Bus Backside Accident Alert System
Abstract
Microcontroller based "Bus backside accident alert
system" is mainly used to avoid the accident behind the vehicle, which
standing/running back side of the bus.
This project has contains two sections. These are
transmitting and receiving section. In transmitting section, one ultrasonic
sensor is used to transmit the signal. Similarly in receiving section, another
ultrasonic sensor is used to receive the signal.
The operation of this system is the ultrasonic sensor
transmits its wave continuously with minimum time delay and its power level is
set so that its rays reach only up to a certain distance strongly and it gets
reflected back if it strikes any obstacle. So now if any vehicle nears behind
this vehicle these ultrasonic waves gets reflected back and we can detect this
condition using the micro controller unit and we can avoid the accident.
Micro controller is used to record those signals and then
detects if there is any changes or variation in its normal operation. Then the
message will be sent to LCD display and the buzzer. The
Buzzer alerts the driver. Thus with in few microseconds we
are able to avoid the accident. future, this project will play an important
role in public
