Abstract

The invention relates to a novel double-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 composed of a photoelectric detection module and a sun angle tracking module. A global position system (GPS) module provides required data for the sun angle tracking module. The photoelectric detection is conducted through a photoelectric sensor. The driving module drives a stepping motor 1 and a stepping motor 2 to run to control a rotating disc to rotate in the horizontal direction and the vertical direction 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 double-axis type automatic sun tracking system is adopted, the photoelectric tracking and the sun angle tracking are adopted, the system is stable, and the accuracy is higher.

Description

A kind of control circuit of novel biaxial formula solar tracking system

Technical field

The present invention relates to a kind of device of solar generating field, particularly relate to a kind of control circuit of novel biaxial formula solar tracking system.

Background technology

The total amount of solar energy resources is very large, is the disposable energy, is again regenerative resource, be free use, without transportation three-dimensional clean energy resource.But sun power has dispersiveness, although the total amount of the solar radiation of arrival earth surface is very huge, its energy flux density is low.Every square metre, the ground sun power only having about 1000W.Simultaneously, sun power also has instability, because earth surface is subject to round the clock, the weather effect of natural conditions of season, geographic latitude, random variation, making to arrive certain any sun power is intermittently, direction of illumination and intensity time constantly change, these drawbacks limit of sun power large-scale exploitation solar energy resources.Therefore, on the existing defect basis of the sun, in order fully to develop solar energy resources, twin axle solar automatic 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.

Summary of the invention

The problem existing for prior art, the object of this invention is to provide a kind of control circuit of novel biaxial formula solar tracking system, can make the acceptance rate of photovoltaic cell effectively improve, 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 novel biaxial formula solar tracking system is mainly by tracking module, singlechip controller and driver module composition; Tracking module is made up of Photoelectric Detection and sun angle tracking module, and sun angle tracking module provides required data by wireless telecommunications GPS module, and Photoelectric Detection is detected by photoelectric sensor; Driver module Driving Stepping Motor 1 and stepper motor 2 turn round, the respectively dial rotation of level of control direction and vertical direction, 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.

Further, described wireless telecommunications GPS module can provide required local time, date, longitude and latitude, height above sea level and pressure data information, calculate elevation angle and the position angle of the current sun and input in single-chip microcomputer, judging that also judge by reading gps data day and night.

Further; 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.

Further, temperature, the voltage and current of described solar cell parameter integration module 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 twin axle 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.

Embodiment

In Fig. 1, a kind of control circuit of novel biaxial formula solar tracking system, is mainly by tracking module, singlechip controller and driver module composition; Tracking module is made up of Photoelectric Detection and sun angle tracking module, and sun angle tracking module provides required data by wireless telecommunications GPS module, and Photoelectric Detection is detected by photoelectric sensor; Driver module Driving Stepping Motor 1 and stepper motor 2 turn round, the respectively dial rotation of level of control direction and vertical direction, 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.

The course of work of the present invention is: single-chip microcomputer is by reading the data message of wireless telecommunications GPS module, judge daytime and night, intensity of illumination sensor detects cloudy day and fine day, when fine day, enable Photoelectric Detection tracing mode, when the cloudy day, system is in suspending waiting status; While becoming fine day by the cloudy day, enable sun angle control model, the Time of Day and the latitude and longitude information that now provide by reading wireless telecommunications GPS module, calculate elevation angle and the position angle of the sun, determine the position of the sun, Driving Stepping Motor 1 and stepper motor 2 turn round, and make mechanical hook-up aim at gradually the sun, system enters detection waiting status subsequently, stepper motor quits work, and when the sun departs from after certain angle, Photoelectric Detection again starts search and follows the tracks of the sun; Circulation always, until darkness; Numeral wind speed wind direction sensor detects wind velocity signal at that time, and battery parameter acquisition module will gather the parameter of solar cell.
