无线传感器网络煤矿顶板压力在线监测系统

摘要

Lured by the high profits, colliery accident has occurred frequently. The root fall is often occurred. We can research the variation law by monitoring the colliery roof pressure, then we can prevent roof fall occurring. In this system, based on wireless net technology.a new wireless sensor networks which was applied in monitoring the colliery roof pressure was introduced . The wireless sensor nodes collect the data of roof pressure by pressure sensors. The data is transmitted to sink node by wireless signal based on IEEE802. 15. 4 and ZigBeeTM protocol stack. The sink node transmits the data to the monitor center by USB port. When the data of roof pressure are approach to the data of alarm, the wireless node, the sink node give the alarm signal, the monitor center gives the orange and red alarm information.%近年来我国煤矿安全事故时有发生,安全形势十分严竣;在采矿生产过程中最常发生的就是冒顶事故;通过实时监测顶板压力的变化,可以研究矿井顶板压力的规律,从而采取预防措施,有效地防止事故的发生;本系统采用无线传感网络的节点作为顶板压力致据采集的终端,采集顶板的压力变化数据;各节点采用基于TEEE802.15.4和ZigBeeTM协议栈的无线方式将数据传送到汇聚节点,汇聚节点采用有线通信方式将采集到的数据通过USB传输接口传输至地面的管理监控站,实现对矿井顶板压力数据的实时监控;当顶板压力数据接近或达到报警压力值,节点和汇聚节点发出卢光报警信息,同时地面监测站发出压力橙色或红色报警信息,促使安全部门采取有效措施,防止事故的发生,达到安全生产的目的.
