[0027] Figure 2This is a flowchart illustrating a filter rod storage management method provided in an embodiment of the present invention. The method is applied to a filter rod storage tank. A camera is positioned to the side of the filter rod storage tank in the direction of conveying filter rods to the filter media hopper. The method can be executed by a filter rod storage management device provided in this embodiment of the invention, which can be implemented using software and / or hardware. In a specific embodiment, the device can be integrated into an electronic device, such as a computer or server. The following embodiments will illustrate this using the integration of the device into an electronic device as an example. (Reference) Figure 2 The method may specifically include the following steps:

[0028] Step 201: Acquire a real-time status image of the filter rod stacking structure in the filter rod storage library using a camera device. The real-time status image includes image information of the coplanar combined sides of the filter rod stacking structure. This step enables the acquisition of the real-time storage status of the filter rods in the filter rod storage library based on the real-time status image of the filter rod stacking structure.

[0029] Specifically, the locations of the aforementioned camera equipment are as follows: Figure 3 As shown, the number of camera devices can be one or multiple.

[0030] Specifically, the horizontal distance, rotation angle, and vertical position of the camera relative to the filter rod storage can all be adjusted.

[0031] Specifically, the image information of the aforementioned coplanar combined side is as follows: Figure 4 As shown, it can be image information of the end faces of regularly stacked filter rods.

[0032] Specifically, the process of acquiring real-time status images of the filter rod stacking structure in the filter rod storage library using a camera device may include: capturing real-time status images of the filter rod stacking structure in the filter rod storage library based on a preset shooting frequency.

[0033] Specifically, the process of acquiring a real-time status image of the filter rod stacking structure in the filter rod storage library using a camera device may include: capturing a real-time status image of the filter rod stacking structure in the filter rod storage library in response to a shooting command sent by the user.

[0034] Step 202: Obtain the real-time storage status of filter rods in the filter rod storage library based on the real-time status image. The real-time storage status of filter rods in the filter rod storage library includes the real-time inventory status, stacking structure crowding status, and / or stacking structure regularity status of filter rods in the storage library. This step enables refined management of filter rods in the filter rod storage library based on their real-time storage status.

[0035] Specifically, the above inventory status can be used to indicate whether the inventory quantity of filter rods in the filter rod storage is a healthy inventory quantity, the above stacking structure crowding status can be used to indicate the degree of crowding of filter rods in the filter rod storage due to space limitations, and the above stacking structure regularity status can be used to indicate whether the filter rods in the filter rod storage are stacked in a permissible regular form.

[0036] Specifically, the process of obtaining the real-time storage status of filter rods in the filter rod storage based on the real-time status image may include: determining the real-time inventory status index value based on the real-time status image, comparing the pre-determined healthy inventory status index value with the real-time inventory status index value, and determining the inventory status of filter rods in the filter rod storage based on the comparison result.

[0037] Specifically, the process of obtaining the real-time storage status of filter rods in the filter rod storage library based on the real-time status image may include: determining the real-time congestion status index value based on the real-time status image, comparing the pre-determined normal congestion status index value with the real-time congestion status index value, and determining the congestion status of the filter rod stacking structure based on the comparison result.

[0038] Specifically, the process of obtaining the real-time storage status of filter rods in the filter rod storage library based on the real-time status image may include: determining the real-time rule status index value based on the real-time status image, comparing the pre-determined allowed rule status index value with the real-time rule status index value, and determining the rule status of the filter rod stacking structure based on the comparison result.

[0039] Step 203 involves managing the storage of filter rods in the filter rod storage warehouse based on real-time storage status. Building upon steps 201 and 202, this step improves the accuracy of filter rod storage management, preventing disruptions to filter rod supply during cigarette production and meeting the refined management requirements of cigarette manufacturing for filter rods in the storage warehouse.

[0040] Specifically, the process of managing the storage of filter rods in the filter rod storage warehouse based on real-time storage status includes: maintaining a healthy inventory level for the filter rods in the filter rod storage warehouse; adjusting the storage space size of the filter rods in the filter rod storage warehouse to maintain a normal level of crowding; and adjusting the storage form of the filter rods in the filter rod storage warehouse to ensure that the filter rods are stored in a regular stacked form.

