Description
Technical field
The utility model relates to atmospheric environment detection technique field, relates in particular to a kind of mobile vehicle-mounted detection system that detects Atmospheric Particulate Matter thing PM2.5 concentration.
Background technology
Research is suitable for PM2.5 environmental monitor and the cloud computing technology of vehicle-mounted mobile, coordinate existing PM2.5 monitoring station, city, in time, accurately also reflect all sidedly air quality and trend, for environmental protection, pollution source monitoring, urban planning etc. provide the foundation of science, in conjunction with elements such as industrial layout, urban transportation, populations, carry out system research, close supervision urban air quality also plays positive technical support effect.
Be suspended in airborne liquid state and solid granulates shape material is referred to as Atmospheric particulates. Various particles are dispersed in air and have formed a metastable suspension system, conventionally according to particle diameter, Atmospheric particulates are divided into: overall suspended pellet TSP, corase particles PM10 and fine particle PM2.5. Particle size is the key factor that affects Atmospheric particulates harmfulness, and fine particle PM2.5 diameter is equivalent to human hair's 1/10th, and particle aerodynamic size size determines that it enters respiratory tract and the delay in respiratory tract. Fine particle PM2.5 can directly enter bronchus after being inhaled into human body, disturbs lung normally to work, and causes the multiclass disease that comprises the aspect such as asthma, bronchitis. The scattering theory of Mie is pointed out: when the molecule including fine particle is subject to light irradiation, if the order of magnitude at optical wavelength place and particle diameter are suitable, luminous energy is mainly decayed with the form of light scattering. Mie scattering possesses following three large optical signatures: 1) scattered light intensity distributes and changes along with the variation of angle. When lambda1-wavelength is during much smaller than particle diameter, scattered light light distribution complexity. 2) increase with particle diameter, forward scattering number of photons increases relatively, and rear orientation light subnumber reduces relatively. 3) when particle diameter is during much larger than diffuse lightwave, the diffraction of light mainly occurs, now wavelength and particle diameter are very little on the impact of scattered light. Based on the thinking of Mie scattering, fine particle is subject to can send scattered light signal after illumination, and the scattered light receiving and particle concentration present a kind of linear relationship, can calculate atmosphere particle concentration by this principle. At present 350 meters of urban areas have particulate pollutant to exist below substantially, especially big city pollution level is serious in China city, because industrial information degree is still in reduced levels, Urban Public constantly promotes for the pollution attention rate of PM2.5, the monitoring of urban area PM2.5 is seemed and become more and more important.
The PM2.5 environmental monitor of existing employing light scattering method is manufactured according to particulate Mie scattering theory. Its operation principle is by beam detection Atmospheric particulates size, when Atmospheric particulates order of size is equal to or greater than light wavelength, just can produce optical energy attenuation, its form of expression is mainly scattering of light, and such monitor mainly comprises the parts such as light source, lens, reflective mirror, photodetector, signal amplifier and signal of telecommunication analysis circuit. In the time that Atmospheric particulates are subject to light to irradiate concurrent third contact of a total solar or lunar eclipse line scattering phenomenon, photodetector utilizes the mode of reflective mirror condenser lens, transform to complete photosignal by catching scattered light, after subsequently the photosignal obtaining being processed in real time by preposition amplification and noise filtering etc., in signal of telecommunication analysis circuit, carry out the calculating of pulse generation amount. Because pulse is directly proportional to Atmospheric particulates relative concentration, system often receives pulsatile once signal and just represents that detector receives a scattered light. By the atmosphere data that many groups are collected after measuring under identical atmospheric environment, utilize Technology of Data Fitting to calculate and obtain the Atmospheric particulates data that PM2.5 environmental monitor is measured. At present China PM2.5 environmental monitor manufacturing enterprise mostly adopts optical means design and manufactures PM2.5 detector, in design by utilizing ray dynamic heat systems technology to detect error to reduce. In use adopt lithium battery to power to detection system, due to objective factors such as lithium battery own vol is large, cost, weight, chargings, existing PM2.5 environmental detector is also not suitable for vehicle-mounted mobile use. Investigate discovery by domestic market: existing environmental monitoring background data base still, mainly based on traditional relational system, is difficult to adapt to the demand of growing mass data storage, large-scale data analysis and application.
