The coordinate that rotatable support frame control module obtains rotatable support frame infield by GPS interface/reception unit is joined Number, and the astronomical constants that the sun being converted into rotatable support frame infield runs, open angle A when the sun rises to morning1Time, can revolve Turning support control module and wake up current detection module up, current detection module starts to detect the defeated of photovoltaic array or current detecting unit Go out current value, when current detection module detects that output current value reaches I1Time, solar tracking system starts to follow the tracks of sun fortune OK, if output current value is not up to I1, continuation is returned/wind resistance guard mode wait at night by solar tracking system, until electric current Detection module detects that output current value reaches I1, solar tracking system starts to follow the tracks of the sun and runs;
Normally follow the tracks of in running at solar tracking system, when current detection module detects that output current value reduces To I2Time, rotatable support frame driver is normally followed the tracks of operation by stopping rotatable support frame, and is driven rotatable support frame to be back to Return/wind resistance guard mode night;
Angle A is returned when the sun runs to night2Time, solar tracking system starts to return, returns/wind resistance guard mode to night, Current detection module quits work.
Further, normally following the tracks of in running at solar tracking system, control module periodically compares photovoltaic Array or the output current value of current detecting unit, and accordingly the in good time angle of solar tracking system is carried out trickle adjustment, It is embodied in: the photovoltaic array of current flow detection module detection or the output current value of current detecting unit are Ia, can revolve Turning bracket driver drives rotatable support frame to continue to rotate forward, and photovoltaic array or electric current that current detection module detects again are examined The output current value surveying unit is Ib;If Ib > Ia, rotatable support frame rotates forward continuing, until output current value no longer increases Add;If output current value Ib < Ia, rotatable support frame reversely rotates, until output current value is not further added by.
The invention has the beneficial effects as follows,
1, detect that output current value is reduced to I when current detection module2Time, runing rest driver will be stopped the rotation and be propped up The tracking of frame runs and is back to return/wind resistance guard mode night, utilizes the colour of sky to be darkened between strong wind arrival during this period of time, makes too Sun can be followed the tracks of system and be back to wind resistance state in advance, and air velocity transducer is played supplementary function, and tracking system can be greatly improved can By property.
2, in the case of the irradiance such as cloudy day are low, solar tracking system is not followed the tracks of, and saves electric energy.
3, solar tracking system low cost of the present invention, it is adaptable to the Distributed Application of negligible amounts, and improve too Sun can follow the tracks of the reliability of system.
4, normally following the tracks of in running at solar tracking system, main control singlechip periodically compares photovoltaic module Output current value, is finely adjusted whole to the angle of solar tracking system, it is ensured that the photovoltaic being arranged on solar tracking system The output of assembly maximizes.
