<p>Disclosed is a sunlight automatic tracking system for a three-dimensional photovoltaic cell, comprising: a CPU control circuit, a servo drive circuit and a photometric system which are electrically connected successively, wherein the photometric system is installed on a solar light board; the photometric system outputs an X-axis pulse signal, a Y-axis pulse signal and a Z-axis pulse signal to the CPU control circuit; the CPU control circuit controls the operation of a first motor in the servo drive circuit via a first pulse signal, a first operating state control signal and a first direction control signal; the CPU control circuit controls the operation of a second motor in the servo drive circuit via a second pulse signal, a second operating state control signal and a second direction control signal; the first motor and the second motor drive the solar light panel to rotate; and the CPU control circuit initializes the first pulse signal, the first direction control signal, the second pulse signal and the second direction control signal via the Z-axis pulse signal. The system reduces usage costs and improves the working efficiency.</p> |
