When the cigarette packet packaging line is determined to be in a normal operation state by combining the cigarette packet detection signals collected by the buffer cigarette packet depletion detection device and the preset transportation data, the energization state of the relay can be used to make the buffer cigarette packet depletion detection device in a shutdown state, so as to effectively avoid the safety hazards caused by manual shielding treatment by combining the automatic control mode of the buffer cigarette packet depletion detection device, and the overall packaging efficiency and the normal operation of the buffer cigarette packet depletion detection device can also be ensured.

Description

Technical Field

[0001] This application belongs to the field of tobacco packaging production technology, and specifically relates to a control method and system for a buffer cigarette pack depletion detection device. Background Technology

[0002] In the actual production process of cigarette factories, buffer packs are an important concept. They typically refer to a temporary storage area on the production line used to temporarily store cigarette packs that have completed part of the process but have not yet entered the next process. The main purpose of this buffer is to balance the work rhythm of each section of the production line, preventing downtime or production bottlenecks caused by asynchronous speeds in one part.

[0003] As a monitoring mechanism, the buffer pack depletion detection device can be used to monitor the quantity or status of packs in the buffer zone in real time. When the production line is running normally, the buffer zone should maintain a certain number of packs to maintain the continuity of production. If, for some reason, such as upstream production being too slow, downstream consumption being too fast, or other unforeseen problems, the number of packs in the buffer zone drops below the preset safety threshold or is even depleted, this detection device will issue an alarm, prompting relevant personnel to take corresponding measures, such as adjusting the production cycle, troubleshooting, or increasing the production line load, thereby avoiding production line shutdown, reduced production efficiency, or quality problems.

[0004] Currently, when using the buffer cigarette pack exhaustion detection device on the GDX1 and GDX2 models of small box transparent paper packaging machines in the packaging unit, the tobacco packaging production line needs to frequently start production or empty the equipment. In order to prevent the buffer cigarette pack exhaustion detection device from failing to reset and start due to the absence of cigarette packs in the buffer area, the usual practice is to manually cover the buffer cigarette pack exhaustion detection device with waste materials. This is not only an improper operation that can easily bring certain safety hazards to the packaging equipment, but it can also easily cause missing packs, thereby affecting the overall packaging efficiency. Summary of the Invention

[0005] This application addresses the aforementioned technical problems of manually obscuring the depletion detection device of the cushioned cigarette pack using waste materials. These problems are not only due to improper operation and potential safety hazards to the packaging equipment, but also because they can easily lead to missing packs, thus affecting overall packaging efficiency. Therefore, this application proposes a control method and system for the cushioned cigarette pack depletion detection device, the technical solution of which is as follows:

[0006] In a first aspect, embodiments of this application provide a control method for a buffer cigarette pack depletion detection device, comprising:

[0007] When the tobacco packaging production line is in operation, at least two cigarette pack packaging data are acquired within a preset time period, and the first deviation is calculated based on all cigarette pack packaging data and preset transportation data.

[0008] When the first deviation is detected to exceed the preset deviation threshold, a control signal is output to the circuit where the relay is located, so that the normally open contact corresponding to the relay and the circuit where the buffer cigarette pack depletion detection device is located are in the conducting state.

[0009] The detection signal of the cigarette pack collected by the buffer cigarette pack depletion detection device is processed, and the second deviation is determined based on the processing result and the preset transportation data.

[0010] When the second deviation is detected to be less than the preset deviation threshold, the control signal output to the circuit where the relay is located is stopped, so that the normally open contact corresponding to the relay and the circuit where the buffer cigarette pack depletion detection device is located are switched from the conducting state to the disconnected state.

[0011] In one alternative to the first aspect, a first deviation is calculated based on all cigarette pack packaging data and preset transportation data, including:

[0012] The average value of all cigarette pack packaging data is calculated and processed to obtain the average packaging data.

[0013] When the difference between the average packaging data and any cigarette pack packaging data is detected to be within a preset difference range, the average packaging data is transformed based on the preset transportation data.

[0014] The first deviation is obtained based on the difference between the average value of the processed packaging data and the preset transportation data.

