| which allows both autonomous and on-demand control. Minimum energy consumption is achieved by regulating the street lights depending on illumination level and motion detection. The system has been tested in a real infrastructure at a University Campus. Every street light has been equipped with a wireless communication device which integrates a luminosity sensor, in order to maintain only the necessary light level, and a set of motion sensors, in order to increase the level just when there are pedestrians and vehicles around. Devices communicate through an IEEE802.15.4 interface and 6LoWPAN as network protocol, enabling external monitoring/control and between street lights interaction. When autonomously working, a state machine within the Contiki OS decides the most suitable dimming level according to sensor values and other programmable parameters such as illumination thresholds or neighbor configuration. On the other hand, since the system can be controlled remotely, luminosity levels, calibration and behavior parameters can be manually adjusted. Besides, the motion sensors may also be used during daylight to monitor citizen flow, offering additional features as people behavior patterns recognition and security assistance. | |
