Technical Field

[0001] This invention relates to the field of steel rolling automation, and in particular to a method, device and related equipment for judging the working status of a looper trolley. Background Technology

[0002] Currently, most existing technologies use laser sensors to detect the working status of the looper trolley. However, laser sensors have high requirements for the operating environment. If the operating environment is harsh, the laser sensor is prone to detection errors, resulting in low detection accuracy of the looper trolley's working status. Summary of the Invention

[0003] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] Existing technologies for detecting the working status of a looper trolley typically use laser sensors to detect the tilt of the trolley on both sides, meaning they only detect the tilt along one axis and cannot detect tilt along other axes, resulting in low accuracy in detecting the working status of the looper trolley. Therefore, this application proposes a new technical solution to address the above problems.

[0005] In a first aspect, the present invention provides a method for judging the working state of a looper trolley, comprising: acquiring working state information of a preset position of the looper trolley, the working state information including three-axis tilt information and three-axis vibration frequency information, wherein the looper trolley includes: a wire rope, a guide wheel and a chain; determining a first comparison result between the three-axis tilt information and a first tilt threshold; determining a second comparison result between the three-axis vibration frequency information and a second vibration frequency threshold; and judging abnormal parts of the looper trolley based on the first comparison result and the second comparison result.

[0006] In one feasible implementation, the above method further includes: if the first comparison result is less than a first preset threshold, determining that the wire rope, guide wheel and chain of the looper trolley are in normal working condition.

[0007] In one feasible implementation, the above method further includes: determining that the abnormal part of the looper trolley is a wire rope when the first comparison result is greater than or equal to a first preset threshold and the second comparison result is less than or equal to a second preset threshold.

[0008] In one feasible implementation, the working status information further includes triaxial vibration amplitude information, and the above method further includes: when the first comparison result is greater than or equal to a first preset threshold and the second comparison result is greater than a second preset threshold; generating a vibration amplitude image at a preset position based on the triaxial vibration amplitude information, wherein the vibration amplitude image includes a correspondence image between the position information of the looper trolley and the vibration amplitude; and determining abnormal parts of the looper trolley based on the vibration amplitude image.

[0009] In one feasible implementation, when the vibration amplitude is positively correlated with the position information, the abnormal part of the looper trolley is determined to be the guide wheel.

[0010] In one feasible implementation, if the vibration amplitude image is distorted, the abnormal part of the looper trolley is determined to be the chain.

[0011] In one feasible implementation, the method described in any of the preceding methods further includes: obtaining service life information of the looper trolley; and compensating for a first tilt threshold and / or a second vibration frequency threshold based on the service life information.

[0012] Secondly, the present invention proposes a device for judging the working state of a looper trolley, comprising: an acquisition unit for acquiring working state information of a preset position of the looper trolley, the working state information including three-axis tilt information and three-axis vibration frequency information, wherein the looper trolley includes: a wire rope, a guide wheel, and a chain; a first determination unit for determining a first comparison result between the three-axis tilt information and a first tilt threshold; a second determination unit for determining a second comparison result between the three-axis vibration frequency information and a second vibration frequency threshold; and a judgment unit for judging abnormal parts of the looper trolley based on the first comparison result and the second comparison result.

[0013] Thirdly, the present invention proposes an electronic device, including a processor and a memory, wherein the memory stores computer program instructions, which are executed by the processor to perform the method for determining the working state of the looper trolley as described in any of the first aspects.

[0014] Fourthly, the present invention proposes a storage medium on which program instructions are stored, which, when run, are used to execute the method for determining the working state of the looper trolley according to any one of the first aspects.

[0015] In summary, the method for determining the working state of a looper trolley according to embodiments of this application includes: acquiring working state information of a preset position of the looper trolley, the working state information including three-axis tilt information and three-axis vibration frequency information, wherein the looper trolley includes: a wire rope, a guide wheel, and a chain; determining a first comparison result between the three-axis tilt information and a first tilt threshold; determining a second comparison result between the three-axis vibration frequency information and a second vibration frequency threshold; and determining abnormal parts of the looper trolley based on the first and second comparison results. This method can accurately detect the working state of the looper trolley without using a laser sensor, eliminating the environmental limitations of using a laser sensor for detecting the working state of the looper trolley; it can simultaneously detect the tilt and vibration frequency of the three axes of a preset position of the looper trolley, and accurately locate abnormal parts of the looper trolley based on the first comparison result between the three-axis tilt information and the first tilt threshold and the second comparison result between the three-axis vibration frequency information and the second vibration frequency threshold, thereby improving the detection accuracy and efficiency of the looper trolley's working state.

