The objective of this project is to manage the control system of railway gate using the microcontroller. When train arrives at the sensing point alarm is triggered at the railway crossing point so that the people get intimation that gate is going to be closed.
AT89C51 Microcontroller: The Micro controller (AT89C51) is a low power; high performance CMOS 8-bit micro controller with 4K bytes of Flash programmable and erasable read only memory (PEROM).
INTRODUCTION ON EMBEDDED SYSTEMS
An Embedded system is a combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a specific function.
The common design requirement include –
Number of Units
To run the electronic gadget at home it is provided by some power supply. The microcontroller used (at89c51) requires 12v D.C supply.
For design of a regulated power supply components used are:
Regulated IC chips.
Hence the Unmanned railway gates operate according to the data input from sensors to microcontroller. First an alarm is triggered and then the gate is operated.
