ABSTRACT

This demonstration shows how to effectively collect and manage information obtained from car black

boxes in vehicular networks. The car black box is a vehicle-based CCTV which records video images,

sound, GPS position, speed, and time. These data can be used for accurate car accident investigation and

some public crimes prevention. However, there are important issues such as user privacy and a data

management for a vehicle-based CCTV records. The proposed evidence collection system can reduce driver

privacy concerns and communication and management overheads. Our contribution is that we propose a

feasible and useful scenario for public safety

of black box is audio and video recording longitude of car, date of accident, time of accident, car speed and

head to a specified number

1.3 PROPOSED EXISTING SYSTEM

As per the National Crime Records Bureau (NCRB), in the year 2013 there were 440,123 road accidents

resulting in the death of 136,834 people .The incidence of accidental deaths increased by 44.2% in 2012

from 2013. This figure translates into one death every five minutes on Indian roads and is expected to

escalate to two death every three minutes by 2020.the death of people might be reduced if emergency

medical help was provided them immediately.

Beside this no evidence are available for a 48% to 50% of an accident ,due to this lots of problem take place

in insurance time and the data can be used against car owners, to find fault in accidents or in criminal investigations.

That why we develop car black box for evidence collecting and providing emergency medical help to an of

accident place.

FIG 1: MICROCONTROLLER

The 89S52 has 4 different ports, each one having 8 Input/output lines providing a total of 32 I/O lines. Those

ports can be used to output DATA and orders do other devices, or to read the state of a sensor, or a switch.

Most of the ports of the 89S52 have 'dual function' meaning that they can be used for two different functions.

The first one is to perform input/output operations and the second one is used to implement special features

of the microcontroller like counting external pulses, interrupting the execution of the program according to

external events, performing serial data transfer or connecting the chip to a computer to update the software.

Each port has 8 pins, and will be treated from the software point of view as an 8-bit variable called 'register',

each bit being connected to a different Input/output pin.

There are two different memory types: RAM and EEPROM. Shortly, RAM is used to store variable during

program execution, while the EEPROM memory is used to store the program itself, that's why it is often

referred to as the 'program memory'. It is clear that the CPU (Central Processing Unit) is the heart of the


12

microcontrollers. It is the CPU that will Read the program from the FLASH memory and Execute it by

interacting with the different peripherals

Diagram below shows the pin configuration of the 89S52, where the function of each pin is written next to it,

and, if it exists, the dual function is written between brackets. Note that the pins that have dual functions can

still be used normally as an input/output pin. Unless the program uses their dual functions, all the 32 I/O pins

of the microcontroller are configured as input/output pins.

LCDs are used in a wide range of applications including computer monitors, televisions, instrument

panels, aircraft cockpit displays, and signage.

They are common in consumer devices such as video players, gaming devices, clocks, watches, calculators,

and telephones, and have replaced cathode ray tube (CRT) displays in most applications.

They are available in a wider range of screen sizes than CRT and plasma displays, and since they do not use

phosphors, they do not suffer image burn-in. LCDs are, however, susceptible to image persistence.

3.3.5 VIBRATION SENSOR

This project can be used as vibration activated sensor. Piezo electric sensor plate can be fixed on table, door,

car, window etc. ..using cello tape or adhesive.

When the sensor vibrate, piezo electric sensor converts mechanical vibrations into electrical variations.

Electrical pulses are undergone amplification by transistor amplification stages. Final transistor drives a

piezo buzzer.

Time delay can be changed by adjusting value of capacitor connected across 220K resistors. To active AC

loads buzzer may be replaced by relay. Load to be controlled can be connected via normally opened contacts

of the relay.

For demonstration a 9V DC battery can be used. For continuous use, alarm may be powered using 9V or

12V adaptor. Simple unregulated supply is enough.

This alarm can be used to protect car and other vehicles. Other application of this project is an earthquake

warning alarm.

3.3.7 POWER SUPPLY

A power supply is a device that supplies electric power to an electrical load.

