Description

Ultrasonic array energy synthesis probe interface measuring system

Technical Field

The present disclosure relates to an ultrasonic array energy synthesis probe interface measurement system.

Background

Interface measurement of different forms of substances inside existing containers typically requires plug-in measurement equipment.

In addition, in the existing mode, there is a mode of using a single ultrasonic probe, but the single ultrasonic probe cannot accurately detect the interfaces between substances in different forms, and cannot detect the space occupied by the substances in different forms, and meanwhile, as the degree of scaling or hanging materials on the inner wall of the container increases, the single ultrasonic probe can generate a false alarm.

According to one embodiment of the present disclosure, an ultrasound array probe interface measurement system is provided. Fig. 1 shows a view of an ultrasound array probe interface measurement system 10 according to one embodiment of the present disclosure.

As shown in fig. 1, the ultrasound array probe interface measurement system 10 may include an ultrasound array probe 100 and a control device 200.

The ultrasound array probe 100 includes N ultrasound probes, where N ≧ 4, the N ultrasound probes disposed on a wall of the container 20, such as may be affixed on an outer surface of the wall in the present disclosure. The N ultrasonic probes are arranged along the height direction of the container 20, and adjacent ultrasonic probes are spaced by a preset distance. The preset distances may be the same or different. Further, in the present disclosure, the preset distance may be adjusted according to the resolution of the interface measurement, for example, if the resolution requirement of the interface measurement is higher, the preset distance is smaller.

The ultrasonic probe is used to emit ultrasonic waves toward the inside of the container 20, for example, through the outer wall of the container by the ultrasonic probe attached to the outer surface. The ultrasound probe may then receive a return signal generated from the transmitted ultrasound waves.

As shown in fig. 1, the ultrasound array probe 100 may be disposed on only one side of the container 20, wherein each of the ultrasound array probes disposed in this manner is capable of transmitting signals as well as receiving return signals, i.e., is a transceiver-integrated ultrasound probe.

The control device 200 controls the N ultrasonic probes to transmit ultrasonic waves and receive return signals. The N ultrasound probes communicate with the control device 200 through communication lines, wirelessly communicate with the control device 200, and communicate with the control device 200 in a bus format.

Different forms of materials can be contained in the container 20, and an interface is formed between the different forms of materials, and the control device 200 determines the interface position of the interface according to the return signals of at least a part of the N ultrasonic probes. The different forms comprise at least two of gas state, gas-liquid state, solid-liquid state and solid state.

For example, in an alumina settling tank, there may be a supernatant layer (liquid substance), a flocculation layer (solid-liquid substance), and a sludge layer (solid substance). In the present disclosure, three layers are taken as an example for explanation, but the case of two, four or more layers is the same as the principle of three layers, and for brevity, detailed description is omitted in the present disclosure.

The interface between layers will be formed due to the different morphologies of the substances contained in the layers, which can be accurately measured by the ultrasonic probe and the control device in the present disclosure.

For example, as shown in fig. 1, the uppermost layer is labeled 31, the middle layer is labeled 32, the lowermost layer is labeled 22, and the interlayer interface of the uppermost layer and the middle layer is labeled 312 and the interlayer interface of the middle layer and the lowermost layer is labeled 323.

In the present disclosure, at least two ultrasound probes are disposed in the height corresponding to each layer, and the control device 200 determines the interface positions of different morphological substances according to the difference between the return signals of the at least two ultrasound probes disposed in each height space. For example, not only the interface position, but also the height of the space occupied by each form of substance or what form of substance is contained at a certain height of the space, etc. may be measured in the present disclosure.

The control device 200 determines the interface position and/or the height of the space occupied by the different morphologies of material by comparing the difference in the return signals of the N ultrasound probes. Assuming that an interface position is an upper layer substance above and a lower layer substance below, the upper layer substance and the lower layer substance are different morphology substances, the fact that the upper layer substance is contained in a height space corresponding to the upper layer substance is determined by comparing return signals of at least two ultrasonic probes arranged in the height space, and/or the fact that the lower layer substance is contained in the height space corresponding to the lower layer substance is determined by comparing return signals of at least two ultrasonic probes arranged in the height space, and/or the fact that the interface position is determined by comparing return signals of at least two ultrasonic probes arranged in the vicinity of the interface position, or the fact that the interface position and/or the different morphology substances are occupied by the interface position is determined by comparing return signals of an ultrasonic probe group consisting of at least two ultrasonic probes arranged in the height space corresponding to the upper layer substance with return signals of an ultrasonic probe group consisting of at least two ultrasonic probes arranged in the height space corresponding to the lower layer substance The spatial height of (a).

