Description
Technical field
The present invention relates to a kind of on-line monitoring systems of pollen in the monitoring technology of pollen in air more particularly to air.
Background technology
Pollen contamination is an importance of atmosphere pollution.Pollen contamination can cause pollen hypersensitivity to react, it is one
Most common and most important one kind in allergic reaction is cut, seasonal allergic rhinitis, asthma and dermatitis etc. can be induced.Pollen mistake
The severity of symptom of quick patient has correlation with pollen classification, concentration.Therefore, carry out the research work of pollen contamination, point
Type, concentration, seasonal variations and the spatial distribution for analysing pollen in air have clinical diagnosis and treatment allergic reaction disease important
Meaning.It carries out pollen monitoring and pollen is provided and is reported to the public that understanding of the public to allergic reaction disease can be deepened, remind
Patient takes preventive measures.
Morphology discrimination method is taken in the discriminating of pollen type mostly at present.Offline mode is generally used to acquire pollen, system
Standby pollen samples are for microscopic analysis.By differentiating that the morphological feature of pollen determines its classification, category grouping sheet can be generally identified
Position, can only identify kind under rare cases.The concentration investigation method of pollen mainly has natural sedimentation and air containment sampling method.
Natural sedimentation is on the weight glass slide that binder is kept flat to being coated with from descending slowly and lightly in air of pollen itself, and what is measured is single
The pollen concentration of plane product.Air containment sampling method is to acquire pollen samples using modes such as compression, pumping, shock or filterings,
What is obtained is the pollen type and concentration of unit interval unit volume.Pollen is always dense in the air that two kinds of different sampling methods count
There are significant differences between degree and each kind pollen Particle density.Usually, air containment sampling method acquisition pollen Particle density is much larger than
Sedimentation.The sampling of sedimentation pollen is affected by meteorologic factor.Usual air containment sampling method can more accurately reflect air
The type and concentration of middle impact pressure casting, and pollen concentration general in the world is the pollen amount of unit interval unit volume, because
This is conducive to be compared with international similar monitoring using air containment sampling method.

Sampler etc..Rotorod samplers are to stick stick machinery rotating acquisition pollen samples using transparent organic glass, by glass bar
Direct staining is placed on microscopically observation.Hirst samplers are drawn air into from crack, are arranged in the windward side in crack
One glass slide, and with certain speed mobile collection pollen samples.Burkard samplers are to fix 2 at isometric shaft both ends
A sampling base item makes sampling base relative atmospheric move with constant rotary speed, utilizes the principle of solid inertial impaction, sampling
Pollen in air is sticked to its acquisition surface pollen by base windward side.Pollen samples after the acquisition of these methods can be placed in micro-
Observation detection is carried out under mirror, is a kind of off-line monitoring mode.Since microscope detection needs to expend a large amount of manpowers and time, at present
Some external areas have begun to use the discriminating and counting that image capturing system carries out pollen.The pollen samples good by sample preparation is acquired
It is placed under microscope, differentiates allergic disease using image capture system acquisition pollen image and using image analysis software, carry out
Statistic of classification.This method can improve the efficiency of pollen discriminating, but still be a kind of off-line method.
In conclusion existing pollen monitoring analysis system be there are problems that, if sampling analysis system is in sampling, system
Sample process may cause sample loss；Waste of manpower and time, efficiency are low；It cannot achieve online acquisition and in real time analysis pollen sample
Product cannot reflect pollen concentration distribution characteristics etc. in air in real time.
