Abstract
V industriji bele tehnike so podjetja v panogi vse bolj usmerjena v digitalizacijo njihovih produktov ter sočasno racionalizacijo proizvodnih procesov. V smeri stroškovne optimizacije se funkcije več ločenih zaznaval tako združuje v eno samo t. i. multifunkcijsko zaznavalo. Tovrstna zaznavala omogočajo implementacijo naprednih premijskih funkcij tudi v aparate srednjega in nižjega cenovnega razreda. V sklopu magistrske naloge je izvedena analiza delovanja multifunkcijskega zaznavala, ki omogoča sočasen zajem pospeškov, tlaka, temperature ter RGB barvnega spektra. Za zaznavanje razbarvanosti perila je uporabljen RGB senzor, njegove vrednosti pa transformiramo v CIEXYZ in CIELAB barvni prostor. Ugotovljeno je, da je možno zaznati razbarvanje rdečega perila ob prisotnosti umazanega perila (umazanije) ter da so s transformacijo vrednosti RGB senzorja v CIELAB barvni prostor razlike še bolj očitne.

Title:Performance analysis of a multifunction sensor in domestic appliances
Abstract:
In the domestic appliances industry, companies are increasingly focused on digitalizing their own products and simultaniously racionalizing their manufacturing processes. In the wake of cost optimizations, functions of multiple seperate sensors are merged into a singular multifunction sensor unit. This sensor units enable the implementation of otherwise premium functionalities into the appliances of middle and lower price ranges. In the scope of this master thesis, a performance analysis of a multifunction sensor unit, that is able to detect acceleration, pressure, temperature and RGB colour spectre, was made. The RGB sensor was used for detecting the decolourization of wash laundry, while the sensor values were transformed into CIEXYZ and CIELAB colour space. Our findings indicate, that it is possible to detect the red colour decolorization in spite of the presence of stains, while the transformation of RGB sensor values to a CIELAB colour space elevates the differences in the results to become more pronounced.

Keywords:RGB sensors, washing machines, colour detection, red colour, testing, colour space CIEXYZ, colour space CIELAB
