基于电力线载波技术的居民小区自动抄表系统

The Electric Metre Auto Data-collecting System of Residential Quarters Based on Power Line Carrier Technology

文章介绍了一种以Neuron芯片为核心，以电力线为传输媒介的LON技术；讨论了居民小区自动抄表系统中，选用以LonWorksPLT－20电力线收发器构成的LON网络；同时给出了抄表系统中原机械式电表的改造原理以及载波节点、集中器节点的软硬件设计原理。

This article presents a LON technique which adopts Neuron Chip as main processor, and power line as trans.mission medium. The LON network using LonWorks PLT-20 power line transiver, which is applied in the electric metre auto data-collecting system of residential quarters is discussed in this article. The renovation principle of the machinical electric metre used in the system and the design principle of the hardware and software of carrier nodes and centralization nedes are also presented.
