Description

Technical Field

[0001] This invention relates to the field of sensor probe technology, and specifically to a detection probe and detection device. Background Technology

[0002] Sensors, as crucial devices capable of sensing information from a measured object and converting it into an output signal, play an indispensable role in modern detection technology. In operation, by connecting one end of a probe to the sensor and positioning the other end towards the object being measured, the sensor emits a signal that travels through the probe to the surface of the object. The signal is reflected off the surface of the object / the inner wall of its container and re-enters the probe, then returns to the sensor. The sensor then obtains information about the object based on the received signal.

[0003] Traditional probes mainly adopt a single-end transmit-single-receive basic operating mode, that is, the first end transmits the signal, which is reflected by the object under test and received by the second end. This structural design is simple and mature, but it has the problem of not being able to perform multi-dimensional detection of the object under test. Summary of the Invention

[0004] This invention aims to address, to a certain extent, one of the technical problems in related technologies. To this end, this invention provides a detection probe with the advantage of diverse detection dimensions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A detection probe includes a detection unit comprising multiple signal channel layers. Each signal channel layer includes multiple first signal channel bundles arranged around the axis of the detection probe. The multiple signal channel layers are arranged radially along the detection unit. The detection probe also includes a port portion, which includes multiple signal channel branches. Each signal channel branch includes multiple second signal channel bundles. Each signal channel branch is channel-connected to one of the signal channel layers, and different signal channel branches are channel-connected to different signal channel layers. Among the mutually channel-connected signal channel branches and signal channel layers, the first signal channel bundles and the second signal channel bundles are channel-connected.

[0007] The multi-layered signal channel system of the detection unit can form multiple rings around the center of the detection surface. When the signal channel bundles within the same signal channel layer are equidistant from the center of the detection surface, a signal transmission and reception loop equidistant from the center point can be achieved. By configuring multiple port sections connected to different signal channel layers, multiple signal channel branches connected to signal channel bundles at different distances from the center of the detection surface can be obtained. By changing the devices connected to different port sections, i.e., changing the connection method between each signal channel branch and the signal receiver or signal generator, various detection methods can be implemented, adapting to different detection scenarios and effects.

[0008] Optionally, the number of signal channel branches corresponds one-to-one with the number of signal channel layers, and the first signal channel bundle located in the same signal channel layer is connected to the second signal channel bundle in the corresponding signal channel branch.

[0009] The signal channel branches and signal channel layers are in one-to-one correspondence, so that the second signal channel bundle in the signal channel branch can correspond to the first signal channel bundle in the signal channel layer. When the first signal channel bundle and the second signal channel bundle are connected, the detection signal can complete the path from the signal channel branch to the signal channel layer, then be reflected by the test object, and return to the signal channel branch through the signal channel layer, and finally realize the acquisition of the signal and complete the detection.

[0010] Optionally, the detection probe further includes a connecting portion located between the detection portion and the port portion, and connecting the detection portion and the port portion. The first signal channel bundle and the second signal channel bundle, which are interconnected, are connected as one unit within the connecting portion.

[0011] The connecting part is used to classify the first signal channel bundles distributed at different positions of the detector according to their respective signal channel layers, and connect them with the corresponding second signal channel bundles to realize signal transmission, which has the advantage of improving the accuracy of signal detection.

[0012] Optionally, the detection unit further includes a central signal channel core, and the port unit further includes a central branch. The central signal channel core is arranged along the axis of the detection unit, and the innermost signal channel layer surrounds the central signal channel core. The central signal channel core is connected to the central branch channel. The central signal channel core and the central branch cooperate to allow the signal to enter through the port unit and be transmitted along the axis of the detection unit before being emitted from the center of the end face of the detection unit. Alternatively, the signal can enter through the center of the end face of the detection unit and be transmitted to the central branch of the port unit, where the returned detection signal is received by a signal receiver connected to the central branch.

