Description

Technical Field

[0001] The present disclosure relates to the field of tobacco leaf feeding and water addition regulation, and in particular to a feeder regulation control method, device, electronic device and computer-readable storage medium based on dual control quantities. Background Art

[0002] During the tobacco leaf feeding process, the tobacco leaves absorb flavors. The rotating drum lifts the leaves, which then fall back under their own weight, causing them to flip within the drum. Steam and steam-atomized water then heat, humidify, and feed the leaves. Hot air blows throughout the process, ensuring even heating and feeding. Finally, a dehumidification fan removes excess moisture and impurities. This feeding process improves the tobacco leaves' toughness and processing resistance, ensuring they meet production process requirements.

[0003] However, during the production process of the feeder, there are two factors that affect the uniformity of feeding and water addition, namely the weight of the tobacco leaves and the surface area of ​​the tobacco leaves. During the production process, a system can be designed to calculate the real-time feed and water addition amount of the feeder based on the real-time incoming material weight flow rate or the real-time incoming material surface area flow rate. However, in actual applications, there is no correlation or a small degree of correlation between the incoming material weight flow rate and the surface area flow rate, so most of the feeder production is controlled by calculating the tobacco leaf weight flow rate. In this way, changes in the tobacco leaf surface area flow rate may cause an increase in the error in the tobacco leaf's absorption of moisture and spices. When the control system controls according to the tobacco leaf weight flow rate error, although it executes according to the control parameters, the tobacco leaf moisture and spice absorption detected in the next process level will fluctuate greatly.

[0004] Therefore, one or more methods are needed to solve the above problems.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0050] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the drawings represent like or similar parts, and thus repetitive description thereof will be omitted.

[0051] In addition, the described features, structures or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure can be practiced without one or more of the specific details, or other methods, components, materials, devices, steps, etc. can be adopted. In other cases, well-known structures, methods, devices, implementations, materials or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0052] The blocks shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. Specifically, these functional entities may be implemented in software, or in one or more software-hardened modules, or in different networks and / or processor devices and / or microcontroller devices.

[0053] In this exemplary embodiment, a feeder adjustment control method based on dual control amount is first provided; Figure 1 As shown in , the feeder adjustment control method based on dual control amount may include the following steps:

[0054] Step S110, based on the process flow of the feeder, calculate the preset dual flow of the material to generate a material flow error value;

[0055] Step S120, based on the material weight value, by weighting the material flow error value to generate a material parameter value;

[0056] Step S130 , based on the material parameter value, the input parameters of the PID controller are set to complete the regulation and control of the feeder.

[0057] In an exemplary embodiment of the present disclosure, a method for regulating and controlling a feeder based on dual control quantities is disclosed, wherein the method comprises: generating a material flow error value by calculating a preset dual flow rate of a material based on the feeder process flow; generating a material parameter value by weighting the material flow error value based on a material weight value; and completing regulation and control of the feeder by setting input parameters of a PID controller based on the material parameter value. By inputting dual flow target weighted values ​​into the PID controller, the present disclosure solves the problem of simultaneously considering both weight flow target and surface area flow target, thereby improving the control accuracy of the feeder.

[0058] Next, a feeder adjustment control method based on dual control quantities in this exemplary embodiment will be further described.

[0059] In the template configuration step S110 , a material flow error value may be generated by calculating a preset double flow of the material based on the process flow of the feeder.

[0060] In the embodiment of this example, first, based on a comprehensive flow regression analysis of multiple batches of materials of the same brand, a statistically average target material surface area flow value and target material weight flow value are obtained through calculation for the purpose of stable moisture and uniform penetration of liquid materials.

[0061] Afterwards, an industrial camera installed on the upstream thinning belt captures an image of the tobacco leaf material. The image recognition system calculates the surface area of ​​the tobacco leaf material in the image and further calculates the current surface area flow rate of the tobacco leaf material, that is, the surface area of ​​the tobacco leaf material passing through per hour.

[0062] Finally, the current tobacco material weight flow value is obtained from the upstream electronic belt scale, that is, the weight of the tobacco material passing through per hour.

[0063] In the embodiment of this example, in order to achieve precise control of the feeder using the tobacco material weight flow rate and the tobacco material surface area flow rate at the same time, the tobacco material weight flow rate error value and the tobacco material surface area flow rate error value can be obtained at the same time.

[0064] First, set the target material surface area flow rate value as S1, the current material surface area flow rate value as S2, and the material surface area flow rate error value as Se. The error between the current material surface area flow rate value and the target material surface area flow rate value is the material surface area flow rate error value. In other words, S2-S1=Se.

[0065] When the target material surface area flow rate value is greater than the preset current material surface area flow rate value, the material surface area flow rate error value is a negative value, that is, Se<0;

[0066] When the target material surface area flow rate value is less than the preset current material surface area flow rate value, the material surface area flow rate error value is a positive value, that is, Se>0;

[0067] Next, set the target material weight flow value to V1, the current material weight flow value to V2, and the material weight flow error value to Ve. The error between the current material weight flow value and the target material weight flow value is used as the material weight flow error value. That is, V2 - V1 = Ve.

[0068] When the target material weight flow value is greater than the preset current material weight flow value, the material weight flow error value is a negative value; that is, Ve<0;

[0069] When the target material weight flow value is less than the preset current material weight flow value, the material weight flow error value is a positive value; that is, Ve>0;

[0070] In summary, we can simultaneously obtain the material surface area flow rate error value and the material weight flow rate error value, that is, the material flow rate error value of tobacco leaves.