The term is most commonly applied to electric power converters that convert one form of electrical energy

to another, though it may also refer to devices that convert another form of energy to electrical energy.

A regulated power supply is one that controls the output voltage or current to a specific value; the controlled

value is held nearly constant despite variations in either load current or the voltage supplied by the power

supply's energy source.

DC POWER SUPPLY

An AC powered unregulated power supply usually uses a transformer to convert the voltage from the wall

outlet (mains) to a different, nowadays usually lower, voltage.

If it is used to produce DC, a rectifier is used to convert alternating voltage to a pulsating direct voltage,

followed by a filter, comprising one or more capacitors, resistors, and sometimes inductors, to filter out

(smooth) most of the pulsation.

A small remaining unwanted alternating voltage component at mains or twice mains power frequency ripple

is unavoidably superimposed on the direct output voltage.

For purposes such as charging batteries the ripple is not a problem, and the simplest unregulated mains-

powered DC power supply circuit consists of a transformer driving a single diode in series with a resistor.

AC POWER SUPPLY

An AC power supply typically takes the voltage from a wall outlet (mains supply) and lowers it to the

desired voltage. Some filtering may take.

FULL WAVE RECTIFIER

Another type of circuit that produces the same output waveform as the full wave rectifier circuit above, is

that of the Full Wave Bridge Rectifier.


20

This type of single phase rectifier uses four individual rectifying diodes connected in a closed loop "bridge"

configuration to produce the desired output.

The main advantage of this bridge circuit is that it does not require a special centre tapped transformer,

thereby reducing its size and cost. The single secondary winding is connected to one side of the diode bridge

network and the load to the other side as shown below.

The four diodes labelled D1 to D4 are arranged in "series pairs" with only two diodes conducting current

during each half cycle.

During the positive half cycle of the supply, diodes D1 and D2 conduct in series while diodes D3 and D4 are

reverse biased and the current flows through the load as shown below.

KEIL SOFTWARE

KEIL Micro Vision is an integrated development environment used to create software to be run

on embedded systems (like a microcontroller). It allows for such software to be written either in

assembly or C programming languages and for that software to be simulated on a computer

before being loaded onto the microcontroller. The software used is c programming.

Vision3 is an IDE (Integrated Development Environment) that helps write, compile, and

debug embedded programs. It encapsulates the following components:


22

A project manager.

A make facility.

Tool configuration.

Editor.

A powerful debugger.

To create a new project, simply start micro vision and select Project=>New Project

from the pulldown menus. In the file dialog that appears, a filename and directory was chosen for the

project. It is recommended that a new directory be created for each project.

As several files will be generated. Once the project has been named, the dialog shown in the figure below

will appear, prompting the user to select a target device.

The chip being used is the AT89S52, which is listed under the heading Atmel.

Next, Micro Vision was instructed to generate a HEX file upon program compilation.

A HEX file is a standard file format for storing executable code that is to be loaded onto the microcontroller.

In the Project Workspace pane at the left, rightclick on Target 1 and select Options for Target 1

.Under the Output tab of the resulting options dialog, ensure that both the Create Executable and

Create HEX File options are checked.

Then click OK. Next, a file must be added to the project that will contain the project code.

To do this, expand the Target 1 heading, rightclick on the Source Group 1 folder, and select Add

files Create a new blank file (the file name should end in .c), select it, and click Add. The new file

should now appear in the Project Workspace pane under the Source Group 1 folder.


23

Double-click on the newly created file to open it in the editor. To compile the program, first save all source

files by clicking on the Save All button, and then click on the Rebuild All Target

Files to compile the program as shown in the figure below.

If any errors or warnings occur during compilation, they will be displayed in the output window at the

bottom of the screen.

All errors and warnings will reference the line and column number in which they occur along with a

description of the problem so that they can be easily located .

When the program has been successfully compiled, it can be simulated using the integrated debugger in Kiel

Micro Vision. To start the debugger, select Debug=>Start/Stop

Debug Session from the pulldown menus.

