Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
The embodiment of the invention discloses a kind of environmental control of greenhouse method, device and intelligent greenhouse, to realize comprehensive regulation
Temperature and humidity in greenhouse, the normal growth for plant grows offer control environment.
See Fig. 1, a kind of environmental control of greenhouse method that the embodiment of the present invention provides, including:
S101, the air themperature information obtained in greenhouse and relative humidity information；
S102, described air themperature information and described relative humidity information is utilized to calculate the saturation water in current greenhouse
Steam pressure differences；
Needing explanation, the transpiration of plant is to absorb the major impetus source of moisture and Organic substance transhipment, to plant
Vital movement significant, although the factor affecting Crop transpirstion is a lot, but steam from blade face to the speed of external diffusion,
It is decided by the difference of the vapour pressure of intercellular substance and the vapour pressure of ambient atmosphere to a great extent.This steam pressure difference by temperature and
Humidity joint effect, therefore, the most only is difficult to make Crop transpirstion be maintained at suitably from temperature or humidity monofactor Regulate Environment
Level.
And in this programme, by controllable greenhouse saturation water draught head, can more efficient regulation Crop transpirstion level.This
In saturation water draught head (VPD, vapor pressure deficit) be Saturation vapor pressure difference, refer at a certain temperature, full
And the difference between the actual water vapor pressure in vapour pressure and air, what it represented is the journey of actual air distance water-vapo(u)r saturation state
Degree, by temperature and humidity joint effect.VPD affects the Guan Bi of plant stomata, thus controls plant transpiration, the physiology such as photosynthetic
Process, to forest ecosystem Evapotranspiration Processes and WUEL important.Therefore, regulate and control in this programme
VPD compared to the regulation and control to monofactor, can more efficient regulation Crop transpirstion level, thus beneficially crop to moisture and
The absorption of nutrient, promotes plant growth, growth, affects crop photosynthesis, Dry Matter, is finally reached the purpose improving yield.
A kind of method calculating VPD is provided in the present embodiment, particularly as follows:
VPD=0.611 × EXP [17.502 × Ta/ (Ta+240.97)] × (1-RH)；Wherein, in formula, EXP is with e as the end
The exponential function of number, Ta is greenhouse air temperature, and RH is relative humidity.
S103, judge whether described saturation vapour pressure difference is in default optimum range；
The most then perform S104；If it is not, then perform S105；
S104, judge that current greenhouse is as control environment；
S105, according to described saturation vapour pressure difference and described default optimum range, perform corresponding control manipulation.
Concrete, in this programme, when saturation vapour pressure difference current indoor being detected is in optimum range, then illustrate
Current greenhouse is control environment；If detecting, the saturation vapour pressure difference of current indoor is not at optimum range, then illustrate
Current greenhouse is the environment being not suitable for plant growing, then perform the control manipulation of correspondence, until the saturation vapour in greenhouse
Till pressure difference is in optimum range.
The embodiment of the invention discloses a kind of concrete environmental control of greenhouse method, relative to a upper embodiment, this enforcement
Technical scheme has been made further instruction and optimization by example.Concrete: according to described saturation vapour pressure difference and described default
Optimum range, performs corresponding control manipulation, including:
Judge that whether described saturation vapour pressure difference is higher than described default optimum range；
The most then perform moistening and lowering temperature operation；If it is not, then perform wet down warming operation.
It should be noted that the suitable VPD of plant growth should be maintained in an optimum range, fit if VPD exceedes this
Preferably scope, then judge current greenhouse as high temperature low moisture environments condition, in this case, the crop root water suction in greenhouse can not
Meeting rising needs, crop is survived by reducing transpiration, such as, reduce leaf area or close the modes such as pore, but no matter
Use which kind of mode that plant strain growth all can be made slow, Pollen Activity also can be caused to decline, increase fallen flowers；Therefore, at the present embodiment
In, if be detected that VPD is beyond this optimum range, then greenhouse is performed moistening and lowering temperature operation, to improve the humidity in greenhouse, fall
The temperature of low temperature chamber, makes the VPD value in greenhouse be down to optimum range；After detecting that VPD is down to optimum range, then stop performing
Moistening and lowering temperature operates；
If VPD less than optimum range, then judge current greenhouse as high humidity environment, in this case, humidity crosses high crop
Excessive growth easily occurs, also can affect Pollination Fertilization, thus impact is beared fruit, and also results in Fructus Lycopersici esculenti, cucumber leaves calcium deficiency, magnesium deficiency, blade
Chlorosis, photosynthetic decline.Therefore, in the present embodiment, if be detected that VPD is less than this optimum range, then greenhouse is performed fall
Temperature wet operations, to reduce the humidity in greenhouse, makes the VPD value in greenhouse rise to optimum range；When detecting that VPD rises to optimum range
Afterwards, then stop performing wet down warming operation.
