Abstract:Napredek tehnologije je povzročil širjenje lokacijskih tehnologij dostopnih širšemu krogu ljudi. GPS (globalni sistem pozicioniranja) je bil včasih dostopen le za vojsko in njene namene, v današnjem življenju pa je navigacija predvsem v prometu široko uporabna in razširjena. Najprej se je GPS pojavil kot navigacijska naprava, ki so jo namestili na vetrobransko steklo v avtu. Dandanes pa so GPS sprejemniki že vgrajeni v avte, pametne telefone in ure. Vendar pa navigacija z GPS deluje samo v odprtem prostoru, saj GPS signal ni dosegljiv v zaprtih prostorih, ker mu stene, pohištvo, streha,... predstavljajo oviro. Ker je navigacija v odprtem prostoru dobro uveljavljena in delujoča, v zaprtem prostoru pa še ne, je cilj tega projekta raziskati področje lokalizacije tarče ali vozlišča znotraj zaprtega prostora. Problem je bil, kako določiti lokacijo premičnega vozlišča. Za rešitev problema smo uporabili 3 stacionarna vozlišča, ki so vzpostavila komunikacijo s premičnim vozliščem in na podlagi časa preleta elektromagnetnega valovanja izračunala razdaljo med stacionarnimi vozlišči in premičnim vozliščem. Nato smo te razdalje preko enega izmed stacionarnih vozlišč (preko USB kabla priključeno na računalnik), s pomočjo serijske komunikacije poslali v naš Visual Studio program na računalniku. S pomočjo metode trilateracije smo izračunali koordinate premičnega vozlišča, jih zapisali v SQL tabelo ter s pomočjo spletne strani prikazali zadnjih 5 podatkov o lokaciji premičnega vozlišča na internetu.
Keywords:Spletna stran, lociranje v prostoru, premično vozlišče.

Title:Localization or detection of object of indoor place
Abstract:The advancement in technology has led to the spread of location-based technologies accessible to the masses. The Global Positioning System (GPS) was at the beginning accessible only to the military and its intentions, but nowadays navigation is widespread and most often used in vehicles. At first, the GPS appeared as a navigational device, which was placed on a cars windshield. Nowadays, GPS receivers are factory installed in cars, smartphones and even watches. However, GPS navigation only works outdoors, the GPS signal is not available indoors, because the physical barriers like walls, roofs, furniture … obstruct the signal. Navigation in open space areas is well-established and functional, but the same can’t be said for locating an object indoors, so this project was done to research the field of target or node locating indoors. The problem was how to determine the location of the moving node. To solve the problem, we used 3 stationary nodes that established a communication with the moving node and calculated the distance between the stationary nodes and the moving node based on the flight time of electromagnetic waves. Then we sent those distances through one of the stationary nodes (connected with a USB cable to the computer) with help of serial communication to our Visual Studio program on the computer. Using the trilateration method, we calculated the coordinates of the moving node, stored them in the SQL table, and displayed the last 5 locations of the moving node from the table on a web page.
Keywords:Website, location in indoor place, mobile node.
