Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0017] The ventilation of heated cigarettes is a crucial indicator affecting the sensory experience of smoking. However, with numerous heated cigarette brands, even under identical parameters such as cigarette running speed, laser perforation device parameters, and glue supply pressure, the ventilation of cigarettes produced varies significantly across brands. Furthermore, cigarette running speed and glue supply pressure also significantly impact ventilation; faster running speed results in greater ventilation, and lower glue supply pressure also increases ventilation. Due to the combined influence of these factors, manually adjusting the laser perforation device parameters makes it difficult to quickly and stably control the cigarette ventilation near the target value. Changes in any factor, without timely parameter adjustments, can cause the ventilation to deviate from the target value and eventually exceed the acceptable range. To address these technical problems, this application discloses a method for controlling cigarette ventilation, enabling rapid and stable adjustment of cigarette ventilation.

[0018] See Figure 1 As shown, this invention discloses a method for controlling the ventilation of a cigarette, applied to a cigarette laser drilling device, comprising: Step S11: Obtain the target control signal sent by the target cigarette rolling unit, and perform perforation on the target cigarette on the cigarette laser perforation device based on the target control signal; the target cigarette rolling unit and the cigarette laser perforation device communicate via a bus.

[0019] In this embodiment, the existing subsystems of the cigarette rolling machine are used to construct a composite control system for cigarette ventilation that allows for coordinated control of each subsystem. The system architecture diagram is shown below. Figure 2As shown, when external interference causes the ventilation control to deviate from the stable state and target value, the system automatically adjusts parameters internally to bring the cigarette ventilation control back to a stable state and near the target value after a brief fluctuation. Specifically, the communication between the cigarette laser perforation device and the target cigarette rolling unit has been upgraded from the original hard-wired method to a bus communication method, simplifying wiring, reducing the failure rate caused by wiring issues, and establishing a standard data communication interface based on EtherCAT bus transmission.

[0020] In this embodiment, Figure 2 The cigarette airtightness testing device collects raw cigarette data and sends the pre-processed cigarette ventilation data to the detection data processing module of the cigarette rolling and sealing unit's IPC (Industrial Personal Computer) control system. Cigarette airtightness testing devices are now widely used in traditional cigarette rolling and sealing units, and the technology is relatively mature. The main function of the detection data processing module is to group and plan the cigarette ventilation detection data sent by the cigarette airtightness testing device, screen for abnormal data, and calculate the average value. Considering that the left and right tracks of the laser are controlled by two sets of laser drilling time parameters, and that the left and right tracks of the laser correspond to the front and rear tracks of the cigarette respectively, the cigarette ventilation data can be divided into left track front row, left track rear row, right track front row, and right track rear row for convenient data monitoring and transmission. Simultaneously, detection data interaction modules are deployed on both the target cigarette rolling and sealing unit and the cigarette laser drilling device, and data transmission between the cigarette rolling and sealing unit and the laser drilling device is performed according to the designed communication protocol. Figure 3 The diagram illustrates the cigarette transfer process. First, the cigarette is perforated by the target laser drilling device, then transferred from the laser drilling wheel to the reduction wheel, and then from the reduction wheel to several subsequent drums. Finally, it is transferred to the detection wheel equipped with a cigarette airtightness detection device for ventilation testing. As can be seen from the above process design, the cigarette airtightness detection device lags behind the laser drilling device (actuator) in time (e.g., while the laser drilling device is drilling the 100th cigarette, the airtightness detection device may only be testing the ventilation of the 1st cigarette). The current data detected by the airtightness detection device is historical data for the laser. If the controller uses outdated information for decision-making, it may lead to system overshoot, long steady-state time, weakened anti-interference ability, and even stability risks such as oscillation and instability. Therefore, it is necessary to design data transmission and reception rules between the cigarette airtightness testing device and the laser perforation device. Since the data transmission between the cigarette airtightness testing device and the target cigarette rolling unit IPC is synchronous, only the data interaction rules between the rolling unit IPC and the cigarette laser perforation device (Laser) need to be designed. Specifically, such as... Figure 4 The diagram shows the data interaction process on the side of the laser drilling device. Figure 5This is a schematic diagram of the data interaction process on the target winding unit side.

