Description

Technical Field

[0001] This invention relates to the field of transmission system technology, and in particular to a transmission system detection method, apparatus, medium, program product, and transmission system. Background Technology

[0002] In the field of conveyor system inspection, obtaining the rotational state of the driven roller is crucial information for determining whether the conveyor belt is slipping. Existing technologies typically use proximity switches to monitor the rotational state of the driven roller. Specifically, existing conveyor belt inspection systems usually install proximity switches on the frame near the end face of the driven roller. A pulse signal is generated by detecting whether a protruding stop on the end face enters the sensor's monitoring area. When the driven roller rotates, the stop on its end face periodically enters the proximity switch's monitoring area. Each entry triggers the proximity switch to generate a pulse-like arrival signal, while the arrival signal disappears when it leaves the monitoring area. The rotational state of the driven roller is inferred by counting the number of pulses per unit time or checking the continuity of the arrival signal.

[0003] However, because the conveying system is susceptible to vibration, load changes or equipment aging during operation, the driven roller may be axially displaced, causing the stop to always deviate from the monitoring area. The proximity switch will not be able to detect any positioning signal, which may lead to a misjudgment that the driven roller is in a stopped rotating state, affecting production continuity and safety.

[0025] In the field of conveyor system inspection, obtaining the rotational state of the driven roller is crucial information for determining whether the conveyor belt is slipping. Existing technologies typically use proximity switches to monitor the rotational state of the driven roller. Specifically, existing conveyor belt inspection systems usually install proximity switches on the frame near the end face of the driven roller. A pulse signal is generated by detecting whether a protruding stop on the end face enters the sensor's monitoring area. When the driven roller rotates, the stop on its end face periodically enters the proximity switch's monitoring area. Each entry triggers the proximity switch to generate a pulse-like arrival signal, while the arrival signal disappears when it leaves the monitoring area. The rotational state of the driven roller is inferred by counting the number of pulses per unit time or checking the continuity of the arrival signal.

[0026] However, because the conveying system is susceptible to vibration, load changes or equipment aging during operation, the driven roller may be axially displaced, causing the stop to always deviate from the monitoring area. The proximity switch will not be able to detect any positioning signal, which may lead to a misjudgment that the driven roller is in a stopped rotating state, affecting production continuity and safety.

[0027] Please see Figure 1 This invention provides a method for detecting a conveying system, applied to a conveying system including a drive roller, a driven roller, and a conveyor belt. The conveyor belt is drivenly connected to the drive roller and the driven roller. The driven roller includes a roller body and a marking structure. The roller body has an end face along the axial direction of the driven roller, and the marking structure protrudes from the end face. The method for detecting the conveying system includes steps S100-S200: S100. Obtain the distance data between the measurement position point and the driven roller, wherein the measurement position point is set at intervals along the axial direction of the driven roller and the end face.

[0028] For example, the measurement position point refers to a reference point for non-contact ranging. This measurement position point is fixed in space and ensures a clear measurement path between it and the driven roller. For example, the measurement position point can be equipped with a distance detection device, such as an infrared rangefinder, whose ranging path can be approximately perpendicular to the end face. With the driven roller rotating normally, the end face and the marking structure will periodically alternate entering the ranging path, causing periodic fluctuations in the distance data acquired by the distance detection device.

[0029] Understandably, the information contained in distance data differs from the signal generated by a proximity switch. Specifically, a proximity switch can only provide discrete binary signals, indicating whether a stop has entered the monitoring area ("present" or "absent"), with limited information content, failing to reflect the specific distance changes between the detected object and the sensor. Distance data, on the other hand, contains continuous analog signals, recording the positional changes of the end face and marker structure along the ranging path. This not only allows determination of whether the marker structure has passed through the ranging path but also the perception of its distance and its changing trend.

[0030] S200: Determine the rotation state of the driven roller based on distance data.

[0031] For example, the rotation status can be determined by analyzing the fluctuation characteristics of the distance data. Specifically, when the driven roller rotates normally, the distance data will exhibit a clear periodic variation pattern. This periodic variation reflects the regular movement trajectory of the marking structure relative to the measurement position point. Therefore, by analyzing whether the periodic characteristics of the distance data are complete, continuous, and stable, it is possible to effectively determine whether the driven roller is in a normal rotation state. For example, when the rotation state of the driven roller is abnormal, the periodic characteristics of the distance data will be disrupted, manifesting as missing, disordered, or abnormal amplitude of the periodic signal. For instance, when the driven roller slips or jams, the distance data will not show complete periodic fluctuations, or the amplitude of the fluctuations will be significantly reduced; when the driven roller stops completely, the distance data will appear as a basically unfluctuated straight line or a stable value with only slight noise.

