The operation of multiple motors.
Every day, the sun comes up in the east and falls from west.Therefore the sunlight reflecting mirror system of WO00/66947
System is at west at sunset.The use of the sensor unit disclosed in WO00/66947 does not ensures that sunlight
Mirror system systematically rotates back to east so that sunlight mirror system is in the sunrise in next early morning
Time towards east.Therefore manually intervene to rotate sunlight mirror system needing after the sunset so that it
Next early morning is again towards east.This for the user of this sunlight mirror system be one time-consuming and
The process of constraint.Owing to the sunlight mirror system disclosed in WO00/66947 the most systematically rotates back to
East with in next early morning towards the sun, therefore the sunlight mirror system of west is towards west
Identifying a point in sky, for this point, four sensors are phases for the response of the intensity of the light received
With.But, this point may be in preset time the position not corresponding to the sun, because the sun may position
In with solar mirror system towards direction in opposite direction, such as relative to solar mirror system towards
Direction rotate 180 °.The position of mirror device is not the most optimum, and does not allows for whole day tracking sky
The aerial sun.Therefore, the intensity reflexing to the light on residence is significantly attenuated.Which compromises sunlight reflection
The illumination of the efficiency of mirror system and the worker in residence and/or habitant is experienced.
WO2009/031726 discloses a kind of solar tracking sensor using solar tracking sensor unit
Unit, solar tracking sensor unit includes that upright barrier is with the sensor outer housing by including four sensors
Solar panels be separated into specific region, four, the four corners of the world.East and West direction drives motor and north-south to drive motor

It is that four sensors are directed towards the sun.When solar panels are when being fully rotated at sunset to west,
The limit switch of corresponding position and runs when solar panels arrive at certain position.Correspondingly, when
When special time period passes, East and West direction drive motor rework so that solar panels automatically return to towards
The predetermined home position in east is with at sunrise towards the sun.
Solar tracking sensor unit disclosed in WO2009/031726 requires to realize by limit switch control
Intervalometer.This intervalometer is touched when arriving the precalculated position restriction of limit switch in the position of mirror device
Send out.This precalculated position limits and drives motor to have to pass through before re-operating solar panels in East and West direction
Time period and the predetermined home position that must arrive of solar panels must be calibrated in advance.Intervalometer and restriction
Using it is thus desirable to pass with additional position sensor, the time of solar tracking sensor unit couples of switch
Sensor and the realization of programmable unit.This make to design this kind of solar tracking sensor unit become complicated and
Expensive.It addition, in the case of cloudy weather, the light intensity that the solar panels of solar tracking sensor unit are collected
Degree may be too low so that the normal work of two motors can not be allowed.Therefore solar tracking sensor unit freezes
Junction then continues rotating of its whole day to a direction, the sun.If cloud dissipates, then light intensity may foot
Enough allow the work of two motors.But, solar tracking sensor unit is no longer towards the sun, and its position
Therefore put is not optimum for whole day follows the trail of the sun that it is aerial.
It is an object of the invention to disclose the system of a kind of shortcoming overcoming prior art identified above.More
Body ground, it is therefore an objective to open one produces solar tracking reflecting mirror with simple, high energy efficiency and reliable way and sets
The system of the optimal location more accurately of standby whole day.
Summary of the invention
According to the first aspect of the invention, daylight is reflected towards skylight by a kind of being used for by object defined above
Solar tracking mirror system realize, described solar tracking mirror system includes:
Mirror device, including:
It is adapted to be reflected towards daylight the mirror in described skylight；
It is adapted to the mirror support structure supporting described mirror and rotating on described skylight；
It is adapted to rotate the motor of described mirror support structure；
It is adapted to determine the control unit of the optimal location of the first estimation of described mirror device；
It is characterized in that:
Described control unit includes three optical sensors being adapted to measured light intensity so that:
Described three optical sensors are arranged in described control unit according to triangle manner；And
Described three optical sensors are spaced apart each via protective shield；
Described control unit is further adapted into the optimum determining described mirror device according to described light intensity
Position；
Described mirror device is further adapted into when the 3rd light intensity in described light intensity is more than according to institute
State the first light intensity in light intensity or estimate described first during intensity threshold that the second light intensity determines
Optimal location is corrected as described optimal location.
