Abstract: Vehicle automatic alarming and navigation system is the result of
solving the problem that the property loss and casualty due to untimely rescue in a
traffic accident when general communication means can’t work normally. The system
invents a kind of automatic alarming and navigation equipment which by using GPS
receiver module, RF receive and transmit module and embedded microcontroller.
With the help of this equipment, vehicles nearby can find the place of the traffic
accident quickly, rescue the wounded in time and in a certain extent even save their
lives.