[0013] The signal channel layer includes a first signal channel layer, a second signal channel layer, and a third signal channel layer arranged sequentially in a radial direction away from the central signal channel core. The signal channel branch includes a first port, a second port, and a third port that are separated from each other. The first signal channel layer is connected to the first port channel, the second signal channel layer is connected to the second port channel, and the third signal channel layer is connected to the third port channel.

[0014] In addition to the central signal channel core located at the center of the detection surface, the signal channel layer contains at least three outer signal channel layers. Each signal channel layer is configured to receive reflected signals emitted from any other signal channel layer, enabling the reception of signals from different signal channel layers and adapting to various detection scenarios. Furthermore, the signal channel layers connected to each signal channel branch are different, avoiding mutual interference between signals.

[0015] Optionally, the distance between the first signal channel layer and the central signal channel core is d1, the distance between the second signal channel layer and the first signal channel layer is d2, and the distance between the third signal channel layer and the second signal channel layer is d3. d1, d2, and d3 can form a geometric sequence in sequence.

[0016] The signal channel layers are spaced apart, and the spacing between adjacent signal channel layers forms a geometric sequence. This geometric sequence of signal channel layer spacing creates a reflected signal with a uniformly varying loss rate along the radial direction, facilitating subsequent analysis of the detection signal.

[0017] Optionally, the distance between adjacent signal channel layers is equal, and the distance between the first signal channel layer and the central signal channel core is equal to the distance between adjacent signal channel layers.

[0018] Signal channel layers can be spaced apart, and separators made of different signal channel materials can be filled between the signal channel layers. This increases the distance between the signal channel layer that emits the signal and the signal channel layer that receives the signal, increases the time between signal emission and return, increases the distance from the detection surface required for signal reflection, increases the signal detection depth, and can increase the signal detection dimension.

[0019] Optionally, adjacent signal channel layers are spaced apart, adjacent second signal channel bundles in the signal channel layer are spaced apart, and the spacing between second signal channel bundles in the same signal channel layer is the same.

[0020] Intervals are formed between adjacent signal channel bundles on the same layer. As the distance between the signal channel bundle and the midpoint of the detection surface increases, the number of signal channel bundles that can be installed on one layer increases. Interval setting of signal channel bundles can reduce production costs without affecting the detection dimension.

[0021] Optionally, the number of second signal channel bundles in each signal channel layer is different, and the number of second signal channel bundles in each signal channel layer increases in a radial direction away from the axis of the detection unit.

[0022] Each of the aforementioned signal channel bundles has the same diameter, and the signal channel layer farther from the center of the detection surface has a longer perimeter. The number of signal channel bundles increases radially, which enables the same spacing between each signal channel bundle and results in a more stable signal.

[0023] Optionally, the number of second signal channel bundles in each of the signal channel layers is the same.

[0024] Having an equal number of signal channel bundles in each signal channel layer simplifies the production of detection probes. They can be distributed along a certain radius of the detection surface. By distributing them on the same radius, the variation in the spacing between signal channel bundles or signal channel layers can be limited, which facilitates production.

[0025] Optionally, a gap is formed between adjacent signal channel branches, and the gap between each signal channel branch is filled with stainless steel or a dark core, and the distance between adjacent signal channel branches is the same.

[0026] The signal channel branches are filled with stainless steel or a dark core. By filling them with non-signal channel medium, the distance between the signal channel branches corresponding to different signal channel layers at the port is the same. This allows the signal channel branches with different spacings and the dark core to form an interface shape of the same size, meeting the needs of modular installation and switching matching methods, expanding the scope of application, and improving the configurability of the detection probe.

[0027] Furthermore, the present invention also provides a detection device, which includes a signal transmitter, a signal receiver, and a detection probe as described in any of the preceding claims. The signal channel branch is capable of communicating with either the signal transmitter or the signal receiver channel. The signal transmitter is communicated with at least one of the signal channel branch channels, and the signal receiver is communicated with at least one of the signal channel branch channels. The signal channel branch communicated with the signal transmitter channel is different from the signal channel branch communicated with the signal receiver channel. The reasoning process for the beneficial effects of the detection device provided by the present invention and the aforementioned detection probe is similar and will not be repeated here.

