Automobile children anoxia protection device started via in-vehicle audio frequency

Abstract

The invention relates to the field of automobile manufacturing and in particular relates to an automobile children anoxia protection device started via an in-vehicle audio frequency. The automobile children anoxia protection device comprises a control system, an in-vehicle oxygen monitoring system, a critical oxygen content alarming system and an emergency managing system, wherein when parking time exceeds 30 minutes, automobile windows and doors are closed and the in-vehicle audio frequency control device is stimulated by over 60 db high frequency sound in the automobile, the children anoxia protection device is started; after the control system receives oxygen content data monitored by the in-vehicle oxygen monitoring system in real time, a comparison is made between the oxygen content data and the set critical oxygen content; and when in-vehicle oxygen content reaches to or is lower than the critical oxygen content, the critical oxygen content alarming system is started and the emergency managing system is started at the same time, so life safety of children locked in the vehicle can be effectively protected.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a child hypoxia protection device for passenger cars activated by in-car audio. Background technique [0002] The air that people inhale, calculated by volume, contains 20.93% oxygen and 0.03% carbon dioxide; in the exhaled gas, carbon dioxide drops to about 3.5%, and oxygen drops to about 17%. According to statistics, adults inhale about 6.5L of air per minute in a resting state, so they need to inhale nearly 10,000 liters of air every day. The normal oxygen content in the air is 21%. When the oxygen content is lacking, it will cause asphyxiation. When the oxygen content is 12% to 15%, people will have shortness of breath, headache, dizziness, fatigue and weakness, and slow movements; Paralysis; when the oxygen content is 6%-8%, people will faint and lose consciousness; when the oxygen content is lower than 6%, people will die within 6-8 minutes; when the oxygen content...
