Position of sun is tracked and the mode of steering engine is driven to be explained in detail below:
There are two types of the sunlight trace modes of the present invention, first, Photoelectric Detection tracks pattern, by the instant of sunlight
It detects to be tracked;It is another then be regard daily motion trajectory track pattern, i.e., calculate the sun by presetting function
Orientation is fixed rotation and is tracked, in order to improve tracking quality, before two kinds of tracking patterns be combined to sunlight
Be tracked, i.e., fine day when, intensity of illumination is sufficient, and pattern is tracked using Photoelectric Detection, and the intensities of illumination such as cloudy day are insufficient, depending on
Daily motion trajectory track pattern, to generate higher tracking efficiency.Using to Photoelectric Detection tracking pattern and regarding daily motion
The binding pattern of both trajectory track patterns advantage tracks pattern when fine day using Photoelectric Detection, uses photosensitive sensor, profit
Relatively judge solar azimuth with the voltage difference of photosensitive sensor, cooperation servos control mechanical part chases after sunlight immediately
Track, the pattern receiving efficiency are high;Enter rainy days and regard daily motion trajectory track pattern, was calculated at that time too by presetting function
The azimuth of sun and elevation angle are tracked, and are determined workflow progress, are daytime this moment with photosensitive sensor system detectio
Or at night, if it is at night, system is not just run;If it is daytime, priority is chased after with Photoelectric Detection tracking
Track, but when the luminous energy that photosensitive sensor receives is too small, such as rainy weather, SCM system can be transferred to setting automatically and regard
Daily motion trajectory model deflects to control steering engine, then starts timing and changes azimuth from external clock read access time, ensure that
The full-time workflow of system receives and stablizes.The advantages of present invention incorporates Photoelectric Detection and regarding day system, learn from other's strong points to offset one's weaknesses,
Keep total system operation more accurate and stablizes.
The present invention drives the scheme of steering engine, each angle of steering engine to correspond to different control pulsewidth and assume steering engine initial angle
Be 0 °, when providing the pwm control signal that pulsewidth is 2500ms, the period is 20ms, steering engine with the speed of 400 °/s rotate to
180 °, rotational time, which is data of 0.45s. configurations, can generate the pwm signal that pulsewidth is 2500ms, the period is 20ms, rudder
Machine, which with most fast rotating speed turns to corresponding angle and now control, to be required to become steering engine to go to 180 ° by 0 ° with the speed of 60 °/s, is at this moment used
General PWM signal generator needs to configure repeatedly, the pwm signal pulsewidth of each cycle by 0 ° of corresponding 500ms linear change extremely
180 ° of corresponding 2500ms, specific algorithm are as follows
If steering engine rotational time is t, pwm control signal cycle T is 20 × 10-3S, 0~180 ° of corresponding pulsewidth is 0.5 ×
10-3~2.5 × 10-3S, initial angle α, termination point β, then:
Need the PWM cycle number c=t/T generated
Initial angle corresponds to pulsewidth:
Initial angle corresponds to pulsewidth:
Each cycle pwm signal changes pulsewidth:(Tτ>0 indicates that angle increases, Tτ<0 indicates that angle reduces)
The above Tα,Tβ,TτUnit be all s, need to be converted into the counting pulse of TIMER when configuring PWM signal generator
Number.It can be seen that using common PWM signal generator need to configure c times when steering engine rotating speed controls, steering engine parameters are
Know, steering engine initial angle is locked, if steering engine need to turn to certain angle, need to only calculate what entire control process needs generated
PWM cycle number c and each cycle pwm signal variation pulsewidth Tτ.
1. tracking pattern for Photoelectric Detection and servo driving being explained in detail:
Photoelectric Detection tracing mode is a kind of on-demand system, is determined at any time according to the change of the size of sunlight and incidence angle
The direction of reception is that photosensitive sensor is made to receive sunlight first, is then converted into as electrical signal for transmission to microcontroller, by list
Piece machine decides whether to change receiving angle direction, then sends out instruction, control steering engine operation, turn to suitable orientation
Angle.
