Description

Technical Field

[0001] The present invention relates to the field of signal processing technology, and in particular to a control strategy generation method, device, controller and medium for a lifting solenoid valve. Background Art

[0002] With the continuous development of production technology, cigarette making machines are widely used in the production process of tobacco. Therefore, how to ensure the health of cigarette making machines and improve their production efficiency is very important to the production process of tobacco.

[0003] In actual production, the lifting and lowering motion of the paddle wheel in a cigarette making machine is typically controlled by a solenoid valve and a pneumatic cylinder. When the machine starts, the paddle wheel solenoid valve is energized, and the paddle wheel mechanism is raised to the operating position by the cylinder. When the machine stops, the solenoid valve loses power, and the paddle wheel mechanism drops to the lower limit. Cigarette making machines typically need to remain in operation for extended periods of time to meet production requirements. Therefore, the paddle wheel solenoid valve must be continuously energized to ensure that the paddle wheel remains in the operating position. However, if the solenoid valve coil is energized for an extended period of time, heat is generated. Furthermore, the paddle wheel solenoid valve is often installed in a confined area with no heat dissipation, resulting in frequent damage due to coil burnout.

[0004] However, because the paddle wheel solenoid valve is installed behind the wall panel that holds the tobacco trimming unit, replacing it typically requires mechanical and electrical technicians to dismantle the entire trimming unit, a time-consuming repair process that reduces production efficiency. Therefore, extending the life of the paddle wheel solenoid valve, reducing its replacement frequency, and improving production efficiency are pressing challenges. Summary of the Invention

[0005] The present invention provides a control strategy generation method, device, controller and medium for a lifting solenoid valve, which can solve the problem of short service life of the impeller solenoid valve and thus low tobacco production efficiency.

[0030] Example 1

[0031] Figure 1 This is a flow chart of a method for generating a control strategy for a lifting solenoid valve provided in the first embodiment of the present invention. This embodiment is applicable to controlling the working time of the lifting solenoid valve of the paddle wheel of a cigarette making machine. The method can be executed by a control strategy generating device for the lifting solenoid valve. The control strategy generating device for the lifting solenoid valve can be implemented in the form of hardware and / or software. The control strategy generating device for the lifting solenoid valve can be configured in a target programmable controller. Figure 1 As shown, the method includes:

[0032] S110. Obtain an initial solenoid valve output signal set and a current working period corresponding to a target cigarette-making machine, and determine a target working mechanism corresponding to the target cigarette-making machine in a preset working mechanism set based on the current working period; wherein the target cigarette-making machine is a cigarette-making machine that has undergone gas path exchange processing.

[0033] Among them, the target cigarette-making machine may refer to a pre-selected cigarette-making machine that needs to control the impeller solenoid valve. For example, the target cigarette-making machine can be selected according to actual needs. In an embodiment of the present invention, the target cigarette-making machine may be any cigarette-making machine that has undergone an air path exchange process. The air path exchange process may refer to the operation of reversing the two air outlets of the solenoid valve that controls the action of the cigarette-making machine's impeller. Usually, there are two solenoid valves that control the action of the cigarette-making machine's impeller, namely the front impeller solenoid valve and the rear impeller solenoid valve, and each solenoid valve contains two air outlets for controlling the cylinder to move forward and backward. For example, if the working process of the solenoid valve without air path exchange process is: the cylinder moves forward when the power is on, and moves backward when the power is off, then the working process of the solenoid valve after the air path exchange process may be: the cylinder moves backward when the power is on, and moves forward when the power is off.

