Chytrý bezpečnostní pás pro detekci dechové křivky

Abstract

The main motive of this bachelor thesis was to create a functional module for measuring the breathing curve using an accelerometer after a car crash, which will be attached to a seat belt. When the seat belt is activated, the module will switch from sleep mode to measurement mode. The accelerometer data will then be sent to an external device via Bluetooth low energy where it will be logged. The module is made to be safe for the user, to hold firmly on the belt, to be self-sufficient and reliable. The matlab program was used to display and evaluate the data where filtering and peak detection was performed. The control was performed using a chest measuring belt from ADInstruments, which was also used as a reference during calibration. The measured data were subjected to static analysis to verify the functionality and reliability of the measurements.
