Disaster Rescue Communication System with Dynamic Risk Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During disasters, communication infrastructures are often destroyed, preventing information necessary for rescues from being transmitted between rescuers, leading to a lack of effective methods for direct communication and safe evacuation.
Innovation Solution
A method and apparatus that enable communication between rescuers by obtaining and sharing map information, location, and environmental condition data to determine disaster risk levels, identify optimal return paths, and transmit alert signals, using sensors and processors to facilitate device-to-device communication without infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct communication between terminals is implemented without base station, then communication capability in disaster area is improved, but information accuracy and reliability deteriorate due to lack of infrastructure support
Solution Approach 1:
The patent implements feedback mechanisms where rescuers continuously share location and environmental condition information through direct terminal communication. The system collects data from multiple rescuers, updates risk levels dynamically, and provides feedback to all participants, enabling adaptive decision-making without base station infrastructure.
Solution Approach 2:
The patent uses map information and risk level data as intermediary elements that mediate between rescuers' positions and safety decisions. These digital intermediaries carry critical information about environmental conditions and peer locations, enabling coordinated rescue operations without traditional communication infrastructure.
2Measurement precision
If multiple sensors are deployed for comprehensive risk assessment, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent employs sensors with multi-functional capabilities where each sensor serves multiple purposes. For example, location sensors not only determine position but also track movement patterns for risk assessment. Environmental sensors monitor both immediate conditions and trends over time, reducing the need for specialized sensors for each measurement type.
Solution Approach 2:
The patent combines multiple sensing functions into integrated apparatus that rescuers wear or carry. The system merges location tracking, environmental monitoring, and communication functions into a unified platform, reducing overall system complexity while maintaining comprehensive risk assessment capabilities through coordinated sensor operations.

AI summary
An operation method of a first apparatus for supporting disaster communications includes obtaining map information of a disaster area from a server; obtaining information on a location of the first apparatus, and obtaining environmental condition information of the first apparatus indicating a risk of an area to which the first apparatus belongs; obtaining information on a location and environmental condition information of a second apparatus located in the disaster area from the second apparatus; determining a disaster risk level indicating a risk level for each location in the disaster area based on the location and environmental condition information of the first apparatus and the location and environmental condition information of the second apparatus; and updating the map information by reflecting the disaster risk level.
