Description

In-car safety alarm

Technical field

Vehicle carried apparatus field is the utility model is related to, especially a kind of in-car safety alarm.

Background technology

With the development of society and the increasingly raising of people's living standard, automobile has become can not in people's daily life The important vehicles lacked, the time that people spend in automobile are more and more.Vehicle air environmental quality turns into people Growing interest hot issue.Vehicle air environment is to maintain close ties with car external environment, the in-vehicle air environment moment Influenceed by car external environment.But generally the pollutant concentration caused by in-vehicle exposure source is significantly larger than outside car, this Mainly due to caused by a large amount of uses of automotive interior material.According to investigations, all different journeys of the ornament materials in automobile at present Degree contains poisonous organic solvent, and these materials constantly discharge pernicious gas to in-car.Contain in some adhesive Substantial amounts of strong carcinogen, such as formaldehyde, benzene,toluene,xylene organic matter, have a strong impact on the health of passenger.Car The interior occupant behavior of itself, also there is very big influence to air quality in vehicle.First, the metabolic activity of human body in itself is Oxygen intake, the process of other secretion is given off carbon dioxide and produced, anoxic in compartment is easy to when long-time travels.No Comfortable in-vehicle air environment not only damages the physical and mental health of passenger, can also influence the state of mind and reaction energy of driver Power.Improve air quality in vehicle, increase ventilation rate, ensure suitable relative humidity and temperature, it is empty that good in-car could be built Compression ring border, comfort level of riding is improved, ensure the health and traffic safety of passenger.

Current most of automobile is fitted with air adjustment air-conditioning system, i.e., using artificial cooling or the method for heating, adjusts Vehicle interior temperature and humidity are saved, so as to which environment inside car is adjusted into proper states, makes occupant all the time in good environment by bus. But the air adjustment air-conditioning system of automobile, the composition to harmful gas in vehicle, content, pollution level and to people can not be realized The Detection ＆ Controling of body Health cost situation.The seriousness of in-vehicle exposure should obtain enough understanding, an external research Test result shows that the driver of more than half suffers from the syndrome of driving triggered by in-vehicle air pollution.Syndrome of driving into One of main inducing for traffic accident, its probability for causing traffic accident to occur are far above fatigue driving and drunk driving.And car If environment pollution goes down for a long time, the respiratory system of major injury people, trigger bronchitis, rhinitis and other disease, or even lead Lung cancer is caused, for vulnerable women and children, influenceing will be bigger.At present, in-vehicle air pollution has been obtained for the world and defended The extensive concern of raw tissue, one of ten big threats of human health have been classified as it.With the fast development of society, vapour is applied to Material on car makes rapid progress with product, but the air quality problems thus triggered are also increasingly severe, poisonous in in-car air Organic matter etc. often there is exceeded phenomenon.Even if single concentration has reached standard, it cannot guarantee that total concentration will not be exceeded.Car Interior air pollution has a strong impact on the health of passenger, and Jian car syndromes are even more the major hidden danger of traffic accident.It is in-car dirty Dye problem has caused the extensive concern of people, and oneself pressure automobile production enterprise of relevant department performs related discharge standard at present Regulation, automobile industry also begin to research and develop new-energy automobile, and automobile power substitutes traditional fuel oil by powered part or all.But People are also far from enough to the attention degree of in-vehicle air pollution.In order to have timely to in-car air condition and variation tendency Solution, ensure that occupant has the environment inside car of a healthiness, ensure the traffic safety of driver, it is necessary to which monitoring in real time is in-car Pernicious gas, accomplish harmful gas concentration transparence, only in this way occupant just can take phase according to in-car air quality The behave answered, early avoid in-vehicle air pollution and pollutant it is exceeded to caused by human body harm.Therefore it is comfortable to ensure In-vehicle air environment, it is very necessary to the real-time dynamic monitoring of in-car air quality and pernicious gas.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of in-car safety alarm, for detecting having for in-car Evil gas content and car body situation, while and alarm in order to being handled rapidly.

Technical scheme is used by the utility model solves its technical problem：Including power supply, human body infrared detector, two Carbonoxide concentration sensor, carbonomonoxide concentration sensor, formaldehyde sensor, car body shock sensor, tilting of car body sensor, Single-chip microcomputer and alarm, the human body infrared detector, gas concentration lwevel sensor, carbonomonoxide concentration sensor, first Aldehyde sensor, car body shock sensor and tilting of car body sensor parallel connect to form detection circuit, the power supply, detection electricity Road, single-chip microcomputer and alarm are sequentially connected in series.

The beneficial effects of the utility model are：Human body infrared detector be used to detecting it is in-car whether someone, as in-car someone When, gas concentration lwevel sensor, carbonomonoxide concentration sensor, formaldehyde sensor, car body shock sensor and tilting of car body Sensor is powered, and detects gas concentration lwevel, carbonomonoxide concentration, concentration of formaldehyde, car body shockproofness and tilting of car body respectively Angle, when gas concentration lwevel, carbonomonoxide concentration or exceeded concentration of formaldehyde, single-chip microcomputer control alarm sends alarm, drives The person of sailing takes measures in time, ventilation of such as driving, opens air purifier；When car body vibration amplitude is excessive or tilting of car body angle When spending big, single-chip microcomputer can also control alarm to send alarm, and after overturn accident occurs in remote location, alarm song can be inhaled Draw neighbouring road Salopian, in order to be rescued in time.
