[0051] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0052] like Figures 1 to 4 As shown, according to the first aspect of the embodiment of the present disclosure, a conveyor belt speed detection device 100 is proposed, comprising: a bracket portion 110; a wheel portion 120, which is arranged on the bracket assembly, the wheel portion 120 is used to abut against the working surface of the conveyor belt 100' to be detected, and is suitable for rotating under the drive of the conveyor belt 100' to be detected; a detection portion 130, which is used to obtain the rotation speed information of the wheel portion 120, and determine the belt speed information of the conveyor belt 100' to be detected based on the rotation speed information.

[0053] The belt speed detection device 100 of the conveyor belt provided by the embodiment of the present disclosure includes the aforementioned bracket part 110, the wheel part 120 and the detection part 130. In practical applications, the aforementioned belt speed detection device 100 can be applied to the belt speed detection operation of the conveyor belt of the belt conveyor equipment, or used as a component of the belt conveyor equipment. The aforementioned belt conveyor equipment can be but not limited to the belt conveyor equipment used to transport alumina to the aluminum electrolytic cell. Based on the aforementioned setting, the belt speed detection device 100 can use the bracket part 110 to support the wheel part 120 to ensure the installation stability and reliability of the wheel part 120; the wheel part 120 can be used to abut against the working surface of the conveyor belt 100' to be detected, so that the wheel part 120 forms a contact relationship with the aforementioned working surface. It can be understood that the aforementioned working surface refers to the side surface of the conveyor belt 100' to be detected that is away from the driving roller 200', so that during the movement of the conveyor belt, the wheel part 120 can be subjected to the force applied by the aforementioned working surface to drive the wheel part 120 to rotate. The detection unit 130 can obtain and determine the belt speed information of the conveyor belt 100' to be detected based on the rotation speed information of the wheel unit 120, so as to facilitate judging the running condition of the conveyor belt to be detected based on the belt speed information determined by the detection unit 130 in actual application, thereby improving the control convenience of the belt conveyor equipment.

[0054] It should be noted that belt conveyor equipment usually includes a driving roller and a conveyor belt, and the aforementioned driving roller is used to apply a driving force to the conveyor belt to make the conveyor belt move. In actual applications, the conveyor belt sometimes slips, resulting in the asynchronous movement of the conveyor belt and the driving roller. Accordingly, the corresponding relationship between the actual belt speed of the conveyor belt and the rotation speed of the driving roller will change. In addition, since the driving roller tends to maintain the previous rotation state when the conveyor belt slips, it is difficult to determine the actual belt speed and operating status of the conveyor belt based on the rotation speed of the driving roller, which increases the safety risks and control difficulties of the belt conveyor equipment.

[0055] Compared with the aforementioned method of determining the belt speed of the conveyor belt based on the rotation speed of the driving roller, the belt speed detection device 100 provided in the embodiment of the present disclosure can, based on the aforementioned setting, enable the wheel portion 120 to be driven and rotated by the conveyor belt 100' to be detected, and determine the aforementioned belt speed information based on the rotation speed information of the wheel portion 120, so that when the conveyor belt 100' to be detected and the driving roller 200' move synchronously, the wheel portion 120 can be driven by the conveyor belt 100' to be detected to rotate stably, and accordingly, the aforementioned belt speed information determined by the detection unit 130 can relatively accurately represent the actual belt speed of the conveyor belt 100' to be detected, which is the belt speed of the conveyor belt 100'. It provides a reliable reference for the regulation of the conveyor belt 100' to be detected; when the movement of the conveyor belt 100' to be detected is not synchronized with the movement of the driving roller 200', the corresponding relationship between the belt speed of the conveyor belt 100' to be detected and the rotation speed of the driving roller 200' will change accordingly, resulting in changes in the belt speed of the conveyor belt and the rotation speed of the wheel part 120, and then the belt speed information determined by the detection part 130 based on the aforementioned rotation speed information will also change, which can facilitate the operating personnel to timely discover and deal with the fault of the conveyor belt 100' to be detected through the changes in the aforementioned belt speed information, and provide guarantee for the safety and regulation convenience of the belt conveyor equipment. Based on this, the belt speed detection device 100 provided in the embodiment of the present disclosure can detect the belt speed information of the conveyor belt, and the detected belt speed information can provide a reliable reference for judging the actual operating state of the conveyor belt, which is conducive to ensuring the safety and regulation convenience of the belt conveyor equipment.

