Background technology
The precipitation weather phenomenon that defines in meteorological field comprises rain, shower, drizzle, snow, snow shower, rain and snow mixed, battle array property rain and snow mixed, graupel, granular snow, ice pellets, hail.To the robotization identification of precipitation phenomenon, following several method is arranged at present:
One, optical means----particle light-proofness:
Principle: a lasing fluorescence source (laser diode) produces a branch of parallel beam, and imaging diode is at the energy of receiver lens one side measuring light and be converted to electric signal.Pass through infrared beam when a precipitation particles whereabouts, received signal weakens.Condensation of moisture body particle size determines that by the degree of brightness deepening the concrement decline rate was determined by the signal weakening duration.
The diameter and the falling speed of the contained particle of different precipitation type are different, and corresponding fixed value is all arranged, and type of precipitation just adds up definite by diameter and falling speed to all particles.Representative products: the German OTT Parsivel of company laser precipitation particles spectrometer; Ties company laser rain gage.
Two, optical means scattering:
Principle: during raindrop process Ray Of Light, because the diffraction effect of raindrop causes the flicker of light, carry out analysis of spectrum after passage of scintillation light is received, its analysis of spectrum result is relevant with the size and the speed of raindrop.Representative products: Vaisala FD12P; The OWI-430 of OSI company; PWS100.
Three, acoustic method---acoustic sensor:
When precipitation took place, raindrop dropped on that the sound of stainless steel substrates is relevant with the raindrop size, and raindrop are big more, and the sound that sends is big more.Acoustic sensor is determined the raindrop size according to this feature, and determines precipitation intensity and precipitation total amount according to the raindrop number on the unit interval disk.In addition, acoustic sensor also drops on distinct sound on the stainless steel sensor according to hail, determines hail.Representative products: the current weather phenomenon sensor of Vaisala PWD12/PWD22.
Above product all has the high and inaccurate defective of indirect detection of acquisition expenses.
