A Safety Helmet for Coal Mine Workers Using Lora Communication

This paper presents a new smart safety helmet to ensure the safety and protection of coal mine workers.Traditional safety helmets provides only physical protection without real time monitoring and communication technology.For communication they majorly depends on wired communication and short range communication with the help of blue-tooth or WiFi.So the long range communication is very difficult for the conventional systems.To overcome this problem we proposes an advanced safety helmet integrating Lo-Ra (long range) communication technology.Lo-Ra enable long-range,low power and reliable data transmission even in deep underground mines.The proposed helmet is equipped with gas sensors and an impact detection system.Lo-Ra based solution can replace the outdated ,unreliable safety methods and significantly improves workers safety.
