A wireless networked LED street lighting system based on IOT with centralized and remote control technology has emerged as an innovative smart city application with great potential to reduce energy cost and enhance public safety.
Street lighting has always been a major concern in energy efficiency because it represents 10% to 20% of the electricity used in most countries—sometimes more in developing countries. Street lighting faces many problems. Some of these are:
- Street lights left on during the day, lead to a wastage of electricity.
- Inadequate/poor fault managing mechanism, leads to a delayed repair of the faulty lights.
- Non-uniform light intensity levels, lead to energy waste.
- No mechanism to check the power theft and leak from the lines meant for the street lighting supply, leading to revenue loss
Switching to LEDs is not enough to save the energy that is wasted in the listed above methods. To use the street lighting in an energy efficient manner, a smart intelligent wireless sensor network of Internet of Things (IoT) enabled device has to be installed to monitor and control the light system and to send the real-time data along with the location to the secured cloud.
This system integrated within a campus microgrid demonstrates the benefits for smart city applications for public safety enhancement.provide real-time monitoring and control of street lights in lighting networks both A full suite of control features include remote on/off, dimming, scheduling, daylight harvesting, emergency management and smart grid demand / response energy management. Enhanced fault monitoring and management are standard features allowing retrieve real-time power consumption data and lamp light levels from a central server accessible via a secure web connection. Lamp controller consists of advance microcontroller base systems with analog inputs and RF communication systems. The communication systems are designed on advance wire less mesh network technology. .
