Technical field
The present invention relates to meteorological phenomena measurement device field more particularly to a kind of high-precision Waterwheel-type rainfall gauge and measurement sides
Method.
Background technology
The Nature rainfall has dual character, it is possible to give blessings, it is also possible to make misfortune；Plentiful rainwater can provide for crops
Better growing conditions, and the disasters such as flood, landslide and mud-rock flow may at most be led to by crossing, if excessively few then easily cause
Arid causes the puzzlement of domestic water, field irrigation and service water when serious, even result in soil salt routedization and desertification
Phenomenon.Therefore, reinforcement is mankind's prediction to the research of meteorologic phenomena, prevents the most effective approach of living environment situation, accurately
It is an important mission that era development proposes the mankind to measure the amount of rainfall.
On October 30th, 2014, China Meteorological Administration issues《National weather innovative project in science and technology（2014-2020）Embodiment party
Case》, it is proposed that climatic prediction and climate system model are clear as one of the three big tackling key problem tasks for realizing weather service modernization
Demand to rainfall forecast.Rainfall refers within the unit interval, is not evaporated on unit area, does not permeate and do not flow
Lose and the height of accumulated rain water, unit are millimeter, be one of most basic index in meteorological observation parameter.It can intuitively indicate
The number of rainfall, receives the concern of each application industry.In real time, the accuracy and reliability for looking forward or upwards rainfall product data in advance is anti-in flood prevention or control
Particularly critical impulse is played in drought, Monitoring of drought and industrial and agricultural production.Meanwhile rainfall product data is also pre- to weather
Report, climatic analysis and meteorological research provide important infrastructure service, therefore the high-acruracy survey of rainfall and measurement functional experience
With important research significance.
Rainfall gauge is of all kinds both at home and abroad at present, generally towards intelligent and miniaturization, with microprocessor into
Row acquisition, is calculated and is controlled analysis, and some additionally provides the functions such as data remote transmission, early warning and alarm.Common rainfall gauge
With two kinds of tipping bucket type and Weighing type for mainstream, tipping-bucket rain-gauge is by the tipping bucket of mechanical double-steady-state property, when rainfall to one
When quantitative, change tipping bucket equilibrium state, overturn, finally fall into weighing hopper；Weighing type rain gauge is from top to bottom set successively
Set and contain rain device, tipping bucket and heavy device, the weight change of pan of a steelyard is calculated using pressure sensor come calculate rainfall number.Research
Personnel explore from various dimensions such as the usage experience of equipment, applicability and process structures for many years, constantly upgrade.Such as
Patent ZL201410462385.3 provides a kind of high-resolution tilting bucket rain device with error correction function, can be right
0.1mm tilting bucket rains are corrected when measuring fructufy；Patent ZL201410783249.4 is real-time using tipping-bucket rain-gauge
The method for measuring rainfall intensity, is installed in rainfall measured zone and initializes systematic parameter by tipping-bucket rain-gauge, solve
Tipping-bucket rain-gauge calculates the problem of the accuracy and real-time difference of raininess, and it is real-time in needs such as traffic to be conducive to the type rainfall gauge
The industry or field high volume applications that raininess measures；Patent ZL201510358877.2 devises one kind and measuring various intensity in real time
The sensor type rainfall gauge of rainfall, it is small, it is simple and convenient, structure design can guarantee the various intensity rainfalls of high-acruracy survey and
The integrality and continuity of rainfall data record, intuitively reflect real-time rainfall and rainfall variation tendency；Patent
ZL201720883882.X discloses a kind of weighing type rain gauge, relative to traditional structure, can significantly reduce rainwater and enter storage
Whereabouts momentum when water installations makes it symmetrically not interfere again.These ways and means largely improve
Accurately measuring for rainfall, also achieves intelligent management, has reached good sector application effect.Since tipping bucket is mechanical movement
Mode, inevitable rainwater splashes out loss part rainfall in switching process, in addition, when raininess is excessive, it may occur that tipping bucket has little time to turn over
The case where turning, this may cause the further expansion of error, need to inspect periodically in, remove funnel, sieve and shovel
Clast in bucket and dirt also need periodically to recalibrate；Technical need also has some expectations to the rainfall gauge precision of Weighing type, and
Imported product is at high price, it is difficult to universal.Therefore, the development of high-precision measurement method and technique study for rain gauge
Important in inhibiting.