[0034] The solenoid valve output signal may refer to a signal generated based on the cigarette making machine's operating state for controlling the movement of the machine's paddle wheels. For example, the solenoid valve output signal may be the output signal of the front-pass paddle wheel rising solenoid valve that controls the movement of the front-pass paddle wheel, or the output signal of the back-pass paddle wheel rising solenoid valve that controls the movement of the back-pass paddle wheel. Typically, if the cigarette making machine is in the running state, the solenoid valve output signal is a high-level signal; if the cigarette making machine is in the stopped state, the solenoid valve output signal is a low-level signal. The initial solenoid valve output signal may refer to the solenoid valve output signal initially collected during a strategy generation process. The initial solenoid valve output signal set may refer to the set of initial solenoid valve output signals corresponding to the same collection time point for a target cigarette making machine. For example, the initial solenoid valve output signal set may include the output signal of the front-pass paddle wheel rising solenoid valve and the output signal of the back-pass paddle wheel rising solenoid valve corresponding to the same collection time point for the target cigarette making machine.

[0035] The current working period may refer to the working period corresponding to when the initial solenoid valve output signal set is obtained. In an optional embodiment, the current working period may include: a daytime working period or a nighttime working period. The daytime working period may refer to a production period set according to actual production needs. For example, the daytime working period may refer to a period from 7:00 a.m. on the same day to 1:00 a.m. on the next day. The nighttime working period may refer to a production suspension period set according to actual production needs. For example, the nighttime working period may refer to a period from 1:00 a.m. on the same day to 7:00 a.m. on the same day. The preset working mechanism may refer to a pre-set rule for defining the workflow of the current working period. In an embodiment of the present invention, the preset working mechanisms may be preliminarily divided according to the current working period, that is, the preset working mechanisms may be a working mechanism representing normal production and a working mechanism representing normal production suspension. The preset working mechanism set may refer to a set consisting of various preset working mechanisms. The target working mechanism may refer to a preset working mechanism in the preset working mechanism set that matches the target cigarette making machine.

[0036] S120: Perform process judgment on the initial solenoid valve output signal set based on the target working mechanism to determine the basic working process corresponding to the target cigarette making machine.

[0037] Among them, process judgment can refer to the operation of determining the current workflow of the target cigarette making machine according to the target working mechanism. The basic workflow can refer to the judgment result generated after the process judgment of the initial solenoid valve output signal set according to the target working mechanism. For example, if the target working mechanism is a working mechanism representing normal production, and the initial solenoid valve output signal set is a high-level signal, then the basic workflow can be that the cigarette making machine controls the front and rear track rising solenoid valves to be energized to control the impeller mechanism to rise. If the target working mechanism is a working mechanism representing normal production, and the initial solenoid valve output signal set is a low-level signal, then the basic workflow can be that the cigarette making machine controls the front and rear track rising solenoid valves to be de-energized to control the impeller mechanism to descend. If the target working mechanism is a working mechanism for normal shutdown operation, then the basic workflow can be that the cigarette making machine disconnects the compressed air.

[0038] S130 , performing control conversion on the initial solenoid valve output signal set based on the basic workflow and preset conversion rules to obtain a target control strategy corresponding to the target cigarette making machine.

[0039] The preset conversion rule may refer to a pre-set rule that defines the conversion process for the initial solenoid valve output signal. Exemplarily, the preset conversion rule may be a negation rule or a low-level rule. Typically, if the basic workflow involves the cigarette maker controlling the front and rear lane ascending solenoid valves to energize to control the paddle wheel mechanism's ascent, or if the cigarette maker controls the front and rear lane ascending solenoid valves to deenergize to control the paddle wheel mechanism's descent, the preset conversion rule may be a negation rule, i.e., a conversion rule between input and output signals determined based on the circuit principles of the target programmable controller. If the basic workflow involves the cigarette maker disconnecting the compressed air supply, the preset conversion rule may be a low-level rule, i.e., generating a low-level output signal regardless of whether the initial solenoid valve output signal set is high. Control conversion may refer to the operation of converting the initial solenoid valve output signal set to generate an output signal according to the preset conversion rule that matches the basic workflow. The target control strategy may refer to the signal generated after control conversion of the initial solenoid valve output signal set according to the preset conversion rule that matches the basic workflow. For example, if the basic workflow is for the cigarette maker to energize the front and rear lane ascending solenoid valves to control the paddle wheel mechanism to ascend, the generated target control strategy may be a low-level signal. If the basic workflow is for the cigarette maker to de-energize the front and rear lane ascending solenoid valves to control the paddle wheel mechanism to descend, the generated target control strategy may be a high-level signal. If the basic workflow is for the cigarette maker to disconnect the compressed air, the generated target control strategy may be a low-level signal.

