Research on Intelligent Power Management and Control Technology of Electric Vehicle Based on Edge Computing

摘要

With the development of smart grid, Internet of things devices are widely used in the field of power management and control. The diversity of IOT equipment types, characteristics and functions not only integrates detailed big data, but also challenges the real-time, compatibility and big data processing ability of system management and control. Among them, electric vehicle is a kind of electrical equipment with random power consumption and strong impact in the current power grid. This paper studies an embedded edge computing technology in the power Internet of things system, proposes an implementation scheme of edge computing based on vehicle terminal, and designs a vehicle terminal hardware platform with ArmCortex-A7 and EMMC as the computing core, which is based on Embedded Linux system and socket virtual machine. The technology develops an edge computing platform to meet the simultaneous operation of multiple data applications, processes the massive intelligent power consumption data of electric vehicles nearby, avoids the communication channel blockage caused by massive data transmission, and meets the special requirements of power Internet of things for rapid response and accurate execution. Experiments show that the proposed technology can not only provide safe and fast control mode, but also make the system have stronger power consumption information big data acquisition ability, and has advantages in low bandwidth and low delay applications.
