Breath combines azimuth γ of the heliostat (100) relative to central tower (1) bottom endDAnd inclination alphaDWith standard picture information comparison, obtain
The elevation angle α of the sun at this timeSWith azimuth γS；Center processor (632) calculates the adjustment information number that heliostat (100) needs
According to；Specific calculating process is as follows：
On the basis of plane where the heliostat field (2), secondary light condensing device (5) receiving point on central tower (1) top is flat to this
The vertical direction in face establishes coordinate system for Z axis forward reference；The coordinate of the secondary reflection mirror receiving point A on central tower if (1) top
For (0,0, h), the coordinate of light sensor (61) central point R is (xR,yR, 0), then the unit vector of coordinate origin O to sun S
It represents The unit vector of point R to sun S representsIt is arrived with point R
The unit vector of receiving point A representsIt is represented by：
WithIn the plane formed,WithAngle be denoted as β, then have
Set solar eyepiece unit normal vector asThen from the add operation of vector：
Then
Remember current heliostat unit normal vectorVector be expressed as
Abbreviation P1, P2, P3, P4, and abbreviation result and formula P5 are compared, so that it is determined that the adjustment information data of heliostat (100)；
S3：The adjustment information for calculating gained is transferred to center by the center processor (632) of several light determining devices (63) respectively
Processor (200), central processing unit (200) extract median, assign instruction to the first hoist (36), the second hoist
(37) and motor (4)；