[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain the present invention and should not be construed as limiting the invention.

[0040] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this invention. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0041] The core problem facing current probe technology lies in its limited detection dimension and information acquisition capability. Traditional single-end transmitter-receiver structures can only acquire information from a single node on the surface, making it difficult to achieve differentiated detection at different depths and locations.

[0042] To address the aforementioned problems, this application proposes a detection device, comprising a signal transmitter, a signal receiver, and a detection probe. The signal transmitter transmits a signal to the detection probe, and the signal receiver receives the signal returned from the detection probe, thus completing the detection.

[0043] like Figure 1 and Figure 2 As shown, this application proposes a detection probe, including a detection unit 1. The detection unit 1 includes multiple signal channel layers 11, each signal channel layer 11 including multiple first signal channel bundles 111 arranged around the axis of the detection probe. The multiple signal channel layers 11 are arranged radially along the detection unit 1. The detection probe also includes a port part 2, the port part 2 including multiple signal channel branches 21, each signal channel branch 21 including multiple second signal channel bundles 211. Each signal channel branch 21 is channel-connected to one of the signal channel layers 11, and different signal channel branches 21 are connected to different signal channel layers 11. Among the mutually channel-connected signal channel branches 21 and signal channel layers 11, the first signal channel bundle 111 and the second signal channel bundle 211 are channel-connected.

[0044] In this embodiment, the detection unit 1 is provided with three signal channel layers 11, which are arranged radially along the midpoint of the end face of the detection unit 1. At the same time, the port unit 2 is provided with three signal channel branches 21, which can be connected to a signal transmitter or a signal receiver respectively. By changing the connection method of the three signal channel branches 21, the multi-dimensional detection capability of the signal can be realized.

[0045] The multi-layer signal channel layer 11 of the detection unit 1 can form multiple loops around the axis of the detection unit 1. When the center distance between the first signal channel bundle 111 within the same signal channel layer 11 and the center point of the end face of the detection unit 1 is equal, a signal transceiver loop equidistant from the center point can be achieved. By setting multiple port units 2 connected to different signal channel layers 11 respectively, multiple signal channel branches 21 connected to first signal channel bundles 111 with different center distances from the center point of the end face of the detection unit 1 can be obtained. By changing the devices connected to different port units 2, that is, changing the way each signal channel branch 21 is connected to the signal receiver or signal generator, a variety of different detection methods can be achieved, which can adapt to different detection scenarios and effects.

[0046] Furthermore, the number of signal channel branches 21 corresponds one-to-one with the number of layers of the signal channel layer 11, and the first signal channel bundle 111 located in the same layer of the signal channel layer 11 is connected to the second signal channel bundle 211 in the corresponding signal channel branch 21.

[0047] The signal channel branch 21 and the signal channel layer 11 are in one-to-one correspondence, so that the second signal channel bundle 211 in the signal channel branch 21 can correspond to the first signal channel bundle 111 in the signal channel layer 11. When the first signal channel bundle 111 and the second signal channel bundle 211 are connected, the detection signal can complete the path from the signal channel branch 21 to the signal channel layer 11, then be reflected by the object under test, and return to the signal channel branch 21 through the signal channel layer 11, and finally realize the acquisition of the signal and complete the detection.

[0048] Furthermore, the detection probe also includes a connecting part 3, which is located between the detection part 1 and the port part 2 and connects the detection part 1 and the port part 2. The first signal channel bundle 111 and the second signal channel bundle 211, which are interconnected, are connected as one unit within the connecting part 3.

[0049] The connecting part 3 is used to classify the first signal channel bundles 111 distributed at different positions of the detection part 1 according to the signal channel layer 11 in which they are located, and connect them to the corresponding second signal channel bundles 211 to realize signal transmission, which has the advantage of improving the accuracy of signal detection.