[0041] The following further describes the filter rod storage management method provided by the embodiments of the present invention, such as... Figure 5 As shown, that is Figure 1 Step 102 may include the following steps:

[0042] Step 102A1: Determine the first geometric feature parameters of the filter rod stack structure based on the real-time state image.

[0043] Optionally, the first geometric characteristic parameter of the filter rod stack structure includes the coplanar combined lateral surface area of ​​the filter rod stack structure.

[0044] Specifically, the first geometric feature parameter mentioned above may also include other geometric parameters, such as the volume of the filter rod stack structure.

[0045] Specifically, the area of ​​the coplanar combined side surface of the filter rod stack structure in the real-time state image can be obtained through image geometric quantization.

[0046] Step 102A2: Determine the inventory status of filter rods in the filter rod storage bin based on the first geometric feature parameters of the filter rod stacking structure.

[0047] Optionally, the process of determining the inventory status of filter rods in the filter rod storage based on the first geometric feature parameter of the filter rod stacking structure includes: when the coplanar combined lateral surface area of ​​the filter rod stacking structure is less than the coplanar combined lateral surface area corresponding to the healthy inventory of filter rods in the filter rod storage, the inventory status of filter rods in the filter rod storage is determined to be insufficient.

[0048] Specifically, the coplanar combined lateral surface area corresponding to the aforementioned healthy inventory level can be determined based on empirical data or on the results of multiple experiments.

[0049] Specifically, the coplanar combined lateral surface area corresponding to the above-mentioned healthy inventory level can be a single area value or a range of area values.

[0050] Specifically, when the coplanar combined lateral surface area of ​​the filter rod stack structure is less than the minimum value of the above area range, it can be determined that the coplanar combined lateral surface area of ​​the filter rod stack structure is less than the coplanar combined lateral surface area corresponding to the healthy inventory of filter rods in the filter rod storage warehouse.

[0051] Specifically, when the coplanar combined lateral surface area of ​​the filter rod stacking structure is any value within the range of the above-mentioned area values, the inventory status of the filter rods in the filter rod storage warehouse can be determined as sufficient.

[0052] Specifically, when the volume of the filter rod stack structure is less than the volume of the filter rod stack structure corresponding to the healthy inventory of filter rods in the filter rod storage warehouse, the inventory status of the filter rods in the filter rod storage warehouse can be determined as insufficient inventory.

[0053] Optionally, the aforementioned process of adjusting the inventory of filter rods in the filter rod storage warehouse based on the inventory status of filter rods in the filter rod storage warehouse includes: adjusting the inventory of filter rods in the filter rod storage warehouse based on the inventory status of filter rods in the filter rod storage warehouse.

[0054] Optionally, the process of adjusting the inventory of filter rods in the filter rod storage based on the inventory status of filter rods in the filter rod storage includes: when the inventory status is insufficient, sending a filter rod request signal to the filter rod transmitter to cause the filter rod transmitter to send filter rods to the filter rod storage to increase the inventory of filter rods in the filter rod storage.

[0055] Specifically, when the inventory status is insufficient, an insufficient inventory prompt message can be sent to the user, so that the user can control the filter rod transmitter to send filter rods to the filter rod storage to increase the inventory of filter rods in the filter rod storage.

[0056] Specifically, when the inventory status is sufficient, a notification message indicating sufficient inventory can be sent to the user.

[0057] Specifically, when the inventory status is sufficient, a filter rod stop request signal can be sent to the filter rod transmitter to stop sending filter rods to the filter rod storage warehouse, thereby increasing the inventory of filter rods in the filter rod storage warehouse.

[0058] The embodiments of the present invention can accurately manage the inventory of filter rods in the filter rod storage warehouse, avoiding the problem of insufficient supply of filter rods during the cigarette production process.

[0059] The filter rod storage and management method provided in the embodiments of the present invention will be further described below.

[0060] Optionally, the filter rod storage chamber is equipped with a tensioning cloth belt and a cloth belt tensioning mechanism. When the tension of the tensioning cloth belt is reduced by the cloth belt tensioning mechanism, the stacking space of the filter rods in the filter rod storage chamber increases. When the tension of the tensioning cloth belt is increased by the cloth belt tensioning mechanism, the stacking space of the filter rods in the filter rod storage chamber decreases.

