【摘要】 近年来国内外灾难频发，我国救援队虽然在过去的历次灾害尤其是重大灾害的救援工作中发挥了巨大作用，但是由于装备不到位，阻碍了救援资源的合理有效利用，束缚了灾害救援能力的最大限度地发挥。专家指出我国救援队的建设仍然处于初级阶段。本文针对救援现场中对救援队员的生命信息采集问题，以嵌入式处理器为硬件系统核心，移植嵌入式Linux作为操作系统。进行了一种综合生命信息监测以及定位系统的初步研究。这一系统包括救援队员随身携带的终端装置(分机)和中心监测显示装置(主机)，能实时监测队员生理状态，并能提供救援队员的位置信息。其中分机系统是本文研究的重点整个分机系统可分为以下部分：(1)嵌入式处理器、(2)扩频通信、(3)定位、(4)生理监测。本课题采用SAMSUNG公司性价比较高的ARM 9处理器芯片S3C2410为硬件系统核心，设计了系统硬件主要是系统核心板和扩展板各部分电路。采用了扩频通信芯片组，扩频通信具有其它通信方式所不具备的一系列优点，特别适用于复杂地形通信。实现了满足系统要求的无线数据传输。定位使用了全球定位卫星(GPS)技术，实现了嵌入式系统条件下接收GPS信息。生理信息包括心率、体温、呼吸和血氧饱和度，其中本文主要研究了对心率和体温的检测。更多还原

【Abstract】 The domestic and international disaster takes place frequently in recent years, though the rescue group of our country has played a great role in the rescue work of the past all previous calamities, especially great calamity, but because equip it uncompletely, hinder the rational effective use of rescuing resources, full play to the maximum extent fettering the calamity and rescuing ability. The expert points out that the construction of the rescue group of our country is still at primary stage. This paper gathers the question to the life information which rescues the team member at the scene to rescuing, regard embedded processor as the systematic core of the hardware, transplant embedded Linux as the operating system. We carried on a kind of comprehensive life information monitoring and preliminary research of the navigation system. This system including rescuing team membering carry-on terminal device(extension) and in the center monitor and show the device (the host computer), can monitor team member’s physiological state in real time, and can offer the position information of rescuing the team member. Among them the extension system is the focal point.The whole extension system can be divided for the following part: (1) embedded processor, (2) Spread Spectrum Communication, (3) GPS, (4) life information monitor. We adopt SAMSUNG Company ARM 9 processor chip S3C2410 as hardwares cores, mainly is the key board of system after designing the systematic hardware and expand every part of circuit of board.we adopt chips of Spread Spectrum Communications, Spread Spectrum Communication have a series of advantages that other communication ways do not possess, especially suitable for the complicated topography and communicate. Have realized wireless data transmission of the systematic demand. Positon system uses the whole world to orient the technology of the satellite (GPS), has realized that receives GPS message under the embedded systematic condition. Physiological information including rhythm of the heart, body temperature, breathing and blood and oxygen saturation lever, among them the measuring of rhythm of the heart and body temperature of main research of this text.更多还原
