Description

Background Art

[0002] As people's living conditions are getting better and better, their pursuit of life is also getting higher and higher. Besides being satisfied with food, clothing, housing and transportation, more people like to travel. Traveling can not only let people experience and enjoy life and broaden their horizons, but also be a way to relieve the pressure in all aspects of life. There are many transportation methods to choose from when traveling, and airplanes are becoming more and more popular among people. The main reasons for people to choose airplanes are speed, comfort and safety. However, luggage is an essential item for traveling. Most of the existing luggage conveying equipment for airport passengers uses inclined plane turntables for luggage conveying. For inclined plane turntables, luggage slides from the high position to the low position of the inclined plane. Affected by the speed of sliding down from the high position and the gravity of the luggage itself, the kinetic energy of the luggage sliding to the low position is relatively large. After a collision, it will cause an impact on the luggage, easily leading to damage to the luggage and its contents, and will also generate relatively loud noises.

[0003] The inclined plane turntable is a key facility for storing passengers' luggage. Its luggage storage methods are divided into single-layer storage and multi-layer storage. When the number of passengers' luggage increases sharply and the inclined plane turntable tends to be saturated, the multi-layer storage mode will be enabled, that is, continue to stack above the original luggage layer to relieve the pressure brought by the sudden increase in the amount of luggage.

[0004] In view of the limited space in some airports and the relatively short length of the inclined plane turntable, a long inclined plane design is adopted to achieve multi-layer storage of luggage and ensure sufficient luggage storage capacity during large flight operations.

[0005] Therefore, how to provide a device that can relieve the collision between the luggage and the side of the inclined plane turntable of the luggage, prevent the luggage from rushing out of the inclined plane turntable of the luggage, reduce the probability of luggage damage, effectively reduce the collision noise, and determine the current luggage storage mode is an urgent problem to be solved by those skilled in the art.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0031] In addition, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of this disclosure. However, those skilled in the art will realize that the technical solutions of this disclosure may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be employed. In other cases, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of this disclosure.

[0032] The flowchart shown in the accompanying drawings is only an exemplary illustration and does not necessarily include all contents and operations / steps, nor does it necessarily need to be executed in the described order. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined, so the actual execution order may change according to the actual situation.

[0033] First, in the embodiments of this disclosure, a control method for a buffer device of a luggage inclined turntable that can be applied but is not limited to airports is provided. It can also be applied to any luggage transportation scenario. In the embodiments of this disclosure, when it is detected that luggage is imported onto the luggage inclined turntable and there is no luggage in front of the buffer device at the current moment, the buffer device is controlled to extend to a first preset position to wait for the luggage to land, and then it retracts to a second preset position together with the luggage, ensuring that there is a relatively small relative speed between the buffer device and the dropped luggage, reducing the impact speed of the luggage and the buffer device of the luggage inclined turntable, thereby alleviating the collision between the luggage and the side of the buffer device of the luggage inclined turntable, preventing the luggage from rushing out of the buffer device of the luggage inclined turntable, and reducing the probability of luggage damage.

[0034] Figure 1 The following shows a schematic diagram of a control method for a buffer device of a luggage inclined turntable in the embodiments of this disclosure. The method includes the following steps:

[0035] S102, when it is detected that luggage is imported onto the luggage inclined turntable and there is no luggage in front of the buffer device at the current moment, control the buffer device to extend to a first preset position.

[0036] It should be noted that as Figure 2As shown, the luggage in the embodiments of the present disclosure can be any item that needs to be conveyed. For example, it can be personal items checked by airline passengers or different types of goods consigned by express delivery companies. Additionally, in the embodiments of the present disclosure, the luggage inlet conveyor is connected to the luggage inclined turntable. The luggage inlet conveyor will convey the luggage to the luggage inclined turntable. The luggage conveyed by the luggage inlet conveyor slides down from the entrance of the luggage inlet conveyor and contacts the side of the luggage inclined turntable buffer device to form the first layer of luggage. If there is too much luggage conveyed by the luggage inlet conveyor, the luggage inclined turntable will enable a multi-layer storage mode to store the luggage, that is, continue to stack above the original first layer of luggage to form multiple layers of luggage, thereby alleviating the pressure brought by the sudden increase in the amount of luggage; and, the first preset position in the embodiments of the present disclosure is a preset position on the movement path of the buffer device. When the buffer device accurately reaches this position driven by the motor, the pause mechanism is triggered.

