Time interval is usually 1 second to 30 minutes, and typically 1 minute.

Step 13, when reaching scheduled time point, under the control of controller module, stop or start the solar tracking Device.

Detailed process is as follows when as shown in figure 8, the active sun tracker being worked in day operating mode:

It step 1, is that the direction z is established too using the horizontal plane in the sun tracker location as x/y plane, plumb line direction The positive position horizontal system of coordinates, geographical East and West direction and geographical north-south are respectively the direction x and the direction y of x/y plane.

Step 2, controller module reads present clock information and local longitude, latitude by geography information and clock module Degree and elevation information calculate in the position of sun horizontal system of coordinates of the sun in step 1 at this time according to these information read Position of sun vector.To under day operating mode, this position of sun vector is the normal line vector of mirror surface sunlight work mirror surface 5.

Step 3, the position of sun vector in step 2 is decomposed into sunlight work mirror surface 5 in the position of sun horizontal system of coordinates In elevation angle and azimuth.

Step 4, controller module issues the first proportional pulse signal, according to side according to the elevation angle that step 9 determines Parallactic angle issues the second proportional pulse signal, and the first pulse signal and 3 collective effect of the first zero position switch control first motor Drive module 1 turns to corresponding angle, and the second pulse signal and 4 collective effect of the second zero position switch control the second motor driven Module 2 turns to corresponding angle.
