摘　　要：为提高配用电场域网连通率和传输效率,构建了具有高速电力线载波和微功率无线通信能力的配用电双模异构场域网。首先,详细论述该场域网的拓扑结构、中心结点组网过程、游离节点动态入网流程和网络动态维护机制。其次,设计混合路由表的路由度量机制与改进的层数限制最短路径路由算法。最后,依据实时混合路由表,网络节点自适应选择最优链路以最佳速率进行数据传输。实验结果表明,该场域网提高了智能电表与中心节点的连通率,减少了网络层级,提高了传输效率。To improve the connection rate and transmission efficiency of an electric field network for power distribution grid,a dualmode heterogeneous field network for power distribution with high-speed power line broadband carrier and micro-power radio frequency communication capabilities is designed in this paper.First,the topological structure of the field network,networking process at the central node,dynamic network connection process of free nodes,dynamic maintenance mechanism of the network are discussed in detail.Secondly,routing measurement mechanism for creating a hybrid routing table,and the improved layer limit shortest path routing algorithm are designed.Finally,each node in the network can transmit data by adaptively choosing the best link at the best possible data rate according to the real-time hybrid routing table.Experimental results show that the field network increase the connection rate of the smart meter to the central node,thereby reducing the network hierarchy and improving the transmission efficiency.
