Description
Technical field
The present invention relates to a kind of Detection of Air Quality for the vehicles, warning device and method, relate in particular to for the Detection of Air Quality in aircraft cabin, warning device and method.
Background technology
Along with the raising day by day of living standard, aircraft becomes the first-selection of people's trip gradually.Aircraft cabin is as a confined space, its for passenger takes during flight is provided, the place of rest, amusement, therefore the comfort level in cabin has directly affected the comfort level of passenger's airplane.And an important indicator of cabin comfort is exactly air quality, because aircraft cabin is all airtight conventionally, and sometimes passenger will stay even ten several hours upper a few hours in cabin.Large aircraft now generally all has the air-conditioning system of self, and the air regulating mainly comes from engine bleed and part cabin and recycles air.The external environment condition of aircraft on the ground and in flight course is all comparatively severe sometimes, for example, summer, airport is very hot, especially before not yet taking off, a lot of aircrafts cannot be opened air-conditioning completely because of dynamical problem, and sometimes because of delayed problem, passenger often will wait for a long time under this environment.In addition, aircraft is ultraviolet in the time of terrestrial space during flying is also very strong conventionally.And current large aircraft more and more adopts compound substance manufacture, these compound substances be heated or ultraviolet impact under all likely in cabin, discharge VOC, namely volatile organic compounds.Meanwhile, due to the use of engine bleed, also may in cabin, introduce some carbon monoxide and carbon dioxide.The content of carbon dioxide too much can cause Lactoferrin to reduce in conjunction with oxygen ability, is first that brain lacks oxygen and feels dizzy, and numb limb is unable besides, finally shock.As supplemental oxygen will be because of shock brain death, heart failure not in time.CO is the molecular formula of carbon monoxide, under usual condition, CO is colourless, odorless, tasteless, poisonous gas, the poisoning reason of CO be because CO enter after human body can and blood in haemoglobin combination, and then squeeze the combination of haemoglobin and oxygen, thereby occur anoxic and cause poisoning.Gently can there is headache, dizziness, insomnia, blurred vision, tinnitus, feel sick, vomiting, malaise, tachycardia, of short duration faintness, also can cause lip, nail, the mucocutaneous cherry-red that occurs, hidrosis, blood pressure first raises and reduces afterwards, heart rate accelerates, arrhythmia cordis, agitation, momentary sensation and moved apart (still have thinking, but can not take action).Symptom continues to increase the weight of, and can occur drowsiness, stupor, when serious, can enter rapidly comatose state, and initial stage four limbs flesh tension force increases, or has paroxysmal tonic spasm; Late period, flesh tension force significantly reduced, patient's pale complexion or livid purple, and blood pressure drops, mydriasis, finally because respiratory paralysis is dead, also has serious complication and sequelae through rescuing survivor.The World Health Organization (WHO) is the general name of fusing point boiling point volatile organic compounds between 50-260 DEG C lower than room temperature to the definition of TOVC.Generally comprise the materials such as formaldehyde, ammonia, ethylene glycol, ester class.In the time that VOC reaches finite concentration, can cause headache, feel sick, vomiting, the symptom such as weak, when serious, even cause tics, stupor, injure liver, kidney, brain and nervous system, cause the serious consequences such as failure of memory.Mainly come from the air-conditioning system that recycles air in engine bleed and part cabin and break down and cannot be detected in time and alarm if used, so above-mentioned harmful gas will cause deleterious effect to passenger's comfort level, or even injury passenger's health.Other the vehicles, such as automobile, submarine or rolling stock etc. are also faced with same problem.
Summary of the invention
The present invention is intended to overcome above-mentioned defect, a kind of Detection of Air Quality for the vehicles and warning device are provided, concrete, comprise airborne power supply, gas sensor, microprocessor, buzzer siren and communication module, wherein airborne power supply, for gas sensor, microprocessor, buzzer siren and communication module provide electric energy, characterized by further comprising liquid crystal indicator.
Preferably, the form that gas sensor is preferably popped one's head in.
Preferably, sonde-type gas sensor comprises head and installation portion, is provided with bed filtration structure at the front end of head
Preferably, filtration comprises metal net layer, middle spongy layer and plastic eyelet layer from outside to inside successively, and metal net layer, middle spongy layer and plastic eyelet layer adopt together with resin tight bond.
Preferably, after filtration, be provided with horn-like air intake opening, this horn-like air intake opening endpiece is connected with airflow line, and the space between the head of hollow shape and tubaeform air intake opening and gas channel can filling sponge or foam.
The invention still further relates to a kind of method of carrying out gas detection and warning for the Detection of Air Quality in aircraft cabin and warning device of the present invention of utilizing, it is characterized in that comprising the steps: gas sensor Real-time Collection and detect the gas componant in cabin space, recording the content of carbon dioxide, carbon monoxide; Gas sensor imports the data that collect into microprocessor, and when gas exceedes after predetermined threshold value, in system, buzzer siren is reported to the police, and which kind of gas is exceeded standard and shown by display screen; After reaching specified conditions, signal is reached communication module by microprocessor, sends information to crew or ground control tower by communication module, allows related personnel initiatively take certain measure; After recovering normally, sound all clear.
Preferably, described threshold value can be for example that the concentration that gas concentration lwevel reaches 2000ppm or carbon monoxide reaches 1000ppm.
Utilize gas-detecting device of the present invention and method can effectively detect vehicle occupant and take the air quality in space, increase the comfort level that passenger takes, reduce the risk that vehicles confined space damages passenger's health.
