The low-temperature plasma nozzle 111 discharges the low-temperature plasma to make the low-temperature plasma fully contact the object 160 to be processed, and kills viruses, particularly RNA and DNA viruses, attached to the surface of the object 160 to be processed.

In some embodiments, the low temperature plasma showerhead 111 may move in a height direction, wherein the height direction may be a direction perpendicular to the base 112. In some embodiments, the low temperature plasma shower head 111 may discharge low temperature plasma at different heights to realize sterilization treatment of regions of different heights of the object to be treated 160. In some embodiments, in order to ensure the user experience of the object to be processed, the low temperature plasma showerhead 111 may be rotated around the object to be processed instead of the pedestal 112, and accordingly, the parameters (such as the rotation speed of the pedestal) and the control method related to the rotating pedestal 112 in the present specification may also be converted into the related parameters and control method of the low temperature plasma showerhead 111.

The base 112 may be a support base for placing the object to be processed 160. In some embodiments, a pressure sensor may be provided in the base 112, and the pressure sensor may detect a pressure signal when the object to be processed 160 is placed on the base 112, thereby determining that the object to be processed 160 has stood on the base 112. In some embodiments, the base 112 may be rotated, and the object to be processed 160 placed/standing on the base 112 may also be rotated, so that the low-temperature plasma discharged from the low-temperature plasma shower head 111 is brought into sufficient contact with a different surface of the object to be processed 160. In some embodiments, when the object 160 to be processed is placed/stood on the base 112, the sensor built in the base 112 may detect the stress signal, and the controller 140 may respond to the stress signal to perform the application method of the low temperature plasma in killing RNA, DNA type viruses.

The controller 140 may be communicatively connected to one or more components of the sterilization apparatus 110 (e.g., the low-temperature plasma head 111, the base 112, the first image pickup device 113, and the second image pickup device 114), and control the operating states of the respective devices. For example, the controller 140 may control the low temperature plasma shower head 111 to discharge the low temperature plasma, thereby performing a sterilization treatment on the object to be processed 160. As another example, the controller 140 may control the rotational speed of the base 112. For another example, the controller 140 may control the movement of the low temperature plasma shower head 111 in the height direction, thereby controlling the height of the low temperature plasma shower head 111. In some embodiments, the controller 140 may be implemented by a computing device (e.g., the controller 140) integrated within or external to the disinfection device 110.

The first image pickup apparatus 113 may be used to acquire a region division image of the object to be processed 160. Wherein the area division image may reflect height information of the object to be processed 160. The region division image may be used to determine a region feature of the object to be processed 160. In some embodiments, the first image pickup apparatus 113 may be positioned above and toward the object to be processed 160, thereby acquiring a region-divided image containing a top contour of the object to be processed 160. The controller 140 may determine the height of the object to be processed 160 to determine the region feature of the object to be processed 160 based on the top contour in the region-divided image and the height of the first image pickup apparatus 113. In some embodiments, the first image pickup apparatus 113 may move in the height direction, thereby acquiring the area division images photographed at different heights. The controller 140 may determine a plurality of regions of the object to be processed 160 based on the region division images photographed at different heights.

The second image pickup apparatus 114 is used to acquire a relative moving image of the object to be processed 160. Wherein the second camera device 114 can move with the base 112. The relative motion image may be used to determine whether a relative displacement occurs when the object to be processed 160 moves along with the base, so that it may be determined whether the sterilization operation is completed.

In some embodiments, the disinfection device 110 may further include a power source (not shown). Wherein the power source may be in communication with an external power source for providing power to the disinfection device 110.

