Description

Technical Field

[0001] This invention relates to the field of production control technology, and in particular to a method and related equipment for alarm control of disc shear edge blocking. Background Technology

[0002] In a steel rolling production line, a disc shear is a device used to continuously cut off the edges of a strip steel. A disc shear typically consists of two pairs of cutters fixed to a drive shaft. These two pairs of cutters are installed on opposite sides of the strip steel—the operating side and the drive side—and are used to shear the edges of the strip steel.

[0003] Currently, existing technologies generally rely on additional hardware to collect relevant data in order to determine the jamming status of the disc shears. However, this method involves complex hardware installation processes, relatively difficult and costly maintenance, and is not suitable for situations where there is no space for hardware installation in the existing equipment. Summary of the Invention

[0004] This application provides a disc shear edge blocking alarm control method and related equipment that can determine the disc shear jamming situation without installing additional hardware, simplifying operation, reducing costs, and is applicable to situations where existing equipment has no space for hardware installation.

[0005] Firstly, this application proposes a method for controlling the edge jamming alarm of a disc shear, comprising: acquiring information on the circumference of the disc shear blade and information on the disc shear's jamming stroke, wherein the disc shear's jamming stroke information is the cumulative stroke information of the disc shear from jamming to returning to normal, and the cumulative stroke information is the circumferential rolling distance information; if the disc shear's jamming stroke information is greater than or equal to the disc shear blade circumference information, determining that the disc shear jamming type is a continuous jamming type, and outputting an edge jamming alarm; if the disc shear's jamming stroke information is less than the disc shear blade circumference information, determining that the disc shear jamming type is an intermittent jamming type, recording the number of intermittent jammings of the disc shear, and outputting an edge jamming reminder.

[0006] In some feasible implementations, when the disc shear jamming type is intermittent jamming, the above method further includes: acquiring the cumulative number of times the disc shear experiences intermittent jamming; acquiring the disc shear's lifespan mileage information when the cumulative number of intermittent jammings is greater than a first preset threshold and less than or equal to a second preset threshold; outputting a blockage alarm when the lifespan mileage information is greater than a preset lifespan mileage threshold; and outputting a blockage alarm when the cumulative number of intermittent jammings is greater than the second preset threshold, wherein the first preset threshold is less than the second preset threshold.

[0007] In some feasible implementations, the above method further includes: acquiring scan cycle information, correction parameter information, and running time information of the disc shear from the programmable logic controller, wherein the correction parameter information is positively correlated with the strip thickness information; determining the running mileage information of the disc shear within the scan cycle based on the scan cycle information, correction parameter information, and speed information of the disc shear; determining the number of scan cycles based on the running time information and scan cycle information of the disc shear; and determining the lifespan mileage information based on the running mileage information and the number of scan cycles information.

[0008] In some feasible implementations, the above method further includes: receiving a unit speed-up command or a shutdown command within a preset time when a blockage alarm is output; controlling the unit to speed up when a unit speed-up command is received within the preset time; and controlling the unit to speed down until shutdown when no unit speed-up command is received within the preset time or when a shutdown command is received.

[0009] In some feasible implementations, the above method further includes: determining unit crawling stage information based on unit speed information, wherein the unit crawling stage information includes first stage information, second stage information and third stage information, the unit speed information corresponding to the first stage information is less than the unit speed information corresponding to the second stage information, the unit speed information corresponding to the second stage information is less than the unit speed information corresponding to the third stage information, the first preset number threshold corresponding to the second stage is less than the first preset number threshold corresponding to the first stage, and the second preset number corresponding to the second stage is less than the second preset number corresponding to the first stage.

[0010] In some feasible implementations, the above method further includes: when an edge blockage alarm is output and the unit creep stage information is in the first stage, controlling the unit speed to increase to the unit speed corresponding to the second stage information to eliminate the edge blockage abnormality; when an edge blockage alarm is output and the unit creep stage information is in the second stage, controlling the unit speed to increase to the unit speed corresponding to the third stage information to eliminate the edge blockage abnormality; when an edge blockage alarm is output and the unit creep stage information is in the third stage, controlling the unit speed to decrease to eliminate the edge blockage abnormality.

[0011] In some feasible implementations, when the crawling stage information is third stage information, the above method further includes: acquiring the duration information of continuous jamming; outputting an edge jamming alarm when the duration information is greater than a preset duration threshold; and / or acquiring the speed information of the disc shears, outputting an edge jamming alarm when the speed information is less than a preset speed threshold, wherein the speed information includes: speed information on the transmission side and / or speed information on the operation side.

