基于ZigBee的井下人员监测系统设计

Design of Underground Personnel Monitoring System Based on ZigBee

获取矿井下人员的实时信息,对煤矿安全生产具有十分重要的意义。以ZigBee无线通信技术为基础,设计一种井下人员定位基站,其中包括CAN通信及数据处理装置,并利用极大似然估计算法精确地定位井下人员的位置,实现了地面管理中心对井下人员的定位监测和管理,为煤矿安全管理和生产提供重要保障。

Access to real-time information of mine personnel, has the great significance to the coal mine safety production. This thesis is based on the ZigBee wireless communication technology as the foundation, design a kind of underground per- sonnel positioning base station, including CAN communication and data processing device, wireless RF receiver, using the maximum likelihood estimation algorithm to locate precisely the location of underground personnel. In order to achieve ground management center of underground personnel positioning monitoring and management, and provide important safe- guards for coal mine safety management and production.
