Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to vibration testing devices. Background Technology

[0002] In the field of industrial equipment maintenance and fault diagnosis, vibration monitoring is a core method for assessing the health status of equipment. By collecting vibration signals during the operation of industrial equipment using vibration detection devices, and then analyzing the signals, it is possible to determine whether there are any abnormal faults in the equipment.

[0003] Currently, most commonly used vibration testing devices are divided into two categories. One type is installed on the surface of the equipment to be tested by means of bolts, but this type of installation is inconvenient to disassemble and is difficult to switch quickly between different equipment and different testing positions. It is not well adapted to temporary testing and multi-point inspection scenarios. The other type is a handheld vibration testing device. When using it, the user needs to hold the device against the testing surface. Long-term operation can easily cause fatigue, and it is difficult to ensure that the device remains stably attached to the testing surface during the testing process. It is also difficult to adapt to operation in confined spaces. Summary of the Invention

[0004] Therefore, it is necessary to provide a vibration detection device that can meet the application needs of temporary detection and detection in confined spaces, while also ensuring detection accuracy.

[0005] This application provides a vibration detection device, comprising:

[0006] A detection body includes a main body and detection legs connected to the main body. The detection legs are equipped with vibration detectors, which are electrically connected to the main body. The vibration detectors are configured to detect vibration data of the device under test.

[0007] An attachable element is provided at least on the detection leg, and the attachable element is configured to be detachably connected to the detection surface of the device to be tested by an attachment action, so that the detection body can be detachably connected to the detection surface.

[0008] In one embodiment, the attachable member is configured as a magnetic adhesive member, one side of which is adhered to the detection leg and the other side is magnetically connected to the detection surface.

[0009] In one embodiment, the detection leg is further provided with a pressure detector, which is configured to detect the adsorption strength between the magnetic adhesive and the detection surface.

[0010] In one embodiment, the detection leg is configured as a bendable structure, and the bendable structure is configured to adjust the mounting position of the attachable member on the detection surface by bending action.

[0011] In one embodiment, the bendable structure includes a plurality of connecting segments that are sequentially and movably connected, such that the included angle between two adjacent connecting segments is adjustable, and the vibration detector is disposed in at least one of the plurality of connecting segments.

[0012] In one embodiment, the detection leg further includes a flexible covering that covers the outer surface of the bendable structure.

[0013] In one embodiment, the detection feet are multiple, arranged circumferentially along the main body and extending away from the main body. Each detection foot is provided with the vibration detector and the attachable member.

[0014] In one embodiment, both the vibration detector and the attachable member are located at the end of the detection leg furthest from the main body; and / or,

[0015] The attachable member has multiple components, and at least one of the multiple attachable members is disposed on the main body, while the others are disposed on the detection foot; and / or,

[0016] The detection support leg is movably connected to the main body.

[0017] In one embodiment, the detection body further includes a flexible circuit board disposed on the detection leg, and the vibration detector is electrically connected to the body portion via the flexible circuit board; and / or,

[0018] The vibration detector is configured as an acceleration sensor.

[0019] In one embodiment, the main body includes a signal processing unit electrically connected to the vibration detector to receive and process the vibration data; and / or,

[0020] The main body also includes a signal amplification unit electrically connected to the vibration detector to amplify the vibration data; and / or,

[0021] The main body further includes a signal transmission unit electrically connected to the vibration detector, and the signal transmission unit is configured to wirelessly connect to a terminal device to transmit the vibration data to the terminal device; and / or,

[0024] The aforementioned vibration detection device includes a detection body and an attachable component. The detection body includes a main body portion and a detection leg connected to the main body portion. The detection leg is equipped with a vibration detector, which is electrically connected to the main body portion.

The attachable component is provided at least on the detection leg portion and is configured to be detachably connected to the detection surface of the device under test through an attachment action, so that the detection body can be detachably connected to the detection surface. In use, simply align the attachable part with the detection surface of the equipment to be tested. The vibration detection device is then fixed in place by the attachment. The equipment under test drives the entire vibration detection device to vibrate, allowing the vibration detector to accurately collect vibration data. After testing, the vibration detection device can be removed from the detection surface by applying external force. There is no need to disassemble bolts or other fixing structures, nor is it necessary to manually hold it in place for extended periods. It is easy to operate and can be quickly switched between different detection points and different equipment under test, adapting to the needs of temporary testing and multi-point roving testing. At the same time, the attachment of the attachable part ensures that the vibration detection device remains stably attached to the detection surface. Even in confined spaces, it can be fixed by adjusting the position of the detection feet without continuous manual operation. This reduces the workload of operators and avoids interference with the test results caused by shaking or unstable attachment due to manual operation, effectively improving the accuracy of the test.

