Smart Street Lighting Control System Design Based on PLCC

Conventional street lighting systems in areas with a low frequency of passersby are on in the night without purpose. The consequence of this is that a large amount of power will be wasted. With the broad availability of modern technology like light-emitting diode lamps and everywhere available wireless internet connection, fast reacting, reliably operating, and power-conserving street lighting systems can be realized. The purpose of this work is to describe the Intelligent Street Lighting (ISL) system, a first approach to accomplish the demand for flexible public lighting systems. Monitoring of street lights and controlling is very much important in developing country to reduce the power consumption hence this paper presents a street light control system which combines various technologies like a photosensitive detector (LDR), infrared photoelectric control, Light Emitting Diodes (LED), power transistors, dual relays with transmission of controlling commands over existing power lines. This system contains power line carrier channel to detect the day and night conditions to turn lamps on, merely during night time. This system also includes fault detection and feedback circuit to indicate the present state of the control system. The intact information regarding these various aspects is transferred to nearby control terminal (base station) by power line carrier communication to visualize the state of the system by creation of Graphical User Interface (GUI) there. It allows substantial energy savings with increased performance and maintainability.
