Automatic tracking system for photovoltaic array brackets

Description

The automatic tracking system for photovoltaic array brackets is a precise device integrating mechanics, electrical control and software, designed to drive photovoltaic panels to move in real time following the sun. Its main components include:

1. Mechanical and drive systems: These are the bones and muscles of the system.

Support structure: including the main shaft, crossbeam and component brackets, it is the core load-bearing framework of the system.

Drive execution: The core is the reduction motor, which provides high-torque power and drives the entire array to rotate smoothly through mechanisms such as push rods or rotary reducers.

2. Sensing and Control System: This is the brain and senses of the system, and it is the key to achieving automatic tracking.

Controller: As the "brain", it is installed on site and is responsible for processing information and issuing action instructions.

Positioning and feedback: Angle sensors (such as encoders) provide real-time feedback on the Angle of the bracket to ensure precise positioning. The limit switch sets the physical movement range to prevent overrotation.

Input signal: The mainstream adopts astronomical algorithms. The controller calculates the theoretical trajectory of the sun based on the preset longitude, latitude and time, which is highly reliable. It can also be supplemented with a photosensitive sensor for real-time light tracking.

3. Auxiliary and Support Systems:

Power and Communication: The system is self-powered and equipped with communication modules (such as 4G/PLC) for remote monitoring, diagnosis and program upgrade.

Safety protection: This is a crucial link. The system integrates a wind speed sensor. In case of strong wind, it can automatically drive the array to a horizontal wind-resistant posture to reduce wind resistance. It also includes lightning protection devices and dust-proof and water-proof designs to ensure long-term stable operation outdoors.

In conclusion, this system, through intelligent control and precise coordination of mechanical component movements, not only enhances power generation efficiency but also possesses a complete self-protection capability.
