Primarily deployed in indoor rescue operations with severe signal obstruction—such as large shopping malls, tunnels, and underground facilities—and adaptable to complex high-risk environments including chemical plant explosions and earthquake-induced structural collapses. The system delivers meter-level precise positioning and real-time trajectory tracking of personnel.

1.Equipment Perception Layer Comprises:

Wearable Vital Signs Monitor (Smart Wristband) – continuously tracks heart rate, body temperature, and other physiological parameters

Portable Bluetooth Audio-Visual Alarm Light – activates high-intensity strobe and audible alerts during hazardous conditions

Interactive Intelligent Single Firefighter System for Safety Monitoring, Environmental Sensing, Positioning, and Search & Rescue – captures real-time location/status data with bidirectional communication capability

Function: Continuously acquires personnel biometrics and environmental data.

2. Data Transmission Layer

Employs Communication Repeater (relays and amplifies signals for reliable connectivity in obstructed environments) and Network Gateway (manages network topology and uploads aggregated data), leveraging narrowband self-organizing network architecture to ensure stable, resilient data transmission under demanding conditions.

3. Data Application Layer

Centered on the Rear Command and Monitoring Terminal, which visualizes operational data to enable real-time situational awareness, proactive risk identification, early warning alerts, and data-driven command decision support.
