A coal mine gas inspect system based on wireless sensor network

基于无线网络技术,探讨一种应用于矿井瓦斯监测的无线传感器网络的设计。节点采用高性能的ATm ega128为主控制器,CC2420为无线收发单元。网络采用一种集中控制式的主从结构,根据无线传感器网路的特点及监测环境的特殊性,给出了用于煤矿瓦斯监测的无线传感器网络系统方案。与传统的监控系统相比,该系统具有结构灵活、可扩展性强、测量准确等特点。

Based on wireless net technology, a new wireless sensor network which was applied in monitoring the colliery environment was introduced. This design took ATmega128 as the central controller, CC2420 as the radio unit. This network adopted a master-slave rela- tion topology that used centralized control. According on the feature of wireless sensor network and the particularity of monitoring environ- ment, proposes WSN system for monitoring mine coal gas. Compared with conventional monitoring system, this system is characterizes by structural flexibility, great extensibility and accurate measurement.
