The intelligent fire safety system, based on information technologies such as big data, the Internet of Things, cloud computing, and artificial intelligence, integrates prevention and management, effectively warning of safety hazards such as electrical, gas, and fire water. The system relies on modular intelligent sensors to intelligently perceive low-voltage distribution systems, gas systems, and fire water systems. Through smart fire terminals, physical state data is transmitted to the data center via the Internet of Things. Through intelligent analysis of big data, it determines whether the monitored object has security risks and notifies users and government regulatory departments of security risks in real time. The alarm information service is implemented by a third-party service organization based on alarm data to identify and rectify hidden dangers, achieve hidden danger prediction and timely investigation, and eliminate fire hazards in their infancy. Truly realizing the principle of 'prevention first, combination of prevention and control'.