[0036] See Figure 1 and Figure 2 , Figure 1 A schematic diagram of the vibration detection device according to one embodiment of this application is shown. Figure 2 for Figure 1 A partial enlarged view at point A. An embodiment of this application provides a vibration detection device including a detection body 1 and an attachable member 122. The detection body 1 includes a main body portion 11 and a detection leg 12 connected to the main body portion 11. The detection leg 12 is provided with a vibration detector 121, which is electrically connected to the main body portion 11 and configured to detect vibration data of the device under test. The attachable member 122 is at least provided on the detection leg 12 and is configured to be detachably connected to the detection surface of the device under test via an attachment action, so that the detection body 1 can be detachably connected to the detection surface.

[0037] Specifically, the detection leg 12 can be located on one side of the main body 11 and extend along a predetermined direction. The detection leg 12 can be fixed to the detection surface of the device under test by the attachable member 122. A vibration detector 121 is provided on the detection leg 12. In use, simply align the attachable member 122 with the detection surface of the device under test, and the vibration detection device can be fixed by the attachment. The device under test drives the entire vibration detection device to vibrate, allowing the vibration detector 121 to accurately collect the vibration data of the device under test. After the test is completed, only external force needs to be applied to remove the vibration detection device from the detection surface. It does not require disassembly and assembly of bolts or other fixing structures, nor does it require prolonged manual holding to maintain contact. It is easy to operate and can quickly switch between different testing points and different devices to be tested, adapting to the needs of temporary testing and multi-point roving testing. At the same time, thanks to the attachment of the attachable part 122, the vibration testing device can always be stably attached to the testing surface. Even in a confined space, it can be fixed and installed by adjusting the position of the testing support 12 without continuous manual operation. This reduces the workload of operators and avoids interference with the test results caused by shaking and unstable contact due to manual operation, effectively improving the accuracy of the test.

[0038] In this design, only the detection leg 12 can be fixed to the detection surface, meaning the attachment 122 is only provided on the detection leg 12, while the main body 11 is suspended. This fixing method allows the detection leg 12 to be inserted into a narrow space to complete the adsorption, fixation, and detection even if there are other obstructing structures around the detection surface, improving spatial adaptability and making it suitable for more complex and confined detection scenarios. To ensure the stability of the vibration detection device, the size and / or weight of the detection leg 12 and the connection area between the detection leg 12 and the detection surface can be appropriately increased. This ensures the stability of the vibration detection device on the detection surface and prevents the gravity of the main body 11 from affecting the adhesion stability between the detection leg 12 and the detection surface, thus ensuring the accuracy of vibration data acquisition. If the detection space is sufficient, the attachment 122 can also be provided on both the main body 11 and the detection leg 12, meaning that both the main body 11 and the detection leg 12 of the detection body 1 are simultaneously attached to the detection surface, further improving the overall stability of the fixation, reducing signal loss during vibration transmission, and further improving detection accuracy.

[0039] The attachable component 122 can be attached to the detection surface of the device under test through adsorption. For example, the attachable component 122 is configured as a magnetic adhesive component, with one side of the magnetic adhesive component bonded to the detection leg 12 and the other side magnetically connected to the detection surface. This magnetic adhesive component allows the detection leg 12 to be detachably installed on the detection surface through one-side bonding and the other-side magnetic attraction. In actual use, when it is necessary to switch or remove the detection body 1, the detection leg 12 can simply be pulled off the detection surface without additional tools, allowing for quick installation and removal. It requires minimal operating space, and this magnetic adsorption method provides a stable adsorption force, ensuring that the detection leg 12 remains in contact with the detection surface during the testing process, thus guaranteeing the accuracy of the test. Furthermore, for industrial equipment made of ferromagnetic materials such as steel, direct magnetic fixation can be achieved without additional processing of the fixing structure on the detection surface, preventing damage to the structure of the device under test and adapting to the temporary testing needs of most industrial equipment. In other embodiments, the attachable element 122 can also be configured as a magnetic element or an electromagnet, thereby directly magnetically adsorbing onto the surface of the metal device to be tested. This allows for convenient and quick installation and fixation, with good adsorption strength. In this case, the magnetic element or electromagnet can be directly fixed or snap-fitted to the testing foot 12. For example, if the testing foot 12 has a mounting groove, the electromagnet or magnetic element can be snap-fitted into the mounting groove. The magnetic element or electromagnet can also be connected to the testing foot 12 by magnetic adsorption, facilitating the replacement of attachable elements 122 with different adsorption strengths to adapt to the needs of testing bodies 1 of different weights.

