Flood Detection from Vehicle Communication Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately detect and predict flood damage regions based on communication interruptions in vehicles, often mistaking other causes for submergence.
Innovation Solution
An information processing device that detects flood damage by analyzing abnormal communication interruptions occurring at specific altitudes and frequencies, using a control unit to identify and notify affected areas, and predict future flood expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If communication interruptions are monitored to detect floods, then flood detection capability is improved, but false detection from other communication failures increases
Solution Approach 1:
The system applies local quality by analyzing communication interruptions at specific geographic locations and altitudes. It distinguishes between interruptions occurring at low altitudes (indicative of flood conditions) versus high altitudes (less likely to indicate flood), thereby improving detection accuracy while reducing false positives from general communication failures.
Solution Approach 2:
The system segments the detection process into multiple criteria: monitoring communication interruptions, filtering by altitude threshold, counting occurrence frequency within a region, and verifying temporal patterns. This segmentation allows the system to distinguish flood-related interruptions from other communication failures through multi-condition validation.
2Measurement precision
If multiple communication interruption criteria are applied to detect floods, then detection accuracy is improved, but system complexity increases
Solution Approach 1:
The control unit performs multiple functions using a single integrated system: it monitors communication status, determines geographic position, evaluates altitude conditions, counts interruption frequency, identifies affected regions, and generates notifications. This multi-functionality reduces overall system complexity while maintaining high detection accuracy through coordinated operation of these functions.

AI summary
A control unit is provided which is configured to execute: acquiring an occurrence position of an abnormal interruption in communication with a vehicle and an occurrence position of an abnormal interruption in communication; detecting that a flood damage has occurred in the first area in response to an abnormal interruption in communication occurring a predetermined number of times or more at a position lower than a predetermined altitude in the first area; and outputting information on flood damage in response to detecting that a flood damage has occurred in the first area.
