20.500.12556/RUL-160921 Ovrednotenje senzorjev merilnega sistema za psihofiziološko merjenje temperature Evaluation of measuring system sensors for psychophysiological temperature measurement Diplomsko delo je osredotočeno na primerjavo dveh različnih senzorjev, TSD202A in TSD202D, ki imata različni toplotni masi in konstrukciji. Glavni cilj raziskave je ugotoviti, kateri izmed teh dveh senzorjev je bolj smiseln za uporabo v določenih situacijah, glede na njegove lastnosti in dinamiko merjenja. Metoda dela je vključevala merjenje temperature na konici prstov z uporabo obeh senzorjev. Oba smo namestili hkrati na isto blazinico prsta udeleženca, čim bližje drug drugemu, da smo zagotovili enake pogoje merjenja. Po namestitvi senzorjev smo počakali, da se temperatura stabilizira. Ko je bila temperatura stabilna, smo sprožili dražljaj, ki je prestrašil udeleženca in sprožil vazokonstrikcijo njegovega krvožilnega sistema, kar se je odražalo v padcu temperature. Nato smo spremljali temperaturo, dokler se ni ponovno dvignila in stabilizirala, ko se je udeleženec umiril. Senzor TSD202A z manjšo toplotno maso je imel krajši odzivni čas, ki je znašal 258 sekund, medtem ko je imel senzor TSD202D daljši odzivni čas, in sicer 337 sekund. Maksimalni padec temperature pri senzorju TSD202A je bil 0,661 °C, medtem ko je pri senzorju TSD202D znašal 0,524 °C. Senzor TSD202A je bil veliko bolj občutljiv na različne dejavnike, kot so vpliv sile pri nameščanju ali premik telesa, kar se je odražalo v značilni žagasti obliki grafa. The thesis focuses on the comparison of two different sensors, the TSD202A and TSD202D, which have different thermal masses and designs. The main objective of the analysis of the study is to determine which of these two sensors is more viable for use in certain situations, depending on its properties and measurement dynamics. Method The method of work involved measuring the temperature at the fingertip using both sensors. Both sensors were placed simultaneously on the same finger pad of the participant, closer to the each other to ensure identical measurement conditions. After installing the sensors we waited for the temperature to stabilise. Once the temperature was stable, we triggered a stimulus that startled the participant and triggered vasoconstriction of his circulatory system, which resulted in a drop in temperature. The temperature was then monitored until the rose again and stabilised when the participant calmed down. The TSD202A sensor with with a lower thermal mass had a shorter response time of 258 seconds, while the response time of the while the TSD202D sensor had a longer response time of 337 seconds. The maximum temperature drop for the TSD202A sensor was 0.661 °C, while the TSD202D sensor had a drop of 0,524 °C. The TSD202A sensor was much more sensitive to various factors, such as the influence of force when positioning or the displacement of the body, which is reflected in the graph's characteristic shape. elektrotehnika meritve stres termistorski temperaturni pretvorniki senzorji TSD202A TSD202D BIOPAC MP100 SKT100C odzivni čas maksimalno znižanje temperature občutljivost. electrical engineering measurements stress thermistor temperature transducers sensors TSD202A TSD202D BIOPAC MP100 SKT100C response time maximum temperature reduction sensitivity. true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-09-05 13:20:04 2024-09-05 13:20:08 2025-08-08 13:33:32 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 61143 206520067 Gorisek_Gasper_-_Ovrednotenje_senzorjev_merilnega_sistema_za_psihofiziolosko_merjenje_temperatur.pdf Gorisek_Gasper_-_Ovrednotenje_senzorjev_merilnega_sistema_za_psihofiziolosko_merjenje_temperatur.pdf 1 8919B1C3ACFB2126548C47F6A29CB4FD 89dbacf2d968b249c2b6427abeff1226adbc2d958e2c9f503628e3d7aa5b74c3 cd226521-6b78-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189745 Fakulteta za elektrotehniko 0 0 0