[0040] In other embodiments, the attachable part 122 can also be configured as an adhesive, such as double-sided tape or double-sided nano-adhesive. In this case, in order to ensure the bonding strength, the adhesive can be replaced in time when switching the detection position to ensure that sufficient bonding strength is obtained each time it is fixed, and to avoid the vibration detection device falling off during the detection process due to adhesive failure. At the same time, the adhesive has a low cost, good stability after fixing, and can also adapt to the use requirements of non-ferromagnetic material detection surfaces, further expanding the applicable scenarios of the vibration detection device.

[0041] In other embodiments, the attachable member 122 can also be configured as a vacuum suction cup, which is fixed to the detection surface by vacuum negative pressure adsorption, adapting to the use of non-ferromagnetic materials for the device under test, further expanding the applicability of the device. That is, in this application, the specific attachment method of the attachable member 122 on the detection surface is not specifically limited, as long as a detachable connection can be achieved through the attachment effect, ensuring the stability of the fit to the detection surface. The detachable connection here means that the connection form of the detection body 1 can be manually disassembled without the aid of tools.

[0042] To promptly detect the adsorption strength of the magnetic adhesive on the detection surface, in some embodiments of this application, a pressure detector is also provided on the detection foot 12. The pressure detector is configured to detect the adsorption strength between the magnetic adhesive and the detection surface. Specifically, the pressure detector is positioned close to the magnetic adhesive and can detect the adsorption pressure of the magnetic adhesive on the detection surface in real time. Operators can use the pressure data from the detector to determine whether the connection between the magnetic adhesive and the detection surface is stable. If the adsorption pressure is lower than a preset threshold, the position can be adjusted and reinstalled promptly to avoid unstable adhesion due to insufficient adsorption force, which would affect the accuracy of vibration detection data. Therefore, to facilitate timely monitoring of changes in adhesion pressure, a display module can be set to display the adsorption pressure value in real time, or the pressure detector signal can be connected to a terminal device 2 such as a mobile phone or computer, allowing operators to view the adsorption status in real time and monitor connection stability during the detection process. This facilitates timely detection and adjustment of abnormalities, reduces the probability of invalid detection, and improves detection efficiency. Alternatively, an alarm module can be directly set on the detection body 1. When the adhesion pressure is lower than the threshold, the alarm module is triggered to remind the operator to adjust in time, eliminating the need for continuous monitoring of the data and making it more convenient to use. The alarm module can be configured as a speaker alarm or an indicator light alarm.

[0043] In other embodiments, the vibration detection device can also detect the adhesion strength of the attachable part 122 in other ways, such as by judging the vibration signal collected by the vibration detector 121. If the collected vibration signal has obvious abnormal fluctuations and the amplitude exceeds the preset normal range, it is determined that the attachable part 122 is not stable in contact with the detection surface. At this time, the alarm module is triggered to remind the operator to reinstall and fix it.

[0044] The vibration detector 121 is configured as an accelerometer. This accelerometer can directly acquire acceleration signals during vibration, thereby outputting stable vibration data. It has high detection accuracy, is compact, and can adapt to the small-size installation requirements of the detection leg 12, reducing the overall size of the detection leg 12 and facilitating its insertion into confined spaces for detection and installation. Of course, in other embodiments, the vibration detector 121 can also be configured as other detectors, such as velocity sensors or displacement sensors. This application does not make specific limitations, and those skilled in the art can select the corresponding type of vibration detector 121 according to actual detection needs and detection scenarios to adapt to different detection accuracy and detection range requirements.

