Description
Technical field
The utility model is related to line measuring system for moisture content in a kind of oil delivering pipe road.
Background technology
As the quantitative analysis of the progress moisture of the development and production technology of scientific research has been cited as all kinds of substance physics and chemistry
One of elementary item of analysis, an important quality index as all kinds of substances.
Different in moisture content in various form sample proposes the different requirements for measuring moisture.Determination of moisture can be with
It is the Quality Identification of industrial control analysis or industrial and agricultural products；Water can be measured from the product counted into ton
Divide also only can carry out water analysis with several microlitres of test solutions in the lab；It can be the constant that water content reaches a few percent to tens
Water analysis or water content are only trace water analysis below hundred a ten thousandths etc..
These Instrument measuring methods are easy to operate, high sensitivity, reproducibility are good, and can METHOD FOR CONTINUOUS DETERMINATION, automatic display data.
External determination of moisture is expensive, is that some laboratories, the enterprise of the country are unaffordable.To strengthen to determination of moisture
Research and practice, achieve fairly obvious benefit, every technology of domestic determination of moisture are made to be drawn close to international level, Neng Gouman
Sufficient common laboratory and the needs of enterprise's production.Classical Moisture Method is gradually replaced by various Moisture Methods,
Including karl Fischer determination of moisture, coulomb determination of moisture, dew point determination of moisture, microwave moisture instrument measure, infrared moisture determination
Deng.

Specific embodiment
With reference to the attached drawing in the utility model embodiment, the implementation process of the utility model is described in detail.
It is as shown in Figure 1 oil pipeline model, material is nonmetallic, and measurement is largely divided into two processes：
First process, as shown in Fig. 2, to determine that 8 transceivers emit signal amplitude phase process.In oil pipeline 1
The middle transmitter 2 for placing a transmitting wideband pulse signal, it is equal with the geometric center circumference of oil pipeline 1 outside oil pipeline 1
The wideband pulse signal that the transmitter 2 that cloth places 8 transceivers 3 of circle to receive in oil pipeline 1 is sent.
Second process, as shown in figure 3, removing the wideband pulse signal transmitter 2 in oil pipeline 1.
Then signal is emitted simultaneously by 8 transceivers 3 outside oil pipeline 2, according to time reversal principle, by receiving
Characteristics of signals adjustment oil pipeline 1 outside place the amplitude-phases of 8 transceivers 3.
If transmitter 2 is located at r0, transmitting signal is P (ω), and the transceiver of surrounding is located at rk, then transceiver transmitting signal
It is determined by formula (1)：
ET(rk, ω) and=P (ω) GF(rk,r0,ω) (1)
Wherein GF(rk,r0, ω) to be preceding to Green's function.
It places a measuring signal transceiver 4 again outside oil pipeline 2 and specially receives signal.
It can must be located at 4 received signal of transceiver at r to determine for formula (2)：
When conveying the oil containing different in moisture, Green's function can change, and change the width that transceiver 4 receives signal
Spend phase.We can obtain this variation with the rule of moisture by testing, and then calculate moisture therein.This
In to moisture measurement when due to oil composition and moisture impurity form difference and the difference of pipeline configuration and size,
The amplitude-phase E (r, t) that similar moisture transceiver 4 measurement during different occasion measurements obtains signal can be variant.Therefore
It needs to need first to measure measured pipeline configuration a series of feelings of known moisture contents before measuring under different occasions, varying environment
Condition is calibrated, and obtains the corresponding table of E (r, t) and water content, is then measured work, is accurately measured and analyzed.
For example, somewhere oil field measures moisture in oil pipeline on land, then first in same structure pipeline
The moisture and oil of identical component are conveyed, the corresponding table of E (r, t) and water content are obtained according to above-mentioned steps, it then can be herein
Ground measures, and water content data are found from obtained E (r, t).
If at sea certain drilling platforms measures moisture in oil pipeline, first conveyed in same structure pipeline
The moisture and oil of identical component obtain another corresponding table of E (r, t) and water content according to above-mentioned steps, then can be
This place measures, and water content data are found from obtained E (r, t).
As shown in Figure 4：Transmitter 2, transceiver 3, the emission principle process of measuring signal transceiver 4 are：Setting amplitude and
Phase and wave memorizer, input microprocessor (MPU), obtain desired signal, then carry out DA conversions, pass through amplifier
(PA) launched with antenna.
As shown in Figure 5：Transmitter 2, transceiver 3,4 record principle process of measuring signal transceiver are：Antenna receives signal
By low noise (LNA) and down coversion is carried out afterwards, then pass through microprocessor (MPU), output amplitude and phase, note after AD conversion
Record amplitude and phase.
The above is only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, in the technical scope that any one skilled in the art discloses in the utility model, the change that can readily occur in
Change or replace, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with
Subject to the protection domain of claims.
