摘 要：Data gateway,completing data collection,storage,forwarding,protocol conversion and other functions,plays an important role in energy management system.Using hierarchical and modular design method,we design and implement a smart data gateway for energy management in this paper.However,it can be flexibly applied to other loT applications by adding the hardware module and the corresponding driver because we design the smart data gateway,aiming at IoT application.
