Description
Technical field
The present invention relates to curtain control field, particularly relate to a kind of curtain self-adapting regulation method.
Background technology
Just there has been window in China since ancient times, and just someone expects there is thing window to covering window, so just there has been curtain, curtain is articles for use very common in our daily life.Curtain has following effect:
1, privacy is protected.
For one family, no one likes the every act and every move of oneself within others' visual field.From this point, different room areas, the degree of concern for privacy has again different standards.This kind of kinsfolk's public activity region, parlor, the requirement for privacy is just lower, and most family parlor is all that curtain is pulled open, and is in decoration state in most cases.And for the region such as bedroom, toilet, people not only require can't see, and require that shadow all be can't see.This selects different problems with regard to the curtain causing zones of different.Parlor we may select partially transparent a cloth, the cloth of thicker matter is then selected in bedroom.
2, light is utilized.
In fact protect the principle of privacy, or process from obstruction light aspect.Mentioned herely utilize light, referring to when protecting privacy, effectively utilizing the problem of light.The room of such as one deck, everybody does not like other to stroll about and sees indoor every act and every move.But haul thick curtain for a long time and affect natural lighting again.So the frivolous cord being similar to yarn curtain one class has just arisen at the historic moment.
3, decoration function.
Decorated wall surface curtain, for a lot of average family, is the maximum ornament of metope.Still it is some the plainly-packed families for some " Sibai is landed ", and except a few width picture frame, the thing on possible metope is just left curtain.So whether beautiful the selection of curtain is, may often there is very important effect.Equally, for the family of hard-cover, suitable curtain will make that household is more beautiful more has individual character.
4, absorbing sound and lowering noise.
We know the part of propagation of sound, and high pitch is straightline propagation, and window-glass is also very high for the reflectivity of high pitch.So, there is the curtain of suitable thickness, the reverberation effect of room sounding can be improved.Equally, overdrape is also conducive to the noise of absorption portion from outside, improves indoor acoustic environment.
We are adjusting light intensities by the function that curtain is maximum, and existing curtain is all generally manual, and people need to go to window side and adjust, generally all automatically can not adjust the opening degree of curtain according to the light of indoor.
Light sensor is one of modal sensor, it of a great variety, mainly contains: photoelectric tube, photomultiplier, photo resistance, phototriode, solar cell, infrared ray sensor, UV sensor, optical fiber type photoelectric sensor, color sensor, CCD and cmos image sensor etc.Its sensitive wave length, near visible wavelength, comprises IR wavelength and ultraviolet wavelength.Optical sensor is not confined to the detection to light, and it can also form other sensors as detecting element, detects many non electrical quantities, as long as these non electrical quantities are converted to the change of optical signal.Optical sensor is one of maximum, most widely used sensor of current production rate, and it is automatically controlling and is occupying very important status in non-electrical quantity measurement technology.
Light sensor is mainly used in the electronic product light automation fields such as solar lawn lamp, Light-operated night lamp, camera, watch-dog, light-operated toy, sonic-opticalcon trolled switch, camera, antitheft wallet, light controlled music box, birthday musical candle, music cup, human body inductive lamp, human induction switch.
In light sensor, the simplest electronic device is photo resistance, and it can respond to the light and shade change of light, exports the faint signal of telecommunication, amplifies process, can control the automatic switch of LED lamp by simple electronic circuit.For long-range lighting, as street lamp, garden lamp, Lawn lamp etc. all can be economical and simply realize energy-conservation automatic control.
