Abstract
Description
Technical Field
[0001] This application relates to the technical field of bundling and packaging, and in particular to a control method and control system for a packaging machine. Background Technology
[0002] Cardboard baling machines are commonly used equipment in the packaging industry to bundle stacked cardboard into bundles. They are widely used in printing, logistics and manufacturing fields. They can bind loose or stacked cardboard and other materials into a neat whole, making it convenient for subsequent storage and transportation.
[0003] However, existing packaging machines typically transport stacked cardboard directly to the packaging station before bundling. This often results in uneven edges on the stacked cardboard, leading to irregular bundle shapes. This not only occupies more storage and transport space but also increases the risk of loose or detached bundles, affecting packaging quality. Furthermore, traditional swing arms use circular motion to guide the bundling rope around the cardboard. This motion requires significant space, easily interfering with the machine frame or cardboard, and the high-speed rotation stirs up dust, contaminating the cardboard surface. Overall, packaging efficiency is low, and rope jamming is more likely, impacting stable equipment operation.
[0004] Therefore, there is an urgent need to provide a control method and system for a baling machine to improve the overall efficiency of baling operations and ensure the uniformity of the bundled materials. Summary of the Invention
[0005] To address the aforementioned problems, this application provides a control method and control system for a packaging machine.
[0006] A method for controlling a packing machine includes the following steps: Step S1: Obtain the alignment start command, control the three-sided alignment mechanism to perform the alignment action, and complete the three-sided alignment of the material to be bundled; Step S2: After the alignment is completed, a release command is obtained to control the three-sided alignment mechanism to release the material to be bundled and transport the aligned material to the working position of the clamping and pushing mechanism. Step S3: Obtain the push start command, control the clamping push mechanism to clamp both sides of the material to be bundled, and push the material to be bundled to the bundling station; Step S4: Obtain the bundling start command, control the vertical rope feeding bundling mechanism to complete the bundling of the material to be bundled in a vertical rope feeding manner, and then the bundled material leaves the bundling station.
[0007] By adopting the above technical solution, the control method of this application, through obtaining the aligning start command, controls the three-sided aligning mechanism to perform the aligning action, which can accurately complete the three-sided aligning of the material to be bundled, resulting in a more uniform appearance compared to traditional two-sided aligning. Secondly, by obtaining the release command, the three-sided aligning mechanism releases the material and transports it to the clamping and pushing mechanism, ensuring smooth material flow. Further, by obtaining the pushing start command, the clamping and pushing mechanism clamps both sides of the material and pushes it to the bundling station, preventing the material from scattering during the pushing process. Finally, by obtaining the bundling command, the vertical rope feeding bundling mechanism uses a vertical rope feeding method for bundling. Compared to the traditional circular swing arm rope feeding, it requires less movement space, does not interfere with the frame or material, and is less likely to stir up dust and contaminate the material, reducing the probability of rope feeding jamming failures. This effectively improves the overall efficiency of the packaging operation, ensures bundling quality, and makes the equipment operation more stable. The various steps of the entire control method work closely together to achieve efficient and stable packaging operations and are applicable to materials of different sizes to be bundled.
[0008] Furthermore, step S1 specifically includes the following steps: Step S11: Obtain the alignment start command, control the front baffles on the left and right alignment plates of the three-sided alignment mechanism to extend to the reference position respectively to form the front alignment plate, and transport the material to be bundled to contact the front alignment plate. Step S12: Drive the left and right aligning plates to move towards the center, and collect the contact pressure between the left and right aligning plates and the material to be bundled in real time. Step S13: When any contact pressure reaches the preset threshold, the corresponding side alignment plate stops moving until both sides reach the threshold, thus completing the three-sided alignment.
[0009] By adopting the above technical solution, the control system receives the alignment start command and uses electrical signals to control the front baffles on the left and right alignment plates to extend to the reference position to form the front alignment plate, achieving the initial positioning of the material to be bundled. When driving the left and right alignment plates to move towards the center, the contact pressure with the material is collected in real time through electrical signals. When the pressure reaches a preset threshold, the electrical signal controls the corresponding side alignment plate to stop moving, ensuring that the pressure on the material is appropriate and uniform. This control method can precisely control the alignment action, avoid the instability of traditional mechanical control, improve alignment accuracy and consistency, effectively solve the problem that traditional baling machines can only align from two sides, provide a stable foundation for subsequent material bundling processes, and enhance the overall performance and reliability of the baling machine.
