Energy-saving intelligent street lighting system
The SmartLighting project is the second development stage of the SmartLighting technology created at Anhalt University of Applied Sciences and is being implemented together with the city of Dessau-Roßlau. The aim is to develop, implement and optimize an energy-efficient, motion-sensitive and adaptive street lighting system.
The system is based on a large-scale wireless sensor network that intelligently networks existing street lights and only provides lighting where and when it is actually needed. The movements of pedestrians and road users are recorded, analyzed and used to dynamically control lighting zones.
In addition to significant energy savings, the system enables traffic data to be recorded and evaluated to support traffic planning and management. The developed solution increases safety in public spaces and at the same time extends the service life of the lighting infrastructure.
Scientific tasks:
- Development and analysis of a distributed control concept for adaptive street lighting
- Research into sensor data fusion and motion vector recognition for predictive lighting control
- Scientific investigation of energy-efficient lighting strategies in wireless sensor networks
- Development and analysis of communication and routing methods for static ad hoc networks
- Research into auto-configuration and localization mechanisms for distributed lighting nodes
- Analysis of traffic and movement data to optimize traffic flows and infrastructure
Test installation in Bernburg-Strenzfeld
At the end of 2017, a test installation with 19 SmartLighting systems was implemented in Bernburg-Strenzfeld along a connecting road between the Anhalt University of Applied Sciences campus and the Bernburg urban area. The system uses PIR sensors and WLAN components for demand-based lighting, particularly for bicycle traffic; two systems have a mobile internet connection.
Energy savings of over 90% were achieved by using self-sufficient luminaires with photovoltaics and battery storage. In addition, the integrated computer logic made it possible to monitor the battery status and energy generation, ensuring stable operation even in winter conditions with low solar radiation.
