Diplomska naloga obsega načrtovanje, izdelavo, preizkus ter analizo meritev strojnega in programskega dela brezžičnega senzorskega sistema za analizo skokov in udarcev žoge pri odbojki. Cilj diplomske naloge je razvoj sistema, ki je zmožen brezžičnega prenosa, obdelave, prikaza in shrambe podatkov pridobljenih o funkciji stopala. Te podatke se naknadno analizira, za namen pridobitve rezultatov, ki bi privedli do boljšega razumevanja funkcije stopala za namen gibanja. Ozadje diplomske naloge predstavljajo predvsem lastne izkušnje s sistemi za pridobivanje podatkov v športu in navdušenje nad senzorsko tehniko, ki športu doda nove možnosti. Motivacija za izdelavo diplomske naloge izhaja iz osebnih in tehničnih razlogov; zaradi težje poškodbe prisotne v moji odbojkarski karieri, se je povečalo moje zanimanje in navdušenje za uporabo senzorske tehnologije v športu. To me je usmerilo v razvoj sistema, ki bi lahko pomagal pri vadbi in preprečevanju poškodb v športu. Metodologija razvoja in preizkusa sistema je temeljila na združevanju izkušenj in nasvetov s strani mentorjev, lastnega preizkušanja ter sprotnega učenja. Vsak korak pri razvoju in izpopolnjevanja sistema je bil premišljen in izveden na osnovi teoretičnih znanj in praktičnih izkušenj. Rezultati so potrdili večino naših predvidevanj in pričakovanj. Rezultati podrobnejših analiz pa so raznovrstni; nekateri sovpadajo z našimi pričakovanji, drugi ne. Prvi funkcionalni preizkus sistema nam je prinesel zanimive rezultate, ki spodbudijo k nadaljnjim razvoju sistema. Pri pregledu rezultatov prvega funkcionalnega preizkusa so bile odkrite možne izboljšave izvedbe sistema in meritev. Prepričan sem, da bodo pri nadaljnjem razvoju in preizkušanju sistema pridobili nove zanimive in koristne podatke, ki bodo korist pri vadbi in v pomoč pri morebitnemu preprečevanju poškodb v odbojki.

• Title: Wireless sensor system for the acquisition and analysis of jumps and spikes in valleyball

Abstract

The bachelor thesis contains planning, production, testing and result analysis of the software and hardware aspect of a wireless system for analyzing jumps and ball impacts in volleyball. The goal of the thesis is to develop a system that would be capable of capturing, wireless transfer, processing, displaying and storing data derived from the function of the foot. This data is subsequently analyzed, for the purpose of obtaining results, which would lead to a better understanding of the function of the foot for the purpose of movement. The background of this bachelor thesis consists mainly of my own experience with systems for data acquisition in sport and my enthusiasm for sensors in sport, which adds new opportunities to sport. Motivation for the preparation of the thesis is of personal and of technical reasons; because of a serious injury in my volleyball career, my interest and enthusiasm for the use of sensor technology in sports has increased. This led me to the development of a system that could help in training and prevention of injuries in sports. The methodology of development and testing of the system was based on the combination of experience and advice from my mentors, personal testing, and ongoing learning, throughout the development process. Each step in the development and improvement of the system was thought-through and carried out on the basis of theoretical knowledge and practical experience. The results confirm most of our predictions and expectations. The results of more detailed analyzes are diverse; some confirm our expectations, others do not. The first functional test of the system has brought interesting results that encourage further development of the system. During the review of the first functional test, we got ideas about possible improvements and upgrades to the system and the measurement process. I am convinced that in the further development and testing of the system, new interesting and useful data will be acquired, which will benefit training and help with possible prevention of volleyball injuries.
