Design and implementation of Traffic Flow based Street Light Control System with effective utilization of solar energy

Abstract

Street Light Control System which operates automatically is not only easiest but also the intelligent system. This system can be set to operate in automatic mode, which regulates the streetlight according to detection of moving object. The main objective of this project is to save the power from street lighting in rural areas where there will be very less use of street lights after 11pm to morning 5am. So here, in this project we use automatic ON/OFF mechanism of street lighting by detecting the movement of object (vehicle/person).

In this project, we use renewable source of energy i.e., solar power for street lighting. Apart from this, we replace normal bulbs in street lighting with LEDs due to which the power consumption in reduced by 3 times. And also, we use IR sensors to detect the movement of object to activate the lighting a few meters before the object is about to reach the lighting area.

Here, the IR sensors are deactivated after a timing delay of 30seconds and similarly remaining sensors are activated and deactivated after 30seconds. We also place a battery backup for 2days in order to supply power continuously in the worst cases such as rainy time. We also connect this solar power region to the grid to supply excessive power to the grid to avoid saturation of battery and also vice-versa i.e., to receive power from grid in rainy seasons and winter seasons. So, this is a very effective way of saving a large amount of power.
