Abstract:In order to solve the access requirements of massive devices in the power Internet of things, the cloud server centralized processing architecture gradually evolves to the edge computing mode, and the power Internet of things evolves into the four layer model of cloud, network, edge and end. According to the existing power business types and transmission needs, this paper analyzes the technical difficulties faced by edge computing in the power Internet of things, and proposes to adopt flexible scheduling based on time slots, and improve the end-to-end time delay in the edge computing network by combining the self slot structure and flexible time slot configuration; adopt the 5qi configuration and ARP priority scheme to improve the service guarantee effect in the power Internet of things, Using business security isolation is to ensure the safe operation of power business. At the end of the paper, it gives the construction and technical characteristics of edge computing gateway system based on 5g technology, and points out that it can make full use of the innovative technology based on 5g to improve the effectiveness and security of edge computing in the power Internet of things, so as to meet the needs of vigorous application of the power Internet of things.
