Problems solved by technology

At present, the control system of tracking brackets for inclined single-axis photovoltaic power generation usually uses PLC and single-chip microcomputers as the control core, and uses inclination sensors to collect the inclination angle of each tracking bracket. Several functional components of each tracking bracket control system overlap and the operation is cumbersome.

Abstract

The invention discloses a photovoltaic support group tracking control device and method based on machine vision, and the device comprises inclined single-shaft photovoltaic support groups, each inclined single-shaft photovoltaic support group is composed of a plurality of inclined single-shaft photovoltaic supports which are arranged in a matrix, and each inclined single-shaft photovoltaic support comprises a solar panel, a support, a tracking shaft, a drive motor, and a support tracking controller. The driving motor is connected with the support tracking controller and the tracking shaft, a CCD camera is arranged above the inclined single-shaft photovoltaic support groups and located on one side face of the inclined single-shaft photovoltaic support groups, and a plurality of measuring points are arranged on the side edge, away from the CCD camera, of each solar panel. A plurality of reference points are arranged in the center of four adjacent inclined single-axis photovoltaic supports arranged in a matrix mode, the support tracking controllers are connected with an industrial personal computer system, and the industrial personal computer system is connected with the CCD camera. According to the invention, the cost of the official support tracking control system is reduced, on-site construction is facilitated, and the installation difficulty is reduced.

Description

Technical field [0001] The present invention is in the field of solar photovoltaic technology, relates to a photovoltaic stent based on machine vision tracking control means further relates to a photovoltaic stent tracking control method based on machine vision. Background technique [0002] Solar energy is an abundant resource, pollution-free energy alternatives, development and utilization of solar energy in recent years has been paramount, in order to improve the collection efficiency of solar energy, the emergence of auxiliary equipment a solar collection device, that allows the stent by tracking PV modules placement angle varies position of the sun varies, the amount of solar energy collection increased significantly improve the power generation efficiency of the photovoltaic module. Currently, the control system monoaxial oblique tracking photovoltaic stent generally PLC, microcontroller core, using the tilt sensor acquisition of inclination of each track support, a plurali...