[0037] S104, after the luggage lands on the buffer device, control the buffer device to retract to the second preset position.

[0038] It should be noted that the second preset position in the embodiments of the present disclosure is located at the end position of the movement path of the buffer device, that is, the position where the buffer device should stop in the state where it is fully retracted. When the buffer device continues to move and reaches the second preset position, it means that the buffering action has been completed and the buffer device will completely stop. This is to ensure that the buffer device is fully retracted in place and avoid any accidental collisions or damages. Additionally, there is a certain distance between the first preset position and the second preset position in the embodiments of the present disclosure. This distance is to ensure that the buffer device has enough time and space to complete the process from pausing to completely stopping. The specific distance depends on factors such as the speed and acceleration of the buffer device and the falling speed of the luggage.

[0039] A control method for a luggage inclined turntable buffer device provided in the embodiments of the present disclosure. First, when it is detected that the luggage is introduced into the luggage inclined turntable and there is no luggage in front of the buffer device at the current moment, control the buffer device to extend to the first preset position; then, after the luggage lands on the buffer device, control the buffer device to retract to the second preset position. Compared with the related art, when the luggage inclined turntable conveys luggage, the kinetic energy of the luggage sliding down to a lower position is relatively large. After a collision, it will cause an impact on the luggage, easily leading to damage to the luggage, and will also generate a relatively large noise. In the embodiments of the present disclosure, when it is detected that the luggage is introduced into the luggage inclined turntable and there is no luggage in front of the buffer device at the current moment, control the buffer device to extend to the first preset position to wait for the luggage to land, and then retract to the second preset position together with the luggage, ensuring that there is a relatively small relative speed between the buffer device and the falling luggage, reducing the impact speed of the luggage and the luggage inclined turntable buffer device, thereby alleviating the collision between the luggage and the side of the luggage inclined turntable buffer device, preventing the luggage from rushing out of the luggage inclined turntable buffer device, and reducing the probability of luggage damage.

[0040] In some embodiments, in the embodiments of the present disclosure, the buffer device has an extension condition if and only if there is luggage import and there is no luggage in front of the buffer device. After the extension condition of the buffer device is satisfied, the intelligent device control process is immediately started, fully demonstrating its highly intelligent characteristics.

[0041] In some embodiments, the luggage inclined plane turntable buffer device in the embodiments of the present disclosure includes: a luggage import detector, a multi-layer luggage detector. The method further includes: detecting whether there is luggage import through the luggage import detector, and the luggage import detector is arranged at the inlet where the luggage inclined plane turntable buffer device is connected to the luggage import conveyor. If luggage passes through the inlet, the luggage import detector is triggered; detecting whether there is multi-layer luggage through the multi-layer luggage detector, and the multi-layer luggage detector is arranged on the side of the luggage inclined plane turntable buffer device and irradiates the front side of the luggage inclined plane turntable buffer device. If luggage passes through the front side of the luggage inclined plane turntable buffer device, the multi-layer luggage detector is triggered, where the multi-layer luggage is formed by the side contact of the luggage with the first layer of luggage, and the first layer of luggage is formed by the side contact of the luggage with the buffer device; if the multi-layer luggage detector is not triggered, the luggage import detector is triggered and the triggering frequency of the luggage import detector is greater than the preset frequency threshold, it is determined that the luggage inclined plane turntable buffer device stores the luggage in a single-layer storage manner. Specifically, the luggage import detector in the embodiments of the present disclosure is arranged at the inlet of the luggage import conveyor, and can detect in real time whether there is luggage import, ensuring that each operation can be timely responded. The multi-layer luggage detector is arranged on the side of the luggage inclined plane turntable buffer device and irradiates the front side, which can effectively detect whether there is multi-layer luggage and prevent potential safety hazards caused by improper luggage storage; and, by setting the preset frequency threshold, it is possible to judge whether there is single-layer storage luggage or multi-layer storage luggage according to the triggering frequency of the luggage import detector, which helps to improve the accuracy of detection and avoid misjudgment; in addition, the luggage import detector and the multi-layer luggage detector in the embodiments of the present disclosure can be photoelectric sensors, and the photoelectric sensors can quickly capture the luggage import information and immediately notify the control system for corresponding processing, improving the speed and efficiency of the entire process.

