摘要
随着电力物联网的逐步推进,适应电网特征的边缘计算框架逐渐成为其中的关键技术。目前国家电网有限公司各专业信息系统存在感知信息不共享、未实现一次采集、难共享共用和智能管控等难题,迫切需要应用互联网思维和高效能边缘计算等技术手段,建设智慧物联体系。文章所述边缘计算框架立足于电力物联网边缘计算的功能需求,以国家电网有限公司电力物联网框架为基础,通过物模型、云边交互协议、规则引擎、智能生态等模块的设计,在边缘侧实现国网公司统一智慧物联体系“多元感知,多态接入,统一模型,统一物联”的目标。通过开展在功能性、非功能性、性能以及应用场景等方面的实验验证和试点建设,表明边缘计算框架在业务适配性和数据共享方面具有优势。
With the development of power Internet of Things,the edge computing become one of the key technologies suitable for power grid.At present,There are some problems in current information systems of State Grid Corporation of China such as lack of sharing perceived information,difficult one-time data collection,non sharing and intelligent control of the system.There is an urgent need to use Internet thinking and technology means including high-efficiency edge computing to build a system of intelligent things.The edge framework described in this paper is based on the functional requirements of the edge computing of power Internet of Things.Based on the theoretical framework given by the State Grid Corporation of China,modules such as the object model,cloud-edge interactive protocol,rule engine,and intelligent ecology,etc.are designed to achieve the design goal of the State Grid Corporation of China's unified smart IoT system:"multiple perception,polymorphic access,unified model,unified IoT".The experiment verification and pilot construction of its functionality,non-functionality,performance,and application scenarios demonstrates the advantages of edge computing frameworks in business fit and data sharing.
