紅外與聲波協(xié)同生命探測平臺研發(fā)
摘 要：基于單一類型信息源的生命探測技術(shù)因自身缺陷無法完全滿足震后救援的需要。該文在介紹音頻、視頻和雷達生命探測技術(shù)工作原理的基礎(chǔ)上，分析它們各自具有的優(yōu)勢和存在的問題，給出異類多傳感器協(xié)同探測的優(yōu)勢與現(xiàn)狀，設(shè)計紅外與聲波協(xié)同生命探測平臺，給出平臺的結(jié)構(gòu)模型、傳感器的選擇策略以及相應的性能指標。主要實現(xiàn)紅外圖像與聲波信息的同步采集、分析與處理，兼具音頻生命探測和視頻生命探測的功能，彌補單一傳感器生命探測儀的不足，能得到更全面、更準確的生命體及救援現(xiàn)場信息，更適用于震后復雜的救援環(huán)境。

Abstract: Life detection technology based on a single type of information sources can’t completely meet the needs of the earthquake relief， because they can’t make up for their own defects. This paper introduces the existing life detection techniques including acoustic wave life detection， optical life detection and radar life detection. The advantages and existing problems of the three life detection techniques are also analyzed. The advantages and present situation of multi-sensor detection synergy technique are given. The life detection synergy platform is designed with infrared and acoustic wave in this paper. And the platform structure model， multi-sensor selection strategy and performance index are introduced too. Finally， the development direction of life detection technique based on multi-sensor synergy is forecasted. This platform can synchronously collect， analyze and process infrared image and acoustic wave， has the functions of audio life detection and video detection function， makes up for the deficiency of the single sensor life detector. It can get more comprehensive and more accurate information about the scene of rescue and living organisms， and it is more suitable for complex quake rescue environment.
Key words: life detection； multi-sensor synergy； infrared sensor； acoustic wave sensor