[0012] Secondly, this application proposes a disc shear edge-clogging alarm control device, applicable to the disc shear edge-clogging alarm control method described above. The disc shear edge-clogging alarm control device includes: an acquisition unit, used to acquire disc shear blade circumference information and disc shear jamming stroke information, wherein the disc shear jamming stroke information is the cumulative stroke information of the disc shear from jamming to returning to normal, and the cumulative stroke information is circumferential rolling distance information; a determination unit, used to determine the disc shear jamming type as continuous jamming type when the disc shear jamming stroke information is greater than or equal to the disc shear blade circumference information, and output an edge-clogging alarm; and a recording unit, used to determine the disc shear jamming type as intermittent jamming type when the disc shear jamming stroke information is less than the disc shear blade circumference information, record the number of intermittent jamming events of the disc shear, and output an edge-clogging reminder.

[0013] Thirdly, this application 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 disk shearing edge blocking alarm control method as described in any of the preceding claims.

[0014] Fourthly, this application proposes a storage medium on which program instructions are stored, which, when executed, are used to perform the disk shearing and blocking alarm control method as described in any of the preceding claims.

[0015] The disc shear edge-clogging alarm control method proposed in this application includes: acquiring the disc shear blade circumference information and the disc shear jamming stroke information, wherein the disc shear jamming stroke information is the cumulative stroke information of the disc shear from jamming to returning to normal, and the cumulative stroke information is the circumferential rolling distance information; when the disc shear jamming stroke information is greater than or equal to the disc shear blade circumference information, the disc shear jamming type is determined to be continuous jamming type, and an edge-clogging alarm is output; when the disc shear jamming stroke information is less than the disc shear blade circumference information, the disc shear jamming type is determined to be intermittent jamming type, the number of intermittent jamming events is recorded, and an edge-clogging reminder is output. This application can accurately determine the disc shear jamming type using disc shear and production line data without installing additional hardware equipment, accurately output edge-clogging alarms or edge-clogging reminders based on the disc shear jamming type, and count the number of times the disc shear jams intermittently, which is beneficial for accurately controlling the intermittent jamming situation of the disc shear and providing data support for subsequent processing procedures.

[0023] Currently, existing technologies generally rely on additional hardware to collect relevant data in order to determine the jamming status of the disc shears. However, this method involves complex hardware installation processes, relatively difficult and costly maintenance, and is not suitable for situations where there is no space for hardware installation in the existing equipment.

[0024] In view of this, the embodiments of this application provide a disc shear edge blocking alarm control method and related equipment that can determine the disc shear jamming situation without installing additional hardware, simplifying operation, reducing costs, and is also applicable to situations where there is no space for hardware installation in existing equipment.

[0025] According to a first aspect of the embodiments of this application, this application proposes a disc shear edge-blocking alarm control method. It should be noted that this application is applicable to active disc shears, that is, disc shears driven by a motor to rotate and thus perform shearing on strip steel. Figure 1 This is a flowchart illustrating a disc shearing edge-blocking alarm control method 100 provided in an embodiment of this application. Figure 1 As shown, the above-mentioned disc shearing edge alarm control method 100 may include the following steps:

[0026] Step S110: Obtain the circumference information of the disc shear blade and the disc shear jamming stroke information. The disc shear jamming stroke information is the cumulative stroke information of the disc shear from jamming to returning to normal. The cumulative stroke information is the circumferential rolling distance information.

[0027] It should be noted that before performing step S110 above, the following steps can be used to determine whether the disc shear is jammed:

[0028] The torque and speed information of the disc shear are acquired. If the torque information is greater than or equal to a preset torque threshold, and the speed information is less than a preset unit speed threshold, then the disc shear is determined to be jammed. Specifically, the torque information can be determined online by a frequency converter. The speed information can be determined based on the motor linear speed information. Specifically, the motor linear speed information can be determined based on the motor's rotational speed. It should be noted that the preset torque threshold can be determined based on motor parameters, and the preset unit speed threshold can be determined based on production line parameters. For example, the preset torque threshold can be 100% of the motor output torque, and the preset unit speed information can be 70% of the unit linear speed, strip drive speed, or strip drawing speed.

