Event-driven message interaction method of electric power internet of things

Abstract

The invention discloses an event-driven message interaction method of an electric power internet of things. The method comprises the following steps: firstly, modeling a cross-organization or cross-department collaborative service process in an Internet of Things management platform and an edge Internet of Things agent / intelligent terminal of the electric power Internet of Things; then defining execution semantics of the service process resource model, then proposing an analysis mechanism of a process execution engine to the service model, and finally realizing message interaction in the micro-service system architecture, thereby realizing message interaction. According to the invention, the problem of direct mapping and interaction between large-scale distributed sensors, power intelligent terminals and service data streams can be effectively solved.

Description

Technical field [0001] The invention relates to a message interaction method, in particular to an event-driven message interaction method of the power Internet of Things. Background technique [0002] After SG-186 and SG-ERP, the State Grid Corporation of China, based on the terminal, uses its own and leased networks and information systems to fully cover the various production links of "generation, transmission, transformation and distribution". The power Internet of Things has begun to take shape and support "National, provincial, and local" three-level dispatch, power transmission and transformation status monitoring, power distribution automation, power information collection, power marketing, and many other production businesses. With the continuous evolution of technologies such as "clouds, big things, moving intelligence," wireless access, and the Internet, the Internet of Power Things is currently undergoing a transition from a vertically integrated closed model to an ope...

Problems solved by technology

[0004] (2) The power grid business is facing the improvement of real-time, interconnection and security requirements. In the traditional way, all terminal data is uploaded to the cloud platform of the business master station for centralized processing, which will lead to long transmission delay, bandwidth and energy consumption. The waste will not only cause performance degradation of some delay-sensitive applications, but also bring huge processing pressure to the backbone communication network and background business system

[0006] At present, the software and hardware platform architecture of the edge IoT proxy device has been built, and the corresponding general functions and special functions have also been developed and entered the testing stage. In the actual application process, although the heterogeneous original data is encapsulated into a unified The event format provides users with a standardized interface. However, due to the informatization personnel's unfamiliarity with the power business, there are still problems in the design of IoT applications that do not fit well with the business, or are hosted on smart terminals that are distributed across regions. Business process applications cannot respond as quickly as possible to various perceived events, etc.