Skylight is the opening of printing opacity, such as fills the element of building enclosure opening.For daylighting purpose, skylight
Form all or part of of space on the roof of building.Solar tracking mirror system quilt according to the present invention
It is adapted to be arranged in skylight so that the mirror support structure of solar tracking mirror system is adapted to can
Rotate independent of skylight.Mirror device includes the mirror being adapted to that daylight is reflected through roof openings.To mirror
The control position based on the sun of the position of son.
Solar tracking mirror system according to the present invention includes three optical sensors, described three optical sensors
Arrange in a control unit according to triangle manner.Each optical sensor is spaced apart by protective shield.According to this
Invention, the 3rd optical sensor is employed to ensure that mirror device is in errors present never, i.e. mirror device is complete
The direction of the sunlight intensity maximum of it object mirror equipment seizure all the time and reflection.Such as, at sunset, too
Sun following reflex mirror system west.At sunrise and be enough to allow three optical sensors at sunlight intensity
During measured light intensity, control unit is according to the first and second light measured by the first and second optical sensors respectively
Intensity determine mirror device first estimation optimal location, simultaneously solar tracking mirror system still towards
West.But, at sunrise, the sun rises in the Orient, and the solar tracking the most such as deviating from west is anti-
Penetrate mirror system and rotate 180 °.In other words, mirror is determined when solar tracking mirror system not region be directly facing the sun
The optimal location of the first estimation of son.The 3rd optical sensor blocked by other two sensors can measure
Three light intensities.Control unit considers that this 3rd light intensity is to determine the optimal location of mirror device further.
It is true that when the 3rd light intensity is more than the intensity threshold determined according to the first light intensity or the second light intensity,
3rd optical sensor provides the preferred mirror device of optimal location existed than the first estimation to control unit
The instruction of position.In other words, the 3rd optical sensor provides instruction to have what mirror device caught and reflected
Sunlight intensity is by than the sunlight intensity that mirror device caught and reflected at the first optimal location estimated more
The information of the optimal location of big mirror device.Such as, at sunrise, when the sun comes up in the east and works as
During solar tracking mirror system still west, the 3rd optical sensor measures what instruction was risen towards the sun
3rd light intensity of the light intensity in east.When this 3rd light intensity is more than intensity threshold, mirror device
Therefore optimal location is the position limited by the 3rd optical sensor.Intensity threshold is such as corresponding to the first light intensity
Maximum between degree and the second light intensity.Control unit is it is later determined that be different from the optimal location of the first estimation
The optimal location of mirror device, and the position that first estimates is corrected as this optimal location by mirror device.
On the other hand, when the 3rd light intensity is less than the intensity threshold determined according to the first light intensity or the second light intensity
Time, the 3rd optical sensor provides to control unit and does not exist than the first preferred mirror of optimal location estimated
The instruction of the position of equipment.Intensity threshold is such as corresponding to the maximum between the first light intensity and the second light intensity
Value.In other words, when the 3rd light intensity is less than the intensity threshold determined according to the first light intensity or the second light intensity
Time, the 3rd optical sensor provide the instruction institute's sunlight intensity that catches and reflect that there is not mirror device will ratio the
The mirror device that at one optimal location estimated, sunlight intensity that mirror device caught and reflected is bigger is
The information of excellent position.Therefore the optimal location of the first estimation and the optimal location of mirror device of mirror device are
Identical.Alternatively, described mirror device is further adapted into when the 3rd light intensity in described light intensity
During equal to or more than the intensity threshold determined according to the first light intensity in described light intensity or the second light intensity
The optimal location that described first estimates is corrected as described optimal location.
According to the present invention, the 3rd optical sensor is employed to ensure that mirror device is in errors present never, i.e.
