Abstract

The invention discloses an MATLAB image recognition-based dual-axis light-seeking system, which comprises a horizontal disc rotation unit, a photovoltaic cell panel rotation unit, an image collection module and an image processing module for transporting and processing an image, a system control module and a measurement feedback module for feedback, wherein an output shaft of a first stepper motor is fixedly connected with the center of the bottom of a horizontal turnplate through a flange coupling; a drive module of the first stepper motor is connected with a power supply of a 12V lithium battery; a second stepper motor is fixed at one side of the horizontal turnplate of the horizontal disc rotation unit and a counterweight is fixed at the other side of the horizontal turnplate; the output shaft of the second stepper motor is connected with the middle of the side surface of a photovoltaic cell panel; the drive module of the second stepper motor is connected with the 12V lithium battery; and the system control module controls reversing directions and rotating speeds of the motors. According to the dual-axis light-seeking system, the photovoltaic cell panel can be adjusted always towards the position facing the sun in real time to reach the optimum position of receiving the sunlight, and the utilization rate of light energy is improved.

Description

technical field [0001] The invention relates to the technical fields of new energy and image processing and recognition, in particular to a dual-axis light-seeking system based on MATLAB image processing. Background technique [0002] With the development of new energy technology, how to efficiently develop and utilize solar energy has become one of the focuses of people's exploration in the field of new energy. Photovoltaic power generation is mainly a technology that uses sunlight to irradiate semiconductor interfaces such as silicon to convert light energy based on the photovoltaic effect. Solar power generation is sustainable, not subject to geographical restrictions, and can be directly developed and utilized. Under this background, many places have successively established and developed solar power stations, mainly relying on large-scale photovoltaic arrays arranged in a fixed azimuth to collect light energy. However, due to the dispersion of light and the position of ...