At the left side of the debugger window, a table is displayed containing several key parameters about the

simulated microcontroller, most notably the elapsed time (circled in the figure below). Just above that, there

are several buttons that control code execution.

The Run button will cause the program to run continuously until a breakpoint is reached, whereas the

Step Into button will execute the next line of code and then pause (the current position in the program is

indicated by a yellow arrow to the left of the code).

3.4 CONSTRAINTS

In any event, Trask has not been charged with speeding in relation to the incident, and continued to serve as

the governor's driver.

3.5 SYSTEM RELIABILITY

These devices record both pre- and post-accident data in a storage device and The GPS and GSM module

will send information of latitude and The main features of black box is audio and video recording longitude

of car, date of accident, time of accident, car speed and head to a specified number but not give information

whether or not the driver or passenger was wearing a seatbelt.

In any event, Trask has not been charged with speeding in relation to the incident, and continued to serve as

the governor's driver.

3.6 SAFETY AND SECURITY OF SYSTEM

This system is fitted in car and if accident occurred then all the information of car and location is send to the

emergency centre. In security system if another person start the car then the GSM module will send the

manage to the owner of car.

CHAPTER 4: SYSTEM DESIGN

4.1 SYSTAM ANALISIS

A system analysis is a short, focused study, which aims to answer a number of questions:

Does the system contribute to the overall objective of the organization?

Can the system be implemented using current technology and within given cost and schedule constrains?

Can the system be integrated with system which already in place?

1) OPTIONAL FEASIBILITY:

Operational feasibility measures how well the solution will work in the organization and how well

end-user & management feel about system? Proposed system is helpful for the operator and user. It will

allow them to get the appropriate and adequate information.

On studying the operational feasibility of the project, the following conclusion can be derived:

Developed system for the elevator control system will provide the adequate throughput and all necessary

information to users and operators.

It will provide advantageous and reliable services.

If it can be installed within suitable environment, system will do operations under environment of limited

resources.

Thus, it is operationally feasible to develop the proposed system.

2) TECHNICAL FEASIBILITY:

Technical feasibility tries to answer the following questions to make the project feasible to develop.

The hardware and software tools necessary for building or running the application are easily available or

not?

The compatibility amongst system exists or not?

Are developers aware of these technologies?

What about the alternative of this chosen system?

So, I have found the answer of the above questions, as given below:

Here I have preferred AT89C51 microcontroller .

So, the project is feasible.


26

3) ECONOMIC FEASIBILITY:

Economic feasibility addresses the following issues:

Is the organization having the suitable budget to develop the proposed system?

How much profit can be earned from the system organization?

Would it be cost effective to develop the system or is worthwhile to remain with current system?

I would like to answer for the above questions below:

As development hardware and software with functionally and cost concern

The organization doesnt having the same system, so it is certainly required for them.

The project will be remarkable according to our team has seen as far as older one AFT concerned

So, it is economical feasible to the organization.

4) IMPLEMENTATION FEASIBILITY:

Under the study of implementation feasibility, I have got to draw the finger to the certain issues, like:

Is it possible to install within the given environment?

Will organization management and users support for the installation of the project?

Will proposed system cause any harm to operation of the organization?

Operationally, this system can be installed and it can work according to its functionalities. There would

be very little barriers in implementations, if application will be prepared according to hardware barriers.

The management has already approved this project to be developed and it wont cause any harm to users

operation or day to day activities.

5) PROJECT SCHEDULING:

Project scheduling is an activity that distributes estimated efforts across the plan duration by

allocating the effort of specific software engineering task

Proper scheduling required.

All tasks appear in work.

Efforts and timing are intelligently allocated to each task.

Interdependencies between tasks are properly indicated.

Resources are allocated for the work to be done.


27

Though there are many reasons for completion of project, following are the prominent ones that are

the roots of late completion.

To schedule our project, we followed basic principles of project scheduling.

6) COMPARTMENTALIZATION:

I have divided the project into following task:

Hardware interface

Programming

Testing

7) INTERDEPENDENCY:

Interdependency of each compartmentalized activities were hence found out. Some tasks must occur in

sequence whereas some can occur in parallel.

