Summary
This study introduces a novel mine rescue monitoring framework using hybrid Wi-Fi and fiber optic communication with wearable sensors. This system enhances safety for rescue personnel in hazardous underground environments.
Area of Science:
- Mine safety engineering
- Wearable sensor technology
- Underground communication systems
Background:
- Mine rescue operations face significant risks due to hazardous underground conditions.
- Challenges include damaged infrastructure, unreliable communications, heat stress, and hypoxia.
- Existing monitoring systems may not adequately address these complex environments.
Purpose of the Study:
- To propose and validate a prototype mine-rescue monitoring framework.
- To integrate a hybrid communication architecture with flexible wearable sensing modules.
- To enhance the safety and effectiveness of mine rescue operations.
Main Methods:
- Developed a communication architecture combining Wi-Fi for local data and optical fiber for long-distance backhaul.
- Created flexible wearable sensing modules: a temperature sensor and a photoplethysmography (PPG) optoelectronic module.
- Utilized polyaniline/graphene-polyvinyl butyral composite for the temperature sensor and ITO/Ag/ITO for the optoelectronic module.
Main Results:
- The temperature sensor demonstrated a clear, temperature-dependent resistance response.
- The optoelectronic module exhibited low sheet resistance and good electrical continuity under bending.
- Preliminary validation of component-level performance for mine rescue applications.
Conclusions:
- The proposed hybrid communication and wearable sensing framework shows promise for mine rescue.
- Component-level validation supports the feasibility of this integrated approach.
- Future work will focus on end-to-end system verification in simulated or field conditions.
