Fllowing the development of the household distributed energy generation, as a part of AMI(Advanced Metering Infrastructure), further studies are need to set up a smart measurement system which can be integrated with existing electric energy metering automatic system（AMR）. By studying the method of household distribution network is introduced and system architecture and information exchange standard and key technology, this paper presents the overall solution that include the model and algorithm. We develop some key parts of software and hardware, a simulation system is set up to test and verify the effectiveness of the solution.
