Most of the
accidents in high-ways are happening due to the drowsiness of drivers, most
often this symptom is found in long distance truck drivers, these drivers may
take some time to recognize the opposite vehicle, which is running at low
speed, resulting accident. This kind of accidents may happen due to the drunken
drivers also. So to increase safety an electronic warning system is essential
to alert the drivers. This kind of system can be installed in all types of
vehicles, especially in commercial vehicles, so that accident rate can be
minimized. The warning system designed here can be called as driver attention
system, which raises an alarm and energizes the display board automatically
when the following vehicle came near to the in-front running vehicle.
The project work keep distance
warning system that is designed for Automobiles, any vehicle ranging from motor
cycle to heavy duty truck can adopt this system. This alerts the following
vehicle whenever it came very close to the ahead vehicle; thereby to some extent accidents can be avoided.
The circuit is designed such
that whenever the infrared signal is interrupted, logic high signal is
generated and it is fed to microcontroller, on receipt of this signal, the
controller activates the display board and alarm automatically.
This system is best for guiding
the perimeter of a house or a business center the points where an intruder
would enter the building. In this system IR sensor is used to detect the
intrusion. Similarly the vibration and temperature sensors recognize vibration
disturbances and accidental fires respectively.
This project provides an efficient
and economical security system. This system finds applications in industries,
banks and homes.
This system is a rapidly growing
field and there are new and improved strategies popping up all the time. For
the most part these systems are all built around the same basic structure, a
central box that monitors several detectors and perimeter guards and sounds an
alarm when any of them are triggered.
Incorporating the features discussed below can further enhance the
system
v This
system can detect intrusion only at
discrete points. This system detection feature can be extended to scanning a complete area. Thus the
intrusion into the building can be detected with much more efficiently.
v The redialing feature can also be incorporated such
that if the call is not put forward the first time, the auto dialer will dial
the same number until the call is successfully completed.
v A pre-recorded voice message can delivered to the
owner notifying him about the intrusion into the premises.
v The addition of the above discussed advancements
certainly builds this project into a much flexible and reliable security
system.
