Abstract: In view of problem that traditional gas detecting methods only continuously monitor some key positions of mine, an intelligent miner lamp with gas alarming based on ZigBee was designed. The miner lamp is taken as a mobile node of ZigBee network, uses LED as illuminant and lithium battery as power supply, which has functions of gas detection, wireless positioning, ZigBee communication, charge management and protection. Test results show that actual parameters and communication function of the miner lamp meet design requirements and can realize omnidirectional coverage for underground gas detection.
