Abstract [sv]

Målet med detta examensarbete är att utreda de möjligheter som erbjuds

vid introduktion av närvarodetektion och ett kommunikativt nätverk

för vanliga vägguttag. Detta har undersökts med införandet av ett

trådlöst nätverk med Smartphone styrning.

En förundersökning har genomförts undersökandes de eventuella

besparingar som kan göras genom att reducera standby-förluster i

hushåll. Undersökningen ledde till slutsatsen att standby-energi står för

en onödigt hög del av den totala energiförbrukningen i moderna

hushåll.

En prototyp med syftet att utvärdera genomförbarheten och nyttan av

närvarodetekterande, styrbara och nätverkade strömuttag har designats

och konstruerats. För kontroll av nätverket har även en mjukvaruprototyp

för Smartphones tagits fram i programspråket Symbian C++. Informationsnätverket

är baserat på Bluetooth-teknologi.

Funktionaliteten hos den färdiga prototypen visar att det förslagna

konceptet som sådant är fullt genomförbart men att blåtandstekniken

har vissa begränsningar som måste arbetas runt för att få tillfredställande

prestanda inom nätverket.

Abstract [en]

The aim of this master thesis has been to investigate the possibilities

made available with the introduction of user awareness and network

capabilities to an ordinary wall socket. This is done by the usage of

wireless network construction and Smartphones for control of said

network.

A preliminary investigation was performed regarding the possible gains

of reducing standby power consumption in households. The investigation

concluded that standby power consumption stands for an unnecessary

high part of the total energy consumption of a modern household.

A prototype with the purpose of evaluating the feasibility and use of

user aware, controllable and networked power sockets has been designed

and constructed. An application using Symbian C++ deployed on

a Smartphone has been developed for control and configuration of the

network.

The information network is based on Bluetooth technology.

The functionality of the finished prototype shows that the proposed

concept is fully realizable but that the Bluetooth technology has some

inherent limits that need to be worked around in order to achieve

satisfying network performance.
