[0003] During the process of transferring items through the pass-through window, the window of the pass-through window needs to be opened manually, and the items are placed inside. When both windows of the pass-through window are locked, the pass-through window uses ozone to disinfect the items. After disinfection and removal of ozone from the items, the other window is opened to retrieve the disinfected items.
[0004] During the transfer of items through a pass-through window, if items are stacked on top of each other, the overlapping surfaces between the items are difficult to disinfect or the disinfection efficiency is low, thus reducing the efficiency of the pass-through window in transferring items.

Brief Description of the Drawings
[0020] Figure 1 is a flowchart of a control method for a transfer window according to an embodiment of the present invention; Figure 2 is a schematic diagram when the articles in the transfer window of the embodiment of the present invention are tilted.
[0021] The names of the parts referred to by the various numerical labels in the above drawings are as follows: 1. Marked articles. Detailed Embodiment
[0022] The present invention will be further described in detail below in conjunction with the drawings and embodiments.
[0023] Refer to Figure 1 And Figure 2 , the embodiment of the present application discloses a control method for a transfer window, including the following steps: S10: Collect image detection information inside the transfer window.
[0024] The image detection information refers to the image inside the transfer window, which is obtained by shooting with a camera preset inside the transfer window.
[0025] S11: Identify the stacking shape from the image detection information.
[0026] The stacking shape refers to the shape of the articles stacked inside the transfer window. By identifying the positions of each article from the image detection information and taking the shape of the articles with stacking as the stacking shape, the analysis method of the stacking shape is well-known common knowledge to those skilled in the art and will not be elaborated here. In this embodiment, the stacking shape is the shape of the articles stacked in a "pin" shape.
[0027] S12: Responds to the stacked shape to obtain the tilt angle.
[0028] The tilt angle refers to the angle at which the overlapping surfaces of stacked items can be tilted to achieve maximum ozone coverage. It is determined by analyzing the compressive strength of each item in the stack and taking the maximum angle at which each item can tilt without deformation as the tilt angle.
[0029] The method of determining the tilt angle by analyzing the compressive strength of an object is common knowledge to those skilled in the art and will not be elaborated here.
[0030] S13: Based on the tilt angle and stacking shape to obtain the tilt position, control the preset auxiliary device to tilt the item at the tilt angle and tilt position.
[0031] The tilt position refers to the position used to control the tilting of an item. By analyzing the tilt angle, the side of the item that needs to be tilted is determined, and the position of the side of the item that needs to be tilted is identified from the stacking shape as the tilt position. The tilt angle and tilt position of the auxiliary device are then controlled to tilt the item.
[0032] The auxiliary device is a telescopic rod installed on the inner wall of the transfer window and operating symmetrically. A slide rail is provided on the inner wall of the transfer window to allow the telescopic rod to change position. The telescopic rod extends and retracts using hydraulic or pneumatic principles, which will not be elaborated upon here.
[0033] In this embodiment, the area of the transfer window used for placing items is equipped with a turntable for the items to rotate.
[0034] Also includes: S20: Identify the type of items in the stacked shape from the image detection information.
[0035] Item characteristics are the features set by technicians for items that need to be placed in the pass-through window.
[0036] Item type refers to the type of items in a stacked shape. It is determined by identifying the type of items in the stacked shape based on the features of the items detected from the image.
[0037] S21: When the item type contains a preset soft porous type, the item that identifies the soft porous type from the stack shape is defined as a soft item.
[0038] The "soft porous type" is a type of item designed by technicians for placement within the transfer window using soft, porous materials. The soft porous type can be a sponge or a cleanroom cloth wrapped around a cylinder.
[0039] Soft items refer to items that are soft and porous. When an item type includes the soft and porous type, it means that there are soft and porous items in the stacked shape. Items that are identified as soft and porous from the stacked shape are defined as soft items.
[0040] S22: Responds to stacked shapes and soft objects to obtain marked item 1 and marked position.
[0041] Marked item 1 refers to a soft item on top of other items, and the marked position refers to the location of marked item 1 on the stack shape. Marked item 1 is identified from the stack shape by identifying the soft item on top of other items, and the marked position is identified from the stack shape by identifying the location of marked item 1.
