This document describes a railway safety system that alerts authorities to fires on trains. The system has three main sections: at signal points, on trains, and at railway stations. A microcontroller controls the whole system and provides instructions to external devices. The system helps avoid accidents when trains pass red signals. It senses fires, automatically fights fires using extinguishers, and implements a real-time embedded system with hardware and software interaction for railway safety.

3. The main aim in designing a system
Which alerts the railway authorities when any
fire accidents occurs in the train and this system
also provides an immediate effect which
controls fire using controlling system.
The project mainly helps to avoid accidents
which usually occurs when trains crosses the
signal although when it is indicating RED
color to stop it.

4. This system has three main
sections:
at the signal point
in the train
at the railway station

6.  A microcontroller is a small computer on a single
integrated circuit consisting of a relatively simple CPU
combined with support functions such as a crystal
oscillator, timers, watchdog timer, serial and analog I/O
etc.
Microcontrollers controls the whole system and
provides the instructions to the external devices.

7. REGULATED POWER SUPPLY
 Every embedded system requires dc voltage and that that will
be 5v supply
 We are getting 230v, 50 Hz in our house hold applications.
We can be used to operate the home appliances like T.V,
cooler, fan, light’s
 Digital electronic devices need digital supply and we can
get supply from regulated power supply block

10. Software’s used:
 Express PCB – for designing circuit
 PIC C compiler - for compilation part
 Proteus 7 (Embedded C) – for simulation part

11.  Low power consumption.
 Fire sensing.
 Auto fire fighting (fire Extinguishers).
 Highly sensitive.
 Implementation of multi point receiver.
 Implementation of real time embedded
system, which involves hardware and
software interaction.

12. Conclusion:
Integrating features of all the hardware components
used have been developed in it. Presence of every
module has been reasoned out and placed carefully,
thus contributing to the best working of the unit.
Secondly, using highly advanced IC’s with the help of
growing technology, the project has been
successfully implemented.Thus the project has been
successfully designed and tested.