[0029] It should be noted that the active disc shears are driven by two variable frequency motors. The torque information of the disc shears mentioned above can include: torque information on the drive side and / or torque information on the operating side. The speed information of the disc shears mentioned above can include: speed information on the drive side and / or speed information on the operating side.

[0030] Specifically, if the torque information on the drive side of the disc shear is greater than or equal to 100% of the output torque of the drive-side motor, and the speed information on the drive side of the disc shear is less than 70% of the unit speed, then the disc shear is determined to be jammed. Alternatively, if the torque information on the operating side of the disc shear is greater than or equal to 100% of the output torque of the operating-side motor, and the speed information on the operating side of the disc shear is less than 70% of the unit speed, then the disc shear is determined to be jammed.

[0031] It should be noted that after determining that the disc shear is jammed, step S110 can be executed.

[0032] For example, the circumference information of the disc shear blade can be determined based on the diameter of the disc shear blade. Specifically, the circumference information of the disc shear blade can be determined according to the following formula:

[0033] L _per =πd (1)

[0034] Among them, L _per d is the circumference of the disc shear blade, and d is the diameter of the disc shear blade.

[0035] Specifically, when the diameter d of the disc shear blade is 300mm, the circumference L of the disc shear blade is... _per It is approximately 942mm.

[0036] For example, when the disc shear moves at a constant speed, the aforementioned disc shear jamming stroke information can be determined based on the time information from the disc shear jamming to its return to normal and the disc shear's operating speed information. Specifically, the aforementioned time information from the disc shear jamming to its return to normal can be determined based on the time information where the disc shear's torque information is greater than or equal to a preset torque threshold. Specifically, the disc shear jamming stroke information can be determined according to the following formula:

[0037] L _jam =T _maxtq ×V _stm (2)

[0038] Among them, L _jam For the disc shear resistance stroke, T _max tq For the duration during which the torque information of the disc shear is greater than or equal to a preset torque threshold, V _stm The speed of the disc shear is denoted as .

[0039] For example, in the case of variable speed operation of the disc shear, the aforementioned disc shear jamming stroke information can also be determined according to the following steps: obtaining the scan cycle information of the PLC (Programmable Logic Controller), the running speed information of the disc shear, the time information from the disc shear jamming to its return to normal state (i.e., jamming duration information), and the running mileage information of the disc shear; determining the running mileage information of the disc shear based on the scan cycle information and the running speed information; determining the number of jamming cycles based on the scan cycle information and the jamming duration information; and determining the disc shear jamming stroke based on the number of jamming cycles and the running mileage information.

[0040] Specifically, the mileage information of the aforementioned disc shear can be determined according to the following formula:

[0041] L _cycle =T _scan ×V _stm (3)

[0042] Among them, L _cycle For running mileage, T _scan For the scan period, V _stm This refers to the speed of the disc shear.

[0043] Specifically, the above-mentioned number of blocking cycles can be determined according to the following formula:

[0044]

[0045] Where, n _maxtq T is the number of blocking cycles. _maxtq For the duration of the jamming, T _scan This refers to the scan cycle. It should be noted that n represents the number of blocking cycles. _maxtq Integer

[0046]

[0047] Among them, L _jam For the disk shear stop stroke, n _maxtq L represents the number of blocking cycles. _cycle This refers to the operating mileage.

[0048] Step S120: If the disc shear jamming stroke information is greater than or equal to the disc shear blade circumference information, determine that the disc shear jamming type is a continuous jamming type and output an edge blockage alarm.

[0049] For example, if the disc shear's jamming stroke information is greater than or equal to the disc shear blade circumference information, thus determining that the disc shear's jamming type is a continuous jamming type, a jamming alarm can be output. This alarm can be a sound and light alarm that emits an alarm sound and flashes at a frequency of once every 0.25 seconds.

[0050] Alternatively, the disc shear jamming type can be determined as a continuous jamming type in the following manner: obtain the torque information, speed information, and unit speed information of the disc shear; if the torque information is greater than or equal to a preset torque threshold, obtain the torque information of the disc shear a second time after the disc shear has run continuously for one cycle; if the torque information is still greater than or equal to the preset torque threshold and the speed information of the disc shear is less than the unit speed information, then the disc shear jamming type is determined to be a continuous jamming type.

