Abstract

Dandanes ljudje vedno večji del dnevnih migracij opravimo zgodaj zjutraj oziroma pozno zvečer – torej v tistih delih dneva, ko primanjkuje naravne svetlobe, zato takrat za varno udeležbo v cestnem prometu potrebujemo dobro cestno razsvetljavo. Z namenom, da bi ugotovili, kako dobro so osvetljene cestne površine, smo v okviru diplomskega dela zasnovali in izdelali napravo, imenovano zapisovalnik osvetljenosti zunanjih površin. Zapsiovalnik s pomočjo senzorja osvetljenosti LP PHOT 03 BL AC in GPS modula SIM808 EVB-V3.2 v časovnih intervalih zajema podatke o osvetljenosti in trenutni lokaciji ter jih zapisuje v tekstovno datoteko. Po končanem zapisovanju podatkov naprava na podlagi izmerjenih rezultatov izriše zemljevid, na katerem je z barvo prikazana osvetljenost cestnih površin na posameznih lokacijah. Svetlejša barva na zemljevidu predstavlja bolj, temnejša pa manj osvetljeno površino. Narejeno napravo smo preizkusili v zahodnem delu Ljubljane in njeni okolici. Z analizo dobljenih rezultatov smo ugotovili, da lahko s pomočjo zemljevida, ki ga izriše naprava, opazimo razliko med starimi in novimi cestnimi svetilkami ter da je večina cest in prehodov za pešce osvetljena skladno s priporočili, ki jih je določilo Slovensko društvo za razsvetljavo.

Secondary title: Development of an illuminance and position data logger
Secondary abstract: Nowadays, people make more and more of their daily migrations early in the morning or late in the evening - that is, when there is a lack of natural light. To increase safety in those parts of the day we need good road lighting and to determine how well-lit road surfaces are, as part of our thesis, we designed and manufactured a device called an illuminance and position data logger. With the help of LP PHOT 03 BL AC illuminance sensor and SIM808 EVB-V3.2 GPS module, the data logger captures data on illuminance along with the current location and writes them to a text file. After recording the data, the device draws a map based on the measured results. On the map, the illumination of the road surfaces at individual locations is shown in color. A lighter color on the map represents more and a darker, less illuminated surface. We tested the device in the western part of Ljubljana and its surroundings. By analyzing the obtained results, we found that with the help of the map drawn by the device, we can see the difference between old and new road lamps and that most roads and pedestrian crossings are adequately lit in accordance with the recommendations set by the Slovenian Lighting Association.
