Accident Detection And Alerting System

ACCIDENT DETECTION AND ALERTING carcrashesin2015[2].ReportsfromAutocarproexpress, that onregular routine street mishaps have taken 405 lives and harmed 1020 individuals in 2017 [3]. On yearlypremise, 1.5 lakh individuals are seen to have passed on in mishaps by a study directed by ince anticipation of mishaps is not in our grasp, we expect to give crisis benefits as quickly as befollowedandsenttocrisiscontactsinacouple of moments seconds so that the closest medical clinic can arrive at the spot as quickly astimepermits and spare the life of the individual. On the off chance that the mishap is not extreme, we give akey which lets the driver end the framework, with the goal that the message has not been sentconsequently helping in sparing the hour of rescue vehicle. The message is sent through GSMMODULE and the area is followed by GPS module. The mishap is recognized with the assistance ofaccelerometer sensor. The accelerometer is utilized as an accident or rollover identifier of the vehicleduring and after an accident. With signals from an accelerometer, a seriousness of the mishap can beperceived. This venture gives answer for some serious issues. Vehicle following framework furnishessecurity to vehicles and furthermore with the assistance of GPS an individual can follow his vehicle anddiscover the vehicle development and its past exercises. Mishap ready framework primarily means tospare the valuable existence to the individuals. The gear is little and can be fit into any vehicleeffectively. Taken vehicle recuperation will be simpler since we are following the vehicle. A basicframework can be utilized for different purposes.The Accident Detection and Alert System using Arduino is very sufficient and worthy to ing due to increase in number of vehicles as a result every year the number of death is increasing.The Accident Detection and Alert System using Arduino prevent the uncertain death after accidentbecause this system send the message alert to the hospital or police station. The message alert includelongitude, latitude (location of accident), in the form of google maplink.In our previous tutorials, we have learned about How to interface GPS module with Computer,how to build a Arduino GPS Clock and how to Track vehicle using GSM and GPS. Here in this project,

ACCIDENT DETECTION AND ALERTING SYSTEMwe are going to build a Arduino based vehicle accident alert system using GPS, GSM andaccelerometer. Accelerometer detects the sudden change in the axes of vehicle and GSM modules endthe alert message on your Mobile Phone with the location of the accident. Location of accident is sent inthe form of Google Map link, derived from the latitude and longitude from GPS module. The Messagealso contains the speed of vehicle in knots. See the Demo Video at the end. This Vehicle Accident alertproject can also be used as a Tracking System and much more, by just making few changes in hardwareand software.

ACCIDENT DETECTION AND ALERTING SYSTEMCHAPTER3LITERATURE SURVEYFrom the past event and the existing approach the below Drawback are been noted:1. Manual system is adopted.2. Tracking of accident is a crucial process in the system.3. Required medical attention cannot be given to the needed person.4. Life loss and Property loss were not stopped in large scale.Considering all the drawbacks into account we have formulated a proposed system which covers allthe above mentioned drawbacks.1. Automated system is used once the accident occurs.2. This system gives the Latitude and Longitude of the system accident occurred area without any delay.3.More Human life can be saved using this automated system.To protect the vehicle and tracking so many advanced technologies are available now a days. In oldendays the information of accident can be transferred, but the place of accident spot cannot be identified.In any vehicle airbags are designed, air bags are used for security and safety travels [2]. The air bagsystem was introduced in the year of1968. TPMS is system designed to control the pressure inside the pneumatic tires on vehicles thatprovides different operating conditions such as a lower tire pressure is desired in order to maximizetraction, maneuvering through challenging terrain, pulling a heavy load out of an incline at slow speeds,crawling out of soft dirt. The pressure ranges from 15 to 45PSI.

ACCIDENT DETECTION AND ALERTING SYSTEM Many other systems have been proposed to deduce the accident. The existing system deals withtwo sensors where MEMS sensor is used to detect the angle and vibration sensor is used for detectionthe change in the vehicle. The other existing system uses IOT and cloud computing system. Where the vehicle detection iddone through SVM (support vehicle machine) that is developed by Ant Colony Algorithm (ACA). HereIOT will monitor the vehicles using magneto resistive sensors. The main aim of this project is todifferentiate the accidents which took place in traffic and at no traffic place. Existing system also provides the location of the accident using at mega 328 Micro controllerand RF transmitter and receiver. The information is sent to the saved mobile numbers [3].This vehicle tracking system takes input from GPS and sends it through the GSM module todesired mobile/laptop using mobile communication. Vehicle Tracking System is one of the biggesttechnological advancements to track the activities of the vehicle. The security system uses GlobalPositioning System GPS, to find the location of the monitored or tracked vehicle and then uses satelliteor radio systems to send to send the coordinates and the location data to the monitoring centre. Atmonitoring centre various software‟s are used to plot the Vehicle on a map. In this way the Vehicleowners are able to track their vehicle on a real-time basis. Due to real-time tracking facility, vehicletracking systems are becoming increasingly popular among owners of expensive vehicles.