[0040] The technical solution of the embodiment of the present invention determines the target working mechanism corresponding to the target cigarette-making machine in the preset working mechanism set through the current working period corresponding to the target cigarette-making machine that has undergone air path exchange processing. Afterwards, the process of the initial solenoid valve output signal set is judged based on the target working mechanism to determine the basic working process corresponding to the target cigarette-making machine. Finally, the initial solenoid valve output signal set is controlled and converted based on the basic working process and the preset conversion rules to obtain the target control strategy corresponding to the target cigarette-making machine. Due to the improvement of the working mode of the impeller solenoid valve and the air path of the impeller cylinder, the problem of the short service life of the impeller solenoid valve and the low tobacco production efficiency is solved, the service life of the impeller solenoid valve can be extended, the replacement frequency of the impeller solenoid valve can be reduced, and the production efficiency is improved.

[0041] Example 2

[0042] Figure 2This is a flow chart of a method for generating a control strategy for a lifting solenoid valve provided in the second embodiment of the present invention. This embodiment is refined based on the above embodiment. In this embodiment, the operation of obtaining the initial solenoid valve output signal set corresponding to the target cigarette making machine is specifically refined. Specifically, it may include: collecting the output signal of the front-pass paddle wheel lifting solenoid valve output module of the target cigarette making machine through the first input point of the target programmable controller as the first initial solenoid valve output signal; collecting the output signal of the rear-pass paddle wheel lifting solenoid valve output module of the target cigarette making machine through the second input point of the target programmable controller as the second initial solenoid valve output signal; summarizing and processing the first initial solenoid valve output signal and the second initial solenoid valve output signal as the initial solenoid valve output signal set corresponding to the target cigarette making machine. Figure 2 As shown, the method includes:

[0043] S210 , collecting an output signal of an output module of a front-end impeller lifting solenoid valve of a target cigarette making machine through a first input point of a target programmable controller, and using the signal as a first initial solenoid valve output signal.

[0044] Among them, the target programmable controller may refer to an electronic system for implementing pre-set digital calculation operations. Exemplarily, the target programmable controller may be any programmable logic controller (PLC). The first input point may refer to the first signal input point in the target programmable controller. Usually, it can be represented by the symbol I0.0. The front-end impeller rising solenoid valve output module may refer to a module on the target cigarette making machine for outputting the rising signal of the front-end impeller. In an embodiment of the present invention, the first input point of the target programmable controller is connected to the front-end impeller rising solenoid valve output module of the target cigarette making machine. The first initial solenoid valve output signal may refer to the signal outputted for the first time by the front-end impeller rising solenoid valve output module in a strategy generation process. Exemplarily, the first initial solenoid valve output signal may be the front-end impeller rising signal.

[0045] S220 , collecting the output signal of the rear-pass impeller ascending electromagnetic valve output module of the target cigarette making machine through the second input point of the target programmable controller as the second initial electromagnetic valve output signal.

[0046] Among them, the second input point may refer to the second signal input point in the target programmable controller. Usually, it can be represented by the symbol I0.1. The back-pass impeller rising solenoid valve output module may refer to the module on the target cigarette making machine for outputting the rising signal of the back-pass impeller. In an embodiment of the present invention, the second input point of the target programmable controller is connected to the back-pass impeller rising solenoid valve output module of the target cigarette making machine. The second initial solenoid valve output signal may refer to the signal output by the back-pass impeller rising solenoid valve output module for the first time in a strategy generation process. Exemplarily, the second initial solenoid valve output signal may be the back-pass impeller rising signal.

[0047] S230: Summarize and process the first initial solenoid valve output signal and the second initial solenoid valve output signal to form a set of initial solenoid valve output signals corresponding to a target cigarette-making machine.

