The distribution terminal has played an increasingly important role in the process of building the smart grid, function has also been enhanced. According to the construction of distribution network with terminal functional diversification and large data storage requirements, a design idea based on Berkeley DB is proposed in this paper. The rapid storage, query and delete operation of history information is realized in the embedded operating system. Build platform to compare and analysis with simple file storage, the result shows that the design has obvious advantages in the storage efficiency, query and delete speed, cpu usage. The distribution terminal unit has been successfully applied in Beijing and other places. The result of application is reliable and stable and can meet user needs.
