Description

Technical Field

[0001] This disclosure relates to the technical fields of industrial measurement, and in particular to a composite medium layered interface measurement system and method. Background Technology

[0002] In some industrial production processes, it is necessary to know the interface / boundary location of different media (such as mud layer, mud-water mixture layer, clear liquid layer, etc.) in containers such as tanks.

[0003] Existing technologies typically employ methods involving immersing measuring instruments in a medium to detect its physical parameters (such as density and temperature). Immersion measuring instruments, such as submersion thermometers and submersion buoyancy balls, determine the stratification of the medium based on information such as temperature and buoyancy at different depths. However, after prolonged use, the probe surfaces of these measuring instruments are prone to scaling and corrosion, which significantly affects the measurement results.

[0004] Existing technologies also include solutions for detecting media stratification through external attachment (such as attaching temperature sensors or vibration wave generating devices to the outer wall of the container). This addresses the shortcomings of submersible measuring instruments, where the probe directly contacts the medium, leading to easy scaling and corrosion on the probe surface. However, for containers of different materials, after a period of use, externally attached measuring instruments may experience corrosion or scaling on the inner wall of the container due to the influence of the internal medium. In such cases, the media stratification information detected by the externally attached measuring instrument will have significant errors, greatly affecting the measurement results.

[0005] Therefore, how to effectively and accurately detect the stratification of a medium is a technical problem that urgently needs to be solved. Summary of the Invention

[0037] Figure 1 This is a schematic block diagram of a composite media layered interface measurement system according to one embodiment of the present disclosure.

[0038] refer to Figure 1 The composite medium layering interface measurement system 1000 of this embodiment includes:

[0039] An immersion measuring device 100 is used to be installed inside a container to obtain first stratification information of the medium inside the container.

[0040] An external measuring device 200 is installed outside the container to acquire second layer information of the medium inside the container.

[0041] The control device 300 is used to generate a correction amount based on the difference between the first layer information and the second layer information, and to correct the second layer information based on the correction amount to obtain the corrected second layer information.

[0042] In some embodiments of this disclosure, the immersion measuring device 100 performs an immersion / extension action based on motion control parameters to measure the medium inside the container and obtain first stratification information of the medium inside the container.

[0043] The control device 300 can generate or adjust motion control parameters based on the first layer information and / or the second layer information; or the motion control parameters can be preset by the control device 300.

[0044] The composite medium layered interface measurement system disclosed herein includes motion control parameters including one or more of the following: insertion / extension rate, insertion / extension depth, and insertion / extension frequency.

[0045] In some embodiments of this disclosure, the immersion measuring device 100 is disposed inside the container, capable of immersing a medium and measuring the medium characteristic information of the immersion area, obtaining the medium characteristic information of the immersion area, and obtaining first layering information based on the medium characteristic information;

[0046] The external measuring device 200 is installed outside the container and can measure the outer wall area of ​​the container from the outside of the container to obtain the feature information of the outer wall area and obtain the second layer information based on the feature information of the outer wall area.

[0047] In other embodiments of this disclosure, the immersion measuring device 100 is disposed inside the container and is capable of immersing a medium and measuring the medium characteristic information of the immersion area to obtain the medium characteristic information of the immersion area.

[0048] The external measuring device 200 is installed outside the container and can measure the outer wall area of ​​the container from the outside of the container to obtain the feature information of the outer wall area;

[0049] The control device 300 can determine the medium stratification information inside the container, i.e., the first stratification information, based on the medium characteristic information of the input area, and can determine the medium stratification information inside the container, i.e., the second stratification information, based on the characteristic information of the outer wall area.

[0050] Continue to refer to Figure 1 Preferably, the immersion measuring device 100 is installed inside the container, which can immerse the medium and measure the medium's characteristic information to obtain the medium's characteristic information;

[0051] The external measuring device 200 is installed outside the container and can measure the outer wall feature information of the container from the outside of the container to obtain the outer wall feature information;

[0052] The control device 300 can determine the first layering information of the medium inside the container based on the measured medium characteristic information, and can determine the second layering information of the medium inside the container based on the measured outer wall characteristic information.

