Abstract

The invention relates to an edge computing task allocation method for real-time online monitoring service of electric power Internet of Things, and belongs to the technical field of real-time online monitoring of the electric power Internet of Things. The method comprises the following steps: firstly, establishing a real-time online monitoring service task allocation model based on edge calculation; secondly, for an edge node task queuing problem in a particle swarm algorithm, setting a hybrid priority based on an EDF to queue tasks. For the problems that the particle swarm optimization algorithm solves the defects of a discrete problem and is easy to locally converge, a task allocation solving method based on the improved discrete particle swarm optimization algorithm is provided; simulation results show that the algorithm provided by the invention can effectively allocate real-time online monitoring service edge calculation tasks, further reduce service time delay and effectively improve the comprehensive performance of a real-time online monitoring system.

Description

technical field [0001] The invention belongs to the technical field of real-time online monitoring of the Internet of Things, and in particular relates to an edge computing task assignment method for real-time online monitoring services of the Internet of Things. Background technique [0002] With the continuous improvement of the intelligence of substations, there are more and more types of services that need to be connected to substations. Various services have different requirements for communication network quality, access location, and security.
