Intelligent Street Lighting System Using GSM (Electronics/Computer Project)

ABSTRACT:

Conventional street lighting systems in areas with a low frequency of passersby are online most of the night without purpose. The consequence is that a large amount of power is wasted meaninglessly.

With the broad availability of flexible-lighting technology like light-emitting diode lamps and everywhere available wireless internet connection, fast reacting, reliably operating, and power-conserving street lighting systems become reality.

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.

METHODOLOGY

Firstly, Chips would be made to be installed on the lights. These chips will consist of a micro-controller along with various sensors like CO2 sensor, fog sensor, light intensity sensor, noise sensor and GSM modules for wireless data transmission and reception between concentrator and PC.

The data from the chips would be received on a remote concentrator (PC) and the PC would also transmit the controlling action to  the chip. According to the survey of variation in the intensity of light in the field area, efficient programming would be done to ensure minimum consumption of energy.

Research:

To do a complete field study of a particular location for the existing consumption of energy, emission levels, cost of set up & maintenance, etc. of that location and design an energy efficient system.

Software (on PC):

  • To collect the data (current, power consumption, theft, carbon emissions, etc.).
  • To monitor lighting control status.
  • To command the controllers depending upon the light intensity required.

Lamp Controller:

  • Power on/off/dim the lamp.
  • Monitor the status of the lamp.
  • To collect the data from various sensors.

Communication Link:

To establish an effective communication link between the controller and PC for bidirectional data transfer.

An Intelligent Driver For Light Emitting Diode Street Lighting:

Due to light emitting diode (LED) with better performances , the demand for developing LED Street Lighting is growing continuously. Nowadays, a topic of interest in this context is the search for electronic driver in order to take advantage of LED performances. This work focuses in saving potential pitfalls during intelligent driver  design  procedure.

WSN For Intelligent Street Lighting System:

In the paper authors propose to apply Wireless Sensor Network (WSN) to intelligent street lighting system. As a result of such a combination one obtains a system designed to increase functionality of  light installations for a wide range of applications and introduce a platform for new additional services, which meets current and future user needs.

Design Of New Intelligent Street Light Control System:

In China, the methods of time-control, optical-control and time-optical-control are in common used to control street lamp, particularly in small and medium-sized cities. But due to the backward lighting control and administrative method, the precision is bad, and the result of work is also poor. Through many kinds of sensor combination sense environment’s change, the multi-sensor exhibition can combinatory logically control the new intelligent street  light controller system.

Integrated System for Intelligent Street Lighting:

This reports the study and hardware implementation of a dimmable electronic ballast for high pressure sodium lamps, and a microprocessor-based system for control and energy measurement for this ballast, which uses a power line communications system to send and receive status and commands from another ballasts plugged in the same mains sub circuit.

WORKING

Auto Mode:

In auto mode, according to the traffic intensity and time of slots and also monitoring the weather conditions the nodes are being switched on/off .It monitors the need and thus saving power.

Case 1: pole2,4-Whenever there is not  much demand for  intensity the alternate  node provides lights. These settings can be predefined by analyzing the traffic congestion in a particular area and also according to sunset conditions differing geographically.
Case 2: 1,3,5- Similar reason as above.
Case 3: All the poles are working with 50% intensity.
Case 4: All the nodes are working with full power intensity, during the most traffic congestion or as per the urgent calls.

Manual Mode:

In Manual mode, system stores the parameters in computer about changes in environmental conditions  continuously like heavy rain visibility, faults , more or less traffic congestion or during foggy conditions. User can manually define each node with specific intensity factor as per requirement.

CONCLUSION

In this paper Intelligent street lighting system is described that integrates new technologies offering ease of maintenance and energy savings. The proposed system is appropriate for street lighting in remote as well as urban areas where traffic is low at times. Along with energy saving it also tackles with the problem of power theft. It is capable of taking corrective actions in case of unprecedented events  of climatic changes.
