Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.
Embodiment one：
As shown in figure 1, the full-automatic direct-reading rainfall gauge of the present embodiment includes：Casing 1, collection rain pipe 2, magnetic valve 3, shooting
First 4 and data processing unit 5.
Rain mouthful 11 is held in the top of casing 1 provided with 45 ° of funnel types, in favor of collecting rainwater.
Collection rain pipe 2 is arranged on inside casing 1, and its outer wall is provided with the graduated scale 6 that precision is 1mm.Collecting rain pipe 2 includes internal diameter
It is 200mm, is highly 350mm hypomere body for 200mm epimere body and internal diameter, hypomere body is transparent acrylic
Pipe, has amplification effect, can become apparent from scale after water filling, in favor of imaging.It is additionally provided with collection rain pipe 2 and swims in the water surface
On the thin oilpaper 7 of black, further to improve the definition of scale.
Magnetic valve 3 is arranged on the bottom of casing 1 and connected with collection rain pipe 2, for quantitatively discharging rainwater.
Camera 4 is arranged on the inwall of casing 1, for shooting height of water level image of the correspondence on graduated scale 6.
Data processing unit 5 is arranged on the outer wall of casing 1 and is connected with camera 4 by electric signal, for handling image
Information.
Embodiment two：
As shown in Fig. 2 the udometric rain pipe 2 that integrates of full-automatic direct-reading includes epimere of the internal diameter as 200mm in the present embodiment
Body and internal diameter are 63.2mm, are highly 350mm hypomere body, and other structures are identical with the structure in embodiment one.
Collect the volume V=π R of rain pipe 22H, reality can be calculated according to this formula in drain height h under the same conditions
Apply the proportionality coefficient for collecting rain tube capacity product in example two and embodiment one：
V2/V1=R2 2/R1 2=31.62/1002≈0.1
Therefore, when integrating the internal diameter of the hypomere body of rain pipe 2 as 200mm, the calibration data that camera 4 is read is actual survey
The rainfall obtained, graduated scale precision at this moment is actual 1mm；When integrating the internal diameter of the hypomere body of rain pipe 2 as 63.2mm, shooting
First 4 calibration datas read are multiplied by with proportionality coefficient 0.1, and graduated scale precision at this moment further increases rain equivalent to 0.1mm
The measurement accuracy of gauge.
As shown in figure 3, the udometric operation principle of full-automatic direct-reading is as follows：
Camera 4 with 2 hours be chronomere carry out IMAQ work, storage image information as video backup, and
Current level position is automatically analyzed by data processing unit 5, current rainfall in-position is calculated, then subtract the water before 2 hours
Position data, it is as current 2 hours in rainfall data.Calculate after current rainfall data by GPRS communicating terminals 8 with UDP
The mode of communication is uploaded to host computer 9.
When the water level in collection rain pipe 2 reaches more than 160mm, open magnetic valve 3 and discharge water, magnetic valve 3 is taken the photograph when opening
As first 4 work in every 30 seconds once, current real time water level is read；As water level as little as below 40mm, close magnetic valve 3 and complete draining
Work, this makes it possible to ensure to have enough volumes in collection rain pipe 2 to receive follow-up rainfall.
The minihose plate that data processing unit 5 is produced using LattePanda companies of the U.S., integrated network interface, many USB ports,
WiFi, bluetooth are supported, complete operating systems of Windows 10 are pre-installed, it is built-in a series of to exist comprising Visual Studio, Java
Interior developing instrument, and four core 1.8GHz processors are carried, possess 2/4GB RAM and 32/64GB eMMC and store, it is ensured that it
Operational efficiency and running quality.
Due to directly reading calibration data using camera 4, therefore compared with traditional tilting bucket rain, it can miss reading
Difference is reduced to almost nil.
Full-automatic direct-reading rainfall gauge of the present utility model is combined with master system, with Current Hydrologic management system energy
Enough slitless connections, really realize the automation of artificial rainfall gauge data acquisition.And data processing unit 5 can be stored often automatically
Dial chart picture during secondary data variation, as most directly effective graphical backup information, facilitates user's access, error correction.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
