Research On Mine Emergency Rescue Communication System Based On Zigbee Technology

Due to the complexity of the mine environment, many security risks, coal mine accidents occurred frequently in our country, resulting in significant economic losses and casualties.How build after the accident emergency rescue communications system to improve the efficiency of disaster relief after the accident, reduce economic losses and casualties, caused widespread concern of the whole society.Existing mine safety monitoring system, although the use of a variety of ways to achieve the right positioning and monitoring of underground personnel to improve production safety protection.But accident damaged safety monitoring system, especially in monitoring communications equipment, so that the original security monitoring communication system can not meet the need for rescue work.This paper studies the ZigBee network technology. ZigBee has low power, low cost, self-organization, support a large number of nodes, supports a variety of network topologies, fast, and reliable technical characteristics.Come to the ZigBee wireless network technology to build the mine emergency rescue communications system feasibility and advantages.Combined voice and video transmission under conditions of wired communications have high bandwidth, long distance and wireless communication system operating convenience, but the lack of reliability and bandwidth characteristics.Combined with Zigbee wireless network technology and wired ADSL communications technology, proposed an emergency rescue communications system, to achieve a cable voice, video and data transmission in4km.Through the study of Zigbee wireless network configuration between the terminal nodes, coordinator, gateway and mine rescue base and ground command center. Deduced that after a mine accident emergency rescue communications system able to meet the voice, video communication needs and tracking rescue personnel and collecte environmental parameters for underground and to quickly build an emergency rescue communications system in the rescue site, improve the efficiency of the mine rescue.It has an important reference value to build an emergency communication system under the special circumstances quickly.