[0032] It should be explained that the determination of the driven roller's rotation state is based on the relative change in distance data. Even if the driven roller undergoes axial displacement, causing a change in the reference distance between the measurement position point and the end face, as long as the marking structure can still periodically enter the distance measurement path, the periodic fluctuation characteristics of the distance data can be effectively captured. This gives the driven roller's rotation state a large tolerance, avoids the situation where the marking structure deviates from the detection area due to the driven roller's axial displacement, and solves the problem of not being able to reliably determine the driven roller's rotation state due to the driven roller's axial displacement.

[0033] like Figure 2 As shown, in some embodiments, the distance data includes multiple distance values; step S200 includes S210-220: S210, Determine the range of multiple distance measurements.

[0034] For example, the distance measurement value refers to the instantaneous distance value between the measurement location point and the end face or marking structure surface collected at a single sampling moment. These distance measurement values ​​constitute a continuous data sequence reflecting the relative position change during the rotation of the driven roller.

[0035] For example, in this embodiment, the multiple distance measurement values ​​used to determine whether the rotation state of the driven roller is in a first abnormal state can be distance data points continuously collected within a first set time window. For example, within a 100-millisecond time window, 100 distance measurement values ​​are continuously collected at a sampling interval of 1 millisecond. For example, the duration of the first set time window should be greater than or equal to one rotation cycle of the drive roller to ensure that the distance change characteristics of the driven roller within at least one complete rotation cycle can be fully captured, thereby improving the accuracy of state judgment. Preferably, the duration of the first set time window is greater than multiple rotation cycles of the drive roller, for example, covering 3-5 rotation cycles. By comparing and analyzing the range data of multiple rotation cycles, the interference of random fluctuations can be effectively eliminated, improving the reliability and stability of rotation state judgment. It should be noted that the specific setting of the first set time window can be adjusted according to the real-time rotation cycle of the drive roller in the actual application scenario. In high-speed rotation scenarios, a shorter first set time window can be used, while in low-speed heavy-load scenarios, the first set time window should be extended accordingly to ensure that sufficient periodic feature information can be obtained under any working condition. The real-time rotation cycle of the drive roller can be obtained by an encoder installed on the drive roller.

[0036] For example, the range refers to the difference between the maximum and minimum values ​​in a set of distance measurements. The range reflects the variation in the height of the protruding part of the marking structure relative to the end face reference within a specific time period. For instance, during a normal rotation of one revolution of the driven roller, the range should be approximately equal to the height of the marking structure protruding from the end face; however, when the rotation is abnormal, the range will be significantly reduced because the marking structure fails to pass completely through the detection area.

[0037] S220. If the range is less than the first threshold, the rotation state of the driven roller is determined to be the first abnormal state; wherein, the first threshold is determined based on the flatness of the end face.

[0038] For example, the first threshold is determined based on the fluctuation range of the distance data from the end face. In practical applications, due to the microscopic unevenness of the end face itself and / or the vibration of the driven roller, the collected distance data will have slight fluctuations. The first threshold is set according to the maximum possible fluctuation range of the distance data from the end face.

[0039] For example, the first abnormal state is the stop state, which means that the driven roller has completely stopped rotating. When the driven roller is in the stop state, the marking structure remains stationary relative to the measurement position point, and the distance data no longer shows periodic changes, but fluctuates within a relatively stable range. This fluctuation is caused only by the microscopic unevenness of the end face and / or the vibration of the driven roller, and its fluctuation amplitude is much smaller than the range when rotating normally.

[0040] Understandably, if the range remains below the first threshold, it indicates that the fluctuation range of the distance data has narrowed to the typical characteristic range of the stopped state, and the driven roller can be confirmed to be in a stopped state.

[0041] like Figure 3 As shown, in some embodiments, the first threshold is determined based on the flatness of the end face, and the determination of the first threshold includes the following steps S221-S222: S221. Obtain distance reference data between a reference position point and multiple position points on the end face, wherein the reference position points are spaced apart from the end face along the axial direction of the driven roller.

[0042] For example, the reference position point can be the aforementioned measurement position point, thereby ensuring that the benchmark for flatness measurement is consistent with the benchmark for subsequent actual inspection, improving the accuracy of the first threshold setting. In actual operation, the reference position point remains fixed, and different areas of the end face are sequentially passed through the distance measurement path of the reference position point by the rotation of the driven roller.

[0043] For example, the distance reference data includes multiple distance reference values, which are instantaneous distance values ​​collected at different locations on the end face as it traverses the distance measurement path. By collecting distance data from multiple sampling points around the end face, a complete dataset reflecting the overall flatness of the end face can be constructed. The higher the sampling density, the more accurate the characterization of the end face flatness.

[0044] S222. Determine the flatness of the end face based on distance reference data.