For more details on the determination of whether to complete the sterilization operation at the target sterilization height, reference may be made to step S430 and its associated description. In some embodiments, the execution module 330 may be further configured to, for each of the plurality of disinfection areas, determine whether the object to be processed is in a breath-hold and eye-close state according to a region feature of the face area when the disinfection area is the face area; if the object to be processed is in a state of holding the screen and closing the eyes, controlling the low-temperature plasma spray head to execute a disinfection operation; and if the object to be processed is not in the breath-holding eye-closing state, generating prompt information to prompt the object to be processed to adjust the face posture to be in the breath-holding eye-closing state. For more contents of determining whether the object to be processed is in the breath-holding and eye-closing state, reference may be made to step S610 and its related description. In some embodiments, the execution module 330 may be further configured to determine a sterilization completion of the low-temperature plasma nozzle at a target sterilization height when the low-temperature plasma nozzle performs a sterilization operation at the target sterilization height; and when the disinfection completion degree meets the preset condition, judging that the low-temperature plasma spray head completes the disinfection operation at the target disinfection height. For more on determining the sterilization completion, see fig. 7 and its associated description.

The moving module 340 may be configured to control the low-temperature plasma nozzle to move to a next target disinfection height in the sequence of target disinfection heights and perform a disinfection operation when the low-temperature plasma nozzle completes the disinfection operation at the target disinfection height, so as to kill RNA and DNA type viruses attached to the object to be treated. For more details on controlling the movement of the low temperature plasma showerhead, reference may be made to step S440 and its related description.

It should be noted that the above description of the application system and its module for killing RNA and DNA type viruses by using low temperature plasma is only for convenience of description and should not limit the present specification to the scope of the illustrated embodiments. It will be appreciated by those skilled in the art that, given the teachings of the present system, any combination of modules or sub-system configurations may be used to connect to other modules without departing from such teachings. In some embodiments, the first determining module 310, the second determining module 320, the executing module 330 and the moving module 340 disclosed in fig. 3 may be different modules in a system, or may be a module that implements the functions of two or more modules. For example, each module may share one memory module, and each module may have its own memory module. Such variations are within the scope of the present description.

FIG. 4 is an exemplary flow chart of a method for applying low temperature plasma to kill RNA, DNA type viruses according to some embodiments of the present disclosure. In some embodiments, the process illustrated in fig. 4 may be performed by the controller 140. As shown in fig. 4, the process includes the following steps:

step S410, when the object to be processed is positioned on the base, determining first characteristic information of the object to be processed.

In some embodiments, a pressure sensor may be disposed inside the base. When the object to be processed is placed on the base, the pressure sensor detects the stress signal, and at this time, the controller may determine that the object to be processed is on the base.

The first characteristic information may refer to information reflecting a total release range of the low temperature plasma. Wherein the total release range of the low-temperature plasma should be such that it completely covers the object to be treated. The first characteristic information may contain a height of the object to be processed. For example, when the object to be treated is a user to be sterilized, the first characteristic information may include a user height of the user to be sterilized.

In some embodiments, the first image pickup apparatus 113 may acquire a region division image of the object to be processed 160. The controller 140 may determine the height of the object to be processed 160 based on the region division image. For example, the area-divided image may include the top of the object to be processed, and the controller 140 may determine the distance of the top of the object to be processed 160 with respect to the first image pickup apparatus 113 from the area-divided image, and determine the height of the object to be processed 160 in conjunction with the height of the first image pickup apparatus 113.

In some embodiments, the first characteristic information may further include a type of the object to be processed. For example, the types of the objects to be processed may include living bodies and non-living bodies. It should be understood that when the object to be treated is a living body, important parts of the object to be treated, such as eyes and mouth, should be protected from damage caused by the low-temperature plasma when it is sterilized by the sterilizing device 110. In some embodiments, the first image may be processed based on an object detection algorithm to determine the type of object to be processed.

In some embodiments, the first characteristic information may also be manually labeled by a worker. For example, when an object to be processed is placed on a pedestal, a worker may manually mark and determine the height and type of the object to be processed.

Step S420, determining a target disinfection height sequence based on the first characteristic information.

The sequence of target sterilization levels is a sequence of target sterilization levels. In some embodiments, the sequence of target disinfection heights may be presented in the form of a vector, and each vector element may be one target disinfection height. The sequence of target sterilization heights includes a plurality of target sterilization heights at which the low temperature plasma is discharged by the low temperature plasma showerhead. The low-temperature plasma spray head can sequentially release low-temperature plasma at each target disinfection height based on the target disinfection height sequence.

