Abstract :- Automatic Street Light Control System is not
only easiest but also the powerful technique. Relay uses as a
automatic switchin this system. It releases the manual work
atmost upto 100% . As soon as the sunlight goes under the
visible region of our eyes this system automatically switches
ON lights. Light Dependant Resistor (LDR )is a type of sensor
which actually does this work and senses the light as our eyes
does. As soon as the sunlight comes, visible to our eyes it
automatically switches OFF lights .
Such type of system is also usfull for reducing energy
consumption.
INTRODUCTION
The main consideration in the present field technologies
are Automation, Power consumption and cost
effectiveness. Automation is intended to reduce man power
with the help of intelligent systems. Power saving is the
main consideration forever as the source of the
power(Thermal, Hydro etc.,)are getting diminished due to
various reasons. The main aim of the project is Automatic
street power saving system with LDR; this is to save the
power. We want to save power automatically instead of
doing manual. So it’s easy to make cost effectiveness. This
saved power can be used in some other cases. So in
villages, towns etc we can design intelligent systems for the
usage of street lights.
NEED OF SYSTEM
The traditional implementation and organization of street
lighting have no possibilities for improving and
development any more. The dynamic changes in economy,
energy supplies and ecology on a national, Indian and
world like scale require an adequate modernization of street
lighting. However, this would be possible only with a quite
new functional conception which in fact means adaptability
of street lighting. Simultaneous ensuring of the conditions
of safe traffic and decreasing the energy consumption and
operational costs could be realized in conformity with the
constantly changing parameters of the environment. In
conformity with the 24 hours change of daylight, the highly
changeable traffic, the variable meteorological conditions
and some extreme situations on the roads, the intensity of
street lighting should change in a dynamic manner.
III. SYSTEM ARCHITECTURE
Technical devices and methods that are offered by
technical progress will be necessary obviously for the
realization of adaptive lighting. The tender documentation
states the goals of the E-street Project and the ways of their
implementation. It describes the system structure and the
technical requirements towards its subsystems: roadside
equipment, power system, local control system, central
supervisory system and communication network. The
content and project requirements for the implementation of
Adaptive street lighting - project management, quality
assurance and installation requirements -