[0042] It should be noted that both the acceleration and deceleration of the motor in the embodiments of the present disclosure have the ability of intelligent adjustment. The embodiments of the present disclosure comprehensively consider complex factors such as the physical characteristics of the luggage, the real-time speed of the buffer device, and the mechanical performance of the buffer device, and perform real-time calculation and precise setting of the acceleration and deceleration of the motor. For example, when the sensor feedback indicates that a heavier or larger-sized luggage enters, the embodiments of the present disclosure will automatically adjust the motor to start with a relatively small acceleration to avoid damage to the buffer device caused by an instantaneously excessive impact force; during the extension process of the buffer device, if it is detected that the speed of the buffer device changes or the luggage has abnormal displacement, the acceleration and deceleration of the motor will also be dynamically adjusted accordingly to ensure the smoothness and safety of the extension action of the buffer device.

[0043] In some embodiments, after the luggage lands on the buffer device, the embodiments of the present disclosure control the buffer device to retract to the second preset position, including: after the luggage lands on the buffer device, controlling the buffer device to decelerate and retract to the second preset position at a preset deceleration. Specifically, the embodiments of the present disclosure can adjust the pause time in real time according to the detected luggage dropping speed to achieve the minimum relative speed between the buffer device and the luggage, thereby reducing the impact force and protecting the luggage and the buffer device.

[0044] In some embodiments, when it is detected that the luggage is introduced onto the luggage inclined plane turntable and there is no luggage in front of the buffer device at the current moment, the embodiments of the present disclosure control the buffer device to extend to the first preset position, including: monitoring the torque value when the buffer device starts the extension action; when the torque value of the buffer device is less than the preset resistance threshold, controlling the buffer device to extend to the first preset position. Specifically, the luggage inclined plane turntable buffer device in the embodiments of the present disclosure is closely integrated with the frequency converter and has the ability to perform high-precision and real-time monitoring of the output torque of the frequency converter. During the entire operation cycle of the luggage inclined plane turntable buffer device, starting from when the buffer device receives the extension instruction, the output torque data of the frequency converter is continuously collected to form a dynamic torque data sequence. This sequence accurately reflects the changes in the mechanical environment faced by the device at different action stages. By monitoring the torque value and comparing it with the preset resistance threshold, abnormal situations (such as jamming or encountering excessive resistance) can be detected and processed in a timely manner, avoiding damage to the device due to overload, ensuring that the buffer device operates within the normal resistance range, reducing the impact force on the luggage, and protecting the safety of the luggage.

[0045] In some embodiments, when the torque value of the buffer device in the embodiments of the present disclosure is greater than a preset resistance threshold, the buffer device is controlled to maintain its original state, and the number of failed extension actions is recorded. Specifically, once the embodiments of the present disclosure detect that the torque value is higher than the preset resistance threshold and determine that a large resistance is encountered, an emergency handling procedure is immediately initiated, the current extension action is automatically abandoned, and a motor reverse instruction is quickly issued to drive the device to retract smoothly. During the retraction process, the torque change is continuously monitored to ensure the safety and stability of the retraction action. This mechanism of automatically abandoning extension and retracting can effectively avoid serious consequences such as luggage squeezing, scratching, or even damage caused by forced extension, and maximize the protection of the safety and integrity of passengers' luggage.

