摘要:
为解决高校节能监管系统配电站分布离散，各站内计量点规模不大时的远程集抄问题，以STM32F103处理器为核心，扩展了DL/T645-2007协议的定义，设计支持3级中继功能的电力载波（power line carrier，PLC）小型路由器。路由器以载波芯片为圆心，实际通信距离为半径，构成等效的直抄、一级中继、二级中继和三级中继蜂窝模型，并以此为基础，建立一个逻辑上以路由器为根节点，各级蜂窝覆盖圆为层次的多叉树遍历查询结构，实现了中继路由图的建立和自动中继转发抄表。所设计的中继技术在低压电力载波通信和智能水表远程集抄领域得到了成功应用，可以低成本地替代RS485以实现能耗系统的远程抄控。
Abstract:
Aiming at the small scale of the remote reading of power meters in the scattered power stations of the energy-saving supervision system of colleges and universities, the mini-router with power line carrier (PLC) was designed based on STM32F103, which expanded the definition of DL/T645-2007 protocal in order to support three-stage relay functions. The router took the PLC chips as the center and the actual communication distance as the radius, forming the equivalent cellular model with direct reading, primary relay, secondary relay and third-stage relay. Also, on this basis, a multi-tree traversal inquiry structure was established, logically, with the router as the root node and all levels of cellular coverages as the hierarchy, so as to correctly establishd the relay route diagram and achieved automatic relay meter-reading. And the relay method has been successfully applied in the field of low-voltage PLC communication and intelligent water-meter reading system, which could replace RS485 to realize remote control and data collection in the energy consumption system at a low cost.
