Detailed Description

The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.

The utility model discloses realize solar energy automatic tracking device based on machine vision discernment, include in outdoor slewing mechanism 4, total controller 2, vision camera 3 and the pole setting 5 of locating on bottom plate 13, the bottom plate position is in the rear below of sun 7, as shown in fig. 1.

The rotating mechanism 4 comprises a horizontal rotating motor 8, a vertical rotating motor 9, a support frame 10 and a support 13, the support 13 is installed on the bottom plate, the support frame 10 is installed on the support frame 13, a vertical transmission shaft 11 is installed on the support frame 10 through an upper bearing seat and a lower bearing seat, the vertical rotating motor 9 is installed at the bottom of the support frame 10 through a motor base, an output shaft of the vertical rotating motor 9 upwards passes through the lower end of a coupling connection transmission shaft 11, the horizontal rotating motor 8 is installed at the upper end of the transmission shaft 11 through the motor base, the lower end of a rotating arm 12 is fixedly installed on a horizontal rotating shaft of the horizontal rotating motor 8, and a solar panel 1 is installed at the upper end of the rotating arm 12, as shown in fig. 1.

In the structure, the rotating mechanism 4 comprises rotation in the horizontal direction and rotation in the vertical direction, the rotation in the horizontal direction and the rotation in the vertical direction are respectively executed by the horizontal rotating motor 8 and the vertical rotating motor 9 to complete the rotation in the horizontal direction, the rotation in the horizontal direction drives the solar panel 1 to rotate within the range of 0-180 degrees on the vertical surface, the rotation in the vertical direction drives the solar panel 1 to rotate within the range of 360 degrees on the horizontal plane, and the combination of the two movements can realize the all-directional movement of the solar panel 1.

A backing plate 14 is mounted on a bottom plate in front of the support 13, a support rod 15 and a master controller 2 are arranged on the backing plate 14 in front and at the back, the vision camera 3 is mounted on the top of the support rod 15 through a camera frame, and the shooting visual angle of the vision camera 3 faces to the front lower part; the upright 5 is mounted on a base plate 14 in front of the vision camera 3, and the sunlight shadow 6 generated by the illumination of the upright 5 by the sun 7 is mapped on the base plate 14 behind the upright 5, as shown in fig. 1.

The utility model discloses the operation step of automatic tracking sunlight does:

1. the light of the sun 7 irradiates the upright post 5 to generate a solar shadow 6, the solar shadows 6 with different lengths can be generated due to different sunlight irradiation angles, and the maximum projection length of the solar shadow 6 is set to be L and input into the master controller 2.

The maximum projection length L determining method comprises the following steps: the maximum pole projection length L is determined by day monitoring and if the detected projection length L > L at the time of use, it (L) is changed to the maximum projection length.

2. Once the sun shadow 6 appears (in a sunny state), the vision camera 3 can immediately shoot the sun shadow 6 with a certain projection length l, and the vision camera 3 converts the l-length sun shadow 6 into a digital signal and transmits the digital signal to the master controller 2.
