Description

Technical Field

[0001] This invention relates to the field of tobacco processing technology, and in particular to a method, apparatus, electronic device, and storage medium for controlling the unloading of tobacco shreds during the blending process. Background Technology

[0002] In actual production, when a batch of tobacco is finished, if the next batch is of a different brand, the remaining material of the current brand in the feeder of the blending material section and the downstream electronic belt scale must be completely unloaded (i.e., "cleaning") to avoid mixing of brands.

[0003] The current material handling process is generally as follows: First, the operator switches the feeder's control mode from "automatic" to "manual" on the segment control system interface (usually the feeder's local or area controller). Simultaneously, on the electronic belt scale's independent control instrument or interface, the operator also switches its control mode from "automatic" to "manual." Afterward, based on experience, the operator manually starts the belt scale and then manually starts the feeder to unload, manually stopping it according to the material conditions. After unloading is complete, a crucial and easily overlooked step is that the operator must switch the control modes of both the feeder and the electronic belt scale back to "automatic" on both systems.

[0004] However, current unloading control methods require operators to perform multiple mode switching and manual start / stop operations on at least two independent control interfaces. This involves numerous steps, low efficiency, and the speed matching and timing of manual unloading rely on personal experience, resulting in poor stability. Furthermore, in high-intensity, fast-paced production environments, operators are highly likely to forget or neglect to switch the equipment back to "automatic" mode after completing manual unloading, leading to serious safety hazards. Summary of the Invention

[0005] This invention provides a method, device, electronic equipment, and storage medium for controlling the unloading of tobacco shreds in the blending process, which greatly simplifies the operation process, improves unloading efficiency, and enhances the stability and safety of the unloading process.

[0006] According to one aspect of the present invention, a method for controlling the unloading of tobacco shreds in a blending process is provided, applied to a segment control PLC. The segment control PLC integrates a semi-automatic unloading control module, which, upon receiving a signal that the blending process is in the cleaning stage (switching from a first blending section to a second blending section), takes over control of the target equipment. The method includes: In response to a first instruction sent by the central control system, the semi-automatic unloading control module is activated, and the module is controlled to execute an unloading start sequence and send a first signal to the central control system. The first instruction indicates that the current blending process is in the material cleaning stage, switching from the first blending section to the second blending section. The unloading start sequence indicates the unloading operation information of the target equipment. The first signal informs the central control system that control of the target equipment has been locked. In response to a second command sent by the central control system, the semi-automatic unloading control module is controlled to execute a safety stop sequence to stop the target equipment; the safety stop sequence is related to stopping the target equipment. When the safety stop sequence is completed, the target device is controlled to enter fully automatic mode, and a second message is sent to the central control system. The semi-automatic unloading control module is also controlled to shut down, so that the central control system can take over the production of the second blending section in a fully automatic manner. The second message includes that the control of the target device has been unlocked and that the target device has entered fully automatic mode.

[0007] According to another aspect of the present invention, a tobacco unloading control device for a blending process is provided, applied to a segment control PLC. The segment control PLC integrates a semi-automatic unloading control module. The semi-automatic unloading control module is used to take over control of the target equipment after receiving a signal that the blending process is in the cleaning stage, switching from the first blending section to the second blending section. The device includes: The first information processing module is used to respond to a first instruction sent by the central control system, activate the semi-automatic unloading control module, control the semi-automatic unloading control module to execute the unloading start sequence, and send a first signal to the central control system; the first instruction is used to indicate that the current blending process is in the material cleaning stage of switching from the first blending section to the second blending section; the unloading start sequence is used to indicate the unloading operation information of the target equipment; the first signal is used to inform the central control system that the control of the target equipment has been locked. The second information processing module is used to respond to a second instruction sent by the central control system and control the semi-automatic unloading control module to execute a safety stop sequence to stop the target equipment; the safety stop sequence is related to stopping the target equipment. The third information processing module is used to control the target equipment to enter fully automatic mode when it is determined that the safety stop sequence has been completed, and to send second information to the central control system, and to control the semi-automatic unloading control module to shut down so that the central control system can take over the production of the second blending section in a fully automatic manner; the second information includes that the control of the target equipment has been unlocked and that the target equipment has entered fully automatic mode.

[0008] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising: At least one processor; and A memory communicatively connected to the at least one processor; wherein, The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the tobacco unloading control method for the blending process according to any embodiment of the present invention.

