[eng] Nowadays the automation of a building is implemented in the formof a Distributed
Embedded System (DES), that is, as a set of nodes interconnected bymeans of a communication
network that cooperate to achieve some objective. In this context the
objective is to monitor and control the physical processes of the building. Moreover,
these processes typically have specific operational requirements like, for instance, realtime
requirements. That is why DESs are usually implemented as closed systems using
specialized technologies.
In recent years, the concept of Internet of Things (IoT) has grown in popularity.
Basically, it consists in creating a connection between a thing and the Internet, where
this thing can be any physical device susceptible of being monitored and/or controlled.
Obviously, there is a huge intersection among the concept of a DES and IoT. Actually, it
would be interesting to merge them in order to get the main advantages of each one.
In this project we will describe the development of a distributed embedded system
that executes various tasks demanding specific real-time communication requirements.
More specifically, the system will execute two tasks; a domotics task and a control task.
Also, the integration of an IoT platforminto this system will be implemented in order
to create new possibilities and applications.
The Hard Real-Time Ethernet Switching HaRTES is used as the communication
network of the DES. This network makes it possible for the nodes of the DES to exchange
real-time and non-real-time traffic. Additionally, Sentilo will be used as the IoT
platform. This solution makes it possible for applications to interact with the sensors
and actuators in an easymanner.
Finally, the creation of a user interface will be carried out to reflect the applications
that the IoT platformoffers. It will provide the user a way to monitor and control the
system without having to be directly connected to it.