[0015] In another alternative to the first aspect, the cigarette pack detection signal includes at least two sub-cigarette pack detection signals;

[0016] The processing of the cigarette pack detection signal collected by the buffer cigarette pack depletion detection device includes:

[0017] Based on the detection signals of all sub-batch cigarette packs collected by the buffer cigarette pack depletion detection device and the collection time corresponding to each sub-batch cigarette pack detection signal, the cigarette pack fitting curve is obtained;

[0018] Select at least two fitting points from the cigarette pack fitting curve, and calculate the cigarette pack buffer data based on all fitting points;

[0019] When the cigarette pack buffer data is detected to be within the preset buffer zone, the cigarette pack buffer data is transformed based on the preset transportation data, and the processed cigarette pack buffer data is used as the processing result.

[0020] In another alternative to the first aspect, after calculating the pack buffer data based on all fitted points, it further includes:

[0021] When it is detected that the cigarette pack buffer data is not within the preset buffer zone, the weight of the remaining cigarette pack in the cigarette pack buffer area is collected based on the weight detection device;

[0022] A warning signal is issued when the ratio between the weight of the remaining cigarette pack and the weight of the standard cigarette pack corresponding to the buffer area of ​​the cigarette pack is lower than a preset ratio threshold.

[0023] In another alternative to the first aspect, a second deviation is determined based on the processing results and preset transportation data, including:

[0024] The mean of the processed packaging data and the buffer data of the processed cigarette packs are integrated to obtain the integrated cigarette pack data;

[0025] The second deviation is obtained based on the difference between the integrated data of the cigarette packs and the preset transportation data.

[0026] In another alternative to the first aspect, determining the second deviation based on the processing results and preset transportation data further includes:

[0027] The mean of the processed packaging data and the buffer data of the processed cigarette packs are integrated to obtain the integrated cigarette pack data;

[0028] Obtain sorting data from at least two cigarette packs, and calculate the average sorting data based on preset transportation data and all cigarette pack sorting data.

[0029] The second deviation was determined based on the integrated data of cigarette packs, the average sorting data, and the preset transportation data.

[0030] In another alternative to the first aspect, a second deviation is determined based on the integrated tobacco package data, the average sorting data, and preset transportation data, including:

[0031] The difference between the integrated data of cigarette packs and the preset transportation data is taken as the first difference, and the difference between the average sorting data and the preset transportation data is taken as the second difference.

[0032] The first difference and the second difference are weighted and summed based on preset weights to obtain the second deviation.

[0033] Secondly, embodiments of this application provide a control system for a buffer cigarette pack depletion detection device, comprising:

[0034] The first processing module is used to acquire at least two cigarette pack packaging data within a preset time period when the tobacco packaging production line is in operation, and to calculate the first deviation based on all cigarette pack packaging data and preset transportation data.

[0035] The second processing module is used to output a control signal to the circuit where the relay is located when the first deviation is detected to exceed the preset deviation threshold, so that the normally open contact corresponding to the relay and the circuit where the buffer cigarette pack depletion detection device is located are in the conducting state.

[0036] The third processing module is used to process the cigarette pack detection signal collected by the buffer cigarette pack depletion detection device, and determine the second deviation based on the processing results and preset transportation data.

[0037] The fourth processing module is used to stop outputting control signals to the circuit where the relay is located when the detected second deviation does not exceed the preset deviation threshold, so that the normally open contact corresponding to the relay and the circuit where the buffer cigarette pack depletion detection device is located are switched from the conducting state to the disconnected state.

[0038] Thirdly, embodiments of this application also provide a control system for a buffer cigarette pack depletion detection device, including a processor and a memory;

[0039] The processor is connected to the memory;

[0040] Memory, used to store executable program code;

[0041] The processor runs a program corresponding to the executable program code by reading the executable program code stored in the memory, so as to implement the control method for the buffer cigarette pack depletion detection device provided by the first aspect or any implementation of the first aspect of the embodiments of this application.