[0050] Furthermore, the detection unit 1 further includes a central signal channel core 12, and the port unit 2 further includes a central branch 22. The central signal channel core 12 is arranged along the axis of the detection unit 1, and the innermost signal channel layer 11 is arranged around the central signal channel core 12. The central signal channel core 12 is in channel communication with the central branch 22. The central signal channel core 12 and the central branch 22 cooperate to allow the signal to enter through the port unit 2 and be transmitted along the axis of the detection unit 1 before being emitted from the center of the end face of the detection unit 1. Alternatively, the signal can enter through the center of the end face of the detection unit 1 and be transmitted to the central branch 22 of the port unit 2, where the returned detection signal is received by a signal receiver connected to the central branch 22.

[0051] The signal channel layer 11 includes a first signal channel layer 112, a second signal channel layer 113, and a third signal channel layer 114 arranged sequentially in a radial direction away from the central signal channel core 12. The signal channel branch 21 includes a first port 212, a second port 213, and a third port 214 that are separated from each other. The first signal channel layer 112 is connected to the first port 212, the second signal channel layer 113 is connected to the second port 213, and the third signal channel layer 114 is connected to the third port 214.

[0052] In other embodiments, the number of signal channel layers 11 can also be other numbers, and multiple signal channel layers 11 can all achieve multidimensional detection.

[0053] In addition to the first signal channel layer 112 located at the center of the end face of the detector 1, the signal channel layer 11 also includes at least two outer signal channel layers 11. Each signal channel layer 11 is configured to receive reflected signals emitted by any other signal channel layer 11, thereby enabling the reception of signals emitted by different signal channel layers 11 and corresponding to different detection scenarios.

[0054] The distance between the first signal channel layer 112 and the central signal channel core 12 is d1, the distance between the second signal channel layer 113 and the first signal channel layer 112 is d2, and the distance between the third signal channel layer 114 and the second signal channel layer 113 is d3. d1, d2, and d3 can form a geometric sequence in sequence.

[0055] Each signal channel layer 11 is spaced apart, and the spacing between adjacent signal channel layers 11 forms a geometric sequence. The geometric sequence spacing of the signal channel layers 11 can generate a reflected signal with a uniformly varying loss rate along the radial direction, which facilitates the analysis of subsequent detection signals.

[0056] In this embodiment, different connection methods are applicable to different scenarios. The specific connection details and corresponding test content are as follows:

[0057] With the signal transmitter connected to the central branch 22 and the signal receivers connected to the first port 212, the second port 213, and the third port 214, the signal is emitted from the central signal channel core 12 and returned from the other three signal channel layers 11, enabling the detection of signals at different distances from the center point.

[0058] With the first port 212 connected to the signal transmitter, and the second port 213, the third port 214, and the central branch 22 connected to the signal receiver, the signal is emitted from the first signal channel layer 112 and returned from the other three signal channel layers 11, which can realize the detection of signals at different distances from the center point and the outer ring.

[0059] With the signal transmitter connected to the second port 213 and the signal receiver connected to the first port 212, the third port 214, and the central branch 22, the signal is emitted from the second signal channel layer 113 and returned from the other three signal channel layers 11, which can realize the detection of signals at different distances between the center point and the inner and outer rings.

[0060] With the signal transmitter connected to the third port 214 and the signal receiver connected to the first port 212, the second port 213, and the central branch 22, the signal is emitted from the third signal channel layer 114 and returned from the other three signal channel layers 11, which can realize the detection of signals at different distances from the center point and the inner circle.

[0061] With the signal transmitter connected to the central branch 22 and the first port 212, and the signal receiver connected to the second port 213 and the third port 214, the signal is emitted from the central signal channel core 12 and the first signal channel layer 112, and returns from the other two signal channel layers 11, which enables the detection of signals at different distances from the large light spot and the outer ring.

[0062] With the signal transmitter connected to the central branch 22 and the second port 213, and the signal receiver connected to the first port 212 and the third port 214, the signal is emitted from the central signal channel core 12 and the second signal channel layer 113, and returns from the other two signal channel layers 11, enabling the detection of inner and outer ring signals at different distances.