The direction of the sunlight intensity maximum of the seizure of mirror device whole day object mirror equipment all the time and reflection.Such as, exist
At sunrise, it is possible to the sun is covered by cloud but sunlight intensity is the most sufficiently large to allow solar tracking reflecting mirror
System works.Solar tracking mirror system in fact towards east, but owing to being broken sky, the most too
Sun following reflex mirror system search reflexes to the intensity of the light in skylight more than towards mirror device during east
First optimal location estimated.The intensity of solar tracking mirror system mark daylight is more than towards during east
The point in the north, and solar tracking mirror system is it is thus determined that the north is mirror device first estimates
Excellent position.The 3rd light intensity that 3rd optical sensor is measured is less than according to respectively by the first and the of control unit
The intensity threshold that first light intensity of two optical sensors measurements or the second light intensity determine.Therefore mirror device will
Its position is corrected as the optimal location of the first estimation of mirror device.Meanwhile, the sun penetrates cloud irradiation.Now
Close to noon, and therefore the sun irradiates in south.But solar tracking mirror system is towards the north.
First and second optical sensors can not collect the direct incident illumination from the sun, because control unit North facing
Side.But, the 3rd optical sensor is towards south, and therefore measures the 3rd light intensity directly collected from the sun.
3rd light intensity thus more than according to respectively by control unit first and second optical sensors measure first
The intensity threshold that light intensity or the second light intensity determine.Therefore control unit determines mirror according to three light intensities
The optimal location of subset, the optimal location of mirror device is the position of the 3rd optical sensor, i.e. shows at this
Example is south.The optimal location that first estimates is corrected as this optimal location and mirror by mirror device subsequently
Towards south, i.e. region be directly facing the sun.Therefore the use of the 3rd sensor avoids mirror device and is in mistake
Position.If it addition, daylight is excessively dull so that three optical sensors can not measured light intensity, the then sun
Following reflex mirror system freezes to be possible to.When following the trail of operation and recovering after freeze-off time, the 3rd light
The use of sensor guarantees that the intensity that the optimal location that first estimates is corrected as reflection by mirror device is bigger
The optimal location of mirror device, the new position of the sun after this optimal location instruction freeze-off time.This maximizes
The efficiency of solar tracking mirror system whole day.
In this way, the efficiency of solar tracking mirror unit whole day is maximized.Even if the sun is covered by cloud,
As long as three optical sensors can measured light intensity, solar tracking mirror system is the most all the time towards being reflected towards sky
The direction that the sunlight intensity of window is maximum.Which ensure that worker and/or the light of habitant of building belonging to skylight
According to experience.The simple realization of three optical sensors in control unit does not require to use additional time sensing
Device, position sensor or programmable unit, which ensure that compactedness that control unit designs and ensure that letter
Clean property.Solar tracking mirror system realize cost and use cost is also minimized because can use with
The 3rd optical sensor that first and second optical sensors are identical.
According to an alternative embodiment, it is described that described mirror device is further adapted into when in described light intensity
3rd light intensity is more than the described first light intensity twice in described light intensity or more than described second light intensity twice
Time by described first estimate optimal location be corrected as described optimal location.
The position of mirror device only more than the twice of the first light intensity or is more than the second light intensity in the 3rd light intensity
Twice time be corrected as optimal location.In this case, intensity threshold is therefore equal to the first light intensity
Twice or the twice equal to the second light intensity.Alternatively, the position of mirror device is only equal in the 3rd light intensity
Or it is corrected as optimal location when the twice more than the first light intensity or the twice equal to or more than the second light intensity.
In this way, it is to avoid for the error detection of the optimal location of mirror device.It is true that intensity threshold quilt
Select and measure the of the reflection corresponding to daylight so that control unit can be dependably distinguished from the 3rd optical sensor
The 3rd light intensity corresponding to direct daylight actually measured by situation and the 3rd optical sensor of three light intensities
Situation.Such as, the light intensity of 10000lx all measured by the first and second optical sensors, and the 3rd light senses
The light intensity of 15000lx measured by device.Difference between 10000lx and 15000lx is not enough to allow control unit
Determine that the optimal location of mirror device is different from the optimal location of the first estimation.There is the 3rd optical sensor to measure
The risk of the reflection of daylight.Such as, if the light intensity of 10000lx all measured by the first and second optical sensors
Degree, and the light intensity of 20000lx measured by the 3rd optical sensor, then the 3rd light intensity and the first light intensity or
Difference between second light intensity is large enough that control unit determines mirror according to the 3rd light intensity exactly
The optimal location of subset.In this way, the determination of the optimal location of mirror device becomes accurate and reliable,
And do not affected by the interim cloud of interim dull sunlight intensity.
