Individual Soldier Vital Signs Monitoring System Based On WIFI Network

With the rapid development of biological sensor technology and communication technology,portable vital signs parameters measurement has gradually become a reality.Based on this,the system combines vital signs measurement and sound localization technology to construct an intelligent vital sign monitoring system in a wireless environment.The system consists of six parts,which are the vital sign sensor part,the control microcontroller and its peripheral circuits,the A8 processor and its peripheral circuits,audio interface circuit,the wireless communication module and the power supply part.Among them,the vital sensor has three indexes:body temperature,blood oxygen and heart rate;the control chip adopts STM32F103 based on CM3 core;the communication processor adopts AM3354 of Cortex-A8 core;the audio interface circuit adopts audio codec and bone conduction drive circuit;wireless communication module adopts the mode of Gigabit network to WIFI.In the software design,the vital sign sensor and audio collection function are realized,and the communication between the communication processor and the background computer is realized through the wireless communication module.The background computer uses LabVIEW to complete the debugging interface.The experiment has verified that the system has the advantages of reasonable structure,low power consumption and strong portability,which can be used as the basis for research and development of related systems.