[0051] It should be noted that the torque information of the aforementioned disc shear may include: torque information on the drive side of the disc shear and / or torque information on the operating side of the disc shear. The speed information of the aforementioned disc shear may include: speed information on the drive side of the disc shear and / or speed information on the operating side of the disc shear. Specifically, the speed information of the disc shear can be determined based on the rotational speed measured by an encoder mounted on the bearing of the disc shear motor. The speed information on the drive side of the disc shear can be determined based on the rotational speed of the drive-side motor. The speed information of the operating side of the disc shear can be determined based on the rotational speed of the operating-side motor. The speed information of the aforementioned unit can be determined based on the strip steel transmission speed or the strip steel pulling speed. The aforementioned preset torque threshold can be determined based on the rated torque information of the motor.

[0052] Step S130: If the disc shear jamming stroke information is less than the disc shear blade circumference information, determine that the disc shear jamming type is intermittent jamming type, record the number of intermittent jammings of the disc shear and output a jamming reminder.

[0053] For example, if the disc shear's jamming stroke information is less than the disc shear blade circumference information, which indicates that the disc shear's jamming type is intermittent, the number of intermittent jamming events is recorded and a jamming warning is output. Specifically, the alarm can be an audible and visual alarm that emits an alarm sound and flashes at a frequency of once every 0.5 seconds.

[0054] It should be noted that the alarm frequency for edge blocking alerts is lower than that for edge blocking alarms.

[0055] For example, the number of times the disc shear jamming stroke information is less than the disc shear blade circumference information can be accumulated to record the number of times the disc shear intermittently jams.

[0056] Alternatively, the disc shear jamming type can be determined as intermittent jamming by acquiring the disc shear's torque information, disc shear speed information, and unit speed information. If the torque information is greater than or equal to a preset torque threshold, after the disc shear has run for one continuous cycle, the disc shear's torque information is acquired again. If the torque information decreases to below the preset torque threshold and / or the disc shear speed information is greater than or equal to the unit speed information (i.e., the torque information decreases while the speed information increases), then the disc shear jamming type is determined to be intermittent jamming. It should be noted that the unit speed information can be the linear velocity information of the unit's outlet section.

[0057] It should be noted that the torque and speed information of the disc shear can be determined based on the motor operating information, and the speed information of the above-mentioned unit can be determined based on the strip transmission speed or strip pulling speed, which will not be elaborated here.

[0058] The disc shear edge-clogging alarm control method proposed in this application includes: acquiring the disc shear blade circumference information and the disc shear jamming stroke information, wherein the disc shear jamming stroke information is the cumulative stroke information of the disc shear from jamming to returning to normal, and the cumulative stroke information is the circumferential rolling distance information; when the disc shear jamming stroke information is greater than or equal to the disc shear blade circumference information, the disc shear jamming type is determined to be continuous jamming type, and an edge-clogging alarm is output; when the disc shear jamming stroke information is less than the disc shear blade circumference information, the disc shear jamming type is determined to be intermittent jamming type, the number of intermittent jamming events is recorded, and an edge-clogging reminder is output. This application can accurately determine the disc shear jamming type using disc shear and production line data without installing additional hardware equipment, accurately output edge-clogging alarms or edge-clogging reminders based on the disc shear jamming type, and count the number of times the disc shear jams intermittently, which is beneficial for accurately controlling the intermittent jamming situation of the disc shear and providing data support for subsequent processing procedures.

[0059] In some feasible implementations, when the disc shear jamming type is intermittent jamming, the above method further includes: acquiring the cumulative number of times the disc shear experiences intermittent jamming; acquiring the disc shear's lifespan mileage information when the cumulative number of intermittent jammings is greater than a first preset threshold and less than or equal to a second preset threshold; outputting a blockage alarm when the lifespan mileage information is greater than a preset lifespan mileage threshold; and outputting a blockage alarm when the cumulative number of intermittent jammings is greater than the second preset threshold, wherein the first preset threshold is less than the second preset threshold.