For example, in the case of an alumina settler, the uppermost layer 31 is determined to be a supernatant layer by comparing return signals received by a plurality of ultrasonic probes provided corresponding to the uppermost layer 31, the intermediate layer 32 is determined to be a flocculation layer by comparing return signals received by a plurality of ultrasonic probes provided corresponding to the intermediate layer 32, and the lowermost layer 33 is determined to be a sludge layer by comparing return signals received by a plurality of ultrasonic probes provided corresponding to the lowermost layer 33.

In addition, the interlayer position 312 may be determined by comparing return signals received by an ultrasonic probe group made up of a plurality of ultrasonic probes provided corresponding to the uppermost layer 31 with return signals received by an ultrasonic probe group of a plurality of ultrasonic probes provided corresponding to the intermediate layer 32. The interlayer position 323 can be determined by comparing the return signal received by the ultrasonic probe group constituted by the plurality of ultrasonic probes provided corresponding to the intermediate layer 32 with the return signal received by the ultrasonic probe group of the plurality of ultrasonic probes provided corresponding to the lowermost layer 33. That is, at least two ultrasonic probes arranged in the height space corresponding to the upper layer substance are regarded as an upper ultrasonic probe group, at least two ultrasonic probes arranged in the height space corresponding to the lower layer substance are regarded as a lower ultrasonic probe group, and the interface position between the upper layer substance and the lower layer substance and/or the space height occupied by the substances with different forms are determined by comparing the difference between the return signals of the upper ultrasonic probe group and the return signals of the lower ultrasonic probe group. In addition, the difference between the return signals detected by the probes at the upper layer and the return signals detected by the probes at the lower layer near the interlayer position can be selected to determine the interface position and/or the space height occupied by different morphological substances.

Each ultrasonic probe is provided with a number, an initial installation position and a preset distance. The supernatant layer of the upper layer 31, the flocculation layer of the intermediate layer 32, and the sludge layer of the lower layer 33 formed in the container have different forms. The control device provides control signals for enabling at least two ultrasonic probes in the ultrasonic array probes to simultaneously transmit ultrasonic waves, so that the at least two ultrasonic probes in the ultrasonic array probes simultaneously transmit the ultrasonic waves to the interior of the container, the power integration is carried out on the ultrasonic waves transmitted by the at least two ultrasonic probes in the ultrasonic array probes, the ultrasonic signals with higher power are obtained in the container, and/or the return signals generated by the ultrasonic waves transmitted in the container are simultaneously received by the at least two ultrasonic probes in the ultrasonic array probes, the control device superposes digital signals obtained after analog-to-digital conversion is carried out on the return signals simultaneously received by the at least two ultrasonic probes in the ultrasonic array probes, so that a return signal with higher energy or signal-to-noise ratio is obtained, wherein the control device controls the combination of the at least two ultrasonic probes to be different at different time, the control device can obtain the return signals under different ultrasonic probe combinations at different times, and process and analyze the return signals according to the difference of the return signals to obtain the interface position and/or the space height occupied by different forms of substances, wherein the difference of the return signals is at least one of echo amplitude, amplitude attenuation rate, echo waveform, transceiving time difference and wave impedance. The ultrasonic probes transmit ultrasonic waves and then reach the other side of the wall body of the container after being acted by substances of all layers to generate a type of return signals, the control device 200 receives and processes the type of return signals, and the interface position and/or the space height occupied by the substances in different forms are determined according to the difference of the type of return signals of the ultrasonic probes at different positions, wherein the difference of the type of return signals is at least one of echo amplitude, amplitude attenuation rate, echo waveform, transceiving time difference and wave impedance; or in some cases, different substances in the mixture can rise or settle under the action of the self gravity because of adding the mixture of substances with different forms into the container and/or the stirrer in the container, because the different substances in the mixture have different rising or settling speeds in each layer and/or different particle sizes in each layer, when the ultrasonic waves emitted by the ultrasonic probes act on ascending or descending substances and/or particles with different sizes of substances in each layer, another type of return signal is generated, the control device 200 receives and processes the type of return signal, the interface position and/or the space height occupied by different morphological substances are determined according to the difference of the type of return signals of the ultrasonic probes at different positions, wherein the difference of the types of return signals is at least one of a transceiving frequency difference, an echo amplitude and an amplitude attenuation rate.

