Abstract: With the development of the power Internet of things and the transformation of energy digitization, the application scenario of the power edge smart terminal is constantly expanding. AI chip has become one of the mainstream core devices of power edge terminal due to its intelligent analysis and parallel computing capability. However, how to select appropriate AI chip according to the application scenario through systematic analysis has become an urgent problem to be solved. This paper first analyzes the AI chip technology architectures and their advantages and disadvantages, the structural framework of the edge smart terminal is proposed, and the key technologies for the construction of the edge smart terminal are analyzed in detail. Finally, the customized selection scheme of the domestic alternative AI chip is proposed based on the typical power application scenarios. The AI chip power edge smart terminal proposed in this paper can effectively provide guidance for the design, development and application of power edge terminals, and has universal theoretical and practical value.