[0056] It can be understood that, in actual application, the circumferential side of the aforementioned wheel portion 120 can abut against the aforementioned working surface, and the axial direction of the wheel portion 120 intersects with the belt length direction of the conveyor belt 100' to be detected, so that the force applied by the aforementioned working surface to the wheel portion 120 forms a torque driving the wheel portion 120 to rotate, thereby making the wheel portion 120 suitable for rotating under the drive of the conveyor belt 100' to be detected; accordingly, the belt speed of the conveyor belt 100' to be detected can be determined based on the correspondence between the aforementioned rotational speed information and the aforementioned belt speed information and the aforementioned rotational speed information. It can be understood that the correspondence between the aforementioned rotational speed information and the aforementioned belt speed information can be obtained based on the analysis of the transmission relationship between the conveyor belt 100' to be detected and the wheel portion 120, which will not be explained in detail here. Exemplarily, the circumferential side of the aforementioned wheel portion 120 can abut against the aforementioned working surface, and the axial direction of the aforementioned wheel portion 120 can be arranged parallel to the belt width direction of the conveyor belt 100' to be detected, so as to simplify the transmission relationship between the wheel portion 120 and the conveyor belt, and improve the transmission efficiency between the conveyor belt 100' to be detected and the wheel portion 120. Accordingly, the linear velocity of the wheel portion 120 can be used to characterize the belt speed of the conveyor belt 100' to be detected.

[0057] It is understandable that the conveyor belt may have a transmission surface and the aforementioned working surface, and the aforementioned transmission surface is used to connect the driving roller 200'. Compared with the method of setting the wheel part 120 to abut against the aforementioned transmission surface, the present disclosure sets the wheel part 120 to abut against the working surface of the conveyor belt 100' to be detected, which can reduce the wear of the transmission surface on the one hand, thereby ensuring the contact reliability between the conveyor belt and the driving roller 200', and providing guarantee for the stable and reliable operation of the conveyor belt; on the other hand, if the wheel part 120 is loosened from the bracket part 110, it can be avoided that the wheel part 120 falls on the aforementioned transmission surface and is moved to the roller by the conveyor belt 100' to be detected, which is conducive to reducing the risk of damage to the roller or conveyor belt of the belt conveyor equipment.

[0058] It can be understood that the aforementioned rotation speed information may include a rotation speed value and a rotation speed direction; the aforementioned belt speed information may include a belt speed value and a belt speed direction.

[0059] It should be noted that Figure 1 The dashed straight line with arrows and the dashed curve with arrows in the figure respectively represent the belt speed direction of the conveying section of the conveyor belt 100' to be detected and the direction of the driving roller 200'. It can be understood that the conveyor belt 100' to be detected can have a conveying section and a return section 101', wherein the conveying section is used to carry materials and the belt speed direction is the conveying direction, and the return section 101' is located below the conveying section and the belt speed direction is opposite to the conveying direction.

[0060] like Figure 2 and Figure 3 As shown, in some examples, the wheel portion 120 includes: a fixed shaft 121, which is arranged on the bracket portion 110; a wheel body 122, which is rotatably sleeved on the fixed shaft 121; wherein the circumferential side of the wheel body 122 is used to abut against the working surface of the return section 101' of the conveyor belt 100' to be inspected, and the wheel body 122 is suitable for rotating under the drive of the conveyor belt 100' to be inspected.

[0061] In this technical solution, the wheel part 120 may include the aforementioned fixed shaft 121 and the aforementioned wheel body 122; based on the aforementioned setting, on the one hand, the detection part 130 can obtain the rotation speed information of the wheel body 122 and determine the belt speed information of the conveyor belt 100' to be detected according to the aforementioned rotation speed information, so as to facilitate the judgment of the running condition of the conveyor belt to be detected based on the belt speed information determined by the detection part 130 in actual application, thereby improving the control convenience of the belt conveyor equipment; on the other hand, by setting the peripheral side of the wheel body 122 to abut the working surface of the aforementioned return section 101', the wheel part 120 can be located below the conveyor belt 100' to be detected in actual application, so that if the wheel part 120 is loosened from the bracket part 110, it can be avoided that the wheel part 120 falls on the aforementioned conveyor belt 100' to be detected, and is moved to the roller or silo by the conveyor belt 100' to be detected, which is beneficial to reduce the risk of damage to the roller or conveyor belt of the belt conveyor equipment and prevent the mixing of foreign matter into the material transported by the conveyor belt 100' to be detected.

