BLACKBOX FOR AUTOMOBILES
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryWe aim to design a blackbox for automobiles which will record the parameters of vehicle, access its location and deliver sms in case of any emergency and also generate error code. this will bge achieved by using different components like OBD-II scanner(bluetooth) , GPS/ GSM module and microcontroller. In this project we will design a BLACK BOX to create a safe environment for drivers/passengers with its real time car tracking and help people to get quick aid in accidental emergencies and justice to the victims after tragic happening. In this black box, we will collect data from ECU of the vehicle using the OBD-II connector which will be interfaced with a microcontroller via Bluetooth. The system will utilize GPS to obtain a
vehicle's coordinate and transmit it using GSM modem to the predefined phone numbers. We will also detect the alcohol levels in drivers’ breath and presence of CO gas so that when it breaches the safety limits, the
buzzer turns on and notify by sending the SMS using GSM/GPS module. Some of ideas for future development in the domain of engineering are modification in microcontroller, link with cloud, addition of sensors, and reduce the size of Black Box. We also would be providing a port which
can access data our black box and incorporate it in the vast field of Fleet Management
Our main objectives are as follows:
Crash Response/investigation
• Automatic detection of impact and enhancing the ability to analyze accidents
• Emergency Response using GPS/GSM modules
Vehicle management
• Logging vehicle data i.e., diagnosing vehicle through error codes,speed
and fuel logging.
• Keeping a record of locations vehicle travelled to.
Anti – Theft Measure
• Real Time Car Tracking
• Emergency alert SOS
Data Storage and Communication
• Data storage at time of impact
The working of our black box is based upon two major parts: a) Data Collection from the ECU using OBDII connector interfaced with our microcontroller
b) GPS/GSM modules interfacing with Microcontroller for logging positional data onto the memory unit and transmitting it to mobile devices using SMS.
The ECU holds all the data of the sensors present in a vehicle. We linked OBDII connecter to the DLC port of the vehicle in order to access the data from ECU. We need to transfer the ECU’s data to our microcontroller. In order to do that we used a Bluetooth module with our microcontroller and transferred our ECU’s data from OBDII connector to our microcontroller using Bluetooth.
Tracking and Transmission:
We then need to access the data from the GSM/GPS modules and the external sensors we attached to our vehicle. The modems of GSM and GPS module are attached to the microcontroller's transmitter and receiver pins, respectively. The GPS module continuously sends longitude and latitude data to the microcontroller. If the vehicle suddenly decelerates and the deceleration is greater than the threshold value, the microcontroller detects it and retrieves longitude and latitude information and the SMS will be sent to the list of contacts which are predefined into list of contacts which are saved in database of system
Emergency Response:
There are two types of scenarios.
1. SOS button:
In case a user feels they are in a threatening situation, if the person presses the emergency button, it sends a signal which is directly fed to the microcontroller. The exact latitude and longitude of the accident site are determined using GPS. The same information (longitude and latitude) is sent to the contacts recorded in the database through GSM modem.
2. Transmission of Data
An accident is detected by an accelerometer sensor which measures the certain intensity of shocks and vibrations. As vibration occur at the time of accident, this sensor measures the G-force experience by the car. The accelerometer is supplied with 3.6 V by dropping the regulator voltage with two forward biased 1N4007 diode and so the accelerometer is activated at the time of accident due to the occurrence of vibrations.As the output of the accelerometer sensor is analog and microcontroller takes an input in form of digital, so the ADC of the controller is utilized to convert the analog input to digitized form. GPS and GSM module will be activated which they are interfaced by the micro-controller in response to this input signal.
Benefits of the ProjectVehicle mishaps are one of the leading causes of deaths. More than a million people lose their lives to car accidents and we are not able to find out the reasons of accidents. Black box is a device which allow us to find the major problems in our vehicle. Black box monitoring technology helps us to prevent theft and enables the tracking of automobiles. By using this device, it is easy to keep track how vehicle is being used. We can also enhance the safety of passengers and drivers by monitoring vehicle performance.
Following are the best advantages and impact of having black box in our vehicle:
1. Accidental alert system: If we are involved in an accident it will help to keep in touch with emergency aid and with family
2. Stolen car Alert: If your vehicle got stolen than this black box is very useful to find the location of car using the GPS/GSM module.
3. Help proving your Innocence in Accident: We know that this black box includes sensitive and private information as it keeps all the happening recorded in case of accident and help in making good decision
4. Insurance companies: It is helpful for insurance companies for investigating the customer merits if required and also useful to provide justice to the victims after tragic happening.
