Abstract

Disclosed is a solar tracker. By the aid of the tracker, the angle of a solar panel of a system can be automatically adjusted in accordance with sun angles of different moments of every day of every year, the sun light can shines to the solar panel at a maximum angle of incidence (approaching 90 angles), and the solar conversion of the solar panel can be achieved in the maximum power. The tracker comprises a single ship microcomputer module (1), an analog-digital (AD) collecting module (2), a motor drive module (3), a light ray feedback module (4), a data display module (5) and a power supply module (6). The tracker is not limited by regional factors, the practical value is high, the operation is simple, the implementation is easy, and the popularization value is good.

Description

Solar tracking device

Technical field

The present invention relates to a kind of solar tracking device, relate to specifically a kind of tracker of following the tracks of the angle at sun place every day in 1 year, utilize single-chip microcomputer, in conjunction with corresponding circuit, come the angle at real-time follow-up sun place, thereby sunray is radiated on the solar panel with maximum incident angle (near 90 °), realizes that cell panel is with the peak power conversion solar.

Background technology

Sun power is the renewable green energy resource of the very abundant and cleanliness without any pollution of a kind of reserves, as long as make sun power become the energy that can be widely used, it will greatly alleviate human energy crisis, improve the human settlement, promote the major progress of human society.As a kind of green energy resource of cleanliness without any pollution, development prospect is boundless, has become the green energy resource that various countries competitively develop.But sun power exists, and density is low, intermittent, the continuous problem such as variation of direction of illumination and intensity time, and the present invention carries out design system for the utilization factor that improves sun power.

Summary of the invention

Technical matters to be solved by this invention is, a kind of solar tracking device is provided, can follows the tracks of the angle at sun place, adjust solar panel, sunray is radiated on the solar panel with maximum incident angle (near 90 °), realizes that cell panel is with the peak power conversion solar.

The technical solution adopted in the present invention is: a kind of solar tracking device comprises (1) one-chip computer module (2) AD acquisition module (3) motor drive module (4) light feedback module (5) data disaply moudle (6) power module.

Described (1) one-chip computer module is the main control module of whole solar tracking device, and Main Function is processing and the control of carrying out data.

Described (2) AD acquisition module mainly is the solar panel output voltage to be carried out AD gather, and then is transferred to one-chip computer module and carries out the data processing.

Described (3) motor drive module is used for realizing the angular deflection control to solar panel, in order to follow the tracks of the sun.

Described (4) light feedback module is mainly used in the collection of solar panel ambient light signal, carries out judgement and the control of angle of sun rays thereby be used for one-chip computer module.

Described (5) data disaply moudle adopts 12864 Liquid Crystal Modules, is used for showing in real time the output voltage of solar panel.

Embodiment

The invention will be further described below in conjunction with accompanying drawing and example.

As shown in Figure 1, solar tracking device of the present invention comprises (1) one-chip computer module (2) AD acquisition module (3) motor drive module (4) light feedback module (5) data disaply moudle (6) power module.

As shown in Figure 2, described (1) one-chip computer module adopts 8 single-chip microcomputer series A Tmega16, and 32 general purpose I/O mouths have 8 road AD ALT-CH alternate channels, is the master control core of whole solar tracking device system.

As shown in Figure 3, described (2) AD acquisition module links to each other with the AD1 passage of single-chip microcomputer, the solar panel output voltage is carried out AD gather, carried out carrying out again corresponding control after the calculation process through the value of AD that different time sections is gathered by (1) one-chip computer module.

As shown in Figure 4, described (3) motor drive module is divided into the motor-driven on level and the vertical both direction, signal driver horizontal direction motor according to the output of (1) one-chip computer module rotates to sun yawing moment, makes the realization of cell panel deflection angle vertical with sunray thereby then drive the vertical direction motor.

As shown in Figure 5, described (4) light feedback module is used for the collection of solar panel ambient light signal, by relatively coming to determine large-scale deviation in the photoresistance in peripheral four orientation and center photoresistance, just can judge the direction of sunshine deflection and the size of deviation, thereby realize following the tracks of sunshine according to the variation of output voltage.

Single-chip microcomputer is when executive routine, when having the extraneous light Acquisition Circuit to send useful signal (when there are certain angle in solar panel and sunray, photoresistance on diverse location utilizes it to the sensitivity of light, feed back different magnitudes of voltage different, than device single-chip microcomputer is exported a level signal by voltage-contrast again, single-chip microcomputer judges have deviation to exist according to the situation of level), single-chip microcomputer is processed by the signal that the outside is sent here, draw control program in the horizontal direction with on the vertical direction, then control respectively the direct current motor drive circuit on the horizontal and vertical direction, thereby drive the direct current generator work on the both direction.The light Acquisition Circuit is fed back the deflection situation of sunray constantly in the direct current generator course of work, has also just reached the purpose of real-time follow-up sunray.
