摘要
为改善煤矿瓦斯监测能力,提出并实现了基于Z igBee协议的层次型无线传感器网络的拓扑控制机制。层次型网络拓扑结构的建立过程包括上层骨干网的建立和下层基础网的建立,其中上层骨干网络的建立又包括协调器建网和簇首节点入网2个过程。设计了网络节点的地址分配策略,分配过程包括协调器给簇首节点分配地址和簇首节点给端节点分配地址。针对网络运行过程中可能出现的网络拓扑结构变化问题,如端节点离开或加入网络,设计了相应的处理机制。实验室和煤矿现场试验结果都表明所提出的拓扑控制机制能顺利生成网络,且能对出现的一些拓扑结构变化进行相应的处理。
In order to improve the coal mine gas monitoring and measuring capacity, the paper provided and realized the topology mechanism of the gradation wireless sensor network based on the ZigBee protocol. The establishment procedure of the gradation network topological structure should include the establishment of the upper layer backbone network and the establishment of the low layer basic network. Whereas the establishment of the upper layer backbone network would also include the two procedures of the coordinator network establish- ment and the cluster head endpoint joining network. The ID distribution strategy of the network node was designed. The distribution proce- dure should include the cluster head endpoint distributed ID provided by the coordinator and the endpoint distributed ID provided by the cluster head endpoint. According to the variation problems of the network topological structure occurred during the network operation procedure, such as the terminal separated from or entered into the network, the relevant handling mechanism was designed. The lab and the coal mine site test results showed that the topologiy control mechanism provided could soccessfully generate the network and could have the relevant handling of the some topology structure variation occurred.