[0045] In some embodiments of this application, the detection leg 12 is configured as a bendable structure, and the bendable structure is configured to adjust the installation position of the attachable member 122 on the detection surface through a bending action. Specifically, by setting the detection leg 12 as a bendable structure, when entering a confined detection space, the angle of the detection leg 12 can be pre-bent and adjusted according to the shape of the detection space and the position of the point to be detected, so that the attachable member 122 can be accurately aligned and fitted to the detection surface. This avoids the inability to align the detection point due to the angle and position limitations of the main body 11, further improving the adaptability of confined spaces and complex structural equipment. It can reach detection positions that conventional straight detection legs 12 cannot reach, further expanding the applicable scenarios of the detection device. Moreover, since the detection leg 12 adopts a bendable structure, the detection position of the detection leg 12 can also be changed through a bending action without changing the position of the main body 11, realizing rapid detection of multiple points at the same detection position. This reduces the operational burden caused by repeatedly adjusting the position of the main body 11 and improves the efficiency of multi-point detection. Specifically, the detection leg 12 can be configured as a flexible and shape-fixed metal leg that can maintain its current shape after bending without the need for additional fixing structures, making it more convenient to operate. Alternatively, multiple hinge nodes can be set in the connecting section 123, and the bending angle of the detection leg 12 can be adjusted through the hinge nodes. Once the bending is in place, the angle can be locked to complete the adjustment.

[0046] For example, refer to Figure 1 and Figure 2 The bendable structure includes multiple connecting segments 123, which are sequentially and movably connected, allowing the included angle between adjacent connecting segments 123 to be adjustable. A vibration detector 121 is located on at least one of the connecting segments 123. Specifically, the multiple connecting segments 123 can be sequentially and movably connected, allowing the included angle between adjacent connecting segments 123 to be adjustable. This changes the posture of the detection leg 12 and adjusts the position of the attachable member 122, enabling the attachable member 122 to better adapt to detection surfaces of different shapes and positions, ensuring a tight and stable fit. Furthermore, a damping structure or locking structure can be provided between adjacent connecting segments 123, locking the current included angle after adjustment to prevent angle deviation during detection, which could affect the accuracy of the detection position and ensure the precision of vibration data acquisition.

[0047] Multiple connecting segments 123 can be sequentially hinged together end to end. For example, adjacent connecting segments 123 can be connected by a hinge shaft and the angle after bending can be fixed by a damping structure. Alternatively, they can be configured as shape-adjustable metal bending rods, capable of being bent and adjusted at any angle while maintaining their shape. They can also be configured as electrically adjustable angle structures, automatically adjusting the bending angle through a drive component to adapt to different usage requirements. This application does not impose specific limitations on these configurations. The number of connecting segments 123 can be two, three, four, or more. Those skilled in the art can flexibly select the number of connecting segments 123 according to the structural complexity of the device to be tested and the size of the testing space, ensuring that the testing leg 12 can be smoothly adjusted to the required bending angle.

[0048] Furthermore, by placing the vibration detector 121 on the corresponding connecting segment 123, it can collect vibration data close to the detection surface, reducing losses during vibration transmission and further improving detection accuracy. The vibration detector 121 can be placed on one of multiple connecting segments 123, or it can be placed on multiple connecting segments 123, thereby simultaneously collecting vibration data from multiple points. This enables synchronous detection of multiple points within the same detection area, further improving the efficiency of multi-point detection and reducing the need for multiple fixed detection steps. The number of attachable parts 122 can be set one-to-one with the number of vibration detectors 121, meaning that each vibration detector 121 is located at an attachable part 122. This ensures that each vibration detector 121 is in close contact with the detection surface, reducing the problem of loose contact between other vibration detectors 121 caused by fixing a single attachable part 122, and ensuring the accuracy of vibration data collection from multiple points.

[0049] For example, the vibration detector 121 and the attachable member 122 are both located at the end of the detection leg 12 away from the main body 11. That is, the vibration detector 121 and the attachable member 122 are both located on the connecting section 123 furthest from the main body 11. In other words, the structure for collecting vibration data is located at the end of the detection leg 12. This not only makes it convenient for the detection leg 12 to extend into a narrow space, allowing the vibration detector 121 to be close to the position to be detected, but also avoids vibration interference from the main body 11 and other structures, further improving the accuracy of vibration data acquisition.

