Automatic Accident Alert and Safety System using Embedded GSM Interface

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.

Smart Car Prevention and Security

“…Thus we can bring down the alarming rate of road accidents. Because of the flexibility of the embedded system, this system is compatible to any type of vehicle and is affordable to common man [9]. Thus, the proposed system can serve the humanity by a great deal as human life is valuable.…”

Human Lives Matter: Intelligent Transport System for Protecting Human Lives

“…This system is not capable of alerting the relevant person if any accident is detected. This may lead to serious problems [5,6,7]. Advantages: (i)Reduce the number of road accidents (ii)Without wearing helmet rider can't start the vehicle (iii)Automatic wiper mechanism is present in this system Disadvantages: (i)Fatalities may happen (ii)Unsecured system (iii)Automatic engine control is not possible.…”