[0010] Furthermore, step S2 specifically includes the following steps: Step S21: Obtain the recovery and release command, control the left and right aligning plates of the three-sided aligning mechanism to return to their original positions, and control the front baffles on the corresponding sides to retract, releasing the materials to be bundled that have been aligned. Step S22: After the bundled material is released, control the first conveying mechanism to transport it along the conveying direction to the working position of the clamping and pushing mechanism.
[0011] By adopting the above technical solution, after the three-sided aligning mechanism completes aligning, the control system receives a release command and controls the left and right aligning plates to return to their original positions via electrical signals, while the front baffle retracts, accurately releasing the aligned material to be bundled. Simultaneously, the first conveying mechanism is controlled to transport the material accurately to the working position of the clamping and pushing mechanism along the conveying direction. This method ensures the orderly connection between material release and transportation, improves the automation and accuracy of the baling machine control, and effectively enhances the overall efficiency and stability of the baling operation.
[0012] Furthermore, step S3 specifically includes the following steps: Step S31: Obtain the push start command and control the left and right slide rails of the clamping push mechanism to move closer to each other, so that the first moving clamp on the left slide rail and the second moving clamp on the right slide rail clamp the two sides of the material to be bundled with a preset fixed clamping force. Step S32: While maintaining the clamped state, drive the first moving clamp and the second moving clamp to push the material to be bundled to the bundling station; Step S33: After the bundled material arrives at the bundling station, release the clamping force, and the first and second moving clamps slide back to their original positions.
[0013] By adopting the above technical solution, after receiving the push start command, the control system uses electrical signals to control the left and right slide rails of the clamping push mechanism to drive the moving clamping plates closer to each other, clamping the two sides of the material with a preset fixed clamping force. This can adapt to materials of different widths to be bundled, while maintaining a stable clamping force to avoid over-clamping and damaging the material, or under-clamping causing the material to shift and scatter during the push process. Maintaining the clamped state during the push process ensures that the material maintains its neat shape after being aligned, preventing the material from scattering during the transfer. After the material arrives at its destination, the clamping is released and the clamping plates return to their original positions, preparing for the next push operation. This control method makes the entire push process precise and the actions smooth, effectively ensuring the stable flow of materials from the alignment station to the bundling station, maintaining the neatness of the aligned materials, and providing a good foundation for subsequent bundling processes.
[0014] Furthermore, step S4 specifically includes the following steps: Step S41: Obtain the strapping start command, control the upper pressure plate to press down, and tighten the material to be strapped; Step S42: Control the vertical swing arm of the vertical rope feeding and binding mechanism to swing vertically downward from the standby position, and vertically feed the binding rope to the material to be bound. Step S43: Control the second conveying mechanism to move the material to be bundled horizontally, and at the same time control the vertical swing arm to lift upward, so that the binding rope naturally wraps around the material to be bundled during its movement. Step S44: Control the vertical swing arm to swing downwards again to lock the binding rope to form a complete loop; Step S45: Control the strapping machine head to tighten the strapping rope and perform heat fusion connection, cut off the excess rope tail, and complete the strapping. The second conveying mechanism transports the strapped material away from the strapping station.
[0015] By adopting the above technical solution, after the material to be bundled arrives at the bundling station, a bundling start command is received. The control system controls the upper pressure plate to press down and fix the material to be bundled, preventing the material from shifting and loosening during the bundling process and ensuring accurate bundling position. Then, the control system controls the vertical swing arm to swing vertically downward to feed the rope, replacing the traditional circular swing arm's movement trajectory. This requires less movement space and avoids collisions or interference with the frame or material. At the same time, the low-speed vertical swing reduces air disturbance and prevents dust from contaminating the material surface. In conjunction with the second conveying mechanism, the material is moved horizontally to complete the bundling rope wrapping. Simultaneously, the vertical swing arm presses down a second time to lock the bundling rope. Finally, the bundling head completes the tightening and heat-melting cutting. The control method of this application achieves efficient and precise electrical control. The entire rope feeding and bundling process is smooth and continuous, significantly reducing the probability of rope feeding jams and other malfunctions, ensuring stable and continuous bundling operations, and improving packaging efficiency and quality.