[0062] It should be noted that Figure 2 The bracket portion 110 is hidden.

[0063] Exemplarily, the axial direction of the aforementioned fixed shaft 121 is arranged along the belt width direction of the conveyor belt 100 ′ to be inspected.

[0064] like Figure 2 and Figure 4 As shown, in some examples, the detection unit 130 includes: a first detection member 131, the wheel unit 120 also includes a trigger member 123 arranged on the wheel body 122 and suitable for synchronously rotating with the wheel body 122, the trigger member 123 has a first working position along the rotation direction, and the first detection member 131 is configured to generate a first trigger information when the trigger member 123 is located at the first working position; a first processing module, used to determine the rotation speed value of the wheel body 122 according to the generation time interval of two adjacent first trigger information, and the rotation speed information includes the rotation speed value; a second processing module, used to determine the belt speed value of the conveyor belt 100' to be detected according to the rotation speed value, and the belt speed information includes the belt speed value.

[0065] In this technical solution, the detection unit 130 may include the aforementioned first detection member 131, a first processing module and a second processing module, and the wheel unit 120 may also include the aforementioned trigger member 123; based on the aforementioned setting, the aforementioned trigger member 123 may rotate synchronously with the aforementioned wheel body 122, and the position of the trigger member 123 in the rotation direction may change during the rotation process. Accordingly, the trigger member 123 may have the aforementioned first working position in the rotation direction, and when it is in the aforementioned first working position, it can trigger the aforementioned first detection member 131, so that the first detection member 131 generates the aforementioned first trigger information. The trigger member 123 will repeatedly pass through the aforementioned first working position during the process of rotating with the wheel body 122. Accordingly, the first processing module can generate a first trigger information each time the trigger member 123 is in the first working position. The aforementioned first processing module signal is connected between the aforementioned first detection component 131 and the aforementioned second processing module, and can receive the first trigger information generated by the aforementioned first detection component 131. The first processing module can obtain the generation time of each received first trigger information, and determine the rotation speed value of the wheel body 122 according to the generation time interval of two adjacent first trigger information; the aforementioned second processing module can receive the aforementioned rotation speed value, and determine the belt speed value of the conveyor belt 100' to be detected according to the aforementioned rotation speed value, so as to facilitate the detection of the belt speed of the conveyor belt 100' to be detected in actual applications, and facilitate the operating personnel to judge whether the conveyor belt 100' to be detected has abnormal belt speed according to the aforementioned belt speed value.

[0066] It can be understood that the two adjacent first trigger information mentioned above refer to two first trigger information that are adjacent in generation time. The trigger member 123 will rotate a certain angle in the process of triggering the first detection member 131 twice in succession. If the angle rotated by the trigger member 123 in the process of triggering the first detection member 131 twice in succession is taken as the trigger rotation amount, then the aforementioned rotation speed value is the ratio of the trigger rotation amount to the aforementioned generation time interval. The number of the aforementioned first working positions may be one or more; in the case where the aforementioned first working positions are multiple, the aforementioned trigger rotation amount is 360°; in the case where the aforementioned first working positions are multiple, the multiple first working positions may be arranged at intervals along the aforementioned rotation direction, and a first angle is formed between two adjacent first working positions, and the aforementioned trigger rotation amount is the aforementioned first angle, and the aforementioned first angle is less than 360°.

[0067] It can be understood that, based on the above-mentioned setting, when the rotating wheel body 122 is driven by the conveyor belt 100' to be detected, the linear velocity value of the circumference of the rotating wheel body 122 is positively correlated with the belt speed value of the conveyor belt 100' to be detected. Accordingly, the second processing module can determine the belt speed value according to the circumference of the rotating wheel body 122 and the above-mentioned rotation speed value. For example, when the axial direction of the above-mentioned fixed shaft 121 is arranged along the bandwidth direction of the conveyor belt 100' to be detected, the above-mentioned belt speed value is equal to the product of the circumference of the rotating wheel body 122 and the above-mentioned rotation speed value.