See Fig. 2, in this programme, the optimum range of VPD is set as 0.3～1kPa；If higher than 1kPa, then perform to add
Wet cooling operation；If less than 0.3kPa, then perform wet down warming operation, until optimum range regulates and controls to optimum range.
The embodiment of the invention discloses a kind of concrete environmental control of greenhouse method, relative to a upper embodiment, this enforcement
Technical scheme has been made further instruction and optimization by example.Concrete:
Described execution moistening and lowering temperature operates, including:
Calculate the first difference of described saturation vapour pressure difference and described optimum range maximum；It is first poor with described to determine
The first operation grade that value is corresponding；Generate the operational order corresponding with described first operation grade, and send to mini-mist spray system.
Concrete, in the present embodiment, when VPD is too high, can be humidified by mini-mist spray system, reach humidification, cooling effect
Really, thus reduce VPD；It is understood that be typically different owing to VPD exceeds the degree of optimum range, therefore can set super
Go out multiple rate ranges of optimum range, determine, according to the difference of current VPD Yu normal range, the grade model that current greenhouse is in
Enclose, generate corresponding operational order, operational order here and moistening and lowering temperature according to the moistening and lowering temperature degree that rate range is corresponding
Degree is corresponding, i.e. difference is the biggest, more needs moistening and lowering temperature, and the spray amount that operational order controls spraying system generation is the biggest.
Same, in this programme described execution wet down warming operation, including:
Calculate the second difference of described saturation vapour pressure difference and described optimum range minima；It is second poor with described to determine
The second operation grade that value is corresponding；Generate the operational order corresponding with described second operation grade, and send to ventilating system.
Accordingly, in the present embodiment, when VPD is too low, greenhouse need to be carried out wet down, generally ventilate.Same, by
It is typically different less than the degree of optimum range in VPD, therefore can be set lower than multiple rate ranges of optimum range, according to working as
The difference of front VPD and normal range determines the rate range that current greenhouse is in, and heats journey according to the wet down that rate range is corresponding
Degree generates corresponding operational order, and operational order here is corresponding with moistening and lowering temperature degree, i.e. difference is the biggest, more needs fall
Wet, the ventilation levels that operational order controls ventilating system is the strongest.
It should be noted that owing to greenhouse temperature is generally greater than ambient temperature, the therefore ventage in this programme
What system played primarily serves the purpose of wet down, but in order to prevent only by ventilate can not effectively to greenhouse wet down, therefore
In scheme, the operational order corresponding with the second operation grade is sent after ventilating system, also includes:
If after the first predetermined time interval, detect that the saturation vapour pressure difference in current greenhouse is less than described pre-
If optimum range, then send instruction of heating to heating system.
Visible, if after first scheduled time of interval, only ventilate and can not say the optimum range that VPD improves, then can pass through
Heating system performs warming operation, to improve VPD.
It should be noted that be possible not only to set the VPD value calculating greenhouse in real time in this programme, it is also possible to set with in advance
The VPD value in interval calculation of fixing time greenhouse, and the VPD calculated every day can be recorded as required and not in optimum range
Performed operation, is analyzed for staff；And the effective time of the VPD data of preservation can be set, if VPD number
According to beyond the effective time preserved, the most directly delete.
Concrete, this programme, in order to prevent owing to mini-mist spray system, ventilating system or heating system break down, causes
The temperature and humidity of indoor can not be adjusted in time, a time threshold can be set, when detecting the VPD value in current greenhouse not suitable
Starting timing time in the range of Yi, if after detecting more than time threshold, the VPD value in greenhouse still can not regulate and control to optimum range,
Then judge mini-mist spray system, ventilating system or heating system are likely to occur fault, then analyze the system broken down, and and
Shi Shengcheng information, and send to staff.
Visible, temperature and humidity is combined by this programme, can solve temperature in greenhouse flower mutual with humidity
The contradiction of impact, controls more comprehensive than single environment；Compared to traditional fuzzy control, more favorably realize the essence of greenhouse
Really control, and VPD is the implication in atmospheric physics kinetics, is to carry out from the mechanism of Crop transpirstion by VPD Regulate Environment
Consider, regulate and control more science than traditional empirical formula.
