摘要

为实现灾后废墟内幸存生命的高精度探测

设计了一种智能型便携式生命探测仪。基于非色散红外吸收式CO2传感器检测狭隙空间内的CO2体积分数

通过间隔采样来完成体积分数变化率的计算;基于嵌入式微处理器设计了模糊推理机

利用救援专家的先验知识

根据狭隙内的CO2体积分数及其变化率探测幸存者的存在和气息的强弱

检测结果通过显示屏和声光报警反馈给抢险人员。实验结果表明:该探测仪合理考虑了存在幸存者时CO2体积分数的实时变化特性

充分利用了救援专家的先验知识

有效提高了狭小空间内的幸存者探测和搜救精度。

Abstract

In order to realize high precision detection of survivor life after the earthquake

an intelligent portable life detector is designed.The volume fraction of CO2 is detected by the infrared absorption sensor

and the volume fraction change rate is calculated through interval sampling technique.A fuzzy inference engine is designed based on embedded microprocessor

and the chances of survivors values is reasoning concluded by using the prior knowledge of rescue experts

according to the narrow slot in CO2 volume fraction and rate of change.The information is communicated to the emergency personnel through sound and light alarm and LCD.Experimental analysis shows that the detector fully takes into account the characteristics of CO2 volume fraction changes real time when there are survivors.The prior knowledge of rescue experts is used reasonably

and the precision of search and rescue of survivors in the small space is improved effectively.
