“SOLAR SENSING AUTOMATIC STREET
LIGHTING CONTROL SYSTEM”
After seeing there is a lot of wastage of electricity
in street lights. Industries, we have experience that there is
a need of
system which will save
electricity. Now a day some of
peoples had implement solar system
which take energy from sun and
store it and give a
light but it is rather costly
by seeing those system
we have LDR sensors so in place of solar we
have used LDR sensors which will
automatically detect darkness
and glow so
there is no at all costing as compared
to solar of others
system.
The proposed system had to meet certain
criteria;
No need of
person going to
destination to change.
Service cost is
low.
Support any type
of language for programming.
Implementation cost is
low as compared
to other system
is not connected directly to it.
Support for new
types of service
and facilities.
“From this project we are trying to
save the wastage of electricity. In increasingly uncertain world electricity
required is more so we can save more electricity and other works can be done
easily related to electricity. The focus is “AUTOMATIC STREET LIGHTS” i.e. new
method of implementing light and saving cost.
The main object of our project is
to save more electricity i.e. saving of light which glows in day time also.
Here we are going with three parameters
microcontroller, LDR sensors, and relays. We have developed this project. It
will be very useful for Industries, Gardens,
Airports, most important for street
light, for achieving this we choose LDR sensors which will automatically sense
conditions. As in dark condition it will automatically glow so following there
are three mode in 1st mode in time from 6 to11 all light were glow
as people of traffic are much , in 2nd condition zigzag mode is
given which will operate in time from 11 to 2 and now, in 3rd
condition or mode lights were glow in alternate mode in time from 2 to 4 .Thus
now as people comes for walking from 4 am onwards it goes to first condition on
or all light glow thus in this way we are programming in microcontroller
through help of assembly language.”
WHAT IS OUR PROJECT
Automatically Controlled Street
Lights.
Developed to control through
programmable IC (AT89C2051)
Programmable and Cost Saving.
IDEA BEHIND IT
Combination of hardware and software.
Real Street Lights.
FACILITIES
It will automatically work according to the
modes given no need of person going to the destination and the modes.
Controlled by
Programmable(89C51)
LDR sensor
Sensor circuit
OVERVIEW
Connect to Male AND Female connector.
All electrical parts
Different logic for each mode.
Target is to save more power electricity and
cost.
DEVELOPMENT TOOLS
Pony Programmer
Burning Kit.
SOFTWARE REQUIREMENT
Assembly language
PURPOSE OF ASSEMBLY LANGUAGE
In software
we are using Assembly Language through which we are able to give controlled
command. As it is in 0 and 1’s form no need to convert it into 0 and 1’s
because is pony programmer by which we are programming and compiling it. After
these we are burning it into IC through burning bit we can lock these after
burning.
HOW HARDWARE WORKS
First the program is burn in programmable
(89C51).
8 BIT MICROCONTROLLER ATMEL 89C51
INTRODUCTION
Microcontrollers these days are silent workers in many apparatus,
ranging from the washing machine to the video recorder. Nearly all of these
controllers are Mask programmed and therefore are of very little use for
applications that require the Programs to be changed during the course of
execution.
Even if the programs could be altered, the information necessary to do
so an Instruction set, an assembler language and description for the basic
hardware is either very difficult to obtain or are in adequate when it came to
the issue of accessibility. A marked exception to the above category is the
atmel 89C51 microcontroller belonging to the Atmel family. This microcontroller
has features that seem to make it more accessible than any other single chip
microcontroller with a reasonable price tag.
The 89C51, an
8 bit single chip microcontroller has got a powerful CPU
Optimized for control applications, 64K program memory
address space, 64K data Memory address space, 128 bytes of on chip RAM
(read/write memory), for 8 bit bidirectional Parallel ports one full duplex
serial ports two 16 bit timers/counters and an Extensive interrupt structure.
The 89C51 is a second generation 8-bit single chip
microcontroller. The 89C51 provides a significantly more powerful architecture,
a more powerful Instruction set and a full serial port.
The
89C51 is a complete microcontroller. We will start our discussion on the
programming model by looking at the architectural block diagram. As we can see
the external connections very simple.
There
are 31 pins needed by the four 8 bit bidirectional ports. Eight additional pins
are provide power, allow you to connect a crystal clock and provide a few
timing and control signals. The architecture includes the ALU, the accumulator,
the stack pointer, a block of registers and a general purpose register-the B
register.
All these devices are
connected to the 89C51 internal 8-bit data bus. Each I/O port is also connected
to the 8 bit internal data bus through a series of registers. These registers
hold data during I/O transfers and control the I/O ports. The architectural
block diagram also shows the 89C51 ROM and RAM.
