Msp430-based Human Signal Detection And Alarm Systems

At this stage in China, it has gradually entered the aging society,the safety of the elderly is the one of most particularly problem of aging staff structure which will face by the whole society. For the rising of the people's living standards,we gradually ascende requires to the quality of life and the demand for health and so on,a portable,suitable for individual families and abnormal physiological monitoring equipment is needed which can protect their own health or the safety of their families.Determine the basis physilolgy and pathology in this paper,it designs a human signal detection and alarm system basised on the MSP430.It uses the continuous non-invasive measurement in this system,monitoring arterial oxygen saturation,body temperature and pulse this three important human physiological signals,judging the data processing to it,in order to achieving real-timestatus. monitoring of human vital signs and sending the alarm message to the specified target mobile phone when meet the abnormal state.In the system of this paper,it divides into front-end signal acquistion module and back-end data processing and alarm module.The front-end signal acquistion module uses by the U.S. 660-905 tripod oxygen saturation and heart rate as the detection probe, AD7314 chip temperature as the body temperature acquisition chip, sends the data to the front-end signal acquistion module,then through the wireless chip 24L01 sends to the back-end data processing and alarm module,the MSP430F149 is the core of controling in the back-end module,processing the front-end data, finally use TFT2.4 inch color screen to display the relevant values, the main controller is used to specify TC35I module send a warning message numbers. To attract the attention of nominee. In the section of back-end data processing,for the physiological data,such as the pluse which measured by the human body,oxygen saturation and body temperature,it obtains the relevant alarm threshold through looking out relevant medical information and advicing clinicians in order to making the whole detective and alarm system more scientific and comprehensive. The hardware design schematics and PCB layout have been completed in this paper,finally make a full summary of the work and prospect the scalability of the system in the future,the possible direction of develpoment is been to put forward.
