Waterborne alarm device and application method thereof

Abstract

A waterborne alarm device and an application method thereof are disclosed. The device comprises an infrared sensor located on a shoreside and a grating sensor located in the water. Signal output terminals of the infrared sensor and the grating sensor are connected to a signal input terminal of a microcontroller 1 respectively. A signal output terminal of the microcontroller 1 is connected to a signal input terminal of a voice alarm module and a microcontroller 2 located on a guard room alarm. The signal output terminal of the microcontroller 1 is connected to a microcontroller 3 located on a lifesaving appliance on a water surface. When a person is close to a lakeside, arrives at a dangerous distance and does not fall into the lake, the voice alarm module carries out voice early warning. If a tourist accidentally falls into the water, a shoreside microcontroller 1 simultaneously transmits a signal to the guard room alarm and an intelligent lifesaving appliance in the water; the guard room alarm rings and simultaneously the lifesaving appliance is started so as to realize that the shoreside alarm rings, the lifesaving appliance in the water is started and overboard personnel can be rescued in a gold rescue time period. The device and the method of the invention possess characteristics of convenience, easy realization and high reliability.

Description

technical field [0001] The invention relates to the technical field of lake surface early warning and rescue devices, in particular to a water alarm device and a using method thereof. Background technique [0002] According to the report of the World Health Organization, about 500,000 people die due to drowning in the world every year, and there is no large-scale statistical data in my country at present. According to incomplete statistics, 57,000 people die from drowning in my country every year, and drowning accidents become the number one cause of death in accidents caused by accidental injuries among teenagers. On average, nearly 30,000 children die from drowning every year. It can be seen that drowning death has become one of the main "killers" of human abnormal death. [0003] The main reasons for drowning accidents are as follows: Subjectively speaking, many tourists are unprepared, accidentally fall into the water from rivers, lakes and seaside, and will not adjust...

AI Technical Summary

Problems solved by technology

Unable to call for help in time

Sometimes because of the weak safety awareness of tourists, they only care about having fun and don’t pay attention to their own safety, who will enter the danger, lack of self-protection awareness, and it is easy to cause the consequences of extreme joy and sorrow

Objectively speaking, the safety alarm measures of some artificial lakes in some parks are not in place. Factors such as blind areas and dead angles above and below the water, large water areas, complex water areas, changing hydrology, and reflections on the water surface will cause poor protection and rescue effects and easily cause danger. If the alarm is not timely, the best rescue time will be delayed

Many brave rescuers have not received professional training, and their own swimming and rescue abilities are not strong enough. The drowning person may make violent actions due to panic, which may hurt the rescuer, and may cause more serious consequences of drowning.
