The Development Of Portable Health System Basedon Outdoor Sports

With the development of economy, more and more people are joined to the outdoor sports, a large proportion of them are outdoor exploration and extreme sports enthusiasts, How to effectively safeguard security problem in the outdoor sports movement increasingly highlights its importance. In the process of outdoor sports, we need monitoring, movement environment and human health signs and in a dangerous situation. The system has a function of call for help, navigation and positioning, thus we can effectively to ensure the safety of life. Leave the oxygen, human body life activities will be affected. It is good for the goal of all People’s general health.lt is crucial for human body to obtain enough oxygen. We chose to detect oxygen saturation and pulse rate, to characterize healthy signs, The author adopts dynamic spectrum detection method and threshold method to increase stability and anti-interference ability, adopt the method of digital filter to enhance the accuracy of signal; Real-time monitor whether the campaigners falls fall cliff is vital significance to ensure safe, use accelerometer and stable cooperate with suitable algorithms can effectively real-time monitoring movement situation, and can be set automatically for help; Sports environment test is USES the monolithic integrated solutions LPS331, the24bit embedded temperature and sensor altimeter chip. Using the module can detect the movement of environment temperature, atmospheric pressure and height, and can be predicted simple climate change on the basis of it, the module can enhance navigation signal the signal strength of the whole system design considering the demand of low power consumption. For real-time monitoring module power consumption is lower than100uA. Tablets and system modules connected by bluetooth4.0communication interface, with low power consumption, stable characteristics of communication. With outdoor sports tablets using the whole system, provide the Bei dou navigation\GPS dual-mode, tablet display relevant information according to health campaigners signs and security situation, through the network publishing SOS rescue signal and locate information effectively ensure the safety.This article mainly includes the following several parts:Pulse blood oxygen monitoring module principle and the realization of the hardware and software、 theoretical derivation of fall detection module and algorithm implementation、The realization of the atmospheric pressure detection and navigation signal enhancement、 The communication module with bluetooth、Tablet bluetooth communication module、 data reception and display based on the JAVA platform.Next stage I will to complete the data fitting, bluetooth4.0communication module design and implementation of the function; Display function of the android platform and Thesis writing.
