Edge Control for Disaster Response During Server Outages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to effectively maintain control functions for people, facilities, and infrastructure during and after natural disasters, particularly when power failures or communication interruptions occur, as they rely on pre-interrupted countermeasure information that may not adapt to changing disaster conditions.
Innovation Solution
A control device that estimates disaster occurrence using risk information, determines the necessity of control, and instructs edge devices to execute control instructions independently when communication with a server is interrupted, utilizing machine learning and reinforcement learning for improved adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If countermeasure information is transmitted periodically from server to control device, then control function can be maintained during normal operation, but adaptability to changing disaster conditions deteriorates when communication is interrupted
Solution Approach 1:
The control device performs preliminary actions by estimating disaster occurrence in advance using risk information and preparing control instructions before communication interruption. The device proactively determines necessary control measures and transmits instructions to edge devices prior to actual disaster impact, ensuring preparedness without waiting for real-time server guidance during critical moments.
Solution Approach 2:
The control device enables self-service capability by autonomously estimating disaster occurrence, determining control necessity, and executing control instructions without continuous server intervention. When communication is interrupted, the control device independently maintains control functions using locally stored risk information and pre-prepared instructions, eliminating dependency on external server responses during critical periods.
2Extent of automation
If control device waits for server response to determine control necessity, then centralized control is maintained, but response time to changing disaster conditions increases
Solution Approach 1:
The control device performs preliminary determination of control necessity by estimating disaster occurrence and pre-determining which control measures are needed before communication interruption. This advance preparation eliminates the need to wait for server responses during critical moments, as the control device already has identified which edge devices require control instructions and what those instructions should be.
Solution Approach 2:
The control device dynamically adjusts its operation mode based on communication status and disaster risk levels. When communication is available, it operates in centralized control mode receiving guidance from the server. When communication is interrupted or disaster risk is high, it automatically transitions to autonomous operation mode, dynamically determining control necessity and executing instructions without waiting for server responses.

AI summary
According to one embodiment, a control device includes one or more hardware processors. The one or more hardware processors are configured to: estimate occurrence of a disaster by using risk information indicating a risk of the disaster; confirm necessity of control of an electronic device from a server when the occurrence of the disaster is estimated; determine the necessity of the control according to the estimated disaster when a response is not transmitted from the server with respect to the confirmation of the necessity of control; and transmit an instruction of the control to the electronic device when it is determined that control is necessary or when a response indicating that control is necessary is transmitted from the server.
