Implementation of Panic Button in Mobile Phones

Abstract

Our objective in this paper is to present a feasible solution to send a SoS message in a phase where the phone is switched off. SoS distress signal is an abbreviation for “save our souls” or “save our ship.” But in reality, "save our souls" and "save our ship" are backronyms, and the letters don’t actually stand for anything. Morse code string of three dots, three dashes, and three dots all run together with no spaces or full stops (…---…). Since three dots form the letter "S" and three dashes form an “O” in International Morse code, though, the signal came to be called an “SOS” for the sake of convenience. In the existing System, it deals with send SoS message to the given emergency number when the phone in ON condition by using a SoS app, The major problem arise here is when the device is switched off the SoS message cannot be send, our system become the solution for this problem. In our proposing system there is a secondary battery storage, which only use for the emergency services. The GPS and GSM modules are works within it. Here uses a secondary power source and Adding an separate button to send SoS messages, When the SoS button is pressed the phone starts sending an alert message which contains the current location and the alert SMS to the contact that already registered for this service in our device. Raspberry Pi and Arduino (ATmega 328) are the major components.
