摘　　要：农网智能配变终端采集配电变压器现场各种数据,是农网智能化、自动化中不可缺少的前端元件。基于多年在配电网自动化系统中积累的经验,设计开发了一款完全符合Q/GDW615-2011农网智能配变终端功能规范和技术条件的农网智能配变终端。设计方案采用RS485总线和多处理器协作技术,处理器之间采用MODEBUS规约完成数据共享。独特的母板设计,采用了软硬件结合方式实现了功能插件即插即用和自动识别技术。工程人员可以根据用户需求设计技术方案,便于系统后续扩容升级,为用户降低反复投资费用。Rural intelligent distribution transformer terminal collects transformer state data and other intelligent terminals, such as watt-hour meter, collector, etc., which is the front element of the distribution automation system for rural power grid intelligent and automation. This paper summarizes the technical experience in the distribution automation system accumulated over the years. It designs and develops a rural network intelligent distribution terminal fully consistent with Q/GDW615-2011 functional specification and technical conditions. The design scheme adopts RS485 bus and multi processor collaboration technology. MODEBUS code is applied for data sharing between multi processors. Motherboard adopts special design method. The software and hardware are combined to realize automatic identification technology and plug and play technology. Engineering staff can design technical solutions according to user＇s need, which is convenient for subsequent expansion and upgrade of the system, and to reduce repeated investment cost for users.
