A relief system based on phone detecting and positioning is studied and designed.For detection problem,life detection module of this system uses signals of phones to detect life indirectly in affected areas,and then outputs a detection report.For rescue problem,rescue module analyzes the detection report and locates the target phone by using triangle centroid algorithm.Then the module calculates the shortest path by using Floyd algorithm.This system is designed to use phone detecting and positioning technology,which is more effective and costs lower than directly detecting.The system also combines positioning and shortest path rescue,which gets faster and better.