In some embodiments, the target sterilization height sequence may be determined based on the first characteristic information and a coverage of the low temperature plasma showerhead. The controller may first determine the total height to be disinfected based on the first characteristic information; then determining a disinfection height interval based on the coverage range of the low-temperature plasma sprayer; finally, a sequence of target disinfection heights is determined based on the disinfection height intervals and the total height to be disinfected. Wherein the total height to be sterilized may be a discharge height in a total discharge range of the low-temperature plasma, and the total height to be sterilized may be slightly higher than a height of the object to be sterilized. For example, when the height of the object to be sterilized is 185cm, the total height to be sterilized may be 190cm to achieve full coverage of the object to be sterilized. When the coverage area of the low-temperature plasma nozzle is 10cm, the sterilization height interval can be 10cm, and each target sterilization height can be a central point. That is, the sequence of target disinfection heights may include 19 target disinfection heights of 5cm, 15cm, … …, 185cm, etc.

In some embodiments, the processor may preset a plurality of target sterilization height sequences, each preset target sterilization height sequence corresponding to a range of heights of the object to be treated. The target sterilization height sequence may be determined from a preset target sterilization height sequence according to a specific height of the object to be treated.

In some embodiments, the sequence of target sterilization heights may also be adjusted based on a plurality of sterilization zones of the object to be treated and corresponding zone characteristics such that each sterilization zone contains at least one target sterilization height. Further details regarding the sterilization zone and corresponding zone characteristics can be found in relation to the description of fig. 5.

And step S430, controlling the low-temperature plasma spray head to execute the disinfection operation at the target disinfection height aiming at each target disinfection height in the target disinfection height sequence, and judging whether the disinfection operation at the target disinfection height is finished.

In some embodiments, for each target disinfection height in the sequence of target disinfection heights, the controller 140 may perform a disinfection operation at that target disinfection height based on the disinfection parameters. The sterilization parameters may include parameters affecting the sterilization operation, such as the amount of low-temperature plasma released, the rotational speed of the base, and the like. In some embodiments, the sterilization parameters may be pre-set. In some embodiments, the sterilization parameters may also be adjusted based on the sterilization zone and corresponding zone characteristics. For more on determining the scheduling parameters based on the disinfection zone and the corresponding zone characteristics, reference may be made to fig. 5 and its associated description.

In some embodiments, the controller may determine whether the sterilization operation at the target sterilization height is completed by determining whether the low-temperature plasma covers the object to be treated for one week. For example, the pedestal or the low-temperature plasma shower head may rotate around the object to be treated, and when the pedestal or the low-temperature plasma shower head surrounds the object to be treated by 360 °, it may be determined that the sterilization operation at the target sterilization height has been completed if it is considered that the released low-temperature plasma has already achieved sterilization of the object to be sterilized at the target sterilization height.

In some embodiments, whether to complete the sterilization operation at the target sterilization height may also be determined based on the relative motion image, and further details regarding whether to complete the sterilization operation based on the relative motion image may be found in fig. 7 and its associated description.

In some embodiments, when the sterilization operation at the target sterilization height is not completed, the controller 140 may continue to control the low temperature plasma spray head to perform the sterilization operation at the target sterilization height until completion. For example, when the object to be processed does not rotate 360 ° together with the susceptor due to the movement of the object to be processed on the susceptor, the controller may control the susceptor to continue to rotate so that the object to be processed rotates 360 ° with respect to the low temperature plasma showerhead. For another example, when the object to be processed has a dead space which is not sterilized, the fixed-point sterilization operation can be performed at the dead space by controlling the movable nozzle.

And step S440, when the low-temperature plasma spray head finishes the disinfection operation at the target disinfection height, controlling the low-temperature plasma spray head to move to the next target disinfection height in the target disinfection height sequence and executing the disinfection operation.

