Development Of A Wireless Multiple Physiological Parameters Monitoring System For Athletes

In recent years, the physiological and biochemical parameter applied in athlete's training and competition has become a hot research topic at home and abroad. Whether coaches or researchers wish to quantify the physiological and biochemical parameter for the purpose of researching on the exercise load, fatigue and recovery problem in the training of athletes. In order to guide athlete's training and competition , enhance sports performance and reduce injuries . There is lack of pertinency for athletes, single function or inconvenience to carry in traditional exercise detecting equipment(such as treadmill exercise equipment, medical monitor istrument, isokinetic device, isokinetic exercise devices, senior exercise training state monitoring system, etc.).Therefore, the development of a wireless multi-parameter wireless monitoring system for athletes, by the request of achieving a portable, real-time accurate monitoring system during training is necessary for the detection of the foremost changes in physiological parameters and exercise disease prevention simultaneously.The project based on modern electronic technology, embedded systems, wireless communication technology, medical knowledge, combined with sophisticated medical detecting technology, athlete's dynamic characteristics and physiological characteristics, making up for the defect of traditional exercise equipment. Meanwhile setting up a new theoretical concept instead of tranditional fixed concept of regarding athletes as patient, will meet the demands for modern training monitoring equipment of the competitive sports and massive physical training with good market prospects.The project mainly researches on physiological parameters collected by physiological sensor(such as ECG electrode, Oxygen saturation probe, etc)and sent to data process system via Wireless transceiver modules for processing , displaying and analyzing data.The work done in the design as followed: 1) According to athlete's exercise and physical characteristics, it establish the corresponding overall implementation program, including data collection programs,wireless transceiver program, data processing program.2) According to wireless monitoring terminals long time required by the athletes to wear, it select high-speed, low power consumption control chip, as well as other low power consumption of the SMD chip in order to reduce power consumption, reduce size and weight, while selecting comfortable, solid appearance and wearing ways.3) Choosing high sensitivity and anti-interference physiological sensors; designing sensors fixed way fit with the body exercise status.4) Designing other subsystem based on the overall circuit: signal acquisition circuit, A/D conversion circuit, filter circuit, the signal storage circuit, data wireless transceiver circuit;Drawing printed circuit board (PCB).5) compiling software systems: software for the computer and software for the monitoring terminals.6) Debugging the modules and system, it solve the problem of debugging process in order to adjust and optimize system.
