Description

Technical Field

[0001] The present invention relates to the technical field of automated tobacco production, and in particular to a tobacco material out-of-cabinet conveying monitoring system, a monitoring method, a medium and a product. Background Art

[0002] In the tobacco-making workshop of a cigarette factory, storage cabinets and belt conveyor systems form the core of the material flow system. Their coordinated operation directly determines production continuity, process stability, and product quality. The storage cabinets serve as dynamic buffer hubs, storing tobacco leaves, cut tobacco, and other materials in layers through timed aging and temperature and humidity regulation, providing uniform raw materials for subsequent processes such as flavoring and cutting. The belt conveyor system, serving as the "arterial network" connecting the storage cabinets with upstream and downstream equipment, utilizes horizontal and inclined belt conveyors and uses electronic belt scales, photoelectric switches, and other detection units to monitor material status in real time, forming a closed-loop feedback control system.

[0003] However, the detection units in current conveyor belt systems for tobacco outbound transport are primarily located at the conveyor end, controlling and monitoring material flow at the entrance to the production equipment. Due to the large footprint of the silk-making workshop and the long distances between the storage cabinets and the production equipment, operators are unable to promptly monitor the material transport status when shortages or blockages occur during tobacco material outbound transport. This results in delayed response to faults and an increased probability of flow interruption, significantly impacting production continuity and efficiency, and in severe cases, potentially creating quality risks for the material. Summary of the Invention

[0004] The present invention provides a tobacco material out-of-cabinet conveying monitoring system, monitoring method, medium and product, which can solve the problem that material shortage and material blockage cannot be discovered in time during the out-of-cabinet material conveying process, which seriously affects production.

[0014] Optionally, the PLC is used to generate an abnormal handling instruction for controlling the shutdown of the storage cabinet discharge system when the result of the material shortage identification is material shortage and the result of the material blockage identification is material blockage.

[0015] Optionally, a PLC is used to obtain historical data on material blockage speed regulation, train a deep learning model based on the historical data on material blockage speed regulation, and obtain an automatic blockage removal model; when the blockage identification result is a material blockage, an abnormal handling instruction for adjusting the cabinet output speed is generated based on the automatic blockage removal model and the current running speed of the parallel belt at the bottom of the cabinet.

[0016] According to another aspect of the present invention, a method for monitoring tobacco material delivery out of a cabinet is provided, which is configured in a PLC and includes:

[0030] Example 1

[0031] Figure 1 This is a tobacco material out-of-cabinet delivery monitoring system provided in Example 1 of the present invention. Figure 1As shown, the tobacco material out-of-cabinet conveying monitoring system includes: an ultrasonic sensor, a color sensor, a PLC and an industrial computer; wherein the ultrasonic sensor, the color sensor and the industrial computer are respectively connected to the PLC for communication; the color sensor can be used to collect the color difference information of the inclined belt and transmit the color difference information of the inclined belt to the PLC; the ultrasonic sensor can be used to collect the material height on the parallel belt at the bottom of the storage cabinet and transmit the material height to the PLC; the PLC can be used to identify the material shortage anomaly based on the color difference information of the inclined belt and generate a material shortage identification result, and to identify the material blockage anomaly based on the material height and generate a material blockage identification result; based on the material shortage identification result and / or the material blockage identification result, an industrial computer early warning trigger signal and an abnormality handling instruction are generated; the industrial computer early warning trigger signal is sent to the industrial computer, and the storage cabinet discharge system is controlled according to the abnormality handling instruction; the industrial computer can be used to generate an early warning pop-up window information based on the industrial computer early warning trigger signal.

[0032] The inclined belt color difference information may describe the color change of the inclined belt, as detected by the color sensor, caused by material covering the inclined belt. For example, assuming the original color of the inclined belt is white and the tobacco material is brown, the inclined belt color difference information may include the time and duration of the white color appearing, and the time and duration of the brown color appearing. The industrial computer warning trigger signal may be a signal that triggers the industrial computer to issue a warning. The abnormality handling instruction may be an instruction generated by the PLC to resolve the abnormality based on the material shortage and / or material blockage identification results. The warning pop-up window information may be information displayed on the industrial computer describing the material shortage and / or material blockage status of the storage cabinet discharging system. The ultrasonic sensor calculates the real-time material height by the transmission-reception time difference. The color sensor can collect real-time color data of the parallel belt and its material surface. The parallel belt at the bottom of the storage cabinet is the conveyor belt of the parallel belt conveyor. The material shortage identification result may include material shortage or material availability. The material blockage identification result may include material blockage or material availability. Material shortage and material blockage are abnormal conditions.

