Abstract
The invention discloses an intelligent double-precision sun automatic tracking system in the field of a solar energy tracking system. The intelligent double-precision sun automatic tracking system comprises a photoelectric sensor installed on a solar cell panel; the signal output end of the photoelectric sensor is connected with the signal input end of a single-chip microcomputer through an A/D converter circuit; the solar cell panel is also provided with a limit circuit; the signal output end of the limit circuit is connected with the signal input end of the single-chip microcomputer; the signal input end of the single-chip microcomputer is connected with a clock circuit; the signal output end of the single-chip microcomputer is connected with a drive circuit; and the drive circuit controls the solar cell panel to finish horizontal and vertical rotation actions respectively through a horizontal stepping motor and a pitching stepping motor. According to the invention, the system mainly utilizes locus tracking based on a sun motion rule and a photoelectric detection module is used for carrying out a tracking correction double-precision tracking mode so as to realize the round-the-clock fine tracking of the sun and enable the system tracking precision to be higher; and besides, the system also has the advantages of low energy consumption, accurate data, high applicability and enhanced sun tracking accuracy rate, thereby being suitable for use in a solar energy acquisition process.
Description
Technical field
The present invention relates to a kind of solar tracking system, particularly a kind of double precision solar automatic tracking system.
Background technology
The range of application of sun power is increasingly extensive in recent years, and such as solar water heater, solar electrical energy generation, desalinization, solar hydrogen making etc. all wishes efficiently to receive and utilize sun power.The characteristics that yet sun power density is low, intermittent, space distribution constantly changes, proposed requirements at the higher level to the accurate tracking of the sun.The method of following the tracks of at present the sun can be summarized as two kinds: photoelectric tracking and look the daily motion track following.Photoelectric tracking is highly sensitive, and structural design more for convenience, but is subject to the impact of light intensity and weather very large; And the advantage of looking the daily motion track following is can round-the-clock real-time follow-up, but the method program complexity, oneself power consumption is large, and lacks the defencive function under severe weather conditions.
Summary of the invention
The purpose of this invention is to provide a kind of intelligent double precision solar automatic tracking system, make systematic tracking accuracy high, energy consumption is low, and data are accurate, and applicability is strong.
The object of the present invention is achieved like this: a kind of intelligent double precision solar automatic tracking system, comprise the photoelectric sensor be arranged on solar panel, the signal output part of described photoelectric sensor is connected with the signal input part of single-chip microcomputer through the A/D change-over circuit, limit circuit also is installed on described solar panel, the signal output part of described limit circuit is connected with the signal input part of single-chip microcomputer, the signal input part of described single-chip microcomputer also is connected with circuit all the time, the signal output part of described single-chip microcomputer is connected with driving circuit, described driving circuit completes the upper and lower spinning movement of level by horizontal stepper motor and pitching step motor control solar panel respectively.
As a further improvement on the present invention, described single-chip microcomputer is the AT89S52 single-chip microcomputer.
When the present invention works, control structure mainly is divided into two parts: look daily motion track following part and photoelectric tracking part, gather clock information depending on daily motion track following part by single-chip microcomputer and calculate current position of sun, the stepper motor of level of control and pitching both direction rotates, and realizes from motion tracking; The photoelectric tracking part gathers intensity signal by photoelectric sensor, after the A/D conversion, signal feedback is arrived to controller, then the action deviation of looking the daily motion track following by the stepper motor correction, adjusts solar panel and keeps vertical with sunshine all the time.Compared with prior art, beneficial effect of the present invention is: it is main that the present invention adopts the track following of looking the daily motion rule, the Photoelectric Detection module is carried out the double precision tracking mode of tracking correction, by follower being carried out to the control of level, two degree of freedom of pitching, realizes the round-the-clock meticulous tracking to the sun, make systematic tracking accuracy high, energy consumption is low, and data are accurate, and applicability is strong, improve the solar tracking accurate rate, reached the purpose that takes full advantage of sun power.The present invention can be used in the solar energy acquisition process.
The accompanying drawing explanation
Fig. 1 is control principle block diagram of the present invention.
