【摘要】 针对传统自动抄表系统存在的多种计量设备相互通信困难的问题,提出了一种面向自动化抄表系统的智能消息语言(SML)。分别阐述了SML的基本概念、结构及其在网络结构中的定位,分析了SML语言标准中的消息簇组成格式、封装和编码方式等。最后,结合电力抄表系统的应用实例,给出了SML语言在电力自动抄表系统中的各种数据传输格式。通过引入SML语言,可以使传输过程规范化,从而为我国有关标准的制定提供了依据。更多还原

【Abstract】 It is difficult for traditional automatic meter reading system to communicate among multiple metering devices,the smart message language(SML) of orienting automatic meter reading system is proposed.The language describes the data transmission and parameter definition in meter reading process with unitary protocol.Basic concept and structure of SML and its position in network structure are presented,and the composite formats of message cluster,packaging and encoding pattern in SML standard are analyzed.Combining with the applicable example of the electricity meter reading system,various data transmission formats of SML in such system are given.Through introducing SML,it is useful to make the transmission process standardized,thus provides basis for our country to work out relevant standards.更多还原
