Lokesh kumar(Ch.en.u4ece20025) N. kranthi kumar(Ch.en.u4ece20029) G. bhuvan(Ch.en.u4ece20011) SUBJECT: 19ECE214 ABSTRACT Accident identification and alerting project is an existing project. The previous proposed systems are aurdino based consist of vibration sensor and gps and gsm modem. Arduino is the heart of the system which helps in transferring the message to different devices in the system. Vibration sensor will be activated when the accident occurs and the information is transferred to the registered number through GSM module. Using GPS the location can be sent through tracking system to cover the geographical coordinates over the area. The accident can be detected by a vibration sensor which is used as major module in the system. The problem with the proposed system is when ever vehicle fell into some larger path holes vibration sensor get activated and sending some false information to the registered person number that accident had been occurred. So, now we are going to use MEME sensors which predict the accident more accurately than these vibration sensors. To detect the crash more accurately MEME sensors are used with an advanced electronic control unit capacitance based method and the server of the crash is easily determined ECU also take input from the wheel speed sensors and gyroscopes and brake pressure sensors and seat occupancy sensors. INTRODUCTION The development of the transportation system has become the driving force for human beings to have the highest civilization on Earth. Cars are very important in our daily life. We use it to go to work, connect with friends and family, and deliver goods. But it can also cause us problems and kill us in accidents. Speed is one of the most important and important risk factors in driving. This not only affects the severity of the accident, but also increases the risk of the accident. Although various governments and non-governmental organizations around the world are making great efforts through various programs to prevent reckless driving, accidents still occur frequently. However, many lives could have been saved if emergency services had received information about the crash in time. A study by Virtanen et al. It shows that 4.6% of accident deaths can only be prevented if timely emergency services can be provided at the scene of an accident. Therefore, effective automatic accident detection, which automatically informs emergency services along with the location of the accident. WORKING OF PROJECT: • Arduino is Major control unit to communicate between devices when an accident occurs which helps in transferring message to different devices in the system • GPS module will find the location of the vehicle and the information is fetched by the receiver through the coordinates • GSM modem will help to send sms whom ever registered their number • The accelerometer and gyroscope detect the accident occurrence • The vibration sensor is also used to detect the accident by producing voltage from the impact of vehicle movements BLOCK DIAGRAM: WORKING OF GSM The GSM SIM900 module is preferred to enable communication between GPS, GSM and dedicated mobile numbers. The name SIM900 indicates tri-band operation in the frequency range from 900 MHz to 1900 MHz, such as EGSM900 MHz, PCS 1900 MHz and DSC 100 MHz. The receive pin of the GSM module and the transmit pin of the GPS module are used for communication between modules. and cell phone. Working of gps To determine your position on Earth, everything is split into some coordinates, and you can easily fix your position with a module called a GPS module. A GPS SIM28ML is used here. This GPS module locates the vehicle and receives the information received by the GPS receiver through the coordinates, the received data is first sent to the Arduino, and the information is sent to the stored contacts through the GSM module. The frequency operates in the 1575.42 MHz band and the output of the GPS module is in NMEA format with real-time data such as location. Working of aurdino The Arduino UNO is a popular open source microcontroller board based on the ATmega328P microcontroller and developed by Arduino.cc. Arduino is the main control device that detects or warns you in the event of an accident. It collects data from vibration sensors, GPRS and GSM modules and displays the output as a display system or message. Vibration sensors play an important role here. This vibration sensor receives vehicle vibrations and acts as an accident detection module. The Arduino collects information from all other modules and sends messages to the receiver via the GSM module. Working of gyroscope A gyroscope is a device mounted on a base such that its axis rotates freely in one or more directions so that a rotating disk or wheel maintains its orientation regardless of movement of the base. However, the direction changes to another in response to an external torque. \ MEMS sensor working principle : whenever the tilt is appled to the MEMS answer then a balanced mass makes a difference within the electric potential. This can be measured like a change within capacitance then that signal can be changed to create a stable output signal in digital, 4-20mA or VDC. These sensors are fine solution to some applications which do not demand the maximum accuracy like industrial automation position control role and pitch measurement and platform leveling. Types of memes The common types of Memes sensors are obtainable with in the are: Memes accelerometer Memes gyroscopes Memes pressure sensors,Memes magnetic field sensors Simulation done using proteus: Note: since mems sensor is not available in proteus we procceded with the vibration sensor The below simulation is designing using aurdino for for this we are going to add pressure sensor to achieve our objective In the above diagram we are not getting the hex.file path at output of aurdino programming to keep in the proteus simulation we are working on it . Once it is resolved we have to attach the pressure sensor to our simulation and have to do some coding changes along with it to run our project. Error we are in proteus simulation. Conclusion The accident event detection system has been developed. The proposed system is for incident notification and detection. It reads the exact latitude and longitude of the vehicle where the accident occurred and sends it to the nearest ambulance. Arduino helps pass messages to other devices in the system. An accelerometer is used to monitor the direction in which the collision occurred, and a gyroscope is used to detect if the vehicle is overturning. The information is sent to the registered number via the GSM module. GPS allows you to include geographic coordinates for each region by sending your location through a tracking system. Contribution The proposed system contributes to the reduction of deaths from accidents. Accidents that have occurred are detected using the proposed methodology. You can also use the GPS module to pinpoint the scene of the accident and use the GSM module to send a warning message to emergency medical services so you can reach the scene on time, saving people life This feature can help reduce the mortality rate from accidents.
