Positive energy orientation system in a dormant state, does not implement angular adjustment.
Before the angle for adjusting solar opto-electronic board, it is necessary to sunny current elevation angle and azimuth are calculated, in conjunction with Fig. 3 institute
Show, Computing Principle of the invention derives from following calculating process:
1. declination angle:
The equatorial plane and angle≤ecliptic plane of sunray direction of illumination and 27 points of angle≤23 degree of the equatorial plane
(23.45 degree);
(sunray direction of illumination: the direction that earth center and solar core line are formed)
Summer solstice (6/21,6/22), declination angle was 23 degree 27 points when the sun is located at the tropic of cancer in the Northern Hemisphere, the autumn in the Spring Equinox
Divide (3/21,3/22,9/22,9/23) when the sun is located at equator, declination angle is 0 degree, and Winter Solstice, (12/22,12/23) was when sun position
When the tropic of Capricorn, declination angle is -23 27 points of degree.
The rough calculation formula in declination angle:
Declination angle δ=23.45*sin ((N-80)/370.0*360)
(N is the number of days from New Year's Day).
Such as:
The Spring Equinox day substitutes into, and (N-80)/370.0*360 is approximately equal to 0 degree, and declination angle is about 0 at this time;
The Autumnal Equinox day substitutes into, and (N-80)/370.0*360 is approximately equal to 180 degree, and declination angle is about 0 at this time;
2. solar hour angle:
Hour angle (about for 24 hours) is equivalent to the sun on celestial sphere figure around tour by earth rotation one week, this and warp pair
Answer, averagely get off, one hour 15 degree, a warp is separated by 15 degree.
Hour angle calculation formula are as follows:
Hour angle Ω=15* (t-12)
(t is the local time).
Such as:
When local 12 noon, hour angle 0, the sun is located at when the surface of mainthread;
At local midnight 12, hour angle 180, the sun is located at when the underface of mainthread;
Local time refers to that true solar time, Beijing time are not the local time, and if conversion, Xinjiang region needs to postpone
1 hour is located at Dong7Qu.
3. solar elevation
The angle of sunray and ground level is known as solar elevation, range [- 90 degree, 90 degree]
Under normal circumstances, between the tropic of cancer and the Arctic Circle, at the local time 12, solar elevation is maximum, and 24 points
When, solar elevation is minimum.
Sin (elevation angle H)=cos Ω cos δ cos Φ+sin δ sin Φ
(Ω is solar hour angle;δ is declination angle;Φ is latitude)
4. solar azimuth
The angle in projection line of the sunray on ground level and ground level due south direction is known as solar azimuth, range [-
180 degree, 180 degree].
Under normal circumstances, between the tropic of cancer and the Arctic Circle, at the local time 12, solar elevation is 0 degree, 24 points
When, solar elevation is 180 degree/- 180 degree.
Sin (azimuth A)=(- sin Ω cos δ)/cosH
(Ω is solar hour angle;δ is declination angle;H is elevation angle)
It is learnt, solar elevation and azimuthal calculate can be abstracted from above are as follows:
(H, A)=f (DT, Vx, Hy)
(H is solar elevation;A is solar azimuth;DT is current time (containing the date);Vx is geographic logitude;Hy is ground
Manage latitude.)
The latitude and longitude information provided by the included GPS module of host GPS module or system, STM32 control mainboard can be with
DT, Vx, Hy are calculated, solar elevation and azimuth, the normal side of calculated result and current solar energy equipment can be calculated
To comparing, difference is obtained, output order adjusts motor rotation, reaches the mesh that control solar energy receiving device adjusts the angle
's.
To sum up, this system can be used as system access that one is completely independent operation to Internet of Things network, pass through zigbee
Agreement accesses wireless privately owned zigbee communication network, and backstage Internet of Things main-machine communication, to form one of Internet of things system
Standalone module, and location information and environmental parameter are obtained by Internet of Things host, it is transmitted to STM32 control mainboard, STM32 control
Mainboard calculates solar azimuth and elevation angle automatically, then respectively drives two motors while operating, adjust automatically solar energy
The angle of electro-optical package reaches the optimal utilization rate of solar energy;
Under haze, sleet weather, solar energy receiving device is almost without energy conversion efficiency, therefore, can pass through
STM32 control mainboard receives and analyzes environmental parameter, allows system to be in suspend mode shape body under specific weather condition, does not implement to adjust;
The included GPS module of system is accessed in the form of hot plug, is causing system that can not access Internet of Things because of cause specific
When location information is provided, when Internet of things system has GPS data to be passed to, the GPS module, saving construction cost cost can be saved;
Exceed the maximum position in order to prevent, installs limit switch in extreme position, limit signal is input to and is controlled with STM32
Mainboard processed, the switch protection signal as motor.
