智能电表网络通信技术及通信协议探讨

摘要

This article embarks from the intelligent electric instrument network to the communication request, introduced the low-voltage power line carrier communication, micro-power wireless communication and RS-485 bus communication mode, and their advantages and disadvantages. To the current question that the communication protocol norm of the electric energy meter is not unified, introduced the IEC 62056 ＂Power Measurement - for meter reading, tariff and load control data exchange,＂ a series of international standards. This standard has unified the communication agreement based on that the interconnected model of open system requires Communications equipment language newspaper （DLMS norms ）.%从智能电表网络对通信技术的要求出发，对低压电力线载波通信、微功率无线通信和RS-485总线通信方式以及优缺点进行介绍。针对现行的电能表通信协议规范不统一的问题，介绍IEC62056《电能计量-用于抄表、费率和负荷控制的数据交换》系列国际标准，这一标准统一了基于开放系统互联模型要求的通讯协议-设备语言报文规范（DLMS）。
