电能表与采集终端通信测试系统的设计

各地对电能表通讯规约进行了扩展,不同厂家对规约有不同的理解,导致电能表与采集终端之间出现了互联互通问题,对于负荷管理系统、自动抄表系统的推广应用产生了一定的影响。本文针对电能表与采集终端通信中常见的软件、硬件问题,分析了实物测试的缺点,阐述了通信测试原理和方法,提出了基于标准化平台的通信测试系统。该系统可自动模拟各种通信条件,分别对电能表和采集终端进行通信规约一致性测试。

Design of Communication Testing System for Watthour Meter and Data Collection Terminal

It is said that different producers had different apprehensions to the communica- tion protocol of the Watthour meter,and the communication protocol had been expanded for different purposes,this causes some problem about mutual communication.The communica- tion between the Watthour meter and the data collection terminal is very important to the load manage system and the automatic meter reading system.In this paper,the writers pointed out some common problems about the software and hardware of this system,and analyse the disadvantage of the real testing,then present the communication testing system based on the standardization,which can simulate all sort of communication condition automatically,then carry out consistency testing of Watthour meter and data acquisition terminal respectively.
