Exploration and research of vehicle SOS system based on wireless technology

This paper use current relatively mature SCM technology, apply current advanced MCU chip as the core, follow GSM07.05 protocol specification to develop hardware platform. The system can automatically send a customized message to a designated number when it meets trigger conditions. With this matching upper machine system as a rescue center platform, it need to timely accurate receive “accident” the scene of an emergency signal for help (SOS) and at the same time it make the corresponding action. This can effectively reduce the extent of casualties caused by the accident, so that the parties can receive timely rescue incidents. It has certain social value and economic value.