[0048] Specifically, before implementing strategic control of the paddle wheel solenoid valve, the first input point of the target programmable controller can be used to collect the output signal of the target cigarette machine's front-end paddle wheel rising solenoid valve output module to obtain a first initial solenoid valve output signal. The second input point of the target programmable controller can also be used to collect the output signal of the target cigarette machine's rear-end paddle wheel rising solenoid valve output module to obtain a second initial solenoid valve output signal. Furthermore, the first and second initial solenoid valve output signals at the same collection time point are aggregated to obtain a set of initial solenoid valve output signals corresponding to the target cigarette machine. This provides an effective basis for subsequently generating a control strategy.

[0049] S240: Obtain the current working time point corresponding to the target cigarette-making machine, divide the current working time point into time periods based on a preset time period division rule, and determine the current working time period corresponding to the target cigarette-making machine.

[0050] The current working time point may refer to the time at which the initial solenoid valve output signal set is collected. The preset time period division rule may refer to a pre-set rule for defining the time period division process. For example, the preset time period division rule may classify the time period from 7:00 a.m. of the current day to 1:00 a.m. of the next day as the daytime working period, and the time period from 1:00 a.m. of the current day to 7:00 a.m. of the current day as the nighttime working period.

[0051] Specifically, after acquiring the initial solenoid valve output signal set corresponding to the target cigarette making machine, the signal acquisition moment at which the initial solenoid valve output signal set was acquired can be recorded as the current operating time point corresponding to the target cigarette making machine. Furthermore, the current operating time point is divided into time periods using a preset time period division rule. If the current operating time point falls within the preset daytime operating period, the daytime operating period is used as the current operating period; if the current operating time point falls within the preset nighttime operating period, the nighttime operating period is used as the current operating period. This allows the current operating period of the target cigarette making machine to be determined, providing an effective basis for subsequent operations.

[0052] S250. Determine a target working mechanism corresponding to the target cigarette-making machine in a preset working mechanism set based on the current working period; wherein the target cigarette-making machine is a cigarette-making machine that has undergone gas path exchange processing.

[0053] S260: Perform process judgment on the initial solenoid valve output signal set based on the target working mechanism to determine the basic working process corresponding to the target cigarette making machine.

[0054] In an optional embodiment, if the current working period is a nighttime working period, performing process judgment on the initial solenoid valve output signal set based on the target working mechanism to determine the basic working process corresponding to the target cigarette making machine includes:

[0055] Step a1: Obtain the current compressed air detection signal corresponding to the target cigarette making machine.

[0056] The compressed air detection signal may refer to a signal indicating whether compressed air is present in the cigarette making machine. Generally, if compressed air is present in the cigarette making machine, the compressed air detection signal may be a high-level signal. If compressed air is not present in the cigarette making machine, the compressed air detection signal may be a low-level signal. The current compressed air detection signal may refer to the compressed air detection signal corresponding to the target cigarette making machine during its current operating period.

[0057] In an optional embodiment, obtaining the current compressed air detection signal corresponding to the target cigarette making machine includes: collecting the output signal of the compressed air detection module of the target cigarette making machine through the third input point of the target programmable controller as the current compressed air detection signal corresponding to the target cigarette making machine.

[0058] The third input point may refer to the third signal input point of the target programmable controller. Typically, this is represented by the symbol I0.2. The compressed air detection module may refer to a module on the target cigarette-making machine that outputs a compressed air detection signal. In this embodiment of the present invention, the third input point of the target programmable controller is connected to the compressed air detection module of the target cigarette-making machine.

[0059] Step a2: performing signal judgment on the current compressed air detection signal based on the target working mechanism, and generating a signal judgment result corresponding to the current compressed air detection signal.

[0060] The signal determination result may refer to a determination result generated after performing a signal determination on the current compressed air detection signal based on the target working mechanism. For example, the signal determination result may be that the current compressed air detection signal is a low-level signal or a high-level signal.

[0061] Step a3: performing a process judgment on the initial solenoid valve output signal set based on the signal judgment result to determine the basic work flow corresponding to the target cigarette making machine.

