Detailed description of the invention
Below in conjunction with the accompanying drawings technical scheme is described in further detail:
Fig. 1 is EO-1 hyperion instrument equipment and sunlight plane of incidence, and sensor constitutes a plane of vision, sunlight incidence conduct
Another one plane, rotating disk design ensures that sun plane of incidence is always 135 ° with the φ in Instrument observation plane both Fig. 5, by mistake
Difference is at positive and negative 2.5 degree.
Fig. 3 is the detection partial schematic diagram of photoelectric tracking.In order to reach cost-effective and effectively realize solar azimuth
Following the tracks of, this device utilizes the sciagraphy of easy structure to realize azimuthal tracking.
In Fig. 3, great circle is a disk, and 13, top roundlet and one, lower section roundlet are photoconductive resistance, central black roundlet
Vertical view pattern for cylindrical mark post.Article two, dotted line is that photoconductive resistance border (actual suitable distance outside border) is to cylinder mark post
Angle a at center.Black arrow is cylinder projection under sunray.
First, according to the definition of solar azimuth: sunray projection on ground level and the meridianal angle in locality,
Then can approximate the angle regarding the straight line established on the ground shade in the sun as with direction, due south.And project demand be with
Sunlight plane of incidence remains certain angle φ, then can control to keep certain by the shade of cylinder rower bar
Angle.
Owing to project demand precision is within positive and negative 2.5 degree, it is determined that angle A is 5 degree, device purpose is: rotating circular disk
It is directly over shade is projected on roundlet, according to accuracy range requirement, then when the photoconductive resistance having shade to be projected in surface
On, i.e. it is believed that reached requirement, i.e. remain certain angle φ with sunlight plane of incidence.
How to implement: in figure, 12, top black roundlet plays the effect demarcating the number of degrees, and each roundlet is represented as 5 degree,
By roundlet above center clockwise, scale counterclockwise is as 5,10,15,20,25,30.As long as above Zheng Zhong on roundlet
There is shade, then it is assumed that be satisfactory (solve shade and simultaneously fall in roundlet and the situation of side black roundlet above center),
Need not adjust.As long as not having shade above Zheng Zhong on roundlet, then to adjust, which roundlet detection shade is projected on, then up time
Pin or counterclockwise rotation angle corresponding to roundlet.If shade simultaneously falls on two black roundlets, turn average angle.
How to differentiate: photoconductive resistance module can detect whether intensity of illumination reaches setting value, then output 0 or 1, by the left side
Six photoconductive resistance data module outfans are connected to the P1 group port of single-chip microcomputer, and six, the right is connected to the P0 group end of single-chip microcomputer
