The problem A SMART HELMET FOR IMPROVISING SAFETY IN MINING solves

A smart helmet has been developed which includes various features such as the two way communication, detection of the hazardous gases, providing notification in the case of helmet removal, collision (miners are struck by an object), panic switch for emergency situations, continuous monitoring of the environmental conditions such as temperature and pressure in the mining industry and GPS is provided to track the location of the miner.
We have implemented an ultimate protective helmet that comes with many sensors for various detection and analysis. Firstly, the hazardous gases are detected using gas sensors.
Whenever the poisonous gas is detected the solenoid valve gets opened for providing oxygen supplements. The second hazardous event was classified as a miner removing the mining helmet off their head. An IR sensor was developed successfully to determine when the helmet is off the miner’s head.
The third hazardous event is defined as an event where miners are struck by an object against the head with a force exceeding a certain level by using force sensor which is used for detection.

Challenges we ran into

In the existing system mining helmet ensures to protect the miners head from several injuries. Being aware of the environmental condition becomes a challenging part of the existing system. Since the helmet is too heavy, uncomfortable to work with the miners tend to remove the helmet off their head. In case of its removal miners are prone to unsafe conditions.
There is no existing smart helmet that can study the environment and make decisions to sustain worker protection. Oxygen supply is not provided for the miners in case of poisonous gas leakage. Establishing a hurdle free communication environment is the biggest challenge the mining organizations face.
