Modular development telemonitoring system

This paper presents a modular development telemonitoring system. The system consists of wireless communication and biosignal acquisition modules. These modules are connected to a control unit via an extension board. The control unit is based on STM32 EVO Primer development kit. An integrated accelerometer is used for monitoring of subject´s activity. The system features a signal processing and heart rate frequency computing algorithm. A memory card is used for saving the heart rate frequency. A heart arrhythmia alarm and an activity monitor are implemented in the system as well. The system has a simple alarm and a signal visualization program for PC. The modular solution is suitable for other biosignals acquisition and for miscellaneous means of wireless data transfer. The system provides raw signal data for further signal processing. This system was designed mainly for development, research and educational purposes in telemonitoring systems.
