Abstract
The present invention relates to a kind of high-precision sun tracing systems, including the following steps successively carried out: calculate position of sun: starting view daily motion track following mode calculates solar elevation and solar azimuth by astronomical algorithm according to the time of offer and latitude and longitude information；Aligning: operation is carried out by position of sun information of the controller to input, issues pulse, direction signal, and drive the theoretical position of the solar panel rapid alignment sun by stepper motor；Photoelectricity follows: error signal is fed back to controller by photoelectric sensor, and controller handles feedback signal, then exports pulse, adjust the angle of stepper motor, keep solar energy light collecting plate vertical with incident ray.
Description
Technical field
The present invention relates to technical field of electromechanical control, and in particular to a kind of high-precision sun tracing system.
Background technique
During photovoltaic power generation, solar panels will affect the efficiency of photovoltaic power generation with direct sunlight angle, it is therefore desirable to
Solar tracking system, existing solar tracking system have photoelectric tracking, view daily motion track following and photoelectric tracking and view day with
The tracking that track mutually switches, but existing solar tracking system influences vulnerable to weather condition and is easy to produce accumulated error.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of high-precision sun tracing systems.
To achieve the above object, the invention adopts the following technical scheme:
A kind of high-precision sun tracing system, including the following steps successively carried out:
Calculate position of sun: starting view daily motion track following mode is calculated according to the time of offer and latitude and longitude information by astronomy
Method calculates solar elevation and solar azimuth；
Aligning: operation is carried out by position of sun information of the controller to input, issues pulse, direction signal, and pass through
The theoretical position of the stepper motor drive solar panel rapid alignment sun；
Photoelectricity follows: error signal is fed back to controller by photoelectric sensor, and controller handles feedback signal, then exports arteries and veins
Punching, adjusts the angle of stepper motor, keeps solar energy light collecting plate vertical with incident ray.
The invention has the following beneficial effects:
1, the solar tracking system that the present invention designs is swift in motion, and the most fast time can capture position of sun.
2, the solar energy that the present invention designs can effectively eliminate accumulated error with middle system.
Specific embodiment
