[0042] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0044] In the embodiments of this application, the terms "first" and "second" are used to distinguish identical or similar items with essentially the same function and effect, without limiting their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that the terms "first" and "second" do not necessarily imply that they are different.

[0045] It should be noted that, in the embodiments of this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0046] As mentioned earlier, speed measuring rollers are widely used to monitor the running speed of materials in real time to ensure the stability of the production process, the uniformity of product quality, and the safety of equipment operation. For example, in the continuous strip rolling process, speed measuring rollers need to accurately measure the linear speed of the strip to adjust the roll gap pressure and rolling rhythm of the mill; in the paper industry, speed measuring rollers are used to monitor the running speed of paper to match the parameters of coating, drying and other process links; in the textile industry, speed measuring rollers are used to control the tension of yarn and the weaving speed.

[0047] Traditional speed measurement technology often suffers from measurement deviations under high-speed and high-load conditions due to factors such as slippage, wear, and vibration between the material and the speed measuring roller. This leads to decreased measurement accuracy, insufficient equipment stability, and consequently affects production efficiency and product qualification rate.

[0048] In view of this, embodiments of this application provide a speed measurement method and related apparatus. By combining a dual-speed-measuring roller redundancy design with a dynamic data fusion algorithm, a speed measurement system with high precision, high stability and intelligent monitoring capabilities is constructed, effectively improving the accuracy and stability of speed measurement.

[0049] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0050] Figure 1 This is a schematic diagram of a scenario provided for an embodiment of this application, such as... Figure 1 As shown, it includes a conveyor belt 1, a first speed measuring unit 2, and a second speed measuring unit 3.

[0051] The first speed measuring unit 2 includes a first speed measuring roller 21, a first encoder 22, and a first adjustment module 23; the second speed measuring unit 3 includes a second speed measuring roller 31, a second encoder 32, and a second adjustment module 33.

[0052] Conveyor belt 1, also known as material belt, is used to transport materials during the production process.

[0053] The first speed measuring roller 21, also known as the lower speed measuring roller, is in contact with the lower surface of the conveyor belt 1 and rolls by friction with the conveyor belt 1 to measure the running speed of the conveyor belt 1.

[0054] The first encoder 22 is used to detect the rolling speed of the first speed measuring roller 21 in order to measure the running speed of the conveyor belt 1.

[0055] The first adjustment module 23 is used to adjust the pressure between the first speed measuring roller 21 and the conveyor belt 1 so that the pressure between the first speed measuring roller 21 and the conveyor belt 1 is within a preset pressure range.

[0056] The second speed measuring roller 31, also known as the upper speed measuring roller, is in contact with the upper surface of the conveyor belt 1 and rolls by friction with the conveyor belt 1 to measure the running speed of the conveyor belt 1.

[0057] The second encoder 32 is used to detect the rolling speed of the second speed measuring roller 31 in order to measure the running speed of the conveyor belt 1.

[0058] The second adjustment module 33 is used to adjust the pressure between the second speed measuring roller 31 and the conveyor belt 1 so that the pressure between the second speed measuring roller 31 and the conveyor belt 1 is within a preset pressure range.

[0059] In some embodiments, such as Figure 1As shown, the first speed measuring roller 21 and the second speed measuring roller 31 are arranged opposite to each other on the upper and lower surfaces of the conveyor belt 1, and are used to simultaneously measure the speed at the same position of the conveyor belt 1, thereby improving the accuracy of the measured running speed of the conveyor belt 1.

[0060] Figure 2 This is a flowchart illustrating a speed measurement method provided in an embodiment of this application, as shown below. Figure 2 As shown, it includes:

[0061] S201. Obtain the first running speed of the conveyor belt measured by the first speed measuring roller, and the second running speed of the conveyor belt measured by the second speed measuring roller.

[0062] The execution subject of this application embodiment can be a conveyor belt control system.

[0063] In some embodiments, the control system may acquire a first running speed of the conveyor belt measured by a first speed measuring roller via a first encoder, and acquire a second running speed of the conveyor belt measured by a second speed measuring roller via a second encoder.

