Design Of Animal Physiological Signal Detection System

The 21st century is century of life science. People will discover life arcanum from gene level. Experiments and researches on animals are important supplies to life science. With the elevation of life quality and fast development of medicine, the relationship between biomedicine and electronic appliance has been more and more close .China has been a big country in farming , to advance the farming level, we have to depend on animal biology technology, which is an very important part of biology technology and vital to the development of farming. To satisfy the demand in research clinic inspection and specialty teaching and to accelerate the popularization of biomedicine electronic appliance , it is very practical and significant to design the convenient biomedicine electronic appliance.The aim of the project is to design an animal physiological signal detection system based on USB2.0 to explore the solution of fast physiological signal detection. The thesis also establishes a firm foundation for expert detection devices in medicine use.The thesis introduce the circuit design of analog signal pretreatment, analog-to-digital convert ,data acquisition and transmission ,and explain the software design in system control, USB device driver, terminal application. The system can fulfill detect the physiological signal such as blood pressure signal.
