This paper presents user-centric energy efficient lighting control architecture for street lamps. The system utilizes ZigBee technology to implement wireless mesh network of street lamps. The coordinator, serving as gateway between ZigBee nodes and internet, relays information of interests to remote user. The proposed system comprises of LED lamps, gateway node, and management software that offer remote monitoring and control of the lamps. Each LED lamp is integrated with ZigBee node, sensors and the Controller module along with ballast actuator. To realize effectiveness of proposed system, prototype has been installed inside University.
Conventional lighting systems work on bi-level approach, either on or off. When on, operates on rated power and there is no control to adjust power consumption by any means. Lighting control systems are introduced to reduce energy consumption inherent to conventional lighting systems. These control systems can be part of building automation system to cover indoor lighting or can be controlled through regional office of metropolitan area if needs to control outdoor lighting of large urban area, such as, street lights.
Street lights are controlled either individually or in group. In group based control, several lights are jointly connected to mains, decreasing wiring cost. Group based control system is simple in its functionality but disconnects all street lights within group due to maintenance and troubleshooting. However, in individual control, lamps are independently connected to mains at the expense of additional wiring and labor costs. Numerous lighting control systems have been proposed to reduce energy consumption, using occupancy sensing approach, and light level tuning. Controlling of traditional lighting system mainly depends on effectiveness of adopted technology. Two major technologies, PLC and Wireless Sensor Network, have gained much attention for lighting control applications. Despite reducing wiring structure in PLC based designs presented in occasional drops may occur in PLC networks operating on LV (Low Voltage) power lines. These drops are caused by noise and attenuation, and can last from a few minutes to few tens of minutes. Due to carrier signal attenuation, there may be high latency or communication failure in PLC based design. On the contrary, deploying communication infrastructure based on WSN, such as ZigBee, eliminates wiring overheads.
The proposed system is designed to reduce energy consumption of outdoor premises and demonstrated by developing prototype to control street lamps. The system minimizes energy consumption for the benefit of user and environment concurrently. Besides, the system may be integrated with to assist in traffic management. Based on preliminary results, partially installed user-centric lighting system can be expanded across the university campus due to reliability and robustness offered by proposed system. Besides, proposed design may also be optimized by providing sensor’s feedback to the Controller.
Hello….. This is the post your code column…… The one who implements the project can post their code here. So that the same code will be shared to every one who is having the same perspective…..
