Automatic Accident Alert and Safety System using Embedded GSM Interface Kajal Nandaniya I&C Department DDIT, Nadiad Viraj Choksi Project Scientist BISAG, Ghandhinagar Ashish Patel Assistant professor I&C Department, DDIT, Nadiad M B Potdar. Ph.D Project Director BISAG, Gandhinagar ABSTRACT The system envisioned is an automatic collision detection and warning system relying on GPS module and a GSM modem. The vehicle to be safeguarded is to be fitted with the system sturdily ensuring good mechanical coupling with the entire chassis. In the case of an accident the system detects it using the fact that the vehicle would be suddenly decelerated in such a condition. An accelerometer continuously monitors the acceleration of the vehicle and will detect decelerations greater than threshold value and send the data to the microcontroller via an ADC. The controller compares this with the threshold set value and immediately sends an SOS message to preset numbers. With this message the controller also transmits the GPS coordinates of the vehicle which it continuously obtains from the GPS module. This system will highly aid the search and rescue of vehicles that have met with an accident. Keywords Keywords - Embedded, Microcontroller, Accelerometer sensor, GSM, GPS 1. INTRODUCTION Now a day the vehicle accident rate has been increasing day by day, when compared to previous decade the theft rate has been increased by 54% in order to avoid this vehicle accident this system provide security to the vehicles. Main aim of this work is to provide security to the vehicle in very reasonable cost so in this work the basic microcontroller AT89S52 is used for cost effective and also for easy understanding. In this work C programming is used for better accuracy and GPS and GSM modules which helps use to trace the vehicle anywhere on the globe. Here, GPS, user segment and control segment are used to trace the vehicle perfectly and here GSM is used to send the exact location of the vehicle and send alert or relax message to this remote device (mobile phone) [1]. To detect the accident, accelerometer sensor used. So, when accident happens, this sensor will be active. And the information sends to microcontroller. At the same time, GPS and GSM modem will also active which are interfaced to the same microcontroller. Through GPS the exact latitude and longitude of the accident location is obtained. And through GSM modem the same data send to the contacts which are stored in the database. So with this system, information is send to the Police Stations, friends etc. and also decrease the total action time and save the lives in emergencies. 2. SYSTEM BLOCK DIAGRAM Fig 1: System Block Diagram Here in this system, AT89S52 is used as main microcontroller. This system is made for the Accident alert system. Here, the whole system is to be implemented in the vehicle itself. So, when the accident happens, due to vibrations, the accelerometer sensor gets active. It measures the certain intensity of shocks and vibrations. So it is detected to microcontroller through ADC0804. Here ADC0804 required, which is interface between MMA7361L and microcontroller AT89S52 because output of the accelerometer sensor is analog and to interface with microcontroller, it is to be converted in to the digital. At the same time, when accident happens, with GPS the latitude and longitude of that particular location is obtained. And with that the exact location of the accident site is determined. And here, GSM modem SIM300 is interfaced with microcontroller. So that, when accident happens, the SMS will be sending automatically to the particular numbers which would be entered in the database. So with this system rescue operation can be made faster. |