[0033] In an embodiment of the present invention, an ultrasonic sensor, a color sensor, a PLC, and an industrial computer can be used to form a tobacco material out-of-cabinet conveyor monitoring system. The tobacco material out-of-cabinet conveyor monitoring system can use the color sensor to collect color difference information from the inclined belt and transmit this information to the PLC. The ultrasonic sensor can also collect the material height on the parallel belt at the bottom of the cabinet and transmit this information to the PLC. Based on the color difference information of the inclined belt, the PLC determines whether there is a material shortage state on the inclined belt, that is, whether there is uncovered material on the inclined belt, so as to obtain the material shortage identification result, and based on the material height on the parallel belt at the bottom of the storage cabinet, determines whether the material height on the parallel belt at the bottom of the storage cabinet is higher than the pre-set warning height limit position, so as to obtain an abnormal material blockage identification result when it is higher than the warning height limit position, and thus generates an industrial computer warning trigger signal and an abnormal handling instruction when any one of the identification results of the material shortage and the material blockage is abnormal, and then sends the industrial computer warning trigger signal to the industrial computer, so that the industrial computer generates a warning pop-up information according to the industrial computer warning trigger signal, and can also control the storage cabinet discharging system according to the abnormal handling instruction to realize automatic troubleshooting of the storage cabinet discharging system.

[0034] In a specific example, the position relationship of the components of the tobacco material out-of-cabinet conveying monitoring system can be seen in Figure 2 The ultrasonic sensor 2 is mounted above the parallel belt conveyor 8 at the bottom of the storage cabinet discharging system 1 via the ultrasonic sensor fixing bracket 7. The mounting position is aligned with the longitudinal centerline of the parallel belt conveyor 8, and the detection direction is perpendicular to the parallel belt surface. The color sensor 6 is mounted above the inclined belt conveyor 5 via the color sensor fixing bracket 4. The mounting position is aligned with the longitudinal centerline of the inclined belt conveyor 5, and the detection direction is perpendicular to the inclined belt surface. Figure 2 The tobacco material out-of-cabinet conveying monitoring system shown in the figure also has protective covers 3 set at the corners of the parallel belts.

[0035] The technical solution of the embodiments of the present invention utilizes ultrasonic sensors, color sensors, a programmable logic controller (PLC), and an industrial control computer. These ultrasonic sensors, color sensors, and the industrial control unit form a tobacco material out-of-cabinet conveying monitoring system. The PLC in this tobacco material out-of-cabinet conveying monitoring system automatically and in real time determines whether the cabinet discharging system is experiencing blockages or shortages based on data collected by the ultrasonic and color sensors. When blockages and / or shortages occur, the system adjusts the operating status of the cabinet discharging system to automatically troubleshoot the problem. The PLC also simultaneously generates a warning pop-up window on the industrial control computer, alerting operations and maintenance personnel to any anomalies and enabling them to assist in troubleshooting when necessary. This solves the problem of material shortages and blockages not being detected in a timely manner during the out-of-cabinet conveying process, which seriously impacts production. The system can promptly detect material shortages and blockages that occur during tobacco material transportation after leaving the cabinet, improving fault response efficiency and ensuring normal production.

[0036] Example 2

[0037] In an optional embodiment of the present invention, the PLC can be used to determine that a material shortage state occurs and generate a material shortage identification result when it is determined that the time for continuously detecting the original color of the inclined belt is greater than or equal to a first time threshold based on the color difference information of the inclined belt.

[0038] The original color of the inclined belt is the original color of the inclined belt. The first time threshold may be a preset maximum allowable time for the inclined belt to run without carrying material.

