Description
Technical field
This utility model relates to a kind of roller shutter machine of solar greenhouse control system, is specifically related to a kind of according to local longitude and latitude letter
Breath calculates sun set/raise time every day and combines the technology that local weather situation realizes being controlled shutter, belongs to agricultural machine
Tool equipment technical field.
Background technology
Heliogreenhouse is a kind of greenhouse that the northern area of China is exclusive, has good heat insulation, invests low, the saving energy etc.
Feature, is especially suitable for northern China rural area and uses.Ending 2014, China's heliogreenhouse industry area about 92.7 ten thousand is public
Hectare, vegetable consumption demand is rigidity growth trend.In the daily management of day-light greenhouse, the work of winter job management is strong
Degree is very big, and especially in the early stage of development, wherein timing launches and pack up the sheath such as straw screen or mat, cotton-wadded quilt to be exactly a time-consuming expense
The work of power.
The appearance of electric screen robling machine to some extent solves the problem that Traditional Man rolling fashion exists, the biggest
Alleviate greatly blue-collar intensity, peasant household is emancipated from hard work；On the other hand, rolled up by motor
Curtain, operating rate is accelerated, and makes covering roll and substantially shortens with the time launching to spend, and crop can obtain the most longer light
According to the time, improve the economic benefit of peasant household.
After either, wall is fixed or the self-propelled shutter in canopy face, and it runs and controls generally to use following two mode to enter
OK: one is manually to connect shutter to control power supply, and covering is rolled or launches, and Field Force estimates covering position, when reaching
When rising or falling position, disconnect rolling screen electromechanical source.Wherein the connecting and disconnecting of power supply can be manual directly control, it is also possible to
The remote controller with certain remote control distance is used to control.The disadvantage of this mode is that scene personnel to be had stare at and keep, shutter
Operation be unable to do without people all the time.Two be in order to meet when covering is at correct position, it is achieved shutter autostop require and
The control system of the tape travel switch increased.Comparing first kind of way, the advantage of this mode is no longer to need after shutter starts
Want peasant household to stare at specially to keep, can self-stopping after running to the precalculated position determined by proximity switch.But actual motion is deposited
In some problems, and thus cause various shutter accident, as due to spool self-deformation, covering its thickness change and
The covering that travel switch inefficacy etc. causes is climbed over the walls, spool is twisted into two parts.
In order to improve automatization, the intelligence degree that shutter controls, occur in that and combine humiture and illumination inside and outside greenhouse
The ambient parameters such as intensity control the controller of covering folding and unfolding, and image processing techniques is detected phase with ambient parameter by some units
In conjunction with developing intelligent curtain rolling machine control system.But it is more that these systems install sensor, connects up relative complex, relatively costly,
The currently mainly Experimental Base in relevant Demonstration Base and research institutions is applied more.In November, 2015, by Shouguang, Shandong
100 heliogreenhouse peasant households in three unincorporated village, area are visited, and do not find that a family this price of employing is of a relatively high, operate phase
To complicated system.
