Portable drowning-preventing intelligent lifesaving system

Abstract

The invention discloses a portable drowning-preventing intelligent lifesaving system which comprises a control device, a posture sensing device, a lifesaving air bag and a triggering device, wherein the control device comprises a microprocessor; the posture sensing device comprises a pressure sensor, a six-axis MEMS accelerometer, a gyroscope and a heart rate sensor. The triggering device comprises a valve body, a gas cylinder, a firing pin, a gunpowder box filled with gunpowder and an ignition coil; the microprocessor can control the end, located in the gunpowder box, of the ignition coil togenerate sparks, gunpowder in the gunpowder box is detonated, explosive shock waves can push the firing pin to move downwards, and the sharp pin part punctures the sealing cover so that liquid carbondioxide in the gas cylinder is gasified and inflated into the lifesaving airbag through the gas outlet. The system has the advantages that the size is small, the weight is light, and the air bag can be inflated and opened quickly and automatically.

Description

technical field [0001] The invention relates to the technical field of drowning lifesaving, in particular to a portable intelligent lifesaving system for preventing drowning, which is suitable for swimming, diving, underwater work and other occasions. Background technique [0002] At present, in order to prevent drowning in water, some devices are commonly used, such as water buoys, life jackets, power inflatable lifesaving devices or chemical reaction inflatable lifesaving devices, etc. However, these lifesaving devices have some disadvantages, such as large weight and large volume. , inconvenient to carry, etc., which makes people wearing such devices affect the comfort of swimmers, let alone diving and other underwater operations, and some life-saving systems, simple pressure and three-axis sensors enable the equipment to automatically monitor the drowning state and then Trigger rescue measures, but its trigger mechanism is too complicated and often requires a large volum...

Problems solved by technology

[0002] At present, in order to prevent drowning in water, some devices are commonly used, such as water buoys, life jackets, power inflatable lifesaving devices or chemical reaction inflatable lifesaving devices, etc. However, these lifesaving devices have some disadvantages, such as large weight and large volume. , inconvenient to carry, etc., which makes people wearing such devices affect the comfort of swimmers, let alone diving and other underwater operations, and some life-saving systems, simple pressure and three-axis sensors enable the equipment to automatically monitor the drowning state and then Trigger rescue measures, but the trigger mechanism is too complex and often requires a large volume

There are also some life-saving devices that use chemical reaction trigger devices to achieve the purpose of rescue, but the chemical reaction of such products takes a certain amount of time, which affects the timeliness of rescue. Sometimes such products often cause rescue airbag devices due to insufficient response. Can not be fully opened, obviously the current product technology is not mature enough

[0003] The existing patent number is CN107985530A Swimming lifesaving system and its control method. Nitrogen gas is generated through heating and combustion reaction, and the air bag is filled. This method has a slow reaction speed and is not timely enough, and the combustion reaction is often not stable enough, and the amount of nitrogen gas produced is limited, thus Affects airbag inflation

CN111099001A An intelligent anti-drowning wristband. By controlling the rotation of the steering gear, the cam on the rotating shaft pushes the connecting rod to do a translational movement, and the connecting rod pushes the piercing mechanism to do a translational movement to pierce the gas cylinder. Inflating, this method requires a series of mechanical structures to complete, thereby increasing the structural volume of the lifesaving system, and a series of mechanical kinetic energy in the whole process requires a large amount of electric energy to support, which has certain requirements for power supply
