ABSTRACT

Fire accident is a serious problem in our world especially the populated and illiterate region. Fire accident mainly takes place due to unknowingness of safety precautions about safe travel and also some technical consideration during travel. So the railways department should take the precautionary action to prevent the unnecessary damages and deaths

Explosive threats in train:

The Guwahati-bound train from Bangalore, Guwahati-Bangalore Express, was scheduled to arrive at Chennai around 05:30 AM IST, but it had arrived late around 07:05 AM IST. While the train was stationed at Platform 9 of the railway station, two bombs exploded at the junction of S4 and S5 coaches at 07:15 AM IST. Upon hearing the explosion, panicked passengers rushed out of the train. One of the bombs had exploded under the seat of a 24-year-old woman.

EXISTING:

In existing system, the communication between the compartments in train takes place by unreliable wired connection. Unfortunate accidents may terminate the communication by damage which leads to human’s death. And no fire safety and explosive alarm with prevention system is installed, it was done by manual. So manual is time taking and no assurance.

PROPOSED:

          In this system, for continuous communication the wireless communication has been preferred. The data’s and acknowledgement signals are handled by the RF Transceiver due to that low power consumption. Each and every compartment are networked with engine of train which acts as master node of the train and other are acts as slaves.

Working:

          When the train unit (engine and compartment motes) has been turned on they have formed a network for communication. Each compartment in train having water sprinkler and flame sensor has been placed to detect the fire and explosive detectors to fine exposes. The engine unit has a display unit and alarm too. If the sensor threshold value exceeds, then automatically the compartment unit given fire alarm and the water sprinkler system will turn on and this fire accident location is sent through wireless to the engine unit. When the engine unit receives the information, it automatically will stops the train ,which prevents further fire spreading to another compartment and saves peoples too  the alert will be given to engine unit.

At the same time the driver can know the alert and the fire can be automatically prevented. Similarly if any explosive detected in the compartment, the explosive alert alarm will sounds and alert the passengers as well as operator. The locomotive automatically stops and locate the spot of the explosive. An Auto de-clamping system also implemented to separate the compartments it is done for safer.
