用于复费率电能表计数器MR—2的通讯接口

A Communication Interface to the Intelligent RegisterMR 2 for Multitariff Watthour Meters

本文主要论述了用于电力管理部门的负荷控制终端与复费率电能表智能计数器ＭＲ—２的通讯接口的设计。该接口采用一个基于ＭＳＣ５１单片微机的接口电路来完成数据预处理和负荷控制终端与复费率电能表之间信号的接收、发送，通讯采用ＲＳ４８５总线，实现了电力部门的联网控制要求。

This paper discusses a comunication interface between the intelligentregister MR-2s and the load controlling terminal.The interface uses a circuit based onMSC-51 single-chip microcomputer to realize data processing and information transfer.The communication uses the RS485 bus. It has realized the networked control require-ments of power supply sections.
