Description

Anti-drowning automatic rescue system and anti-drowning automatic rescue method

Technical Field

The invention relates to the technical field of rescue systems, in particular to an anti-drowning automatic rescue system and an anti-drowning automatic rescue method.

Background

In seconds after a human body is drowned, the human body instinctively holds the breath, causes diving reflex (apnea, bradycardia and severe contraction of peripheral blood vessels), and ensures blood supply of the heart and the brain. Subsequently, hypercapnia and hypoxemia occur, stimulate the respiratory center, enter a non-spontaneous inspiration period, and as inspiratory water enters the respiratory tract and alveoli, the airway is filled to cause severe hypoxia, hypercapnia and metabolic acidosis, and drowning leads to death or brain damage in less than 2 minutes. Therefore, after drowning, the drowning person takes aid measures quickly to get away from the drowning state, which is an important means for ensuring life and body health. 8 thousands of children die of injury every year in China. Drowning is the leading cause of death from injury to children. Children (including most adults) are in a panic state after falling into water accidentally, self-help is difficult to implement, and external help is also difficult to match, so tragedy happens. Sudden twitches, or knocks, while swimming can also make self-aid and external aid difficult to administer. Therefore, there is a need for a device that can automatically determine the status of a diver and reasonably take automatic rescue measures to reduce the occurrence of such drowning events.

There is a manual inflatable life jacket on the market, when a user is in a drowned state, the rope is manually pulled, and the life jacket is inflated to realize rescue.

The above-mentioned manual inflatable life jacket has the disadvantages.

First, if the drowning person accidentally falls into water or twitches, the drowning person will be in a hurry state, and it may be difficult to complete the operation of pulling the rope to inflate the umbrella.

Secondly, if the diver does not wear the diving device to dive, under the condition of long-term oxygen deficiency or water choking, the diver is confused or even disordered, and the action of pulling the rope to inflate can not be completed.

And thirdly, if the swimmer is unconscious when being bumped on the head, the action of inflating the pull rope cannot be finished at all.

And fourthly, a distress signal can not be sent out, and a drowning person can not be helped in time to discharge and suck, so that the body is damaged.

step S6: detecting a warning release signal once per second;

step S7: judging whether the warning releasing signal is generated or not, returning To the step S2 when the warning releasing signal is released, judging whether the initial time value To is greater than 5 or not when the warning releasing signal is not released, and starting the self-rescue state when the initial time value To is greater than 5; when the initial value To is less than 5 and the initial value To = To +1, go back To step S6 again;

step S8: starting the self-rescue state and then entering the ending state.

The invention is further illustrated by the following examples:

control mainboard 2 uses the signal of soaking of sensor 1 that soaks as the drive variable, through the mode setting of difference, whether automated inspection user is in drowned state, specifically as follows:

firstly, an onshore mode: in this mode, the control board 2 considers that the flooding sensor 1 should not send any flooding signal. Therefore, once a user falls into water, the immersion sensor 1 sends a signal, and the control mainboard 2 judges that the user is in a drowned state and triggers a self-rescue standby state.

Secondly, swimming and diving modes: in this mode, the control board 2 considers that the flooding sensor 1 sends a discontinuous signal. Therefore, when the user swims normally, the immersion sensor 1 will send out discontinuous signals because of being in the alternate state of immersion and non-immersion, and the control main board 2 keeps the safe standby state; in case sensor 1 soaks in succession, the length of time of signals surpasss the safe value that the system set up, and control mainboard 2 judges that the user is drowned state, triggers the state of awaiting the opportune moment of saving oneself.

Thirdly, the control main board 2 triggers a self-rescue standby state and can send out a prompt tone for 5 seconds, if the drowning state is judged by mistake, a user needs to manually input an operation instruction on the control panel 3 to enable the control main board 2 to release the self-rescue standby state and recover the safe standby state; if the state of saving oneself and awaiting orders after 5 seconds is not relieved by manual, then control mainboard 2 gets into the state of saving oneself immediately, and SOS device 4 sends the chimes of doom, triggers the pilot lamp and sends SOS signal respectively. The communication module 403 in the distress device 4 sends distress information and position information, the signal transmitting and receiving base station forwards the distress information and the position information to a specified mobile phone, the mobile phone reads the distress information and the position information, and a touch screen of the mobile phone displays that a guardian knows the occurrence of a drowning condition and determines the position of the drowning person. For example, the touch screen of the mobile phone displays SOS characters, or the speaker of the mobile phone broadcasts help-seeking sound.

The present invention is not limited to the above-described preferred embodiments, but rather, any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
