Abstract
A sun tracking and control system comprises a main controller, a sunlight tracking sensor, a one-dimensional direct-current servo system, and a solar panel and limit switches, wherein the main controller receives signals of the sunlight tracking sensor and controls the one-dimensional direct-current servo system to drive the solar panel to rotate after analysis and processing so that the solar panel is vertical to sunlight and the maximum absorption rate of solar energy is achieved. The one-dimensional direct-current servo system simultaneously drives the sunlight tracking sensor to rotate so that the direction of the sunlight tracking sensor is the accurate position of the sunlight at the time. The one-dimensional direct-current servo system is provided with two limit switches in the east and in the west. When the solar panel is to reach the positions of the limit switches in a rotating mode, the limit switches send signals to the main controller to stop operation of the servo system. The sun tracking and control system has the advantages of being simple in structure and convenient to use.
Description
Technical field
System of the present invention relates to one dimension real-time follow-up location and the protection of solar collecting device, relates in particular to solar heating with the one dimension real-time follow-up location of solar panel and protects.
Background technology
Along with sun power uses more and more extensively, the problem that occurs in its use procedure more and more receives publicity, wherein, throughout the year middle every day not in the same time the direct projection angle of sunlight all be among variation at any time, in this case, solar panel receives the efficient of sun power because the receiving angle problem just is greatly limited.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, one dimension sunshine tracking control system is provided, the orientation of adjusting solar panel makes it follow the tracks of the solar light irradiation angle, so that farthest absorb sun power, and guarantee that solar panel is all the time just facing to the sun.
To achieve these goals, the technical scheme that adopts of system of the present invention is:
The solar tracking control system comprises master controller, sunlight tracking sensor, one dimension DC servomechanism, solar panel, limit switch;
Described master controller, it is characterized in that using single-chip microcomputer as core controller, continue to receive the signal of sunlight sensor, control the one dimension DC servomechanism according to the parameter of setting sun power can be located by cell panel in real time, and receive limit signal so that the cell panel front all the time towards the sun;
Described sunlight tracking sensor, it is characterized in that to judge the angle relation of sunlight and solar panel, and testing result is exported to master controller, control the one dimension DC servomechanism after the master controller analyzing and processing and drive the solar panel rotation, make solar panel perpendicular to sunlight.The three forms the real-time closed-loop control system;
Described one dimension DC servomechanism, the real-time location that it is characterized in that realizing horizontal direction adopts DC servo motor and physical construction to combine, control solar panel and sunlight tracking sensor towards;
Described limit switch, it is characterized in that can be when cell panel rotation be about to arrive limit-switch positions, transmit signal to master controller to stop the motion of one dimension DC servomechanism.
Description of drawings
Accompanying drawing is principle of work schematic diagram of the present invention.
Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
With reference to accompanying drawing, system of the present invention comprises master controller, sunlight tracking sensor, one dimension DC servomechanism, solar panel, five ingredients of limit switch.
Master controller uses single-chip microcomputer as core controller, continues to receive the signal of sunlight sensor, control the one dimension DC servomechanism according to the parameter of setting sun power can be located by cell panel in real time, and receive limit signal so that the cell panel front all the time towards the sun.
Master controller has timing function, according to the time of program setting, makes system be at night dormant state with conserve energy, and timer activated system and started working daytime.
The state that master controller can detect sunlight tracking sensor automatically normally whether, when sensor broke down, the shielding following function was until trouble shooting.
The angle relation of sunlight tracking sensor judgement sunlight and solar panel, and testing result is exported to master controller, control the one dimension DC servomechanism after the master controller analyzing and processing and drive the solar panel rotation, make solar panel perpendicular to sunlight.The three forms the real-time closed-loop control system.
The one dimension DC servomechanism is realized the real-time location of horizontal direction under main controller controls, adopt DC servo motor and physical construction to combine, control solar panel and sunlight tracking sensor towards.
When limit switch was about to arrive limit-switch positions in the cell panel rotation, to stop the motion of one dimension DC servomechanism, just do not overturn over facing to the sun all the time by the assurance cell panel to master controller for the transmission signal.
Master controller receives the sunlight tracking sensor signal, controls the one dimension DC servomechanism after processing by analysis and drives the solar panel rotation, make its perpendicular to sunlight to reach the maximum absorbance of sun power; The one dimension DC servomechanism drives the sunlight tracking sensor rotation simultaneously, making its direction is current sunshine accurate location, the one dimension DC servomechanism is at the thing both direction bit switch of limiting, when solar panel rotates to when being about to arrive limit-switch positions, limit switch transmit signal to master controller to stop the motion of servo-drive system.
