The system architecture and function of an Internet+ based integrated intelligent power business hall are proposed aiming at the problems of incomplete system functions, weak information interaction, low service level, and scattered operation and management in the traditional electric power business hall. Firstly, the user requirements are analyzed to improve the service business architecture and network architecture of the intelligent business hall, and the functions that need to be realized by the intelligent business hall are analyzed comprehensively and systematically. Combined with the accurate matching function of the data of the intelligent power business hall, the reliability and stability of the service of the power business hall are effectively improved. This study will enhance the user experience, operational efficiency and the competitiveness of the electric power enterprises effectively compared with the existing research, and will provide reference for the future development of the electric power business hall.