[0042] S23: Collect scan information of marked item 1.
[0043] Scan information refers to the information obtained by scanning the marked item 1 using a scanner.
[0044] S24: Obtain the pore cleaning time based on the scanning information, the marked position, and the preset reference output speed.
[0045] The reference output speed is the speed at which ozone is ejected from the transfer window as set by the technician.
[0046] The pore cleaning time refers to the time required to disinfect and clean the pores of the marked item 1. The pore cleaning time is obtained by analyzing the scanning information, the marking position, and the reference output speed.
[0047] S25: Acquire reference output time.
[0048] The reference output time refers to the length of time that ozone is emitted within the transfer window. Timing is performed when the transfer window is locked and ozone is output, and the timing result is used as the reference output time.
[0049] S26: When the reference output time is consistent with the pore cleaning time, respond to the stacking shape to obtain the mark compression information, and control the auxiliary device to compress the marked item 1 with the mark compression information.
[0050] The marking compression information refers to the parameters used to compress the marked item 1. When the reference output time is consistent with the pore cleaning time, it indicates that the pores in the marked item 1 have been disinfected. The marking compression information is obtained by analyzing the stack shape, and the auxiliary device is controlled to compress the marked item 1 according to the marking compression information.
[0051] S27: Update tilt position by marking squeeze information.
[0052] Since the marked item 1 can meet the strength of the upper item stacking pressure after being squeezed, the upper item can be tilted at the same time as the marked item 1, and the tilting of the upper item can be reduced by one auxiliary device. At this time, the tilt angle of the upper item does not need to meet the tilt angle.
[0053] Methods for obtaining pore cleaning time include: S30: Combine scan information to form a marker model.
[0054] The marker model refers to the virtual three-dimensional model of the marked item 1. The marker model is obtained by analyzing the scanned information. The method of forming the marker model is common knowledge to those skilled in the art and will not be elaborated here.
[0055] S31: Identify pore throughput from the labeled model.
[0056] Pore throughput refers to the rate at which ozone can pass through the pores of the marked article 1. This is determined by retrieving the pore shape from the marking model and matching it against a pre-defined pore reference table. The pore reference table stores the pore throughput corresponding to different pore shapes; the larger the volume corresponding to a given pore shape, the more ozone passes through, and the higher the pore throughput. The parameters in the pore reference table are pre-set experimentally by those skilled in the art based on actual conditions and will not be elaborated upon here.
[0057] S32: Responds to item 1, pore throughput, and stacking shape to achieve maximum throughput.
[0058] Maximum throughput refers to the amount of ozone that passes through marked item 1 per unit time. Maximum throughput is obtained by analyzing marked item 1, porosity, and stacking shape.
[0059] S33: Calculate the marker position and the preset reference output position to obtain the reference output distance.
[0060] The reference output position is the location point within the transfer window where ozone is output, as set by the technician. The reference output position represents the method of ozone output. In this embodiment, the reference output position is located at the top inside the transfer window to blow ozone from top to bottom.
[0061] The reference output distance refers to the distance from which ozone flows to the marked item 1. The reference output distance is calculated by taking the straight-line distance between the marked position and the reference output position.
[0062] S34: The pore cleaning time is obtained by using the reference output distance, maximum throughput, and reference output speed.
[0063] The pore cleaning time is determined by matching the reference output distance, maximum throughput, and reference output speed from the pore lookup table. The pore lookup table also stores the pore cleaning time corresponding to different reference output distances, maximum throughputs, and reference output speeds. The smaller the reference output distance, the larger the maximum throughput, and the larger the reference output speed, the shorter the pore cleaning time. This will not be elaborated upon here.
[0064] Methods for obtaining the maximum throughput include: S40: Retrieve the stacked item on marked item 1 from the stacked shape.
[0065] Stacked items refer to items stacked on top of marked item 1, and are retrieved from the stack shape as stacked items.
[0066] S41: Retrieve the stack weight of stacked items.
[0067] Stack weight refers to the total weight of stacked items. It is calculated by retrieving the weight of each stacked item and summing the results.
[0068] S42: Responds to the marked item 1 and tilt angle to obtain the tilt contact position.