[0068] Exemplarily, the detection portion 130 may further include a detection disk 134, which is fixedly mounted on the fixed shaft 121, the first detection member 131 is disposed on the detection disk 134, and the detection end of the first detection member 131 is facing the rotating wheel body 122, the trigger member 123 is disposed at one end of the rotating wheel body 122 facing the detection disk 134, the first working position is the position when the trigger member 123 is axially opposite to the detection end of the first detection member 131 along the fixed shaft 121, the trigger member 123 may be a metal baffle, the first detection member 131 may be a first proximity switch, and the first proximity switch is suitable for being triggered when the trigger member 123 is located in the first working position, and generating the first trigger information.

[0069] In some examples, the conveyor belt speed detection device 100 further includes: a first alarm unit connected to the detection unit 130, and configured to generate a first alarm message when the belt speed value exceeds a preset belt speed interval.

[0070] In this technical solution, the belt speed detection device 100 also includes the aforementioned first alarm unit; based on the aforementioned setting, the belt speed detection device 100 can generate a first alarm message through the first alarm unit when the belt speed value exceeds the preset belt speed range, so as to prompt the operator of the detected abnormal belt speed information, so as to facilitate the operator to promptly perform fault detection and processing of the conveyor belt 100' to be detected, which is beneficial to improving the safety and reliability of the belt conveyor equipment.

[0071] It is understandable that the aforementioned first alarm unit can be connected to the second processing module via a signal.

[0072] It is understandable that the aforementioned preset belt speed range can be set based on the conveying demand in actual application, and no excessive restrictions are made here.

[0073] It can be understood that the aforementioned first alarm unit may include a first optical warning element, which is used to generate a first optical alarm information when the belt speed value exceeds the preset belt speed range, and the aforementioned first alarm information includes the aforementioned first optical alarm information. Exemplarily, the aforementioned first optical warning element may be but not limited to a display, a warning light, etc., and the aforementioned first optical warning information may be in the form of but not limited to light, text, graphics, etc.; and / or, the aforementioned first alarm unit may include a first acoustic warning element, which is used to generate a first acoustic alarm information when the belt speed value exceeds the preset belt speed range, and the aforementioned first alarm information includes the aforementioned first acoustic alarm information. Exemplarily, the aforementioned first acoustic warning element may be but not limited to a speaker, a buzzer, etc., and the aforementioned first acoustic warning information may be in the form of but not limited to voice, buzzer, etc.

[0074] like Figure 2 and Figure 4 As shown, in some examples, the detection unit 130 also includes: a second detection member 132, the trigger member 123 also has a second working position along the rotation direction, and the second detection member 132 is configured to generate second trigger information when the trigger member 123 is located at the second working position; a third detection member 133, the trigger member 123 also has a third working position along the rotation direction, and the third detection member 133 is configured to generate third trigger information when the trigger member 123 is located at the third working position, and the first working position, the second working position and the third working position are different from each other; a third processing module, used to determine the rotation direction of the wheel body 122 according to the generation time of the adjacent first trigger information, the second trigger information and the third trigger information, and the rotation speed information also includes the rotation speed direction; a fourth processing module, used to determine the belt speed direction of the conveyor belt 100' to be detected according to the rotation speed direction, and the belt speed information also includes the belt speed direction.

[0075] In this technical solution, the detection unit 130 may also include the aforementioned second detection member 132, the third detection member 133, the third processing module and the fourth processing module; based on the aforementioned setting, the aforementioned trigger member 123 can trigger the aforementioned second detection member 132 and the aforementioned third detection member 133 when it is in the aforementioned second working position and in the aforementioned third working position, so that the second detection member 132 and the third detection member 133 generate the aforementioned second trigger information and the aforementioned third trigger information respectively, and the trigger member 123 can pass through the aforementioned first working position, the second working position and the third working position in a certain time sequence during the rotation of the rotating wheel body 122, so that the generation time of the aforementioned first trigger information, the second trigger information and the third trigger information will form a certain time sequence relationship; the aforementioned third processing module signal is connected to the aforementioned first detection member 131, the second detection member 132 and the aforementioned third detection member 133 when it is in the aforementioned second working position The detection member 132 and the third detection member 133 can receive the aforementioned first trigger information, the second trigger information and the third trigger information. The third processing module can obtain the generation time of each received trigger information, and determine the time sequence when the trigger member 123 passes through the aforementioned first working position, the second working position and the third working position according to the generation time of the adjacently generated first trigger information, the second trigger information and the third trigger information, thereby determining the rotational speed direction of the wheel body 122; the aforementioned fourth processing module signal is connected to the aforementioned third processing module and can receive the aforementioned rotational speed direction, thereby determining the belt speed direction of the conveyor belt 100' to be detected according to the aforementioned rotational speed direction, so that the operating personnel can judge whether the conveyor belt 100' to be detected has reverse movement based on the aforementioned belt speed direction, thereby providing guarantee for the stable and reliable operation and stable fault handling of the belt conveyor equipment.

