Description
Technical field
The present invention relates to lifesaving appliance technical field, specifically a kind of Intelligent lifesaving circle based on speech recognition.
Background technique
Every year about the news to drown, can translate on the report in area throughout the country.The especially raising of temperature,
Swimming peak period is also arrived therewith, and high-incidence trend is presented in drowned accident.According to incompletely statistics, China is death due to drowned every year
About 57000 people of number, drowning is also the number one killer of the lethal accident of teenager's unexpected injury.The reason of accident occurs has very much,
Sometimes because person in distress raises a cry, emergency but no one hear or hear cry but dare not implement to succour easily, sometimes because of water
Conditional complexity cannot sue and labour easily.If improper measures that rescuer took sue and labour, are easy to cause because being short of physical strength
The serious consequence that more people drown.
Lifebuoy is a main species in the most common water survival gear and lifesaving appliance, current many lifesaving
Work is completed using lifebuoy.Lifebuoy is usually by cork, foamed plastics or the lesser lightweight material of other specific gravity
It is made, canvas, plastics etc. are wrapped in outside.When person in distress is overboard, rescuer can easily jettisoning lifebuoy to person in distress, from
And realize rescue purpose.The lifebuoy rescued about the shout using person in distress is based on such as patent No. CN105083499A
The automatic positioning lifebuoy of sound control technique, when person in distress occur dangerous situation by shout to cry for help when, lifebuoy starting simultaneously it is automatic
Reach person in distress at one's side；But the speech range very little that this method can recognize, and positioning accuracy is poor, cannot accurately determine chance
The specific location of dangerous person, swim ring cannot be made to reach person in distress causes rescue to fail at one's side.
