Photovoltaic power generation single-axis tracking control system

Abstract

The invention discloses a photovoltaic power generation single-axis tracking control system. The photovoltaic power generation single-axis tracking control system comprises a controller, a signal detection unit for converting an acquired optical signal into an electric signal and transmitting the electric signal to the controller, a motor controlled by the controller and used for driving a photovoltaic module to rotate synchronously so as to track sunlight, and a first position detection unit and a second position detection unit both respectively for detecting an initial rotation position and an ended rotation position of the photovoltaic module, wherein the first position detection unit and the second position detection unit compose a detection device used for limiting a rotation angle range for tracking the sunlight of the photovoltaic module; the controller controls the motor based on the signals detected by the first position detection unit and the second position detection unit; and the motor is in transmission connection with the photovoltaic module. The photovoltaic power generation single-axis tracking control system has a simple structure, a rational design, convenient and simple operation, low cost, good use effects, and capabilities of solving the problems of a complex structure, fussy control process, high investment cost and great difficulty in the assembling and maintaining process of the conventional photovoltaic power generation single-axis tracking control system.