[0016] Furthermore, in step S32, while the clamping and pushing mechanism clamps the left and right sides of the material to be bundled, the first conveying mechanism located at the bottom of the material to be bundled and the third conveying mechanism located at the top of the material are controlled to move synchronously to form a four-sided clamping state of the material to be bundled and push the material to the bundling station.
[0017] By adopting the above technical solution, in step S32, when the clamping and pushing mechanism clamps the left and right sides of the material to be bundled, the control system precisely controls the first conveying mechanism at the bottom of the material and the third conveying mechanism at the top to move synchronously. This control method enables the three to work together to form a stable four-sided clamping state for the material to be bundled, effectively avoiding problems such as displacement and tipping of the material during the pushing process, ensuring that the material can be pushed smoothly and accurately to the bundling station, and improving the stability and efficiency of the packaging process.
[0018] This application also provides a control system for a baling machine, used to implement the control method for a baling machine described above, including: The alignment control module is used to obtain the alignment start command and control the three-sided alignment mechanism to align the material to be bundled on three sides, or to obtain the release command and control the three-sided alignment mechanism to release the material. The conveying control module is used to control the first conveying mechanism to transport materials to the working position of the clamping and pushing mechanism, or to control the second conveying mechanism to transport materials away from the binding station. The clamping control module is used to acquire the push start command and control the clamping push mechanism to clamp the material on both sides, and push the material to the bundling station; The bundling control module is used to obtain bundling start commands and control the vertical rope feeding bundling mechanism to complete the material bundling in a vertical rope feeding manner.
[0019] By adopting the above technical solutions, the control system of the baling machine of this application can effectively realize the above control methods. The alignment control module can accurately respond to commands, complete the three-sided alignment and release of materials, and make up for the shortcomings of traditional two-sided alignment. The conveying control module can orderly schedule the first conveying mechanism and the second conveying mechanism to ensure smooth material flow between each workstation, control the release of materials and transport them to the designated working position. The clamping control module receives the push start command and can accurately control the clamping and pushing action to maintain the neat shape of the material after alignment. The strapping control module receives the strapping start command and completes the strapping of materials in a vertical feeding manner, saving space and preventing contamination of materials, thus comprehensively improving the working efficiency and applicability of the baling machine. The various functional modules of the control system of this application cooperate with each other to realize the automated and precise control of the entire baling process, effectively improving the efficiency of baling operations and the quality of strapping.
[0020] Furthermore, the alignment control module includes a front baffle control unit, left and right alignment control units, and a pressure detection unit.
[0021] By adopting the above technical solution, the front baffle control unit can accurately control the front baffle to extend to the reference position to form the front alignment surface according to the alignment start command, thus completing the front positioning of the material; the left and right alignment control units can drive the left and right alignment plates to move synchronously towards the middle to complete the alignment operation; the pressure detection unit can collect the contact pressure between the alignment plates and the material in real time, and when the pressure reaches the preset threshold, it can send a signal to stop the corresponding side alignment plate from moving, ensuring that the alignment force is appropriate and uniform, realizing precise and stable three-sided alignment control, and effectively improving the accuracy and automation of the alignment process.
[0022] Furthermore, the clamping control module includes a clamping control unit and a push drive unit.
[0023] By adopting the above technical solution, the clamping control unit can accurately control the left and right moving clamps to move closer to each other according to the push start command, clamping the two sides of the material to be bundled with a preset fixed clamping force, adapting to materials of different widths, while ensuring stable clamping force, avoiding damage to the material or material displacement due to insufficient clamping; the push drive unit can drive the clamps to move the material stably to the bundling station while the material is in a clamped state, and control the clamps to release the clamp and return to the original position after reaching the position, ensuring that the push process is accurate and smooth, maintaining the neat shape of the material after it is aligned, and realizing stable automated control of the push process.
[0024] Furthermore, the strapping control module includes a pressing control unit, a vertical rope feeding control unit, and a strapping head control unit.
[0025] By adopting the above technical solutions, the pressing control unit can accurately control the upper pressure plate to press down and fix the material to be bundled before the bundling operation begins, avoiding material displacement during the bundling process; the vertical rope feeding control unit can control the vertical swing arm to complete the rope feeding operation according to the trajectory of vertical downward rope feeding and secondary downward pressing and locking, replacing the traditional circular swing arm movement, reducing the required movement space, avoiding interference with the frame or materials, and reducing the probability of rope feeding jamming failure; the bundling head control unit can accurately control the bundling head to complete the work of tightening the bundling rope, heat fusion connection and cutting off the excess rope tail after the bundling rope is wrapped, ensuring that the bundling joint is firm and neat, and finally successfully completing the entire bundling process, improving the stability and bundling quality of the bundling operation.