[0046] In some embodiments, when the number of failed extension actions of the buffer device in the embodiments of the present disclosure is greater than a preset failure threshold, it is determined that the inclined plane turntable buffer device is in an abnormal state, and an alarm notification is sent to the target maintenance personnel. Specifically, the embodiments of the present disclosure have the function of accurately counting and detailed recording the number of failed actions of the buffer device. Whenever the extension or retraction action of the buffer device fails to be completed smoothly as expected (for example, automatically retracts due to excessive resistance, the action is interrupted due to motor failure, etc.), the current action is automatically marked as a failure, and the time of failure, the specific action link, and relevant sensor data and device status information are recorded in the internal fault record database. Moreover, the embodiments of the present disclosure have preset a threshold for the number of failed actions, which is determined by comprehensively considering various factors such as the reliability index of the device, the busyness of airport luggage handling, and the maintenance response time. When the accumulated number of failed actions reaches or exceeds this threshold, it will be determined that the buffer device is in an abnormal operating state, and the maintenance personnel need to be notified in time for intervention. Once the alarm condition is triggered, the luggage inclined plane turntable buffer device will immediately send an alarm signal, and the maintenance personnel can obtain the alarm signal in the first time and quickly take corresponding maintenance measures.

[0047] In some embodiments, a first limit switch is pre-installed at a first preset position in the luggage inclined plane turntable buffer device of the present disclosure, and a second limit switch is pre-installed at a second preset position. If neither the first limit switch nor the second limit switch is triggered, the luggage inclined plane turntable buffer device is controlled to start the self-resetting function. It should be noted that the two limit switches equipped inside the luggage inclined plane turntable buffer device in the embodiments of the present disclosure are the first limit switch and the second limit switch respectively. These two limit switches can accurately monitor the rotation position of the luggage inclined plane turntable buffer device, provide key position information feedback for the entire action sequence, and constitute one of the basic data sources for intelligent control. In addition, the luggage inclined plane turntable buffer device in the embodiments of the present disclosure has a self-resetting function. After being powered on again due to other factors, if neither the first limit switch nor the second limit switch is triggered, the luggage inclined plane turntable buffer device automatically starts the self-resetting function, and the luggage inclined plane turntable buffer device automatically returns to the non-extended state (the motor rotates forward until the second limit switch is blocked to complete the self-resetting). Moreover, the self-resetting function can return to the normal state without manual intervention after abnormal situations such as power failure of the luggage inclined plane turntable buffer device, further saving maintenance costs and time costs.