[0021] In this embodiment, as Figure 4 As shown, when the cigarette laser punching device is stationary, the data flag bits are initialized. If a target control signal is received from the target cigarette rolling unit IPC, the target cigarette on the cigarette laser punching device will be punched based on the target control signal.

[0022] Step S12: Send a target data acquisition request to the target cigarette rolling machine to receive target feedback data acquired and sent by the target cigarette rolling machine based on a preset data interaction rule; the target feedback data is the ventilation data corresponding to the target cigarette; the preset data interaction rule includes a preset data delay acquisition rule.

[0023] In this embodiment, the cigarette laser perforation device sends a target data acquisition request to the target cigarette rolling unit to receive target feedback data acquired and sent by the target cigarette rolling unit based on preset data interaction rules. Simultaneously with sending the target data acquisition request, the cigarette laser perforation device resets the corresponding data reception flag. After receiving the feedback data sent by the IPC and the corresponding flag setting signal, it reads the target feedback data, resets the data request flag, and sets the data received flag. It can be understood that the target feedback data is the ventilation data corresponding to the target cigarette; the preset data interaction rules include preset data delay acquisition rules.

[0024] In this embodiment, the specific process of sending target feedback data to the cigarette laser drilling device by the target cigarette rolling unit based on preset data interaction rules includes: the target cigarette rolling unit acquiring cigarette ventilation data corresponding to the drilling time period of the target cigarette from the cigarette airtightness detection device based on preset data delay acquisition rules, processing the cigarette ventilation data to obtain target feedback data corresponding to the target cigarette, and then sending the target feedback data to the cigarette laser drilling device based on preset data interaction rules. The preset data delay acquisition rules are rules used to acquire cigarette ventilation data based on a target delay time. The target delay time includes a first delay time and a second delay time. The first delay time is the delay time determined based on the cigarette slot position difference between the cigarette airtightness detection device and the cigarette laser drilling device, and the second delay time is the delay time determined based on a preset number of cigarettes.

[0025] In one specific implementation, when the target cigarette rolling and sealing unit is stationary, the data and data flag bits are initialized. After initialization, the target cigarette rolling and sealing unit enters automatic operation mode. The cigarette laser perforation device operates, and the cigarette airtightness detection device operates. Upon receiving a data request from the cigarette laser perforation device, the IPC delays for S+N DCP times (i.e., the target delay time) before sending feedback data to the cigarette laser perforation device and setting a new data flag bit. Here, S is the difference between the cigarette airtightness detection device's detection and the laser's slot position, and the preset cigarette quantity N is the average number of cigarettes determined based on the cigarette running speed on the target cigarette rolling and sealing unit, which can be manually adjusted. Then, the data reception flag bit fed back by the Laser is checked; after confirming data reception, the new data flag bit is cleared. Finally, when the target cigarette rolling and sealing unit is stationary, the process ends. Otherwise, the next round of data transmission will begin.

[0026] Step S13: Update the target time parameter of the cigarette laser drilling device based on the target feedback data, so as to perform the cigarette drilling operation based on the updated target time parameter; the target time parameter is the laser drilling time parameter corresponding to the cigarette laser drilling device.

[0027] In this embodiment, after obtaining the target feedback data, the target time parameter of the cigarette laser drilling device can be updated based on the target feedback data, so that the cigarette drilling operation can be performed based on the updated target time parameter. The target time parameter is the laser drilling time parameter corresponding to the cigarette laser drilling device. It can be understood that the cigarette ventilation... Venti The main interfering factors are the cigarette travel speed. v , spraying adhesive and pressing p The relationship between cigarette ventilation, cigarette running speed, and adhesive spraying pressure can be used as a target control function, expressed as: ; Spray adhesive pressing p With the speed of cigarette movement v There exists a linear relationship; the two relationships can be expressed as: ; in g As a linear function, the adhesive spraying pressure p With the speed of the cigarette v It increases and increases, and based on this, we can conclude: ; The speed of cigarette movement v When constant, the ventilation of cigarettes is measured through global sample measurements. Venti With adhesive spraying and pressing p Negative correlation, assuming Venti Follow pIf it is strictly monotonically decreasing and continuously differentiable, then the following holds: ; In actual operation, when the cigarette travel speed v When the size increases, if the laser drilling time parameter remains constant, the ventilation of the cigarette will increase. Venti It will increase, because the start-up speed of formal production is 1500 units / minute, assuming... In the domain v ∈[1500,8000] is continuously differentiable, assuming Venti Follow v If it is monotonically increasing, then the following exists: ; Cigarette ventilation Venti Overall, it depends on the speed of the cigarette. v Increases and gradually increases, with the pressure of the adhesive spray. p The correlation is weakly negative, therefore the relationship between cigarette ventilation, cigarette running speed, and adhesive spraying pressure can be integrated and expressed as: ; F ( v ) is in the domain v A function that is continuously differentiable and monotonically increasing within the range [1500, 8000].

