【摘要】 瓦斯和温度检测是煤矿安全生产中重要的工作,针对煤矿井下布线不方便的特点,提出了利用射频芯片的无线传感器网络来采集和传输瓦斯与温度信息的系统架构。系统由移动节点和固定节点组成。移动节点和固定节点、固定节点与固定节点之间采用无线技术传递信息。固定节点中的汇聚节点收集相应范围内的瓦斯与温度数据后通过载波方式将其传递给地面监控中心。实现了灵活组网、低开销、扩展性好和实时监测的功能,实施效果较好。更多还原

【Abstract】 Mining gas and temperature detection is an import work in mine safety production.Mining gas and temperature decting and transmiting system frame is presented based on wireless sensor network using RFIC,aiming at inconveniently wring feature.The system consists of stationary and mobile sensor nodes.Wireless communications are used between the mobile node and mobile node,and also between stationary node and stationary node.The sink nodes collelct the mining gas and temperature information and transmit it to the ground monitor & control center.The system is flexible networking,high expansibile,and lower cost.Real-time monitoring is achieved.The implementation effect is good.更多还原