[0064] For example, the first encoder can collect the rotational speed data (such as the rotation angle) of the first speed measuring roller and convert the collected rotational speed data into an electrical signal and send it to the control system. The control system can obtain the first running data of the conveyor belt based on the received rotational speed data and the circumference of the first speed measuring roller.

[0065] It should be understood that the method for obtaining the second running data is similar to the method for obtaining the first running data, and will not be repeated here.

[0066] S202. Determine the target operating speed of the conveyor belt based on the first operating speed and the second operating speed.

[0067] In some embodiments, when the first operating speed and the second operating speed are obtained, it can be determined whether the first operating speed and the second operating speed are abnormal.

[0068] For example, if the first operating speed or the second operating speed is outside the preset speed range, that is, if the first operating speed or the second operating speed is higher than the preset speed upper limit or lower than the preset speed lower limit, then it can be determined that the first operating speed or the second operating speed is abnormal.

[0069] For example, if the first or second operating speed changes abruptly or fluctuates drastically, it can be determined that there is an anomaly in the first or second operating speed.

[0070] In some embodiments, when both the first operating speed and the second operating speed are within the normal range, the target operating speed of the conveyor belt can be determined in the following manner:

[0071] In one possible implementation, the first operating speed or the second operating speed can be used as the target operating speed.

[0072] In one possible implementation, the average of the first and second running speeds can be used as the target running speed.

[0073] In one possible implementation, the first running speed can be filtered to obtain a third running speed, which can then be used as the target running speed; or, the second running speed can be filtered to obtain a fourth running speed, which can then be used as the target running speed.

[0074] In one possible implementation, the first and second running speeds can be filtered separately to obtain the third and fourth running speeds; the average of the third and fourth running speeds can be used as the target running speed.

[0075] Among them, filtering the first operating speed and / or the second operating speed can be performed by Kalman filtering to improve the accuracy of obtaining the first operating speed and / or the second operating speed and reduce the measurement error caused by measurement noise.

[0076] Optionally, to further improve measurement accuracy, infrared speed sensors and laser displacement sensors can be installed to form a multi-sensor redundant data acquisition system. Speed ​​data of the conveyor belt is simultaneously acquired by the encoder, infrared sensor, and laser displacement sensor, forming a multi-dimensional data source. A weighted Kalman filter algorithm is then used to process the speed data of the conveyor belt acquired by each sensor to obtain the target operating speed of the conveyor belt.

[0077] In some embodiments, if the first operating speed or the second operating speed is abnormal, the target operating speed can be determined in the following manner:

[0078] Taking the first abnormal running speed as an example:

[0079] In one possible implementation, the second running speed can be used as the target running speed.

[0080] In one possible implementation, the second running speed can be filtered, and the filtered speed can be used as the target running speed.

[0081] It should be understood that in the event of an abnormal second operating speed, the method for determining the target operating speed based on the first operating speed is similar to that described above, and will not be repeated here.

[0082] In some embodiments, if both the first operating speed and the second operating speed are abnormal, the control system may output a measurement abnormality alarm message so that the relevant user can handle the abnormality of the first speed measuring roller and the second speed measuring roller.

[0083] The speed measurement method provided in this application acquires a first running speed of the conveyor belt measured by a first speed measuring roller and a second running speed of the conveyor belt measured by a second speed measuring roller; based on the first and second running speeds, a target running speed of the conveyor belt is determined. The above method employs a redundant dual-speed measuring roller design for parallel data acquisition, ensuring that even if one speed measuring roller experiences data anomalies due to slippage or wear, the system can still maintain measurement stability using data from the other speed measuring roller; furthermore, dynamic filtering of the speed measurement data based on the Kalman filter algorithm minimizes estimation errors, eliminates the influence of abrupt data jumps, and further improves measurement accuracy.

[0084] Below Figure 2 Based on the illustrated embodiments, combined with Figure 3 and Figure 4 The speed measurement method provided in the embodiments of this application will be further described.