[0062] Specifically, after determining the target operating mechanism corresponding to the target cigarette making machine from a set of preset operating mechanisms based on the current operating period, if the current operating period is nighttime, the third input point of the target programmable controller can first be used to collect the output signal of the compressed air detection module of the target cigarette making machine to obtain the current compressed air detection signal corresponding to the target cigarette making machine. Next, a signal judgment is performed on the current compressed air detection signal using the target operating mechanism to determine the signal judgment result corresponding to the current compressed air detection signal. Finally, if the signal judgment result indicates that the current compressed air detection signal is a low-level signal, the cigarette making machine is disconnected from compressed air as the basic operating process corresponding to the target cigarette making machine, regardless of whether the initial solenoid valve output signal set is a high-level signal. Therefore, even if the first and second input points of the target programmable controller collect a low-level signal from the output module, the output point of the target programmable controller will output a low-level signal to the front and rear lift solenoid valves, de-energizing the solenoid valves. Consequently, there is no compressed air in the cigarette making machine, and the impeller will not be lifted, thus preventing a collision.

[0063] It is worth noting that in an embodiment of the present invention, if the current working period is the daytime working period, the target working mechanism may include a working sub-mechanism representing normal production operation and a working sub-mechanism representing normal production shutdown. Then, based on the target working mechanism, a process judgment is performed on the initial solenoid valve output signal set to determine the basic workflow corresponding to the target cigarette-making machine. This may include: performing a process judgment on the initial solenoid valve output signal set based on each working sub-mechanism in the target working mechanism to generate a judgment result. If the judgment result is that the initial solenoid valve output signal set meets the working sub-mechanism representing normal production operation, the normal production operation process can be used as the basic workflow corresponding to the target cigarette-making machine. Similarly, if the judgment result is that the initial solenoid valve output signal set meets the working sub-mechanism representing normal production shutdown, the normal production shutdown process can be used as the basic workflow corresponding to the target cigarette-making machine.

[0064] S270: Based on the basic workflow and preset conversion rules, control conversion is performed on the initial electromagnetic valve output signal set to obtain a target control strategy corresponding to the target cigarette making machine.

[0065] Specifically, after obtaining the basic workflow corresponding to the target cigarette-making machine, the corresponding target conversion rule can be determined from the preset conversion rules according to the basic workflow. For example, if the basic workflow involves the cigarette-making machine energizing the front and rear track ascending solenoid valves to control the paddle wheel mechanism to ascend, or deenergizing the front and rear track ascending solenoid valves to control the paddle wheel mechanism to descend, the negation rule in the preset conversion rules can be used as the target conversion rule. Similarly, if the basic workflow involves the cigarette-making machine disconnecting the compressed air, the low-level rule in the preset conversion rules can be used as the target conversion rule.

[0066] Therefore, when the basic workflow is for the cigarette maker to control the front and rear lane ascending solenoid valves to be energized to control the paddle wheel mechanism to rise, the initial solenoid valve output signal set can be inverted to obtain a low-level output signal. When the basic workflow is for the cigarette maker to control the front and rear lane ascending solenoid valves to be deenergized to control the paddle wheel mechanism to descend, the initial solenoid valve output signal set can be inverted to obtain a high-level output signal. This causes the solenoid valve operating state to be reversed, reducing the solenoid valve operating time and reducing thermal damage failures. Furthermore, if the basic workflow is for the cigarette maker to disconnect the compressed air, a low-level signal is output regardless of whether the initial solenoid valve output signal set is high, ensuring that the solenoid valve is in a long-term power-off state.

[0067] S280: Send the target control strategy to the target cigarette-making machine, so that the target cigarette-making machine implements corresponding functions according to the target control strategy.

