Chapter 3.

Concept

This chapter covers basic concepts and ideas about the integration of Home Automation (HA)

components in Intelligent Environments (IE). It aims to give an insight into the decisions made

to improve general understanding and prepare the reader for chapter 4 on page 36.

3.1. Basic structure

Modern environments are often equipped with diﬀerent technologies. The autonomous and intelli-

gent processing of tasks in these environments is a challenging task, as pre-existing HA technologies

cannot be integrated directly. Therefore, we ﬁrst need to establish a standardized communication

basis, enabling IE to understand and interact with HA components. Figure 3.1 illustrates the basic

structure of the communication chain.

Many IE are computer-based, which can take over compute-intensive tasks, such as connecting

the individual participants as well as deriving higher reactions. Since the IE at the research group

is computer based as well, the ﬁrst step is to connect HA devices to a computer. This is done

via HA-PC gateway, as mentioned in section 2.3. The next step is software that prepares and

processes the data and ﬁnally enables the interfaces to connect to an IE. These diﬀerent parts are

elaborated in the following sections.

Another approach to illustrate the basic structure is depicted in Figure 3.2. It shows the commu-

nication chain as a set of diﬀerent layers, which gradually abstract the information. Each layer

forms a consistent module, providing a speciﬁc function to abstract information for the next layer.