[0039] In an embodiment of the present invention, the PLC can determine the time during which the original color of the inclined belt is continuously detected based on the color difference information of the inclined belt, and compare the time during which the original color of the inclined belt is continuously detected with a first time threshold. If the time during which the original color of the inclined belt is continuously detected is greater than or equal to the first time threshold, it indicates that the time during which the inclined belt has not been running with material exceeds the maximum allowable time, that is, the inclined belt is in a material shortage state, and a material shortage identification result indicating a material shortage abnormality is generated.

[0040] In an optional embodiment of the present invention, the PLC can be used to calculate the current dynamic material height average based on the material height in the current time window; perform blockage anomaly identification based on the current material height and the current dynamic material height average to generate a blockage identification result.

[0041] The current time window may be a time window of a specified duration before the current acquisition time. The specified duration can be adjusted as needed, for example, 10 seconds. The current dynamic material height average may be the average material height within the current time window.

[0042] In an embodiment of the present invention, the current time window corresponding to the current material height can be determined first, and then the average of the material height under the current time window can be used as the current dynamic material height average. After the current material height exceeds a preset percentage (such as 20%) of the current dynamic material height average, it is determined that there is a blockage state, and a blockage identification result indicating that there is a blockage abnormality is generated.

[0043] Optionally, an absolute height limit can be set in the PLC, that is, the distance from the belt surface of the parallel belt conveyor to the upper plane of the corner guard cover. Then, after the current material height exceeds the preset percentage of the current dynamic material height average, it can be determined whether the current material height exceeds the absolute height limit. When it is determined that the absolute height limit is exceeded, the storage cabinet discharging system will be shut down immediately.

[0044] In an optional embodiment of the present invention, the PLC can also be used to generate a tobacco quality identification result when it is determined that the current tobacco color does not meet the target tobacco color based on the inclined belt color difference information, and send the tobacco quality identification result to the industrial computer.

[0045] The target tobacco color may be the normal color of tobacco materials shipped out of the counter. The tobacco quality pending inspection identification result may be data generated when the current tobacco color does not meet the target tobacco color, prompting a tobacco quality inspection.

[0046] In an embodiment of the present invention, the PLC can obtain the color of the tobacco material on the inclined belt, that is, the current color of the tobacco, from the color difference information of the inclined belt, and thus compare the current color of the tobacco with the target tobacco color. When the current color of the tobacco does not conform to the target tobacco color, it indicates that there may be a problem with the quality of the tobacco, and then generate an identification result of the tobacco quality to be checked, send the identification result of the tobacco quality to be checked to the industrial computer, and the industrial computer pops up a window to display an early warning for tobacco quality inspection.

[0047] In an optional embodiment of the present invention, the PLC can be used to obtain the number of pulses of the parallel belt at the bottom of the cabinet when the result of the material shortage identification is material shortage and the result of the material blockage identification is no material blockage, and generate an abnormal handling instruction for adjusting the speed of the cabinet bottom belt when it is determined that the cabinet is in the output empty section based on the number of pulses of the parallel belt at the bottom of the cabinet; obtain the status of the cabinet discharge knob and the status of the cabinet safety door, and generate an abnormal handling instruction for adjusting the status of the cabinet discharge knob and / or the status of the cabinet safety door when the status of the cabinet discharge knob is closed and / or the status of the cabinet safety door is open.

[0048] The cabinet discharge knob can be a knob that controls the discharge of materials from the cabinet. When the cabinet discharge knob is open, the cabinet can discharge materials; when the cabinet discharge knob is closed, the cabinet cannot discharge materials. The cabinet safety door can be an important protective device to ensure the stable operation of operators and equipment.

[0049] In an embodiment of the present invention, if the material shortage identification result identified by the PLC is material shortage, and the material blockage identification result is no material blockage, the number of parallel belt pulses at the bottom of the cabinet can be obtained, and based on the number of parallel belt pulses at the bottom of the cabinet, it can be determined whether it is in an empty section for out-of-cabinet transportation (which can be any section in the front section, middle section or tail section). If it is in an empty section for out-of-cabinet transportation, an abnormal handling instruction for adjusting the speed of the bottom belt of the cabinet is generated. If the material shortage identification result identified by the PLC is material shortage, and the material blockage identification result is no material blockage, the cabinet discharge knob status and the cabinet safety door status can also be obtained, and when the cabinet discharge knob status is closed, an abnormal handling instruction for adjusting the cabinet discharge knob status is generated, and / or when the cabinet safety door status is enabled, an abnormal handling instruction for adjusting the cabinet safety door status is generated.