[0045] For example, by analyzing the acquired distance reference dataset, the difference between the maximum and minimum values ​​in the distance reference data can be calculated. This difference is the apparent unevenness range of the end face on the measurement path, and this difference can be set as the first threshold.

[0046] Understandably, since the first threshold is used to determine whether the driven roller is in a stopped state, and in the stopped state, the fluctuation of the distance data is entirely caused by the unevenness of the end face, setting the first threshold to the unevenness range of the end face itself can ensure accurate differentiation between the periodic distance changes during normal rotation and the minute fluctuations during stoppage. Understandably, even if the measurement reference distance changes due to axial displacement of the driven roller, as long as the unevenness characteristics of the end face remain unchanged, the effectiveness of the first threshold will not be affected. This ensures the stability and reliability of detecting the rotational state of the driven roller under different installation positions.

[0047] like Figure 4 As shown, in some embodiments, the distance data includes multiple distance values; step S200 includes S230-240: S230, Determine the range of multiple distance measurements.

[0048] For example, in this embodiment, the multiple distance measurement values ​​used to determine whether the rotation state of the driven roller is a second abnormal state can be distance data points continuously collected within a second set time window. For example, within a 100-millisecond time window, 100 distance measurement values ​​are continuously collected at a sampling interval of 1 millisecond.

[0049] For example, the duration of the second set time window can be one rotation cycle of the drive roller to ensure that the distance change characteristics of the driven roller within a complete rotation cycle can be fully captured, thereby improving the accuracy of state judgment. It should be noted that the specific setting of the second set time window can be adjusted according to the real-time rotation cycle of the drive roller in the actual application scenario. A shorter second set time window can be used in high-speed rotation scenarios, while a correspondingly longer second set time window can be used in low-speed, heavy-load scenarios to ensure that sufficient periodic feature information can be obtained under any operating condition. The real-time rotation cycle of the drive roller can be obtained through an encoder installed on the drive roller.

[0050] S240. If the range is less than the second threshold, the rotation state of the driven roller is determined to be the second abnormal state; wherein, the second threshold is determined based on the distance by which the marking structure protrudes from the end face along the axial direction of the driven roller.

[0051] For example, the second threshold is set based on the protrusion height of the marking structure. For example, the second threshold is obtained by measuring the protrusion distance of the marking structure from the end face and multiplying that distance by an adjustment factor less than 1, such as 0.5-0.8. It should be explained that the adjustment factor needs to be set based on the accuracy requirements of the transmission system. For example, in applications with lower accuracy requirements, the adjustment factor can be set to a smaller value, such as 0.6 or 0.7; while in applications with higher accuracy requirements, the adjustment factor should be set to a larger value, such as 0.8 or 0.9, or even 1.

[0052] For example, the second abnormal state includes axial displacement of the driven roller and rotational jamming of the driven roller. It should be noted that when the driven roller experiences axial displacement, the marking structure will still pass completely through the ranging path during rotation, but because the driven roller is offset relative to the measurement position point, the reference level of the ranging value changes, which may cause the range to be less than the normal value. Conversely, when the driven roller jams during rotation, the marking structure may fail to pass completely through the ranging path in the current rotation cycle, resulting in the actual range being less than the normal value. Both of these situations will cause the range to be less than the second threshold set based on the complete protrusion height, thus being identified as the second abnormal state.

[0053] Understandably, if the range within any rotation cycle of the drive roller is less than the second threshold, it indicates that the marking structure has failed to fully exhibit its expected height characteristics within that detection cycle. In other words, the conveying system has deviated from its normal operating state, requiring timely warning and intervention. This real-time judgment mechanism based on a single rotation cycle can quickly capture instantaneous anomalies, providing timely fault warnings to the system and effectively preventing further deterioration of the abnormal state.

[0054] like Figure 5 As shown, in some embodiments, the second threshold is determined based on the distance by which the marking structure protrudes from the end face along the axial direction of the driven roller. The determination of the second threshold includes the following steps S241-S243: S241. Obtain the first measurement information between the reference position point and the end face. The reference position point is set at intervals along the axial direction of the driven roller and the end face.

[0055] For example, the first measurement information refers to the distance value collected when the end face passes through the distance measurement path from the reference position point during the rotation of the driven roller. For example, the driven roller can be slowly rotated one revolution, and distance data can be continuously collected. The maximum value is recorded as the first measurement information, which reflects the farthest distance between the end face and the reference position point on the distance measurement path. To ensure measurement accuracy, data can be collected repeatedly over multiple rotation cycles, and the consistently occurring maximum value is taken as the final first measurement information.

[0056] S242. Obtain the second measurement information between the reference location point and the marker structure.

