The main objective of this project is to design and implement an accident identification system using GSM.
GSM (Global System for Mobile communications: originally from Groupe Spécial Mobile) is the most popular standard for mobile phones in the world. Its promoter, the GSM Association, estimates that 82% of the global mobile market uses the standard. GSM is used by over 3 billion people across more than 212 countries and territories. Its ubiquity makes international roaming very common between mobile phone operators, enabling subscribers to use their phones in many parts of the world. GSM differs from its predecessors in that both signaling and speech channels are digital, and thus is considered a second generation (2G) mobile phone system. This has also meant that data communication was easy to build into the system.
The ubiquity of the GSM standard has been an advantage to both consumers (who benefit from the ability to roam and switch carriers without switching phones) and also to network operators (who can choose equipment from any of the many vendors implementing GSM). GSM also pioneered a low-cost (to the network carrier) alternative to voice calls, the Short message service (SMS, also called "text messaging"), which is now supported on other mobile standards as well.
In this project we propose a novel approach to detect accident based system using a 32 bit controller – ARM cortex.
This project consists of the following blocks – sensors, amplifier, ARM core, GSM and GPS modem.
The vibration sensor senses the the vibration of the in the course of occurrence of an accident. We use an shock sensor to sense the vibration. The distance measurement sensor senses the distance of the vehicle from its neighbor. The output from the sensors are amplified by using an instrumentation amplifier and fed to the ARM core. The controller is programmed using
