Embodiment Construction

[0043] Since the existing post-disaster search and rescue method lacks a positioning method for trapped persons, the embodiment of the present invention is based on a post-disaster search and rescue system, which uses the mobile phone terminal of the trapped person to send a distress signal, and receives the distress signal according to different locations. Time delay, calculate the position of the trapped person, and compare the strength of the signal received in each direction according to the different strengths of the distress signal received in different directions. The direction with the higher received signal strength can be considered as the buried depth of the trapped person is shallower (That is, the ruins from the direction outside the ruins to the trapped people have the least blockage), and rescue can be implemented from this direction. Further, through the penetration loss test of various buried materials on site, the transmission loss values ​​of various material...

Abstract

The invention discloses a post-disaster search and rescue terminal location method and system. The method comprises the steps of: selecting a position of a region to be detected; arranging a plurality of life detectors around the region in different directions; detecting the time delay and the strength of a distress signal received by each life detector; and determining a position and a depth of an embedded terminal according to the detection result. By adopting the technical scheme provided by the embodiment of the invention, the position and the depth of the embedded terminal and the position can be accurately and effectively detected, the position and the depth of the embedded terminal are immediately and efficiently judged, effective rescue guidance is provided for the post-disaster search and rescue personal, the rescue efficiency is greatly increased, and the survival rate of a trapped person can be ensured as the highest possible.

Description

technical field [0001] The invention relates to the technical field of post-disaster search and rescue, in particular to a post-disaster search and rescue terminal positioning method and system. Background technique [0002] Natural disasters have the characteristics of instantaneous occurrence, severe damage, difficulty in monitoring and forecasting, and far-reaching social impact. For example, destructive earthquakes, landslides and other disasters have caused huge harm and losses to national economic construction and people's life and property safety. Numerous cases of natural disasters at home and abroad prove that the technical level of post-disaster emergency rescue is extremely important for reducing disaster losses. [0003] At present, our country is still very weak in disaster emergency rescue technology, mainly relying on manpower, search and rescue dogs and life detectors for life detection to find survivors. The detection efficiency of manpower and search and r...