1.1. Photoelectric Detection tracing model scheme
Determine that intensity of illumination reaches the degree of startup whole system by photosensitive sensor, it is then cloudy, fine day by detection again
Photosensitive sensor detects intensity of illumination, judges whether to reach the requirement for starting Photoelectric Detection tracking pattern, if up to requiring, by sensing
Device incudes sunlight incident direction immediately, and the electric signal of generation sends microcontroller to after being amplified by operational amplifier, then by microcontroller
Control steering engine operates to change the direction of clothes-horse, to reach pre-provisioning request.
It is the system for incuding sunlight incident direction immediately by sensor, is made of 4 photosensitive sensors, this 4 photosensitive biographies
Sensor in order to the appropriate irradiation for receiving sunlight and is avoided by certain distributing installation on a disk
Meaningless interference, it is also necessary to which the hollow cylinder cover on the set of the outside of disk does the use that screening receives sunlight, cylindrical sleeve top
It is upper that there are one loopholes.Sunlight can be caused to penetrate on inner wall if cylinder cover is too long, system can be mistakenly considered cloudy day or even evening
On, gently then lose reception energy efficiency like that, seriously may result in system switching too frequently and it is chaotic, or even crash;Too
Short and can all receive at any time, system has no way of selecting, and is also easy confusion.This 4 photosensitive sensors are in cross distribution, each photosensitive biography
Certain interval is all kept between sensor and its that nearest photosensitive sensor, occupation of land side, range of receiving become every having obtained too dilute
Relative narrowness does not receive;Every having obtained too close and being susceptible to reception confusion, i.e., all receives or all do not receive, and
Light reflection refraction after can all have large effect.
The outer rim of cylinder cover will slightly more greatly than the diameter of disk, and then that 4 photosensitive sensors are by certain point
Cloth is mounted on above disk, in order to the appropriate irradiation for receiving sunlight and avoids meaningless interference, it is also necessary in circle
The hollow cylinder of outer surface cover of disk does the use that screening receives sunlight, also to add a loophole on cylindrical sleeve top.Wherein,
We set the distance between 4 sensors around and are taken as 6mm less times greater than their diameter.
Height H for the cylinder addressed, calculation are as follows:Assuming that incident angle is not vertical at this time for the sun,
One tiltangleθ can calculate the right height of cylinder cover by this θ as needed.Therefore, best situation is at 15 points
In clock, the distance x that sunlight moves on cylinder cover inner disk is not less than the diameter 2.5mm of 0.5 photosensitive sensor, but also not
More than 1.5 times photosensitive sensor diameters add gap=13.5mm of 6mm preferably.Following formula can be obtained:
Again because the angle, θ of 15 minutes sun movement is almost a definite value, i.e.,:180 ° of sun movement on 12 hours daytimes,
Both 15 ° of movement in 1 hour, so approaching and moving 4 ° for 15 minutes, it may thus be appreciated that road 36mm≤H≤193mm.Therefore consider
Cylinder is unsuitable excessively high, and avoids occurring light beam just at every 15 minutes as possible being moved in the gap between two sensors,
Take cylinder H=50mm.
1.2. the scheme that photoelectric tracing is combined with steering engine
The present invention needs to be detected the light intensity of four direction, is divided into left and right light intensity separate-blas estimation and upper and lower light intensity deviation
Detection.Microcontroller acquires the voltage value of four road photoelectric sensors, is stored in corresponding variable after being converted into digital signal.Each pair of
The voltage difference AD conversion of photoelectric sensor is converted into corresponding pulse week at digital signal by the formula of above-mentioned servo driving
Phase signal, driving servo motor rotation then continues to acquire signal to reduce deviation, when within deviation range permission, light
Electric tracing stops, to achieve the purpose that location tracking.Photoelectric tracking can achieve the purpose that be accurately positioned position of sun relatively.
2. for being explained in detail depending on daily motion trajectory track pattern and servo driving:
Depending on daily motion trajectory track, first have to judge the intensity and angle of sun incidence according to local latitude, longitude,
Then receiving angle is calculated again, writes program, then from read access time on external clock chip, calculate the sun now at what
How many orientation and the preceding orientation upper angle once determined differ, and the direction that should currently control motor rotation is determined with this
And angle.
