| Summary: | 碩士 === 中原大學 === 電子工程研究所 === 107 === In the government promotion information, people are often educated that when their cars fall into water accidentally, the cars may sink easily due to the weight of the engines at the car heads. When this thing happens, people in the car should keep calm, unlock the seat belt in the very first moment and open a car window as soon as possible, so that they can climb out of the car from the window before the car sinks. However, if the car has already sunk in the water completely, the car doors will not be opened easily due to the hydraulic pressure difference between the inner part and the outer part of the car, and the automatic windows will not be activated as water has entered into the car. At this moment, the car will sink completely in about 60 seconds, and the trapped persons should find a sharp object in the car in time to strike the windshields that they may have a chance of survival. On the contrary, if not being able to take the chance of escape in 60 seconds, the trapped persons will have a very little chance of survival.
The technology relates to an escape system for a sinking car and an ultrasonic component thereof; and more particularly to an escape system for a sinking car with an ultrasonic component thereof that can facilitate receiving and transmitting the car sinking signal quickly, so as to take opportunities of rescue.
