Abstract
The invention discloses a fully-automatic solar dual-axis tracking device and a control system. The control system adopts a method of combining sun tracking and photoelectric tracking, dual-axis motion is used for achieving control on a height angle and an azimuth angle, and two-dimensional degree of freedom motion is realized. The basic principle of the solar tracking control system is that: firstly, a sun motion trajectory method is adopted for calculating the height angle and the azimuth angle of the sun, and rotation of a stepper motor is controlled via a single chip microcomputer; and secondly, signals values of five photosensitive resistors arranged at five azimuths of the east, the west, the south, the north and the middle are received, photoelectric control is adopted for increasing the rotation precision of the stepper motor, and all-direction high-precision solar tracking can be realized. As is proved by practice, the tracking control system can improve the photoelectric conversion efficiency of a solar panel.
Description
Technical field
Patent of the present invention relates to a kind of full automatic solar double-axis tracking device for solar panel and control system, belongs to solar electrical energy generation and research on utilization field.
Background technology
The energy is the material base that human society is depended on for existence and development.Current, the overwhelming majority of countries comprising China all with fossil energies such as oil, rock gas and coals for main energy sources.Along with the continuous deterioration of day by day exhaustion and the global environment of fossil energy, a lot of country all conscientiously exploring the diversified approach of the energy, actively develops the research and development of new and renewable sources of energy.Although in foreseeable future, the mineral fuel such as coal, oil, rock gas will occupy suitable proportion in world's energy structure, but people utilize pay attention to day by day to the sustainable energy resources such as nuclear energy and sun power, wind energy, geothermal energy, hydraulic energy, biological energy source, ratio shared in whole energy resource consumption improves significantly.Estimate that sustainable energy can contend with fossil energy in following 5 to 10 years, thus terminate the situation of fossil energy dominance.
The hope place of the sun power seemingly future society energy.Compared to fossil energy, the advantage of sun power is: the first, and it is the mankind's the abundantest utilizable energy.According to estimates, in very long in the past 1,100,000,000 years, the sun consumes 2% of itself energy, can be described as inexhaustible.The second, on the earth, anywhere there is sun power, can develop on the spot, there is not transportation problem, especially the underdeveloped rural area of traffic, island and backcountry are had more to the value of utilization.3rd, sun power is a kind of energy of cleaning, when development and utilization, can not produce waste residue, waste water, waste gas, also not have noise, more can not affect the ecologic equilibrium.Solar illuminating system achieves the utilization to regenerative resource, and first its advantage is save electrical network electric energy, saves disposable resource day by day in short supply, and decreasing pollution discharge simultaneously, this is a kind of social benefit.But promote the application of sun power and also there is strong economic function, in other words temptation economically, that is both economize on electricity, save money again, really reduce " combined lighting cost ".
Full automatic solar double-axis tracking device and control system are from solar source orientation method and control technology, and adopt new tracking and photovoltaic power generation apparatus technology, generating capacity improves at least 30% compared with fixed angle solar LED illuminating system.The sun automatic tracking system that the present invention studies is SCM Based automatic control system, combines the advantage that Photoelectric Detection is followed the trail of and looked daily motion trajectory track two kinds of modes, two kinds of trace modes is combined cleverly, make system more stable.
Summary of the invention
The object of the invention is with sun power following principle, a kind of the full automatic solar double-axis tracking device and the control system that can be used for solar panel are provided.
Structure of the present invention comprise solar panel, to day tracker, photoresistance, vertical rod, gear wheel, base, column, transverse axis, pinion wheel, reducing motor, tracking control unit, stepper motor, support.
Vertical rod is nested on base, tracking control unit is fixed on vertical rod, transverse axis is fixed on tracking control unit, stepper motor is fixed on base, stepper motor is fixed on tracking control unit, vertical rod is engaged with stepper motor by gear wheel, and transverse axis is engaged with reducing motor by pinion wheel, more than constitutes the module mounting bracket of full automatic solar double-axis tracking device and control system; Solar panel is arranged on column, be connected with support by column, support is fixing on the horizontal axis, photoresistance is arranged on on sun-tracker by the direction of all directions, the left side of solar panel is then fixed on to sun-tracker, tracking control unit is made up of Single Chip Microcomputer (SCM) system, is connected as the control core of whole device by circuit with the controlled device in device;
During use, under the driving of tracking control unit, rotate up and down by controlling reducing motor and stepper motor drive vertical rod left rotation and right rotation and transverse axis, thus drive solar panel rotation up and down, while solar panel rotates, to day controller work, according to photoresistance feedack, the angle of rotating accurately is controlled; In order to prevent solar panel after rotation process terminates from producing error because of gravity, work to reducing motor and step motor control self-locking immediately when rotating the moment tracking control unit stopped; Solar panel can be powered can run work for a long time for the monolithic system in tracking control unit; After using, when photoresistance detects at dark, tracking control unit enters power-off program, and solar panel recovers initial position, and full automatic solar double-axis tracking device and control system enter low consumption pattern economize energy.
The invention has the beneficial effects as follows: owing to applying sun power Trajectory Arithmetic in uranology, can accurately in the position of the overcast and rainy judgement sun; Owing to having installed photoresistance, can detect accurately and judge round the clock, can interrupt service routine automatically when night being detected; Mounting support structure is simple, and without specific demand, thus this device is by the restriction in geographic position, easy to use, flexibly while, can also tracking accuracy be ensured.Current solar panel adopts fixed angle to install mostly, cannot ensure the vertical irradiation of sunshine, can not make full use of solar energy resources, and the present invention well solves this problem.The data having experiment to record also illustrate, under the same conditions, use the solar panel generating efficiency of automatic tracking system to improve 30%.