ACCIDENT DETECTION AND ALERTING SYSTEMCHAPTER 4EXISTING AND PROPOSED SYSTEMExisting system:Presently a lot of methodologies are available in vehicles that allow vehicle protection andtracking. Airbags are one of the most mandatory elements in vehicles. Front airbags have been standardon all new cars since 1998 and light trucks since 1999. Seat belts are also available in four wheelers.tirepressure monitoring system (TPMS) is an electronic system designed to monitor the air pressure insidethe pneumatic tires on various types of vehicles. TPMS report real time tire-pressure information to thedriver of the vehicle, either via a gauge, a pictogram display, or a simple low pressure warning light. Ananti-lock braking system or anti-skid braking system (ABS) is an automobile safety system that allowsthe wheels on a motor vehicle to maintain tractive contact with the road surface according to driverinputs while braking, preventing the wheels from locking up (ceasing rotation) and avoidinguncontrolled skidding. Traction control and electronic stability control go hand in hand and is designedto prevent loss of traction of driven road wheels. The latest implementation techniques move along thelines of providing help to the driver even if he is trapped in a remote location unable torespond.Proposed system:This system is very efficient and hence worthy to be implemented. Accident detection andmessaging system can be fitted in vehicle (Ambulance, Police or to the communication device of thenear and dear) and they are informed about any such untoward incident at the go. Accident detection andmessaging system is executions impalas the system makes use of GSM & GPS technologies. GPS isused for taking the coordinate of the site of the accident while GSM is used for sending the message tophone. To make this process all the control is made using Arduino whereas LCD is used to display theaccident.

ACCIDENT DETECTION AND ALERTING SYSTEMIntroduction to the Arduino BoardThe Arduino is a family of microcontroller boards to simplify electronic design, prototyping andexperimenting for artists, hackers, hobbyists, butal so many professionals. People use it as brains fortheir robots, to build new digital music instruments, or to build a system that lets your house plants tweetyou when they‟re dry. Arduinos (we use the standard Arduino Uno) are built around an AT megamicrocontroller essentially a complete computer with CPU, RAM, Flash memory, and input/output pins,all on a single chip.Unlike, say, a Raspberry Pi, it‟s designed to attach all kinds of sensors, LEDs, small motors youprogramitinasimplelanguage(C/C ingyourcompiledcodetotheboard.Onceprogrammed, the Arduino can run with the USB link back to your computer, or stand-alone without it nokeyboard or screen needed, justpower.

ACCIDENT DETECTION AND ALERTING SYSTEMFig.5.2: Structure of Arduino BoardFig.5.3: Arduino BoardLooking at the board from the top down, this is an outline of what you will see (parts of the boardyou might interact with in the course of normal use are highlighted).Starting clockwise from the top centre: Analog Reference pin(orange) Digital Ground (lightgreen) Digital Pins 2-13(green)

ACCIDENT DETECTION AND ALERTING SYSTEM Digital Pins 0-1/Serial In/Out - TX/RX (dark green) - These pins cannot be used for digital i/o(Digital Read and Digital Write) if you are also using serial communication (e.g. Serial.Begin) Reset Button - S1 (darkblue) In-circuit Serial Programmer(blue-green) Analog In Pins 0-5 (lightblue) Power and Ground Pins (power: orange, grounds: light orange) External Power Supply In (9-12VDC) - X1(pink) Toggles External Power and USB Power (place jumper on two pins closest to desired supply) SV1(purple) USB (used for uploading sketches to the board and for serial communication between theboardand the computer; can be used to power the board)(yellow)Digital PinsIn addition to the specific functions listed below, the digital pins on an Arduino board can be usedfor general purpose input and output via the pin Mode(),Digital Read(),and Digital Write()commands.Each pin has an internal pull-up resistor which can be turned on and off using digital Write() (w/ avalue of HIGH or LOW, respectively) when the pin is configured as an input. The maximum currentper pin is 40mA. Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. On theArduino Diecimila, these pins are connected to the corresponding pins of the FTDI USB-to-TTLSerial chip. On the Arduino BT, they are connected to the corresponding pins of theWT11Bluetooth module. On the Arduino Mini and Lily Pad Arduino, they are intended for usewith an external TTL serial module (e.g. the Mini-USBAdapter). ExternalInterrupts:2and3. These pins can be configured to trigger an interruptional value,arising or falling edge, or a change in value. See the attach Interrupt()function fordetails. PWM: 3, 5, 6, 9, 10, and 11 Provide 8-bit PWM output with the analog Write()function. Onboards with an ATmega8, PWM output is available only on pins 9, 10, and11. BT Reset: 7.(Arduino BT-only) Connected to the reset line of the Bluetooth module. ortSPIcommunication,which,although provided by the underlying hardware, is not currently included in the Arduinolanguage. LED: 13. On the Diecimila and Lily Pad, there is a built-in LED connected to digitalpin13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.

