FIRE SENSING ROBOT
INTRODUCTION
These days many problems are solved
by using electronic devices which detects and controls the errors up to some
extent. Many of the problems are handled using robots.
“FIRE SENSING ROBOT” is a project
used to detect fire automatically in a hall like space. Here the robot detects
the fire and moves near to it and tries to pour water. If it is not able to
control the situation, then it ON the buzzer and sends SMS to the predefined
numbers.
DESRIPTION
In this project we are developing a
robot which detects the fire automatically. Here we are using an LDR (Light
Dependent Resistor) to detect fire. The output of LDR is a resistance variance
dependent on light. This resistance is converted into voltage and taken into
ADC. ADC converts the analog voltage into digital bits which is taken into
microcontroller. Microcontroller controls the motion of the motor and moves
towards the fire. Once it reaches near to the fire, after few seconds it sends
an SMS to the predefined numbers.
8051 architecture based P89V51RD2 microcontroller
from NxP is used to implement this project. Microcontroller acts as the heart
of the project, which controls the whole system. It contains 1k RAM, 64k Flash,
3 Timers, 2 external interrupts, 1 UART, 32 GPIO’s, ISP programming support
etc. KEIL IDE is used to program the microcontroller and the coding will be
done using Embedded C.

SMS BASED ALERTING SYSTEM FOR TRAIN PASSENGERS
INTRODUCTION:
Circuit Diagram:
Possessing own transportation has become
more common nowadays. The number of vehicles on the road keep on increasing and
most of us are eager to own personal vehicle as we can go anywhere without
limitation.
In case we are unable to afford personal
vehicle, public transportation such as bus, train and cab is the most
convenient option for us to get ourselves to another destination from time to
time. In this project, we will concentrate on train only.
Undoubtedly, the existence of train has
reduced road traffic. Besides, it provides a low-cost transportation, which is
a means to the low-income family for traveling to another destination.
Most often, it is desired to travel in
train for long distance & reach the destiny in odd timings especially at
mid nights.
Most often, we will be busy in our own
daily work. So we need someone to remind about destination.
PROJECT
OBJECTIVES:
The
objectives of this project are:
Ø To
create an application that is able to estimate destination station and alert
the passengers through short message service.
Ø To
offer a convenient mobile information service, this ensures the passengers to
get the alert of destination station in the previous station.
Ø Main
objective is to alert the passengers. As the “mobile” is portable thing &
is now the best way of communication.
Ø So
we have chosen the “SMS” as the best service to intimate the people as even the
basic sets will support this facility. Hence better way to alert all class
people and is cost effective.
WHY IT IS
NEEDED?
As we have seen any
country of the matter more than 70% of people relay on public transport it may
be a big metropolitan city or small village with a small community of people.
Most of the people in this metropolitan city or village are the middle class
and low class people they are very much relayed on this public transport to go
to the various destination, as it offer one of the most cheapest mode so all
middle and low lass people relay on this to their daily activity.
There is a possibility that train
passengers travelling over long distance can miss their destination station and
reach unknown city or village especially at mid nights .It can lead to
frustration and disappointment.
So for those people this project could
brings a solution to overcome the above problem. The figure 1.1 shows the
condition of passenger travelling over long distance.
ABOUT THE PROJECT:
Below figure 1.2 shows the implementation block
diagram of “SMS Based Alerting System for Train Passengers”.
The
block diagram consists of Microcontroller Unit ( P89V51RD2), GSM Modem, MAX 232
IC, RS-232 port, 4x3 Key-pad, IR sensors, LCD Display.
The
following steps briefly demonstrate our project.
STEP1:-Passenger
enters the destination station number and phone number using a keypad while
taking ticket and LCD is used for displaying the user information. (Ref. figure
1.3)
STEP2:-Once
the passenger enters the train and starts his journey, the IR sensors situated before
each station senses the arrival of train, and sends the control signal or IR
status signal to Microcontroller Unit (MCU). (Ref.fig 1.4)
STEP3:-The
IR status signal is sent to the microcontroller (particular destination station
number which is predefined) enables the GSM modem to send SMS to the
passenger’s mobile by using serial communication (RS-232 port & MAX-232
IC). Figure 1.5 shows the SMS sent to passenger’s mobile from GSM modem.
ADVANTAGES & DISADVANTAGES:
Advantages:
Ø The
passengers can get arrival time of train.
Ø It
is helpful to identify the destination station very easily.
Ø This
can also be used for buses also.
Disadvantages:
Ø Velocity
of the train will not be same throughout the distance.
Ø Network
congestion.
Ø Reader
fails to read the tag from great distance if there is a rain or fog.
Conclusion:
Avoidance of missing the destination can
now be overcome by implementation of SMS based station alerting system within
the train and station. It uses the combined technology of sensors (sensing for
train arrival), GSM technology (for SMS alerting), programming skills for
interface of various circuits to a chip so called microcontroller. Related
circuits of various components and its interfacing circuit diagrams, related
issues, soft-wares used and related programs as a pictorial representation have
been documented in this book. To overcome issues related to sensors and other
areas theoretical models have been given in appendices. So by implementation of
such system information services remain fundamental to passenger satisfaction;
slight adjustments can be made for real time application using GPS (Global
Positioning System) tracking system.
After studying this report one can able
to build such a model for practical applications with some slight changes. In
this project we have implemented circuit for one-way communication i.e.
alerting the passenger from station site by collecting his/her cellphone number
at the ticket counter. It can also be extended for two-way communication i.e.
by sending the SMS from customer site to the application in the specified
standard format one can get the information related to train such as location
of train, arrival time. So if such application is implemented in real time then
it will be greatly helpful to the public.
One can even extend this application with
inclusion of other functionalities such as automatic announcement (within the
compartments in different languages inside the train), these services over
internet, etc., with expansion of memory and/or using database router for
storage of large customer data. Ideas and implementation of application are
still an open issue so that one can work on it. Different implementation will
come up with blend of different drawbacks, but proper standardization and depth
they cover in efficient and effective manner can lead to best successful
implementation; one such approach has been done in this report.

