摘要
将电力线载波通信网络应用于智能电网中,有效延长通信距离是亟待突破的技术难题。为此,提出一种基于IPv6的低压电力线载波树型路由机制,子网节点通过支持IPv6地址自动分配的分布式地址分配策略来构建载波网络层次转发树模型。中继节点以MAC头中的目的地址进行下一跳路由转发,并结合IPv6适配层中的Mesh头实现多跳路由寻址。在层次转发树中,中继节点只需存储与其子节点数相当的信息项即可实现子网内路由信息的快速生成。搭建了电力载波通信配电网树型拓扑结构测试平台,测试结果表明,该树型路由控制机制能够以较小的时延进行IPv6数据包的多跳转发,并有效延长了电力线载波通信距离。
To effectively extend communication distance of power line communication networks used in smart grid is a key technology to be broken through. A new tree routing mechanism based on IPv6 is proposed for power line communication network. A network model of power line carrier hierarchical forwarding tree is constructed by designing IPv6 address auto allocation method. Next hop transmitting is completed through short address of MAC layer, and multi-hop routing is realized according to mesh header of adaptation layer by relay node. Each relay node only needs to maintain a few forwarding entries with the same number as its son-nodes to quickly generate routing information in subnets. A test platform about tree network topology of distribution network for power line communication is built, and test results show that tree routing mechanism can effectively realize IPv6 packets＇ multi-hop transmittal with a small delay and extend distance of low-voltage power line communication.