[0050] In an optional embodiment of the present invention, the PLC can be used to generate an abnormal handling instruction for controlling the shutdown of the storage cabinet discharge system when the material shortage identification result is material shortage and the material blockage identification result is material blockage.

[0051] In an embodiment of the present invention, if the material shortage identification result obtained by the PLC is material shortage and the material blockage identification result is material blockage, an abnormal handling instruction can be generated to directly control the shutdown of the storage cabinet discharge system to avoid more serious production accidents.

[0052] In an optional embodiment of the present invention, the PLC can be used to obtain historical data on material blockage speed regulation, train a deep learning model based on the historical data on material blockage speed regulation, and obtain an automatic blockage removal model; when the blockage identification result is a material blockage, an abnormal handling instruction for adjusting the cabinet output speed is generated based on the automatic blockage removal model and the current running speed of the parallel belt at the bottom of the cabinet.

[0053] The historical data on material jam speed regulation can include data related to adjusting the output speed of the cabinet when a material jam occurs on the parallel belt at the bottom of the cabinet. This data can include, but is not limited to, the operating speed of the parallel belt at the bottom of the cabinet and the cabinet output speed. The automatic jam removal model can be a deep learning model trained using this historical data.

[0054] In an embodiment of the present invention, the PLC can obtain historical data on material blockage speed regulation, and use the historical data on material blockage speed regulation to train a deep learning model to obtain an automatic blockage removal model. When a blockage is detected on the parallel belt at the bottom of the storage cabinet, the current running speed of the parallel belt at the bottom of the storage cabinet is input into the automatic blockage removal model to obtain the required storage cabinet output speed, thereby generating an abnormal handling instruction to adjust the current output speed of the storage cabinet to the required storage cabinet output speed, thereby realizing automatic adjustment of the blockage status.

[0055] Optionally, while the industrial computer displays the warning pop-up information, it can also activate the sound and light alarm lights.

[0056] In a specific example, an ultrasonic sensor can be used to collect the material height on the parallel belt at the bottom of the storage cabinet, and the PLC can be used to determine whether a material blockage has occurred. If a material blockage has occurred, an industrial computer and an audible and visual alarm light can be used to issue an early warning. Furthermore, the color difference information of the inclined belt, collected by the color sensor, can be used to determine whether a material shortage has occurred. If a material shortage has occurred, an early warning can also be issued via the industrial computer and an audible and visual alarm light. If both a material shortage and a blockage occur, the cabinet discharging system can be shut down, prompting the appropriate maintenance personnel to perform maintenance. If a material blockage has occurred but no material shortage has occurred, an early warning can be issued via the industrial computer and an audible and visual alarm light. If neither a material blockage nor a material shortage has occurred, the process ends.

[0057] The technical solution of the embodiment of the present invention uses ultrasonic sensors, color sensors, and industrial control mechanisms to build a tobacco material out-of-cabinet conveying monitoring system. Using a multi-sensor fusion approach, the ultrasonic and color sensors comprehensively monitor the tobacco material out-of-cabinet conveying process. This system can promptly and accurately detect material blockages and shortages, promptly notify personnel via an industrial control computer and an audible and visual alarm, and automatically stop the cabinet discharge system when necessary. This effectively ensures smooth tobacco material conveying and stable production, reduces equipment damage and production accidents, and improves tobacco processing efficiency and product quality. It automatically and in real time determines whether the cabinet discharge system is blocked or short. When blockages and / or shortages occur, the operating status of the cabinet discharge system is adjusted to automatically troubleshoot the problem. A warning pop-up window is simultaneously generated on the industrial control computer to promptly alert maintenance personnel to the anomaly and assist in troubleshooting when necessary. This solves the problem of material shortages and blockages not being detected in time during the out-of-cabinet material conveying process, which seriously impacts production. It can promptly detect material shortages and blockages that occur during tobacco material transportation after being out of the cabinet, improve fault response efficiency, and ensure normal production.