[0026] In summary, this application includes at least the following beneficial technical effects: (1) This application uses three-sided alignment control, which makes the material alignment more regular compared to the traditional two-sided alignment. The alignment force is precisely controlled by pressure detection, which can adapt to materials of different sizes, improve the alignment accuracy and stability, and lay a good foundation for subsequent processes. (2) This application uses a clamping and pushing mechanism in conjunction with an upper and lower conveying mechanism to form a multi-faceted clamping and pushing mechanism, which effectively avoids the material from being scattered and shifted during the pushing process, maintains the neat shape of the material after it is aligned, and ensures that the material is stably transferred to the bundling station. (3) This application adopts a vertical rope feeding and bundling control method. Compared with the traditional circular swing arm rope feeding, it requires less movement space, is less likely to interfere with the frame or materials, and reduces dust rising, reducing the probability of rope feeding jamming failure, effectively improving the overall efficiency and bundling quality of the packaging operation, and ensuring stable operation of the equipment.

[0029] The following combination Figure 1-8 The technical solutions in Embodiments 1-2 of the present invention will be described in detail.
[0030] Example 1 See Figure 1 Embodiment 1 of this application provides a control method for a packaging machine, comprising the following steps: Step S1: Obtain the alignment start command, control the three-sided alignment mechanism to perform the alignment action, and complete the three-sided alignment of the material to be bundled; Understandable, please refer to Figure 6 The three-sided aligning mechanism includes a left aligning plate 111, a right aligning plate 112, and a second front baffle 122 respectively installed on the left aligning plate 111 and the right aligning plate 112. The material to be bundled is cardboard or similar board-shaped material with a width ranging from 15cm to 2m. The initial distance between the left aligning plate 111 and the right aligning plate 112 is 2.1m to 2.5m.
[0031] Specifically, step S1 includes the following steps: Step S11: Obtain the alignment start command, control the front baffles on the left and right alignment plates of the three-sided alignment mechanism to extend to the reference position respectively to form the front alignment plate, and transport the material to be bundled to contact the front alignment plate. Step S12: Drive the left aligning plate 111 and the right aligning plate 112 to move towards the center, and collect the contact pressure between the left aligning plate 111 and the right aligning plate 112 and the material in real time.
[0032] As a preferred embodiment, the moving speed of the left aligning plate 111 and the right aligning plate 112 adopts segmented control of "fast approach, slow contact": first, it moves at a speed of 50 mm / s to a distance of 10 mm from the material, and then slowly contacts it at a speed of 10 mm / s to prevent the material from tilting due to impact.
[0033] Step S13: When any contact pressure reaches the preset threshold, the corresponding side alignment plate stops moving until both sides reach the threshold, thus completing the three-sided alignment.
[0034] Understandably, the preset threshold can be flexibly set according to the material and thickness. For example, it can be set to 0.2MPa to 0.4MPa for corrugated cardboard and 0.4MPa to 0.6MPa for rigid plastic or wood boards. This can accommodate materials of different widths and rigidities and avoid excessive compression that could damage the materials.
[0035] Furthermore, in this embodiment, based on the actual travel distance of the left aligning plate 111 and the right aligning plate 112 from their initial positions to their contact with the material and their stop in steps S12-S13, the width data of the material to be bundled is calculated, and the width data is transmitted to the clamping push mechanism and the vertical rope feeding and bundling mechanism to execute the next step.
[0036] Step S2: After the alignment is completed, a release command is obtained to control the three-sided alignment mechanism to release the material to be bundled and transport the aligned material to the working position of the clamping and pushing mechanism. Specifically, step S2 includes the following steps: Step S21: Obtain the recovery release command, control the left alignment plate 111 and the right alignment plate 112 of the three-sided alignment mechanism to return to their original positions, and control the front baffle on the corresponding side to retract, releasing the material that has been aligned.
[0037] Step S22: After the material is released, control the first conveying mechanism 21 to transport it along the conveying direction to the working position of the clamping and pushing mechanism.
