Description
Technical field
The present invention relates to the detection technique of snow depth, a kind of High Precision Automatic infrared snow feelings detection device.
Background technology
Accumulated snow, as one important freshwater resources highstrung to climate change fact, is Southwestern China and the Northwest
The main Source Of Supply of river flow, snowmelt runoff plays particularly important in the rational allocation and utilization of this area's water resource
Role.Therefore, strengthen, in this area about the research of snowmelt runoff monitoring method, improving water resources management and damage forecasting water
Flat, the strategic protection for China's water security and energy security has very important realistic meaning.At present, both at home and abroad about
The detection method of snow depth can be divided into two classes: a class is the direct method of measurement, relies primarily on weatherman by carrying out with snow stake
Artificial multimetering snow depth, northern China weather station mainly adopts in this way, and its advantage is that data are reliable, but shortcoming is
Cost of labor is high, labor intensity is big, and cannot carry out the most real-time Aulomatizeted Detect in same place.Another kind of is to use to surpass
Sound wave, laser and video image technology realize the Aulomatizeted Detect to snow depth, and ultrasonic Method for Measuring relies primarily on ultrasound wave
Generator sends pulse or the continuous signal of certain frequency, according to the snow face reflected signal collected by receptor, tries to achieve accumulated snow
The degree of depth；Laser optical method is similar with the principle of ultrasonic Method for Measuring, and the signal simply sent is frequency the most higher laser arteries and veins
Punching or continuous signal；The scale with a scale that video image measurement method mainly utilizes photographing unit shooting to be upright in accumulated snow is real
The measurement of existing snow depth.Ultrasound wave and laser optical method are affected by environment very big, and general measure is apart from comparatively short, and in pole
End low temperature environment is very easy to break down, although video image measurement method can reflect on-the-spot accumulated snow to a certain extent
Depth profile, but owing to it cannot reflect the snow deposit inside generating and vanishing process when melting, therefore also cannot be to snowmelt runoff
Change carry out Accurate Prediction and forecast.Based on this, it is necessary to invent a kind of brand-new snow depth detection device, existing to solve
The problems referred to above with the presence of the detection method of snow depth.
Summary of the invention
The detection method cost of labor that the present invention is to solve existing snow depth is high, labor intensity big, cannot be same
Place carry out the most real-time Aulomatizeted Detect, affected by environment big, cannot reflect that the snow deposit inside when melting is raw and disappeared
The problem of journey, it is provided that a kind of High Precision Automatic infrared snow feelings detection device.
The present invention adopts the following technical scheme that realization:
A kind of High Precision Automatic infrared snow feelings detection device, including tri-prismoid, supporting steel pipe, three rectangle uncovered box bodys, three
Individual rectangle PCB, three infrared emission receive pipe array, three rectangle poly (methyl methacrylate) plates；Wherein, the lower end of tri-prismoid
Face offers central pit hole；The upper end of supporting steel pipe is plugged in central pit hole；The outer cassette bottom of three rectangle uncovered box bodys is respectively
It is fixed on three sides of tri-prismoid；The back side of three rectangle PCB is individually fixed in three rectangle uncovered box bodys
Interior cassette bottom；Three infrared emission receive pipe array and are individually fixed in the front of three rectangle PCB, and three infrared emission
The signal transmission ends receiving pipe array is connected with the signal transmission ends of three rectangle PCB respectively；Each infrared emission connects
Closed tube array all includes that several infrared emission receive pipe, and each infrared emission receives the pipe axis direction etc. along tri-prismoid
Away from arrangement；Three rectangle poly (methyl methacrylate) plates are covered on the box mouth of three rectangle uncovered box bodys respectively.
During work, punching in the ground of detection site or ice face, and by the embedment hole, lower end of supporting steel pipe, protect simultaneously
Card supporting steel pipe is vertical with ground or ice face.Specific works process is as follows: first, and PCB controls infrared emission and receives pipe
Array starts, and infrared emission receives pipe array and thus sends infrared beam array, and infrared beam array is organic through rectangle
It is irradiated to after glass plate on medium (air or accumulated snow), then reflects back into infrared emission reception Guan Zhen through medium (air or accumulated snow)
Row, infrared emission receive photoelectric current that pipe array varies in size according to the formation of the intensity of the infrared beam array reflected (
Infrared emission receives in pipe array, and the height that each infrared emission receives pipe distance ground or ice face is different, is therefore being reflected back
In the infrared beam array come, a part of infrared beam is returned through air reflection, and another part infrared beam is through accumulated snow
Reflecting, the intensity thus causing two parts infrared beam is different, thus causes varying in size of photoelectric current).Then,
The photoelectric current varied in size is converted to the magnitude of voltage varied in size by rectangle PCB, and according to the magnitude of voltage varied in size
Judge draw the separating surface between air layer and snow cover, thus record snow depth value (snow depth value be separating surface with
Distance between ground or ice face).Finally, the snow depth value that three rectangle PCB record respectively is averaged, i.e.
Available high-precision snow depth value.Based on said process, compared with the detection method of existing snow depth, of the present invention
A kind of High Precision Automatic infrared snow feelings detection device by using brand-new structure, it is achieved that the fixed point of snow depth continuously from
Dynamic detection, has thus possessed following advantage: one, compared with the direct method of measurement, the cost of labor of the present invention is lower, labor intensity
Less, and achieve and carry out the most real-time Aulomatizeted Detect in same place.Its two, with ultrasound wave and laser optical method phase
Ratio, the present invention is affected by environment less, and it is measured apart from longer, and is difficult to break down in extreme low temperature environment.Its three,
Compared with video image measurement method, the present invention can accurately reflect out the snow deposit inside generating and vanishing process when melting, and is achieved in
Change to snowmelt runoff carries out Accurate Prediction and forecast.
Present configuration is reasonable, it is ingenious to design, and efficiently solves the detection method cost of labor height of existing snow depth, labor
Fatigue resistance is big, cannot carry out the most real-time Aulomatizeted Detect in same place, affected by environment big, cannot reflect that snow deposit exists
The problem of inside generating and vanishing process during thawing, it is adaptable to the detection of snow depth.
