ARM Cortex M3 Based Collision Detection System

ARM Cortex M3 Based Collision Detection System

Abstract:

This paper explains mainly about how to find out the vehicle location when met with an accident using GPS, ADXL sensor to release Air bag and sending message for aid using GSM. An automobile remote alarm system based on GSM communication network is introduced. The TC35 GSM module and ADXL sensor is combined with the system, vibration sensor and speed sensor are used to achieve short message service (SMS) . The shortcoming of traditional systems including low security and small alarming range is overcome, and the cost of this system is decrease, so it should have good application prospects. Vehicle tracking system is one of the latest topics in embedded systems industry. Where a vehicle can be tracked anywhere on the globe. Here ARM LPC1768 communicates with GPS module and GSM modem. Which would be placed in a moving vehicle. The ARM LPC1768 will poll GPS module in prefixed intervals and sends the vehicle location information like Latitude & Longitude to central station over GSM network. When ever any accident occurs ADXL sensor detects the vibration of the vehicle and sends mechanical force to ARM lpc1768. Using GPS, we will get particular location where accident occurs, then GSM sends message to authorized members & 108.