[0028] Laser drilling time T This is an important parameter for controlling the laser's power output. It is also related to the cigarette's running speed. v and spray adhesive pressing p Different interference factors affect laser drilling time. T As a control variable for the actuator, it is used to actively adjust the laser power output to control the cigarette ventilation. Based on the above analysis, when updating the target time parameters of the cigarette laser drilling device based on the target feedback data, a target control function can be used to update the target time parameters of the cigarette laser drilling device based on the target feedback data and the target ventilation. That is to say, the target control function is a control function between the cigarette running speed, the adhesive spraying pressure, and the cigarette ventilation of the cigarette laser drilling device, and the cigarette ventilation and the cigarette running speed satisfy a preset positive correlation, while the cigarette ventilation and the adhesive spraying pressure satisfy a preset weak negative correlation.

[0029] In this embodiment, as Figure 6 As shown, the cigarette ventilation control system employs a composite control system combining piecewise linear control and PID control. The controller design of this composite control system uses a "feedforward + feedback" control method, updating the laser drilling time using the controller's output. T Feedforward control employs piecewise linear control, and the cigarette running speed... vIt is a significant and observable disturbance factor affecting the ventilation of cigarettes, therefore it is used as the disturbance quantity in piecewise linear control. Feedback control employs PID control, precisely adjusting the laser drilling time based on the error value. T The laser output power is further controlled to ultimately adjust the ventilation of the cigarette after it has been perforated. The final laser perforation time (i.e., the target time parameter) output based on the target feedback data can be expressed as: ; Among them, laser drilling time T It is composed of three superimposed parts, among which T b This is the initial value for the drilling time. T s The piecewise linear control component of the drilling time (i.e., the first time parameter). T pid This refers to the PID control component (i.e., the second time parameter) for the drilling time. In other words, this embodiment utilizes a target control function to update the target time parameter of the cigarette laser drilling device based on target feedback data and target ventilation. Specifically, this includes: using the target control function to determine a first time parameter based on target feedback data, target ventilation, and cigarette running speed; and determining a second time parameter based on the first time parameter, target feedback data, and target ventilation; updating the target time parameter of the cigarette laser drilling device based on the first and second time parameters. The first time parameter is a feedforward time parameter used for piecewise linear control of the cigarette ventilation, and the second time parameter is a feedback time parameter used for PID control of the error value between the target feedback data and the target ventilation.

[0030] In one specific implementation, when the cigarette travel speed v Dramatic changes, such as v The laser drilling speed was increased from 1500 pieces / minute to 8000 pieces / minute. T Constant, cigarette ventilation Venti The speed of the cigarette can also change drastically. If only feedback control is used to adjust the laser drilling time, the system cannot respond quickly due to the inherent lag of the detection system, which may cause the ventilation of some cigarettes to exceed the acceptable range. Based on the above system characteristics, an independent feedforward channel is introduced on the basis of feedback control. When a change in the cigarette running speed is observed, the feedforward control immediately adjusts the output. T s Feedforward control uses piecewise linearization to fit the system characteristic curve to quickly compensate for laser drilling time and improve system response speed. The specific processing method of piecewise linearization is as follows: , m =1,2…8; in T m To compensate for the perforation time parameter value, at the cigarette running speed v m Ventilation of cigarettes Venti The solution is obtained when the target steady state is reached. After feedforward control compensation, there is still a deviation between the cigarette ventilation intensity and the target value. The remaining deviation is then addressed through PID control components. T pid To adjust. The following is the error calculation formula. Y 2( Venti () is the cigarette ventilation test value of the cigarette airtightness testing device. R ( Venti ) is the target value for cigarette ventilation. E ( Venti The error value is the difference between the two: ; The control law generated by the PID control component for the drilling time based on the error value can be expressed as: ; in K p For proportional gain, T i The integral time constant is... T d The differential time constant is set via parameter values. To prevent the controller output from going out of control under special circumstances, an output amplitude limit is designed, as follows: ; in T pid_max and T pid_min The maximum and minimum limit values ​​output by the PID controller are set via parameters.

