嵌入式Linux平台下电力载波路由器的软件设计

针对载波电表集抄系统中,电力载波通信距离有限、抄收率低等问题,提出了一种应用于载波电表集抄系统的中继转发技术,并设计出应用此技术的电力载波通信路由器。采用多叉树遍历寻优算法实现了用户节点路径的自动寻优及自动更新,并在此基础上提供了网络和串口两种通信方式,以方便采集站对用户节点进行快速、准确、无误的数据抄收。

The software design of powerline communication route based on embedded Linux platform

In the carrier meter reading system,the electric power carrier communication distance is Limited,and meter reading has low rates.This paper proposes a set of copy used in carrier-meter relay system technology and designs power line carrier communication routers to apply this technology.The user node,the path to achieve automatic optimization,each node of the routing path of automatic updates,and providing Ethernet and serial port pairs of nodes in the data fast,accurate and correct meter reading function.
