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.
