Embodiment Construction

[0015] In this technical solution, for the real-time tracking of the sun's rays, the system first completes the initial position calculation related to the sun's altitude angle and azimuth angle according to the longitude and latitude values ​​of the location. Then, the calculated data is stored in the database of the PLC programmable controller. Subsequently, the control signal is output to realize the start and stop of the stepping motor and the synchronous tracking of the light. The execution process of ray tracing is as follows: through the horizontal stepping motor fixed under the base of the device, the main shaft and its supporting bearing are driven to achieve horizontal rotation relative to the base of the device, thereby driving the composite power generation squares fixed on the left and right sides above the main shaft Support the moving bracket to realize the overall linkage in the horizontal direction; after the horizontal rotation is completed, the control modul...