[0071] In the template configuration step S120 , the material parameter value may be generated by weighting the material flow error value based on the material weight value.

[0072] In the embodiment of this example, the feeder has different accuracy requirements for the material surface area flow error value and the material weight flow error value due to the production of tobacco materials of different brands and different seasonal batches. That is, the first weight value corresponding to the material surface area flow error value and the second weight value corresponding to the material weight flow error value are different. Therefore, except for the initial commissioning operation, the weight values ​​can be averaged (that is, the first weight value is 0.5 and the second weight value is 0.5). After that, the weight values ​​need to be adjusted according to the actual situation.

[0073] At the same time, in order to meet the production process requirements, the sum of the first weight value and the second weight value is set to 1.

[0074] For example, when the upstream feeding system is very stable, with strict weight requirements, and the weight flow rate remains stable, but the tobacco leaves are of various types and have large size differences, the second weight value corresponding to the weight flow error value can be appropriately reduced, and the first weight value corresponding to the surface area flow error value can be increased.

[0075] When the batch of tobacco materials supplied by the upstream feeding system contains a large number of tobacco leaves of the same type and the tobacco leaves are of relatively constant size, the second weight value corresponding to the weight flow error value can be appropriately increased, and the first weight value corresponding to the surface area flow error value can be reduced.

[0076] In this example embodiment, the first weight value is set to A and the second weight value is set to B. The first parameter value is obtained by multiplying the material surface area flow rate error value by the first weight value. That is, the first parameter value is: A*Se.

[0077] The second parameter value is obtained by multiplying the material weight flow error value by the second weight value. That is, the second parameter value is: B*Ve.

[0078] It should be noted that because the material surface area flow error value and the material weight flow error value have positive and negative values, the first parameter value and the second parameter value also have positive and negative values.

[0079] Then, the first parameter value and the second parameter value are simultaneously introduced into the PID controller as input material parameter values ​​of the PID controller.

[0080] In the template configuration step S130 , the feeder can be regulated and controlled by setting the input parameters of the PID controller based on the material parameter values.

[0081] In this exemplary embodiment, a statistically averaged target water addition control amount and target flavoring control amount are calculated based on a comprehensive control amount regression analysis of multiple batches of the same brand. The target water addition control amount represents the target water absorption by the tobacco leaves expected to be achieved by the feeder process, and the target flavoring control amount represents the target flavoring absorption by the tobacco leaves expected to be achieved by the feeder process.

[0082] When there is an error between the target material surface area flow value and the current material surface area flow value, or when there is an error between the target material weight flow value and the current material weight flow value, the PID controller can be controlled to output the corresponding adjustment control amount to control the amount of material added or the amount of water added.

[0083] That is, the material parameter value and the target water addition control amount are added and input into the PID controller to obtain a water addition adjustment amount.

[0084] The material parameter value and the target feeding control amount are added and input into the PID controller to obtain a feeding adjustment amount.

[0085] In this exemplary embodiment, the amount of water added is controlled by the production line's electrical control cabinet. An electronic scale sends incoming material signals to the electronic control system, which compares the set water addition amount with the amount detected by the electromagnetic flowmeter. This system then controls the opening of the pneumatic control valve to adjust the amount of water added. This allows the humidifying water flow rate to vary based on the tobacco material flow rate measured by the electronic scale, thus achieving automatic, proportional, and quantitative water addition.

[0086] That is, when the water addition adjustment amount is greater than the target water addition control amount (when the material parameter value input to the PID controller is a negative number), the adjustment control of the feeder is completed by reducing the opening of the pneumatic regulating valve.

[0087] When the water addition adjustment amount is less than the target water addition control amount (when the material parameter value input to the PID controller is a positive number), the adjustment control of the feeder is completed by increasing the opening of the pneumatic regulating valve;

[0088] The amount of material added is also controlled by the production line's electrical control cabinet. The electronic scale sends the measured incoming material signal to the electronic control system, which compares the set amount of material added with the amount detected by the mass flow meter. The inverter output frequency is then controlled to change the speed of the feed pump motor. This causes the flow rate of the feed pump to change according to the material flow rate measured by the electronic scale, thus achieving automatic control of quantitative feeding according to the ratio.

[0089] That is, when the feeding adjustment amount is greater than the target feeding control amount (when the material parameter value input to the PID controller is a negative number), the feeding pump motor speed is reduced to complete the adjustment control of the feeding machine;

[0090] When the feeding adjustment amount is less than the target feeding control amount (when the material parameter value input to the PID controller is a positive number), the feeding machine is regulated and controlled by increasing the feeding pump motor speed.

[0091] Through weighted parallel control based on the material weight flow error value and the material surface area flow error value, the PID controller can give the control quantity of the feeder according to the weighted output values ​​of the two targets, so as to solve the problem of the feeder losing sight of the weight flow target and the surface area flow target at the same time, thereby improving the accuracy of the feeder control.

[0092] It should be noted that although the steps of the method disclosed herein are depicted in a particular order in the accompanying drawings, this does not require or imply that the steps must be performed in that particular order, or that all steps must be performed to achieve the desired result. Additionally or alternatively, certain steps may be omitted, multiple steps may be combined into one, and / or one step may be decomposed into multiple steps.
