Description
Technical field
The present invention relates to a kind of device of measuring quantity of precipitation, specifically is a kind of device that can measure quantity of precipitation automatically, belongs to the meteorological observation field.
Background technology
Weather conditions can not be ignored the influence of traffic, precipitation, snowfall meeting cause the road surface wet and slippery, cause traffic hazard, particularly heavy showers, strong snowfall weather bring very big influence can for people's trip, even can cause serious consequence, therefore, in time whether mensuration has precipitation and quantity of precipitation data and in time issues early warning information, will well guide the public to arrange plan of travel, avoids unnecessary blocking up and damaging.
At present, the mode of the commonly used measurement quantity of precipitation of meteorological department is to measure with special-purpose quantity of precipitation measuring cup.Specifically be that to adopt diameter be that the Sheng rain mouthpiece of 20cm connects rainwater, contain the rain mouth and make funnelingly, contain rain mouth below udometer is set.Rainwater can directly be poured into and carry out the quantity of precipitation measurement in the quantity of precipitation measuring cup after containing the collection of rain mouth inflow udometer, and according to standard code, the diameter of quantity of precipitation measuring cup is 4cm.If for example snowfall etc. of solid precipitation, directly adopting diameter is that the rain detecting device of 20cm is accepted solid-state water purification, is then the udometer that fills solid precipitation to be brought back indoor, makes it melt the back and measures by the quantity of precipitation measuring cup.Measurement result directly is precipitation (snow) amount of this period, and unit is millimeter.But with artificial metering system, can not in time obtain relevant precipitation and quantity of precipitation data message, in addition, when the rainwater collected or snow-broth are poured into the quantity of precipitation measuring cup and are measured from udometer, have the loss of rainwater or the snow-broth of small part, also can cause the inaccurate of measurement result.
Adopt the mode of automatic observation can reduce delay and the error that manually-operated brings as far as possible, present automatic observation to the precipitation phenomenon, following several method is arranged: one, optical means, utilize particle light-proofness or scattering of light, obtain size and the speed of particle, because diameter and the falling speed of the particle that the different precipitation type is contained are different, and corresponding fixed value is arranged, thereby extrapolate the size of quantity of precipitation; When two, acoustic method, precipitation took place, it is relevant with the raindrop size that raindrop drop on the sound of stainless steel substrates, raindrop are more big, the sound that sends is more big, and 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.But therefore above-mentioned dual mode, can't solve the technical matters of obtaining the real-time aspect graph picture of precipitation material and real-time quantity of precipitation continuously owing to can not in time clear up the precipitation material that has fallen.
Granted publication number is CN101813792B, denomination of invention is the patent of invention of " precipitation automatic observation device ", a kind of precipitation automatic observation device is disclosed, comprise video frequency pick-up head, digital video capture card, microprocessor, air nozzle, transparent slide, described video frequency pick-up head obtains the video image of precipitation material on the transparent slide, its data-interface is connected with microprocessor with the digital video capture card by data line, converts the analog picture signal of its shooting to data image signal and delivers in the microprocessor; Microprocessor is handled, is stored and show described data image signal, make the observation personnel obtain the related data of quantity of precipitation, and the control air nozzle, the precipitation material that in time will drop on the transparent slide is blown away, and therefore can realize putting down in writing continuously other image of precipitation material type.If but this scheme begins precipitation just, might identify less than under the very little situation of quantity of precipitation and can't in time inform observation personnel precipitation, and then remind the wet and slippery its associated antiskid of carrying out in people road surface to prepare, and this scheme is to carry out analyzing and processing and then obtain the related data of quantity of precipitation by the image to the precipitation material, be not the quantity of precipitation that directly measures, the measuring method relative complex.
Summary of the invention
