1.Equipment Perception Layer

Serving as the foundational data source, this layer integrates the following sensing devices:

Electronic Pressure Gauge (monitors SCBA cylinder pressure)

Portable Bluetooth Audio-Visual Alarm Light (delivers high-intensity strobe and audible alerts during hazardous conditions)

Toxic Gas Detector (measures concentrations of hazardous gases)

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

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

Continuously monitors environmental hazards and firefighter physiological status in real time.

2.Data Transmission Layer 

Built on LoRa-based self-organizing network technology, this layer employs: 

Communication Repeater (relays and amplifies signals to maintain robust connectivity in complex, obstructed environments) 

Network Gateway (aggregates field data, uploads to command center, and manages network topology) 

Ensures stable, low-latency, and resilient data transmission under demanding operational conditions. 

3. Data Application Layer

Centered on the Rear Command and Monitoring Terminal, this layer performs intuitive data visualization and intelligent analytics, transforming raw field data into actionable insights to empower timely command decisions and enable proactive risk early warning.

Designed for high-risk operational environments including firefighting emergencies, petrochemical facilities, and disaster rescue operations. Specifically engineered for complex scenarios such as large-scale structural fires, hazardous chemical leaks, high-temperature dense smoke conditions, and structurally unstable sites, the system delivers critical life-safety protection for interior attack firefighters.
