With the continuous expansion of the scale of photovoltaic power plants and the increasing complexity of technology, the safe and stable operation becomes crucial. The solar photovoltaic power plant safety early warning system emerges as the times require and becomes the key defense line to ensure the efficient operation of the power plant and prevent accidents. It is like the "intelligent brain" of the power plant, which can detect potential safety hazards in advance through real-time monitoring and data analysis of the operation state of the power plant, and timely issue warning signals, so as to gain valuable processing time for the operation and maintenance personnel and effectively reduce the probability of accidents.

A plurality of sensors are installed on the bottom side of the first mounting bracket. Alarm devices are installed on both sides of the first mounting bracket. A camera is connected to the top side of the first mounting bracket through the first rotating mechanism and the second rotating mechanism.
