摘要
为解决电力物联网中海量设备接入诉求,云服务器集中处理架构逐渐向边缘计算模式演进,电力物联网演进为云、网、边、端四层模型。本文根据现有电力业务类型和传输需求,分析了电力物联网中边缘计算面临的技术难点,提出采用基于时隙的灵活调度,并结合自时隙结构和灵活时隙配置等方案改进边缘计算网络中的端到端时延;采用基于5QI配置及ARP优先级方案提升电力物联网中业务保障效果,采用业务安全隔离是保障电力业务安全运行。文章最后给出了基于5G技术的边缘计算网关体系架设和技术特点,指出可以充分利用基于5G的创新技术,提升电力物联网中边缘计算有效性和安全性,满足电力物联网蓬勃应用的需要。
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.The 5QI configuration and ARP priority scheme are adopted to improve the business guarantee effect in the power internet of things.The business security isolation is adopted to ensure the safe operation of the power business.At the end of the paper,the erection and technical characteristics of edge computing gateway system based on 5G technology are presented,and it is pointed out that edge computing efficiency and security in the power Internet of things can be improved by making full use of the innovative technology based on 5G,so as to meet the needs of the booming application of the power internet of things.
