适应变电站智能运维的智能协议转换方法

An intelligent protocol conversion method for intelligent substation operation and maintenance

为了实现多源数据的融合应用,需要将采用不同数据交换协议的在线检测装置接入变电站智能运维诊断平台。针对这种实际需求,提出了一种具有“对方协议自动识别功能”和“自适应配置互转协议参数功能”的智能协议转换方法。通过判断数据帧的多个特殊字段,以初步确定报文遵循的数据交换协议。进而,试探数据帧的命令类型字段和校验码字段,以最终确定对方遵循的数据交换协议。通过“通信报文A—数据库—通信报文B”的相互转换模式,实现了“一对多”、“多对一”以及“多对多”的数据交换协议的相互转换。详细介绍了所提智能协议转换方法的实现方案及其技术细节。所提方法弥补了传统“一对一”协议转换器存在的不足,为各类在线检测装置接入变电站智能运维诊断平台提供了一种便捷方法。

To realize the fusion application of multi-source data,online detection devices with different data exchange protocols need to be connected to the intelligent operation and maintenance diagnosis platform of a substation.In response to this need,an intelligent protocol conversion method with the functions of automatically identifying the protocol used in the other side of communication and adaptively configuring the parameters of the interconversion protocols is proposed.By judging multiple special fields of the data frame,the data exchange protocol followed by the data message is preliminarily determined.The data exchange protocol followed by the other side of communication is finally determined by tentatively testing the command type field and the check code field of the data frame.Through the conversion mode of"communication message A-database-communication message B",the protocol conversion modes of"one-to-many","many-to-one"and"many-to-many"are realized.An implementation scheme,and its technical details,of the proposed intelligent protocol conversion method are introduced in detail.The proposed method makes up for the deficiency of the traditional"one to one"protocol converter and provides a convenient method for all kinds of online detection devices to access the intelligent operation and maintenance diagnosis platform of a substation.
