摘要
根据自动抄表系统(AMR)的需要,运用DLMS/COSEM通信协议设计了具有互操作性的电子式智能电能表。重点分析了通信协议在电能表上的实现方法,利用面向对象思想建立了电能表模型,运用分层原理从物理层、链路层和应用层分别对协议栈进行了设计。测试结果表明,电能表符合DLMS/COSEM通信协议,满足自动抄表系统的发展需要。
According to the needs of automatic meter reading system, an interoperability Electronic Energy Meter was designed with Communication Protocol DLMS/COSEM. This paper focus on how the communication protocol method was used in Watt_hour Meter, using object-oriented thinking the power meter instrument model was established, and with hierarchical principle, from the physical layer and link layer to application-level design methods were presented, After testing,it is shown that the meter achieve the Communication Protocol DLMS/COSEM and meet the need of AMR.