[0060] For example, the first preset number of times threshold and the second preset number of times threshold can be determined based on the linear speed of the unit, the strip transmission speed, or the strip pulling speed. It should be noted that the first preset number of times threshold and the second preset number of times threshold are negatively correlated with the linear speed of the unit, the strip transmission speed, or the strip pulling speed; that is, the faster the linear speed of the unit, the strip transmission speed, or the strip pulling speed, the smaller the first preset number of times threshold and the second preset number of times threshold. Alternatively, the first preset number of times threshold and the second preset number of times threshold can also be determined based on the usage time, wear level, or lifespan mileage information of the disc shear. It should be noted that the first preset number of times threshold and the second preset number of times threshold are negatively correlated with the usage time, wear level, or lifespan mileage information of the disc shear; that is, the longer the usage time of the disc shear, the higher the wear level, or the greater the lifespan mileage information, the smaller the first preset number of times threshold and the second preset number of times threshold. Specifically, when the linear speed, strip transmission speed, or strip pulling speed of the unit is less than or equal to 30 m / min, the first preset number threshold can be 3 times, and the second preset number threshold can be 5 times.

[0061] For example, the aforementioned preset lifespan mileage threshold can be determined based on the material of the disc shear blade. Specifically, the value range of the aforementioned preset lifespan mileage threshold can be greater than or equal to 120km and less than or equal to 240km. Specifically, the aforementioned preset lifespan mileage threshold can be 150km.

[0062] For example, if the cumulative number of intermittent jamming events is less than or equal to 3, production continues. If the cumulative number of intermittent jamming events is greater than 3 but less than or equal to 5, and the lifespan of the disc shear is greater than or equal to 150 km, a blockage alarm is output. If the cumulative number of intermittent jamming events is greater than 3 but less than or equal to 5, and the lifespan of the disc shear is less than 150 km, production continues. If the cumulative number of intermittent jamming events is greater than 5, a blockage alarm is output.

[0063] It should be noted that because the stress and heat generated during the shearing process are concentrated on the small contact surface of the disc shear blade, the blade temperature increases, leading to accelerated softening and wear, which can easily cause chipping or burns. If the blade life mileage information exceeds a preset threshold, an additional blade replacement reminder can be output to prompt workers to replace the blade in a timely manner. Specifically, by adjusting the disc shear's rotating platform to a preset position, the disc shear blade can be replaced, while the life mileage information is automatically reset to zero.

[0064] Therefore, the above method can, in the event of intermittent jamming of the disc shear, comprehensively judge and control the production line to output a jamming alarm or stop production based on the cumulative number of times the disc shear has intermittently jammed and the disc shear's lifespan information, which is conducive to ensuring safe production and improving the efficiency of disc shear jamming abnormality handling.

[0065] In some feasible implementations, the above method further includes: acquiring scan cycle information, correction parameter information, and running time information of the disc shear from the programmable logic controller, wherein the correction parameter information is positively correlated with the strip thickness information; determining the running mileage information of the disc shear within the scan cycle based on the scan cycle information, correction parameter information, and speed information of the disc shear; determining the number of scan cycles based on the running time information and scan cycle information of the disc shear; and determining the lifespan mileage information based on the running mileage information and the number of scan cycles information.

[0066] It should be noted that the scan cycle information mentioned above refers to the scan cycle of the PLC (Programmable Logic Controller), which can be determined based on the PLC's hardware information.

[0067] For example, the above-mentioned correction parameter information can be determined based on the strip thickness information. Table 1 is a comparison table of correction parameter information and strip thickness information. As shown in Table 1, when the strip thickness is greater than 0.3 mm and less than or equal to 0.5 mm, the above-mentioned correction parameter can be 1 mm; when the strip thickness is greater than 0.5 mm and less than or equal to 0.8 mm, the above-mentioned correction parameter can be 1.1 mm; when the strip thickness is greater than 0.8 mm and less than or equal to 1.0 mm, the above-mentioned correction parameter can be 1.15 mm; when the strip thickness is greater than 1.0 mm and less than or equal to 1.5 mm, the above-mentioned correction parameter can be 1.2 mm; and when the strip thickness is greater than 1.5 mm and less than or equal to 2 mm, the above-mentioned correction parameter can be 1.3 mm.

[0068] 1 (0.3,0.5] 1 2 (0.5,0.8] 1.1 3 (0.8,1.0] 1.15 4 (1.0,1.5] 1.2 5 (1.5,2.0] 1.3

[0069] Table 1

[0070] It should be noted that the above runtime information for the disc shear refers to the total runtime of the disc shear.

[0071] Specifically, the above-mentioned mileage information can be equal to the product of the scanning cycle information, the speed information of the disc shear, and the correction parameter information, which can be calculated and determined according to the following formula:

[0072] L _cycle =T _scan ×V _stm ×F _thickness (6)

[0073] Among them, L _cycle For running mileage, T _scan For the scan period, V _stm F is the speed of the disc shear. _thickness To correct the parameters.

