Intelligent Monitoring and Control Rendered to Street Lighting

Intelligent Monitoring and Control Rendered to Street Lighting is a novel idea to wirelessly control street lights. Every individual streetlight i.e. node has a unique IPv6 and IEEE address through which it can be controlled from the control centre. The system is designed using a microcontroller MSP430F6636 and an RF IC CC1180. The RF IC is used for sending and receiving the monitoring and control signals to and from the control centre. The microcontroller processes the signals obtained from the RF IC as well as the lamp. Messages are sent from control centre to nodes via gateway, which is a node with a GPRS module. The gateway passes the messages to the respective nodes by hopping the message between the nodes. The communication between nodes takes place in ISM band and that between gateway and control centre through GPRS. Automatic as well as manual remote switching on or off of individual lamps, controlling their light intensity and acquisition of status and failure is possible. Through this system we can save almost 50% of the power consumed just by strategically dimming lights. Maintenance and patrol costs are also reduced. This paper attempts to make this system as flexible, compact and cost effective as possible, also the front end can be modified to suit any application.
