Table of ContentsSystem OperationAnalysis of Recovered DataConclusionIn the last decade, various automobiles have become a part of our daily lives. The rapid increase in the number of vehicles leads to serious problems such as poor driving habits, heavy traffic, unstable vehicle condition, etc. This sometimes leads to fatal accidents causing a large number of victims. This not only involves loss of human lives but also huge financial losses. These incidents cannot be completely eradicated, but can be further reduced with the help of Black Box. How it helps the investigation by reconstructing the event before the accident, which not only helps the investigator to know the real cause but also helps the police in reducing crimes. It is shown how medical aid is provided to passengers who have had an accident in the region. The application of the black box in commercial trucking companies is explained. The main objective of the Black Box is to provide a feasible and useful scenario for public safety. Say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”? Get the original essay According to the World Health Organization (WHO), more than 1.25 million people lose their lives as a result of road traffic accidents. Many people lose their lives because they are left unattended for a long time after an accident. An additional approximately 20 to 25 million people suffer nonfatal injuries, and many become disabled as a result of these injuries. In the past, due to the lack of EDR technology in vehicles, the victim was often considered the aggressor and the actual cause remained undefined. To solve this problem, Black Box is introduced in the automobile industry, which not only helps the accident investigator to know the real cause of the accident but also helps in suggesting measures to save lives. The first Black Box was introduced in 1974 by General Motors in cars equipped with airbags called Sensing and Diagnostic Modules (SDM). It continuously collects and processes the car's accelerations and decelerations. In 1999, General Motors upgraded the SDM to include an event data recorder that tracks the car's speed, engine revolutions per minute (RPM), and whether or not the brake pedal is depressed. The SDM keeps the recording of the previous 5 seconds after the accident and stores it in its on-board memory and, if the airbags are deployed, it records the most recent five seconds which lead to the actual cause of the accident. The European Parliament passed a law requiring every new car built after April 2018 to be equipped with a system called "eCall." It is a sort of black box that automatically contacts the single emergency number 112-Europe in the event of an accident. This will help provide first aid at an early stage to people who have suffered an accident in remote areas. The data stored in the Black Box should only be accessed by an authorized person, so to keep it safe, the data stored on the Secure Digital (SD) card is encrypted. The change in physical quantity is observed by the sensor, causing the output to be sent. following the connected controller. The controller will read the sensor output. Data is stored on the SD card. To prevent data tampering, an encryption algorithm is used and the same data can be accessed by applying a decryption algorithm. The black box of the car is equipped withdifferent types of sensing components that are activated immediately with an earlier possibility of problems about to occur. It is even triggered due to a change in characteristics or conditions such as temperature, speed, pressure or the application of a sudden brake. The representation of the modules and components to be used is done in blocks. It consists of various sensors such as brake, seat belt, airbag deployment, accelerometer, ultrasound, pressure, temperature, light and global positioning satellite (GPS). Various sensors can be connected depending on the sensor connection capability of the processor. All these sensors are connected to the CAN module and controller using the CAN bus. At the end event data logger is used to store the data, it consists of a module to keep the data in a specified format. The microcontroller is the main component of the system. It regulates all the sensors connected to it. Depending on the requirements, different types of processors can be used in the system. The ARM7 (machine Advance RISC (Reduced Instruction Set Computer)) processor is a member of the ARM microcontroller family with a general-purpose 32-bit processor. It offers high performance with low power consumption. Compared to ARM7 with many processors, each processor takes several cycles for instruction execution. Control Area Network: It is a single integrated circuit and controller based on a microchip technology device. The International Organization for Standardization (ISO) has defined CAN as a communication bus primarily designed for the automobile industry to replace the complex wiring harness with a two-wire bus. CAN have high immunity at the electrical interface and it can diagnose and repair the data error by itself. The CAN communication protocol, ISO-11898:2003, shows how information is transmitted between devices on a network and conforms to the Open System Interconnection (OSI) module which is defined according to layers. The physical layer of the model is used to define the actual communication between devices connected by physical media. ISO-11898:2003, the 11-bit identifier standard, provides signaling rates from 125 kbps to 1 Mbps. This was later changed to the 29-bit "extended" identifier. The standard 11-bit identifier field provides 211, or 2,048 different message identifiers, while the extended 29-bit identifier provides 229, or 537 million identifiers. Electronic Sensing Components: Electronic sensing components are considered the most important part of the system. Here, the sensors are our electronic sensing components. The sensors to be used are explained below: Break: The brake sensor is also called the brake pedal position sensor. It monitors the movement of the brake pedal so it can directly activate the brake, brake lights and turn off cruise control if it is active at the time. Seat belt: to check whether the driver has worn the seat belt or not. the push button is used. Reed switch sensor is used to check the condition of the seat belt at the time of an accident or any incident. Air Bag: Airbag deployment is triggered by crash sensors (also called impact sensors). It detects the frontal impact of the collision and triggers the control unit so that it deploys the airbag to cushion the passenger. Mainly two types of sensors are used for airbag deployment: mass type sensor and roller type sensor. Accelerometer: it is a.
