【摘要】 随着我国经济建设的高速发展,对矿产资源的需求日益扩大,各地也加强了对矿产资源的开采。由于现有的矿井生产环境恶劣,通信技术手段落后,恶性事故时有发生,给矿井的安全生产和井下人员人身安全带来严重危害,因此有必要采用先进的技术手段对矿井环境和井下人员进行实时监测,以及时发现矿井中安全隐患,并能在发生安全事故后对救援工作起到辅助作业,给救援提供精确可靠的井下环境信息和井下人员位置和体征信息。作为一种全新的信息获取和处理技术,无线传感器网络具有低功耗、低成本、分布式和自组织等特性,非常适合于井下监控。本文将Zigbee无线传感器网络技术引入矿井管理,利用无线传感器网络对矿井环境及矿工生命体征进行监测。本文在分析井下人员体征信息和环境信息检测需求的基础上,结合Zigbee无线传感器网络的特点,针对矿井巷道的特殊结构,提出了满足矿井人员体征检测需求的Zigbee网络拓扑结构和系统总体结构；并根据系统的总体结构,在分析现有Zigbee协议实现方法的基础上,利用CC243、MQ9和HK2000等设计了带环境监测功能的路由节点、便携式的井下人员体征信息采集节点和连接监控中心的汇聚节点；对监控中心的功能和需求进行了分析研究,利用SQLServer数据库设计了监控中心的监控软件。经过测试,该系统工作稳定可靠,可以通过监控中心实时监控井下人员体征信息和位置信息,也可以通过路由节点和井下人员携带的环境监测传感器及时掌握井下的环境信息。因此,采用Zigbee网络实现井下人员体征检测和环境检测是可行的。
【Abstract】 With the rapid development of economic, the demands of resource expanded, and the resource exploitation was forced spread of China. At the same time, the rough underground circumstances bring a great threat to physical and mental health of miners and safety production of mines. For the mine safety production and management, as well as the health of miners, it is necessary to monitor the underground environmental conditions and miners’vital signs. Bing a new information acquisition and processing technology, Zigbee has a lot good features of low power consumption, low cost, distributed and self-organization etc, which is very suitable for monitoring in mine. So we employed Zigbee to monitor the miners’vital signs and mine environments.A monitoring system of vital signs was applied based on the analysis of demands of miner vital sign monitoring, the features of Zigbee and the structure of mine, especially on potable vital sign collect node,routing node and Sink node use CC2431,MQ9 and HK2000. Also analysis the function of monitoring center,and designd the software of control center based on SQLSever. tThe test proved that the system operated stably and reliably; the vital signs of miner and the information of mine circumstance can be monitored though control center. It indicates Zigbee is suitable for mine communication and monitoring.