In some embodiments, the controller 140 may perform the sterilization operations at the respective target sterilization heights one by one in a preset order in the sequence of target sterilization heights. For example, the preset sequence may be performed from bottom to top, i.e. the sterilization operation is performed 5cm first, and then the sterilization operation is performed 15cm after completion, until all the sterilization operations are completed. Wherein when the low-temperature plasma shower head completes the sterilization operation of the last target sterilization level, it can be regarded that the sterilization operation of the object to be treated has been completed.

In some embodiments, the low temperature plasma showerhead may be movable generally in a direction perpendicular to the pedestal (which may also be referred to as a height direction). When the preset sequence may be performed from the bottom up, the low temperature plasma shower head may be moved in a height direction from a current target sterilization height to another higher target sterilization height.

In some embodiments, steps S430 and S440 may be repeatedly performed until the sterilization operation at the last target sterilization height in the sequence of target sterilization heights is completed to kill RNA, DNA type viruses attached to the object to be treated.

Based on the application method of the low-temperature plasma in killing RNA and DNA type viruses, the target disinfection heights can be divided in a low mode in a self-adaptive mode according to the height of the object to be treated, and omnibearing layer-by-layer disinfection can be carried out. The object to be treated does not need to be placed in a closed container, and the application range of the plasma disinfection technology is expanded.

It should be noted that the description of the above flow is only for illustration and description, and does not limit the application scope of the present specification. Various modifications and changes to the flight control of the process drone may be made by those skilled in the art, guided by the present description. However, such modifications and variations are intended to be within the scope of the present description.

FIG. 5 is an exemplary flow chart of a method of performing a sterilization operation based on sterilization parameters, according to some embodiments described herein. In some embodiments, the flow illustrated in fig. 5 may be performed by the execution module 330.

As shown in fig. 5, the process may include the following steps:

step S510, determining a plurality of sterilization areas and corresponding area features of the object to be treated based on the area division image.

The sterilization area may reflect the composition of the object to be treated in the height direction. For example, when the object to be treated is a human body, the sterilization area may include a foot area, a leg area, a waist area, an abdomen area, a chest area, a back area, a head area, a face area, and the like constituting the human body.

In some embodiments, the controller 140 may perform feature recognition based on the zone segmentation images to determine keypoints for each disinfection zone, and then segment each disinfection zone based on the keypoints. For example, the controller 140 may input the regionalized image into a human recognition algorithm to determine human keypoints (e.g., shoulder, head, neck, palm, leg, foot, etc.) in the regionalized image. Each disinfection area is divided based on key points of the human body. Illustratively, the neck may be taken as a dividing point of the face region and the chest region, and the face region and the chest region may be divided.

The zone characteristics reflect the actual conditions of the corresponding sterile zone. In some embodiments, the zone characteristics may include a range of heights corresponding to the sterile zone and a particular type of the sterile zone. For example, the regional characteristics of the foot region may include a range of heights for the foot region (e.g., 10 cm) and the lowermost foot region being the foot region (i.e., the foot region having a range of 0-10 cm).

In some embodiments, the zone characteristics may include parameters such as surface area, volume, etc. of the object to be treated in the sterilization zone.

In some embodiments, when the object to be treated is a human body, the region characteristic may further include a clothing coverage degree. When the human body is covered by clothes, the acceptance amount of the human body to the low-temperature plasma is higher, and the release amount of the high-temperature and low-temperature plasma can be adjusted. I.e. the degree of clothing coverage, can be used to adjust the low temperature plasma release.

In some embodiments, the region characteristics may also include surface structure complexity. Wherein, the complexity of the surface structure can reflect whether the surface is easy to accumulate the pollutants such as bacteria and the like. The surface structure complexity is related to the base rotation speed. As the surface structure complexity is higher, the lower the temperature plasma needs to be in sufficient contact with the surface, and the lower the pedestal rotation speed needs to be.

