Work, usually, each component (except solar panel or/and wind-driven generator) may be at dormant state, to save electric energy.
In concrete application, the receiving module of timing receipt Local Weather Report information may be provided for, so as to
Start each component according to rainy situation in weather forecast information to start to work, usually, each component (except solar panel or/
And wind-driven generator) it may be at dormant state, to save electric energy.
In concrete application, rainfall hopper 2 and the runoff rainfall hopper 3 can be in the outer rainfall hopper 1 of woods, woods
It is respectively arranged with solenoid drain valve, solenoid drain valve can be controlled by rainfall metering unit or data acquisition device 4, when rainfall gauge outside woods
When rainfall in graduated cylinder 1, woods in rainfall hopper 2 and the runoff rainfall hopper 3 reaches set amount, data acquisition device 4 can be right
It is recorded, and solenoid drain valve empties rainwater, in order to continuously measure.
It is of course also possible to be not provided with precipitation sensor, receiving module, solenoid drain valve.
The embodiment of the invention also provides a kind of measuring systems for rainfall interception measurement, including above-mentioned one
Measuring device of the kind for rainfall interception measurement further includes data processing programming module 43 and described long-range for receiving
The reception terminal of rainfall continuous data transmitted by wireless communication module 41, receiving terminal can be for computer, mobile phone etc., can be to rain
Amount continuous data is stored, statisticallyd analyze and is drawn, and shows result by display screen.Data in data acquisition device 4
Forest canopy can be calculated according to rainfall data b and runoff rainfall data c in rainfall data a outside woods, woods by handling programming module 43
Rainfall d, rainfall interception amount d are equal to the outer rainfall data a of woods and subtract rainfall data b and Lin Nei rainfall data b, i.e. d in woods
=a-b-c.
Floating is blocked with glass cement by the gap between the U-shaped hose (collecting pipe 31) that trunk is wound and trunk, favorably
Preferably enter hose collection device in trunk runoff, preferably prevents the omission of trunk runoff；Along the U-shaped hose of trunk winding
Opening (width for collecting open slot 310) is moderate, it is therefore prevented that non-trunk intercepting rainwater enters hose；Due to needing to wind, along tree
The U-shaped hose of dry winding is open hour, is converted into spring shape with tiny iron wire and is put into hose, is used to support hose and keeps U-shaped
State prevents trunk intercepting rainwater from overflowing significantly, realizes the trunk runoff of high time resolution, the prison of Interception in canopy
It surveys, the data of available any time realize real-time online and monitor automatically, it is no longer necessary to rain sample with all removing sample every time
Rainfall and run-off are measured, researcher is freed from heavy experiment, is conducive to promote scientific and technological progress and development.
The embodiment of the invention also provides a kind of measurement methods for rainfall interception measurement, using above-mentioned one
Kind is used for the measuring system of rainfall interception measurement, comprising the following steps:
The rainfall metering unit of the measuring system feeds back rainfall hopper 1 outside the woods, rainfall gauge in the woods respectively

Stay rainfall d.
Data processing programming module 43 in the data acquisition device 4 can be according to rainfall number in rainfall data a outside woods, woods
Rainfall interception amount d is calculated according to b and runoff rainfall data c, rainfall interception amount d is equal to the outer rainfall data a of woods and subtracts woods
Interior rainfall data b and Lin Nei rainfall data b, i.e. d=a-b-c.
The data acquisition device 4 passes through long-distance radio communication module 41 for rainfall hopper 1, the Lin Neiyu outside the woods
Meter graduated cylinder 2, the rainfall data of the runoff rainfall hopper 3 and calculated rainfall interception amount d are transmitted to reception eventually
End；
The terminal receives rainfall hopper 1 outside the woods, rainfall hopper 2, runoff rainfall metering in the woods
The rainfall data and rainfall interception amount d of cylinder 3, and above-mentioned rainfall data is stored, statisticallyd analyze and drawn, and is led to
It crosses display screen and shows result, to accomplish that real-time monitoring is synchronous with statistical analysis.
In concrete application, the outer rain gage bucket of multiple (such as 3 or more) woodss and the metering of corresponding rainfall are set outside sample ground
Component monitors the outer rainfall of woods, and rain gage bucket and corresponding is diagonally placed in multiple (such as 3 or more) woodss in sample ground
Rainfall metering unit monitors rainfall in woods, and multiple (such as 3 or more) trunks are arranged on identical or another diagonal line
Runoff device (collecting pipe 31 and corresponding runoff rainfall hopper 3 and rainfall metering unit) is used for real-time monitoring trunk runoff
Amount.Trunk runoff device: the leather hose that a length of 2m diameter is 1cm is broken into 1.5m among hose, forms an a length of 1.5m
U-type groove, and by the S-type winding trunk of hose.The top of winding, will be soft with drawing pin since trunk diameter of a cross-section of a tree trunk 1.3 meters above the ground position (1.3 meters)
Tube top portion is fixed on trunk, stamps drawing pin with the biggish place in trunk gap on the inside of hose then along hose, allows hose
Inside trunk smooth as far as possible.Glass cement is smeared between hose and trunk gap, and is smoothed out, and is leaked out with rainwater-proof from gap, simultaneously
Be conducive to rainwater preferably to enter in hose U-type groove.The rain gage bucket that a good leak tightness with a lid is inserted into the end of hose comes
Measure Stem-flow.Waterproof glass glue is stamped in hose end and rainfall cover contact position, keeps the airtightness of rain gage bucket, and
Rain gage bucket and hose end are tied up on trunk with rope, in order to avoid blown down by strong wind.It goes through S type and is wound in the soft of trunk
Pipe, it is found that have inside and outside a small amount of position hose excessively close to U-type groove opening is smaller, is unfavorable for the drainage of trunk runoff.?
Herein, tiny iron wire can be twined into spring shape to be put into, U-shape state is kept to be used to support hose, conducive to the suitable of trunk runoff
Channel Group is dynamic, prevents trunk intercepting rainwater from overflowing.