AGRICULTURE BASED ROBOT- E&C Project
INTRODUCTION:
India is agriculture based country. More than
70% of the people are the farmers. They grow rice, paddy, wheat, etc.
Agriculture is the backbone of our country. Till recently the farmers were
using age-old instruments in cultivating their lands. They themselves were putting
the manual labor. Hence there was not the labor- problem. There agriculture laborers
were skilled in their work. Their son & daughters were also trained in this
work from the beginning. And they continued that work. But now the youngsters
are attracted by the city life & jobs in the towns. They are not ready to
continue their family work. They have no interest in that also. Therefore the
poor farmers are facing the acute shortage of laborers. It has become a burning
problem. Many lands are left uncultivated.
So
more & more auto-machines & equipment are to be discovered.
Especially in spraying the pesticides to the farm, nursery, and these machines
which can save time and do the timely work are a must. In this respect robot
will be of great use. It will save time, money, human energy and manual labor.
It must be designed and manufactured in such a way that it must be the
friend-in-need of the farmers. If it is so single man can do such works and
innumerable uncultivated lands can be cultivated and the country will not
suffer from food-shortage. So we developed a prototype model of “Agriculture
Based Robot”.
PROJECT
OBJECTIVES:
The
objectives of this project are:
Ø It can be used to spray
pesticides to the paddy fields.
Ø It can also be sprayed to
more distance.
Ø We can control it by
sitting at home.
Ø It will reduce the gain
of human energy& manual laborer.
Ø It will save the
time& money.
Ø It can be used to spray
pesticides to the crop in the field and also nursery
WHY IT IS
NEEDED?

skilled in their work. Their son & daughters were also trained in this work
from the beginning. Farmer’s facing this type of labor shortage. So we are
introducing the robot to solve all these type of problems. The key-features of
our robot is,
Ø Due to the advancement in
technology we are using our beautiful project Agriculture Based Robot. It helps
us for fast working, consumes our precious time, and saves human power.
Ø So our main intension is to bring
new change in the field of agriculture and to improvise India in agriculture
and also improve Indian economy.
FUTURE SCOPE:
Our robot can be implemented as climbing
robot in future. And spray the pesticides to the areca-nut trees. Also we can
make it as plucking robot for the plucking of areca-nuts. In future it can be used as areca-nut
plucking by making small changes in hardware parts and software parts. We can
also add features like weed plucking. We can also use it as a security for our
farms. It can be used to even do daily house hold activities. Due to this robot
we can reduce human efforts and human work. Due to lack of human resources we
can use this robot to reduce human work and manual laborer problems in the agriculture
field.
The below three figure shows the 2 options
are available to implement our robot. That is, make it as walking robot or
climbing robot. To make our robot as climbing robot then, there are two type
options. That is, itself the robot has climbing parts and another method is to
use the climbing machines. We can implement all these to robot then it can be
easily climbing the coconut as well as areca-nut trees.