[0085] Figure 3 This is a schematic diagram of the structure of a speed measuring system provided in an embodiment of this application, as shown below. Figure 3 As shown, it includes:

[0086] Physical cleaning device for the upper surface of conveyor belt: used to remove adhesive substances from the upper surface of conveyor belt to ensure that the upper surface of conveyor belt is clean.

[0087] Physical cleaning device for the underside of conveyor belt: used to remove adhesive substances from the underside of the conveyor belt, ensuring that the underside of the conveyor belt is clean.

[0088] Upper speed measuring roller (second speed measuring roller): It contacts the upper surface of the material belt and drives the speed measuring roller to roll through friction and pressure with the surface of the material belt.

[0089] Lower speed measuring roller (first speed measuring roller): It contacts the lower surface of the material belt and drives the speed measuring roller to roll through friction and pressure with the surface of the material belt.

[0090] Pressure sensor: measures the pressure applied to the upper or lower speed measuring roller.

[0091] Upper encoder: The actual running speed of the conveyor belt is measured by measuring the rotation of the upper speed measuring roller.

[0092] Lower encoder: measures the actual running speed of the conveyor belt by measuring the rotation of the upper speed measuring roller.

[0093] Automatically adjustable pressure module: The upper speed measuring roller is adjusted up and down by the control system.

[0094] Automatically adjustable upper module: The lower speed measuring roller is adjusted up and down by the control system.

[0095] Belt offset detection device: It monitors the belt offset in real time through sensor feedback and feeds the results back to the control system.

[0096] Automatic belt offset adjustment device: Controlled by the control system, it adjusts the left and right offset of the belt.

[0097] Figure 4 A flowchart illustrating a measurement method provided in this application embodiment. Figure 2 ,like Figure 4 As shown, it includes:

[0098] S401. Obtain the first pressure value of the first speed measuring roller and the second pressure value of the second speed measuring roller.

[0099] In some embodiments, such as Figure 3 As shown, the control system can acquire a first pressure value through a pressure sensor installed in the first speed measuring roller, and acquire a second pressure value through a pressure sensor installed in the second speed measuring roller.

[0100] S402. In the event of an abnormal first pressure value, control the operation of the adjustment device of the first speed measuring roller to restore the first pressure value to normal; and / or, in the event of an abnormal second pressure value, control the operation of the adjustment device of the second speed measuring roller to restore the second pressure value to normal.

[0101] In some embodiments, when the first pressure value and the second pressure value are obtained, it can be determined whether the first pressure value and the second pressure value are abnormal.

[0102] For example, if the first pressure value or the second pressure value is outside the preset pressure value range, that is, if the first pressure value or the second pressure value is higher than the upper limit of the preset pressure value or lower than the lower limit of the preset pressure value, then it can be determined that the first pressure value or the second pressure value is abnormal.

[0103] For example, if the first or second pressure value fluctuates significantly, it can be determined that the first or second pressure value is abnormal.

[0104] If an abnormality is found in the first pressure value or the second pressure value, the adjustment device of the first speed measuring roller can be controlled to operate so that the first pressure value is restored to normal; and / or, if the second pressure value is abnormal, the adjustment device of the second speed measuring roller can be controlled to operate so that the second pressure value is restored to normal.

[0105] For example, if the first pressure value is high, it may indicate that the contact between the first speed measuring roller and the conveyor belt is too tight. In this case, the automatically adjustable upper module can be controlled to move downward to reduce the first pressure value. If the first pressure value is low, it may indicate that the contact between the first speed measuring roller and the conveyor belt is not adequate. In this case, the automatically adjustable upper module can be controlled to move upward to increase the first pressure value.

[0106] When the second pressure value is high, it indicates that the contact between the second speed measuring roller and the conveyor belt is too tight. In this case, the automatically adjustable pressure module can be moved upward to reduce the second pressure value. When the second pressure value is low, it indicates that the contact between the second speed measuring roller and the conveyor belt is insufficient. In this case, the automatically adjustable pressure module can be moved downward to increase the second pressure value.

