针对煤矿复杂的工作环境及安全生产的要求,研究了一种基于zigbee技术的无线传感网络与光纤通信网相结合的煤矿安全监测及人员定位系统。系统实现了井上人员实时监测井下区域的瓦斯浓度,并实时跟踪定位井下人员,方便工作人员有效地管理矿井的安全工作。文章介绍了zigbee技术的特点,提出了无线传感网络系统分层运作的机制,分析了井下人员定位功能的实现方法、环境参数采集及传输的过程,并对系统的软件设计流程进行了全面介绍。
In view of the complex working environment and safety requirements of coal mines, a coal mine safety monitoring and personnel positioning system based on zigbee technology and wireless fiber optic communication network is studied. The system realizes the uphole personnel to monitor the gas concentration in the downhole area in real time and track and locate the downhole personnel in real time to facilitate the staff to effectively manage the mine safety work. This paper introduces the characteristics of zigbee technology, puts forward the mechanism of hierarchical operation of wireless sensor network system, analyzes the realization method of underground personnel positioning function, the process of environmental parameter acquisition and transmission, and a comprehensive introduction to the software design flow of the system .
