Embodiment 1

[0040] Embodiment of the invention (refer to figure 1 with figure 2 ):Such as figure 1 with figure 2 The shown high-precision intelligent tracking system of the present invention includes a daylighting panel (1), a supporting main column (2) of the daylighting panel, a center line (3) of supporting the main column, a monitoring device (4), and a control device ( 5), the man-machine interface unit (6), the motor (7), and the adjustment mechanism (8) for changing the orientation of the lighting panel.

[0041] Such as figure 2 As shown, the high-precision intelligent solar tracking system is installed, at least the latitude and longitude of the solar tracking system, that is, the location of the daylighting panel (1) is given through the man-machine interface unit (6), and the control device (5) follows the known astronomical theory or The corrected sunrise and sunset time calculation formulas determine the location of the daylighting panel (1), the sunrise and sunset tim...

Embodiment 2

[0043] refer to figure 1 with figure 2 : When the wind speed and direction detector (not shown) in the monitoring device (4) detects that the wind force is level 7, it will feed back to the control device (5) in real time, so that the control device (5) judges that the wind is blowing, and commands The motor (7) drives the adjustment mechanism (8) of the daylighting panel (1) to move the actuator, and drives the mechanical part to push the daylighting panel (1) to control the daylighting panel (1) according to the wind direction signal indicated by the wind direction detector (not shown). ) facing the direction of the wind, and then stop.

Embodiment 3

[0045] refer to figure 1 with figure 2 On a certain day, at 10 o'clock in the morning, when the temperature detection element (not shown) in the monitoring device (4) detects that the temperature of the water flowing down on the surface of the daylighting panel (1) is about 7 degrees, it is fed back to the control device (5) in real time ), thus the control device (5) judges that it is raining, and instructs the motor (7) to directly drive the adjusting mechanism (8) of the daylighting panel (1) for azimuth change to act, and drives the mechanical part to push the daylighting panel (1) to rotate Automatically stop when the angle between the surface of the daylighting panel (1) and the centerline (3) of the supporting main column (2) is less than or equal to 60°.

Abstract

The invention relates to a high-precision intelligent sun-chasing system and a control method thereof. The system comprises one or a plurality of lighting panels with a sun tracking mechanism, a monitor apparatus, a control apparatus, a man-machine interface element, an adjusting mechanism changing the orientation of the lighting panel, a motor and / or a deceleration mechanism and has a plurality of special functions. The control method comprises that at least the latitude and longitude of the location of the lighting panel are determined and given through the man-machine interface element and the sun-chasing system is controlled to carry out optimized sun-chasing lighting motion according to the time of sunrise and sunset in various conditions.

Description

technical field [0001] The invention belongs to the fields of clean energy, manufacture and control of sun tracking devices, and in particular relates to a high-precision and intelligent sun tracking system and a control method thereof. Background technique [0002] The sun is a hot gaseous sphere, a huge, long-lasting, inexhaustible source of energy. As a clean energy source without any pollution, solar energy has attracted more and more attention and great interest from all over the world. So far, the utilization of solar energy has become increasingly widespread, including solar thermal utilization, photovoltaic utilization of solar energy and photochemical utilization of solar energy. From a long-term perspective, among new energy sources, photovoltaic power generation is the most potential strategic alternative power generation means. Relevant experts predict that by the end of this century, solar power will occupy 80% of the world's power structure. [0003] However...
