Smart Controller Fallback for Network-Disrupted Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control platforms for electronic devices face challenges in maintaining uninterrupted operation during software updates or outages, particularly in industrial settings where network disruptions can lead to system instability and potential malicious instruction signals, impacting reliability and performance.
Innovation Solution
A control arrangement with a smart controller that generates substitute instruction signals using a machine learning model, isolated from the outer controller, to ensure continuous operation of electronic devices by imitating the behavior of the outer controller and maintaining a steady-state or safe operating mode, even during signal traffic abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control algorithms are migrated to the edge and more control functionalities are concentrated at the outer controller, then system performance and reliability are improved, but the risk of system instability and malicious instruction signals increases when network disruptions occur
Solution Approach 1:
The patent introduces an intermediary component (outer controller) between the inner controller and the network. This outer controller acts as a mediator that receives high-level commands from the network and translates them into safe, validated instruction signals for the inner controller. During network disruptions, the outer controller's validated instruction signals prevent malicious signals from reaching the inner controller, thus resolving the contradiction between improved reliability through edge migration and the risk of harmful factors during network disruptions.
2Adaptability or versatility
If software updates and maintenance are performed on the outer controller, then system functionality is improved, but uninterrupted operation of the electronic device cannot be guaranteed
Solution Approach 1:
The patent applies preliminary action by pre-validating and caching instruction signals in the outer controller before network disruptions occur. The outer controller maintains a buffer of validated instructions that can be executed during software updates. This allows the inner controller to continue operating with pre-validated signals while the outer controller undergoes maintenance, thus resolving the contradiction between software update capability and uninterrupted operation.
3Speed
If wireless communication technologies like 5G are used for real-time data transfers, then network synchronization and latency are improved, but network outages and interferences can still impair device ability to receive control commands
Solution Approach 1:
The patent implements beforehand cushioning by creating a buffer layer in the outer controller that stores validated instruction signals. When wireless network outages or interferences occur, this buffer provides cushioning that allows the inner controller to continue receiving valid commands without interruption. The outer controller's validated signal buffer acts as a protective cushion against network failures, resolving the contradiction between high-speed wireless communication and reliable command reception.
