Smart Home Automation Using Controller Area Network

摘要

In several works, researches have recently proposed the use of a CAN bus (Controller Area Network) as a control network for smart home automation. The use of CAN for the lower network layers has advantages in the field of automation compared with networks based on RS485 due to its multimaster architecture. While compared with other common bus networks such as Ethernet or networks based on token passing, CAN has real time features and ease of implementation and programming of the nodes and therefore, a lower cost. This paper presents the study and evaluation of automation and remote control of an alarm system and HVAC system (Heating, Ventilation, and Air Conditioning) of a home, using CAN as a backbone network. The first version of TUCAN (Tuple Space and CAN) has been also used for the software of the nodes. TUCAN is a data-centric lightweight middleware that provides a CAN bus abstraction, and is based on the concept of Tuple Channel Space. A prototype with four nodes has been used to study the feasibility of the CAN bus as a single network and to evaluate TUCAN middleware.
