ABSTRACT
A ZigBee-based wireless mine supervising system is presented here.. This scheme uses intelligent helmets and ultra-low-power nodes of wireless sensor network. The program adopts ZigBee wireless technology to build wireless sensor networks, realized real-time surveillance with early-warning intelligence on methane, temperature, humidity and heartbeat in mining area, to reduce potential safety problems in coal production.
Miner's helmet is extensively deployed in large and medium-sized coal mines, for their flexibility of light weight and low power. ZigBee based wireless sensor networks are used due to their remote environment monitoring capabilities. Such a network can easily collect sensor data and transmit them by radio.
Combining these two advantages we have designed a smart new helmet , which enable the helmet as a mobile node of ZigBee wireless sensor networks, gathering parameters from underground timely and quickly.