[0009] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the tobacco unloading control method for the blending process according to any embodiment of the present invention.

[0010] The tobacco unloading control method for the blending process in this invention can be applied to a segment control PLC. The segment control PLC integrates a semi-automatic unloading control module. This module, upon receiving a signal that the blending process is in the cleaning stage (switching from the first blending section to the second blending section), takes over control of the target equipment to simplify the cleaning operation. Specifically, in response to a first instruction from the central control system, the semi-automatic unloading control module is activated and controls it to execute the unloading start sequence, and sends a first signal to the central control system. The first instruction indicates that the current blending process is in the cleaning stage (switching from the first blending section to the second blending section); the unloading start sequence indicates the target equipment's unloading operation information, achieving automated cleaning and improving unloading efficiency; the first signal informs the central control system that control of the target equipment has been locked, providing a real-time reminder that the target equipment is occupied. This means that the full-process automatic formulation instructions issued by the central control system will be temporarily blocked to prevent instruction conflicts and ensure the cleaning process is completed safely and accurately, greatly avoiding the mixing of tobacco with two different formulations. Then, in response to the second instruction sent by the central control system, the semi-automatic unloading control module is controlled to execute a safety stop sequence to stop the target equipment. The safety stop sequence contains relevant information about stopping the target equipment. This allows for precise control of the timing of stopping the target equipment, and the entire process from start to finish is controlled by instructions sent by the central control system. This avoids the need for multiple interfaces for the cleaning operation, greatly simplifying the cleaning process and automating the process, thus improving the stability and efficiency of the unloading process. Furthermore, once the safety stop sequence is confirmed to be completed, the target equipment is controlled to enter fully automatic mode, and a second message is sent to the central control system. The semi-automatic unloading control module is also controlled to shut down, allowing the central control system to automatically take over the production of the second blending section. The second message includes that the control of the target equipment has been unlocked and that the target equipment has entered fully automatic mode. This unlocks the target equipment after cleaning and promptly informs the central control system that it can take over the production of the target equipment in the second blending section. This greatly avoids situations where operators forget or neglect to switch the equipment back to fully automatic mode after completing manual unloading, fundamentally eliminating the risk of "mode forgetting" and providing safety throughout the entire process.

Detailed Implementation

[0014] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0015] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0016] Example 1 Figure 1This is a flowchart illustrating a method for controlling the unloading of tobacco shreds in a blending process, provided by an embodiment of the present invention. This embodiment is applicable to situations where, after the production of one batch of tobacco shreds is completed, if the next batch is of a different grade, the remaining material of the current grade in the feeder of the blending material section and the downstream electronic belt scale must be completely unloaded. This method can be executed by a tobacco shred unloading control device for the blending process. This tobacco shred unloading control device for the blending process can be implemented in hardware and / or software, and can be configured in any electronic device with network communication capabilities. Figure 1 As shown, the method for controlling the unloading of tobacco shreds in the blending process of the present invention may include the following steps: S110. In response to the first instruction sent by the central control system, activate the semi-automatic unloading control module, control the semi-automatic unloading control module to execute the unloading start sequence, and send a first signal to the central control system; the first instruction is used to indicate that the current blending process is in the material cleaning stage of switching from the first blending section to the second blending section; the unloading start sequence is used to indicate the target equipment to execute the unloading operation information; the first signal is used to inform the central control system that the control of the target equipment has been locked.

[0017] This invention relates to a tobacco unloading control method for the blending process, applied to a segment control PLC. The segment control PLC integrates a semi-automatic unloading control module. This module takes over control of the target equipment upon receiving a signal indicating that the blending process is transitioning from the first blending section to the cleaning stage (switching to the second blending section). The segment control PLC serves as a secondary control node between the equipment PLC and the central control system (MES). The segment control PLC can uniformly manage all equipment within the blending section, collecting real-time signals such as flow rate, weight, material level, photoelectric sensors, and speed. It then reports the status to the higher-level central control system and issues precise control commands to the lower-level equipment.

