Abstract
To have dynamic emergency escape instructions to guide the trapped workers, underground emergency escape system based on the internet of things is studied. It uses nodes to monitor the concentration of gas in coal mines. The nodes, distributed in the mine, are the component units of the wireless network. If the concentration exceeds the warning line, it broadcasts an emergency signal to the whole network and calculates the next safe evacuation direction through the data collected by real-time algorithm and displays the direction on the LED dynamically. By then, the network shows a number of security paths pointed by all the individual nodes connected together. So it most likely avoids the dangerous areas consisted by disaster nodes and guides people to flee the danger zone.
