Abstract

The invention discloses a system and a method capable of automatically tracking solar radiation, which utilize local geographical information and time domain information, and interactions of the ecliptic plane, the equatorial plane and the horizontal plane to solve the problem of inaccurate tracking in different time domains, different latitudes and longitudes, areas in southern hemisphere and northern hemisphere and the like around the world. Moreover, the system can flexibly follow the direction of intense radiation according to local radiation conditions, and also can be changed into a dynamic sunlight tracking system used for mobile objects and devices to accurately track the sun according to time service information and positioning information emitted by a satellite.

Description

technical field [0001] The present invention mainly relates to the application field of solar energy, and specifically relates to a system and method for realizing accurate tracking of solar illumination and tracking during movement by applying the concept of astronomy and geography. Background technique [0002] The current tracking technology of sunlight is only passive tracking in a general sense. There is azimuth tracking, azimuth and zenith angle tracking. It is manifested in the large operating error and low precision of the system. If it is used in occasions that require light concentration, accurate focusing is an insurmountable obstacle in the face of the constantly moving sun. Especially when used in different time zones, latitudes and longitudes, southern hemispheres and northern hemispheres around the world, the cumulative error generated by such a system will increase accordingly, and it cannot be automatically and accurately adjusted, which is not conducive t...