[0068] Specifically, after generating the target control strategy, the target control strategy can be sent to the target cigarette making machine via the output point of the target programmable controller. For example, in an embodiment of the present invention, the first output point of the target programmable controller can be connected to the front-end paddle wheel lift solenoid valve of the target cigarette making machine, and the second output point of the target programmable controller can be connected to the back-end paddle wheel lift solenoid valve of the target cigarette making machine. Thus, the target control strategy can be sent to the front-end paddle wheel lift solenoid valve of the target cigarette making machine via the first output point of the target programmable controller, and to the back-end paddle wheel lift solenoid valve of the target cigarette making machine via the second output point of the target programmable controller, so that the front and back solenoid valves execute corresponding actions according to the target control strategy, completing the control process of the solenoid valves.

[0069] In an optional embodiment, if the current working period is a night working period, after sending the target control strategy to the target cigarette making machine so that the target cigarette making machine implements the corresponding function according to the target control strategy, it also includes: obtaining the sending time of the target control strategy, and accumulating and summarizing the sending time based on a preset timing mechanism to obtain the accumulated time point corresponding to the sending time; performing a threshold judgment on the accumulated time point based on a preset time threshold, and if the accumulated time point meets the preset time threshold, generating a state recovery strategy based on a preset state recovery mechanism.

[0070] The "sending time" may refer to the time at which the target programmable controller sends the target control strategy to the target cigarette making machine. The "preset timing mechanism" may refer to a pre-set time accumulation rule. For example, the pre-set timing mechanism may accumulate time every second. The "accumulated time point" may refer to the accumulated time from the sending time to the current time point. For example, if the sending time is 8:00 PM and the current time point is 9:00 PM, the accumulated time point may be one hour. Typically, the accumulated time point can be determined by the target programmable controller's internal timer. The "preset time threshold" may refer to a pre-set value used to evaluate the accumulated time point. For example, the "preset time threshold" may be determined based on the rule for dividing the daytime working period and the nighttime working period. Specifically, for example, if the daytime working period is from 7:00 AM to 1:00 AM the following day, and the nighttime working period is from 1:00 AM to 7:00 AM the following day, the "preset time threshold" may be six hours. The "preset state recovery mechanism" may refer to a pre-set mechanism for restoring the output signal. For example, the "preset state recovery mechanism" may restore the output signal to a high level state. The state restoration strategy may refer to an output level signal generated according to a preset state restoration mechanism.

[0071] Specifically, if the current operating period is nighttime, after the target control strategy is transmitted to the target cigarette-making machine, causing it to implement the corresponding functions according to the target control strategy, the target control strategy transmission time can be determined, and the transmission times can be accumulated according to a preset timing mechanism to obtain a cumulative time point. Furthermore, a threshold judgment is performed on the cumulative time point using a preset time threshold. If the cumulative time point meets the preset time threshold, a state recovery strategy is generated based on a preset state recovery mechanism. This ensures that the impeller does not rise when the compressed air is turned on during daytime operating hours, avoiding collisions.

[0072] The technical solution of the embodiment of the present invention collects the output signal of the target cigarette making machine's front-end paddle wheel rising solenoid valve output module through the first input point of the target programmable controller, which is used as the first initial solenoid valve output signal. The output signal of the target cigarette making machine's rear-end paddle wheel rising solenoid valve output module is collected through the second input point of the target programmable controller, which is used as the second initial solenoid valve output signal. The first initial solenoid valve output signal and the second initial solenoid valve output signal are aggregated and processed to form the initial solenoid valve output signal set corresponding to the target cigarette making machine. Furthermore, the current operating time point corresponding to the target cigarette making machine is obtained, and the current operating time point is divided into time periods based on preset time period division rules to determine the current operating time period corresponding to the target cigarette making machine. Furthermore, based on the current operating time period, the target operating mechanism corresponding to the target cigarette making machine is determined from the preset operating mechanism set. Based on the target operating mechanism, a process judgment is performed on the initial solenoid valve output signal set to determine the basic workflow corresponding to the target cigarette making machine. Finally, based on the basic workflow and pre-set conversion rules, the initial solenoid valve output signal set is controlled and converted to obtain the target control strategy corresponding to the target cigarette making machine. This target control strategy is then transmitted to the target cigarette making machine, enabling the target cigarette making machine to implement the corresponding function according to the target control strategy. By improving the working mode of the paddle wheel solenoid valve and the air path of the paddle wheel cylinder, the problem of the paddle wheel solenoid valve's short service life, which leads to low tobacco production efficiency, is solved. This can extend the paddle wheel solenoid valve's service life, reduce the frequency of paddle wheel solenoid valve replacement, and improve production efficiency.