[0069] The tilted contact position refers to the position where the marked item 1 contacts the stacked items when it is tilted at an angle. The tilted contact position is obtained by analyzing the marked item 1 and the tilt angle. The method for analyzing the tilted contact position is common knowledge to those skilled in the art and will not be elaborated here.
[0070] S43: Based on the tilted contact position and stack weight, obtain the marked pressure weight.
[0071] The marked pressure weight refers to the weight value of stacked items pressing down on the inclined contact point. Since the inclined contact point can be located at different positions on the bottom of the stacked items, the downward pressure torque of the stacked items varies depending on the position that causes the stacked items to tilt. Therefore, the marked pressure weight is obtained by performing torque-weight analysis on the inclined contact point and the stacked weight. The analysis method for the marked pressure weight is common knowledge to those skilled in the art and will not be elaborated here.
[0072] S44: The degree of deformation under pressure is obtained by marking the pressure weight and tilt angle.
[0073] The degree of downward deformation refers to the degree of deformation of the marked item 1 under the downward pressure of the marker at an inclined angle. The degree of downward deformation is determined by matching the marker's downward pressure weight with the inclination angle from a preset deformation lookup table. The deformation lookup table stores the degree of downward deformation of the marked item 1 corresponding to different marker downward pressure weights and inclination angles. As the inclination angle changes, the contact area between the marked item 1 and the stacked items also changes. At this time, the greater the marker's downward pressure weight, the greater the degree of downward deformation. The parameters in the deformation lookup table are set in advance by those skilled in the art based on actual conditions through experiments, and will not be elaborated here.
[0074] S45: Update the pore throughput by the degree of downward deformation, and obtain the maximum throughput by comparing the pore throughput with the reference output speed.
[0075] The new pore throughput is matched from the pore reference table by the degree of downward deformation. The pore reference table stores the pore throughput corresponding to different degrees of downward deformation. The greater the degree of downward deformation, the smaller the pore throughput. This will not be elaborated here. The maximum throughput is obtained by analyzing the pore throughput and the reference output speed.
[0076] Methods for obtaining tagged compression information include: S50: Support strength is achieved by stacking weight.
[0077] Support strength refers to the strength with which marked item 1 supports the weight of the stack, and the value of the stack weight is used as the support strength.
[0078] S51: Responds to the support force and the marked item 1 to obtain the support density.
[0079] Support density refers to the density required when the marked item 1 supports the stacked items with support force. The support density is obtained by matching the support force with the marked item 1 from the deformation lookup table. The deformation lookup table also stores the support density corresponding to different support forces and marked items 1. When the marked item 1 remains unchanged, the greater the support force, the greater the support density. This will not be elaborated here.
[0080] S52: Retrieve the marker density from the marker model.
[0081] The marker density refers to the average density of the marked item 1, which is obtained by retrieving the marker density from the marker model.
[0082] S53: Update the marker density by the degree of compression deformation.
[0083] Match a new marking density from the deformation comparison table according to the degree of downward deformation. Different marking densities corresponding to different degrees of downward deformation are also stored in the deformation comparison table. Without further elaboration, when the marked item 1 remains unchanged, the greater the degree of downward deformation, the greater the marking density.
[0084] S54: Calculate the difference between the marking density and the support density as the density deviation value.
[0085] The density deviation value refers to the deviation value between the marking density and the support density, and the difference between the marking density and the support density is calculated as the density deviation value.

[0087] The extrusion force refers to the force value required to extrude the marking density into the support density, and the extrusion area refers to the area where the auxiliary device needs to extrude the marked item 1 with the extrusion force. The extrusion force is matched from the deformation comparison table through the density deviation value. Different extrusion forces corresponding to different density deviation values are also stored in the deformation comparison table. Without further elaboration, the greater the density deviation value, the greater the extrusion force. Then, the area of the side of the marked item 1 where the inclined position is located is used as the extrusion area, and the extrusion force and the extrusion area are defined as the marking extrusion information.
[0088] It further includes: S60: Obtain the occlusion direction through the tilt angle and the preset reference output direction.
[0089] The reference output direction is the direction in which the transfer window outputs ozone set by the technician. The reference output direction is the direction from top to bottom.
