Smart SSL: Application of IoT/CPS design platforms in LED-based street-lighting luminaires

摘要

Smart systems - according to a simplistic definition - provide new qualities and new functionalities through the integration of formerly distinct functions, components and networks. Street-lighting (as other lighting applications) recently went already through a drastic change offered by “LEDification”. The easy electronic controllability of LEDs as light sources triggered a new change of paradigm: integration of LED based luminaires into smart systems. Smart integration necessitates among others both adaptability to the environmental conditions and intelligent remote control that require a communications systems based on a multi-layer data transfer protocol. We are reporting about an ongoing project that targets a “future proof” solution which is not restricted to lighting control but allows public lighting installations to play key roles in other smart city functions needed in outdoor public spaces such as communications with vehicles. The result of the development is a new IoT device which can be installed in street-lighting luminaires and allows physical layer (e.g. PLC, WiFi, ZigBee or other RF transmission) independent data transfer. The main functionality of the application layer of the protocol remains of course lighting control which is best implemented on the basis of existing standards (such as DALI), but the system allows the implementation of other communications tasks based on other application layer protocols.