[0107] In some embodiments, if an anomaly is determined in the first pressure value and the second pressure value, the automatic adjusting downward module or the automatic adjusting upward module may be controlled in the following ways:

[0108] Taking the abnormal first pressure value as an example:

[0109] In one possible implementation, the difference between a first pressure value and a target pressure value can be obtained. Based on the mapping relationship between the difference and the displacement of the automatic adjustment upper module, the displacement distance of the automatic adjustment upper module can be determined. Based on the obtained displacement distance, the automatic adjustment upper module is controlled to move (upward or downward) to restore the first pressure value to the normal range. Here, the target pressure value is a value determined from a preset pressure range, and the mapping relationship between the difference and the displacement of the automatic adjustment upper module can be obtained through calibration based on experiments or prior knowledge.

[0110] In one possible implementation, the difference between the first pressure value and the target pressure value can be obtained. This difference is used as the input for adjustment and processed by PID control. The output is to automatically adjust the displacement distance of the upper module. Based on the obtained displacement distance, the upper module is automatically adjusted to perform actions so that the first pressure value is restored to the normal range.

[0111] It should be understood that when the second pressure value is abnormal, the method of determining the displacement distance of the automatic adjustment module based on the second pressure value is similar to that described above, and will not be repeated here.

[0112] S403. Obtain the first running speed of the conveyor belt measured by the first speed measuring roller, and the second running speed of the conveyor belt measured by the second speed measuring roller;

[0113] S404. Determine the target operating speed of the conveyor belt based on the first operating speed and the second operating speed.

[0114] The specific implementation method of steps S403-S404 in the embodiments of this application is the same as that of... Figure 2The specific implementation methods in the illustrated embodiments are similar and will not be described again here.

[0115] S405. Obtain the offset value of the conveyor belt.

[0116] In some embodiments, such as Figure 3 As shown, the control system can obtain the offset value of the conveyor belt through a belt offset detection device. For example, the belt offset detection device can be a photoelectric sensor or a displacement sensor.

[0117] S406. When the offset value indicates that the conveyor belt has deviated, control the offset adjustment device to operate in order to correct the conveyor belt.

[0118] In some embodiments, a conveyor belt offset can be determined when the offset value is not within a preset offset range. For example, an excessively large offset value may indicate that the conveyor belt is offset to the left, or an excessively large offset value may indicate that the conveyor belt is offset to the right. It should be understood that the correspondence between the offset value and the offset direction of the conveyor belt can be set based on actual needs.

[0119] In some embodiments, when a conveyor belt deviation is determined, the deviation adjustment device (i.e., the automatic belt deviation adjustment device) can be controlled to operate to correct the conveyor belt deviation. For example, when the conveyor belt deviates to the left, the deviation adjustment device can be controlled to move to the right to correct the conveyor belt deviation.

[0120] In some embodiments, the offset adjustment device may be controlled in the following ways:

[0121] In one possible implementation, the difference between the offset value and the target offset value can be obtained. Based on the mapping relationship between the difference and the displacement of the offset adjustment device, the displacement distance of the offset adjustment device can be determined. Based on the obtained displacement distance, the offset adjustment device can be controlled to move (left or right) to restore the offset to the normal range. Here, the target offset value is a value determined from a preset offset value range, and the mapping relationship between the difference and the displacement of the offset adjustment device can be obtained through calibration based on experiments or prior knowledge.

[0122] In one possible implementation, the difference between the offset value and the target offset value can be obtained, and this difference can be used as the input for adjustment. The PID controller is used to process the difference and output the displacement distance of the offset adjustment device. Based on the obtained displacement distance, the offset adjustment device is controlled to perform the action so that the offset value is restored to the normal range.

[0123] In some embodiments, to further improve the accuracy of monitoring the operating status of the speed measuring roller and reduce the impact of abnormalities in the speed measuring roller on the generation process, abnormality prediction of the speed measuring roller can also be performed.

[0124] For example, based on the operating parameters of the target speed measuring roller, anomaly prediction is performed on the target speed measuring roller; when an anomaly is predicted to occur in the target speed measuring roller, an anomaly alarm message is output.