2.1. daily motion trajectory track model scheme is regarded
It is to determine that intensity of illumination reaches the degree of startup whole system by intensity of illumination detection photosensitive semiconductor first, then
Detect whether intensity of illumination reaches the requirement for starting Photoelectric Detection and tracking pattern by the photosensitive sensor for detecting rain or shine day again, if
Cloudy day then switchs to regard daily motion trajectory track pattern, and the instant time is read from clock chip by microcontroller, is calculated with the interior function that sets
Sunny angle, control steering engine are operated by calculated track, track the sun.
The running orbit of the sun is indicated with two parameters in a three-dimensional level:Sun altitude and too
Positive azimuth.Sun altitude:Sun altitude refers to from the center direct projection of the sun to local light and the ground horizontal plane angle,
Its value changes between 0 ° to 90 °, and the sun just out and is just considered 0 ° when fall, then when high noon 12, vertically
Object be considered 90 ° when can't see shadow.Solar azimuth:Orientation where solar azimuth, that is, sun, refers to sunray
Projection on ground level and local meridianal angle, can approximately see the straight line being erected on ground as in daylight
Lower shade and positive angle in the south.Azimuth is zero with due south direction, is negative by south east, is just, as the sun exists by south orientation west
Positive east, then shadow is exactly in positive west, azimuth is just -90 °, and in positive west, shadow is exactly in positive east, then orientation
Angle is exactly 90 °.
Had in 1 year 365 days, if corresponding section [0,π], there is a day angle:
RnIt is taken as the date sequence in year, then n can do 1 taking January 1, and December 31, which took, does 365.
Following formula is reused, declination δ is indicated with radian:
δ=0.00689-0.39951cos θ0+0.07208sinθ0-0.0068cos 2θ0+0.0009sin2θ0-
0.00269cos 3θ0+0.00151sin3θ0
Solar hour angle is taken as W, is calculated with following formula:
The W=true solar times (hour) × 15-180;
W units are degree in formula, and 15 indicate to be equivalent to 15 ° of hour angles per hour
When true solar time=Beijing+the ÷ 60+ time differences of (local longitude -120) × 4
The time difference (radian)=
0.000076+0.001869cosθ0-0.032086sinθ0-0.014616cos 2θ0-0.04085sin2θ0
The time difference (the hour)=time difference (radian) × 12 ÷ π
If sun altitude and azimuth are respectively θhAnd θp, geographic latitude D has formula
sinθh=sinDsin δ+cosDcos δ cosW
Pass through introduction to above sun altitude and solar azimuth and correlation formula, it can be appreciated that only
It needs to be determined that longitude and latitude, also having time, can then calculate sun specific location at that time by above formula, and
In year, this value is to determine and uniquely.Because to realize the mean sun side of instant computing in the present system
Parallactic angle degree, and the track that steering engine operation drives the clothes-horse tracking sun is controlled, it can realize this function, monolithic with microcontroller
The function performance of machine is very powerful, measures longitude and latitude numerical value by GPS, the instant time obtains by reading clock chip.
So the mean sun position of random time, angle value can obtain.
2.2. it regards and day tracks the scheme combined with steering engine:
After initially entering sun angle tracking pattern, current time is obtained from the theres clock chip DS1302, from GPS module
Local latitude and longitude information is obtained to calculate sun altitude at this time and azimuth in conjunction with preset formula, azimuth is led to
It crosses calculating and is converted into the driving corresponding pulse-period signal of steering engine, driving servo motor rotation then continues to acquire signal, until
When reaching in specified deviation section, tracking stops, to achieve the purpose that location tracking, every 15 minutes cycle above-mentioned steps.
The preferable specific implementation mode of the above, only the invention, but the protection domain of the invention is not
It is confined to this, any one skilled in the art is in the technical scope that the invention discloses, according to the present invention
The technical solution of creation and its inventive concept are subject to equivalent substitution or change, should all cover the invention protection domain it
It is interior.
