Styrsystem och förenklad tidssynkronisering för heterogena IoT-nätverk med måttliga tidskrav (Swedish)
Abstract [en]

The company QTPIE conducts research on drivers and their unconscious reactions when driving. To help, they use smart devices that today must be individually handled at the start and end of a run, and have individually set timestamps, which can lead to differences between the units when data is entered and collation of the units' data after a run.  

The purpose of this study is an integrated control system in the form of an Android mobile application that partly facilitates the start and end of a run, and partly synchronizes time stamps between all devices. The intention is to build a heterogeneous mobile network with a central control unit and implement time synchronization and investigate whether the heterogeneity affects the implementation of the network.  

The result was an Android mobile application that controlled selected external smart devices, synchronized these, and had time synchronization built in at the start of each run. 

Abstract [sv]

Företaget QTPIE gör undersökningar på förare och deras omedvetna reaktioner vid körning. Till hjälp använder de smarta enheter som idag måste hanteras individuellt vid start och slut av en körning, samt har individuellt satta tidsstämplar, vilket kan leda till differenser mellan enheterna vid datainmatning och sammanstrålning av enheternas data efter en körning. 

Avsikten med den här studien är ett integrerat styrsystem i form av en Android mobilapplikation som dels underlättar vid start och slut av en körning, dels synkroniserar tidsstämplar mellan alla enheter. Avsikten är att bygga upp ett heterogent mobilt nätverk med en central kontrollenhet samt implementera tidssynkronisering och undersöka om heterogeniteten påverkar implementeringen av nätverket.  

Resultatet blev en Android mobilapplikation som styrde valda externa smarta enheter, synkroniserade dessa samt hade tidssynkronisering inbyggt vid start av varje körning.
