Description
Technical field
The utility model relates to meteorology precipitation fields of measurement, particularly relates to the equipment of simultaneously measuring precipitation intensity and type of precipitation.
Background technology
Quantity of precipitation on the meteorology meaning refers to and drop to the water depth that ground is gathered without evaporation, infiltration or loss.Precipitation intensity refers to the quantity of precipitation in the unit interval, and type of precipitation refers to the weather phenomenon classification of precipitation phenomenon, as: drizzle, rain and snow mixed etc.
Rain gage is the meteorologic instrument of measuring quantity of precipitation and precipitation intensity, and commonly used at present have rain gage bucket, tipping-bucket rain-gauge, a siphon rainfall recorder etc.Rain gage bucket is that rainwater is pooled in container, then by manually being measured; Tipping-bucket rain-gauge is to flow into tipping bucket after rainwater is collected to current-sharing, by the unbalance upset of tipping bucket, measures rainfall; Siphon rainfall recorder is that the liquid level by rainwater rises to promote float and carries out the rainwater metering, and container has been expired rear generation siphon float back to zero again.These several rain gage ubiquity measuring error are large, induction speed slow (a small amount of rainfall is reactionless), can't obtain the shortcoming such as type of precipitation.
Weighing type rain gauge is the rainfall measurement instrument that another kind of precision is higher, its principle is to adopt LOAD CELLS to carry out weighing measurement to the rainwater collected in rain gage bucket, because the sampling resolving accuracy can be very high, so can reach the resolution of very high rainfall or raininess.Yet, due to the factors such as vibration influence of the thermal ataxia that has sensor creep, modulate circuit, outside, when there is no precipitation, its sensor output is not a steady state value, but the false-alarm signal can often occur.What weighing type rain gauge often adopted is the receiving flask of non-hydrocone type, because the precipitation in the siphonage time section can't be responded to, for guaranteeing that receiving flask does not overflow, tends to adopt very large receiving flask volume like this.But the increase of range has also reduced the resolution of sampling, make the ability of the faint precipitation increment of induction reduce.
In aerological sounding and research field, except needs obtain quantity of precipitation information, toward contact, need to provide raindrop size distribution, velocity spectrum, raindrop footpath to compare etc. other parameters more specifically, and these micro-parameters often need to be measured by the optics rain gage.The optics rain gage generally adopts photodiode permutation, line array CCD or area array CCD etc. as sensor, coordinates transmitting illuminant to carry out optical measurement to the raindrop by sample space.The optics rain gage has that reaction velocity is fast, non-cpntact measurement, the advantages such as good environmental adaptability, thus advanced optics rain gage often all possesses the ability that the single precipitation particles of direct measurement obtains raindrop size distribution and type of precipitation at present.Yet because the measurement to rainfall is not direct measurement, but obtain from the signal magnitude of raindrop statistics, so the udometric rainfall measurement precision of optics is not high.
Summary of the invention
The technical matters solved: for the deficiencies in the prior art, the rain gage that the utility model provides optical method to combine with weight method, solving rain gage bucket independent in prior art, tipping-bucket rain-gauge, siphon rainfall recorder etc. exists that measuring error is large, induction speed is slow, can't obtain the shortcoming such as type of precipitation, the defect that false-alarm signal, the large capacity receiving flask of needs, sampling resolution are low etc. often appears in independent weighing type rain gauge, and the independent optics rain gage shortcoming not high to the micro-parameter measuring accuracy.
Technical scheme: for solving the problems of the technologies described above, the utility model by the following technical solutions:
The rain gage that optical method combines with weight method, comprise transmitting illuminant system and receiving optics, between described transmitting illuminant system and receiving optics, forms optical path; The below of described optical path is set to the rainwater-collecting face, and at described rainwater-collecting face, place arranges the rainwater adaptor, and described rainwater adaptor is connected to receiving flask, and described receiving flask is syphon structure; Described receiving flask below arranges LOAD CELLS; Described receiving optics and LOAD CELLS are all in succession to microprocessor.
Further, in the utility model, described receiving optics comprises optical filter and array image sensor, and described optical filter is placed in array image sensor the place ahead, and described array image sensor is CCD linear array or image surface battle array.But the parasitic light of the non-emissive wavelength of described optical filter filtering; Owing to covering or scintillation effect causes the signal intensity of array image sensor, obtain yardstick, speed or other image informations of particle by processing.
Further, in the utility model, described rainwater adaptor is for accepting funnel.
The udometric rainwater measuring method that optical method combines with weight method, the light that described transmitting illuminant system is sent receives by received optical system behind sample space; The parasitic light of the non-emissive wavelength of optical filter filtering in described receiving optics, the array image sensor in described receiving optics is sampled to the precipitation particles in sample space; Described precipitation particles falls into and accepts funnel and enter receiving flask by sample space; Described LOAD CELLS is weighed to receiving flask and collected rainwater weight; Siphon, emptying rainwater, with U trap, occur in described receiving flask when liquid level reaches setting height; Described receiving optics and LOAD CELLS send to microprocessor to be processed, comprehensively export afterwards the measurement signals of synchronization, when described LOAD CELLS detects receiving flask generation siphon, the rainfall signal that described microprocessor records receiving optics is as the offset of gross rainfall.
Beneficial effect: the utility model combines the advantage of optical method and weight method quantity of precipitation and precipitation micro-parameter is measured simultaneously, because rainwater had both passed through sample space, fall into again receiving flask, measured is same object, data result can confirm inspection, the generation of so just having stopped false-alarm mutually; Adopted the measuring principle of two kinds of performance complements simultaneously, the precipitation of same sample space is measured, can bring into play the advantage of two kinds of measuring principles, such measurement result had both obtained accurate quantity of precipitation and had measured, the microcosmic statistical parameter of the precipitation of having got back.Receiving flask can adopt suction bottle, within the time period that siphon occurs, to the measurement of rainfall, can be corrected and make up by the udometric data of optics, so just can reduce the volume of collecting bottle, improves resolution.