[0076] It can be understood that the aforementioned adjacently generated first trigger information, second trigger information and third trigger information refer to the first trigger information, second trigger information and third trigger information that are adjacent in generation time.

[0077] It can be understood that, based on the above configuration, the first working position, the second working position and the third working position are arranged in sequence along a certain arrangement direction around the axis of the fixed shaft 121. Figure 3Taking the perspective shown as an example, the aforementioned arrangement direction can be clockwise or counterclockwise; when the generation time sequence of the adjacently generated first trigger information, the second trigger information and the third trigger information complies with the aforementioned arrangement sequence, it can be determined that the wheel body 122 and the trigger member 123 rotate along the aforementioned arrangement direction; when the generation time sequence of the adjacently generated first trigger information, the second trigger information and the third trigger information is opposite to the aforementioned arrangement sequence, it can be determined that the wheel body 122 and the trigger member 123 rotate in the direction opposite to the aforementioned arrangement direction. The rotational speed directions of the wheel body 122 and the trigger member 123 are the same, and are both related to the direction of the force applied to the wheel body 122 by the conveyor belt 100' to be detected, and the aforementioned force direction is consistent with the belt speed direction of the return section 101' of the conveyor belt 100' to be detected. Based on this, when the rotational speed direction of the aforementioned wheel body 122 is determined, the belt speed direction of the return section 101' of the conveyor belt 100' to be detected and the belt speed direction of the conveying section can be obtained based on the aforementioned rotational speed direction.

[0078] by Figure 3 Taking the perspective shown as an example, it is assumed that the first working position, the second working position and the third working position can be arranged in sequence in the clockwise direction around the fixed axis 121, and the generation time of the first trigger information, the second trigger information and the third trigger information generated adjacently is the first. If the generation time of the third trigger information is the last among the first trigger information, the second trigger information and the third trigger information generated adjacently, it can be determined that the trigger member 123 and the wheel body 122 are in a state of synchronous clockwise rotation, and accordingly, the belt speed direction of the return section 101' of the conveyor belt 100' to be detected is from left to right; if the generation time of the second trigger information is the last among the first trigger information, the second trigger information and the third trigger information generated adjacently, it can be determined that the trigger member 123 and the wheel body 122 are in a state of synchronous counterclockwise rotation, and accordingly, the belt speed direction of the return section 101' of the conveyor belt 100' to be detected is from right to left.

[0079] Exemplarily, the second detection member 132 and the third detection member 133 can both be arranged on the detection disk 134, and the detection ends of the second detection member 132 and the third detection member 133 are both facing the rotating wheel body 122; the first detection member 131, the second detection member 132 and the third detection member 133 are arranged at intervals around the fixed axis 121; the second working position is the position when the trigger member 123 is opposite to the detection end of the second detection member 132 along the axial direction of the fixed axis 121, and the third working position is the position when the trigger member 123 is opposite to the detection end of the third detection member 133 along the axial direction of the fixed axis 121; the second detection member 132 can be a second proximity switch, and the third detection member 133 can be a third proximity switch; the second proximity switch is suitable for being triggered when the trigger member 123 is located in the second working position, and generating the second trigger information; the third proximity switch is suitable for being triggered when the trigger member 123 is located in the third working position, and generating the third trigger information.

[0080] In some examples, the conveyor belt speed detection device 100 further includes: a second alarm unit connected to the detection unit 130, and configured to generate a second alarm message when the belt speed direction is different from a preset direction.

