废墟搜中的音频生命求救信号分析研究
|
摘要
废墟搜救机器人在灾害搜救领域发挥了越来越大的作用,受到世界各国学者的关注,我国在这方面的研究还处于起步阶段。灾害发生后,处在废墟中的受困人员会发出多种有用的音频求救和生理信号,有利于帮助搜寻受困人员;但这些信号往往比较微弱。文章分析了最具特征的心跳和呼吸音频信号,研究其数字模型。这些信号的特征分析对采集到信号的识别带来依据,为救援工作带来极大帮助。
The rescue robots are playing more and more important role in the field of disaster rescue,aroused intensive attention among scientists and scholars in worldwide.The research in China is still in its initial stage.When a disaster happen,a variety of useful audio distress signals may be sent out by the people trapped in ruin.The signals are often too weak to get easily.This paper analyzes the heart and respiration sound signals which have obvious characters and researches their mathematical models.Analysis of these signals will be helpful for the signal recognition and rescue.