[0053] The control device 300 can generate a correction amount based on the difference between the first layer information and the second layer information, and correct the second layer information based on the correction amount to obtain the corrected second layer information.

[0054] The containers described in this disclosure can be various containers used to hold media (liquid, solid, solid-liquid mixture, etc.), and the container can be cylindrical, cuboid, or other shapes.

[0055] The immersion measuring device 100 disclosed herein may adopt the immersion layer analysis device (including signal detection unit, immersion device, processing device, and power module) or similar structure as described in the applicant's prior patent application CN2022100643369, or the liquid interface position microwave measuring device or similar structure as described in the applicant's prior patent application CN2022107977290, or other types / structures of immersion measuring devices in the prior art, all of which fall within the protection scope of this disclosure.

[0056] The external measuring device 200 can measure the outer wall feature information in real time to determine the stratification information of the medium inside the container.

[0057] The external measuring device 200 disclosed herein may employ the vibration wave layering interface measuring device or a similar structure as described in the applicant's prior patent application CN2021111091057, or the medium layering interface measuring device or a similar structure as described in the applicant's prior patent application CN2023116420420, or other types / structures of external measuring devices in the prior art, all of which fall within the protection scope of this disclosure.

[0058] The control device 300 disclosed herein can be a portable device (such as a tablet computer, laptop computer, etc.), a host computer, etc., and can realize the functions of the control device 300 by executing software programs.

[0059] In this disclosure, the media layering information includes the thickness of each media layer and / or the location of the layering interface in the vertical direction.

[0060] The aforementioned correction amount can be the difference between the layer interface position in the first layer information and the layer interface position in the second layer information. For example, if the layer interface position between the clear liquid layer and the solid-liquid mixture layer in the first layer information is A, and the layer interface position between the clear liquid layer and the solid-liquid mixture layer in the second layer information is B, then the correction amount is C=|AB|.

[0061] The aforementioned correction amount can also be the difference between the thickness of the clear liquid layer (or solid-liquid mixture layer or solid layer) in the first layer information and the thickness of the clear liquid layer (or solid-liquid mixture layer or solid layer) in the second layer information.

[0062] The composite media layered interface measurement system 1000 disclosed herein, by configuring the aforementioned control device 300, can generate a correction amount based on the difference between the first layered information (obtained based on the submersible measurement device 100) and the second layered information (obtained based on the external measurement device 200), and correct the second layered information (obtained based on the external measurement device 200) based on the correction amount to obtain the corrected second layered information.

[0063] Since the probe of the submersible measuring device 100 has high accuracy in the early stage of use and is easier to clean than the inner wall of the container, the composite media layering interface measurement system 1000 of this disclosure, by combining the submersible measuring device 100 and the external measuring device 200 (e.g., an externally attached measuring device), can correct the media layering information obtained by the external measuring device 200 based on the media layering information obtained by the submersible measuring device 100 in the early stage of the composite media layering interface measurement system 1000, thereby improving the measurement accuracy of the composite media layering interface measurement system 1000 by improving the measurement accuracy of the external measuring device 200.

[0064] With the use of the composite media layering interface measurement system 1000, when the probe of the submersible measurement device 100 needs to be cleaned or replaced, media layering information can be obtained based on the external measurement device 200 of the composite media layering interface measurement system 1000.

[0065] The composite media stratification interface measurement system 1000 disclosed herein can measure media characteristic information at multiple different or continuous locations within a container via an immersion measuring device 100. Since the outer wall characteristic information used to determine media characteristic information / media stratification information can be measured in real time via an external measuring device 200, the immersion measuring device 100 can perform periodic measurements, reducing the frequency of media being introduced into the container, reducing the possibility of probe scaling, and extending the probe's service life.

