Mobile System of Monitoring and Training Cyclists with Smartphone

Abstract

This paper presents a system for monitoring and training of cyclists. Through the GPS receiver of a smart-phone, the distance, speed and altitude of the cyclist are calcu-lated and the data is sent on the Internet. To improve the rid-er’s physical aptitude, a prototype hardware and an application for smartphones with Android operating system were developed. The hardware contains an oximetry module and a head sensor to monitor heart rate and oxygen percen-tage, and has a MCP9803M sensor to measure the temperature around the cyclist and a PIC18F2550 microcontroller for data processing. Data is sent via Bluetooth to the smartphone and displayed on the screen. To evaluate the performance of the rider, 6 training zones can be chosen, and the Karvonen for-mula is used to calculate the maximum and minimum training range. It was thus possible to obtain a prototype hardware and a smartphone application for monitoring and training cyclists.
