The indoor light intensity in real time of collection, the master controller of main control node obtain what each illumination monitoring node was detected by intervals
Needed for light intensity data, with greenhouse normal work, light intensity brightness value is contrasted, to judge that whether current temperature indoor illumination intensity exists
Prescribed limit, if the light intensity data for detecting exceedes 1.2 times of light intensity illumination needed for greenhouse normal work, master controller is recognized
It is exceeded for now light intensity, need to weaken 0.9 times of intensity of illumination needed for the intensity of illumination to normal work in greenhouse, master controller
Instruction is sent to collapsible photovoltaic film sun-shading mechanism, drives reducing motor to drive sun-shading mechanism level to uphold, on sun-shading mechanism
The initial glazed area of photovoltaic film plate of covering is in partially open state.Master controller sends instruction again, gathers sunshade again
Light intensity data in greenhouse under plate, finely tunes glazed area on photovoltaic film sunshading board according to current light intensity numerical value, adjusts indoor most suitable
The light intensity environment of suitable plant growth.When indoor light intensity numerical value is close to pre-designed lower limit, master controller sends instruction,
Reducing motor is driven to drive sun-shading mechanism level retraction, glazed area on adjustment photovoltaic film sunshading board, until greenhouse is returned again
To the intensity of illumination needed for normal work.In system work process, by LCD display module, indoor current light is shown in real time
The ambient parameters such as intensity, temperature, humidity and working state of system parameter etc., and when indoor illumination intensity is inadequate, in time
Report to the police and start the corollary equipments such as artificial light source, keep the indoor illumination condition for most adapting to plant growth.
The foregoing is only presently preferred embodiments of the present invention, all impartial changes done according to scope of the present invention patent with
Modification, should all belong to the covering scope of the present invention.
