And Electric air valve 5 is mounted on the first air hose 3 and the second air hose 4, blower 2 is located at the first air hose 3 (or second air hose 4)
On.Electric air valve 5 can use the Electric air valve 5 of model D341W-1C, and Electric air valve 5 and blower 2 are by the control of controller 1
System, in ventilation, blower 2 is gone out from 3 exhausting of the first air hose, and greenhouse can supplement air quantity from the second air hose 4 automatically, to realize temperature
The ventilation of indoor and outdoor.In ventilation process, directly the air of certain temperature in greenhouse is drained, outside air is discharged into, in this way may be used
Quickly the indoor temperature of temperature is adjusted to equal with ambient temperature.Greenhouse biggish for area, settable multiple groups ventilation module
It is aerated heat exchange simultaneously, guarantees heat exchange efficiency.
In the embodiment, cooling and warming module includes refrigerating and heating machine 6 and the circulating line that connect with refrigerating and heating machine 6
7.Wherein, refrigerating and heating machine 6 is conventional structure, and which is not described herein again for specific structure, and the circulation for being able to achieve hot and cold medium is defeated
It send, vertical inner wall spiral of the circulating line 7 close to greenhouse is installed.Control of the refrigerating and heating machine 6 by controller 1, the heat of conveying
When medium or cold medium recycle in circulating line 7, heat exchange is carried out with the indoor air of temperature, realizes that temperature is adjusted.In addition,
It is equipped with heat exchange fin on the surface of circulating line 7, helps to improve heat exchange efficiency.
In the embodiment, Illumination adjusting module includes transparent panel 8, transparent gasbag 9, gas tank 10, appendix 11 and air pump 12,
Tip portion of the transparent panel 8 as greenhouse, and transparent panel 8 is double-layer structure, in the centre of transparent panel 8, there are cavity, transparent gas
Capsule 9 is layed in cavity, and 11 one end of appendix is connected to transparent gasbag 9, and the other end is connected to by air pump 12 with gas tank 10, gas tank
Colored gas is stored in 10.Transparent panel 8 is arc or planar structure, and transparent gasbag 9 is paved with the cavity of entire transparent panel 8,
The colored gas stored in gas tank 10 can be transported in transparent gasbag 9 by air pump 12, keep transparent gasbag 9 no longer transparent, light
According to can not just pass through transparent panel 8, the effect of blocking is realized；Air pump 12 can take out the colored gas in transparent gasbag 9 can gas tank 10
It is interior, allow transparent panel 8 that illumination can be connected.Particularly, above-mentioned colored gas can be nitrogen dioxide, chlorine or ozone etc..
Particularly, the edge of above-mentioned transparent gasbag 9 is connect by drawstring 13 with the cavity inward flange of transparent panel 8.Drawstring 13
Can make inside transparent gasbag 9 no matter whether there is or not gases can preferably be laid in cavity, prevent transparent gasbag 9 from crispaturaing, shadow
Ring using effect.

Preferable intensity, while double-layer structure also has preferable thermal insulation effect.
In the embodiment, temperature detecting module includes the temperature sensor 14 outside the greenhouse and is set to the indoor temperature of temperature
Spend sensor 14, the model TMP275 of temperature sensor 14.
The present invention also provides a kind of greenhouse constant temperature intelligent control methods, utilize above-mentioned device, and method is to control
Pre-set target temperature T in device 10, controller 1 carries out the adjustment of temperature every time t, and the purpose of adjustment is to control in greenhouse
Temperature tends to target temperature, the specific steps of adjustment are as follows:
Controller 1 obtains warm outdoor temperature T by temperature detecting moduleOutsideAnd warm room temperature TIt is interior, and compare target temperature
Spend T0With warm outdoor temperature TOutsideAnd warm room temperature TIt is interiorSize:
If TIt is interior<T0, then need to heat up, controller 1 controls the conducting illumination of Illumination adjusting module and injects inside greenhouse, light irradiation
Enter the inside of sealing greenhouse, capable of making inside greenhouse, temperature rapid increase, while controlling cooling and warming module and being heated, until TIt is interior
=T0；Two heating means cooperatings, heating efficiency is obviously improved, and solar energy is utilized, and can reduce refrigerated medium hot-die
The energy consumption of block saves cost.
If T0<TIt is interior, then need to cool down, be divided into three kinds of situations at this time: if T0<TOutside<TIt is interior, then controller 1 controls Illumination adjusting mould
Block shielding light is irradiated into inside greenhouse, while controlling ventilation module and carrying out separate ventilation in greenhouse, and separate ventilation can be quick in greenhouse
Hot-air in greenhouse changes into outside air, realize fast cooling, work as TIt is interior=TOutsideWhen, stop ventilation, and control cooling and warming
Module starts to freeze, until TIt is interior=T0；It is consistent that internal and external temperature is first cooled to using separate ventilation in greenhouse, is then turned on refrigerated medium
Cooling efficiency equally can be improved in this way, and reduce the energy consumption of cooling and warming module for thermal modules, save cost.
If T0<TIt is interior<TOutside, then controller 1 controls Illumination adjusting module shielding light and is irradiated into inside greenhouse, while controlling refrigeration
Heating module freezes, until TIt is interior=T0；This is but this feelings the case where uniquely relying only on cooling and warming module work temperature adjustment
Condition is simultaneously few.
If TOutside<T0<TIt is interior, then controller 1 controls Illumination adjusting module shielding light and is irradiated into inside greenhouse, while controlling ventilation
Module carries out separate ventilation in greenhouse, two ways while cooperating, and cooling effect is significant, until TIt is interior=T0。
In this method, above-mentioned time t is 10~15min, i.e., carries out a temperature adjustment every 10~15min, make greenhouse
It is interior to keep preferable constant temperature effect.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.
