潜水自救气囊的设计研究

Design and Research of Diving Self-rescue Airbag

为了提高潜水的安全性,潜水自救气囊作为实用型安全装置,通过理论知识对比,发现装置采用GPS模块、压力传感器、单片机等硬件后确实可以提高装置的安全性能。其使用方法是,当潜水人员在水下发生危险时,通过按下触动开关来接通装置内部电路,电流通过电爆管发生爆炸引燃火药粉,引发气体反应剂发生反应,产生的大量气体使伸缩气囊急速膨胀,在极短时间内形成一个浮力球,产生巨大浮力,拖动潜水人员浮出水面,实现自救。装置优点就是可以实现快速自救和GPS定点救援,这也是装置最终需实现的两项功能。

In order to improve the safety of diving,diving self-help airbag as a practical safety device,through the comparison of theoretical knowledge,it can be found that the device using GPS module,pressure sensor,SCM and other hardware can indeed improve the safety performance of the device.Its usage is,when divers danger underwater,by pressing the touch switch to switch the internal circuit,current through electric detonator explosion fire ignition powder,cause gas reactant,the large amount of gas is used to make telescopic airbags rapidly expand,in a very short time to form a buoyancy ball,a huge buoyancy,drag the divers surfaced,healing itself.The advantage of the device is that it can achieve rapid self-rescue and GPS fixed-point rescue,and it is also the final need to realize the two functions of the device.