[0063] With the signal transmitter connected to the central branch 22 and the third port 214, and the signal receiver connected to the first port 212 and the second port 213, the signal is emitted from the central signal channel core 12 and the third signal channel layer 114 and returned from the other two signal channel layers 11, which can realize the detection signal of the middle area.

[0064] With the signal transmitter connected to the first port 212 and the second port 213, and the signal receiver connected to the central branch 22 and the third port 214, the signal is emitted from the first signal channel layer 112 and the second signal channel layer 113, and returns from the other two signal channel layers 11, which enables the detection of signals in the inner and outer rings.

[0065] With the signal transmitter connected to the first port 212 and the third port 214, and the signal receiver connected to the central branch 22 and the second port 213, the signal is emitted from the first signal channel layer 112 and the third signal channel layer 114 and returns from the other two signal channel layers 11, which enables the detection of the intermediate region and the transmission of the intermediate signal.

[0066] With the signal transmitter connected to the second port 213 and the third port 214, and the signal receiver connected to the central branch 22 and the first port 212, the signal is emitted from the second signal channel layer 113 and the third signal channel layer 114 and returned from the other two signal channel layers 11, which enables the detection of signals in the middle area.

[0067] With the signal transmitter connected to the central branch 22, the first port 212 and the second port 213, and the signal receiver connected to the third port 214, the signal is emitted from the central signal channel core 12, the first signal channel layer 112 and the second signal channel layer 113, and returns from the third signal channel layer 114, which enables the detection of ultra-large light spot signals.

[0068] With the signal transmitter connected to the central branch 22, the first port 212 and the third port 214, and the signal receiver connected to the second port 213, the signal is emitted from the central signal channel core 12, the first signal channel layer 112 and the third signal channel layer 114, and returns from the second signal channel layer 113, which enables the detection of signals in the inner ring of multiple transmitters.

[0069] With the signal transmitter connected to the central branch 22, the second port 213 and the third port 214, and the signal receiver connected to the first port 212, the signal is emitted from the central signal channel core 12, the second signal channel layer 113 and the third signal channel layer 114, and returns from the first signal channel layer 112, which enables the detection of signals in the inner ring of multiple transmitters.

[0070] With the first port 212, the second port 213, and the third port 214 connected to the signal transmitter, and the central branch 22 connected to the signal receiver, the signal is emitted from the first signal channel layer 112, the second signal channel layer 113, and the third signal channel layer 114 and returns from the central signal channel core 12, which enables the detection of signals from the center points of multiple transmitters.

[0071] The above connection method can realize various signal channel arrangement methods of the detection unit 1, and optimize the spatial sampling characteristics according to the detection requirements.

[0072] like Figure 3 As shown, adjacent signal channel layers 11 are tightly fitted together, the second signal channel layer 113 is disposed around the periphery of the first signal channel layer 112, the third signal channel layer 114 is disposed around the periphery of the second signal channel layer 113, and the second signal channel layer 113 separates the first signal channel layer 112 and the third signal channel layer 114.

[0073] In this embodiment, the number of first signal channel bundles 111 of each tightly fitted signal channel layer 11 is fixed, such as... Figure 6As shown, the first signal channel layer 112 has one first signal channel bundle 111, the second signal channel layer 113 has six first signal channel bundles 111, and the third signal channel layer 114 has twelve first signal channel bundles 111. It should be noted that in other embodiments, the two signal channel layers 11 can also be connected to the same signal channel branch 21, in which case the two signal channel layers 11 connected to the same signal channel branch 21 are adjacent.

[0074] The signal channel layers 11 can be tightly fitted together. When the signal channel layers 11 with similar spacing and close to the midpoint of the end face of the detection unit 1 are connected to the signal channel branch 21 connected to the signal transmitter, a large spot-form detection signal can be achieved, which has the advantages of enhancing the detection signal strength and improving the accuracy of the received signal. Moreover, it is simple to manufacture, reducing the difficulty of production.

[0075] like Figure 2 As shown, the distance between adjacent signal channel layers 11 is equal, and the distance between the first signal channel layer 112 and the central signal channel core 12 is equal to the distance between adjacent signal channel layers 11.