8) TASK SET:

A task set was defined for the project; task set is a collection or work task, milestones and outcomes

that must be accomplished to complete a particular project.

Hardware divides in main groups as given below:

Concept development

Make a circuit as per that

New application development

Application enhancement

Application maintenance

Testing

Software divides in main groups as given below:

Logic development

Module designing

Module integrating

Testing


28

9) DEFINING ADAPTATION CRITERIA:

Adaptation criteria were used to determine the recommended degree of rigor with which the hardware-

software should be applied on a project.

Criteria for the project:

Size

Number of users

Mission critical

Application longevity

Application requirement

Stable requirement

Maturity of technology used

Performance constrains

Embedded/ non embedded

Re-engineering efforts

10) SELECTION OF PROJECT TASKS:

Since the project belonged to new application development category, I selected the following tasks.

Domain understanding

Analysis of required system

Defining scope and objectives

Finding out the efforts and the time estimation

Preparing the schedule

Finding our resources requirement

Implementation

Testing

From the selection of above tasks, I can elaborate them into pictorial representation so that I can understand

the activities in more understandable manner along with their respected time interval.


29

4.2 SYSTAM ACTVITY

When car is started the audio and video recording is started by a night vision camera which is in a black box,

normally it record front view of the car.

When car is started the GPS and GSM module send a alert message to a car owner or emergency canter that

inform them its car states like longitude of car, date of accident, time of accident, car speed and head to a

specified number.

When the accident is take place, it is detected by a vibration sensor and it send a alert message to a car

owner or emergency canter that inform them its car states like longitude of car, date of accident, time of

accident, car speed and head to a specified number.

CHAPTER 6: SYATEM TESTING

6.1 TEST CASE

First we check the system is fitted in car properly or not.

Then, front camera is fitted and we will check whether camera is working or not. The video captured by

camera is recorded and stored in memory storage.

Now, there is GPS and GSM module. GPS will show the location of the car and GSM module is used to

send message when accident occurred. And it is also used for security system. Suppose a different person

start a car then a message will be sent to the owner of the car.

We have tested the whole system by planning mock accident. In case of accident,the information (Location

and details) of car will be sent to emergency centre.

6.2 TEST PLAN

If accident happened than the ambulance reach their that take long time and dont get proper information

from this system a massage will be send to the emergency centre and easily ambulance can reach there. We

test this system through three different cases which is tested above in test.


55

CHAPTER 7: CONCLUSION AND FATURE PLAN

7.1 CONCLUSION

With this technology, the details of the car like speed, location of the vehicle etc, at a certain given time

can be recorded. This system is easy to implement and reduce dead percentage of people with the

accident occur using the wireless communication technologies.

The driving behaviors that are monitored are ones which influence the likelihood of the driver crashing

(for example, speed) or the severity of the crash (for example, seat belt use). These are proxies for crash

and injury risk, and monitoring a drivers propensity to indulge in such behaviors enables the technology

to calculate a risk rating for that driver. It also, potentially, enables measures to be identified that may

reduce the drivers crash risk.

With the help of GPS located the location of accident area, where accident is occurred and reduce death

percentage of people with providing fast services like ambulance.

7.2 FATURE PLAN

We can enhance the present system to check other parameters like fuel level, tire pressure and working

of headlights before starting the vehicle.

Another useful add-on to the present system could be cameras on front and backsides which keep

recording live images and storing them in memory

We get to learn various aspects of digital electronics. This gives us complete knowledge of designing

microcontroller based system and developing embedded software. This principle can be utilized for

Vigilance, security, scrutiny of various kinds of transportation means Sense Cam: this badge-sized

wearable camera reportedly captures up to 2000 VGA images within a 12-hour day and stores it in a

128Mbyte flash memory. So, most every scribbled note and every promised meeting would be recorded

for to look at later

In the future we can integrate this device with alcohol detector circuit. With the help of this device car

cannot be start when alcohol is detected so that number of accident can be reduce