[0066] Based on the composite medium layering interface measurement system 1000 disclosed herein, the medium layering situation can be comprehensively judged based on the aforementioned first layering information and second layering information, thereby improving the accuracy of the medium layering situation judgment.

[0067] Uneven scaling on the inner wall of the container can affect the measurement information (outer wall feature information) of the external measuring device 200, causing measurement deviations. The medium feature information measured by the submersible measuring device 100 can be used to correct the outer wall feature information, thereby making the medium stratification information obtained based on the external measuring device 200 more accurate.

[0068] The external measuring device 200 is not sensitive to the measurement of mud layers. The composite medium layer interface measurement system 1000 disclosed herein can use the medium characteristic information obtained based on the submersible measuring device 100 to calibrate or correct the outer wall characteristic information of the external measuring device 200, thereby improving the measurement accuracy of the external measuring device 200 on the mud layers.

[0069] The composite media layering interface measurement system disclosed herein can achieve precise positioning of the media layering interface: the external measurement and the media layering information (e.g., mud layer position) measured are consistent, verifying the accuracy of the external device (i.e., external measuring device) in measuring the media layering information (e.g., mud layer).

[0070] Provided that the external measuring device 200 can obtain reliable mud layer data, the submersible measuring device 100 may not need to measure the mud layer; or, the submersible measuring device 100 may not be submerged too deeply in the medium to avoid penetrating into turbid or mud layers that are more likely to cause probe scaling; and since the external measuring device 200 can obtain accurate measurement results, the time that the submersible measuring device 100 spends in the medium layer (such as mud layer) can be shortened, which can reduce probe scaling / corrosion, extend maintenance cycles, extend probe lifespan, reduce failures and manual cleaning, and avoid the risk of the probe being dragged away by the rake.

[0071] The external wall feature information described above may include temperature values ​​at different locations in the vertical direction (the height of the container), or vibration signal feature values ​​(vibration signal intensity, vibration signal frequency, vibration signal attenuation rate) at different locations in the vertical direction.

[0072] The medium characteristic information described above may include at least one of the following at different locations in the vertical direction: temperature, density, concentration, transmittance, particle size, conductivity, and capacitance.

[0073] Those skilled in the art, inspired by the technical solutions disclosed herein, can select / adjust the measured medium characteristic information and outer wall characteristic information, all of which fall within the protection scope of this disclosure.

[0074] In some embodiments of this disclosure, the immersion measuring device 100 of the composite medium layering interface measurement system 1000 of this disclosure measures the medium inside the container based on motion control parameters to obtain medium characteristic information; the external measuring device 200 measures the outer wall characteristic information of the outer wall of the container in real time to obtain outer wall characteristic information.

[0075] Preset motion control parameters can be configured in the control device 300. Control software 301 can be configured within the control device 300, and the motion control parameters can be configured or modified / adjusted based on the control software 301. The control software 301 executes control of the immersion measuring device 100 based on the motion control parameters.

[0076] Since the external measuring device 200 of this disclosure can measure the outer wall feature information used to determine the stratification information of the medium inside the container in real time, the submersible measuring device 100 does not need to continuously measure the medium feature information, but can perform measurements periodically (e.g., by setting multiple interval measurement cycles), thereby reducing the frequency / duration of the probe of the submersible measuring device 100 being immersed in the medium inside the container, reducing probe scaling / probe corrosion, and extending the probe's service life.

[0077] Motion control parameters can be control parameters such as insertion rate and insertion depth used to control the insertion measuring device 100.

[0078] In some embodiments of this disclosure, the control device 300 of the composite medium layered interface measurement system 1000 generates or adjusts motion control parameters based on second layered information (obtained based on external measuring device 200) and / or first layered information (obtained based on immersion measuring device 100).

[0079] The motion control parameters may include one or more of the following: injection rate, injection depth, and injection frequency (injection cycle).

