Speed simulation at the inspection of Doppler measuring systems for traffic speed enforcement

Cilj te naloge je iskanje tehničnih rešitev, v skladu z danimi zahtevami za kontrolni postopek, s katerimi lahko pridobimo in upoštevamo vse pomembne rezultate meritev, ki bi lahko vplivale na končni rezultat, pri simuliranju vrednosti hitrosti na Dopplerjevih merilnih sistemih. Predvsem bo prikazano, kako lahko z dobljenimi rezultati povečamo zaupanje meroslovnih institucij in nadzornih organov, prva tako pa tudi zaupanje obstoječih in prihodnjih uporabnikov. Za doseganje teh zastavljenih ciljev so uporabljena znanja, ki temeljijo na tehnologiji Dopplerjevih merilnih sistemov njihovo razumevanje principov delovanja in vrednosti izmerjenih rezultatov. Uporabljena so bila tudi znanja iz elektrotehnike, mehanike, Visual Basic programskega jezika, merilnih metod in meroslovne zakonodaje na tem področju. Za lažje razumevanje je naprej opisan Doplerski merilni sistem v obsegu njegove sestave in njegovega delovanja, s poudarkom na glavno komponento, Doplersko anteno. Nadalje je sistem bil uporabljen za pridobivanje rezultatov v obstoječem kontrolnem postopku, nakar je bil postopek ovrednoten. Na podlagi ugotovljenih pomanjkljivosti obstoječega postopka je bil zasnovan načrt s spektrom zahtev, za njihovo popolno odpravo ali marginalizacijo njihovega vpliva na končni rezultat. Na podlagi končnih rezultatov imamo zdaj izboljšan postopek, ki se lahko in se uporablja v postopku inšpekcijskega nadzora pri iskanju skladnosti, v mejah veljavnih meroslovnih zakonodajnih predpisov.Aim of this thesis is that finding technical solutions, according to given requirements for inspection control procedure, so we could obtain and consider all relevant measurement results that could have an impact on the final result, when simulating speed values on Doppler measuring systems. Above all, it is shown with the obtained results an increase of confidence towards metrological institutions and supervisory bodies and also confidence of existing and future customers. In order to achieve those pursued objectives, we used knowledge based on the technology of Doppler measuring systems for understanding the principle of its operation and values of measured results. We used also knowledge from electrical engineering, mechanics, Visual Basic programming language, measurement techniques and metrological legislation in this area. Initially, for easier understanding, Doppler measuring system and described in its assembly and its operation, with emphasis on its main component, the Doppler antenna. Later on system was used for obtaining results in existing inspection procedure, so procedure could went through evaluation. Based on the identified weaknesses within the existing procedure, a plan has been designed, set by requirements, for their complete elimination or to marginalize their influence on the end result. Based on the end results, we now have an improved procedure, which can and be used in a process of inspection control when seeking conformity, within limits of existing metrological legislation rules