[0050] Refer again Figure 1 and Figure 2In some embodiments of this application, the detection leg 12 further includes a flexible covering 124, which covers the outer surface of the bendable structure. Specifically, the flexible covering 124 can protect the internal bendable structure and wiring. Simultaneously, the flexible covering 124 is soft and will not affect the bending action of the detection leg 12. It also prevents the bendable metal structure from scratching the detection surface and avoids vibration signal interference caused by direct rigid contact between the bendable structure and the detection surface, further improving the accuracy of vibration data acquisition. Furthermore, multiple small suction cup structures can be provided on the side of the flexible covering 124 facing the detection surface, further improving the fit between the detection leg 12 and the detection surface, enhancing stability. The suction effect of the multiple small suction cups can also disperse the suction pressure, achieving stable fit even on rough detection surfaces, further improving the device's adaptability to different detection surfaces.

[0051] To further improve detection accuracy and the fixation strength of the detection subject 1, in one embodiment, referring to Figure 1 and Figure 3 The detection legs 12 are multiple, arranged circumferentially along the main body 11 and extending away from the main body 11. Each detection leg 12 is equipped with a vibration detector 121 and an attachment member 122. Specifically, the multiple detection legs 12 are simultaneously fixed to the detection surface, which can distribute the overall weight of the detection body 1 and prevent excessive force on a single detection leg 12, thus avoiding unstable adhesion. At the same time, the multiple detection legs 12 can support the main body 11 from different positions, further improving the stability of the entire detection body 1 and reducing the impact of body shaking on the detection results. In addition, each of the multiple detection legs 12 is equipped with a vibration detector 121, which can simultaneously collect vibration data from different points, realizing multi-point synchronous detection. This reduces the number of disassembly and assembly operations, improves detection efficiency, and allows for cross-validation of multiple sets of data, further improving the accuracy of vibration detection results and providing more comprehensive data support for judging the operating status of the equipment under test.

[0052] In one embodiment, reference is made to Figure 1 The device employs eight detection legs 12, forming an octopus-like structure with a main body 11 and eight peripheral detection legs 12. This allows for stable attachment to different positions on the detection surface. Even on uneven surfaces, the angle and position of each detection leg 12 can be adjusted to ensure a stable fit, further enhancing the device's adaptability to complex detection surfaces. Simultaneously, multiple distributed detection points cover a wider detection range, collecting richer vibration data and facilitating the analysis and determination of the fault location and severity within the tested equipment. Of course, in other embodiments, the number of detection legs 12 can be greater than or less than eight.

[0053] Furthermore, there are multiple attachable members 122, with at least one of them located on the main body 11 and the rest on the detection legs 12. When the detection space is sufficiently open, the attachable members 122 on both the main body 11 and the detection legs 12 can be used to fix the entire detection body 1 to the detection surface. Compared to fixing it only by the detection legs 12, the overall contact area of ​​fixing it to the detection surface is larger, the connection stability is stronger, and the probability of the device shaking during the detection process can be effectively reduced, unnecessary vibration interference can be reduced, and the accuracy of vibration data acquisition can be further improved. When the detection space is narrow, the attachmentable members 122 on the detection legs 12 can be used to complete the fixation, suspending the main body 11 to avoid obstruction structures, which is suitable for the use needs of narrow detection scenarios. This flexible arrangement allows the vibration detection device to adjust the fixing method according to the actual detection scenario, taking into account the adaptability of complex and narrow scenarios and the fixing stability in open scenarios, further improving the environmental adaptability of the device.

[0054] To further improve the flexibility of the vibration detection device, in one embodiment, the detection legs 12 are movably connected to the main body 11. Specifically, the detection legs 12 and the main body 11 can be connected by a hinge or a ball joint, allowing adjustment of the initial angle between the detection legs 12 and the main body 11. When facing detection surfaces with different inclination angles and shapes, the initial angle of each detection leg 12 can be pre-adjusted, making it easier for the detection legs 12 to align with the detection points, further enhancing the device's adaptability to different detection scenarios. During transportation and storage, the detection legs 12 can also be folded down, reducing the overall space occupied by the device and making it easier to store, transport, and use. When some detection legs 12 are not in use, they can also be folded down to avoid collisions or interference with other structures of the equipment under test, further improving usability. Of course, in other embodiments, the detection legs 12 can also be fixedly connected to the main body 11.