[0074] Specifically, the above-mentioned number of scanning cycles can be equal to the ratio of the operating time of the disc shear to the scanning cycle information, which can be calculated and determined according to the following formula:

[0075]

[0076] Where n is the number of scan cycles, T is the runtime, and T _scan is the scan period. It should be noted that n is an integer.

[0077] Specifically, the lifespan mileage information is the sum of the operating mileage information corresponding to the number of scan cycles, and can be calculated using the following formula:

[0078]

[0079] Among them, L _acc Lifetime mileage, n is the number of scan cycles, L _cycle This refers to the operating mileage.

[0080] Therefore, the above method can determine the lifespan information based on scanning cycle information, correction parameter information, and the running time and speed information of the disc shear. This allows for precise determination of whether to output a blocking alarm when the cumulative number of intermittent jamming events exceeds a first preset threshold. This alerts the user that the disc shear's lifespan has reached the preset threshold, increasing the risk of blocking. It assists the user in determining whether to perform a shutdown operation and replace the disc shear blade, thereby ensuring safe production, scientifically judging blade replacement time, and reducing blade replacement costs.

[0081] In some feasible implementations, the above method further includes: receiving a unit speed-up command or a shutdown command within a preset time when a blockage alarm is output; controlling the unit to speed up when a unit speed-up command is received within the preset time; and controlling the unit to speed down until shutdown when no unit speed-up command is received within the preset time or when a shutdown command is received.

[0082] For example, the preset time can be defined by the user according to the actual situation of the production line. Specifically, the preset time can be 1 second.

[0083] For example, when the disc shear jamming type is determined to be continuous jamming; or when the disc shear jamming type is intermittent jamming, the number of intermittent jamming occurrences is greater than a first preset threshold and less than or equal to a second preset threshold, and the disc shear's lifespan mileage information is greater than or equal to the preset lifespan mileage threshold; or when the disc shear jamming type is intermittent jamming, and the number of intermittent jamming occurrences is greater than the second preset threshold, i.e., when an edge blockage alarm is output, a user-inputted speed-up command or shutdown command can be received. If a user-inputted speed-up command is received within 1 second, the unit is controlled to speed up. If a user-inputted shutdown command is received within 1 second, or if no speed-up command or shutdown command is received within a preset time, the unit is controlled to slow down until shutdown.

[0084] Therefore, the above method, when outputting a blockage alarm, can automatically control the unit to speed up or stop based on the received unit speed-up command or stop command within a preset time to eliminate the blockage abnormality. If no unit speed-up command is received within the preset time or a stop command is received, the unit will automatically control the unit to speed down until it stops to ensure safe production.

[0085] In some feasible implementations, the above method further includes: determining unit crawling stage information based on unit speed information, wherein the unit crawling stage information includes first stage information, second stage information and third stage information, the unit speed information corresponding to the first stage information is less than the unit speed information corresponding to the second stage information, the unit speed information corresponding to the second stage information is less than the unit speed information corresponding to the third stage information, the first preset number threshold corresponding to the second stage is less than the first preset number threshold corresponding to the first stage, and the second preset number corresponding to the second stage is less than the second preset number corresponding to the first stage.

[0086] For example, when the unit speed information is less than or equal to a first preset unit speed threshold, the aforementioned unit crawling stage can be determined as the first stage. When the unit speed information is greater than the first preset unit speed threshold and less than or equal to a second preset unit speed threshold, the aforementioned unit crawling stage can be determined as the second stage. When the unit speed information is greater than the first preset unit speed threshold and less than or equal to the second preset unit speed threshold, the aforementioned unit crawling stage can be determined as the second stage. When the unit speed information is greater than the second preset unit speed threshold, the aforementioned unit crawling stage is determined as the third stage. The aforementioned first preset unit speed threshold and second preset unit speed threshold can be determined based on actual production experience. Specifically, the aforementioned first preset unit speed threshold can be 30 m / min, and the second preset unit speed threshold can be 60 m / min.

[0087] For example, when the unit crawling phase is determined to be the first phase, that is, when the unit speed information is less than or equal to 30m / min, the first preset number of times can be 3 times, and the second preset number of times can be 5 times.

