Edge Node Update via Auxiliary Unit for Continuous Data Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing edge computing systems, data communication between an edge node and a cloud server is disrupted when the master unit is updated, leading to incoherent information being reported to the cloud server, which is unacceptable in scenarios with high monitoring requirements.
Innovation Solution
A method and apparatus for updating an edge node that uses either an auxiliary unit or a master unit as a target module to perform data interaction with the cloud server, ensuring continuous data communication and smooth updates by shifting the responsibility of updating the master unit to the auxiliary unit and vice versa.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the master unit is updated directly, then the module update is completed, but data communication between the edge node and cloud server is disrupted
Solution Approach 1:
The patent introduces an auxiliary unit as an intermediary component that takes over data communication responsibilities during master unit updates. The auxiliary unit acts as a mediator between the updating master unit and the cloud server, ensuring continuous data interaction without disruption. This resolves the contradiction by providing a backup communication path that maintains reliability while enabling safe module updates.
2Reliability
If the master unit is updated, then the to-be-updated module is refreshed, but incoherent information is reported to the cloud server
Solution Approach 1:
The patent implements preliminary actions by having the auxiliary unit prepare and maintain data communication capabilities before the master unit update begins. The auxiliary unit is pre-configured to take over communication responsibilities, and version information is pre-synchronized. This ensures that when the master unit updates, the auxiliary unit can immediately maintain coherent information reporting to the cloud server, preventing information inconsistency while minimizing update time loss.
3Reliability
If an auxiliary unit is introduced to handle updates, then data interaction continues during updates, but the system structure becomes more complex
Solution Approach 1:
The patent applies universality by designing the auxiliary unit with multi-functional capabilities. The auxiliary unit can perform both data communication tasks and master unit update execution. It serves as a universal component that can switch between different operational modes: normal data interaction mode and update execution mode. This reduces the need for separate dedicated components, thereby maintaining reliability while limiting the increase in system complexity.