[0038] In some embodiments, the first conveying mechanism is a roller conveying mechanism with an adjustable conveying speed, typically set to 0.3m / s to 0.5m / s. The roller surface of the roller conveying mechanism is covered with a rubber layer to increase friction with the material and prevent slippage.
[0039] Step S3: Obtain the push start command, control the clamping push mechanism to clamp both sides of the material to be bundled, and push the material to be bundled to the bundling station.
[0040] Understandably, the clamping and pushing mechanism includes a symmetrically arranged left slide rail 311 and right slide rail 312, a first movable clamping plate 313 mounted on the left slide rail 311, a second movable clamping plate 314 mounted on the right slide rail 312, a clamping driver for driving the left slide rail 311 and right slide rail 312 closer to or further apart, and a pushing driver for driving the first movable clamping plate 313 and the second movable clamping plate 314 to slide along the slide rails. The initial distance between the left slide rail 311 and right slide rail 312 is 2.1m to 2.5m, and the sliding stroke of the first movable clamping plate 313 and the second movable clamping plate 314 is 1m to 2m.
[0041] Specifically, step S3 includes the following steps: Step S31: Obtain the push start command and control the left slide rail 311 and right slide rail 312 of the clamping push mechanism to move closer to each other, so that the first moving clamping plate 313 on the left slide rail 311 and the second moving clamping plate 314 on the right slide rail 312 clamp the two sides of the material to be bundled with a preset fixed clamping force. Step S32: While maintaining the clamped state, drive the first moving clamp 313 and the second moving clamp 314 to push the material to be bundled to the bundling station; Furthermore, in this embodiment, while clamping the left and right sides of the material, the first conveying mechanism 21 located at the bottom of the material and the third conveying mechanism 23 located at the top of the material are controlled to move synchronously to form a four-sided clamping state for the material. The third conveying mechanism 23 consists of multiple conveying pulleys arranged along the conveying direction.
[0042] As an optional implementation, the clamping and pushing mechanism receives the width data from the three-sided aligning mechanism. Based on this width data, when the width of the material to be bundled is greater than 40cm, the clamping and pushing mechanism controls the pushing speed to be 0.3m / s to 0.6m / s; when the width of the material to be bundled is ≤40cm, the clamping and pushing mechanism automatically reduces the pushing speed to 0.1m / s to 0.2m / s, while maintaining the clamping force unchanged, to prevent narrow materials from tipping over due to inertia during the pushing process.
[0043] Step S33: After the bundled material arrives at the bundling station, release the clamping force, and the first moving clamp 313 and the second moving clamp 314 slide back to their original positions.
[0044] Step S4: Obtain the bundling start command, control the vertical rope feeding bundling mechanism to complete the bundling of the material to be bundled in a vertical rope feeding manner, and then the bundled material leaves the bundling station.
[0045] Understandably, see Figure 6-7 The vertical rope feeding and binding mechanism includes a vertical swing arm 421 and a swing arm drive motor 422. One end of the vertical swing arm 421 is hinged to the side of the frame, and the swing arm drive motor 422 drives the vertical swing arm 421 to swing from 0° to 180° in the vertical plane.
[0046] Step S4 specifically includes the following steps: Step S41: Obtain the bundling start command, control the upper pressure plate 411 to press down, and tighten the material to be bundled; Understandably, the vertical rope feeding and binding mechanism controls the downward pressure of the upper pressure plate 411 to adaptively adjust according to the material width data calculated in step S1: when the material width is greater than 40cm, the pressure is 0.3MPa to 0.5MPa, and when the material width is less than or equal to 40cm, the pressure is 0.05MPa to 0.1MPa, effectively preventing narrow materials from being crushed or tipped over.
[0047] Step S42: Control the vertical swing arm 421 of the vertical rope feeding and binding mechanism to swing vertically downward from the standby position, and vertically feed the binding rope to the material to be bound. The swing speed range of the vertical swing arm 421 is 0.1m / s to 0.5m / s.
[0048] Step S43: Control the second conveying mechanism 22 to drive the material to be bundled to move horizontally, and at the same time control the vertical swing arm 421 to lift upward, so that the binding rope naturally wraps around the material to be bundled during its movement. In this embodiment, the second conveying mechanism 22 is a conveyor belt conveying mechanism with a moving speed range of 0.2m / s to 0.6m / s.
