Abstract
The invention relates to a novel polar axis type sun tracking system control circuit which is mainly composed of a tracking module, a single chip microcomputer controller and a driving module. The tracking module is formed by combining photoelectric tracking and sun viewing tracking. Program tracking is adopted according to a sun viewing motion trail in the first stage, and a photoelectric sensor is adopted to correct the tracking in the second stage. The driving module drives a stepping motor and a linear motor to run to respectively control rotating around the polar axis and pitching angle adjustment to achieve automatic sun tracking. The wind speed and direction, and the illumination intensity and the solar battery parameters are detected in real time during tracking. A polar axis type automatic sun tracking system is adopted, the photoelectric tracking and the sun viewing tracking are adopted, the system is stable, and the accuracy is higher.

Summary of the invention
The problem existing for prior art, the object of this invention is to provide a kind of control circuit of polar shaft type solar tracking system, can make the acceptance rate of photovoltaic cell improve greatly, thereby can utilize solar energy resources effectively, more fully, widen the application of sun power.
The technical solution used in the present invention is: a kind of control circuit of polar shaft type solar tracking system is mainly by tracking module, singlechip controller and driver module composition; Tracking module combines by photoelectric tracking with depending on a day tracking, and the first order is by following the tracks of by program depending on daily motion track, and the second level adopts photoelectric sensor to correct tracking; The running of driver module Driving Stepping Motor and linear electric motors, controls respectively around pole axis and rotates and angle of pitch adjusting, with realize to the sun from motion tracking; Follow the tracks of and detect in real time wind speed and direction, intensity of illumination and solar cell parameter simultaneously.
Following the tracks of depending on day of described tracking module is by calculating running track from sun depending on daily motion TRAJECTORY CONTROL software, and then real-time follow-up; Photoelectric tracking is to utilize photoelectric sensor to measure the deviation between incident sunray and systematic optical axis.While starting tracking module, adopt timing to judge whether light intensity voltage reaches photoelectric tracking scope, if reaching photoelectric tracking scope startup photoelectric tracking revises, look daily motion track following if do not reach the employing of photoelectric tracking scope, in the time reaching the light intensity of photoelectric tracking, start photoelectric tracking correction.
Described wind speed and direction detects and intensity of illumination detects in the time destructive strong wind being detected; system should make solar panel forward position, best oblique angle to; motor stalling afterwards; protection solar cell; intensity of illumination sensor detects the intensity of illumination of there and then; and then judgement weather conditions, so that the switching of tracing mode.
Temperature, the voltage and current of described solar cell parameter Real-time Collection solar cell, so that solar cell Maximum Power Output.
The present invention compared with prior art has the following advantages:
1. the present invention is reasonable in design, simple in structure and circuit part line is simple;
2. adopt polar mounts automatic tracking system can make the receptance of photovoltaic cell improve greatly, thus can be more effective, utilize solar energy resources more fully, widen the application of sun power.On the other hand, effectively utilize sun power can alleviate the energy crisis of growing tension and the ecologic environment of severe contamination, this sustainable development to the mankind has great significance.
3. although position angle-height angie type double-axis tracking can be realized tracking accuracy, but physical construction is more complicated, system cost is high, and position angle and elevation angle motor action are frequent, and energy consumption is higher, elevation angle and position angle calculating are more complicated etc., adopt polar mounts comprehensive trace mechanism, simple in structure, tracking accuracy is high, cost is relatively low, consumes energy low.
