Embodiment Construction

[0044] With the development of integrated energy, the access of massive integrated energy equipment and the continuous enrichment of emerging services have gradually exposed the problem of unbalanced spatio-temporal distribution characteristics of power distribution business, and task offloading is currently the solution to the uneven spatio-temporal distribution characteristics of power distribution business. One of the commonly used means of balancing, but at present, task unloading is simply to offload terminal tasks with high load to terminals with low load according to the load status of the terminal, without considering the unloading cost generated when the task is unloaded, resulting in the existing power distribution The Internet of Things still has technical problems of poor stability.

Abstract

The invention provides a cloud-side cooperative task unloading method and device for the power distribution Internet of Things, and the method comprises the steps: enabling a first edge computing terminal based on a to-be-unloaded task and a second edge computing terminal for receiving the to-be-unloaded task, according to the task amount of the to-be-unloaded task and the communication bandwidthbetween the first edge computing terminal and the second edge computing terminal, to calculate the task unloading communication cost from the first edge computing terminal to the second edge computingterminal, and according to the task amount of the to-be-unloaded task and the operation frequency of the second edge computing terminal, calculating the task unloading operation cost of the second edge computing terminal, and then using the calculated task unloading comprehensive cost corresponding to the second edge computing terminal as a judgment condition according to the task unloading communication cost and the task unloading operation cost; therefore, the second edge computing terminal with the minimum unloading cost is determined as the final to-be-unloaded task receiving terminal, and the technical problem of poor stability of the existing power distribution Internet of Things is solved.

Description

technical field [0001] The present application relates to the technical field of cloud computing, and in particular to a method and device for unloading cloud-edge collaborative tasks of the power distribution Internet of Things. Background technique [0002] At present, the power distribution Internet of Things uses the cloud-side-end architecture to support the access of massive integrated equipment and the development of emerging services in the distribution station area. The characteristics make the cloud center and edge computing terminal a general computing device. Due to the advantage of geographical location, the edge computing terminal is responsible for data collection and processing at the terminal layer, and responds quickly to real-time services; the cloud center relies on the advantages of massive computing resources to realize massive business. Concurrent processing and computational processing of complex businesses. [0003] However, with the development of ...
