optimum value that sensor 6 obtains is low, increase wet curtain
Water and increase fan delivery are humidified.