Step S520, for each of a plurality of sterilization zones, based on zone characteristics of the sterilization zone, determines sterilization parameters within the sterilization zone.

The sterilization parameters may include a discharge amount of the low temperature plasma showerhead and a rotation speed of the susceptor. In some embodiments, the controller 140 may determine the sterilization parameters based on zone characteristics. For example, the controller 140 may determine the discharge amount of the low temperature plasma based on a preset relationship according to the coverage degree of the laundry in each sterilization area, and the controller 140 may determine the base rotation speed based on a preset relationship according to the complexity of the surface structure.

And step S530, controlling the low-temperature plasma spray head to perform a disinfection operation in the disinfection area based on the disinfection parameters in the disinfection area.

In some embodiments, the controller 140 may generate post-control instructions based on the disinfection parameters for transmission to the corresponding device. For example, the controller 140 may determine the generation power of the low temperature plasma according to the amount of the discharged low temperature plasma and transmit the determined generation power to the low temperature plasma showerhead.

The disinfection parameter-based disinfection operation execution method provided by some embodiments based on the description can adjust the disinfection parameters according to the zone characteristics of the disinfection zone, so that the disinfection operation is more adaptive to the object to be treated.

FIG. 6 is an exemplary flow chart of an inspection method prior to performance of a facial region disinfecting operation, shown in accordance with some embodiments of the present description. In some embodiments, the flow illustrated in fig. 6 may be performed by the execution module 330.

As shown in fig. 6, the process may include the following steps:

step S610, when the plurality of disinfection areas include a face area, determining whether the object to be treated is in a breath-hold and eye-close state according to area features of the face area.

The region feature of the face region may be an image feature of the face region of the object to be processed. For example, the region feature of the face region may be a feature vector of the face region determined based on the region division image, for example. Wherein the feature vector may be determined based on a feature extraction algorithm. In some embodiments, the region features of the face region may include region features of the face region. For example, the region features of the face region may include mouth features, eye features, nose features.

The breath-hold eye-closing state may include an eye-closing state and a breath-hold state. Wherein, the eye-closing state means that the object to be processed closes both eyes. For example, the closed-eye state may include a state in which the object to be treated closes both eyes tightly and both eyes are completely blocked by wearing glasses or eyecups or the like. The breath-hold state may refer to the subject not breathing. For example, the breath-hold state may include a state in which the subject to be treated is tight in the mouth and holds his/her breath, and completely blocks his/her mouth and nose while wearing a mask, a respirator, or the like.

In some embodiments, the breath-hold and eye-close state may be determined by manually labeling the regional features of the facial region.

In some embodiments, the breath-hold and eye-closing state may also be determined by processing the region partitioning image with a trained machine learning model. The controller may input a region division image with a face region of the object to be processed as a machine learning model, and determine whether the object to be processed is in an eye-closing state and a breath-holding state through the machine learning model processing. The output of the model may be represented by a vector, and the vector may include three elements, i.e., a left-eye closed state, a right-eye closed state, and a breath-holding state, where each element value may reflect whether the state is in the state. For example, an element value of 1 may indicate that it is in this state, and an element value of 0 may indicate that it is not in this state.

In some embodiments, the machine learning model may be implemented by an embedding layer as well as a classification layer. Wherein the embedding layer may process the region-divided image to obtain feature vectors of the face region. The classification layer may determine the element values of the respective output vectors from the feature vectors of the face regions. The embedding layer can be a convolutional neural network model, and the classification layer can be a deep neural network model.

In some embodiments, the machine learning model may be determined based on training samples and sample labels. The training sample may be a sample image of a plurality of face regions, and the sample label may be an annotation value indicating whether the sample image is in a corresponding state. For example, when both eyes are closed or a person wearing a sports woman, the element value of the left eye closed state and the right eye closed state in the sample label is 1, and when the subject to be processed closes his mouth and blocks his nostrils or can be determined to be in the breath-hold state according to his spirit, the element value of the breath-hold state in the sample label is 1.