[0048] In some embodiments, when it is detected that a piece of luggage is introduced onto the luggage inclined turntable and there is no luggage in front of the buffer device at the current moment, the buffer device is controlled to extend to a first preset position, including: when it is detected that a piece of luggage is introduced onto the luggage inclined turntable and there is no luggage in front of the buffer device at the current moment, after a first preset pause time, the buffer device is controlled to extend to the first preset position and stay at the first preset position for a second preset pause time. It should be noted that the luggage inclined turntable buffer device in the embodiments of the present disclosure has an independent encoder to detect the rotation speed of the luggage inclined turntable. Only when the luggage inclined turntable rotates and meets the extension condition, the buffer device will enter the extension stage. Moreover, the embodiments of the present disclosure also add a safety protection mechanism to the buffer device to prevent someone from accidentally touching the photoelectric sensor at the entrance of the luggage introduction conveyor, resulting in the buffer device extending and causing danger. Specifically, there is a waiting time before the buffer device in the embodiments of the present disclosure extends, that is, after the first preset pause time, the buffer device is controlled to extend to the first preset position. For example, the embodiments of the present disclosure can set the first preset pause time to 0.5 seconds. However, this time is not fixed and can be adjusted arbitrarily according to the actual situation on site (the on-site staff comprehensively considers factors such as the inclination angle of the luggage inclined turntable and the friction coefficient of the luggage inclined turntable to modify the time to ensure a better buffering effect. If the buffer device extends in advance, it may affect the existing luggage on the luggage inclined turntable and cause rubbing with the existing luggage on the luggage inclined turntable); after the first preset pause time, the motor starts to rotate forward under the drive of the intelligent control system, thereby pushing the device to extend. During this process, both the acceleration and deceleration of the motor have intelligent adjustment capabilities. The embodiments of the present disclosure will comprehensively consider complex factors such as the physical characteristics of the luggage, the real-time speed of the luggage inclined turntable, and the mechanical performance of the luggage inclined turntable, and perform real-time calculation and precise setting of the acceleration and deceleration of the motor. For example, when the sensor feedback indicates that a heavier or larger-volume luggage enters, the embodiments of the present disclosure will automatically adjust the motor to start with a relatively small acceleration to avoid damage to the buffer device caused by an instantaneously excessive impact force; during the extension process of the buffer device, if it is detected that the speed of the luggage inclined turntable changes or the luggage has an abnormal displacement, the acceleration and deceleration of the motor will also be dynamically adjusted accordingly to ensure the smoothness and safety of the extension action of the buffer device.

[0049] In some embodiments, after the buffer device extends to the first preset position, the motor pauses running according to the intelligent program instructions to ensure that there is a relatively small relative speed between the buffer device and the dropped luggage, reducing the impact speed of the luggage and the buffer device. For example, the speed of the luggage increases during the dropping process. If the conveyed luggage belongs to light clothing items, since the speed change is relatively stable in a short period of time, the generated impact force is small. In this embodiment of the present disclosure, the second preset pause time can be set to 0.1 second to wait for the luggage to land. If the conveyed luggage belongs to heavy equipment items, since the speed changes violently in a short period of time, the generated impact force is large. In this embodiment of the present disclosure, the second preset pause time can be set to 0.05 second to wait for the luggage to land. It can be seen that this embodiment of the present disclosure dynamically adjusts the preset pause time according to the mass and / or dropping speed of the multi-layer luggage, aiming to reduce the impact speed between the luggage and the buffer device.

[0050] It should be noted that the first preset pause time and the second preset pause time in this embodiment of the present disclosure can be data obtained through intelligent adjustment of the luggage inclined plane turntable buffer device, or experimental data obtained through multiple experiments that conform to the control method of the luggage inclined plane turntable buffer device in this embodiment of the present application, or empirical values obtained based on the experience of those skilled in the art. This embodiment of the present disclosure does not make specific limitations, and those skilled in the art can flexibly set the first preset pause time and the second preset pause time according to the actual situation.

[0051] In some embodiments, as Figure 3 shown, the control method of the luggage inclined plane turntable buffer device in this embodiment of the present disclosure specifically includes:

[0052] S302, determine whether the luggage import detector and the multi-layer luggage detector are triggered.

[0053] S304, if the luggage import detector is not triggered, it means that no luggage is transferred to the buffer device, and the motor does not move. If the luggage import detector and the multi-layer luggage detector are triggered, the first preset pause time before extension is intelligently adjusted to prevent someone from accidentally touching the luggage import detector and causing danger due to the extension of the buffer device.

[0054] S306, control the motor to rotate forward to start the extension action of the buffer device.

[0055] S308, when the buffer device extends to the first preset position, the first limit switch is triggered.

[0056] S310, control the buffer device to wait for the landing of the luggage according to the second preset pause time.

[0057] S312, after the luggage lands, control the buffer device to decelerate and retract to the second preset position at a preset deceleration speed, and the second limit switch is triggered.

[0058] S314, after the buffering action is completed, control the motor to stop rotating.

[0059] In some embodiments, the embodiment of the present disclosure controls the motor to rotate forward to start the extension action of the buffer device, mainly to use the rotation direction of the motor to drive the mechanical structure to complete specific work tasks, that is, to control the buffer device to complete the extension action.