[0042] Fourthly, embodiments of this application provide a computer storage medium storing a computer program, which includes program instructions. When executed by a processor, the program instructions can implement the control method for the buffer cigarette pack depletion detection device provided in the first aspect or any implementation of the first aspect of this application.

[0043] In this embodiment, when controlling the buffer cigarette pack depletion detection device of the tobacco packaging production line, when the tobacco packaging production line is in operation, at least two cigarette pack packaging data are acquired within a preset time period, and a first deviation is calculated based on all cigarette pack packaging data and preset transportation data; when the first deviation is detected to exceed a preset deviation threshold, a control signal is output to the circuit where the relay is located, so that the normally open contact corresponding to the relay and the circuit where the buffer cigarette pack depletion detection device is located are in a conducting state; the cigarette pack detection signal collected by the buffer cigarette pack depletion detection device is processed, and a second deviation is determined based on the processing result and preset transportation data; when the second deviation is detected not to exceed the preset deviation threshold, the control signal is stopped from being output to the circuit where the relay is located, so that the normally open contact corresponding to the relay and the circuit where the buffer cigarette pack depletion detection device is located are switched from a conducting state to a disconnected state. By combining tobacco pack packaging data from the tobacco packaging production line with preset transportation data, when it is determined that the number of tobacco packs in the buffer area is decreasing, the relay can be energized to keep the buffer tobacco pack depletion detection device in normal operation. Alternatively, by combining the tobacco pack detection signal collected by the buffer tobacco pack depletion detection device with preset transportation data, when it is determined that the tobacco packaging production line is in normal operation, the relay can be energized to shut down the buffer tobacco pack depletion detection device. This automatic control method effectively avoids the safety hazards caused by manual obstruction of the buffer tobacco pack depletion detection device, and also ensures overall packaging efficiency and the normal operation of the buffer tobacco pack depletion detection device.

[0051] Please see Figure 1 , Figure 1 This paper presents an overall flowchart of a control method for a buffer cigarette pack depletion detection device according to an embodiment of this application.

[0052] like Figure 1 As shown, the control method for the buffer cigarette pack depletion detection device may include at least the following steps:

[0053] Step 102: When the tobacco packaging production line is in operation, acquire at least two cigarette pack packaging data within a preset time period, and calculate the first deviation based on all cigarette pack packaging data and preset transportation data.

[0054] In the embodiments of this application, the control method for the buffer cigarette pack exhaustion detection device can be applied to, but is not limited to, a production line terminal. The production line terminal can change the on / off state of the circuit formed by the normally open contact corresponding to the relay and the buffer cigarette pack exhaustion detection device corresponding to the tobacco packaging production line by outputting different control signals to the relay, thereby realizing automatic control of the buffer cigarette pack exhaustion detection device. The buffer pack depletion detection device in the tobacco packaging production line involved in this application embodiment can be understood as a conventional monitoring mechanism device in the tobacco packaging production line (such as, but not limited to, photoelectric sensing devices, weight sensing devices, or image recognition devices). It is usually used to monitor the number of remaining cigarette packs in the buffer area. When the tobacco packaging production line experiences problems such as slow upstream production or rapid downstream consumption, it will automatically replenish the cigarette packs in the buffer area to ensure the normal operation of the overall production line. The buffer pack depletion detection device can issue an alarm when it detects that the number of remaining cigarette packs in the buffer area has been depleted, so as to prompt relevant personnel to take corresponding measures, such as adjusting the production cycle, troubleshooting, or increasing the production line load, thereby avoiding production line shutdown, reduced production efficiency, or quality problems. However, it may also fail to reset and restart when there are no cigarette packs in the buffer area, that is, the normal operation of the buffer pack depletion detection device cannot be guaranteed when the number of remaining cigarette packs in the buffer area has been depleted. It should be noted that the application process of the buffer cigarette pack depletion detection device and the application process of cigarette pack replenishment in the buffer area of ​​the cigarette pack involved in the embodiments of this application are technical means well known in tobacco packaging production lines, and will not be described in detail here.

