摘要
为提高配电场域网节点间的传输速率和连通率,构建了具有高速电力线宽带载波和微功率无线通信能力的混合多径双模异构配电场域网。首先论述了该场域网的拓扑结构、组网过程以及维护机制。其次设计了一种滑动窗口加权平均链路度量方法,采用改进的跳数受限Bellman-ford最短路径算法计算混合多径路由,并使用最近最多使用策略对各节点路由进行分散更新。在此基础上设计了一种自适应多径并发数据传输动态决策算法。最后将构建的该场域网应用到配电信息采集系统中,并在实验室和工程现场对其性能进行了测试。测试结果表明,该场域网比单模场域网在提高抄收率和缩短抄收时间方面效果明显。
In order to improve the transmission and connection rates between the nodes of a power distribution field network,a hybrid multi-path dual-mode heterogeneous power distribution field network with high speed power broadband carrier and micro-power wireless communication capabilities is designed.First,the topological structure,the networking process and network maintenance mechanism of the field network are discussed.Secondly,a link measurement method based on a sliding window weighted average is designed,and hybrid multipath routing is calculated using a modified Bellman-Ford shortest path algorithm with limited hops and is refreshed in time intervals using the most recently used strategy.An adaptive multi-path parallel transmission dynamic decision-making algorithm is designed.Finally,the field network is applied to the power distribution information collection system,and tested in the laboratory and on site.The test results show that the dual-mode field network is more effective than the single-mode field network in increasing the copying rate and shortening the copying time.
