It sets.
Background technique
Solar energy is a kind of low-density, intermittence and the clean energy resource changed at any time with the variation in space.The sun with
The method of track is generally divided into two classes, and one kind is the position by the photoelectric sensor real-time detection sun over the ground, controls lighting equipment
To the Passive Track of day angle;Another kind of is to calculate the position of the sun over the ground in real time according to astronomical mathematics formula, controls daylighting
Active tracking of the device to day angle.
The precision of photo-electric passive tracking itself is higher, but has the shortcomings that in field of solar energy utilization following: the cloudy day too
Positive irradiation level is weaker, and photoelectric sensor is difficult to respond the variation of light, and tracking result is unsatisfactory;In cloudy weather
In, sun itself by cloud layer cover or the aerial somewhere in day due to cloud layer is thinning and when there is relatively bright hot spot, photo-electric
Passive tracking may be such that lighting equipment malfunctions, or even can start suddenly and cause accident.
Active tracking by calculate the sun on high in position determine, give longitude, latitude, the height above sea level of observation point
Height and current standard time, the sun on high in position can be calculated by astronomical mathematics formula, be embodied in
Using the horizontal system of coordinates of observation point as reference, the sun is relative to the elevation angle of observation point horizontal plane and relative to the positive north and south of observation point
The azimuth in direction.In the case where determining local longitude, latitude, height above sea level and time, the tracking essence of sun tracker

Itself is generally there are machine error, and if pitching rotary shaft and orientation rotation axis are there are nonopiate declination error, sunlight works mirror surface
There are not parallel declination errors for opposite pitch axis, and there are null angle errors etc. for pitching rotary shaft and orientation rotation axis.
If the accumulated error that installation error as described above and all kinds of machine errors are formed is excessive, solar tracking will be made
The tracking accuracy of device is difficult to ensure.How to reduce or eliminate the accumulated error that installation error and machine error are formed be the sun with
The main problem that track device faces.This also promotes current sun tracker to pass mostly using expensive High-precision angle
Sensor, laser ranging, CCD imaging, gyrotheodolite etc. eliminate real north using closed-loop control system and mechanical accumulation miss
The cost of sun tracker is significantly increased in difference, and installation and debugging are complicated.