[0029] Loop 10; Loop trolley 20. Detailed Implementation

[0030] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus. The technical solutions of the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0031] Figure 1 This is a schematic diagram illustrating a usage scenario of a looper trolley, as provided in an embodiment of this application. Figure 1 As shown, in actual production, due to the high position of the looper 10, if the looper trolley 20 malfunctions in its working state, it will cause problems such as long repair time and high difficulty. In order to solve the above problems, firstly, the present invention provides a method for judging the working state of the looper trolley. Figure 2 This is a flowchart illustrating a method 100 for determining the working state of a looper trolley, as provided in an embodiment of this application. Figure 2As shown, method 100 may include the following steps:

[0032] Step S110: Obtain the working status information of the looper trolley at the preset position. The working status information includes three-axis tilt information and three-axis vibration frequency information. The looper trolley includes: wire rope, guide wheel and chain.

[0033] For example, Figure 3 This is a schematic diagram illustrating the three-axis deflection of a looper trolley when it tilts, as provided in an embodiment of this application. Figure 3 As shown, the three axes can be represented by the X-axis, Y-axis, and Z-axis, respectively. The X-axis is the side where the looper trolley drive device is installed; the Y-axis is the side extending from the guide wheel steel structure at the looper trolley's inlet side to the guide wheel steel structure at the looper trolley's outlet side; and the Z-axis is the side relative to the plane perpendicular to the X-axis and Y-axis. Specifically, when the looper trolley tilts along the X-axis, it rotates relative to the Y-axis; when it tilts along the Y-axis, it rotates relative to the X-axis; and when it tilts simultaneously along both the X-axis and Y-axis, it rotates relative to the Z-axis.

[0034] For example, the aforementioned three-axis tilt information can be obtained through a tilt detection device, such as an electronic inclinometer or a mechanical inclinometer. This tilt detection device can simultaneously acquire tilt information along three axes and transmit the detected three-axis tilt information. For example, Figure 4 This is a schematic diagram showing the installation locations of a tilt detection device and a vibration detection device provided in an embodiment of this application. Figure 4 As shown, the aforementioned preset positions can be at the four corners of the looper trolley. Specifically, tilt detection devices can be installed at each of the four corners of the looper trolley to detect the three-axis tilt information of the looper trolley.

[0035] It should be noted that this installation method places the tilt detection device close to the edge of the looper carriage. Understandably, if the three-axis tilt information of the looper carriage becomes abnormal, the tilt deviation at the edge of the looper carriage will be larger. Therefore, this installation method is beneficial for magnifying the detection of three-axis tilt anomalies of the looper carriage and improving the detection accuracy of the looper carriage's tilt.

[0036] For example, the aforementioned triaxial vibration frequency information can be obtained through a vibration detection device, such as a vibration detector or vibration testing machine. This vibration detection device can simultaneously acquire vibration frequency information along three axes and transmit the detected triaxial vibration frequency information. For example, as... Figure 4As shown, the aforementioned preset position can be relatively close to the guide wheel. Specifically, vibration detection devices can be installed at the guide wheel steel structure on the inlet side and the guide wheel steel structure on the outlet side of the looper trolley to detect the triaxial vibration frequency information of the looper trolley. It should be noted that, due to this installation method, the vibration detection device is installed close to the guide wheel of the looper trolley. It can be understood that once the triaxial vibration frequency information of the looper trolley is abnormal, since the installation position of the vibration detection device is close to the vibration source, i.e., the guide wheel, this installation method is beneficial for amplifying the detection of triaxial vibration frequency anomalies of the looper trolley, and thus improving the detection accuracy of the looper trolley's vibration frequency.

[0037] Step S120: Determine the first comparison result between the triaxial tilt information and the first tilt threshold.