In training, the processor may input training samples into the machine learning model to determine a model output, and iterate parameters of the machine learning model based on the model output and corresponding sample labels to construct a loss function until training is complete. Wherein, the training completion may include the number of iterations exceeding a threshold, the convergence of the loss function, and the like.

In some embodiments, the disinfection device may further comprise a respirator. The to-be-treated object can wear the respirator when being subjected to disinfection treatment, the respirator can protect the mouth and the nose of the to-be-treated object and can be used for breathing at the same time, and then the to-be-treated object can be considered to be in a breath-holding state at the moment. In some embodiments, the respirator may be self-disinfecting. For example, the respirator is internally communicated with a low-temperature plasma nozzle, and a channel capable of releasing low-temperature plasma exists, so that the object to be treated is disinfected when the respirator is taken down.

In some embodiments, the controller may determine whether the subject is in a breath-hold state by determining whether the subject is wearing a respirator based on the regional characteristics of the facial region. That is, when step S610 is executed, it may be determined whether the subject to be treated wears the respirator and is in the eye-closing state according to the region characteristics of the face region; and if the to-be-processed object is in the eye-closing state after wearing the respirator, judging that the to-be-processed object is in the breath-holding eye-closing state.

In some embodiments, the controller may also determine whether the subject is wearing a ventilator based on the usage status of the ventilator. For example, when the subject breathes through the ventilator, the relevant sensor (e.g., a carbon dioxide detector) may detect the breathing behavior, and it may be determined that the subject is wearing the ventilator.

In some embodiments, the processor may also process the regionalized images through a trained machine learning model to determine whether the subject is wearing a ventilator. Wherein the output vector of the machine learning model may include an element of wearing a ventilator. Correspondingly, the training label can also include the element and perform labeling and training.

Step S620, when the object to be processed is in a state of holding the screen and closing the eyes, controlling the plasma nozzle to execute a disinfection operation.

When the object to be treated is in the breath-holding eye-closing state, the object to be disinfected can know that sensitive organs are protected, and then the disinfection operation can be normally executed. For more on performing the sterilization operation, reference may be made to fig. 5 and its associated description.

In step S630, when the object to be processed is not in the breath-hold and eye-close state, prompt information is generated to prompt the object to be processed to adjust the face pose to be in the breath-hold and eye-close state.

When the subject to be treated is not in the breath-hold and eye-close state, sensitive organs such as eyes and nostrils of the subject to be treated may be exposed to the low-temperature plasma along with the execution of the sterilization operation, thereby causing damage. When the object to be treated is not in the breath-holding eye-closing state, the disinfecting operation may be stopped, and prompt information may be generated to prompt the object to be treated to adjust the face posture to be in the breath-holding eye-closing state.

In some embodiments, this flow may be performed as appropriate. For example, the flow may be performed in real time during the sterilization operation to avoid that the object to be treated is not in the breath-hold and eye-close state during the sterilization operation. For another example, the flow may be performed before the sterilization operation of the face area is performed to ensure that the object to be treated is in a breath-hold and eye-close state while the sterilization operation of the face area is performed.

Fig. 7 is an exemplary flow chart of a sterilization completion determination method according to some embodiments described herein. In some embodiments, the flow illustrated in fig. 7 may be performed by the execution module 330.

As shown in fig. 7, the flow includes the following steps.

Step S710, for each target sterilization level, acquiring a relative motion image sequence of the plasma nozzle when performing a sterilization operation at the target sterilization level.

The relative moving image sequence may be a sequence of images of the object to be processed periodically acquired by the second image pickup apparatus rotating with the base. In some embodiments, the acquisition period of the relative moving image may be determined according to a period of rotation of the base, wherein the period of rotation may be determined based on a rotation speed of the base. For example, the cycle of one rotation of the base is 5s, and according to the preset rule, it may be determined that the acquisition cycle may be 1s, that is, one relative moving image is captured every 1s, and 5 relative moving images may be acquired by one rotation of the base.