[0088] Specifically, if the unit's creeping phase is determined to be the first stage (i.e., the unit speed is less than or equal to 30 m / min) and the cumulative number of intermittent jamming events is less than or equal to 3, then production continues. If the cumulative number of intermittent jamming events is greater than 3 but less than or equal to 5, and the lifespan of the disc shear is greater than or equal to 150 km, then a blockage alarm is output. If the cumulative number of intermittent jamming events is greater than 3 but less than or equal to 5, and the lifespan of the disc shear is less than 150 km, then production continues. If the cumulative number of intermittent jamming events is greater than 5, then a blockage alarm is output.

[0089] For example, when the unit crawling phase is determined to be the first phase, that is, when the unit speed information is less than or equal to 60m / min, the first preset number of times can be 2 times, and the second preset number of times can be 4 times.

[0090] Specifically, if the unit's creeping phase is determined to be the first stage (i.e., the unit speed is less than or equal to 60 m / min) and the cumulative number of intermittent jamming events is less than or equal to 2, production continues. If the cumulative number of intermittent jamming events is greater than 2 but less than or equal to 4, and the disc shear's service life is greater than or equal to 150 km, a blockage alarm is output. If the cumulative number of intermittent jamming events is greater than 4 but less than or equal to 5, and the disc shear's service life is less than 150 km, production continues. If the cumulative number of intermittent jamming events is greater than 4, a blockage alarm is output.

[0091] Therefore, the above method can determine the creep stage information of the unit based on the unit speed information when the disc shear jamming type is determined to be intermittent jamming type. Then, based on the first preset number threshold and the second preset number threshold corresponding to the unit creep stage information, the adaptability of the method for edge blocking alarm under different creeping stages of the unit is improved, the edge blocking alarm accuracy is improved, which is conducive to improving the safety of the production process and improving the handling efficiency of disc shear edge blocking abnormalities.

[0092] In some feasible implementations, the above method further includes: when an edge blockage alarm is output and the unit creep stage information is in the first stage, controlling the unit speed to increase to the unit speed corresponding to the second stage information to eliminate the edge blockage abnormality; when an edge blockage alarm is output and the unit creep stage information is in the second stage, controlling the unit speed to increase to the unit speed corresponding to the third stage information to eliminate the edge blockage abnormality; when an edge blockage alarm is output and the unit creep stage information is in the third stage, controlling the unit speed to decrease to eliminate the edge blockage abnormality.

[0093] It should be noted that the operating speed of the disc shear is positively correlated with the unit speed; that is, the faster the unit speed, the faster the disc shear operates, and vice versa. When the unit speed is low, i.e., during the first or second crawling stage, the disc shear operates at a low speed and has poor shearing performance. In this stage, the unit speed can be increased to create a shearing advantage, which helps the disc shear overcome edge blockage.

[0094] For example, when an edge blockage alarm is output and the unit is in the first stage of the creep phase, i.e., the unit speed information is less than or equal to 30 m / min, if the disc shear jamming type is determined to be continuous jamming type, or if the disc shear jamming type is determined to be intermittent jamming type, and the cumulative number of intermittent jamming events is greater than 3 times and less than or equal to 5 times, and the disc shear's lifespan is greater than or equal to 150 km, or if the cumulative number of intermittent jamming events is greater than 5 times, the unit speed can be controlled to less than or equal to 60 m / min to eliminate the edge blockage abnormality.

[0095] For example, when an edge-blocking alarm is output and the unit is in the second stage of the creep phase (i.e., the unit speed is less than or equal to 60 m / min), if the disc shear jamming type is determined to be continuous jamming, or if the disc shear jamming type is determined to be intermittent jamming, and the cumulative number of intermittent jamming events is greater than 2 and less than or equal to 4, and the disc shear's service life is greater than or equal to 150 km, or if the cumulative number of intermittent jamming events is greater than 3, the unit speed can be controlled to increase to greater than 60 m / min. Specifically, based on the disc shear's operating condition information, the unit speed can be controlled to increase to greater than 60 m / min and less than or equal to 120 mm / min to eliminate edge-blocking abnormalities.

[0096] It should be noted that when the unit speed is high, that is, when the unit is in the third stage of the creep stage, the disc shear is in the high-speed operation stage. At this stage, the shearing advantage formed by the disc shear's accelerated operation has been saturated. Furthermore, due to the high operating speed of the disc shear, it is easy to cause the shear blade to overheat and fatigue. Therefore, it is necessary to reduce the unit speed to avoid aggravating the jamming situation.