[0031] This embodiment constructs a dynamic model of cigarette ventilation by qualitatively analyzing various process indicators affecting cigarette ventilation, and designs a corresponding composite control system based on the dynamic model, achieving stable control of cigarette ventilation under different operating conditions. Through this composite control method, the control system can adaptively adjust the laser drilling time parameter. The control algorithm can automatically track the optimal laser drilling time value when the cigarette ventilation reaches the target stable state under different operating conditions. The laser in the laser drilling device is the execution unit; the laser drilling time parameter serves as the laser's input, controlling the laser's output power. The laser drills holes in the cigarette, ultimately adjusting the cigarette ventilation. Furthermore, if the target time parameter is detected to have been updated, the cigarette drilling operation is performed based on the updated target time parameter after a third delay time.

[0032] As can be seen, this application simplifies the wiring and reduces the failure rate by optimizing the communication method between the cigarette rolling unit and the laser drilling device from hard-wired communication to bus communication. When interacting with the target cigarette rolling unit based on preset data interaction rules, the target cigarette rolling unit will obtain the ventilation data of the target cigarette corresponding to the time the laser drilling device issues the target data acquisition request, based on the preset data delay acquisition rule in the preset data interaction rules. This ventilation data is then identified as target feedback data, so that the laser drilling device can update the target time parameter based on this target feedback data. Thus, when external interference causes the ventilation control to deviate from the stable state and target value, the target time parameter is automatically adjusted to allow the cigarette ventilation control to return to the stable state and near the target value after a short fluctuation, achieving rapid and stable adjustment of the cigarette ventilation.

[0033] See Figure 7 As shown, this application discloses a cigarette ventilation control device, applied to a cigarette laser drilling device, comprising: The first cigarette punching module 11 is used to acquire the target control signal sent by the target rolling and forming unit, and punch the target cigarette on the cigarette laser punching device based on the target control signal; the target rolling and forming unit and the cigarette laser punching device communicate via a bus. The feedback data acquisition module 12 is used to send a target data acquisition request to the target cigarette rolling unit to receive target feedback data acquired and sent by the target cigarette rolling unit based on a preset data interaction rule; the target feedback data is the ventilation data corresponding to the target cigarette; the preset data interaction rule includes a preset data delay acquisition rule; The second cigarette punching module 13 is used to update the target time parameter of the cigarette laser punching device based on the target feedback data, so as to perform the cigarette punching operation based on the updated target time parameter; the target time parameter is the laser punching time parameter corresponding to the cigarette laser punching device.

[0034] As can be seen, this application simplifies the wiring and reduces the failure rate by optimizing the communication method between the cigarette rolling unit and the laser drilling device from hard-wired communication to bus communication. When interacting with the target cigarette rolling unit based on preset data interaction rules, the target cigarette rolling unit will obtain the ventilation data of the target cigarette corresponding to the time the laser drilling device issues the target data acquisition request, based on the preset data delay acquisition rule in the preset data interaction rules. This ventilation data is then identified as target feedback data, so that the laser drilling device can update the target time parameter based on this target feedback data. Thus, when external interference causes the ventilation control to deviate from the stable state and target value, the target time parameter is automatically adjusted to allow the cigarette ventilation control to return to the stable state and near the target value after a short fluctuation, achieving rapid and stable adjustment of the cigarette ventilation.
