Power consumption reduction in a remote controlled street lighting system

In this paper a remote control equipment for monitoring and managing a street lighting system is presented. It is composed by a local control, realized by master boards located inside electrical panels and slave boards mounted on each lamppost, and by a remote control realized by a central unit for the remote communication with the local control system. The communication between master and slave boards is realized using power line modems, while the remote control central unit is connected to master boards via a GPRS-GSM communication. Master board allows to choice the electrical phase for the power line communication and to send the control commands to the slave boards on each lamppost. Slave boards allow to turn on/off the lamppost, to reduce power consumption using a device developed by ALBATROS Italia S.r.L., and to detect the lamp status, checking the current flow on the lamp itself.