[0055] Understandably, in the actual production process of a tobacco packaging production line, the production line terminal, by combining the tobacco pack packaging data and preset transportation data, can determine when the number of tobacco packs in the buffer area decreases. In this case, the relay can be energized to keep the buffer tobacco pack depletion detection device in normal operation. Conversely, by combining the tobacco pack detection signal collected by the buffer tobacco pack depletion detection device with preset transportation data, when the tobacco packaging production line is determined to be in normal operation, the relay can be energized to shut down the buffer tobacco pack depletion detection device. This automatic control of the buffer tobacco pack depletion detection device effectively avoids the safety hazards caused by manual obstruction, while also ensuring overall packaging efficiency and the normal operation of the buffer tobacco pack depletion detection device.

[0056] Specifically, when controlling the buffer pack depletion detection device in a tobacco packaging production line, the production line terminal can, but is not limited to, determine whether the tobacco packaging production line is in operation by detecting whether each process on the tobacco packaging production line has started normally (e.g., determining whether each process is connected to power). It is understood that when the tobacco packaging production line is determined to be in operation, the production line terminal can control the detection device installed on the packaging process to collect multiple pack packaging data within a preset time period. This pack packaging data can be understood as the time or speed required to package one or more packs, with each pack packaging data corresponding to the same number of packs. The detection device can then send the collected pack packaging data to the production line terminal, allowing the production line terminal to calculate a first deviation—indicating whether the tobacco packaging production line is experiencing excessively slow production—based on the multiple pack packaging data and preset transportation data. Here, the detection device installed on the packaging process can, but is not limited to, image recognition devices or related technologies well-known in the art, to obtain the corresponding pack packaging data by performing image recognition processing on multiple sets of captured images.

[0057] It is understood that the preset transportation data may be determined based on the historical transmission speed of the conveyor belt used to transport cigarette packs. For example, it can be understood as the number of cigarette packs transported within a specified time period based on the historical transmission speed. The specified time period may be 10 minutes, 20 minutes, or 30 minutes, and is not limited to this.

[0058] As an optional embodiment of this application, a first deviation is calculated based on all cigarette pack packaging data and preset transportation data, including:

[0059] The average value of all cigarette pack packaging data is calculated and processed to obtain the average packaging data.

[0060] When the difference between the average packaging data and any cigarette pack packaging data is detected to be within a preset difference range, the average packaging data is transformed based on the preset transportation data.

[0061] The first deviation is obtained based on the difference between the average of the processed packaging data and the preset transportation data.

[0062] Specifically, when calculating the first deviation used to characterize whether the tobacco packaging production line has slow packaging process, the production line terminal can integrate all cigarette pack packaging data. For example, when each cigarette pack packaging data corresponds to multiple cigarette packs, the time or speed required for packaging a single cigarette pack in each cigarette pack packaging data can be calculated first. Then, by averaging the time or speed required for packaging a single cigarette pack corresponding to all cigarette pack packaging data, the average time or speed required for packaging a single cigarette pack can be obtained.

[0063] Next, after obtaining the average time or speed required for packaging a single cigarette pack, the production line terminal can also use this average time or speed to determine whether there are any abnormal cigarette pack packaging data in all cigarette pack packaging data. That is, it can determine whether the difference between the average time or speed required for a single cigarette pack packaging and the average time or speed required for any other cigarette pack packaging data falls within a preset difference range. Understandably, when any difference is detected to be within the preset difference range, it indicates that there are no abnormalities in all cigarette pack packaging data. In other words, the calculated average time or speed required for a single cigarette pack packaging has high reliability. Therefore, based on preset transportation data, the average time or speed required for a single cigarette pack packaging can be converted for a more intuitive and faster comparison with the preset transportation data and the average time or speed required for a single cigarette pack packaging. Here, the preset transportation data is represented as the number of cigarette packs transported within a specified time period. The average packaging data is the average time required to package a single cigarette pack, as mentioned above. The ratio between the specified time period and the average time required to package a single cigarette pack can be used as the average of the processed packaging data, which is the number of cigarette packs packaged corresponding to the packaging process within the specified time period.

