摘　　要：针对关口电能量物联网终端上传费率电量的需求,对终端软件进行扩展设计,实现费率电量的读取、本地保存和上传等功能。对于分钟电量曲线容量大、嵌入式终端电子盘访问效率低的问题,采用信息压缩、按日分段文件存储、文件内部纵向和横向都采用2级结构排放等方式,提高信息处理的性能,达到快速访问的目的。考虑电量信息处理的严格性,采用多种手段实现信息的完整性和可追溯性。最后通过扩展IEC 60870-5-102协议的报文帧,将费率电量和最大需量信息上传给计量计费系统主站。所设计的软件在实验室和变电站现场进行联调检测和试运行后,各项功能和性能指标都符合要求,软件扩展设计达到预期目标。Aiming at the requirement of rates watt-hour data uploading for gate energy remote terminal,it is necessary to extend the design of terminal software that the reading,local saving and uploading of rate electric energy need be realized.Because of the large capacity of minute power curve and the low access efficiency of embedded terminal electronic disk,information compression and the vertical and horizontal two-level structure are adopted to store files by day in order to locate and access information quickly and improve the performance of information processing.Considering the strictness of terminal processing information,multiple means are adopted to realize the integrity and traceability.At last,IEC 60870-5-102 protocol is extended for rates watt-hour data transmission,and these data are uploaded to master station of power billing system.This software is tested and verified in laboratory and substation field,all functions and performance indicators meet the requirements,and the software extension has achieved expected goal.
