Abstract

U okviru ovog rada proučena su osnovna načela rada sustava za lokalno pozicioniranje. Dan je kratak pregled postojećih gotovih LPS sustava, algoritama kalibracije i lokalizacije te metoda mjerenja udaljenosti. Proučen je i u programskom paketu MATLAB implementiran MDS algoritam, koji je korišten za rješavanje problema kalibracije i lokalizacije u ostvarenom sustavu. Nadalje, razvijeno je sklopovlje i programska potpora bežičnog senzorskog čvora koji se sastoji od ultrazvučnog i radijskog primopredajnika. Implementirana je metoda za mjerenje udaljenosti preko mjerenja vremena propagacije ultrazvuka, uz upotrebu izravne sinkronizacije preko radijskih primopredajnika, te metoda za mjerenje udaljenosti preko mjerenja vremena propagacije povratnog signala. Konačno, ostvaren je 2D sustav za određivanje položaja pokretnog čvora.

Abstract (english)

In this thesis, the basic principles of local positioning systems have been described. A brief overview of existing ready-made LPS systems, calibration and localization algorithms, as well as distance measuring methods, were elaborated. The MDS algorithm was implemented in MATLAB, and it was used for solving the calibration and localization problems in this work. Furthermore, hardware and software for wireless sensor node, comprising of ultrasound and radio transceiver, have been developed. For the purpose of distance measurements, a method that uses the propagation times of ultrasound with direct synchronization through the radio transceiver, was implemented. Moreover, a method that uses the propagation time of feedback signal, was also used. Finally, the 2D system for mobile node positioning was developed and tested.