[0057] For example, the second measurement information includes the distance value collected when the marking structure passes through the ranging path from the reference position point during the rotation of the driven roller. For example, distance data can be continuously collected by controlling the driven roller to rotate slowly one revolution, and the minimum value is recorded as the second measurement information, reflecting the shortest distance between the marking structure and the reference position point on the ranging path. To ensure measurement accuracy, data can be collected repeatedly over multiple rotation cycles, and the consistently occurring minimum value is taken as the final second measurement information.

[0058] S243. Determine the distance by which the marking structure protrudes from the end face along the axial direction of the driven roller based on the first measurement information and the second measurement information.

[0059] For example, subtracting the first measurement information from the second measurement information yields the difference, which represents the axial protrusion distance of the marker structure over the end face. It can be understood that the first measurement information corresponds to the farthest distance between the end face and the reference position point along the ranging path, while the second measurement information corresponds to the shortest distance between the marker structure and the reference position point along the ranging path. The difference between the two accurately reflects the actual axial protrusion of the marker structure. For example, based on the protrusion distance and an adjustment coefficient, a second threshold can be obtained, where the adjustment coefficient is set based on the accuracy requirements of the transmission system.

[0060] like Figure 6 As shown, in some embodiments, the transmission system detection method further includes steps S300-S400: S300. If the rotation state of the driven roller is determined to be the first abnormal state, then the first alarm message is issued.

[0061] For example, the first alarm information includes an audible and visual alarm signal and / or a first status indication message. When the driven roller is detected to be in a first abnormal state, the warning light of the control conveyor system flashes and the buzzer sounds continuously, and / or, a warning message of "driven roller stop abnormal" is sent to the designated terminal equipment to prompt maintenance personnel to immediately handle the situation on-site to prevent conveyor belt blockage or equipment damage.

[0062] S400. If it is determined that the rotation state of the driven roller is a second abnormal state, a second alarm message is issued.

[0063] For example, the second alarm information includes a warning signal and / or a second status indication. When the driven roller is detected to be in a second abnormal state, the warning light of the control conveyor system flashes and emits an intermittent warning sound, and / or sends a "driven roller malfunction" warning message to the designated terminal equipment, prompting maintenance personnel to carry out maintenance during the planned downtime, thereby achieving predictive maintenance and preventing the abnormal state from deteriorating further.

[0064] Understandably, the first alarm message targets immediate shutdown faults, requiring a prompt response; the second alarm message targets gradual anomalies, providing decision support for preventative maintenance. The combination of the first and second alarm messages ensures both the safety of the transmission system and improves maintenance efficiency.

[0065] In some embodiments, the conveying system detection method may further include a self-diagnostic method for detecting the operating status of the distance detection device installed at the measurement location point. It is understood that in actual operating environments, there may be situations where the distance detection device itself malfunctions, leading to abnormal output data. For example, contamination of the infrared rangefinder probe, optical path obstruction, or circuit malfunctions can cause data to remain constant, fluctuate significantly, or exceed the measurement range. Such data anomalies directly interfere with the accurate judgment of the driven roller's rotation state, potentially triggering false alarms or missed alarms. Therefore, the self-diagnostic method of this embodiment can periodically or in real-time analyze the characteristics of the distance detection device's output data, thereby eliminating interference caused by the distance detection device's own malfunctions in judging the driven roller's rotation state.

[0066] For example, the self-diagnostic method includes: determining the maximum and minimum achievable distance values ​​between the measurement point and the end face based on the actual installation location of the distance detection device; determining whether the distance data output by the distance detection device experiences a continuous interruption with no output, or an out-of-limit situation where the distance data continuously exceeds the maximum distance value or continuously falls below the minimum distance value; if the distance data experiences an interruption or out-of-limit situation, then the distance detection device is marked as faulty. Optionally, if the distance data experiences an interruption or out-of-limit situation, a fault alarm is triggered to alert the operator that the distance detection device is faulty.

[0067] It is understandable that if the distance detection device itself malfunctions, the abnormal data it outputs will directly lead to inaccurate judgment of the rotation status of the driven roller. This embodiment uses pre-set physical extreme values ​​based on the actual installation position, namely the maximum and minimum distance values, as objective benchmarks for data validity. It monitors the two typical fault modes of the distance data output by the distance detection device: interruption and exceeding limits. This can proactively and promptly identify the abnormality of the distance sensor, ensuring that the distance data used to judge the rotation status of the driven roller is true and valid, and avoiding false alarms, missed alarms, or misoperations in the conveyor system caused by problems with the distance detection device itself.

[0068] like Figure 7 As shown, based on the same inventive concept, this application also provides a conveying system detection device 500, applied to a conveying system. The conveying system includes a drive roller, a driven roller, and a conveyor belt. The conveyor belt is drivenly connected to the drive roller and the driven roller. The driven roller includes a roller body and a marking structure. The roller body has an end face along the axial direction of the driven roller, and the marking structure protrudes from the end face.
