ARM 7 Based Automatic Accident Alert and Safety System using GPS & GSM Interface.

  • The project ideas is to have a secured Accident alert and safety system.
  • Project uses the Arm 7 Micro-controller along with GPS for location tracking and GSM Modules for sending Alert SMS.
  • Accelerometer Sensor is used

Introduction

We come across accidents every where. Hence it becomes utmost important for every one to use accident safety systems equipped in thier vehicles for the safe journey.

We can observe that in the case of an accident the vehicle would be suddenly decelerated in such a condition, So by using An accelerometer sensor continuously to monitor the acceleration of the vehicle can detect the decelerations. And if the decelerations are greater than threshold value then the same data is send to the microcontroller. We should program the Micro-controller to compare these shared results from the sensor with the threshold set value and immediately warning messages should be sent to the nearest police station and relatives numbers from already available data from the database.

We can make sure that along With this message the micro-controller should also transmit the GPS coordinates of the vehicle which it continuously obtains from the GPS module. Thus the system can aid in the search and rescue of vehicles that have met with an accident.

Components Required:

Below components can be used to implement the project.

  1. ARM 7 Micro Controller
  2. Regulated power supply unit
  3. Buzzer
  4. GPS Module
  5. GSM Module - SIM 900A
  6. Accelerometer Sensor
  7. LCD Display

Project Description:

The system discussed here 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 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 sensor 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 warning messages to present numbers in its database. 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.

Applications of the project

  • With this system, an Embedded System is designed which can be most useful for Accidents.
  • Itís a low cost, Power efficient system by which the action time can be minimized and exact location of an accident can also be defined with GPS service and also the information regarding accident can be sent to particular contact numbers e.g., Police stations, Doctors etc.
  • Because of the flexibility of embedded system, this system is very much compatible to any kind of vehicles.
