Principle explanation disclosed by the utility model for monitoring the contactless device of drainage pipeline networks flow:
One, under normal operating conditions, the fluid in drainage pipeline 17 is flowed in the form of non-full pipe pressure free current, radar flowmeter
It is contactless with fluid, drainpipe is measured using radar current meter 10 and ultrasonic level gage 11 in a non-contact manner respectively at this time
The flow velocity v of sewage surface in road 17mAnd depth of water h, it is known that underground piping cross-section of river parameter: pipe shape (round tube, rectangle, ladder
Shape etc.), pipe material, that is, roughness (cast iron pipe, UPVC pipe, brick channel etc.), the gradient and silt depth etc..It is flowed with calculating
The method of mechanics establishes 17 Three-dimensional Hydrodynamic mathematical model of drainage pipeline, is calculated and big by computer network numerical value of formatting
The verifying of test data is measured, mean flow rate v of the liquid in drainage pipeline when can get non-full pipeaWith surface velocity vmAnd depth of water h
Between relational expression are as follows: va=f (vm, h), the area S that liquid is through-flowhIt can be calculated by section parameter and depth of water h, then liquid
Instantaneous flow are as follows: Q=va*Sh。
Two, when the liquid of drainage pipeline 17 floods submergence switch 14, it is meant that fluid is that will be filled with pipeline or
It is even overflowed on road surface full of pipeline, radar current meter 10 and ultrasonic level gage 11 will not work at this time, will be by micro process
Device is switched to pressure table mode of operation, only measures the state of liquid level at this time, when liquid level reaches warning liquid level, wireless communication module
It will communicate and alarm with central site frequent progress, and have the function that remind client.Since the impurity in underground piping contains
Amount is uncertain, so will lead to fluid density can change, this brings difficulty to pressure measurement water level, using double difference platen press
Measurement liquid level is come inaccurate, the fundamental formular of differential pressure method that solves the problems, such as level gauging caused by the variation of fluid density are as follows:
Δ P=ρ gH (1)
In formula (1), Δ P is differential pressure value, and H is liquid level, and ρ is fluid density, and g is acceleration of gravity；It can by formula (1)
Know, when surveyed fluid density is constant, proportional relationship can be just presented in differential pressure and liquid level.But the fluid density in underground pipe network
It is difficult to accomplish.The variation of fluid density can seriously affect the accuracy of differential pressure measurement, so that making the precision of level gauging can not protect
Card.It is installed in such a way that two differential pressure pick-ups are by Fig. 1, the difference in height of upper pressure gauge 12 and lower pressure gauge 13 is h, is tested liquid level
Height is H, is then had:
ΔPH=P2-PAtmosphere=ρ gH (2)
ΔPh=P2-P1=ρ gh (3)
In formula (2) and (3), P2For the measured value of lower pressure gauge 13, P1For the measured value of upper pressure gauge 12, PAtmosphereFor atmospheric pressure
The measured value of power table 8 can be obtained by formula (2) and (3):
Liquid level known to formula (4) at this time is only related with two liquid level differences and known distance h surveyed, thus significantly
Reduce fluid density unevenly brought measurement error.The precision of contact liquid level can be effectively guaranteed in this way.
Since complete equipment is powered using battery as power module, in order to meet the needs of long term monitoring,
The power consumption of this equipment is just at key.So this equipment using stage power supply by the way of work, operating mode be every
It powers within 15 minutes once, works on power every time 15 seconds, a hour uploads a data to monitoring center, interval time, work
Time and uplink time can be modified with customer demand as the case may be.Working method is to judge that water level is when just powering on
No to flood submergence switch 14, if not flooding submergence switch 14, radar current meter 10 and ultrasonic level gage 11 work, under
Pressure gauge 13, upper pressure gauge 12 and barometer 8 do not work, and calculate flow.If having flooded submergence switch 14, micro- place
Reason device gets electric signal, then pressure gauge 13, upper pressure gauge 12 and barometer 8 descend to work, and radar current meter 10 and surpasses
Sonic liquid-level meter 11 does not work, and only liquid level is in measuring state at this time, is unable to measure out flow velocity and flow.
Communication antenna 4, radar current meter 10 involved in the utility model, ultrasonic level gage 11, lower pressure gauge 13, on
Pressure gauge 12, submergence switch 14, barometer 8, microprocessor, wireless communication module and power module are all made of existing
Electrical equipment, wherein microprocessor is the minimum system being made of single-chip computer and its peripheral circuit, and wireless communication module uses
GPRS wireless transport module, power module are constituted using battery pack and voltage regulator circuit, lower pressure gauge 13, upper pressure gauge 12 and
Barometer 8 is all made of digital pressure gauge, and the method for used double difference platen press measurement liquid level is in the prior art normal
Rule method, the calculation formula of instantaneous flow are also using existing calculation formula, it is only necessary to carry out simple program to microprocessor
Exploitation can be realized the software design of the application, and the software design and innovative point be not present, and not be that the application is claimed
Content.
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not
It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define
Under the premise of, it can various changes can be made in the form and details to it.
