利用手机信号进行生命探测的研究与系统设计

本文针对灾后紧急救援的需要,提出了一种新的生命探测方法,利用手机跨越位置更要发出请求信号的原理,效仿蜂窝网络移动台混合定位(TDOA/TOA)技术,通过主动探测地震灾害中被压、埋人员身上携带的手机信号,间接搜救遇难人员。该系统不但能探测到无网状态下待机的手机,并能将其定位在一定的范围内,为地震救援提供了可靠的帮助。

A novel life detecting system research and design based on cell phone detecting

In order to meet the rescue requirement after a disaster,a novel life detection system was proposed in this paper.It was based on the principle that a cell phone will give a register signal before switching to another cellular network.TDOA/TOA technology was used to locate the buried person by means of detecting the cell phone taken along.Owing to the initiative detecting technology,the system can not only detect and locate the cell phone with out the cellular network,but also provide a reliable method to search and rescue lives after an earthquake.