[0038] For example, the aforementioned first tilt threshold can be calculated based on historical tilt data during the use of the looper trolley. For instance, the first tilt threshold can be determined by calculating a linear regression equation for the tilt using the least squares method based on the historical tilt data; or by collecting tilt data from abnormal states of the looper trolley using historical tilt data, and then taking the average value as the first tilt threshold. The aforementioned first comparison result can be the absolute value of the difference between the aforementioned three-axis tilt information and the first tilt threshold. Specifically, taking a looper trolley in a cold-rolled galvanizing production line as an example, the aforementioned first tilt threshold can be 3°.

[0039] Step S130: Determine the second comparison result between the triaxial vibration frequency information and the second vibration frequency threshold.

[0040] For example, the aforementioned second vibration frequency threshold can be calculated based on vibration frequency data from the historical use of the looper trolley. For instance, it can be calculated based on historical vibration frequency data from the looper trolley's usage. Alternatively, based on the historical vibration frequency data, a linear regression equation for the vibration frequency can be calculated using the least squares method to determine the second vibration frequency threshold; or, by collecting vibration frequency data from abnormal states of the looper trolley using historical vibration frequency data, the average value can be taken as the second vibration frequency threshold. The aforementioned second comparison result can be the absolute value of the difference between the aforementioned three-axis vibration frequency information and the second vibration frequency threshold. Specifically, taking a looper trolley in a cold-rolled galvanizing production line as an example, the aforementioned second vibration frequency threshold can be 1.5 mm / s.

[0041] It should be noted that the aforementioned vibration detection device can also be used to detect the temperature of the part where the vibration detection device is installed. It should be noted that due to the vibration of the looper carriage, friction occurs between the looper carriage and other components, leading to an increase in the temperature of the looper carriage. Therefore, the vibration frequency can be determined based on temperature. For example, if the vibration detection device detects that the temperature of its installation location is higher than the ambient temperature, it can be determined that the vibration frequency of the looper carriage is too high. In this case, the subsequent determination in step S130 is performed. For example, if the vibration detection device detects that the temperature of its installation location is higher than 30°C, it can be determined that the vibration frequency of the looper carriage is too high. In this case, step S130 is executed to determine the vibration frequency of the looper carriage.

[0042] Step S140: Based on the first comparison result and the second comparison result, determine the abnormal part of the looper trolley.

[0043] It should be noted that if the first comparison result is greater than 0, that is, if the absolute value of the difference between the three-axis tilt information and the first tilt threshold is greater than 0, then the following parts of the looper trolley are determined to be abnormal: guide wheel, chain, and wire rope. Whether the abnormal part of the looper trolley is specifically an abnormal guide wheel, chain, or wire rope requires further determination based on subsequent steps of this method.

[0044] Therefore, the method for judging the working state of the looper trolley proposed in this application obtains the working state information of the looper trolley at a preset position. The working state information includes three-axis tilt information and three-axis vibration frequency information. The looper trolley includes a wire rope, a guide wheel, and a chain. The method determines a first comparison result between the three-axis tilt information and a first tilt threshold; determines a second comparison result between the three-axis vibration frequency information and a second vibration frequency threshold; and judges the abnormal parts of the looper trolley based on the first comparison result and the second comparison result. The above method achieves the following technical effects: it can accurately detect the working status of the looper trolley without using a laser sensor, thus eliminating the environmental limitations of using a laser sensor to detect the working status of the looper trolley; it can simultaneously detect the tilt and vibration frequency of three axes of a preset part of the looper trolley, and based on the first comparison result of the three-axis tilt information with a first tilt threshold and the second comparison result of the three-axis vibration frequency information with a second vibration frequency threshold, it can locate abnormal parts of the looper trolley, thereby improving the detection accuracy and efficiency of the looper trolley's working status. By detecting the tilt and vibration frequency of the looper trolley in real time, the operating status of the looper trolley can be accurately controlled, which is beneficial for timely detection of abnormalities in the operation of the looper trolley and ensuring stable production.

[0045] In some examples, the above method further includes: if the first comparison result is less than a first preset threshold, determining that the wire rope, guide wheel and chain of the looper trolley are in normal working condition.

