The object of this thesis is the study, implementation and experimental verification of a temperature acquisition system to be applied to the monitoring of the driver in a vehicle. This acquisition system contributes to the monitoring of the psycho- physical state of the driver, to guarantee his safety. The design of this system was carried out by measurements on object of known temperature with both sensors, to understand their behavior, and then moving on to acquisitions directly from the steering wheel. To initialize the sensors and be able to measure with them, the Arduino microcontroller was used. After having programmed them, and having acquired the measurements on objects and the steering wheel, data were put on MatLab to graph the various trends, and to make the calculations necessary to establish their behaviour. The measurements on the object turned out to be not very accurate, partly due to the measurement conditions, partly due to the containers in which these objects were located. The steering wheel measurements, however, led to good results. Being capable of measuring the driver well both at “rest” conditions and during driving, these sensors could be effectively implemented on car steering wheels in the future.
Oggetto di questa tesi è lo studio, implementazione e verifica sperimentale di un sistema di acquisizione di temperatura da applicarsi al monitoraggio del conducente in un veicolo. Questo sistema di acquisizione concorre al monitoraggio dello stato psico- fisico del guidatore, per garantirne la sicurezza. La progettazione di questo sistema è stata realizzata acquisendo delle misure su oggetti di temperatura nota con entrambi i sensori, per capire il loro comportamento, per poi spostarsi alle acquisizioni direttamente su volante. Per inizializzare i sensori e poter eseguire delle misure, si è fatto uso della scheda a microcontrollore Arduino. Dopo aver programmato la scheda, ed aver acquisito le misure su oggetti e volante, queste sono state elaborate in MatLab per graficare i vari andamenti, e per fare i calcoli necessari a stabilire il loro comportamento. Le misurazioni sugli oggetti si sono rivelate non molto accurate, in parte per via delle condizioni di misurazione, in parte per i contenitori in cui questi oggetti si trovavano. Le misurazioni da volante hanno invece portato a buoni risultati. Essendo capaci di misurare adeguatamente le condizioni del guidatore sia a “riposo” che alla guida, tali sensori potranno essere, in futuro, efficacemente implementati sui volanti delle auto.

Abstract
The object of this thesis is the study, implementation and experimental verification of a temperature acquisition system to be applied to the monitoring of the driver in a vehicle. This acquisition system contributes to the monitoring of the psycho- physical state of the driver, to guarantee his safety. The design of this system was carried out by measurements on object of known temperature with both sensors, to understand their behavior, and then moving on to acquisitions directly from the steering wheel. To initialize the sensors and be able to measure with them, the Arduino microcontroller was used. After having programmed them, and having acquired the measurements on objects and the steering wheel, data were put on MatLab to graph the various trends, and to make the calculations necessary to establish their behaviour. The measurements on the object turned out to be not very accurate, partly due to the measurement conditions, partly due to the containers in which these objects were located. The steering wheel measurements, however, led to good results. Being capable of measuring the driver well both at “rest” conditions and during driving, these sensors could be effectively implemented on car steering wheels in the future.File | Dimensione | Formato | |
