Escape system for a sinking car and ultrasonic component thereof

[Category : - Automotive Accessories - Security and alarms]
[Viewed 129 times]

Affected by extreme climates, major disasters caused by storm rain and floods have become the new normal in countries all over the world. Many drivers and passengers died in sudden floods or cars falling into the water.
An escape system for a sinking car and an ultrasonic component thereof are illustrated. In the present disclosure, an ultrasonic signal transmitting unit capable of emitting ultrasonic is installed on the car. When the car falls into the water, based upon an acoustic resistance concept which the ultrasonic propagated in air collides and transmits into the water, a difference between a reflection or transmittance rate of the ultrasonic and a corresponding set value can be calculated, or alternatively, a difference between a reflection time deviation or a reflection distance of the ultrasonic and a corresponding set value can be calculated. Therefore, a warning signal indicating that the car falls into the water can be fast sent, and this makes sure that the rescue opportunity which the car falls into the water can be grasped to decrease the damage or death of the user.
