A SAFETY SYSTEM FOR ACCIDENT MONITORING
WITH BLACK BOX

2. ABSTRACT
• Traffic in our country is increasing day by day. Many people are not giving a good response for
the traffic rules in many places.
• Mainly accidents happens due to over speed and careless driving. Especially, in the school and
the college zone, people are hesitating for decreasing the speed to its limit.
• This is embedded project to indicate the over speed and to control the vehicle in the over speed
condition. This is constructed with the wireless communication. Given below is the block
diagram of the project.
• We are using PIC16F877A which is Programmable IC Microcontroller. To check the drunk and
drive we interfaced Alcohol sensor, and accident sensor indicate the occurrence of accident and
alert the public via alarm.
• The accident location using GPS. If the accident is a minor one then driver can press the reset
switch and drive normally.Accelerator, brake clutch and steering position sensor indicate the
position of accelerator, brake clutch steering respectively.
• We can monitor and control all with the help of IOT mobile app.

3. INTRODUCTION
• The main purpose of this paper is to develop a prototype of the vehicle black box system VBBS
that can be installed into any vehicle all over the world. This prototype can be designed with
minimum number of circuits.
• The VBBS can contribute to constructing safer vehicles, improving the treatment of crash victims,
helping insurance companies with their vehicle crash investigations, and enhancing road status in
order to decrease the death rate.
• Many police cases related to road accidents remain pending due to unknown reason of an
accident. To avoid these problems, a black box is designed which is used to analyse the status of
the vehicle at the time of occurrence of accidents.
• Black box is a digital electronic device, which records and store vehicle speed, real time and
vehicle's other status information. It helps to discover and to analyse the reason of an accident
easily and to settle many disputes related to car accident such as crash litigation, insurance
settlements.
• It can be used to not only reconstruct what happened before an accident by Insurance agents and
police but improve vehicle design, roadway design and emergency medical service by
automakers, government and hospital. Hence a combined system is essential to provide the
solution for all the above problems).

4. EXISTING SYSTEM
• The most common and well-known systems for accident monitoring with black box
• Flight Data Recorder: It is a black box that records crucial flight data and voice communication
between the cockpit crew members. The flight data recorder (FDR) is designed to withstand
extreme conditions and can help investigators understand what went wrong during an accident.
• Event Data Recorder (EDR): EDR is a black box that records critical data from a vehicle during a
crash. The device records information such as speed, braking, and seat belt use, and can provide
insight into the cause of the accident.
• Automobile Event Data Recorder: Similar to the EDR, this device records data from a vehicle during
a crash. It can provide important information to investigators about the cause of the accident.
• Overall, these systems for accident monitoring with black box are critical in understanding the
cause of accidents and preventing them from happening in the future.

5. PROPOSED SYSTEM
• In this project we’re going to monitor the accident with black box. Here it consist of various sensors
namely, Accelerator sensor ,brake sensor , clutch sensor ,steering position sensor and accident sensor .
• All the above mentioned sensor is used to analyze the condition of the vehicle .
• With the help GPS , location of accident occurred place to be located and stored for future purpose.
• If the driver felt it was an minor accident at the time he able to press the reset key , and the continue
driving normally.
• Once the major accident occurred after sensor detected that alert system alerts the people through
buzzer
• All the data are updated on the IoT cloud instantly for monitoring and for future purpose using IoT
mobile application.