ACCIDENT DETECTION AND ALERTING SYSTEMAnalog PinsIn addition to the specific functions listed below, the analog input pins support 10-bit analogto-digital conversion (ADC) using the Analog Read()function. Most of the analog inputs can also beused as digital pins: analog input 0 as digital pin 14 through analog input 5 as digital pin 19. Analoginputs 6 and 7 (present on the Mini and BT) cannot be used as digital pins.Power Pins: VIN (sometimes labeled "9V"): The input voltage to the Arduino board when it's using anexternal power source (as opposed to 5 volts from the USB connection or other regulatedpower source). You can supply voltage through this pin, or, if supplying voltage via thepowerjack, access it through this pin. Also note that the Lily Pad has no VIN pin and accepts only aregulated input.5V: The regulated power supply used to power the microcontroller and othercomponents on the board. This can come either from VIN via an on-board regulator, or besupplied by USB or another regulated 5Vsupply. 3V3 (Diecimila -only) :A 3.3 volt supply generated by the on-board FTDIchip. GND: Groundpins.Other Pins AREF: Reference voltage for the analog inputs. Used with analog reference().Reset: (Diecimila-only) Bring this line LOW to reset the microcontroller. Typically used to add are setbutton to shields which block the one on the board.Power supply:In mains-supplied electronic systems the AC input voltage must be converted into a DC voltagewith the right value and degree of stabilization. In these basic configurations the peak voltage acrossthe load is equal to the peak value of the AC voltage supplied by the transformer‟s secondarywinding. For most applications the output ripple produced by these circuits is too high. However, forsome applications - driving small motors or lamps, for example - they are satisfactory. If a filtercapacitor is added after the rectifier diodes the output voltage waveform is improved considerably.The section b- c is a straight line. During this time it is the filter capacitor that supplies theloadcurrent.

ACCIDENT DETECTION AND ALERTING SYSTEMThe slope of this line increases as the current increases, bringing point c lower. Consequently thediode conduction time (c-d) increases, increasing ripple. With zero load current the DC voltage.Figureshowshowtoobtainpositiveandnegative outputsreferred to a common ground. In particular they are helpful in determining the voltage ripple for agiven load current and filter capacitor value. The value of the voltage ripple obtained is oportionaltothefiltercapacitorvalue.Theperformance of asupply commonly used in consumer applications – in audio ircuitsdescribedaboveisinsufficientandastabilizer circuitis needed. This circuit is often used as a reference voltage to apply to the base of a transistor of to theinput of an op amp to obtain higher output current. The simplest example of a series regulator isshown in Figure. In this circuit the transistor is connected as a voltage follower and the output voltageis about 600 - 700mV lower than the zener voltage.The resistor R must be dimensioned so that the zener is correctly biased and that sufficient basecurrent is supplied to the base of Q1. For high load currents the base current of Q1 is no longernegligible. To avoid that the current in the zener drops to the point where effective regulation is notpossible a Darlington may be used in place of the transistor. When better performance is required theop amp circuit shown in Figure is recommended. In this circuit the output voltage is equal to thereference voltage applied to the input of the op amp. With a suitable output buffer higher currents canbe obtained. The output voltage of the Figure 14 circuit can be varied by adding a variable divider inparallel with the zener diode and with its wiper connected to the op amp‟s input.The design of stabilized supplies has been simplified dramatically by the introduction of voltageregulator ICs such as the L78xx and L79xx - three-terminal series regulators which provide a verystable output and include current limiter and thermal protection functions. Regulated power supply isprovidingregulateddcpoweranditconverts220vac supply into regulated dc power of 5v, 9v, 12v, 15v etc. Regulated power supply consists of stepdown transformer, bridge rectifier which is combination of 4 diodes connected in bridge shape.Bridge rectifier has the maximum efficiency and it is best than other rectifiers that‟s why we preferit.

ACCIDENT DETECTION AND ALERTING SYSTEMThis rectifier converts ac into pulsating dc. After rectifier filter circuit is employed, usually capacitorin parallel is used as filter or we can use number of capacitors in parallel and number of inductors inseries. All these filters are low pass filters as we required dc at the o/p. Then after capacitor voltageregulator is used for observing the pure dc o/p. We can use various voltage regulators for obtainingpure dc o/p but we prefer 78xx series voltage regulators as they are simpler, cheaper and easier thanothers.Fig. 5.4: Circuit diagram of regulated power supply section(1)AC Input: This is the input supply from the public utility where the device will be energized. Itis also supplied directly to the relay contacts in the device which connects the load to thesupplywhen the supply is within 200V – 240Vrange.(2)Step down transformer: It steps down the AC supply into 5v on the secondary side. It istherefore a 230/5 v transformer. Any change in the primary reflects in the secondary of thetransformer. So any fluctuations in the input are also reflected as a fluctuation in theoutput.(3)Rectifier: A centre tapped transformer, with four diodes for full wave rectification is used toconvert the ac voltage to a pulsating dc voltage followed by a filter, compr