[0080] Submission rate: The control device 300 controls the submersible measuring device 100 to accelerate or rapidly enter the clear liquid layer to detect the medium characteristic information of the clear liquid layer according to the second layer information and / or the first layer information, and controls the submersible measuring device 100 to decelerate or slowly enter the solid-liquid mixed layer or turbid layer to detect the medium characteristic information of the solid-liquid mixed layer or turbid layer; for mud layer or solid layer, an early warning can be given, so that the probe of the submersible measuring device 100 slowly moves to the target position / depth, thereby accurately measuring the interface position between the turbid layer and the solid layer.

[0081] Frequency of input / output: The control device 300 controls the frequency of input / output of the medium by the input / output measuring device 100 according to the second layer information and / or the first layer information. If the difference between the second layer information and the first layer information is small (within the preset difference range), the frequency of input / output of the medium is reduced or decreased to reduce the possibility of probe scaling / probe corrosion and improve probe service life.

[0082] The input frequency or input cycle (the principle is the same as the input frequency) can be set according to the needs of the industrial scenario or measurement experience to obtain the corresponding first layer information (i.e., the layer information obtained based on the input measurement device 100).

[0083] Figure 2 This is a schematic block diagram of a composite medium layered interface measurement system 1000 according to one embodiment of the present disclosure.

[0084] refer to Figure 2 In this embodiment, the control device 300 may be equipped with a container inner wall scar determination module 302, which may be in the form of software.

[0085] Figure 3 This is a schematic diagram of the process of a container inner wall scar determination module 302 performing a container inner wall scar determination according to one embodiment of the present disclosure.

[0086] The container inner wall scaling determination module 302 is used to perform:

[0087] S3011. Determine the difference value between the second layer information and the first layer information;

[0088] S3012. Compare the difference value of the layered information with the threshold for judging the scaling of the inner wall of the container to obtain the comparison result;

[0089] S3013. If the comparison result shows that the difference in layered information is greater than or equal to the threshold for determining the scaling of the inner wall of the container, then it is determined that scaling has occurred on the inner wall of the container.

[0090] The container inner wall scaling determination module 302 can also be used to perform:

[0091] S3014. If the comparison result shows that the difference in layer information is less than the threshold for determining the crusting on the inner wall of the container, then the crusting phenomenon on the inner wall of the container is not determined.

[0092] The second layer information and the first layer information may both include the thickness of each medium layer and / or the position of at least one layer interface in the vertical direction, and this disclosure does not impose any particular limitation on this.

[0093] Figure 4 This is a schematic block diagram of a composite media layered interface measurement system 1000, which is another embodiment of this disclosure.

[0094] refer to Figure 4 In this embodiment, the control device 300 further includes a correction amount generation module 303, which generates or does not generate the correction amount described above based on the determination result of the container inner wall scaling determination module 302.

[0095] In some embodiments of this disclosure, if the container inner wall scaling determination module 302 determines that scaling has occurred on the container inner wall, the correction amount generation module 303 of the control device 300 generates a correction amount.

[0096] By using the container inner wall scaling determination module 302, the control device 300 of this disclosure can generate the correction amount described above only when scaling occurs on the container inner wall. If no scaling occurs on the container inner wall, the medium stratification situation can be judged based on the first stratification information and the second stratification information described above, without having to generate a correction amount to correct the second stratification information.

[0097] Figure 5 This is a schematic block diagram of a composite media layered interface measurement system 1000, which is another embodiment of this disclosure.

[0098] refer to Figure 5 In this embodiment, the composite medium layered interface measurement system 1000 further includes an early warning device 400, which is communicatively connected to the control device 300.

[0099] The control device 300 may also include a warning information generation module 304, which generates or does not generate warning information based on the judgment result of the container inner wall scaling judgment module 302.

[0100] When the container inner wall scaling determination module 302 determines that scaling has occurred on the container inner wall, the warning information generation module 304 generates warning information, and the control device 300 transmits the warning information to the warning device 400. The warning device 400 outputs the warning information, which can be done by voice broadcasting. This disclosure does not make any special restrictions on this.