In fig. 1, a case where the ultrasonic array probe 100 is provided only on one side of the tank, and each ultrasonic probe is connected to the control device 200 through a communication line is shown, in which case each ultrasonic probe can transmit ultrasonic waves and receive return signals.

Other forms may also be employed in the present disclosure. For example, fig. 2 shows a case where the ultrasonic array probes 100 are provided only on one side of the tank and each of the ultrasonic probes is connected to the communication bus 300 and connected to the control device 200 through the communication bus 300. In fig. 3, the ultrasound array probes 100 are shown disposed on opposite sides of the tank, wherein the ultrasound array probe on one side may be a transmitting ultrasound probe and the ultrasound array probe on the other side may be a receiving ultrasound probe. Although it is shown in fig. 3 that the respective ultrasonic probes are connected to the control device 200 through a bus, they may be connected to the control device 200 through communication lines, respectively, or may be connected to the communication device 200 in a wireless manner.

In addition, under some conditions, such as high temperature conditions, the ultrasonic probe may not be suitable for being directly attached to the wall of the container, and thus may be connected to the wall of the container or to the inside of the container through the cooling sound conduction structure.

In the present disclosure, the control device/sub-control device/main control device determines the interface information according to at least one of the following information of the return signal: receiving and transmitting frequency difference, echo amplitude, amplitude attenuation rate, echo waveform, receiving and transmitting time difference and wave impedance. Wherein the return signal as the measuring signal can be an echo signal generated by transmitting an ultrasonic signal to the other side of the wall body of the container through each layer of materials in the container; the ultrasonic signals can be echo signals generated after the emitted ultrasonic signals are acted by rising or settling substances and/or different-sized particles of substances in each layer, and the action on the ultrasonic signals is different because the falling or rising rates of different substances in each layer are different and/or the sizes of the substance particles distributed in each layer are different; or controlling the ultrasonic waves simultaneously emitted by at least two ultrasonic probes in the ultrasonic array probes, integrating the simultaneously emitted ultrasonic waves to generate echo signals after the action of substances in the container, and/or superposing digital signals generated by the return signals simultaneously emitted by the at least two ultrasonic probes in the ultrasonic array probes after receiving the ultrasonic waves emitted in the container to obtain echo signals with higher energy or signal to noise ratio, wherein the combination of the at least two ultrasonic probes at different moments can be different, and the echo signals under the combination of different ultrasonic probes at different moments can also be different. For example, as shown in fig. 15, the return signals detected by the ultrasonic probe are different for different forms of substances, and in the present disclosure, the situation of the interface position/the substance occupied space, etc. may be detected according to the difference of the return signals.

Further, a transducer, a matching portion, and a cover may be included inside the ultrasound probe. The probe may also have a transformer (signal transformer) and a temperature sensor inside. The control/sub-control/main control can input the high and low range and then output a continuous percentage signal or 4-20mA current signal according to the interface position. The control device/sub-control device/main control device simulates continuous interface positions according to return signals of a plurality of ultrasonic probes of the N ultrasonic probes.

In addition, according to one embodiment of the present disclosure, after the interface location is determined, for a certain form of material, the return signal of the ultrasonic probe is compared with the historical/preset signal of the return signal of the form of material to determine the scaling/bridging inside the vessel wall.

Under the condition of using multiple ultrasonic probes, when the scaling/hanging situation or the scaling thickening/hanging situation inside the wall body of the container changes, the echo of each ultrasonic probe changes to a certain extent, but the difference between the echo signals of the probes of different substances cannot change because the scaling/hanging situation is a common influence. After the interface position is distinguished according to the difference, the change of the echo signal of the ultrasonic probe is not caused by the interface movement, so that the condition that the change of the echo signal is caused by hanging materials or scaling can be determined. The material hanging or scaling condition can be known by recording the waveform formed by the condition of a certain form of substance before the ultrasonic probe and comparing the historical echo signal with the detection echo signal of the ultrasonic probe, and an alarm can be given according to the condition. Under the condition of detecting hanging materials or scaling, the echo waveform information of the ultrasonic probe under a certain form of substance (an upper layer or a lower layer of an interface) at different moments can be recorded.
