ARM处理器的远程抄表系统集中器设计

集中器是低压电力线载波集中抄表系统中的关键设备，能够通过下行信道自动抄收并存储各种具有载波通信功能的智能仪表、采集终端或采集模块以及各类载波通信终端的数据，同时能通过上行信道与主站进行数据交换。本文对集中器系统的总体结构进行研究，利用ARM芯片AT91SAM9260设计了电力远程抄表中的集中器。

Concentrator of Remote Meter Reading System Based on ARM

Concentrator is the key equipment of low-voltage line carrier centralized meter reading system. By downlink channel, it can au- tomatically read and store up all kinds of carrier communication function data from intelligent instruments, the acquisition terminals or acquisition modules and all kinds of carrier communication terminators. At the same time, it can exchange data with the main engine by uplink channel. The general structure of the concentrator system are studied by the paper, which uses ARM9 chip AT91SAM9260 to design concentrator of the electric power remote meter reading.
