INTRODUCTION
This project is designed so that students can understand the technology used in the now a day’s driver less metro train which is used in most of the developed countries like Germany, France, and Japan etc. These trains are equipped with the CPU, which control the train. The train is programmed for the specific path. Every station on the path is defined; stoppage timing of the train and distance between the two stations is predefined. This is very wonderful project to control the working of the train without driver. These train are equipped with the CPU which control the train.
1. 8051 Microcontroller
2. ULN 2003
3. Stepper motor
4. LCD
In this project we try to give the same prototype for this type of trains. We are using ATMEL microcontroller 8051 to control all the function as CPU. Microcontroller controls the rotation of motor. First the motor is controlled and name of each station is displayed over LCD and accordingly the different delay for each station is provided. So this project works for metro train without driver. The motion of the train is controlled by the Stepper Motor, for displaying message in the train we are using Intelligent LCD Display of two lines. The train is designed for three stations, named as New Delhi, Noida, and Greater Noida. The Stoppage time is of 3
Sec and time between two consecutive stations is 6 sec. There is a LCD display for showing various messages in the train for passengers. There are indicators, which are used to show the train direction i.e. UP path and down path. Before stopping at station the train blows the buzzer. It also includes an emergency brake system due to which the train stops as soon as the
brakes are applied and resumes journey when the emergency situation is over.
WHAT IS EMBEDDED TECHNOLOGY
Embedded technology is software or hardware that is hidden embedded in a large device or system. It typically refers to a fixed function device, as compared with a PC, which runs general purpose application. Embedded technology is nothing new. It all around us and has been for years. An early example of embedded technology is the engine control unit in a car, which measures what setting to give the engine. Your coffee maker has embedded technology in the form of a microcontroller, which is what tells it to make the coffee at 6 a.m. the vending machine has it too. Overall, billions of devices woven into everyday life use embedded technology.
In the past embedded technology existed in standalone device vending machines and copiers that did their jobs with little regard for what went on around them,. But as technology has learned to connect device to the internet and to each other, embedded technology potential has grown. Suddenly it is and what actions those connections let them perform. Cell phone companies figured that out a long time ago, which is why cell phones are cheap and the service, plans are expensive. It is not the phone itself that matters, but the connectivity to a vast network of other phones, other people and the internet. Until you download software that lets you find a local restaurant or mange your finances. Let say you make freezers the big, expensive kind that grocery stores buy. You sell ne and you are done with that customer. When it brakes the customer calls a service person, who probably comes from somewhere other than your company. But let us say that freezer knows that it is about to go on the fritz. Let say three refrigerator alerts the customer before it breaks. Better yet, let us say the freezer alerts the manufacturer and you are able to send a service person to do preventative work and save a lot of haagen- dazs from melting. Embedded technology allows all of that to happen. You, the freezer company have transformed yourself from a product company to product and services company. The possibilities go beyond that programming device to communicate with businesses can eliminate the need for costly call centers. Copy machines that can order their own replacement cartridges will save businesses time and money. Remember, the fact the technology is
embedded is not what important, and neither is the device.