According to an alternative embodiment, in described protective shield corresponds to subregion shadowing elements, described subregion
Shadowing elements is adapted on first optical sensor or the second optical sensor of described three optical sensors produce the moon
Shadow.
First optical sensor and the second optical sensor are occluded one another by protective shield, protective shield and reception reflection
The axis alignment in the direction of light.It is anti-that first optical sensor and the axis with the direction of the light receiving reflection align
That protects that distance between the screen axis equal to the second optical sensor with the direction of the light receiving reflection aligns is anti-
Protect the distance between screen.In other words, the protective shield that the axis with the direction of the light receiving reflection aligns is with described
First optical sensor and described second optical sensor are equidistant.
The optimal location of the first estimation of mirror device senses by controlling the first light in three optical sensors
Difference (institute between the light intensity that the second optical sensor in the light intensity of device measurement and three optical sensors is measured
Stating three optical sensors is the measurement to the intensity incided on mirror) determine.First and second light sensings
When the difference of the light intensity between device is not region be directly facing the sun by mirror device, subregion shade element is first
Or second the shadow that generates on optical sensor cause.Therefore the optimal location of the first estimation of mirror device is
Wherein subregion shade element is not in the first optical sensor or the mirror device of the second optical sensor upslide projection
Position.In other words, when mirror device is placed according to the first optimal location estimated, the first light sensing
Second light intensity of the incident illumination that the first light intensity of the incident illumination that device is measured is measured equal to the second optical sensor.
According to an alternative embodiment, control unit is further adapted into:
The optimum that instruction described first is estimated is determined according to described first light intensity and described second light intensity
The reference value of position；And
The optimum reference value indicating described optimal location is determined according to described 3rd light intensity.
When the fiducial value of the light intensity measured based on the first and second optical sensors exceedes the limit value of pre-determining,
Control unit determines the optimal location of the first estimation.This fiducial value is surveyed equal to based on the first and second optical sensors
The value of the difference of the light intensity of amount is divided by the sum of the light intensity measured respectively based on the first and second optical sensors
The absolute value of value.This fiducial value appears to be for determining when that should seek more preferable first estimates
The good benchmark of excellent position.Have been found that this pre-determining limit value preferably 0.01 and the most only comparing
The optimal location of the first estimation is determined when value is more than 0.01, because good location can be obtained at this value, but
It is that of avoiding excessive the reorientating with energy expenditure.Control unit is determined by according to first and second
The reference value that the light intensity that optical sensor is measured calculates determines the optimal location of the first estimation.This reference value is entered
One step is preferably equivalent to the value of the difference of light intensity based on the first and second optical sensors measurements and based on first
The business of value of the sum of the light intensity measured with the second optical sensor.Fiducial value is actually the absolute of this reference value
Value.The value of the difference of light intensities based on the first and second optical sensors measurements is preferably by the first and second light
Sensor determines at least two difference of at least two pairs of light intensities of the measurement of different time.Based on the first He
The value of the sum of the light intensity that the second optical sensor is measured preferably passes through the first and second optical sensors in difference
At least two of the light intensity of the measurement of time and determining.For and with difference, use identical corresponding
The light intensity measured.Such as, the basic light intensity simultaneously measured by the first and second optical sensors is recorded to
Just meansigma methods is calculated.Preferably at least 2 (more preferably 5) of corresponding first and second light intensities
Value by equal times measure with record with calculate corresponding number of times (preferably 5 times) and with difference, wherein
Difference is consistently equal to the first light intensity and deducts the second light intensity, the most respectively calculating and the meansigma methods with difference so that
Obtain meansigma methods (preferably 5) and the meansigma methods (preferably 5) of difference of sum.Preferably, if
Excellent reference value is more than 0, then mirror device turns clockwise based on reference value, if optimum reference value is less than 0,
Rotate the most counterclockwise.As long as fiducial value exceedes the limit value of pre-determining, mirror device just corrects the according to reference value
One position estimated, as long as fiducial value is less than the limit value of this pre-determining.As long as fiducial value is more than pre-determining
Limit value (preferably 0.01), mirror device is revolved by the motor controlled by control unit according to this reference value
Turn.If the limit value of this fiducial value e.g., less than pre-determining after this rotation of mirror device, then this follows
Ring terminates.After the measurement of every 2 times (more preferably 5 times) first and second light intensities, control single
Unit receives the 3rd light intensity of the 3rd optical sensor and the 3rd light intensity based on the 3rd optical sensor measurement
Determine optimal location.In this way, mirror device first estimation optimal location and optimal location really
Surely it is accurate and reliable.
