SUMMARY
Crushing vehicles is natural, it is
impossible to be avoided. Crushing vehicles can happen because of slippery
road, sleepy and drunk. This phenomenon causes harm and leaves damages for the
other vehicles, innocent’s citizens, structure and to the people who live
around the streets area. Preventive measures are necessary to minimize the
casualties of such phenomenon, hence, technology is best known in providing
help and assistance for mankind. This system detects danger when the vehicle is
near to danger like wall, object or structures and then the system will pull
over or break to avoid the crush or bump in the other structures. A
micro-controller is utilized to control the functions of the device. A warning will
be given once the vehicle reaches the certain measured or distance. The device
transmits information about the measured or distance status and data will be
transmits to the LCD to know what is distance of the vehicle in front of you. The
ability to receive information on the distance measures to react imminent
danger in an effective manner. Once the alert is received in the monitoring
center, the vehicle must respond to it immediately. Being prepared for crushing
incidents does not only keep the citizens safe, it can also help minimize the
incidents and reduce the impact of the crush
INTRODUCTION
Project Context
One
of the problems that often occur worldwide is incidents in vehicles. Incidents
in vehicles can happen because slippery road, sleepy and drunk. This phenomenon
causes harm and leaves damages for the other vehicles, innocents, structure and
to the people who live around the streets area. These disasters cannot be
avoided but can reduce by using this system that can minimize its impact or be
avoided. One way is to monitor the rise of distance measure and to provide
advance warning during the occurrence action. The driver of the vehicle will have
time to prepare and to avoid incidents.
Philippines are known to be very
prone to vehicle incidents, that are why the proponents decided to design and
develop a ultrasonic distance system. This project utilizes a device using a
ultrasonic sensor, Arduino and a LCD. The device will be the one that detects
and monitor the distance of a certain area. While the LCD will be used to know
what is the distance of the other object.
There is also an alarm system that
is divided into 4 colors; orange, green, yellow and the critical color red.
When the device detects that the vehicle is far from the object or wall, it
will deliver or send to the LCD about the status. If the vehicle is near from
the object or wall another data will send to the LCD. When the vehicle is in
the nearest point it will trigger the sound alarm and the vehicle will stop.
Purpose and Description
The
study aimed to reduce the accidents in the Philippines especially in the driver
that are in drunk, sleepy and other circumstances.
Objective of the Study
To
achieve the goal of the study, the project design is to develop a device that
can minimize the accidents:
·
To minimize the
accidents
·
To avoid destroying
other structures
·
To ensure the safety of
the driver
·
To identify the
distance measure in front of your vehicle
Significance of the Study
The completion of this project is
seen to be benefit to the following:
Drivers
·
This would help the
drivers to avoid accidents. If they are drunk, sleepy and the road is slippery
the device can help them to avoid the incidents and accidents.
Citizens
·
This would serve as
their safety device, as you can see this device is for the vehicle to avoid
crushing on other citizens walking along the street.
TECHNICAL
BACKGROUND
This figure shown below shows the
graphical representation of the whole process of the proposed project. First
the ultrasonic sensor senses the distance, and then it will be processed to the
Arduino and LCD. Arduino is the microcontroller that will be the responsible of
sending the message to the LCD to have the display. There is a warning system
assign to give an alarm whenever the distance is near to other structures.
RESULT AND DISCUSSION
Data Gathered
After
developing of our device, the device can stop immediately if the vehicle is in
danger like crushing or bumping on other vehicle. This also LCD to know what is
the distance in front of your vehicle. Lastly, it also has an alarm system to
know that other vehicle or structures are so near.
Testing and Validation
The
project ULTRASONIC DISTANCE SAFETY MEASURE is successfully finished using
Arduino. The objectives of the project are reached as projected and develop the
safety of a vehicle and the driver. The project also improves the incidents and
accidents in our country. The project would benefit the vehicle owner and to
the citizens. With the aid of this device, this can minimize the accidents and
incidents.
Conclusion
It
has been concluded that all objectives that have been listed were successfully
reached, particularly the following:
1. Design
a software program that can solve the proper distance of the vehicle and the
structures.
2. Design
a software program that can minimize accidents and incidents.
3. Make
a miniature to know what is important of the device to a vehicle.
4. Established
a system where you can try your device.