[0060] In some embodiments, as Figure 4 shown, the control method of the torque detection and self-protection alarm mechanism in the embodiment of the present disclosure specifically includes:

[0061] S402, output torque detection to determine the torque value of the buffer device.

[0062] S404, determine whether the torque value is greater than the preset resistance threshold.

[0063] S406, when the torque value of the buffer device is greater than the preset resistance threshold, the self-protection mechanism pre-starts, the landing control buffer device maintains its original state, and the number of failed extension actions is recorded.

[0064] S408, continue to monitor the torque value of the buffer device. When the torque value of the buffer device is less than the preset resistance threshold, the self-protection mechanism pre-closes.

[0065] S410, if the recorded number of failed extension actions is greater than the preset failure threshold (for example, the preset failure threshold can be set to 4, and the embodiment of the present disclosure does not make specific limitations), determine that the buffer device of the luggage inclined plane turntable is in an abnormal state, and send an alarm notification to the target maintenance personnel.

[0066] S412, the maintenance personnel obtain the alarm signal in the first time and quickly take corresponding maintenance measures. After the maintenance is completed, the number of failed extension actions is cleared.

[0067] In some embodiments, as Figure 5 shown, the self-resetting function control method of the buffer device in the embodiment of the present disclosure specifically includes:

[0068] S502, the buffer device of the luggage inclined plane turntable is powered on again.

[0069] S504, determine whether the first limit switch is triggered.

[0070] S506, determine whether the second limit switch is triggered.

[0071] S508. If neither the first limit switch nor the second limit switch is triggered, control the motor to rotate forward.

[0072] S510. If the second limit switch is triggered.

[0073] S512. Control the motor to stop operating.

[0074] In some embodiments, the embodiments of the present disclosure can intelligently judge the extension conditions of the buffer device, the adjustable waiting time, the motor movement parameters, etc., so that the buffer device can cooperate efficiently with the luggage handling process, reduce unnecessary waiting and action time, improve the overall luggage handling speed of the luggage inclined turntable buffer device, and meet the high-flow luggage handling requirements in scenarios such as airports. Moreover, the torque detection and self-protection alarm mechanism in the embodiments of the present disclosure can timely detect abnormal resistance conditions during the operation of the device and take corresponding measures to avoid damage to the buffer device due to forced actions. At the same time, the accurate recording and alarm of action failures help to quickly locate and solve problems, reduce the failure rate of the luggage inclined turntable buffer device, improve the reliability and stability of the luggage inclined turntable buffer device, reduce the shutdown maintenance time, ensure the continuous operation of the luggage handling system. Further, the high reliability and stability of the luggage inclined turntable buffer device reduce the human and material costs brought by fault repair. At the same time, the efficient luggage handling efficiency helps to reduce human input and equipment resource waste, and improve the operation efficiency.

[0075] Based on the same inventive concept, an embodiment of the present disclosure also provides a control device for a luggage inclined turntable buffer device, as described in the following embodiments. Since the principle of solving problems in this device embodiment is similar to that of the above method embodiment, the implementation of this device embodiment can refer to the implementation of the above method embodiment, and the repeated parts will not be described again.

[0076] Figure 6 The following shows a schematic diagram of a control device for a luggage inclined turntable buffer device in an embodiment of the present disclosure. The device includes:

[0077] A first extension module 601, configured to control the buffer device to extend to a first preset position when it is detected that luggage is introduced into the luggage inclined turntable and there is no luggage in front of the buffer device at the current moment;

[0078] A second retraction module 602, configured to control the buffer device to retract to a second preset position after the luggage lands on the buffer device.