[0125] The target speed measuring roller includes a first speed measuring roller and / or a second speed measuring roller; the operating parameters of the target speed measuring roller include a first operating speed, a second operating speed, a first pressure value, and a second pressure value.

[0126] For example, a pre-trained model can be used to process the operating parameters of the target speed measuring roller and predict the time when the target speed measuring roller may experience anomalies. The pre-trained model can be a neural network model constructed using a Long Short-Term Memory (LSTM) network.

[0127] For example, based on the operating parameters of the target speed measuring roller, it is predicted that the first speed measuring roller will experience an anomaly after 2 days.

[0128] When an anomaly is predicted in the first speed measuring roller, an anomaly warning message can be generated and sent to the corresponding maintenance personnel so that they can perform maintenance in advance. The anomaly warning message can include the identifier of the first speed measuring roller and the possible time of the anomaly.

[0129] The measurement method provided in this application, through a combination of a dual-speed-measuring roller redundancy design and a Kalman filter algorithm, effectively eliminates data errors caused by slippage or jumps, ensuring the stability and accuracy of speed data. By dynamically adjusting the speed-measuring roller state using a pressure sensor and an offset detection device, it avoids measurement deviations caused by pressure fluctuations or material offsets, enabling online calibration and reducing downtime for maintenance. Furthermore, by predicting equipment failures and providing remote early warnings through data analysis, it improves maintenance efficiency and reduces the risk of sudden failures. In summary, the technical solution of this application, through algorithm optimization, dynamic compensation, and system integration, achieves high precision, high stability, and intelligent upgrading of the speed measurement system, effectively meeting the stringent requirements of modern industry for continuous production processes.

[0130] This application also provides a speed measuring device.

[0133] The processing module 502 is used to determine the target running speed of the conveyor belt based on the first running speed and the second running speed.

[0134] In some embodiments, the processing module 502 is configured to, when it is determined that the first operating speed and the second operating speed are within the normal range, perform filtering processing on the first operating speed and the second operating speed respectively to obtain a third operating speed and a fourth operating speed; and determine a target operating speed based on the third operating speed and the fourth operating speed.

[0135] In some embodiments, the processing module 502 is configured to filter the second running speed to obtain a target running speed if the first running speed is determined to be abnormal.

[0136] In some embodiments, the acquisition module 501 is used to acquire a first pressure value of the first speed measuring roller and a second pressure value of the second speed measuring roller.

[0137] In some embodiments, the processing module 502 is configured to, in the event of an abnormal first pressure value, control the operation of the adjustment device of the first speed measuring roller to restore the first pressure value to normal; and / or, in the event of an abnormal second pressure value, control the operation of the adjustment device of the second speed measuring roller to restore the second pressure value to normal.

[0138] In some embodiments, the first speed measuring roller and the second speed measuring roller are disposed opposite to each other on the upper and lower sides of the conveyor belt.

[0139] In some embodiments, the acquisition module 501 is used to acquire the offset value of the conveyor belt.

[0140] In some embodiments, the processing module 502 is configured to control the offset adjustment device to operate in order to correct the conveyor belt when the offset value indicates that the conveyor belt has deviated.

[0141] In some embodiments, the processing module 502 is used to predict anomalies in the target speed measuring roller based on the operating parameters of the target speed measuring roller; the target speed measuring roller includes a first speed measuring roller and / or a second speed measuring roller; when an anomaly is predicted in the target speed measuring roller, an anomaly warning message is output.

[0143] This application also provides an electronic device.

[0144] Figure 6 This is a schematic diagram of the structure of the electronic device 60 provided in the embodiments of this application. The electronic device 60 can be a control system as shown in any of the above embodiments, such as... Figure 6 As shown, the electronic device may include: a transceiver 601, a processor 602, and a memory 603.

[0145] The processor 602 executes computer execution instructions stored in the memory, causing the processor 602 to perform the scheme in the above embodiments. The processor 602 can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components.

[0146] The memory 603 is connected to the processor 602 via the system bus and completes communication between them. The memory 603 is used to store computer program instructions.
