Description
Technical field
The present invention relates to a kind of to realize on-the-spot automatically measuring, easily extension, sample frequency can network adjustment, measurement position phase
To unification, the heliogreenhouse plastic greenhouse film combination property Internet of Things Auto-Test System of synchronal data sampling.
Background technology
Facility cultivation refers to utilize heliogreenhouse, hot house or other facility, and artificially creating for crop growth can
The microclimate environment of control, applicable crop growth, to reach the purpose of manual adjustment crop production.Along with modern agriculture skill
The development of art, energy saving sunlight greenhouse plantation form develops rapidly in vegetables industry, and bring for growing vegetables family can
The economic benefit seen.
Plastic sheeting is used for greenhouse and booth, the most universal, by developed country be referred to as " plastics cultivation ",
" ethylene agricultural ", plastic greenhouse film has become the main non-transparent covering material of energy saving sunlight greenhouse the most.
The combination properties such as the color and luster of plastic greenhouse film, heat insulating ability, light transmission, the light transmittance rate of decay and anti-drop property directly affect
The light heat environment condition in greenhouse, and the yield of the chamber crop directly affected and quality, and then directly affect greenhouse
Planting benefit.
Along with plantation and the improving constantly of management technique, people are more and more higher to the requirement of environmental control of greenhouse ability, from
And canopy film combination property is had higher requirement.Canopy film manufacturer often through methods such as raw material, processing technique and formula,
The combination property of canopy film is improved.
The accurately measurement of canopy film combination property is the premise improving canopy film combination property.
At present, the domestic measurement to agricultural film combination property, usually take on-the-spot manual measurement mode, i.e. periodically to scene
Measure parameters, not only waste time and energy, and it cannot be guaranteed that the accuracy of data, seriality, integrity and synchronicity.Particularly
When measuring the key factor-canopy film light transmittance in canopy film combination property, inside and outside commonly used hand-held illumination measurement amount greenhouse
Intensity of illumination converses intensity of illumination.Due to the inconsistent change particularly measuring angle in the position of artificial hand-held illumination meter, no
Same people, the most in the same time intensity of illumination measured value are widely different, and the accuracy of data cannot ensure at all.It addition, when to polylith film
Light transmittance when carrying out comparative study, can only timesharing measure, it is impossible to the combination property of polylith canopy film is carried out synchro measure,
Due to the light transmittance sensitivity to direction of illumination, also significantly impact the accuracy of measurement data.
At present, technology of Internet of things is not also not applied in canopy film combination property on-the-spot test, it is impossible to comprehensive to canopy film
Accurate, continuous, synchro measure can be carried out, the most canopy film combination property is not carried out the system of real-tune TT & C.It is thus desirable to exploitation
Go out a kind of monitoring canopy film that can monitor in real time, that adapt to different occasion, that extensibility height strong, intelligent, practicality are good to combine
Close performance monitoring system.