[0018] Specifically, during the fully automated takeover of the first blending stage, when the central control system receives a notification that the second blending stage will begin production in the next phase, and that the blending formulas for the first and second blending stages are different, the central control system will issue a first instruction to the segment control PLC when the first blending stage is nearing completion. The segment control PLC will then activate the semi-automatic unloading control module based on this instruction and take over the target equipment. This means the target equipment will only follow the fully automated process instructions from the segment control PLC and will automatically ignore the fully automated mode instructions from the central control system. The segment control PLC will then control the semi-automatic unloading control module to execute the unloading start sequence, meaning the target equipment will execute the unloading operation information according to the unloading start sequence instructions, thus controlling the operation of the target equipment.

[0019] Optionally, the target equipment may include a feeder and an electronic belt scale; for example, such as Figure 2As shown, the electronic belt scale can be the main blade tobacco scale and the airflow tobacco scale. The unloading start sequence can include: first, sending a start command to the electronic belt scale; when the electronic belt scale reaches the first preset unloading speed and the electronic belt scale is confirmed to be running stably, then sending a start command to the feeder and controlling the feeder to run at a speed that matches the running speed of the electronic belt scale.

[0020] In an embodiment of the present invention, optionally, the display interface of the central control system includes a second control; the second control is used to activate the semi-automatic unloading control module; the first instruction is generated by triggering the second control. For example, the display interface of the central control system is configured with a second control specifically for "semi-automatic unloading start". When the second control is triggered, the central control system generates a corresponding first instruction and sends the first instruction to the segment control PLC. The segment control PLC, according to the first instruction, activates the semi-automatic unloading control module and controls the semi-automatic unloading control module to execute the unloading start sequence, and sends a first signal to the central control system. In this embodiment of the present invention, by triggering the second control on the display interface of the central control system, the central control system issues a first instruction, avoiding the need for operators to manually unload on the display interfaces of multiple target devices, greatly simplifying the unloading process, significantly reducing reliance on personal experience, and achieving a more precise control process.

[0021] Optionally, in an embodiment of the present invention, after activating the semi-automatic unloading control module, the method further includes: sending third information to the central control system; the third information is used to instruct the activation of a first control on the display interface of the central control system; the first control is used to control the operating status of the target equipment, and the first control is only activated on the display interface of the central control system after the semi-automatic unloading control module is activated, so that during the material clearing process, the operator can monitor the flow rate on the central control system and make fine adjustments to the operating status of the target equipment according to the timing. That is, the present invention provides the ability to automatically control the operation of the target equipment through the semi-automatic unloading control module, and can also actively and flexibly make fine adjustments according to the material conditions on site, avoiding the arbitrariness and instability of completely manual operation, and realizing a safe combination of "manual decision-making" and "automatic execution", that is, achieving a balance between flexibility and controllability.

[0022] Optionally, the first control may include an acceleration control, a deceleration control, and a jog control. The jog control process can be as follows: triggering the jog control once will cause the target device to receive control information indicating that it will run at a preset speed for a preset time. Specifically, when the current blending process is in the material clearing stage of switching from the first blending section to the second blending section, and the target device has entered a stable unloading state, upon receiving control information from the central control system, the operating state of the target device is controlled based on the control information; control commands are generated by triggering the first control. For example, when the target device is a feeder, after the feeder enters a stable unloading state, the operator can monitor the flow rate on the display interface of the central control system and, according to the actual situation, fine-tune the feeder by triggering the acceleration control, deceleration control, or jog control to optimize the material clearing effect; the speed of the electronic belt scale is usually kept constant.

[0023] Optionally, the method further includes: if a fault signal is detected from the target device, controlling the target device to stop and sending fault information to the central control system. For example, the segment control PLC continuously monitors the operating status of the target device. If a device fault (such as motor overload or material blockage) is detected during the unloading process, the unloading process will be automatically interrupted, a safe shutdown will be performed, and an alarm prompt will be displayed on the central control system's display interface; ensuring the safe operation of the equipment.

[0024] S120, in response to the second instruction sent by the central control system, controls the semi-automatic unloading control module to execute a safety stop sequence to stop the target equipment; the safety stop sequence is related to stopping the target equipment.

[0025] The second instruction indicates that the remaining material in the first blending section has been cleaned up.

[0026] Specifically, the central control system uses the unloading information such as flow rate, weight, and material level sent by the segment control PLC to determine that the remaining material in the first blending section has been cleaned up. Then, the central control system sends a second instruction to the segment control PLC. According to the second instruction, the segment control PLC controls the semi-automatic unloading control module to execute a safety stop sequence to stop the target equipment.

