Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the total system schematic diagram of this distributed photovoltaic power generation sun direct projection automatic servo system.
Embodiment
Please refer to Fig. 1, distributed photovoltaic power generation sun direct projection automatic servo system, for controlling the light receiver position of generating battery plate 100, it comprises servo control circuit 10, light sensing module 20, cell panel installing rack 30, servo recurrence circuit 40 and gear train 50.
This servo control circuit 10 comprises the driving power, differential relay 11 and the rotating forward drive motors 12 that are connected in series mutually, particularly the normally opened contact of this differential relay 11 is connected in series this driving power and rotates forward drive motors 12, in the present embodiment, this driving power is 220V AC power.
This servo returns circuit 40 and comprises the driving power, the time relay 41, reverse rotation driving motor 42 and the travel switch 43 that are connected in series mutually, and the output shaft of this reverse rotation driving motor and this gear train are in transmission connection.
This light sensing module 20 comprises two two sensing cell panel 21 and sunshading boards 22 in the same plane, this sunshading board 22 be placed in this two sensing cell panel 21 between and perpendicular to this two sensing cell panel 21, the each corresponding sensing cell panel 21 in the two sides of this sunshading board 22 and the both sides of this sunshading board 22 are respectively towards east side and the west side in geographical position, and this two sensings cell panel 21 has identical specification; The output of this two sensings cell panel 21 is all connected to this differential relay 11 to drive this differential relay 11 action, and particularly the output of this two sensings cell panel 21 is all connected to the control end of this differential relay 11 to drive the normally opened contact of this differential relay 11 closed.