[0076] The signal channel layers 11 can be spaced apart, and the space between the signal channel layers 11 can be filled with a separator of non-signal channel material, which increases the distance between the signal channel layer 11 that emits the signal and the signal channel layer 11 that receives the signal, increases the time between signal emission and return, increases the distance away from the detection surface required for signal reflection, increases the signal detection depth, and can increase the signal detection dimension.

[0077] like Figure 4 and Figure 5 As shown, in this embodiment, the first port 212 of the first signal channel layer 112 is connected to the signal transmitter, and the other ports are connected to the signal receiver. At this time, the signal depth received by the second signal channel layer 113 is less than the signal depth received by the third signal channel layer 114.

[0078] Furthermore, adjacent signal channel layers 11 are spaced apart, adjacent second signal channel bundles 211 in the signal channel layer 11 are spaced apart, and the spacing between the second signal channel bundles 211 in the same signal channel layer 11 is the same.

[0079] An interval is formed between adjacent first signal channel bundles 111 on the same layer. As the distance between the first signal channel bundle 111 and the midpoint of the end face of the detector 1 increases, the number of first signal channel bundles 111 that can be installed on one layer increases. The interval arrangement of the first signal channel bundles 111 can reduce production costs without affecting the detection dimension.

[0080] Furthermore, the number of second signal channel bundles 211 in each signal channel layer 11 is different, and the number of second signal channel bundles 211 in each signal channel layer 11 increases in a radial direction away from the axis of the detection unit 1.

[0081] Each of the signal channel bundles has the same diameter, and the signal channel layer 11, which is farther from the center of the detection surface, has a longer perimeter. The number of signal channel bundles increases radially, which enables the same spacing between each signal channel bundle and results in a more stable signal.

[0082] Each of the first signal channel bundles 111 has the same diameter. The signal channel layer 11, which is far from the center of the end face of the detector 1, has a longer perimeter. The number of first signal channel bundles 111 increases radially, which can make the spacing between each first signal channel bundle 111 the same and the obtained signal more stable.

[0083] Furthermore, the number of second signal channel bundles 211 in each of the signal channel layers 11 is the same.

[0084] like Figure 7 and Figure 8 As shown, in this embodiment, the number of first signal channel bundles 111 contained in the signal channel layers 11 other than the first signal channel layer 112 is equal, all being four. This allows for a uniform distribution of the emitted signal, i.e., a uniform distribution of the signal intensity falling on the surface of the object under test, avoiding a situation where the signal intensity received at the center of the end face of the detector 1 is greater than the signal intensity received at the edge of the end face of the detector 1, thus improving the overall performance of the detection system.

[0085] Having an equal number of first signal channel bundles 111 in each signal channel layer 11 simplifies the production of the detection probe. They can be distributed along a radius from the midpoint of the end face of the detection unit 1. By distributing them on the same radius, the variation of the spacing between the first signal channel bundles 111 or the signal channel layers 11 can be limited, which facilitates production.

[0086] Furthermore, a gap is formed between adjacent signal channel branches 21, and the gap between each signal channel branch 21 is used to fill stainless steel or a dark core, and the distance between adjacent signal channel branches 21 is the same.

[0087] The signal channel branches 21 are filled with stainless steel or a dark core. By filling them with a non-signal channel medium, the distance between the signal channel branches 21 corresponding to different signal channel layers 11 in the port section 2 is the same. This allows the signal channel branches 21 with different spacings and the dark core to form an interface shape of the same size, meeting the requirements of modular installation and switching matching methods, expanding the scope of application, and improving the configurability of the detection probe.

[0088] In practical applications, the signal channel branch 21 can be connected to the signal transmitter or the signal receiver channel. The signal transmitter is connected to at least one of the signal channel branch 21 channels, and the signal receiver is connected to at least one of the signal channel branch 21 channels. The signal channel branch 21 connected to the signal transmitter channel is different from the signal channel branch 21 connected to the signal receiver channel.