[0079] A control device for a buffer device of a luggage inclined plane turntable provided in an embodiment of the present disclosure, through a first extension module, when it is detected that luggage is introduced into the luggage inclined plane turntable and there is no luggage in front of the buffer device at the current moment, controls the buffer device to extend to a first preset position; through a second retraction module, after the luggage lands on the buffer device, controls the buffer device to retract to a second preset position. Compared with the related art, when the luggage inclined plane turntable transfers luggage, the kinetic energy of the luggage sliding down to a lower position is relatively large. After a collision occurs, it will cause an impact on the luggage, easily leading to damage to the luggage, and will generate a relatively large noise. In the embodiment of the present disclosure, when it is detected that luggage is introduced into the luggage inclined plane turntable and there is no luggage in front of the buffer device at the current moment, the buffer device is controlled to extend to the first preset position to wait for the luggage to land, and then retracts to the second preset position together with the luggage, ensuring that there is a relatively small relative speed between the buffer device and the dropped luggage, reducing the impact speed of the luggage and the buffer device of the luggage inclined plane turntable, thereby alleviating the collision between the luggage and the side of the buffer device of the luggage inclined plane turntable, preventing the luggage from rushing out of the buffer device of the luggage inclined plane turntable, and reducing the probability of luggage damage.

[0080] In some embodiments, the buffer device of the luggage inclined plane turntable in the embodiment of the present disclosure includes: a luggage introduction detector, a multi-layer luggage detector. The control device of the buffer device of the luggage inclined plane turntable in the embodiment of the present disclosure further includes: a first detection module, configured to detect whether there is luggage introduced through the luggage introduction detector. The luggage introduction detector is arranged at the inlet where the buffer device of the luggage inclined plane turntable is connected to the luggage introduction conveyor. If luggage passes through the inlet, the luggage introduction detector is triggered; a second detection module, configured to detect whether there is multi-layer luggage through the multi-layer luggage detector. The multi-layer luggage detector is arranged on the side of the buffer device of the luggage inclined plane turntable and irradiates the front side of the buffer device of the luggage inclined plane turntable. If luggage passes through the front side of the buffer device of the luggage inclined plane turntable, the multi-layer luggage detector is triggered, where the multi-layer luggage is formed by the side contact of the luggage with the first-layer luggage, and the first-layer luggage is formed by the side contact of the luggage with the buffer device; a storage mode determination module, configured to determine that the buffer device of the luggage inclined plane turntable stores luggage in a single-layer storage mode if the multi-layer luggage detector is not triggered, the luggage introduction detector is triggered, and the triggering frequency of the luggage introduction detector is greater than a preset frequency threshold.

[0081] In some embodiments, the second retraction module in the embodiment of the present disclosure is further configured to, after the luggage lands on the buffer device, control the buffer device to decelerate and retract to the second preset position at a preset deceleration.

[0082] In some embodiments, the first extension module in the embodiment of the present disclosure is further configured to monitor the torque value when the buffer device starts to extend; when the torque value of the buffer device is less than a preset resistance threshold, control the buffer device to extend to the first preset position.

[0083] In some embodiments, when the torque value of the buffer device in the embodiments of the present disclosure is greater than a preset resistance threshold, the buffer device is controlled to maintain its original state, and the number of failed extension actions is recorded.

[0084] In some embodiments, when the number of failed extension actions of the buffer device in the embodiments of the present disclosure is greater than a preset failure threshold, it is determined that the buffer device of the luggage inclined plane turntable is in an abnormal state, and an alarm notification is sent to the target maintenance personnel.

[0085] In some embodiments, a first limit switch is pre-installed at a first preset position, and a second limit switch is pre-installed at a second preset position in the embodiments of the present disclosure. If neither the first limit switch nor the second limit switch is triggered, the buffer device of the luggage inclined plane turntable is controlled to start the self-resetting function.

[0086] In some embodiments, the first extension module in the embodiments of the present disclosure is further configured to, when it is detected that luggage is introduced into the luggage inclined plane turntable and there is no luggage in front of the buffer device at the current moment, after a first preset pause time, control the buffer device to extend to the first preset position and stay at the first preset position for a second preset pause time.