[0061] In a specific instance, such as Figure 3 As shown, the belt tensioning mechanism includes a slide table and a winding roller. When the slide table moves in the direction of filter rod feeding while keeping the winding roller stationary, the tension of the belt increases. When the slide table moves in the opposite direction of filter rod feeding while keeping the winding roller stationary, the tension of the belt decreases.

[0062] Optional, such as Figure 6 As shown, that is Figure 1 Step 102 may include the following steps:

[0063] Step 102B1: Determine the second geometric feature parameters of the filter rod stack structure based on the real-time state image.

[0064] Optionally, the second geometric feature parameter of the filter rod stack structure includes the coplanar combined side height of the filter rod stack structure.

[0065] Specifically, the second geometric feature parameter of the above-mentioned filter rod stack structure may also include other geometric feature parameters of the filter rod stack structure, such as the coplanar combined lateral surface area of ​​the filter rod stack structure.

[0066] Specifically, the image geometric quantization method is used to obtain the height of the coplanar combined lateral surface area of ​​the filter rod stack structure in the real-time state image.

[0067] Step 102B2: Determine the crowding state of the filter rod stack structure based on the second geometric feature parameters of the filter rod stack structure.

[0068] Optionally, the process of determining the crowding state of the filter rod stack structure based on the second geometric characteristic parameter of the filter rod stack structure includes: when the height of the coplanar combined side of the filter rod stack structure is greater than the height of the coplanar combined side corresponding to the normal crowding state of the filter rod stack structure, the crowding state of the filter rod stack structure is determined to be an overcrowded state.

[0069] Specifically, the coplanar combined side height corresponding to the above-mentioned normal congestion state can be determined based on empirical data or on the results of multiple tests.

[0070] Specifically, the coplanar combined side height corresponding to the above-mentioned normal congestion state can be a single height value or a range of height values.

[0071] Specifically, when the height of the coplanar combined side of the filter rod stack structure is greater than the maximum value of the above area range, it can be determined that the height of the coplanar combined side of the filter rod stack structure is greater than the height of the coplanar combined side of the filter rod stack structure corresponding to the normal crowded state.

[0072] Specifically, when the height of the coplanar combined side of the filter rod stack structure is any value within the range of the above-mentioned area values, the congestion state of the filter rod stack structure can be determined as a normal congestion state.

[0073] Specifically, the crowding state of the filter rod stack structure can be determined based on the position of the slide and the coplanar combined lateral surface area of ​​the filter rod stack structure.

[0074] Specifically, the crowded state of the filter rod stacking structure can be defined as an overcrowded state when the position of the slide is not located at the end opposite to the filter rod conveying direction, and the coplanar combined side area is not less than the coplanar combined side area corresponding to the healthy inventory of filter rods in the filter rod storage warehouse.

[0075] Specifically, when the height of the coplanar combined side of the filter rod stack structure is any value within the range of the above-mentioned area values, the congestion state of the filter rod stack structure can be determined as a normal congestion state.

[0076] Optionally, the aforementioned process of adjusting the stacking space of filter rods in the filter rod storage library based on the crowding state of the filter rod stacking structure includes: adjusting the stacking space of filter rods in the filter rod storage library based on the crowding state of the filter rod stacking structure.

[0077] Optionally, the process of adjusting the stacking space of filter rods in the filter rod storage tank based on the crowding state of the filter rod stacking structure includes: when the crowding state of the filter rod stacking structure is overcrowded, reducing the tension of the tensioning belt through the belt tensioning mechanism to increase the stacking space of the filter rods in the filter rod storage tank.

[0078] Specifically, the process of reducing the tension of the tensioned cloth belt through the cloth belt tensioning mechanism includes: controlling the slide to move in the opposite direction to the filter rod conveying direction to increase the stacking space of the filter rods in the filter rod storage tank.

[0079] Specifically, the slide can be controlled to move in the opposite direction to the filter rod conveying direction until the height of the coplanar combined side of the filter rod stack structure is any value within the range of the above-mentioned area values.

[0080] It is understandable that filter rods are mostly made of materials such as cellulose acetate, which are relatively fragile. Overcrowding can cause continuous compression between filter rods, easily leading to problems such as deformation and loosening of the structure. The embodiments of the present invention can help avoid the impact on the shape and performance of filter rods caused by overcrowding.

