Description
Technical field
The utility model relates to automation fields, more particularly to a kind of hail simulator.
Background technique
Precipitation class weather phenomenon measuring instrument basic functional principle is that transmitting terminal generates a branch of collimated light beam, and receiving end is with saturating
The optical signal received is converted to electric signal by mirror and photodiode, and collimated light beam coverage area is detection precipitation particles
Air sample sample space.Measuring principle are as follows: the light signal strength received will be caused when precipitation particles pass through sample space
Weaken, particle diameter is related to the amplitude of attenuated optical signal, and particle rapidity is related to the attenuated optical signal duration.Precipitation class day
Gas phenomenon measuring instrument by attenuated optical signal amplitude and duration by specific Processing Algorithm calculate precipitation particles speed and
Partial size judges precipitation particles type after filtering out the interference signal formed by the non-precipitation particles such as floating dust, leaf, feather, realizes drop
The automatic identification of water class weather phenomenon.
And for the test device of precipitation class weather phenomenon measuring instrument, relevant apparatus in the prior art is fewer, most often
It is to paste simulation patch on the transparent former disk of a controllable rotating speed, for emulating the interception of precipitation particles；By institute
It states transparent former disk and is placed in the scopic test zone of laser precipitation phenomenon and rotate, so that the simulation patch reaches certain line
Thus speed plays the effect of simulated precipitation particle.But the device has the following deficiencies:
(1) in analog hail weather phenomenon, nature hailing particle is 3D three-dimensional shape, and above-mentioned simulation patch is
2D flat shape, it is larger with virtual condition difference.In view of spherical hail surface optical reflectivity is higher and optical signal scattering is strong
Degree is also more strong, and when same diameter, the two is different to the attenuation degree of collimated light beam light intensity signal.According to above-mentioned precipitation class day
Gas phenomenon measuring instrument basic functional principle, this phenomenon will increase hail particle diameter and data noise.
(2) transparent disc itself will increase the light refractive index of air sample and reduce optical transmittance, consider optics folding
Phenomenon is penetrated, transmitting terminal collimated light beam will occur slight overall offset and signal strength across transmission direction after transparent disc and subtract
It is weak, it is unfavorable for accurately measuring hail partial size.
(3) country has been formed precipitation class weather phenomenon measuring instrument transmitting terminal collimated light beam coverage area and typically about grows
200mm, wide 30mm, high 1.0mm.Simulation patch on transparent original disk must be rotated in Devices to test sample region, and to keep high speed
The diameter of stability when rotation, transparent disc cannot be too big.When analog hail falls, transparent disc linear velocity is higher, will
The patch high frequency time that will cause analog hail in the short time passes through sample region.Under natural conditions, hail particle is more sparse, usually
There will not be a large amount of hail particles to pass through narrow plane in a short time, the patch high frequency time of analog hail is worn in above-mentioned Patent equipment
More precipitation class weather phenomenon measuring instrument sample region may cause observed result exception.
(4) under natural conditions, the position for passing through precipitation class weather phenomenon measuring instrument sample region when hail particle falls has
Randomness.After being installed on the detection device of precipitation class weather phenomenon measuring instrument in the prior art, the patch of analog hail
Sample region can only be passed through from fixed position with fixed-direction, the motion process difference to fall at random with hail particle is larger, detection
As a result representativeness is not comprehensive enough.
