摘要
为了对协议的实现进行优化,本文从应用层的帧种类与功能、数据链路层帧结构和对象模型三个方面对DLMS/COSEM与DL/T协议进行了对比。在此基础上提出了一种以增加flash空间为代价来兼容DLMS/CO-SEM与DL/T协议的SOC(System On Chip)电能表设计方案。测试结果表明,电能表能基本满足DLMS/COSEM和DL/T协议的要求。
In order to optimize the implementation of the protocol,this paper compares DLMS/COSEM with DL/T from frame types and functions of application layer,frame structure of data link layer and object model.On this basis,an SOC electric meter compatible with protocol DLMS/COSEM and DL/T at the expense of adding flash space is designed.After testing,it is shown that the meter basically meets the need of protocol DLMS/COSEM and DL/T.