According to an alternative embodiment, described mirror device is further adapted into rotation and reaches described optimum reference
Value, thus the optimal location that described first estimates is corrected as described optimal location.
When the 3rd light intensity is equal to or more than determining according to the first light intensity in light intensity or the second light intensity
Intensity threshold time, control unit determines that optimum reference value is to be corrected as optimum by the optimal location that first estimates
Position.Mirror device rotates subsequently and reaches the optimum reference value indicating this optimal location.When the 3rd light intensity is less than
During the intensity threshold determined according to the first light intensity in light intensity or the second light intensity, control unit determines
One optimal location estimated is optimal location.Which ensure that the efficiency of solar tracking mirror unit whole day is by
Bigization, as long as because three optical sensors can measured light intensity, solar tracking mirror system face the most all the time
To the direction that the sunlight intensity being reflected towards skylight is maximum.

The control position based on the sun of the position of son.
The method according to the invention optimizes the position of solar tracking mirror system, and described solar tracking reflects
Mirror system includes three optical sensors arranged according to triangle manner.Each optical sensor by protective shield that
This separates.According to the present invention, the 3rd optical sensor is employed to ensure that mirror device is in errors present never,
The direction that i.e. sunlight intensity of the seizure of mirror device whole day object mirror equipment all the time and reflection is maximum.Such as,
At sunset, solar tracking mirror system west.At sunrise and be enough to allow at sunlight intensity
During three optical sensor measured light intensity, according to first and the measured by the first and second optical sensors respectively
Two light intensities determine the optimal location of the first estimation of mirror device, and solar tracking mirror system is still simultaneously
West.But, at sunrise, the sun rises in the Orient, and the sun the most such as deviating from west chases after
Track mirror system rotates 180 °.In other words, true when solar tracking mirror system not region be directly facing the sun
The optimal location of the first estimation of horizontal glass.The 3rd optical sensor blocked by other two sensors can be surveyed
Flow control three light intensity.Consider that this 3rd light intensity is to further determine that the optimal location of mirror device.True
On, when the 3rd light intensity is more than the intensity threshold determined according to the first light intensity or the second light intensity, the 3rd
Optical sensor provides the instruction of the position that there is the preferred mirror device of optimal location than the first estimation.Change
Yan Zhi, the 3rd optical sensor provide instruction to exist sunlight intensity that mirror device catches and reflect will ratio the
The mirror device that at one optimal location estimated, sunlight intensity that mirror device caught and reflected is bigger is
The information of excellent position.Such as, at sunrise, when the sun comes up in the east and when solar tracking reflecting mirror system
Unite still west time, the of the light intensity in the east that instruction is risen measured towards the sun by the 3rd optical sensor
Three light intensities.When this 3rd light intensity more than intensity threshold time, the optimal location of mirror device be therefore by
The position that 3rd optical sensor is limited.Intensity threshold such as corresponding to the first light intensity and the second light intensity it
Between maximum.Therefore the optimal location of mirror device is determined and is different from the optimum position of the first estimation
Put.First optimal location estimated is corrected to optimal location.On the other hand, when the 3rd light intensity is less than root
During the intensity threshold determined according to the first light intensity or the second light intensity, the 3rd optical sensor provides and there is not ratio the
The instruction of the position of the one preferred mirror device of optimal location estimated.Intensity threshold is such as corresponding to first
Maximum between light intensity and the second light intensity.In other words, when the 3rd light intensity is less than according to the first light intensity
During the intensity threshold that degree or the second light intensity determine, the 3rd optical sensor provides instruction to there is not mirror device institute
Catch and the sunlight intensity of reflection will be caught than mirror device at the first optimal location estimated and reflect
The information of optimal location of the bigger mirror device of sunlight intensity.The optimum position of the first estimation of mirror device
Therefore put the optimal location with mirror device is identical.Alternatively, when the 3rd light intensity in described light intensity
Degree is equal to or more than the intensity threshold determined according to the first light intensity in described light intensity or the second light intensity
Time by described first estimate optimal location be corrected as described optimal location.