[0046] For example, the first preset threshold can be 0. When the first preset threshold is 0, if the wire rope of the looper trolley breaks, the guide wheel is damaged, or the chain is damaged, the tilt angle of at least one of the three axes of the looper trolley is greater than or equal to the first preset threshold. Conversely, if the first comparison result is less than the first preset threshold, that is, if the tilt angles of all three axes of the looper trolley are less than the first preset threshold, it can be determined that the tilt angles of all three axes of the looper trolley are within the normal working range of the looper trolley, that is, the wire rope, guide wheel, and chain of the looper trolley are in normal working condition. If the looper trolley still cannot work normally under such circumstances, other parts of the looper trolley need to be inspected and checked.

[0047] For example, if the inclination of all three axes is less than 3°, it can be determined that the wire rope, guide wheel and chain of the looper trolley are in normal working condition.

[0048] Therefore, the method for judging the working status of the looper trolley proposed in this application can accurately identify abnormal parts of the looper trolley by comparing the first comparison result with the first preset threshold, that is, by comparing the absolute value of the difference between the three-axis tilt of the looper trolley and the first tilt threshold with the first threshold. When the tilt of the three axes of the looper trolley is less than the first tilt threshold, it is determined that the abnormal parts of the looper trolley are not the wire rope, guide wheel, or chain, which helps to improve the efficiency of subsequent inspection of abnormal parts of the looper trolley.

[0049] In some examples, the above method further includes: determining that the abnormal part of the looper trolley is a wire rope when the first comparison result is greater than or equal to a first preset threshold and the second comparison result is less than or equal to a second preset threshold.

[0050] For example, both the first preset threshold and the second preset threshold can be set to 0. Therefore, if the first comparison result is greater than or equal to the first preset threshold, that is, if the inclination of at least one of the three axes of the looper is greater than or equal to the first inclination threshold, the abnormal part of the looper needs to be determined based on the second comparison result to be the guide wheel, chain, or wire rope. It should be noted that if only the wire rope of the looper breaks, it will not cause an abnormality in the vibration frequency of the looper. Therefore, if the second comparison result is less than or equal to the second preset threshold, that is, if the vibration frequency of all three axes of the looper is less than the second vibration frequency threshold, the abnormal part of the looper can be determined to be the wire rope.

[0051] For example, if the inclination of any one of the three axes is greater than or equal to 3° and the vibration frequency of all three axes is less than or equal to 1.5 mm / s, it can be determined that the wire rope of the looper trolley has broken.

[0052] Therefore, the method for judging the working status of the looper trolley proposed in this application can accurately judge the abnormal parts of the looper trolley based on the first comparison result and the second comparison result. That is, it can accurately judge whether the abnormal part of the trolley is the wire rope based on the three-axis tilt and the three-axis vibration frequency, thereby saving the judgment time of the abnormal parts of the looper trolley. At the same time, it is conducive to saving the maintenance time of the wire rope of the looper trolley, thereby promoting the rapid recovery of subsequent production.

[0053] In some examples, the working status information also includes triaxial vibration amplitude information. The method further includes: when the first comparison result is greater than or equal to a first preset threshold and the second comparison result is greater than a second preset threshold; generating a vibration amplitude image at a preset position based on the triaxial vibration amplitude information, wherein the vibration amplitude image includes a correspondence image between the position information of the looper trolley and the vibration amplitude; and determining abnormal parts of the looper trolley based on the vibration amplitude image.

[0054] For example, when the first and second preset thresholds are both zero, and the first comparison result is greater than or equal to the first preset threshold, and the second comparison result is greater than the second preset threshold (i.e., the tilt of at least one of the three axes is greater than or equal to the first tilt threshold, and the vibration frequency of at least one of the three axes is greater than the second vibration frequency threshold), the abnormal part of the looper trolley is the guide wheel or chain. Specifically, the current position information of the looper trolley can be used as the independent variable, and the vibration amplitude as the dependent variable to generate a corresponding image of the looper trolley's position information and vibration amplitude. Based on the vibration amplitude image, the abnormal part of the looper trolley can be further judged. Specifically, the abnormal part of the looper trolley can be judged based on the inflection point of the vibration amplitude image and / or the changing trend of the vibration image.

[0055] Specifically, if the tilt angle of at least one of the three axes of the looper is greater than or equal to 3°, and the vibration frequency of at least one of the three axes is greater than 1.5 mm / s, the abnormal part of the looper, specifically the guide wheel or the chain, can be determined based on the inflection point of the corresponding image of the position information of the looper and the vibration amplitude and / or the changing trend of the vibration image.

