Description
Technical field
The present invention relates to the monitoring technology of pollen in air, particularly relate to the on-line monitoring system of pollen in a kind of air.
Background technology
Pollen contamination is an importance of atmospheric pollution.Pollen contamination can cause pollen hypersensitivity to react, and it is the most common and most important one in all allergic reactions, can bring out seasonal allergic rhinitis, asthma and dermatitis etc.Severity of symptom and pollen classification, the concentration of pollen allergic patients have correlativity.Therefore, carry out the research work of pollen contamination, in analyse atmos, the kind of pollen, concentration, seasonal variations and space distribution, significant for clinical diagnosis and treatment allergic reaction disease.Carry out pollen monitoring and provide pollen report can deepen the understanding of the public to allergic reaction disease to the public, reminding patient to take preventive measures.
Morphology discrimination method is taked in the discriminating of current pollen kind mostly.General use offline mode gathers pollen, prepares pollen samples for microscopic analysis.By differentiating that the morphological feature of pollen determines its classification, generally can identify genus taxonomical unit, only can identify kind under rare cases.The concentration investigation method of pollen mainly contains natural sedimentation and air containment sampling method.Natural sedimentation descends slowly and lightly from air to scribbling on microslide that binder keeps flat by the weight of pollen itself, and what record is the pollen concentration of unit area.Air containment sampling method adopts to compress, bleed, to clash into or the mode such as filtration gathers pollen samples, and what obtain is pollen kind and the concentration of unit interval unit volume.Significant difference is there is between pollen total concentration and each kind pollen Particle density in the air of two kinds of different sampling method countings.Usually, air containment sampling method gathers pollen Particle density much larger than sedimentation.The sampling of sedimentation pollen is larger by meteorological factor influence.Usual air containment sampling method can reflect kind and the concentration of impact pressure casting in air more truly, and pollen concentration general is in the world the pollen amount of unit interval unit volume, air containment sampling method is therefore adopted to be conducive to comparing with international similar monitoring.
Apply more air containment sampling thief in the world and mainly contain Rotorod sampling thief, Hirst sampling thief, Burkard sampling thief etc.Rotorod sampling thief uses transparent organic glass to stick excellent mechanical rotating acquisition pollen samples, and glass bar direct staining is placed on basis of microscopic observation.Hirst sampling thief is by air intake from crack, arranges a microslide in the windward side in crack, and with certain speed mobile collection pollen samples.Burkard sampling thief fixes 2 sampling base bars at isometric rotating shaft two ends, with constant rotational speed, sampling base bar relative atmospheric moved, utilize the principle of solid inertial impaction, and the pollen in air is bonded at its acquisition surface pollen by sampling base bar windward side.Pollen samples after these method collections carries out observation and detects under can being placed in microscope, be a kind of off-line monitoring mode.Because microscopic examination needs at substantial manpower and time, more external areas have brought into use image capturing system to carry out discriminating and the counting of pollen at present.Under pollen samples good for collection sample preparation is placed in microscope, uses image capture system acquisition pollen image also to utilize image analysis software to differentiate allergic disease, carry out statistic of classification.This method can improve the efficiency that pollen is differentiated, but still is a kind of off-line method.
In sum, existing pollen monitoring analysis system also exists some problems, as sampling analysis system may cause sample loss at sampling, sample making course; Waste of manpower and time, efficiency is low; Online acquisition and real-time analysis pollen samples cannot be realized, pollen concentration distribution characteristics etc. in air can not be reflected in real time.
