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.

COMPONENTS USED
1.      Microcontroller - P89V51RD2 – Phillips.

SMS BASED ALERTING SYSTEM FOR TRAIN PASSENGERS

 INTRODUCTION:

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.

 Circuit Diagram:

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