[0049] Step S44: Control the vertical swing arm 421 to swing downwards again, locking the binding rope to form a complete loop; Step S45: Control the strapping machine head to tighten the strapping rope and perform heat fusion connection, cut off the excess rope tail, and complete the strapping. The second conveying mechanism 22 transports the strapped material away from the strapping station.
[0050] Example 2 See Figure 2 Embodiment 2 of this application provides a control system for a packaging machine that implements the method described in Embodiment 1, comprising: Alignment control module 1 is used to obtain the alignment start command and control the three-sided alignment mechanism to align the material to be bundled on three sides, or to obtain the release command and control the three-sided alignment mechanism to release the material. The conveying control module 2 is used to control the first conveying mechanism to transport materials to the working position of the clamping and pushing mechanism, or to control the second conveying mechanism to transport materials away from the binding station. The clamping control module 3 is used to obtain the push start command and control the clamping push mechanism to clamp the two sides of the material and push the material to the bundling station; The bundling control module 4 is used to obtain the bundling start command and control the vertical rope feeding bundling mechanism to complete the material bundling in a vertical rope feeding manner.
[0051] See Figure 3 The alignment control module 1 includes a front baffle control unit 11, left and right alignment control units 12, and a pressure detection unit 13. The front baffle control unit 11 controls the extension or retraction of the front baffles on the left and right alignment plates 111 and 112. The left and right alignment control units 12 drive the left and right alignment plates 111 and 112 to move towards the center or return to their original positions. The pressure detection unit 13 collects the contact pressure between the left and right alignment plates 111 and 112 and the material in real time, and sends a stop signal to the left and right alignment control units 12 when a preset threshold is reached. When an alignment start command is received, the module controls the front baffles to extend and the left and right alignment plates 111 and 112 to move towards the center to complete alignment. When a release command is received, the module controls the left and right alignment plates 111 and 112 to retract and the front baffles to retract, releasing the material.
[0052] Furthermore, the alignment control module 1 also includes a width detection unit, which is used to calculate the material width data based on the moving stroke of the left alignment plate 111 and the right alignment plate 112, and send the width data to the clamping control module 3 and the bundling control module 4.
[0053] See Figure 4The clamping control module 3 includes a clamping control unit 31 and a push drive unit 32. The clamping control unit 31 controls the left slide rail 311 and the right slide rail 312 to move closer or further apart, so that the first moving clamping plate 313 and the second moving clamping plate 314 clamp the material on both sides with a preset clamping force. The push drive unit 32 drives the first moving clamping plate 313 and the second moving clamping plate 314 to push the material to the binding station while maintaining the clamping state, and drives the material to slide back to its original position after it arrives.
[0054] The clamping control module 3 is also used to receive the width data sent by the alignment control module 1 and adjust the pushing speed according to the width data: when the material width is greater than 40cm, the pushing speed is 0.3m / s to 0.6m / s, and when the material width is ≤40cm, the pushing speed is 0.1m / s to 0.2m / s.
[0055] See Figure 5 The strapping control module 4 includes a pressing control unit 41, a vertical rope feeding control unit 42, and a strapping head control unit 43. The pressing control unit 41 controls the upper pressure plate 411 to press down; the vertical rope feeding control unit 42 controls the vertical swing arm 421 to swing vertically downward from its standby position to deliver the strapping rope below the material, controls the vertical swing arm 421 to lift upward to coordinate with the material movement so that the strapping rope naturally wraps around, and controls the vertical swing arm 421 to swing downward again to lock the strapping rope into a complete loop; the strapping head control unit 43 controls the strapping head to perform tightening, heat-sealing, and cutting of the strapping rope.
[0056] The bundling control module 4 is also used to receive the width data sent by the alignment control module 1 and adjust the pressure of the upper pressure plate according to the width data: when the material width is greater than 40cm, the pressure is 0.3MPa~0.5MPa, and when the material width is ≤40cm, the pressure is 0.05MPa~0.1MPa.
[0057] Understandably, the alignment control module 1, conveying control module 2, clamping control module 3, and bundling control module 4 are integrated into a programmable logic controller or embedded microprocessor. The control method described in Embodiment 1 is implemented by executing the corresponding computer program, and the modules communicate with each other through an internal bus or signal line.
[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
