Description
Technical field
The present invention relates to agricultural automation control field, particularly relate to a kind of intelligent greenhouse system of air humidity Automatic adjusument.
Background technology
Greenhouse (greenhouse), also known as greenhouse, can printing opacity, insulation (or heating), be used for the facility of cultivated plant.In the season being not suitable for plant growth, breeding time and increase yield can be provided, be used for plant cultivation or the nursery etc. such as low temperature season warm season vegetable, flowers, forest.
The kind in greenhouse is many, can be divided into again many types according to different roof truss materials, lighting material, profile and condition etc. of heating, as glass greenhouse, plastics polycarbonate greenhouse; Single-ridgepole glasshouse, attached-greenhouse; Single roof greenhouse, two roof greenhouse; To heat greenhouse, unheating hothouse etc.Greenhouse structure answers sealing thermal insulation, but should be convenient to aeration-cooling.There is in modern greenhouse the equipment controlling the condition such as temp. and humidity, illumination, automatically control to create the optimal environmental condition needed for plant with computer.
Greenhouse generally needs to consider the following aspects:
1. light transmission
Greenhouse is daylighting building, and thus light transmittance evaluates one of greenhouse light transmission most basic index.Light transmittance refers to the percentage into the quantity of illumination in greenhouse and the outdoor quantity of illumination.Greenhouse light transmittance is by the impact of greenhouse glazing material light transmission and Keelof green house shadow factor, and along with the difference of Various Seasonal solar radiation angle, the light transmittance in greenhouse is also changing at any time.The height of greenhouse light transmittance just becomes plant growth and selects the direct acting factor of long-term cropping kind.Generally, muiti-span greenhouse is 50% ~ 60%, and the light transmittance of glass greenhouse is 60% ~ 70%, and greenhouse by solar heat can reach more than 70%.
2. heat insulating ability
Power consumption of heating is the major obstacle of greenhouse winter operation.Improving the heat-insulating property in greenhouse, reduce energy consumption, is the most direct approach improving hothouse production benefit.The insulation in greenhouse is than being the basic index weighing greenhouse heat-insulating performance.Greenhouse heat-insulating is than referring to greenhouse building enclosure area coverage that greenhouse light transmissive material area coverage that thermal resistance is less and thermal resistance the are larger ratio with ground area sum.Insulation, than larger, illustrates that the heat-insulating property in greenhouse is better.
3. durability
Greenhouse construction must consider its durability.Greenhouse durability is subject to the impact of the factors such as the bearing capacity of greenhouse material ageing-resistant performance, greenhouse main body structure.The durability of light transmissive material, except the intensity of self, also show that material transmissivity is constantly decayed along with the prolongation of time, and the attenuation degree of light transmittance is the deciding factor affecting light transmissive material service life.General steel construction greenhouse service life is more than 15 years.Require design wind, snow load 25 years one chance peak loads; 5 ~ 10 years service life of bamboo-wood structure simple greenhouse, design wind, snow load 15 years one chance peak loads.
Under Greenhouse operation is in high temperature, high humidity environment for a long time, the surface anticorrosion of component just becomes one of key factor affecting greenhouse service life.Steel construction greenhouse, stressed agent structure generally adopts light-gauge steel section, and self resistance to corrosion is poor, and adopt in greenhouse and must use the process of galvanizing by dipping surface anticorrosion, thickness of coating reaches more than 150 ~ 200 microns, can ensure the service life of 15 years.For timber structure or reinforcement welding truss structure greenhouse, must ensure to do one-time surface preservative treatment every year.
Air humidity in greenhouse on the transpiration of chamber crop, photosynthetic, disease occurs and disorder has remarkable impact.
1, air humidity affects transpiration, the power of transpiration except being moisture absorption, or the power of mineral nutrition transport.Air humidity is large, and transpiration is weak, and the ability of plant transport mineral nutrition just declines.The temperature of transpiration also adjustable vane, if temperature is high, air humidity is large, and transpiration is weak, and blade is just likely burnt.Indirectly can affect the alternation of wetting and drying of basin soil on the impact of transpiration, be unfavorable for rich water quality management; Air humidity is too low for a long time, can cause the necrosis of blade edge and blade tip, and main cause is because blade interior air cavity vapour pressure and extraneous vapour pressure have big difference, and causes blade interior steam under-supply and downright bad
2, the size of air humidity affects the opening and closing of plant stomata, and air humidity is excessive or too smallly all can cause stomatal closure, and plant stomata is closed, and CO2 can not enter mesophyll cell, and photosynthesis slows down and even stops.
3, the excessive breeding being conducive to germ of air humidity, the sprouting of most of fungal spore, the growth of mycelia all need higher levels of humidity, too low be conducive to insect pest generation, the generation of the mite classes such as such as two spotted spider mite is generally in the environment of high temperature low humidity.
4, high humidity can make blade face hydrogenesis, causes blade face cell rupture, makes plant weak simultaneously.
Existing Greenhouse System generally manually adjusts humidity, extremely bothers, and also has and regulates chamber humidity by computer, but is generally all direct interference, does not utilize the humidity of extraneous air, wastes energy.