[0027] Optionally, the target equipment includes a feeder and an electronic belt scale; the safety stop sequence may include: first controlling the feeder to stop, then waiting for a preset time, and then controlling the electronic belt scale to stop.

[0028] In an embodiment of the present invention, optionally, the display interface of the central control system includes a third control; the third control is used to inform the semi-automatic unloading control module that the target equipment has completed unloading: the second instruction is generated by triggering the third control. For example, the display interface of the central control system is configured with a third control specifically for "semi-automatic unloading completed". When the third control is triggered, the central control system generates a corresponding second instruction and sends it to the segment control PLC. The segment control PLC controls the semi-automatic unloading control module to execute a safety stop sequence, that is, first controlling the feeder to stop, then waiting for a preset time, and then controlling the electronic belt scale to stop. In this embodiment of the present invention, by triggering the third control on the display interface of the central control system, the central control system issues a second instruction, avoiding the need for operators to manually control the equipment to stop on the display interfaces of multiple target devices. This greatly simplifies the unloading process, significantly reduces reliance on personal experience, lowers labor intensity and skill requirements, and significantly improves the efficiency of material clearing operations.

[0029] S130. When the safe stop sequence is completed, the target equipment is controlled to enter the fully automatic mode and a second message is sent to the central control system. The semi-automatic unloading control module is also controlled to shut down so that the central control system can take over the production of the second blending section in a fully automatic manner. The second message includes that the control of the target equipment has been unlocked and that the target equipment has entered the fully automatic mode.

[0030] For example, once the safety stop sequence is completed, the control mode of the feeder and electronic belt scale is seamlessly and forcibly restored to "fully automatic mode," and a "equipment release" and "fully automatic mode restoration" signal is sent to the central control system. At the same time, the semi-automatic unloading control module is shut down so that the central control system can automatically take over the production of the second blending section.

[0031] Through the logical design of the system, this invention forces the equipment control mode to automatically return to fully automatic mode after the unloading task is completed. The step of returning to fully automatic mode is a step guaranteed by the system and cannot be skipped or omitted. This fundamentally eliminates major quality accidents caused by the equipment remaining in manual mode due to operator negligence, and the safety is revolutionaryly improved.

[0032] The tobacco unloading control method for the blending process in this invention can be applied to a segment control PLC. The segment control PLC integrates a semi-automatic unloading control module. This module, upon receiving a signal that the blending process is in the cleaning stage (switching from the first blending section to the second blending section), takes over control of the target equipment to simplify the cleaning operation. Specifically, in response to a first instruction from the central control system, the semi-automatic unloading control module is activated and controls it to execute the unloading start sequence, and sends a first signal to the central control system. The first instruction indicates that the current blending process is in the cleaning stage (switching from the first blending section to the second blending section); the unloading start sequence indicates the target equipment's unloading operation information, achieving automated cleaning and improving unloading efficiency; the first signal informs the central control system that control of the target equipment has been locked, providing a real-time reminder that the target equipment is occupied. This means that the full-process automatic formulation instructions issued by the central control system will be temporarily blocked to prevent instruction conflicts and ensure the cleaning process is completed safely and accurately, greatly avoiding the mixing of tobacco with two different formulations. Then, in response to the second instruction sent by the central control system, the semi-automatic unloading control module is controlled to execute a safety stop sequence to stop the target equipment. The safety stop sequence contains relevant information about stopping the target equipment. This allows for precise control of the timing of stopping the target equipment, and the entire process from start to finish is controlled by instructions sent by the central control system. This avoids the need for multiple interfaces for the cleaning operation, greatly simplifying the cleaning process and automating the process, thus improving the stability and efficiency of the unloading process. Furthermore, once the safety stop sequence is confirmed to be completed, the target equipment is controlled to enter fully automatic mode, and a second message is sent to the central control system. The semi-automatic unloading control module is also controlled to shut down, allowing the central control system to automatically take over the production of the second blending section. The second message includes that the control of the target equipment has been unlocked and that the target equipment has entered fully automatic mode. This unlocks the target equipment after cleaning and promptly informs the central control system that it can take over the production of the target equipment in the second blending section. This greatly avoids situations where operators forget or neglect to switch the equipment back to fully automatic mode after completing manual unloading, fundamentally eliminating the risk of "mode forgetting" and providing safety throughout the entire process.