[0064] Next, after obtaining the average value of the processed packaging data, the production line terminal can calculate the difference between this average value and preset transportation data to obtain a first deviation characterizing whether the tobacco packaging production line is experiencing slow packaging process production. Here, when the first deviation exceeds a preset deviation threshold, it indicates a significant difference between the packaging process production efficiency and the cigarette pack transportation efficiency, posing a risk of slow packaging process production. When the first deviation does not exceed the preset deviation threshold, it indicates that the packaging process production efficiency is close to the cigarette pack transportation efficiency, allowing, but not limited to, transferring excess cigarette packs to a cigarette pack buffer area to ensure the normal operation of the tobacco packaging production line.

[0065] Step 104: When the first deviation is detected to exceed the preset deviation threshold, a control signal is output to the circuit where the relay is located, so that the normally open contact corresponding to the relay and the circuit where the buffer cigarette pack depletion detection device is located are in the conducting state.

[0066] Specifically, after calculating the first deviation used to characterize whether the tobacco packaging production line is experiencing slow production in the packaging process, when the first deviation is detected to exceed a preset deviation threshold, it indicates that the packaging process is slow. Then, the production line terminal can send a cigarette pack replenishment request to the tobacco packaging production line to automatically replenish the cigarette packs in the cigarette pack buffer area to the corresponding position. It can also output a high-level control signal to the circuit where the relay is located, so that the normally open contact corresponding to the relay and the circuit where the buffer cigarette pack depletion detection device is located are in a conducting state, so that the buffer cigarette pack depletion detection device is in a normal operating state (since there are cigarette packs in the current cigarette pack buffer area, it can be reset and powered on normally). The buffer cigarette pack depletion detection device monitors the number of remaining cigarette packs in the cigarette pack buffer area in real time. Here, when the circuit containing the relay does not receive a high-level control signal from the production line terminal, the normally open contact is in an open state without receiving any excitation. That is, the normally open contact and the circuit containing the buffer cigarette pack depletion detection device are in an open state. Therefore, the buffer cigarette pack depletion detection device cannot monitor the number of remaining cigarette packs in the cigarette pack buffer area, and can effectively control the energy consumption of the tobacco packaging production line.

[0067] Step 106: Process the cigarette pack detection signal collected by the buffer cigarette pack depletion detection device, and determine the second deviation based on the processing results and preset transportation data.

[0068] Specifically, after the buffer pack depletion detection device monitors the number of remaining cigarette packs in the buffer area in real time, the production line terminal can also acquire multiple sub-pack detection signals collected by the buffer pack depletion detection device at preset time intervals. Each sub-pack detection signal can be understood as the number of remaining cigarette packs monitored within the same time interval, and each sub-pack detection signal can be analyzed and processed by the buffer pack depletion detection device (or it can be obtained by the production line terminal through image recognition processing based on multiple sets of images collected by the buffer pack depletion detection device, and is not limited to this). Based on all sub-pack detection signals and the acquisition time corresponding to each sub-pack detection signal, a remaining cigarette pack quantity-time variation curve, i.e., a pack fitting curve, is fitted. It can be understood that this remaining cigarette pack quantity-time variation curve can more intuitively and accurately reflect the changing trend of the number of remaining cigarette packs in the buffer area over time, facilitating subsequent judgment on whether the remaining cigarette packs in the buffer area are about to be depleted.

[0069] Furthermore, after generating the cigarette pack fitting curve, the production line terminal can randomly select at least two fitting points from the cigarette pack fitting curve. The x-coordinate of each fitting point can be, but is not limited to, a certain moment in the cigarette pack fitting curve, and the y-coordinate of each fitting point can be, but is not limited to, the number of remaining cigarette packs in the cigarette pack fitting curve corresponding to the corresponding moment. By calculating the slope of the coordinates of any two adjacent fitting points, the average of all slopes is used as the cigarette pack buffer data, that is, the time required to reduce a single cigarette pack within the cigarette pack buffer area.