Step S720, calculating a movement amplitude vector of the object to be treated at the target sterilization height from each relative moving image in the sequence of relative moving images.

The movement magnitude vector may reflect a vector of movement of the object to be processed with respect to the base. The motion magnitude vector may include a plurality of elements, each element corresponding to a relative motion image, and each element value may characterize a motion magnitude. For example, for a relative motion image sequence including 5 relative motion images, the corresponding motion magnitude vector may be (0,0,1,2,3), where 0 indicates that the object to be processed remains stationary with the base target object in the second graph, and 1/2/3 indicates that the object to be processed has moved by different magnitudes, respectively. In some embodiments, the element values may be determined from the angle of relative movement. For example, each time the object to be processed is rotated 18 ° with respect to the base, the corresponding element value is increased by 1.

It should be understood that the base, the second image pickup apparatus, and the object to be processed are relatively stationary in view of the fact that the second image pickup apparatus can rotate with the base. Correspondingly, the movement of the object to be processed relative to the base is also relative to the second imaging apparatus. In some embodiments, the controller may determine the moving amplitude of the object to be processed according to an angle change value of the object to be processed in the relative moving image. That is, the controller may determine the magnitude of movement in two adjacent relative moving images by comparing the angles of the object to be processed in the relative moving images.

And step S730, determining the disinfection completion degree of the target disinfection height according to the movement amplitude vector.

In some embodiments, the controller may determine a total movement amplitude of the object to be processed based on the movement amplitude vector. Wherein, the total moving amplitude can refer to the total moving amplitude of the object to be treated at a certain target disinfection height relative to the base. In some embodiments, the total movement amplitude may be the sum of the absolute values of the individual movement amplitudes.

In some embodiments, the controller may subtract the total movement amplitude from the rotation angle of the base to determine the sterilization completion. For example, a 360 rotation of the base is 1 and a movement of 0.05 can be represented for each 1 unit of movement. The degree of completion is 0.7 for a relative moving image sequence including 5 relative moving images.

It should be understood that, in order to secure the safety of the object to be treated, the controller may detect the sterilization completion of the target sterilization height after the base has rotated one revolution. And when the disinfection completion degree of the target disinfection height is smaller than a preset completion degree threshold value, judging that the disinfection completion degree does not meet a preset condition, and re-executing the disinfection operation of the target disinfection height. Wherein the threshold value of the degree of completion can be determined according to the actual sterilization requirements. For example, the completion threshold may be 0.9.

In some embodiments, the disinfection apparatus may further comprise a third camera device. The third camera equipment can not rotate along with the base and faces the object to be processed with the current target disinfection height, and the temperature image of the object to be processed is obtained. Wherein the third camera device may be an infrared temperature-sensitive camera, and the temperature image may contain temperature information of the object.

In some implementations, the controller can determine the disinfection effect of multiple areas of the object to be treated based on the temperature image. When the temperature of the object to be processed in the temperature image is close to the room temperature, it can be determined that the object to be processed is less affected by the low-temperature plasma, which indicates that the low-temperature plasma has a lower concentration and a poorer disinfection effect. The temperature of the object to be treated is close to the temperature of the low-temperature plasma, which means that the plasma concentration in the area is higher and the disinfection effect is better.

In some embodiments, the sterilization completeness may be adjusted based on the sterilization effect. And adjusting the disinfection completion degree of the target disinfection height corresponding to each area of the corresponding object to be treated according to the temperature image. For example, when a certain area is poor in sterilization effect, the sterilization completion of the target sterilization height corresponding to the area may be reduced by 0.1.

In some embodiments, the disinfection device may further comprise a movable nozzle. The controller can control the movable nozzle to move to an area with poor disinfection effect to carry out fixed-point disinfection operation. After the movable nozzle performs the fixed-point disinfection operation, the disinfection completeness deducted due to poor disinfection effect can be recovered.

Based on the sterilization completion determining method shown in some embodiments of the present specification, it can be ensured that the object to be treated completes the sterilization operation.