[0081] In this technical solution, the belt speed detection device 100 also includes the aforementioned second alarm unit; based on the aforementioned setting, the belt speed detection device 100 can generate a second alarm message through the second alarm unit when the belt speed direction is different from the preset direction, so as to prompt the operator of the detected abnormal belt speed information, so as to facilitate the operator to promptly check and deal with the reversal phenomenon of the conveyor belt 100' to be detected, which is beneficial to improving the safety and reliability of the belt conveyor equipment.

[0082] It is understandable that the aforementioned second alarm unit can be connected to the fourth processing module via a signal.

[0083] It can be understood that the aforementioned belt speed direction is the belt speed direction of the aforementioned return segment 101 ′, and the aforementioned preset direction is the preset direction of the aforementioned return segment 101 ′.

[0084] It is understandable that the aforementioned preset direction can be set based on the transportation demand in actual application, and no excessive restrictions are made here.

[0085] It can be understood that the aforementioned second alarm unit may include a second optical warning element, which is used to generate a second optical alarm information when the belt speed value exceeds the preset belt speed range, and the aforementioned second alarm information includes the aforementioned second optical alarm information.

Exemplarily, the aforementioned second acoustic warning element may be but not limited to a speaker, a buzzer, etc., and the aforementioned second acoustic warning information may be in the form of but not limited to voice, buzzer, etc.

[0086] Exemplarily, the detection unit 130 may include a PLC (Programmable Logic Controller), which includes the first processing module, the second processing module, the third processing module, and the fourth processing module. Taking the belt speed detection device 100 as a component of a belt conveyor device for conveying alumina to an aluminum electrolytic cell as an example, the PLC may send the belt speed information to a data monitoring interface machine in a central control room through a network, thereby realizing functions such as real-time display of the belt speed value and belt speed direction measurement data of the conveyor belt 100' to be detected, over-limit alarm, etc.

[0088] In this technical solution, the bracket portion 110 may include the aforementioned base 111 and the aforementioned elastic member 112; based on the aforementioned setting, the bracket portion 110 can apply the aforementioned force to the wheel portion 120 through the elastic member 112, so that the wheel portion 120 can be more closely abutted against the aforementioned working surface, thereby reducing the risk of separation of the wheel portion 120 from the working surface, which is conducive to the wheel portion 120 receiving the force applied by the aforementioned working surface more stably, so as to follow the synchronous movement of the conveyor belt 100' to be detected, thereby providing a guarantee for the accurate determination of the belt speed information.

[0089] Exemplarily, the bracket portion 110 may further include a connecting rod 113, the connecting rod 113 is hinged to the base 111, the elastic member 112 is connected between the connecting rod 113 and the base 111, the wheel portion 120 is arranged on the connecting rod 113, and the elastic member 112 is used to apply a force close to the working surface to the wheel portion 120 through the connecting rod 113.

[0092] Step S502: Determine the belt speed information of the conveyor belt 100 ′ to be detected according to the rotation speed information. It is understandable that the belt speed information can be determined by the detection unit 130 .

[0093] In summary, the belt speed detection method provided in the embodiment of the present disclosure can detect the belt speed information of the conveyor belt 100' to be detected based on the above-mentioned belt speed detection device 100. When the conveyor belt 100' to be detected moves synchronously with the driving roller 200', the pulley portion 120 can stably rotate under the drive of the conveyor belt 100' to be detected. Accordingly, the aforementioned belt speed information can relatively accurately characterize the actual belt speed of the conveyor belt 100' to be detected, and provide a reliable reference for the regulation of the belt conveyor equipment; when the movement of the conveyor belt 100' to be detected is not synchronized with the movement of the driving roller 200', the corresponding relationship between the belt speed of the conveyor belt 100' to be detected and the rotation speed of the driving roller will change accordingly, resulting in changes in the belt speed of the conveyor belt and the rotation speed of the pulley portion 120, and then the belt speed information determined based on the aforementioned rotation speed information will also change, which can facilitate the operating personnel to timely discover and handle the fault of the conveyor belt 100' to be detected through the changes in the aforementioned belt speed information, and provide a guarantee for the convenience of safety regulation of the belt conveyor equipment. Based on this, the belt speed detection method provided in the embodiment of the present disclosure can detect the belt speed information of the conveyor belt, and the detected belt speed information can provide a reliable reference for judging the actual operating status of the conveyor belt, which is conducive to ensuring the safety and control convenience of the belt conveyor equipment.
