| 摘 要： | 当前，一些大中型老企业仍大量使用集中安装的感应式电能表作为电能计量设备，且从各个电能表集中安装地点到企业调度中心都预留有大量的通讯电缆。因此，可以利用带RS485通讯接口的光电计数模块，对感应式电能表进行改造，利用计算机及通讯电缆组成电能量实时采集网络，实现低成本的远程自动抄表系统。本文介绍基于RS485串行口的自动抄表系统的工作原理，并给出了相应的硬件构成及软件。

| Abstract: | A great number of inductive ammeters fixed centrally are being used for electric management widely in some large enterprises,and many communication cables were pre-laid out from the places where the ammeters were fixed to the control centre.Therefore,An auto-electric management system was remade from the ordinary ammeters by using the photoelectric module based on RS485.The working principle and hardware and software design of the system were presented. |
