文章研究了微功率无线集抄的档案管理新方法,用于解决微功率无线中心节点需要下发子节点地址档案来建立网络关系的问题。通过信标帧广播搜表、扩展的场强收集命令、扩展的游离节点入网等方式,将子节点地址与其下挂的485电能表地址对应关系建立并反馈给中心节点,使得中心节点不下发子节点地址也能自组网通讯。降低了组网出错概率,保证电能表数据采集顺利进行。 This paper studies a new file management method for micro-power wireless aggregation, which is used to solve the problem that micro-power wireless central node needs to issue child node address file to establish network relationship. By means of beacon frame broadcast search list, extended field strength collection command, extended free node access and so on, the subnode address is established with the corresponding 485 energy meter address and linked to the central node, so that the central node does not issue child Node address can also be self-organizing network communications. Reduce the network error probability, to ensure the smooth data collection meter.
