Description
Technical field
The present invention relates to a kind of technical field of intelligence, a kind of air pollution detecting system based on mobile phone terminal.
Background technology
Plentiful along with people's economy, people are more and more higher to the requirement of interior decoration.Owing to finishing material is mostly adopted
With artificial board, filled board, glue, paint, coating, binding agent, granite, marble, ceramic tile and Gypsum Fibrosum etc., these materials are the most how many
Few all contain not four kinds of pollutant such as the formaldehyde of grade, benzene, ammonia, radon, the finishing material of no pollution is non-existent.So-called country
Environment-friendly materials, the most above-mentioned pollutant are within country's allowed band.But decoration marked material is mixed the genuine with the fictitious, all of sale
Business all claims the material of oneself to reach national environmental standard, and consumer is hard to distinguish between the true and false.According to the relevent statistics, newly-decorated house air
Detection qualification rate is the lowest, and this has the reason that finishing material is inferior, also has the reason of unreasonable construction.Maximum being subject to of indoor pollution
Evil person is that those children, anemia of pregnant woman, old man and chronic patient, particularly child are endangered more susceptible to indoor pollution than adult
Evil.On the one hand, because the health of child is grown up, it is higher by 50% than adult that respiratory capacity presses weight ratio.On the other hand, Er Tongyou
The time of more than 80% is to live in indoor, is contaminated injury and is not easy to realize, cannot retrieve when pinpointing the problems.From U.S.
It will be seen that the child of 65% suffers from heavy breathing to some extent in the state expert asthma investigation to causing due to room air pollution
Breathe heavily is from finishing pollution.Harmful substance in Indoor Air after Decoration is mainly: formaldehyde, benzene homologues, ammonia and pm2.5 etc., this
A little materials do the biggest harm to human body.
Air pollution sensor system is for monitoring the concentration of airborne contaminant, the particularly airborne pollution of insalubrity
The concentration of thing.In conjunction with the filtration system being included in air treatment system, air pollution sensor system may be used for monitoring also
Control the concentration being used for receiving the airborne contaminant of the enclosure interior of the scavenging air from air treatment system.Air pollution
Sensing system includes air inlet, gas outlet, sensor unit and air displacement device, and this air displacement device is arranged to build
Vertical from air inlet through the air-flow of sensor unit to gas outlet.This sensor unit is by the interaction with airborne contaminant
And run, such as by using filter to remove airborne contaminant from air-flow or by by the interaction with electromagnetic radiation
Determine that the existence of airborne contaminant in air-flow runs.The sensor unit bag of the air pollution sensor system according to the present invention
Include the filter for removing airborne contaminant from air-flow.As a result, sensor unit generates and has and by filter per unit
The output signal of the amplitude that the amount of airborne contaminant that the time removes is proportional.During operation, the airborne contaminant of increments
It is deposited in sensor unit.Therefore, the amplitude of the output signal measured at certain air pollution level can change over,
Such as because changing filter or filtering feature.The life-span of air pollution sensor system is defined as such time:
The amplitude of the output signal measured under the set condition determined after this time has been changed to exist at the filter of cleaning
In the case of a certain percentage ratio (such as 50%) of initial measurement.
Current research finds to show: if the concentration of PM2.5 is for a long time higher than 10 μ g/m3 in air, mortality risk begins to
Rise.Relation between mortality rate and the air pollution of one middle participant that studies for a long period of time of this Article analysis, finds death
Rate raises relevant with the pollution of PM2.5 and sulfur dioxide.Wherein the harm of PM2.5 can be from toxicological point and ecological angle
Degree considers in terms of toxicological point owing to PM2.5 particle diameter is the least, and have bigger specific surface area respectively, and this is that some are thin
Bacterium virus heavy metal and carcinogen provide good carrier, and PM2.5 is difficult to be stopped by nasal cavity and respiratory tract, is easily brought into
Human body, and be detained in human body, thus the infringement that aggravation is to health.
Carbon monoxide poisoning event happens occasionally, this is because carbon monoxide is combined with hemoglobin in blood and causes group
Knit anoxia.Acute poisoning: headache, dizziness, tinnitus, cardiopalmus, Nausea and vomiting, unable occurs in calomel poisoning person.Moderate intoxication person remove
Outside above-mentioned symptom, also flushed face, lip cherry are red, arteries and veins fast, agitation, instability of gait, confusion, can have stupor.Severe is suffered from
Person remains unconscious, contracted pupil, muscular tension increase, frequently tic, gatism etc..Degree of depth poisoning can be lethal.Chronic Effect:
A certain amount of carbon monoxide of prolonged and repeated suction can cause nerve and cardiovascular damage.
In order to realize the detection to surrounding air, people have invented air ambient detection device, current detection device class
Type is many, but major part formula gas detector all uses gas sensor to detect at present, can only be carried use by tester；When poisonous
Harmful gas could be reported to the police when arriving near person surrounding i.e. detector, it is impossible to realizes providing detection early warning to point out, especially
It is region together, needs to carry out to be carried use by tester when air ambient detection is analyzed, as in blast generation area
Carrying out when detecting in real time of air ambient, current this equipment may not carried blast area by tester and go inspection
Surveying, this detection mode may cause the generation of life dangerous situation.Therefore, develop a kind of new detection device, to adapt to inspection
Survey the needs of environment, have great importance.