According to the present invention, the 3rd optical sensor is employed to ensure that mirror device is in errors present never, i.e.
The direction of the sunlight intensity maximum of the seizure of mirror device whole day object mirror equipment all the time and reflection.Such as, exist
At sunrise, the sun may be covered by cloud but sunlight intensity is the most sufficiently large to allow solar tracking reflecting mirror system
System work.Solar tracking mirror system in fact towards east, but owing to being broken sky, the therefore sun
The search of following reflex mirror system reflexes to the intensity of the light in skylight more than towards the of mirror device during east
One optimal location estimated.The intensity of solar tracking mirror system mark daylight is more than towards north during east
The point of side, and solar tracking mirror system is it is thus determined that the north is mirror device the first optimum estimated
Position.The 3rd light intensity that 3rd optical sensor catches is less than according to respectively by the first and second of control unit
The intensity threshold that first light intensity of optical sensor measurement or the second light intensity determine.Mirror device is therefore by it
Position is corrected as the optimal location of the first estimation of mirror device.Meanwhile, the sun penetrates cloud irradiation.Now connect
It is bordering on noon, and therefore the sun irradiates in south.But solar tracking mirror system is towards the north.The
One and second optical sensor can not collect the direct incident illumination from the sun, because control unit is towards the north.
But, the 3rd optical sensor is towards south, and therefore measures the 3rd light intensity directly collected from the sun.The
Three light intensities thus more than according to respectively by control unit first and second optical sensors measure the first light
The intensity threshold that intensity or the second light intensity determine.Therefore control unit determines mirror according to three light intensities
The optimal location of equipment, the optimal location of mirror device is the position of the 3rd optical sensor, i.e. in this example
In be south.The optimal location that first estimates is corrected as this optimal location and mirror face by mirror device subsequently
South, i.e. region be directly facing the sun.Therefore the use of the 3rd sensor avoids mirror device and is in error bit
Put.If it addition, daylight excessively dull so that three optical sensors can not measured light intensity, then the sun chases after
Track mirror system is freezed to be possible to.When following the trail of operation and recovering after freeze-off time, the 3rd light passes
The use of sensor guarantees that the optimal location that first estimates is corrected as the bigger mirror of intensity of reflection by mirror device
The optimal location of subset, the new position of the sun after this optimal location instruction freeze-off time.This maximises
The efficiency of solar tracking mirror unit whole day.
In this way, the efficiency of solar tracking mirror unit whole day is maximized.Even if the sun is covered by cloud,
As long as three optical sensors can measured light intensity, solar tracking mirror system is the most all the time towards being reflected towards sky
The direction that the sunlight intensity of window is maximum.Which ensure that worker and/or the light of habitant of building belonging to skylight
According to experience.The simple realization of three optical sensors does not require to use timer, the position sensor added
Or programmable unit, which ensure that compactedness that solar tracking mirror system designs and ensure that succinct
Property.Solar tracking mirror system realize cost and use cost is also minimized, because can use and the
One threeth optical sensor identical with the second optical sensor.
