Background technology
Runoff silt content in soil erosion is one of important parameter weighing soil erosion, is also water and soil conservation value
Main contents.According to the difference of measuring principle, silt measuring method can be divided into: direct measuring method and indirect derivation method.Base
Runoff and sediment automated monitor in indirect inference method design suffers from the restriction of all many condition, such as power conditions, maintenance
Management, cost etc., these runoff and sediment automated monitors are usually applied to laboratory or the higher region of management level,
The difficulty of field popularization and application is bigger.
Runoff and sediment automated monitor based on direct measuring method design is then largely determined by certainty of measurement with automatic
Change level, the runoff and sediment automated monitor as currently utilized hydrometer method to design has used small-sized runoff bottle or bottle of weighing in a large number
As carrying tool, its measurement error is relatively big, and the most easily deposits, and is not easy to management and safeguards;Major part runoff and sediment simultaneously
Automated monitor need stirring or pumping equipment, electric power energy supply is proposed higher requirement, these the most all limit its
The application of remote districts.
If patent 201510121355.0 is based on two hydrocone type water inlet mixings, and small-sized bottle of weighing is utilized to weigh,
This equipment easily deposits, and there is certain restriction in maintenance management;Patent 201410232617.6 make use of motor driven,
With automatic sampling and measure multi-level run-off and quantity of sand and mud, but quantity of sand and mud can be measured and needs to stop water inlet, and measure silt from
Dynamicization degree is low, which has limited it and uses in the wild, and patent 201520151152.1 enters after make use of No. three siphoning installations and claims
Weight bottle, and employ cantilever type weighing sensor and weigh, using impeller counting calculated flow rate, structure constraint is in bottle of weighing
Size and the impact of current momentum LOAD CELLS cannot be reduced, there is certain error, when unmanned, reliability has
Limit.
To sum up, so far, there is techniques below in the equipment design automatically monitored for field soil erosion runoff and sediment
Problem: (1) wild environment is severe, unmanned, device structure complexity not easy care, service life is short, automaticity is low, accurate
Really property and poor stability;(2) needing motor or motor, energy consumption is high, power supply difficulty, manufacturing cost increase;(3) runoff is by entering
Skewness when mouth is passed through in cylinder, impact liquid level, cause water level signal and weight signal to gather inaccurate.(4) equipment is easy
Shoal materials, after completing an interim monitoring, the fully emptying of silt becomes problem, so that measures is accurate next time
Property decline.(5) due to unmanned, therefore this equipment must adapt to field work requirement, meet whole-process automatic operation, analysis and
The function of transmission.
Summary of the invention
The invention aims to solve above-mentioned technical problem, it is provided that a kind of structure extremely simple reliable, easy and simple to handle,
Energy consumption is low, automaticity is high, sand-flash effect is good, accuracy is high, produce and the low field runoff and sediment of maintenance cost is supervised automatically

The most significant end stating slope shape water storage base plate flushes, existence based on slope shape water storage base plate, setting of the water level probe of extreme lower position
Meter position can not be too low, if being less than the most significant end of slope shape water storage base plate, then and the accuracy that may be gathered by influence to sediment, also
It is unfavorable for calculating;Further, when only one water level probe, also can make water level in storage flow chamber less than slope shape water storage base plate
High-end, cause cannot slope shape water storage base plate being formed and effectively wash away.(4) water intaking valve and outlet valve are controlled by valve positioner
Opening and closing, described valve can use the valve of the quickly response such as such as electromagnetic valve.Whole control process can pass through single-chip microcomputer control
System, truly realize unattended automatization.(5) single-chip microcomputer is utilized to gather water level signal through water level probe, through claiming
Weight sensor collection storage flow chamber in weight signal, through timer record arrive a certain water level time, combine known to other
Data, can realize computational analysis in single-chip microcomputer, obtain target data, and realize data biography by remote-wireless communication unit
Defeated;(6) not using motor or motor in whole equipment, while automatization, energy consumption control is extremely low, can use storage battery power supply,
Further, also can connect wind and solar hybrid generating system provides electric energy to accumulator, meets the various requirement of field work, adapts to
The adverse circumstances of field work.
Use the said equipment to field soil erosion runoff and sediment automatic monitoring method, comprise the following steps:
(1) controlling to open water intaking valve, the footpath that runoff water inlet pipe flows into flows through water intaking valve and flows into the storage flow chamber in cylinder, works as water
Visited meter sensing by this water level when position arrives the water level probe of extreme lower position, send a signal to single-chip microcomputer, when controlling timer record
Between t1, LOAD CELLS gather weight M1;Controlling water intaking valve to close, outlet valve is opened, and is discharged by the liquid in cylinder simultaneously;