[0070] Furthermore, after calculating the cigarette pack buffer data, the production line terminal can also determine whether the cigarette pack buffer data is abnormal, for example, but not limited to determining whether the cigarette pack buffer data is within a preset buffer range. It is understood that when the cigarette pack buffer data is detected to be within a preset buffer range, it indicates that the time required to reduce a single cigarette pack within the cigarette pack buffer range is within the normal range. Therefore, the cigarette pack buffer data can be converted based on preset transportation data to facilitate a more intuitive and rapid judgment of whether the tobacco packaging production line is in a normal state. Here, the preset transportation data is represented by the number of cigarette packs transported within a specified time period, and the cigarette pack buffer data is the time required to reduce a single cigarette pack within the cigarette pack buffer area. For example, the ratio between the specified time period and the time required to reduce a single cigarette pack within the cigarette pack buffer area can be used as the processed cigarette pack buffer data, that is, the number of cigarette packs reduced within the cigarette pack buffer area within the specified time period.

[0071] Furthermore, after obtaining the processed cigarette pack buffer data, due to the aforementioned slow production speed in the packaging process, the tobacco packaging production line will automatically replenish the cigarette packs in the buffer area to the corresponding positions in order to ensure normal operation. At this time, the production line terminal can also use the processed cigarette pack buffer data as the processing result of the cigarette pack detection signal, and combine it with the preset transportation data to obtain a second deviation to characterize whether the tobacco packaging production line is operating normally.

[0072] As another optional embodiment of this application, after calculating the pack buffer data based on all fitted points, the method further includes:

[0073] When it is detected that the cigarette pack buffer data is not within the preset buffer zone, the weight of the remaining cigarette pack in the cigarette pack buffer area is collected based on the weight detection device;

[0074] A warning signal is issued when the ratio between the weight of the remaining cigarette pack and the weight of the standard cigarette pack corresponding to the buffer area of ​​the cigarette pack is lower than a preset ratio threshold.

[0075] Specifically, after calculating the cigarette pack buffer data, if it is detected that the data is not within the preset buffer zone, it indicates that the time required to reduce a single cigarette pack within the buffer zone is too fast. This could mean that the remaining cigarette packs in the buffer zone are rapidly depleted. In this case, the production line terminal can control a weight detection device to monitor the weight of the remaining cigarette packs in the current buffer zone to determine if there is any anomaly. Here, the weight detection device can be, but is not limited to, a weight sensor. It can be installed within the buffer zone to monitor the weight of the remaining cigarette packs, and is not limited to this.

[0076] Understandably, when the ratio between the weight of the remaining cigarette packs and the weight of the standard cigarette packs corresponding to the cigarette pack buffer area is lower than a preset ratio threshold, it indicates that there is a risk that the number of remaining cigarette packs in the current cigarette pack buffer area will be quickly depleted. This can then issue an early warning signal to the relevant staff so that remedial and investigation measures can be taken in a timely manner.

[0077] Of course, after generating the cigarette pack fitting curve in this embodiment, the production line terminal can also, but is not limited to, estimate the time required for the remaining cigarette packs in the cigarette pack buffer area to be exhausted based on the trend of the number of cigarette packs changing over time in the cigarette pack fitting curve. The time required for exhaustion can be used to determine whether to issue a warning signal to the relevant staff. It can also effectively prevent the buffer cigarette pack exhaustion detection device from failing to reset and start up during the detection process due to the absence of cigarette packs in the cigarette pack buffer area, which means it cannot be in normal operation afterward.

[0078] As another optional embodiment of this application, determining the second deviation based on the processing result and preset transportation data includes:

[0079] The mean of the processed packaging data and the buffer data of the processed cigarette packs are integrated to obtain the integrated cigarette pack data;

[0080] The second deviation is obtained based on the difference between the integrated data of the cigarette packs and the preset transportation data.

[0081] Specifically, when obtaining the second deviation used to characterize whether the tobacco packaging production line is operating normally, the production line terminal can also, but is not limited to, integrate the processed average packaging data and the processed cigarette pack buffer data. This results in the cigarette pack data jointly provided to the next process by the packaging process and the cigarette pack buffer area of ​​the tobacco packaging production line. Here, taking the processed average packaging data as the number of packaged cigarette packs corresponding to the packaging process within a specified time period, and the processed cigarette pack buffer data as the number of cigarette packs reduced in the cigarette pack buffer area within a specified time period, as an example, the integrated cigarette pack data can be the sum of the number of packaged cigarette packs corresponding to the packaging process within a specified time period and the number of cigarette packs reduced in the cigarette pack buffer area.