[0056] In one feasible embodiment, the aforementioned vibration amplitude image can be displayed on an HMI (human-machine interface) for easy analysis and viewing by staff.

[0057] Therefore, the method for judging the working status of the looper trolley proposed in this application can accurately judge the abnormal parts of the looper trolley, specifically the guide wheel or chain, based on the correspondence image between the position information of the looper trolley and the vibration amplitude, when the first comparison result is greater than or equal to the first preset threshold and the second comparison result is greater than the second preset threshold. This makes the process of judging the abnormal parts of the looper trolley more intuitive and scientific.

[0058] In some examples, when the vibration amplitude is positively correlated with the position information, the abnormal part of the looper trolley is identified as the guide wheel.

[0059] It should be noted that when the abnormal part of the looper carriage is the guide wheel, that is, when the guide wheel of the looper carriage is damaged, the vibration amplitude of the looper carriage gradually increases with the change of the position of the looper carriage. That is, the trend of the change of the vibration amplitude image of the looper carriage is a steady increase. Therefore, if the abnormal part of the looper carriage has been determined to be the guide wheel or the chain based on the aforementioned method, it can be determined that the abnormal part of the looper carriage is the guide wheel.

[0060] For example, Figure 5 A schematic wave diagram of a vibration amplitude image provided in an embodiment of this application; Figure 6 This is a schematic wave diagram illustrating yet another vibration amplitude image provided in an embodiment of this application. For example... Figure 5 As shown, when the vibration amplitude of the looper trolley changes periodically with the position information of the looper trolley as shown in waveform S1, it can be determined from the vibration image of the looper trolley that the guide wheel and chain of the looper trolley are in normal working condition. Figure 6 As shown, when the slope of the vibration amplitude image of the looper trolley suddenly increases when the looper trolley moves to position a, that is, when the vibration amplitude of the looper trolley changes with the position information of the looper trolley as shown in waveform S2, specifically, after the looper trolley moves to position a, the vibration amplitude is positively correlated with the position information. That is, when the slope of the vibration amplitude image increases sharply and becomes a fixed value after the looper trolley moves to position a, the abnormal part of the looper trolley can be determined to be the chain based on the vibration image of the looper trolley.

[0061] Understandably, before performing the step of determining the abnormal part of the looper trolley based on the vibration amplitude image, the vibration amplitude image of the looper trolley under normal working conditions can be determined based on the historical operating data of the looper trolley. That is, the periodic change image of the vibration amplitude of the looper trolley with the position information of the looper trolley can be determined. The above periodic change image is used as the vibration amplitude reference image of the looper trolley. Then, the vibration amplitude image of the looper trolley acquired in real time is compared with the above vibration amplitude reference image to determine the operating status of the guide wheel and chain of the looper trolley.

[0062] It should be noted that the above vibration amplitude images can be updated in real time based on the historical operating data of the looper trolley.

[0063] Therefore, the above method, based on vibration amplitude images, can determine that the abnormal part of the looper trolley is the guide wheel when the vibration amplitude and position information are positively correlated. This enables automated judgment of the operating status of the looper trolley guide wheel, avoiding misjudgments and errors caused by manual judgment. It also simplifies the process of troubleshooting abnormalities in the looper trolley guide wheel, improves the efficiency of determining abnormalities, helps avoid major accidents such as looper trolley overturning, and improves production safety.

[0064] In some examples, when the vibration amplitude image is distorted, the abnormal part of the looper trolley is identified as the chain.

[0065] It should be noted that once the chain of the looper trolley breaks, the vibration amplitude of the looper trolley will suddenly increase sharply, that is, the trend of the vibration image of the looper trolley will show obvious irregular changes. Therefore, if the abnormal part of the looper trolley has been determined to be the guide wheel or the chain based on the aforementioned method, and if the vibration amplitude image shows distortion at a certain position, then the abnormal part of the looper trolley can be determined to be the chain.

