The Research Or Rescue Group's Life Information System Based On Embedded Platform

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.