[0090] The occlusion direction refers to the direction in which the item is occluded by ozone, and the occlusion direction is obtained by analyzing the tilt angle and the reference output direction. For example, if the reference output direction is from top to bottom, then the direction in which the item in the lower layer of the "pin" - shaped stack is occluded after being tilted by the tilt angle is used as the occlusion direction. The analysis method of the occlusion direction is common knowledge in the art and will not be elaborated here.

The obstructing tilted surface is retrieved by combining the obstructing object, the obstruction direction, and the tilt angle. The method for analyzing and retrieving the obstructing tilted surface is common knowledge to those skilled in the art and will not be elaborated here.
[0095] S63: The area of the obstructing slope surface retrieved from the obstructing object is defined as the target slope area.
[0096] The target tilt area refers to the area of the tilted surface that is obscured. The target tilt area is defined by retrieving the area of the tilted surface from the obscuring object.

[0100] The occlusion position refers to the location of the occlusion slope, which is obtained by retrieving the location of the occlusion slope from the stacked shape.
[0101] S71: Calculate the distance between the occlusion position and the reference output position as the occlusion clearance distance.
[0102] The occlusion clearance distance refers to the distance between the occlusion position and the reference output position. It is calculated by taking the straight-line distance between the occlusion position and the reference output position as the occlusion clearance distance.

[0104] The shielding and cleaning time point refers to the time point when ozone descends to the shielding position and cleans the shielding inclined surface. The shielding and cleaning amount refers to the amount of ozone required to disinfect the target inclined area. The shielding and cleaning amount is matched with the target inclined area from the preset cleaning reference table. Then, the cleaning time of ozone flowing to the shielding position with the shielding and cleaning distance and the shielding and cleaning amount is analyzed. The shielding and cleaning time point is taken from the ozone output time point and the time point after the cleaning time is extended.
[0105] The methods for analyzing cleanup time are common knowledge to those skilled in the art and will not be elaborated here.
[0106] The cleaning comparison table stores the amount of occlusion removal corresponding to different target tilt areas. Under the condition of constant ozone concentration, the larger the target tilt area, the greater the amount of occlusion removal. The parameters in the cleaning comparison table are set in advance by those skilled in the art based on actual conditions and will not be elaborated here.
[0107] S73: The amount of material passing through the pores is obtained based on the occlusion cleaning time point and the pore cleaning time.
[0108] Pore throughput refers to the amount of ozone that passes through marked item 1. Pore throughput is obtained by analyzing the time points of shielding and cleaning and the time of pore cleaning.
[0109] In this embodiment, during the output process, the ozone can be transmitted to the shielding inclined surface through the pores of the marked item 1.
[0110] S74: Calculate the difference between the amount of obstruction clearing and the amount of pore passage as the deviation.
[0111] The deviation amount refers to the difference between the amount of shielding and cleaning and the amount of passage through the pores. The deviation amount is calculated by the difference between the amount of shielding and cleaning and the amount of passage through the pores.
[0112] S75: Updates the reference output speed in response to the deviation.
[0113] A new reference output speed is obtained by matching the deviation from a preset output lookup table. The output lookup table stores the reference output speeds corresponding to different deviations. The larger the deviation, the larger the reference output speed. The parameters in the output lookup table are set in advance by those skilled in the art based on actual conditions and will not be described in detail here.
[0114] Methods for obtaining pore throughput include: S80: Responds to the pore cleaning time and the marked extrusion information to obtain the extrusion time point.
[0115] The compression time point refers to the time point at which the marked item 1 is compressed. The ozone arrival time at the marked position is obtained by calculating the ratio of the reference output distance and the reference output speed. The sum of the arrival time and the pore cleaning time is calculated as the compression time. The compression time point is obtained by combining the ozone output time point and the compression time point.
[0116] S81: Obtain the deviation time by combining the extrusion time point and the occlusion clearing time point.
[0117] Deviation time refers to the duration of the difference between the extrusion time and the obstruction removal time. It is obtained by analyzing the extrusion and obstruction removal time points. In this embodiment, the deviation time can have positive and negative values. When the obstruction removal time point is after the extrusion time point, the deviation time is positive. When the obstruction removal time point is before the extrusion time point, the deviation time is negative.
