Embodiment 1
[0019] Example 1: A car drowning self-rescue system, including a sensor sequence composed of several liquid pressure sensors, a vehicle-mounted water-falling detection ECU device, and an airbag inflation device; The liquid pressure value on the periphery of the vehicle body, the on-board water falling detection ECU device collects the liquid pressure value on the periphery of the vehicle body transmitted by each liquid pressure sensor in real time, when it detects that the collected value of a certain liquid pressure sensor exceeds the limit value, the water falling detection ECU device activates the liquid pressure value The igniter in the airbag inflator corresponding to the pressure sensor causes the airbag to generate nitrogen and inflate.
[0020] The above scheme realizes that when the car falls into the water, the nitrogen gas is expanded by the air bag inflation device, thereby relying on the buoyancy of the nitrogen gas, so that the car will not sink. When the car f...
Embodiment 2
[0024] Example 2: This embodiment has the same technical solution as Embodiment 1. More specifically, the falling water detection ECU device includes a central processing unit, a signal acquisition and processing circuit, and an ignition control circuit. The liquid pressure value signal is transmitted to the processor for comparison with the predetermined value. When the predetermined value is exceeded, the central processor outputs a control signal to the ignition control circuit, and the ignition control circuit activates the igniter in the airbag.
[0025] As a further preference of the technical solution, the water falling detection ECU device also includes a self-power supply circuit and a state prompt circuit, the self power supply circuit uses an external power supply to supply power to the water fall detection ECU device, and the state prompt circuit displays the trigger state of each liquid pressure sensor, This indicates the current flooding condition of the vehicle...
Embodiment 3
[0030] Example 3: It has the same technical solution as that of Embodiment 1 or 2, and more specifically, the liquid pressure sensor is placed in a protective cover all over the water inlet holes. When installing, the pressure sensor is placed in the protective cover covered with small holes, which can not only ensure that the liquid flows into the protective cover for detection, but also prevent false detection caused by external impact. Liquid pressure sensor device.