[0097] For example, when an edge blockage alarm is output and the unit is in the third stage of the creep phase, that is, when the unit speed information is greater than 60m / min, for example, when the unit speed is 120m / min, the unit speed is controlled to decrease until the edge blockage alarm is no longer output.

[0098] Therefore, the above method can automatically control the speed of the unit to eliminate the edge blockage when the edge blockage alarm is output and the unit is in the first or second stage of the creep stage; when the unit is in the third stage of the creep stage, it can automatically control the speed of the unit to decrease until the edge blockage is eliminated. This is beneficial for overcoming edge blockage without stopping the machine, protecting the disc shear, ensuring safe production, and ensuring orderly production, thereby improving production efficiency.

[0099] In some feasible implementations, when the crawling stage information is third stage information, the above method further includes: acquiring the duration information of continuous jamming; outputting an edge jamming alarm when the duration information is greater than a preset duration threshold; and / or acquiring the speed information of the disc shears, outputting an edge jamming alarm when the speed information is less than a preset speed threshold, wherein the speed information includes: speed information on the transmission side and / or speed information on the operation side.

[0100] For example, the duration information of the continuous jamming can be determined based on the duration information of the edge blocking alarm.

[0101] For example, the aforementioned preset duration threshold can be determined based on the usage time, wear level, or lifespan of the disc shears. Specifically, the preset duration threshold is negatively correlated with the usage time, wear level, or lifespan of the disc shears; that is, the greater the usage time, wear level, or lifespan of the disc shears, the smaller the preset duration threshold. Specifically, the aforementioned preset duration threshold can be 1 second.

[0102] Specifically, when the crawling phase information is in the third stage (i.e., the unit speed is greater than 60 m / min) and the duration is greater than 1 second, a blocking alarm is output. If the duration is less than or equal to 1 second, no additional alarm is triggered. In some feasible implementations, if the lifespan of the disc shear is determined to be greater than a preset lifespan threshold when the duration is less than or equal to 1 second, a blocking alarm is output; otherwise, no additional alarm is triggered.

[0103] For example, the aforementioned preset speed threshold can be determined based on the enterprise's actual edge-blocking alarm accuracy requirements or based on the operating time, wear level, or lifespan mileage of the disc shear. Specifically, the preset speed threshold is negatively correlated with the enterprise's actual edge-blocking alarm accuracy requirements; that is, the higher the enterprise's actual edge-blocking alarm accuracy requirements, the smaller the preset speed threshold. The preset speed threshold is also negatively correlated with the disc shear's operating time, wear level, or lifespan mileage; that is, the greater the operating time, wear level, or lifespan mileage of the disc shear, the smaller the preset speed threshold can be. Specifically, the aforementioned preset speed threshold can be 0 m / min.

[0104] Specifically, if the speed information of the disc shear is determined to be less than 0, that is, if the speed on the transmission side of the disc shear and / or the speed on the operation side of the disc shear is less than 0, then a jamming alarm will be output.

[0105] In some feasible methods, when the crawling phase information is the third stage information and the edge blocking alarm is output (i.e., the duration information is greater than the preset duration threshold, or the duration information is less than or equal to the preset duration threshold, and the life mileage information of the disc shear is greater than the preset life mileage threshold, or the speed information of the disc shear is less than the preset speed threshold), the unit speed can be controlled to gradually decrease in order to eliminate the edge blocking abnormality.

[0106] Specifically, when the crawling phase information is in the third stage (i.e., the unit speed is greater than 60 m / min) and a blockage alarm is output (i.e., the duration is greater than 1 second, or less than or equal to 1 second), and the disc shear's lifespan is greater than 150 km, or the disc shear's speed is less than 0, determine if the unit speed is greater than 120 m / min. If the unit speed is greater than 120 m / min, control the unit speed to reduce it to less than 120 m / min. If the unit speed is greater than or equal to 60 m / min but less than 120 m / min, control the unit speed to reduce it to less than 60 m / min until the blockage risk is eliminated.

[0107] Therefore, the above method can achieve the following: when the creeping stage information of the unit is determined to be the third stage information, the edge blockage alarm can be output based on the duration of continuous jamming and the speed information of the disc shear. This improves the accuracy of the edge blockage alarm when the unit speed is relatively high, further enhances production safety when the disc shear is running at high speed, and helps protect the production equipment.
