Data Transmission by Li-Fi in Coal Mining

Abstract

There are many dangerous threats in a coal mining industry such as gas explosion, and temperature and humidity variation which can be difficult to be monitored and controlled. In this paper, we proposed and designed a method to utilize the Li-Fi technology for data transmission which are equipped with sensors to provide real time situation stat to the coal miners to ensure their safety. One of the most dangerous gases in coal mining is the carbon monoxide (CO). Hence, specific type of sensor is used and connected to a core component which is the microcontroller and placed at different parts of the coal mine. When the concentration level exceeds a certain threshold value, the buzzer will be triggered, and the notification is sent to the central database to inform the workers. Li-Fi provides the solution for slow data transmission or data loss which enhances the safety and improve the working condition of labors in coal mining sectors.
