Chatura Suraksha Kavacha – The Smart Safety Helmet for Mine Workers

Abstract

The underground mines all over the world are adversely affected by various hazards including gaseous explosions, landslides, fire hazards, etc. This leads to the significance of safety for the mineworkers. The proposed work talks about safety helmet which is used to avoid the accidents, which will cause in the workspace with a low-cost sensor. The smart helmet has been produced to assist miners operating in the mining industry. Many risky incidents commonly occur in the mining sector, many of which result in life-threatening injuries or death. A miner's helmet is one of the most regularly used safety equipment for mineworkers hence it must be loaded with some more advanced features. With the use of different sensors, the smart helmet will be able to identify catastrophic situations such as harmful gases like Carbon-Monoxide (CO), methane (CH4), liquified petroleum gas (LPG), and natural gases. The existence of the helmet on the worker’s head is detected by an infrared sensor. Each sensor has a threshold value that, if exceeded, causes the buzzer to activate and the LEDs to illuminate, signalling the miners and supervisors. The ESP32 cam module fitted in the miner’s helmet allows the mining officials to monitor the worker continuously. Furthermore, an Emergency Button has been implemented, which, when pressed, sends an emergency signal to the higher authorities outside the mines. A mobile application has also been created to display all of the data supplied wirelessly from the sensors. As a result, the proposed smart helmet protects miners from upcoming accidents.
