Embodiment eight：
The present embodiment is a kind of continuously to be taken using the water and soil conservation value cell runoff and sediment of above-described embodiment described device
The step of sample measuring method, the method, is as follows：
（One）The step of parameter setting：By the downstream of sampling and measuring device installation outdoor cell slope surface, sample bucket water is set
Position height, observing frequency parameters.Due to being automated system, it is to need to be installed according to surrounding environment in installation, keeps away
Exempt from excessively humidity, physical features is too low and is submerged, and wind-force excessive cannot influence sampling and measurement.
（Two）The step of storing electric energy：There is sunlight weather, solar panel is collected solar energy, deposited after being converted to electric energy
At this moment storage controls sub-device to be in the few resting state of power consumption in storage battery.It is best due to being completely self-contained system
Using self-centered power-supply system, the energy is such as obtained by solar energy, or the energy is obtained by wind-force, is stored in storage battery
In.
（Three）The step of wake-up：When rainfall starts, the rainfall sensor wakes up control sub-device, controls sub-device quilt
Establish and contact with remote management center after wake-up；Meanwhile water-collecting tray starts to collect rainwater, is stored in after filtering standby in water tank
With.
For save the energy, in the case of no rainfall, whole device should be at resting state, except rainfall sensor it
Outside, other equipment is all stopped, and in particular for the control sub-device of continuous power consumption, therefore, wakes up and passes when rainfall occurs
Sensor sends signal, and control sub-device is waken up, and after control sub-device wakes up, starts to be controlled whole device, starts work
Make, while net connection is established with remote management center, notice remote management center rainfall starts, and will enter sampling and measurement
Work.
（Four）The step of sampling and measurement rainfall：When cell produces runoff, preliminary survey water-level gauge is with the frequency of at least 50 times/second
The water level in sample bucket is measured, sub-device start recording water outlet contributing time timing is controlled, when the water level in sample bucket reaches
During setting value, control sub-device stops timing and drives annular sampling crawler belt to rotate, and next sample bucket is entered under sample tap
Side, samples into next round, so moves in circles, and control sub-device constantly records sampling number and the water outlet production of sample bucket
The time is flowed, as metering run-off, the foundation of silt content, and is in long-distance management system by these data sendings.
The process of sampling must be very accurate, therefore, the water in measuring sample bucket by water-level gauge when sampling
Position, once having reached desired height, leaves startup sampling annular sampling crawler belt, replaces the sample bucket of water intaking.Due to sample bucket
In water and quantity of sand and mud by accurate measurement below, therefore, as long as the number that metering sample bucket is replaced, it is possible to accurate to calculate
Go out run-off.
Setting value is a pre-set water level value, and normal water place value is more lower slightly than the height of sample bucket, can thus make
Water level after sampling in sample bucket is slightly below the upper limb of sample bucket, sample can sufficiently stable reservation fallen in sample bucket,
It will not be shaken out because of moving for sample bucket in sample bucket.But this water level value can not be too low, too low, influences sampling efficiency,
Generally highly it is advisable in the sample bucket of 80-90%.
Sample and measurement process in, control sub-device constantly records measurement data, and by these data storages, at the same time
Remote management center is sent data to, can also will be transmitted to remote management center after data summarization after rainfall, to save
Internet resources.
（Five）The step of accurate measurement：After sampler barrel water intaking, accurately measured in next stop position：Control first
The two-dimensional code reader of device reads the Quick Response Code that the sampler barrel weight is carried on sampler barrel, while annular sampling crawler belt declines,
Sampler barrel is set to fall in orbit, the ultrasonic vibrator on track carries out vibration of ultrasonic wave to sampling water, to exclude the sky in water
Gas, and the bulk soil that water sample is brought is crushed, after vibrations, weighing sensor weighs sampler barrel, after removing sampler barrel weight
Obtain accurately sampling weight, the sample bucket depth of water and accurate sampling weight of control sub-device record and storage repetition measurement, concurrently
Send to remote management center.
For the accurate water and silt weight weighed in sample bucket, it is necessary first to remove the weight of sample bucket in itself, take
Sample bucket in itself after sample bucket is cleaned weigh in advance by middle weight, can so ensure, even if there is residue in sample bucket
Silt do not clean out, its weight will not influence to wash measurement accuracy once.When annular sampling crawler belt is fallen, annular
Grab on sampling crawler belt is not undertaking the weight of sample bucket, and the total weight of sample bucket falls on track, shaking on track
Dynamic device starts to shake, and the bulk silt in water is shatter, water and silt is uniformly mixed, is at this moment weighing, it is possible to ten
Divide and accurately obtain the weight of water and silt.Accurate repetition measurement is carried out to the water level in sample bucket after weighing, since ultrasonic wave shakes
It is dynamic, the bulk soil in water is crushed, is uniformly mixed silt and water, in other words by level measuring condition one in each sample bucket
Causeization, is so more advantageous to accurately calculating the parameters of sample.
The calculation formula of water and silt weight in sample bucket：
The water and silt sample cumulative volume obtained according to depth of water h1 calculating in sample bucket：
During h1≤h2：VAlways=3.14×h2×（D2/2）2
During h1 ＞ h2：VAlways=3.14×h2×（D2/2）2 + 1/3 π (h1-h2) (（D1）2+（D2）2+D1×D2)/4
According to sample bucket+water sample quality mAlwaysAnd mBucketThe water and silt sample gross mass m that calculating obtainsSample：
mSample=mAlways- mBucket
Silt content is calculated according to formula：
SIt is husky=γIt is husky/ VAlways× (mSample- γWater× VAlways) /(γIt is husky- γWater)
Wherein：SIt is huskyFor silt content, γIt is huskyFor the silt cumulative volume in sample bucket, γIt is huskyAnd γWaterThe respectively appearance of silt and water
Weight.
（Six）The step of cleaning：Sampler barrel enters cleaning area along annular sampling crawler belt, opens sampler barrel bottom valve, releases
Water and silt in sampler barrel, retractable vibrations ring are clamped sampler barrel and are shaken, and open the rainwater that flushing pump extracts storage, nozzle
Sampler barrel is cleaned in stretching, and sampler barrel continues to move ahead with annular sampling crawler belt after cleaning, prepares next sub-sampling.
Water level in water tank is also a highly important parameter, if not having water in water tank, its cleaning can not
Complete, sampling work can not also be completed, and therefore, if not having water storage in water tank, control sub-device should stop sampling.
（Seven）The step of stopping：After rainfall, rainfall sensor sends the signal of rainfall stopping, and control sub-device enters
It is standby, working status is again introduced into if continuing to rain, if several hours do not have rainfall, into resting state, if
There is sunlight appearance, then into charged state.
When rainfall stops, since runoff has hysteresis, control sub-device is not stopped, simply when preliminary survey water level
Meter, when detecting that the water level in sample bucket can not reach the water level of setting, controls sub-device break-off, whether wait continues to drop
Rain, if the stand-by period is longer, control sub-device is again introduced into resting state.
