Description

A kind of for the online monitoring device of automobile inner air quality monitoring
Technical field
The present invention relates to a kind of monitoring device, especially a kind of for the online monitoring device of automobile inner air quality monitoring.
Background technology
Along with growth in the living standard, people more and more pay close attention to the quality of life of self.But along with the continuous intensification of house fitting-up, the widespread use of various building materialss, under high temperature was exposed to the sun, the pollutants such as the formaldehyde in car, benzene can be multiplied, and the environmental health problem more and more receives publicity and is troubling.Various related disorders is noted all kinds of physics and existence chemical factor in indoor environment more such as the appearance of the stimulation of eyes, respiratory tract and skin, dizzy, decrease of memory uncomfortable in chest, headache and other inadaptable senses makes people.
The level of indoor some pollutant is far longer than outdoor, the volatile organic compounds (VOC) in FASHIONHOME particularly, such as the concentration of aromatic hydrocarbon (benzene,toluene,xylene etc.), ketone and aldehydes, ammonia and amine, halogenated hydrocarbons, sulfo-hydro carbons, unsaturated hydro carbons etc. is quite high, be enough to human health is consisted of harm.
Summary of the invention
The object of the invention is to the pollution for air in car, proposed to be used for the interior online monitoring device of air quality monitoring of automobile.This monitoring device can detect in real time and show current environment air quality, temperature and humidity, can send sound and light alarm during the TVOC content overproof in air being detected.
Technical scheme of the present invention is: a kind of for the online monitoring device of automobile inner air quality monitoring, this monitoring device comprises: air mass sensor, temperature sensor, humidity sensor, single-chip microcomputer, LCD display, key circuit, sound light alarming circuit, booster circuit, clock circuit, serial communication circuit, charging circuit, battery; Temperature sensor and humidity sensor are connected respectively to many input AD end of convert of single-chip microcomputer, and the air mass sensor output terminal is connected to the I of single-chip microcomputer 2The C input end; The charging circuit output terminal is connected to the lithium battery input end.The output terminal of lithium battery is connected to the booster circuit input end, and sound light alarming circuit, LCD display, key circuit are connected respectively to the Single-chip Controlling unit; Air mass sensor adopts the sensor assembly of automatic calibration.LCD display adopts LCD display backlight.Booster circuit adopts DC/DC voltage stabilizing chip.Serial communication circuit adopts USB to turn serial port chip.
