Unmanned Railway Gate

The hardware requirements are crucial to the system development, consisting of physical servers and other peripherals. These components are the legs and limbs of the system. The hardware section of the system will accept input, and process the input in a way specified by the design, and returns an output (Blundell, 2008).

ii) Processor I/O : Data may be transferred to or from a peripheral device by

In these days security is more important, not only from unwanted visitors but also keep children safely within the confines of the garden or the front yard. We can’t say there is 100% guaranteed for anything in life but sliding gates helps to keep you and your family safe in a small but in significant way. Simply we can say, they stop unauthorised people or vehicles to enter your courtyard.

Primary difference between an embedded system and a conventional computer system arises from their external connections:

A gated driveway is something that many people love having. It keeps people that you want out, out. It keeps animals that you want inside your yard, in. The thing is, for most people it also means that you must get in and out of your vehicle several times to let yourself in and out of your yard. When it is raining, you may not want to deal with it. They are also very difficult to deal with and require you to open up double sides or have one very large gate that is heavy to swing closed. That is why people are now choosing a better way to have a gated driveway. They are using sliding gates that use sliding gate track and hardware to make their gated life less complicated.

A garage door is one of the most basic, yet most important requirements of your everyday life. When you get ready for your office and open the door to your garage with just a flick of your garage gate opener remote, you never realize what an essential tool it is. However, when something goes wrong with your garage gate opener and you have no option of getting to your car, and you are getting late to your office, you realize how important it is to your daily life. Thus, when your garage gate begins to malfunction, it is important that you perform the garage door repair at the soonest.

We discuss the I/O methods and services which an operating system performs to run the applications in the incarnation of I/O interface.

Partial reconfiguration is a boon to enable changing of static modules of device at runtime and allowing the application to be created user specific and flexible to the environment. Partial reconfiguration is very much useful in building of memory architecture for reuse of space efficiently and so that the system works faster and better, it is also helpful in communication sector for end to end addition of encryption while transmitting and receiving of data, building of emulators,

An operating system is an interface between a user and the hardware of a computer. It is just a set of software that manages computer hardware and controls the operations on the computer. Operating system is the base of the application programs because they cannot contact the hardware directly. It does not do any work itself, it just provides an environment in which the other programs on a computer can run. Therefore, when a user enters or sends a command the operating system makes sure that the command is executed or not, if not it displays a message explaining the error. Without operating system a computer is of no use it is just a metal block.

Arduino interface sheets give the engineers, artists, designers, hobbyists and anyone who tinker with development with a low-cost, easy-to-use advancement to make their creative, interactive objects, useful errands etc. A whole new sort of endeavors can now be produced that can be controlled from a PC.

This powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS FLASH-based 8-bit microcontroller packs Microchip's powerful PIC® architecture into an 40- or 44-pin package and is upwards compatible with the PIC16C5X, PIC12CXXX and PIC16C7X devices. The PIC16F877A features 256 bytes of EEPROM data memory, self programming, an ICD, 2 Comparators, 8 channels of 10-bit Analog-to-Digital (A/D) converter, 2 capture/compare/PWM functions, the synchronous serial port can be configured as either 3-wire Serial Peripheral Interface (SPI™) or the 2-wire Inter-Integrated Circuit (I²C™) bus and a Universal Asynchronous Receiver Transmitter (USART). All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications.

I chose embedded system design unit due to my inordinate interest in embedded microcontroller programming. It was one of the requirements of the unit to build a GPS enabled device that meets the specified requirements for its use in the recreational sport Geocaching. Geocaching is a modern day treasure hunting or letterboxing game which basically uses the latest GPS technology to track and find items located in a remote place, with GPS coordinates provided to the user who is playing the game. This sport is gaining a wide popularity among the global audience. As part of the course structure, I was asked to develop a GPS enabled

The most useful and better approach is divide the task into small components /modules instead of having one monolithic system so that the operating system can function properly and can be modified easily. Input, output and functions should be clearly defined in each of the system modules as far as we can finally come with large and complex system.

A huge variety of microcontrollers already exist on the market. After comparing several types of boards, including ATMEL, INTEL and PIC based ones; an ATmega328 based ship was assigned for the implementation of our prototype: The Arduino Pro, which is cheaper in price and smaller in size than the other boards, and satisfies perfectly our needs.

The system is very simple in design and to implement. The system requires very low system resources and the system will work in almost all configurations. It has got following features