[0081] The following further describes the filter rod storage management method provided by the embodiments of the present invention, such as... Figure 7 As shown, that is Figure 1 Step 102 may include the following steps:

[0082] Step 102C1: Identify irregularly stacked filter rods in the filter rod stacking structure based on real-time status images.

[0083] Optionally, the above process of identifying irregularly stacked filter rods in the filter rod stacking structure based on real-time state images includes: obtaining irregularly stacked filter rods in the filter rod stacking structure based on real-time state images through a pre-trained irregularly stacked filter rod recognition model. The irregularly stacked filter rods include horizontally placed filter rods and / or filter rods that enclose and form large-area holes in the filter rod stacking structure. The area of ​​the large-area holes is greater than the allowable void area threshold.

[0084] Specifically, the aforementioned permissible void area threshold can be determined based on empirical data, or it can be determined based on the test results after conducting multiple tests on the impact of void area on filter rod quality and supply.

[0085] Specifically, the network structure of the aforementioned irregularly stacked filter rod recognition model can be a convolutional neural network (CNN) or a fully convolutional network (FCN), etc.

[0086] Specifically, the irregularly stacked filter rod recognition model can be trained based on sample images of irregularly stacked filter rod structures. These images include horizontally placed filter rods and / or filter rods that enclose large-area holes within the stacked structure.

[0087] Specifically, the training process for the irregularly stacked filter rod recognition model can be carried out using the cross-entropy loss function or the focus loss function through stochastic gradient descent.

[0088] Step 102C2: Determine the regularity of the filter rod stacking structure based on the identification results of the irregularly stacked filter rods.

[0089] Optionally, the process of determining the regular state of the filter rod stacking structure based on the identification result of irregularly stacked filter rods includes: when irregularly stacked filter rods are identified, determining the regular state of the filter rod stacking structure as an unacceptable form.

[0090] Specifically, when the number of irregularly stacked filter rods exceeds a certain threshold, the regular state of the filter rod stacking structure can be defined as an unacceptable state.

[0091] Specifically, the aforementioned quantity thresholds can be determined based on empirical data or based on the number of irregularly stacked filter rods when they obstruct the supply of filter rods.

[0092] Specifically, the number of irregularly stacked filter rods that obstruct the supply of filter rods can be determined through multiple experiments.

[0093] Optionally, the aforementioned process of managing the storage of filter rods in the filter rod storage library based on real-time storage status includes: performing regularized stacking management of filter rods in the filter rod storage library based on the regular status of the filter rod stacking structure.

[0094] Optionally, the aforementioned process of managing the storage of filter rods in the filter rod storage library based on real-time storage status includes: performing regularized stacking management of filter rods in the filter rod storage library based on the regular status of the filter rod stacking structure.

[0095] Optionally, the process of performing regular stacking management of filter rods in the filter rod storage library based on the rule status of the filter rod stacking structure includes: when the rule status of the filter rod stacking structure is an unallowed state, sending an alarm message to the user so that the user can perform regular stacking processing on the filter rods in the filter rod storage library.

[0096] Specifically, when the filter rod stacking structure is in an unacceptable state, the stacking space of the filter rods in the filter rod storage chamber can be increased by reducing the tension of the tensioning belt to adjust the stacking structure to an acceptable state.

[0097] Specifically, when the rule status of the filter rod stack structure is in the allowed state, a prompt message can be sent to the user indicating that the rule status of the filter rod stack structure is in the allowed state.

[0098] It is understandable that when there are irregularly stacked filter rods in the filter rod stacking structure, such as horizontally placed filter rods, some filter rods may become overcrowded, and may also cause blockages in the filter rod supply process. The embodiments of the present invention can avoid the impact of irregular filter rods on the shape and performance of filter rods, and avoid supply blockages caused by irregular filter rods, thus ensuring the normal supply of filter rods in the cigarette production process.

[0101] Optionally, the filter rod storage chamber is equipped with a tensioning cloth belt and a cloth belt tensioning mechanism. When the tension of the tensioning cloth belt is reduced by the cloth belt tensioning mechanism, the stacking space of the filter rods in the filter rod storage chamber increases. When the tension of the tensioning cloth belt is increased by the cloth belt tensioning mechanism, the stacking space of the filter rods in the filter rod storage chamber decreases.
