Flip-type solar trolley automatic light-tracking system and control method

Abstract

The invention discloses a flip-type solar trolley automatic light-tracking system and a control method, and belongs to the technical field of solar power supply. The system consists of five parts: a main body frame unit, a quasi-double-shaft device, a multipath detection sensor, a flip structure and a light-tracking system control mechanism. According to the invention, one end of an aluminium framework is fixed at the tail end of a solar trolley through a fixing rotating shaft, and two sides of the aluminium framework are stably connected with a vehicle body through two telescoping rod motors. A central solar panel is fixed on the aluminium framework, and two solar panels at two sides are reinforced through angle aluminum. The solar panels are reinforced through fixing three sides of the frame. The multi-sensor fusion technology is used for the compensation and calculation tracking of an outer ring through combining with a sun-viewing rail tracking method, and the outer ring is quickly tuned nearby the azimuth angle of the sun in a coarse manner. Afterwards, four-quadrant photoelectric sensors are used for collecting the azimuth angle information of the sun, and the PID algorithm is employed for controlling duty ratio precise control motors with different PWM outputs, thereby achieving the accurate tracking of the azimuth of the sun.

Description

technical field [0001] The invention discloses an automatic light-following system and a control method for a flap-type solar car, belonging to the technical field of solar power supply. Background technique [0002] The western region of my country is rich in solar energy resources, and the annual radiation is 6700MJ / m 2 Above, the amount of radiation per square meter is equivalent to the heat emitted by the combustion of 230kg standard coal. However, due to the vast land and sparse population in the western region, the distance between each city is relatively long, resulting in long transmission lines. At present, robots aiming at power transmission lines emerge in an endless stream, and most of their energy supply is to supply power to batteries by fixing solar panels on the body. Since the incident angle of light cannot be kept perpendicular to the solar panel in most cases, fixed solar panels cannot utilize solar energy resources with maximum efficiency, and at certai...

Problems solved by technology

[0015] The existing inventions and technologies cannot solve the problem of solar panel shaking caused by the automatic tracking of solar cars: the existing related inventions and technologies only use a single axis to fix the middle, and the surroundings of the solar panel are suspended, and the sun is tracked through the change of the axis and the axis
