The Multi-Functional Interactive Intelligent Command System for Communication, Positioning, and Search & Rescue comprises intelligent wearable headgear (smart helmet and SCBA) and an interactive intelligent command system platform. Command personnel can comprehensively and accurately monitor rescue teams’ real-time status and surrounding conditions via the monitoring and command terminal, including vital signs, environmental parameters, location data, SCBA pressure, and other critical information. The system automatically triggers alerts and alarms upon detecting anomalies. Equipped with the intelligent wearable headgear, rescue personnel maintain clear visibility in smoke-filled and low-light environments, significantly improving search and rescue efficiency.
