摘　　要：为了可靠地监测井下设备的运行状态,延长设备无线监测网络的生命周期,采用一种新的路由协议代替Zigbee中的AODV协议.将煤矿井下液压支架运行状态无线监测系统中的监测节点分布简化为链式2层拓扑结构,应用Free-space无线信号传输模型寻找使该拓扑结构每回合能耗最小最优簇数,同时利用设备排列的有序性引入虚拟地址的方法来分簇,提出了一种基于Zigbee的虚拟地址能量有效分簇路由协议(ZVAEECP).仿真结果表明:该协议比Zigbee的AODV协议至少提高50%的网络生存周期,丢包率最大为0.87%,是相同情况下AODV的12%.ZVAEECP协议比AODV具有更长的网络生存周期和更高的可靠性,且路由表只需维护少数几条信息.该协议可以扩展应用到具有相似拓扑的其他设备中,适合在井下设备监测中应用.In order to reliably monitor the running status of underground equipment and prolong the life cycle of wireless monitoring network,a novel routing protocol was applied to replace the AODV protocol of Zigbee.A Zigbee-based virtual address energy efficient clustering routing protocol（ZVAEECP） was presented,which simplifies the distribution monitor nodes into two layers chain topology in the underground wireless monitoring system of hydraulic support.The optimal number of clusters was searched using a Free-space radio signal transmission model which can minimize total consumed energy of the sensor network per round,and the cluster was divided by utilizing the orderly arrangement of equipment to lead into the virtual address.The results show that comparing with the AODV protocol of Zigbee,ZVAEECP protocol increases by 50% or more network life time,and the maximum packet loss rate is 0.87% which is 12% as AODV in the same case.ZVAEECP protocol has longer network life cycle and higher reliability than AODV,while routing table only maintains a small number of information.The protocol can be extended to the other equipment with similar topology and appropriately applied in underground equipment monitoring.
