System and method for smart city firefighting and automatic extinguishment based on internet of things large model

A system for smart city firefighting and automatic extinguishment based on an Internet of Things (IoT) large model, comprising an emergency monitoring and management platform configured to:

• obtain emergency monitoring data;
• determine emergency protection data for a protection region based on the emergency monitoring data and regional characteristic data;
• determine, based on the emergency protection data, an emergency control parameter, the emergency control parameter including a protection activation condition, an extinguishment target, and a protection-extinguishment parameter;
• send, based on the emergency control parameter, an extinguishment control signal to an extinguishment device installed in the protection region through an emergency monitoring sensing network platform to drive the extinguishment device to perform emergency extinguishment by the emergency control parameter, including:
• controlling rotation of a spray head of the extinguishment device to orient toward the extinguishment target;
• and
• in response to satisfying the protection activation condition, activating the extinguishment device to perform extinguishment based on the protection-extinguishment parameter with a preset coverage area and a preset spray flow rate.