[0101] In other embodiments of this disclosure, the control software 301 of the control device 300 can change the motion control parameters for controlling the submersible measuring device 100 multiple times, and control the submersible measuring device 100 to measure medium characteristic information multiple times based on the multiple changes in motion control parameters.

[0102] The control device 300 obtains the first layer information based on the medium characteristic information measured multiple times (for example, by averaging multiple measurements to obtain the first layer information).

[0103] The control device 300 determines the difference value of the layer information (e.g., the difference value of the interface position) based on the first layer information and the second layer information and generates a correction amount for correcting the second layer information.

[0104] Therefore, the composite medium layered interface measurement system 1000 disclosed herein can analyze the measurement characteristics of the external device (i.e., the external measuring device 200) in reverse based on the known information of the "interface between two media" accurately positioned by the immersion measuring device 100, thereby clarifying the error of the measurement characteristics of the external measuring device, thereby enhancing the anti-interference ability of the external device against interference factors such as scabs, and further improving the measurement accuracy of the external measuring device.

[0105] Since the formation of scale on the inner wall of the container can cause errors in the second layer information obtained by the external measuring device 200, the first layer information obtained by the submersible measuring device 100 is mainly relied upon. The first layer information is used to correct (compensate or calibrate) the second layer information determined by the external measuring device 200, thereby improving the measurement accuracy of the external measuring device 200.

[0106] In some embodiments of this disclosure, preferably, the control software 301 can automatically perform multiple changes to the motion control parameters based on the determination result of the container inner wall scar determination module 302, thereby obtaining more accurate first layer information and further obtaining more accurate correction amount to correct the second layer information.

[0107] For the composite medium layered interface measurement system 1000 of the various embodiments described above, the outer wall feature information and the medium feature information can be the same type of feature information, for example, both can be temperature values.

[0108] In some other embodiments of this disclosure, the control device 300 of this disclosure can determine the degree of scaling on the inner wall of the container based on the layering information difference value or the correction amount described above.

[0109] In summary, the composite media layered interface measurement system disclosed herein can achieve "accurate measurement of external equipment → precise deployment of external equipment → reduction of probe scaling + optimization strategy → inverse analysis of the accuracy of external equipment measurement characteristics → more accurate measurement of external equipment", forming a closed-loop optimization and improving measurement efficiency and accuracy.

[0110] Based on the composite medium layering interface measurement system described above, refer to Figure 6 This disclosure also provides a method M400 for measuring media layering interfaces, comprising:

[0111] S402. Obtain the first stratification information of the medium inside the container based on the submersible measuring device;

[0112] S404. Obtain the second layer information of the medium inside the container based on an external measuring device;

[0113] S406. Based on the first layering information, the second layering information is corrected to obtain the corrected second layering information.

[0114] refer to Figure 7 This illustrates a media layering interface measurement method M500 according to yet another embodiment of the present disclosure, comprising:

[0115] S502. Obtain the first stratification information of the medium inside the container based on the submersible measuring device;

[0116] S504. Obtain the second layer information of the medium inside the container based on an external measuring device;

[0117] S506. Determine the difference value between the second layer information and the first layer information;

[0118] S508. Compare the difference value of the layered information with the threshold for determining the scaling of the inner wall of the container to obtain the comparison result;

[0119] S510. If the comparison result is that the difference value of the layer information is greater than or equal to the scarring determination threshold of the inner wall of the container, then it is determined that the inner wall of the container has a scarring phenomenon.

[0120] Based on the media stratification interface measurement method disclosed herein, it is possible to accurately measure the location of the stratification interface of the media within a container, detect scaling phenomena on the inner wall of the container, correct the measurement results, extend the service life of the immersion measurement device, and provide scaling early warning. This provides an efficient and reliable solution for media stratification interface measurement in industrial scenarios.
