Description of the drawings
A stage of:
in the morning, when the machine starts to operate, the computer 5-2 is controlled to operate, and an electric signal is sent to the photovoltaic panel circumferential unfolding mechanism 8 to start to operate, and each photovoltaic panel is independently controlled by the small motor 8-2 which moves around the central axis and is controlled by the computer: the independent small motors start to move around the central axis 8-1 of the photovoltaic panel anticlockwise to drive the thin film solar photovoltaic panel 1 to rotate, when the position sensor 8-3 under each photovoltaic panel detects that the corresponding photovoltaic panel moves to the designated position of the computer, an electric signal is sent to the control computer 5-2, so that the independent small motors 8-2 start to be finely adjusted so as to stop working, each thin film solar photovoltaic panel 1 moves to the corresponding position and stays, and the thin film solar photovoltaic panel 1 is unfolded anticlockwise along the central axis 8-1 of the photovoltaic panel. The GPS signal receiving device 3 starts to collect GPS signals sent by satellites in real time and simultaneously sends the GPS signals to the control computer, the control computer 5-2 calculates the sun position according to the received GPS signals by utilizing time control, simultaneously calculates the pointing position with highest photoelectric conversion efficiency of the thin film solar photovoltaic panel, the control computer 5-2 sends signals to the rotatable supporting structure 6 and the driving motor, namely the rotatable base 7, the driving motor D-14-1 and the driving motor D-24-2 in the rotatable supporting structure 6 start to work to turn the thin film solar photovoltaic panel 1 to the corresponding positions, then the light sensing module 2 sends signals to the control computer according to current solar rays, fine adjustment is carried out on the position of the thin film solar photovoltaic panel at the same time, and finally electric energy is stored in the lead-acid storage battery.
Two stages:
when the sun falls into the mountain in the afternoon, according to the position signal of the position sensor 8-3, the control computer 5-2 sends an electric signal to the small motor 8-2 which is independently controlled by each photovoltaic panel and moves around the central axis: the individual small motors and the driving motors D-14-1 and the driving motors D-24-2, and the real-time position information sent by the position sensor 8-3 when all the individual small motors 8-2 and the driving motors D-14-1 and the driving motors D-24-2 operate enables each thin film solar photovoltaic panel 1 to be recovered clockwise and then move to an initial position, and then the computer 5-2 is controlled to enter a standby state for timing.
