Intelligent search and rescue system in special environments such as disasters

Abstract

The invention discloses an intelligent search and rescue system in special environments such as disasters, which comprises a body surface feature extraction device, a vital sign extraction device, a voice feature extraction device and a network transmission device which are in communication connection in sequence, and is characterized in that the body surface feature extraction device adopts a GRU network model for transmission and storage; the voice feature extraction device comprises a sound acquisition module, a sound feature extraction module and a sound analysis processing module which are in communication connection in sequence, the sound analysis processing module is provided with a noise database comprising various environment sounds, and the environment sounds in the noise database are eliminated through wavelet analysis for noise reduction processing; the network transmission device comprises a Zigbee network communication module, a network transmitting module, an unmanned aerial vehicle network relay module and a network receiving base station which are in communication connection in sequence. According to the method, a comprehensive scheme for multi-feature extraction of the wounded in special environments such as disasters is provided, the real state of a disaster site is restored, and a basis and artificial intelligence aid decision are provided for efficient development of rescue work.

Description

technical field [0001] The invention relates to the technical field of logistics support, in particular to an intelligent search and rescue system in special environments such as disasters, and in particular to a multi-feature extraction device and method for wounded in complex environments. Background technique [0002] Earthquakes, mountain landslides and other geological disasters require large-scale rescue to rescue the trapped people and protect the safety of life and property. There are also potential safety hazards for large-scale rescuers, such as aftershocks after the earthquake and ground subsidence after mountain landslides. The continuous occurrence of such dangerous situations may bring new safety accidents. If necessary measures are not taken, rescuers will May become new victims. [0003] Of course, the existing rescuers will also carry out the necessary safety training, but they will also be powerless in the face of large-scale disasters. Especially after a...
