Diseño e implementación de un sistema electrónico para conducción segura, basado en monitorización de señales biométricas, utilizando tecnologías GSM, GPRS.

Abstract

An electronic system has been developed base on the monitoring of biometric signals for safe driving using GSM/GPRS technologies. The measured biometric signs were the concentration of alcohol in the blood by breath test and heart rate. The system had two physical nodes and a web application for monitoring, the information detected by sensors and other devices was processed with a free hardware platform (Arduino) at Node 1 if the alcohol sensor detects a level higher than 0,3 g/l the ignition of the car cannot be executed and a text message is sent, in Node 2 the heart rate was measured, this data was sent wirelessly to Node 1, if the heart rate is abnormal, an alert is triggered and a text message similar to the alcohol test failure is sent. The wireless communication between Nodes 1 and Node 2 was carried out by means of Bluetooth technology every minute, the transmission of data to the internet every 3 minutes using GSM/GPRS network infrastructure. In the web application a map was show indicating the location of the driver in real time if the alcohol test failed, there was an informative table that presents the calculated data and alert level trough color indicators, another information table for the monitoring of the heart rate of the same characteristics. It was concluded that monitoring biometric signals helps to ensure the safety of the driver. In this work we have measured two biometrics signs of breath and heart rate, it is important that the system has further developments with the inclusion of new biometric sensors taking advantage of the high scalability of the system.