[0058] Example 3

[0059] Figure 3 This is a flow chart of a tobacco material out-of-cabinet conveying monitoring method provided by the third embodiment of the present invention. The tobacco material out-of-cabinet conveying monitoring method is executed by the PLC in the tobacco material out-of-cabinet conveying monitoring system. Figure 3 As shown, the method includes:

[0060] Step 310: Based on the color difference information of the inclined belt, identify the material shortage anomaly and generate a material shortage identification result; and based on the material height, identify the material blockage anomaly and generate a material blockage identification result.

[0061] Step 320: Generate an industrial computer warning trigger signal and an abnormality handling instruction based on the material shortage identification result and / or the material blockage identification result.

[0062] Step 330: Send the industrial computer early warning trigger signal to the industrial computer, and control the storage cabinet discharge system according to the abnormal handling instruction.

[0063] Optionally, based on the color difference information of the inclined belt, material shortage abnormality identification is performed to generate a material shortage identification result, including: when it is determined that the time for continuously detecting the original color of the inclined belt is greater than or equal to a first time threshold based on the color difference information of the inclined belt, it is determined that a material shortage state occurs, and the material shortage identification result is generated.

[0064] Optionally, based on the material height, abnormal material blockage is identified and a material blockage identification result is generated, including: calculating the current dynamic material height mean based on the material height in the current time window; based on the current material height and the current dynamic material height mean, abnormal material blockage is identified and the material blockage identification result is generated.

[0065] Optionally, the tobacco material out-of-cabinet conveying monitoring method further includes: when it is determined based on the color difference information of the inclined belt that the current color of the tobacco does not meet the target tobacco color, generating a tobacco quality identification result to be checked, and sending the tobacco quality identification result to the industrial computer.

[0066] Optionally, based on the material shortage identification result and / or the material blockage identification result, an industrial computer early warning trigger signal and an abnormal handling instruction are generated, including: when the material shortage identification result is material shortage and the material blockage identification result is no material blockage, obtaining the number of parallel belt pulses at the bottom of the cabinet, and when it is determined that the cabinet is in the output idle section based on the number of parallel belt pulses at the bottom of the cabinet, generating an abnormal handling instruction for adjusting the cabinet bottom belt speed; obtaining the cabinet discharge knob status and the cabinet safety door status, and generating an abnormal handling instruction for adjusting the cabinet discharge knob status and / or the cabinet safety door status when the cabinet discharge knob status is closed and / or the cabinet safety door status is open.

[0067] Optionally, based on the material shortage identification result and / or the material blockage identification result, an industrial computer early warning trigger signal and an abnormal handling instruction are generated, including: when the material shortage identification result is material shortage and the material blockage identification result is material blockage, generating an abnormal handling instruction for controlling the shutdown of the storage cabinet discharge system.

[0068] Optionally, based on the material shortage identification result and / or the material blockage identification result, an industrial computer warning trigger signal and an abnormal handling instruction are generated, including: obtaining historical data of material blockage speed regulation, training a deep learning model based on the historical data of material blockage speed regulation, and obtaining an automatic blockage removal model; when the material blockage identification result is material blockage, generating an abnormal handling instruction for adjusting the cabinet output speed based on the automatic blockage removal model and the current running speed of the parallel belt at the bottom of the cabinet.

[0069] The technical solution of the embodiment of the present invention uses the PLC in the tobacco material out-of-cabinet conveying monitoring system to automatically and in real time determine whether the storage cabinet discharging system is blocked or short of material based on data collected by ultrasonic sensors and color sensors. When blockage and / or short of material occurs, the operating status of the storage cabinet discharging system is adjusted to automatically troubleshoot, and an early warning pop-up window message is simultaneously generated on the industrial control computer to remind operation and maintenance personnel in time to pay attention to abnormalities so that auxiliary troubleshooting can be carried out when necessary. This solves the problem that the shortage and blockage of material cannot be discovered in time during the out-of-cabinet material conveying process, which seriously affects production. It can timely discover the shortage and blockage of tobacco materials during transportation after they are out of the cabinet, improve fault response efficiency, and ensure normal production.
