Abstract
The invention relates to an automatic sun tracking method and device, the method adopted is similar to the working principle of a sundial and comprises the following steps of: vertically arranging a pointer in the centre of a disk, using the shadow projected by sun to measure the position of sun, namely, detecting the position and direction of the shadow on the disk, and enabling the disk to rotate towards a direction opposite to the shadow to make the shadow finally disappear on the disk when the pointer points to the sun and the disk faces the sun. By the simple method, the sun can be automatically tracked. Moreover, an automatic sun tracking device is provided based on the method, wherein an upper, a lower, a left and a right solar panels are arranged at the front face of the disk; since the projected shadow may cause a voltage difference between two panels in bilateral symmetry or in longitudinal symmetry, once the state is detected by a detector, the orientation of a tracker is adjusted to make the shadow on the disk disappear, and at the same time, the symmetrical panels have no voltage difference, a motor stops rotation, and the disk faces sun; and thus, sun tracking is realized. The sun tracking device is simple in principle, skillful in structure, completely unmanned, high in tracking precision, and can be widely used in the development and the utilization of solar energy.

Solar panel, left and right sides solar panel also link to each other with accumulator up and down, are responsible for charging a battery, and guarantee that accumulator has sufficient electric weight, for package unit work provides power supply.
Shadow is fallen left and right sides solar panel on one of them the time, the voltage difference that left and right sides solar panel produces, left and right sides voltage-level detector is with this state notifying tracking control unit, tracking control unit sends instruction and makes card left-right rotation on surface level, make shadow fall up and down solar panel on one of them, the voltage difference that produces of solar panel up and down, voltage-level detector is with this state notifying tracking control unit up and down, tracking control unit sends instruction makes card rotate counter-rotation towards shadow up and down on vertical plane, so that shadow diminishes gradually up to till disappearing on the card.
When the cloudy day, card remains on the last position that the sun occurs of aiming at.
At post sunset, tracking control unit resets card, makes card be in position parallel to the ground, conveniently once more the sun is carried out tracking work.
The present invention is work like this: at first card is in the initial position on parallel ground, this position helps forming shadow most, shine upon card, pointer forms shadow on card, when two solar panels are on one of them about shadow drops on, left and right sides voltage-level detector detects this state, with the result notification tracking control unit, tracking control unit sends instruction and makes the card left-right rotation, make shadow fall up and down solar panel on one of them, the voltage difference that produces of solar panel up and down, voltage-level detector is with this state notifying tracking control unit up and down, and tracking control unit sends instruction makes card rotate the size of adjusting shadow towards the counter-rotation of shadow up and down, it is diminished gradually up to till disappearing on the card, this is that pointer points to the sun, and card is over against the sun, thus realize to the sun from motion tracking.When the cloudy day, card remains on the last position that the sun occurs of aiming at.At post sunset, tracking control unit resets card, makes card be in position parallel to the ground, conveniently once more the sun is carried out tracking work.
The invention has the beneficial effects as follows, thoroughly solve the problem of solar tracking, and principle is ingenious, simple in structure, unmanned is easy to safeguard fully, the precision height can effectively be followed the tracks of the sun, can be widely used on development and utilization, spacecraft, military affairs and the civilian installation of sun power.
