ENHANCING MINE SAFETY WITH WIRELESS SENSOR NETWORKS USING ZIGBEE TECHNOLOGY

摘要

In coal mines, whenever explosions occur, the rescue work is done by rescue workers without any prior knowledge of the environmental condition inside coal mine because the mine monitoring systems may be destroyed or damaged. This makes the life of rescue workers very risky. It also takes some time for the rescue workers to reach the spot. According to the proposed system, a ZigBee network controlled automatic robot has been developed for assisting rescuers. This system works even when a ZigBee node fails. Whenever any explosions occur, the robot automatically detects the explosion, finds the explosion location and enters the coal mine tunnel well before the arrival of rescuers. It finds the location of accident, searches for survivors to give them first aid at right time and informs the rescue team about environmental conditions and about the survivors inside the coal mine.