[0055] Reference Figure 1 and Figure 2In some embodiments of this application, the detection body 1 further includes a flexible circuit board disposed on the detection leg 12, and the vibration detector 121 is electrically connected to the body 11 through the flexible circuit board. Specifically, the flexible circuit board can bend synchronously with the bending action of the detection leg 12, preventing internal circuit breakage due to repeated bending of the detection leg 12, thus improving the service life of the bendable structure and the stability of the circuit connection. Simultaneously, the flexible circuit board is thin and lightweight, not significantly increasing the overall weight of the detection leg 12, nor affecting the bending and shaping effect of the detection leg 12, and can adapt to the small-size design requirements of the detection leg 12. Furthermore, the flexible circuit board has neat wiring and can be directly attached to the inner wall of the detection leg 12 without occupying extra space, facilitating the detection leg 12 to maintain a smaller external size and making it easier to extend into confined spaces to complete operations. In other embodiments, the flexible circuit board can also be configured as a flexible cable structure, with a flexible protective layer covering the internal wires, which can also bend synchronously with the detection leg 12, meeting the wiring requirements of the bendable structure.

[0056] Reference Figure 1 and Figure 3 In some embodiments of this application, the main body 11 includes a signal processing unit 111, which is electrically connected to the vibration detector 121 to receive and process vibration data. This converts the vibration signal into easily readable and stored vibration data, facilitating subsequent processing and analysis to determine if the operating status of the device under test is abnormal. Simultaneously, the signal processing unit 111 can also incorporate a pre-set anomaly detection algorithm to directly perform preliminary analysis on the collected vibration data, identify abnormal vibration signals, and synchronously send the anomaly results to the terminal device 2. This allows operators to quickly locate abnormal points and improves the efficiency of fault detection.

[0057] Furthermore, the main body 11 also includes a signal transmission unit 113, which is electrically connected to the vibration detector 121 and configured to wirelessly connect to the terminal device 2 to transmit vibration data to the terminal device 2. Specifically, the signal transmission unit 113 can be signal-connected to both the signal processing unit 111 and the terminal device 2, thereby transmitting the processed vibration data to the terminal device 2 in real time. This allows operators to directly view vibration data curves and anomaly analysis results on the terminal device 2 without requiring operators to read the data from the main body 1 at close range. This enables remote data acquisition and monitoring, adapting to the remote operation requirements of high-risk detection scenarios. It also facilitates the unified management of data from all detection points on the same terminal when multiple detection devices are operating simultaneously. This facilitates subsequent comparative analysis of long-term vibration data from the same equipment, timely detection of subtle changes in equipment status, and earlier discovery of potential operational faults. This improves the management efficiency of multi-area synchronous detection. Of course, in other embodiments, the signal transmission unit 113 can also be connected to the terminal device 2 via wired transmission, which provides stronger connection stability, better anti-interference capability, and adaptability to data transmission requirements in complex electromagnetic environments. Those skilled in the art can select a suitable transmission method according to the actual usage scenario.

[0058] For further details, please refer to the following: Figure 1 and Figure 3 The main body 11 also includes a signal amplification unit 112, which is electrically connected to the vibration detector 121 to amplify vibration data. Specifically, the signal amplification unit 112 can be electrically connected to both the signal processing unit 111 and the vibration detector 121, thereby amplifying the vibration data. This prevents the vibration signal from being too weak to be accurately identified and collected, improves the accuracy of detecting low-amplitude, minute vibrations, and facilitates the signal processing unit 111 to promptly capture early, subtle abnormal vibrations during equipment operation, further enhancing the ability to identify faults early. Simultaneously, the amplified vibration signal has stronger anti-interference capabilities, preventing environmental noise from covering the effective signal during transmission and ensuring the accuracy of subsequent data processing and analysis.

[0059] In some embodiments of this application, the main body 11 further includes a power supply module 114, which is electrically connected to the vibration detector 121 to supply power to the vibration detector 121. Specifically, the power supply module 114 can be configured as a built-in rechargeable battery, which can power the entire detection body 1 without an external power cord. This avoids the obstruction caused by an external power cord to the adjustment of the detection position and operation in confined spaces, further improving the flexibility of the device and making it more suitable for outdoor detection operations without an external power supply. A single full charge can support long-term continuous detection, meeting the battery life requirements of daily equipment detection. In other embodiments, the power supply module 114 can also be configured as an external power interface, which can provide continuous power through an external power source when long-term continuous detection is required, avoiding power outages and adapting to the needs of long-term online monitoring.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
