Heart is one of the important organs of human body
cardiac function directly determines human body’s blood
oxygen supply
and therefore it becomes the most worthy of research in sports medicine. Heart rate is an important basis for determining intensity of exercise in athletic sports and rehabilitation. Heart rate sensor is the key component for accurate acquisition of heart rate signal. Aiming at problem of short transmission distance of wireless signal of analog and digital two kinds of heart rate sensor
combined with actual needs of athletic sports
focusing on working principle of wireless relay device of digital heart rate sensor
design a wireless relay device for Polar digital heart rate sensor
which provides a hardware platform for real-time processing of remote wireless heart rate.
