摘 要: 针对电厂设备运行状态在线监测系统中无线传感网络(wireless sensor network,WSN)的节点部署具有较大随意性的问题,提出以网络有效总功耗、有效通信覆盖、有效生存周期等作为评价指标,以能效和覆盖为约束,构建规范化的确定性分层网状网MESH部署的WSN. 在此基础上,设计了基于信息路由的独立中继节点透明模式下的随机接入算法;实现在恶劣环境中规范化确定性部署下极低功耗多跳通信。实验结果说明:该算法能随意增加中继跳数,减少平均消耗电流(部分装置超过100%),并且便于构建标准化的大型监测网络。
关 键 词: 通信网络技术;中继节点;低功耗;分层MESH;规范确定部署;随机接入

Abstract: In order to solve the problem of node deployment of wireless sensor networks (WSN) for equipment condition online monitoring system in power plants having large arbitrariness, evaluating indicators such as valid total power consume, active communication overlap, valid life circle of networks and so on were approved. Then the WSN of hierarchy MESH network of standard deterministic deployment was constructed under the constraint of valid power consumes and communication overlap. Based on this deployment, the random access algorithm under the transparent mode of independence relay nodes based on information routing was designed, and ultra low power consume multi hop communication under industrial standard deterministic deployment was realized. Experiments showed that when number of hops was increased, the network could work normally, and mean current consume could be decreased (some devices were decreased more than 100%), and it was easy to construct standard large scale monitoring network.
Key words: communication network technology; relay nod; low power consume; hierarchy MESH; standard deterministic deployment; random access
