Abstract

A solar energy tracker belongs to equipment automatically tracking sun light; the tracker can automatically adjust an angle of a solar panel in a system according to the angle of the sun at different time every day in a year; so the sun light can irradiate on the solar panel in a maximum incidence angle (approaching 90 degrees), and solar energy can be converted in a maximum power by the solar panel. The solar energy tracker comprises a one-chip microcomputer module; and the tracker is characterized by also comprising an AD acquisition module connected with the one-chip microcomputer module, a motor drive module connected with the one-chip microcomputer, a light feedback control connected with the one-chip microcomputer module, a data display module connected with the one-chip microcomputer module, and a power module connected with the one-chip microcomputer module. The solar energy tracker is not affected by region factor, is high in practical value, simple in operation, easy to realize, and has certain promotion value.

Description

Solar tracking device

Technical field

The utility model relates to a kind of solar tracking device, relate to a kind of tracker of following the tracks of the angle at sun place every day in 1 year specifically, 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, direction of illumination and intensity continuous problem such as variation in time, and the utility model carries out design system in order to improve solar energy utilization rate.

Summary of the invention

Technical problem to be solved in the utility model 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 scheme that the utility model adopted is: a kind of solar tracking device comprises one-chip computer module; It is characterized in that: also comprise the AD acquisition module that links to each other with one-chip computer module, the motor drive module that links to each other with single-chip microcomputer, the light feedback module that links to each other with one-chip computer module, the data disaply moudle that links to each other with one-chip computer module, the power module that links to each other with one-chip computer module.Described one-chip computer module is the main control module of whole solar tracking device, and main effect is processing and the control of carrying out data.

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

Described motor drive module is used for realizing the angular deflection control to solar panel, so that follow the tracks of the sun.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and example.

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

As shown in Figure 2, described one-chip computer module 1 adopts 8 single-chip microcomputer series A Tmega16, and 32 universaling I/O ports 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 AD acquisition module 2 links to each other with the AD1 passage of single-chip microcomputer, the solar panel output voltage is carried out AD gather, carry out carrying out control corresponding again after the calculation process through the value of AD that different time sections is gathered by one-chip computer module 1.

Shown in Fig. 4,5, described motor drive module 3 is divided into the motor-driven on level and the vertical both direction, signal according to one-chip computer module 1 output drives the horizontal direction motor to the rotation of sun yawing moment, makes the realization of cell panel deflection angle vertical with sunray thereby drive the vertical direction motor then.

Shown in Fig. 6,7, described light feedback module 4 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 the extraneous light Acquisition Circuit is sent useful signal (when there are certain angle in solar panel and sunray, photoresistance on diverse location utilizes its sensitivity to light, feed back different magnitude of voltage differences, 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 handled by the signal that the outside is sent here, draw controlling schemes in the horizontal direction with on the vertical direction, distinguish the direct current motor drive circuit on controlling level and the vertical direction then, 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.