[0066] For example, Figure 7 This application provides another schematic wave diagram of vibration amplitude image. For example... Figure 7 As shown, if the vibration image of the looper trolley exhibits a jittery distortion at point b, as shown in S3, that is, the slope increases sharply at point b and changes continuously with the change of position information, then the abnormal part of the looper trolley is determined to be the chain.

[0067] Therefore, the above method can quickly and accurately identify the abnormal part of the looper trolley as the chain when the vibration amplitude image shows the above-mentioned jittery distortion. This saves the time for troubleshooting abnormalities in the looper trolley chain, which is conducive to the staff to quickly repair the chain later, and thus facilitates the rapid resumption of production.

[0068] In some examples, such as the method described in any of the preceding methods, the method further includes: obtaining service life information of the looper trolley; and compensating for a first tilt threshold and / or a second vibration frequency threshold based on the service life information.

[0069] For example, the service life of the looper can be calculated based on its manufacturing date, purchase date, usage frequency, and number of uses. Then, based on this service life information, compensation is applied to the first tilt angle threshold and the second vibration frequency threshold. It should be noted that after years of use, the looper may deform or wear. In this case, compensating for the first tilt angle threshold and / or the second vibration frequency threshold based on the service life information helps to further improve the accuracy of this method and avoids safety hazards caused by low detection accuracy of abnormal working conditions of the looper due to aging.

[0070] In some feasible examples, the above method further includes: recording historical abnormal data of the looper trolley; establishing an abnormal part judgment model of the looper trolley based on the historical abnormal data; wherein the historical abnormal part data includes historical abnormal tilt information data of the looper trolley, historical abnormal vibration frequency data, and abnormal part judgment results; comparing the tilt information and vibration frequency information of the looper trolley obtained in real time with the historical abnormal data of the looper trolley; if the comparison results are consistent, automatically outputting the abnormal part comparison result of the looper trolley; and displaying the abnormal part of the trolley on the monitoring screen based on the above abnormal comparison result, while issuing an early warning to remind staff to check and repair the looper trolley in a timely manner, so as to shorten the maintenance cycle of the looper trolley and improve the detection efficiency of abnormal working parts of the looper trolley.

[0071] In one feasible implementation, the trolley can be equipped with an electrical control system to implement any of the methods described above. Figure 8 This is a structural schematic diagram of an electrical control system provided in an embodiment of this application. Figure 8 As shown, the aforementioned electrical control system includes: a data acquisition module, a control module, and a display module. The data acquisition module includes a tilt detection device and a vibration detection device. The control module includes a PLC controller (Programmable Logic Controller). The PLC controller can be a Siemens 1200 PLC controller, used to receive, transmit, and process the three-axis tilt information acquired by the tilt detection device and the three-axis vibration frequency information acquired by the vibration detection device. The three-axis tilt information and three-axis vibration frequency information can be transmitted to the main system via a communication module, such as a Siemens 400 PLC system. The display module is used to display the monitoring screen; specifically, after determining that the working state of the looper trolley has become abnormal, it can also be used to display information such as:

[0072] The alarm message "Lock trolley malfunction, please check" is displayed to remind staff to check the lock trolley promptly. It should be noted that the data collected by the above data acquisition module can be recorded using a PDA (data acquisition device) and displayed on a display module for staff analysis and review.

[0073] Secondly, the present invention proposes a device for judging the working status of a looper trolley. Figure 9 This is a structural schematic diagram of a device 200 for determining the working status of a looper trolley, provided in an embodiment of this application. Figure 9 As shown, the device 200 may include: an acquisition unit 210, a first determination unit 220, a second determination unit 230, and a judgment unit 240.

[0074] The acquisition unit 210 is used to acquire the working status information of the looper trolley at a preset position. The working status information includes three-axis tilt information and three-axis vibration frequency information. The looper trolley includes a wire rope, a guide wheel, and a chain.

[0075] The first determining unit 220 is used to determine the first comparison result between the triaxial tilt information and the first tilt threshold.

[0076] The second determining unit 230 is used to determine the second comparison result between the triaxial vibration frequency information and the second vibration frequency threshold.

[0077] Judgment unit 240. Used to determine abnormal parts of the looper trolley based on the first comparison result and the second comparison result.

[0078] Thirdly, the present invention proposes an electronic device. Figure 10 This is a structural schematic diagram of an electronic device 300 provided in an embodiment of this application. For example...