[0082] Next, after obtaining the integrated tobacco package data, the production line terminal can calculate the difference between this integrated data and the preset transportation data. This involves comparing the tobacco package data jointly provided to the next process by the packaging process and the tobacco package buffer area with the actual transported tobacco package data, and using the difference as the second deviation. Understandably, when the second deviation exceeds the preset deviation threshold, it indicates a significant difference between the production efficiency of the packaging process and the tobacco package buffer area and the transportation efficiency of the tobacco packages, meaning the tobacco packaging production line is not yet operating normally. When the second deviation does not exceed the preset deviation threshold, it indicates that the production efficiency of the packaging process and the tobacco package buffer area is close to the transportation efficiency of the tobacco packages. Therefore, the tobacco packaging production line can, but is not limited to, automatically adjust the number of tobacco packages replenished in the buffer area to maintain the normal operation of the tobacco packaging production line.

[0083] As another optional embodiment of this application, determining the second deviation based on the processing result and the preset transportation data further includes:

[0084] The average value of the processed packaging data and the buffer data of the cigarette pack are integrated to obtain integrated cigarette pack data;

[0085] Obtain at least two cigarette pack sorting data, and obtain the average sorting data based on the preset transportation data and all the cigarette pack sorting data;

[0086] The second deviation is determined based on the integrated data of the cigarette packs, the average value of the sorting data, and the preset transportation data.

[0087] Specifically, in addition to comparing the tobacco package data provided to the next process by the packaging process and the tobacco package buffer area with the actual transported tobacco package data, it is also possible, but not limited to, comparing the tobacco package data provided to the next process by the packaging process and the tobacco package buffer area with the tobacco package data corresponding to the next process, that is, comparing it with the number of sorted tobacco packages corresponding to the sorting process. By comparing the tobacco package production efficiency corresponding to two adjacent processes, it can be determined whether the tobacco packaging production line is in normal operation.

[0088] It is understandable that after obtaining the integrated data of the cigarette packs, the production line terminal can, but is not limited to, control the detection devices installed on the sorting process to collect multiple cigarette pack sorting data at preset time intervals. This cigarette pack sorting data can be understood as the time or speed required to sort a single cigarette pack. The average of all cigarette pack sorting data is calculated, and the result is transformed based on preset transportation data to obtain the corresponding sorting data average, such as, but not limited to, the number of cigarette packs sorted within a specified time period. The method for obtaining the sorting data average can be found in the above-described embodiment for obtaining the packaging data average, and will not be elaborated further here.

[0089] Next, after obtaining the average sorting data, the production line terminal can also, but is not limited to, calculate the difference between the integrated tobacco pack data and the preset transportation data, and the difference between the average sorting data and the preset transportation data, and calculate the second deviation corresponding to the two differences by combining the preset weights. That is, the tobacco packaging production line is in normal operation by jointly judging whether the tobacco packaging production line is in normal operation by the deviation of the number of tobacco packs corresponding to the packaging process and the transportation process, and the deviation of the number of tobacco packs corresponding to the sorting process and the transportation process.

[0090] Step 108: When the second deviation is detected to be less than the preset deviation threshold, stop outputting control signals to the circuit where the relay is located, so that the normally open contact corresponding to the relay and the circuit where the buffer cigarette pack depletion detection device is located are switched from the conducting state to the disconnected state.

[0091] Specifically, after calculating the second deviation used to characterize whether the tobacco packaging production line is in normal operation, when the second deviation is detected to be less than the preset deviation threshold, it indicates that the tobacco packaging production line is in normal operation. Then, the production line terminal can estimate the time required for the remaining number of cigarette packs in the cigarette pack buffer area to be exhausted based on the trend of the number of cigarette packs changing over time in the cigarette pack fitting curve mentioned above.