[0118] S82: When the deviation time is positive, the maximum throughput is taken as the pore throughput.
[0119] When the deviation time is positive, it indicates that the pore throughput is the amount of ozone that passes through the uncompressed marked item 1, and the maximum throughput is taken as the pore throughput.
[0120] S83: When the deviation time is negative, update the pore throughput in response to the marked extrusion information.
[0121] When the deviation time is positive, it indicates that the pore throughput is the combination of the amount of ozone passing through the uncompressed marked item 1 and the amount of ozone passing through the compressed marked item 1. Therefore, a new pore throughput is obtained by matching the marked compression information from the deformation lookup table. The deformation lookup table also stores the pore throughput corresponding to different compression intensities of the marked compression information. With marked item 1 remaining constant, the greater the compression intensity, the smaller the pore throughput; this will not be elaborated upon here.
[0122] S84: Update the reference output speed based on the pore throughput.
[0123] By calculating the average value between the amount of the uncompressed marker 1 passing through the pore and the amount of the compressed marker 1 passing through the pore in update S83, S74 and S75 are re-executed based on the average value to obtain a new reference output speed.
[0124] Also includes: S90: When disinfection is completed based on the transfer window, the marking model is updated by marking the squeezing information.
[0125] When the transfer window is disinfected, the ozone inside the transfer window needs to be extracted to prevent the ozone from being carried out of the transfer window. Then, after the marked item 1 is squeezed, the scanning information is re-acquired to form a new marking model.
[0126] S91: Retrieve the estimated pore path from the marker model.
[0127] The estimated pore path refers to the estimated pore path within the marked item 1 after being compressed, which is obtained by retrieving the estimated pore path from the updated marking model.
[0128] S92: Response to the estimated pore path and tilt angle to obtain the pore residue.
[0129] The diffusion time is the time set by the technicians for the items in the transfer window to complete disinfection and remain stationary while ozone is extracted from the transfer window. The pore inclination is obtained by analyzing the estimated pore path and tilt angle, and the pore residue is matched against a pre-set residue reference table based on the pore inclination.
[0130] The residue control table stores the pore residue corresponding to different pore inclination angles. With a constant ozone content within the pores, a larger pore inclination angle results in faster ozone diffusion and a smaller pore residue. The parameters in the diffusion control table were pre-set experimentally by those skilled in the art based on actual conditions and will not be elaborated upon here.
[0131] S93: Obtain the residual path based on the amount of residual pores.
[0132] The residual path refers to the estimated pore path where the residual pore amount is not zero. The estimated pore path with a non-zero residual pore amount is used as the residual path.
[0133] S94: Obtain the location of residual cleanup through the residual path.
[0134] The residual cleaning location refers to the position of the residual path on the side of the marked item 1 that can be squeezed by the auxiliary device. The residual cleaning location is obtained by projecting the residual path onto the marked item 1. The method for analyzing the residual cleaning location is common knowledge to those skilled in the art and will not be elaborated here.
[0135] S95: Based on the residual amount of pores, the preset auxiliary area, and the residual cleaning position, the residual extrusion force is obtained, and the auxiliary device is controlled to operate at the residual cleaning position and residual extrusion force.
[0136] The auxiliary area is the area of one end of the item that the auxiliary device, set by the technician, is used to squeeze. The residual squeezing force refers to the force required to squeeze out the residual ozone in the marked item 1. The squeezing distance is calculated by taking the shortest distance between the residual cleaning position and the residual path. The residual squeezing force is matched from the residual reference table by the amount of residual pores, the auxiliary area, and the squeezing distance, and the auxiliary device is controlled to operate at the residual cleaning position and the residual squeezing force.
[0137] The residual comparison table also stores the residual extrusion force corresponding to different pore residual amounts, auxiliary areas, and extrusion distances. The larger the pore residual amount and the smaller the auxiliary area, the longer the distance that the pore residual amount needs to be discharged under force. The larger the extrusion distance, the greater the distance that the force is transmitted, and the greater the residual extrusion force. This will not be elaborated here.