[0073] Based on the above embodiments, an alternative method for generating a control strategy for a lifting solenoid valve provided by an embodiment of the present invention may have the following process: First, an initial solenoid valve output signal set and the current operating period corresponding to a target cigarette making machine are obtained. If the current operating period is daytime, the operating mechanism representing normal production is determined as the target operating mechanism corresponding to the target cigarette making machine, and the target operating mechanism is used to perform a process judgment on the initial solenoid valve output signal set. If the initial solenoid valve output signal set is a high-level signal, it can be determined that the target cigarette making machine meets the operating sub-mechanism representing normal production operation within the target operating mechanism. The basic workflow corresponding to the target cigarette making machine can be a normal production operation workflow, i.e., the cigarette making machine controls the front and rear lifting solenoid valves to energize and control the paddle wheel mechanism to rise. Therefore, the negation rule can be determined as a preset conversion rule, and the preset conversion rule can be used to control the initial solenoid valve output signal set to obtain the target control strategy corresponding to the target cigarette making machine, i.e., a low-level signal. As a result, when the cigarette making machine is in production for an extended period, the paddle wheel solenoid valve remains de-energized. This allows the paddle wheel solenoid valve to be de-energized and inoperative when the cigarette making machine is started, while the cylinder continues to rise and the paddle wheel remains in its operating position.

[0074] If the initial solenoid valve output signal set is a low-level signal, the target cigarette making machine can be determined to comply with the target operating mechanism's sub-mechanism representing a normal production shutdown. The target cigarette making machine's corresponding basic workflow can be a normal production shutdown process, where the machine de-energizes the front and rear ascending solenoid valves, thereby lowering the paddle wheel mechanism. Therefore, the negation rule can be determined as a preset conversion rule, and the preset conversion rule can be used to control and convert the initial solenoid valve output signal set, resulting in a target control strategy corresponding to the target cigarette making machine, namely, a high-level signal. Thus, when the cigarette making machine is briefly shut down, the paddle wheel solenoid valve remains energized for a short period of time. This allows the paddle wheel solenoid valve to energize, the cylinder to descend, and the paddle wheel to its lower limit position.

[0075] If the current working period is the nighttime working period, the working mechanism representing normal production suspension is set as the target working mechanism for the target cigarette making machine. Subsequently, the current compressed air detection signal corresponding to the target cigarette making machine is obtained and a signal judgment is performed on the current compressed air detection signal using the target working mechanism to generate a signal judgment result corresponding to the current compressed air detection signal. If the signal judgment result indicates that the current compressed air detection signal is a low-level signal, the cigarette making machine is disconnected from the compressed air as the basic working process for the target cigarette making machine, regardless of whether the initial solenoid valve output signal set is a high-level signal. Furthermore, a low-level setting rule can be used as a preset conversion rule, and the preset conversion rule can be used to control the initial solenoid valve output signal set to convert and output the target control strategy, i.e., a low-level signal. Furthermore, after the target control strategy is transmitted to the target cigarette making machine so that the target cigarette making machine implements the corresponding function according to the target control strategy, an internal timer is started to accumulate the target control strategy transmission times to obtain a cumulative time point. A threshold judgment is then performed on the cumulative time point based on a preset time threshold. If the cumulative time point meets the preset time threshold, a state recovery strategy, i.e., a high-level output signal, is generated based on a preset state recovery mechanism. Therefore, when the cigarette making machine is stopped for a long time, the positive pressure will also be turned off. When the programmable controller does not collect the positive pressure signal, it will not output the power signal of the impeller solenoid valve, which can avoid the situation where the impeller solenoid valve is powered for a long time when the cigarette making machine is stopped for a long time.
