DC Grids for Smart LED-Based Lighting: The EDISON Solution

This paper highlights the benefits and possible drawbacks of a DC-based lighting infrastructure for powering Light Emitting Diode (LED)-lamps. It also evaluates the efforts needed for integrating the so called smart lighting and other sensor/actuator based control systems, and compares existing and emerging solutions. It reviews and discusses published work in this field with special focus on the intelligent DC-based infrastructure named EDISON that is primarily dedicated to lighting, but is applicable to building automation in general. The EDISON “PowerLAN” consists of a DC-based infrastructure that offers telecommunication abilities and can be applied to lighting retrofitting scenarios for buildings. Its infrastructure allows simple and efficient powering of DC-oriented devices like LED lamps, sensors and microcontrollers, while offering a wired communication channel. This paper motivates the design choices for organizing DC lighting grids and their associated communication possibilities. It also shows how the EDISON based smart lighting solution is evolving today to include new communication technologies and to further integrate other parts of building management solutions through the OneM2M (Machine to Machine) service bus

SafeTRIP: A Bi-directional Communication System Operating in S-band for Road Safety and Incident Prevention

SafeTRIP is a project in progress partially financed by the Seventh Framework Programme's (FP7) European research and development activities in the subtheme of Sustainable Surface Transportation. SafeTRIP intends to implement a demonstrator of an integrated system, from data collection to service provision, that aims at optimising the use of road transport infrastructures. In this paper a general overview of the SafeTRIP architecture is presented. A detailed analysis and description of the functionalities characterizing the main elements of the system and a brief description of infomobility services such as alerting, disaster recovery and dynamic traffic data is given. A relevant part of this architecture is the Satellite Communication System which operates through the W2A Geostationary Satellite. To have an idea of the potentialities of the proposed system, a summary of functional requirements and performances relating to different types of services implemented is reported
