RAILWAY ACCIDENT CONTROL

hi,
i am happy to say that i and my friend saravana pandian won the first prize in the Mepco Schlenk Engineering College, Sivakasi...i would like to share that papers abstract with you all...

EMBEDDED BASED RAILWAY SAFETY SYSTEM

-life is priceless, life protection is cheap.

Right from the splendid starting of 2010 to July 19, 2010, Hundreds of precious lives have been taken from our mother INDIA, in thirteen train accidents. The Gyaneshwari Express train derailment and Sainthia train collision are the two major accidents this year, which killed 223 passengers….

Trying to be responsible citizens of this nation, here we propose a design to reduce these accidents.

“Few can foresee whither their road will lead them, till they come to its end.”

-J.R.R. Tolkien (English Writer)

The main drawback with locomotive system in use is, even if the pilot identifies any problem in the rails, he needs at least 500 meters to stop the train using emergency braking systems, which is practically impossible. So, we send our ROVER 500 meters ahead of the train to check for any obstacles or damages found in the track (rail) using sensors and intimate to the train as well as to the nearest station via Radio Frequency with the help of a microcontroller.

ACCIDENT CONTROL FOR AUTOMOBILE

Friends,
here is my second paper with my friennd Rajesh khanna... EMBEDDED BASED AUTO MOBILE COLLISION PREVENTION... this paper is entirely different from my last paper... expect the title everything is on our own... it is completely our paper... we took nearly a weak to complete this paper... while working on this paper we learnt many recent concepts like range finder, how to select controller, braking systems, ABS, etc... it was very enjoyable and interesting to us...
And this paper got selected in ANNA UNIVERSITY, COIMBATORE and KARUNYA UNIVERSITY..
More important is that we won second prize for this in ANNA UNIVERSITY,coimbatore...
here is that interesting paper for you

EMBEDDED BASED AUTO MOBILE COLLISION PREVENTION

Most of the automobile accidents could be avoided if the brake had been applied at proper time and at proper distance. In this paper we are using embedded system which could be embedded in the automobile to remove the driver’s reaction time from the situation. The system, consisting of controllers, which analyzes possible accident situations based on the vehicle separation distance, their relative velocity and a static friction coefficient that represents the road conditions. The controller determines the sufficient brake pressure required to prevent collisions while providing a smooth ride for the vehicle’s passengers.

Our work is to design controller to automate and optimize the application of brake pressure to an automobile’s brakes at proper time. So first requirement implies that the two vehicles should never have any physical contact, while the second one implies that the brakes should be used only in the amount necessary, e.g., they should not undergo large excursions to make small adjustments.

In general, if the automobile in front decelerate, then the vehicle behind it must decelerate to avoid the collision. Here, the controller tracks the vehicle and have its velocity as reference and applies the appropriate brake pressure at the proper time. So, the controller automatically decelerates to match the velocity of the tracked vehicle and avoid a collision.

IMPORTANT PARAMETER

The parameters that we took to avoid collision are

separation between the two vehicles
velocity with which they approach each other
surface conditions

For calculating these three parameter, Laser range finders could provide the first two measurements, while wheel-slip sensors currently used for automobile Traction Control Systems or Anti-lock Breaking systems (ABS) could estimate could estimate the third measurement.

MODULES

we have three modules, they are

distance finder
intelligent control module
braking system

working
here,the distance finder finds the distance between the vehicles and reports to the controller.The controller processes data and calculates the percentage of braking. this braking is coupled with actual braking of the ABS unit..

BLUE EYES TECHNOLOGY

This is my first paper.. with my friend saravana pandian.. We just want to learn and do something.. Fortunately we got this topic and we took seminar on this topic in VELAMMAL COLLEGE OF ENGINEERING AND TECHNOLOGY,madurai.. I'm saying it as seminar because we understood the concept and we explained it there,we didn't add anything new to it..
Everyone there were interested to listen this because it goes like a HOLLYWOOD scene....
HERE IS THAT SCENE FOR YOU... GO AHEAD...

BLUE EYES TECHNOLOGY

Can we make computers "see" and "feel"?

Is it possible to create a computer which can interact with us as we interact with each other? For example imagine in a fine morning you walk on to your computer room and switch on your computer, and then it tells you “hey friend, good morning you seem to be a bad mood today. And then it opens your mail box and plays your favorable songs and tries to cheer you. It seems to be a fiction, but it will be the life in the near future. We all have some perceptual abilities. That is we can understand each other’s feelings. For example we can understand ones emotional state by analyzing his facial expression. If we add these perceptual abilities of human to computers would enable computers to work together with human beings as intimate partners. The “BLUE EYES” technology aims at creating computational machines that have perceptual and sensory ability like those of human beings.

This is achieved using the facial recognition, eye gaze pointing, speech recognition and other sensors

Principle behind the blue eyes

In order to create such a smart computer, the computer must understand user’s emotions and interest without giving any manual information from the user describing his emotional state or interested.

1. To achieve this we use the facial recognition and other physiological measure to detect the user’s emotional state.

2. To detect the user’s interest and to make the users pointing work easier, we go for MAGIC eye pointing technique.

3. To give the ability for the smart computer to understand the user’s language and perform operation as per his speech, we add speech recognition alone with emotion and magic technique.

Application

Ø Generic control rooms(system can be applied in every working environment requiring permanent operator’s attention)

o power station

o Captain Bridge

o Flight control centers

o Operating theatres-anesthesiologists

Ø The Simple User Interest Tracker (SUITOR)

Ø Blue Eyes can be applied in the automobile industry

Ø Video games

Future application of blue eye technology is limitless.

This ensures a convenient way of simplifying life by providing more interactive and user friendly facilities in computing device. In near futures, ordinary house hold device-such as television, refrigerators and ovens may be able to do their jobs when we look at them and speak to them.
