基于CAN总线和ZigBee的矿井瓦斯监测系统设计

摘要

针对目前煤矿瓦斯监控系统信号传输的弊端,提出一种新型煤矿井下瓦斯气体浓度监测无线网络的设计方法.系统主要包括ZigBee便携式采集终端和CAN通信节点.便携式采集终端具有显示瓦斯气体浓度和报警功能,并将信息通过ZigBee无线网络传输给CAN总线,最终将信息传给井上监控中心,实现对全矿的瓦斯实时监测.%Considering the signal transmission shortcomings of coal-mine gas monitoring system, new wireless network design for coal-mine gas concentration monitoring was proposed to have the ZigBee portable collection terminal capable of displaying gas concentration and alarm and CAN communication nodes included and the information transmitted to CAN bus and the monitoring center to achieve a real-time monitoring of the coal-mine gas.
