Description

Technical Field

[0001] The present invention relates to the technical field of airport baggage conveying, and more particularly to a baggage handling system and method based on planar magnetic levitation. Background Art

[0002] Airport baggage handling systems are essential core facilities for air transportation, responsible for the automated handling of passenger baggage from check-in to loading. Comprised of check-in, security screening, conveying, sorting, storage, transfer, and loading, the system ensures efficient and accurate baggage delivery to its destination through the coordinated operation of mechanical conveying equipment and information management systems. Its performance directly impacts flight punctuality, passenger satisfaction, and airport operational efficiency. With the continued growth of air passenger traffic, traditional baggage handling systems are increasingly experiencing limitations in terms of speed, reliability, and flexibility.

[0003] The baggage handling systems currently used by airports rely primarily on mechanical conveying equipment and sensor networks. In the conveying process, belt conveyors and roller lines are the mainstream technologies, using motors to transport baggage. In the sorting process, equipment such as cross-belt sorters and flip-plate sorting systems classify baggage based on flight information. While these systems can meet basic needs, they present numerous problems in actual operation: Mechanical components can experience severe wear and tear over time, leading to unstable conveying and noise pollution; sorting speeds are limited, making it easy for baggage to slip or be sorted incorrectly during high-speed operation, making accurate baggage tracking difficult; and the system relies on a large number of sensors working together, which not only increases wiring complexity but also increases failure rates and maintenance costs. Furthermore, fixed conveying paths are difficult to adapt to dynamic adjustment needs, and energy efficiency needs to be improved.

[0004] Existing magnetic levitation technology has begun to be applied to planar conveyor systems. While these systems address the complex structures and high friction losses of traditional linear motor systems, they are primarily designed for general logistics scenarios and lack specific optimization for airport baggage handling. Consequently, they cannot meet the high-efficiency, high-reliability, and intelligent baggage handling system requirements of modern airports.

[0102] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the invention and are not intended to limit the invention.

[0103] To address the problems existing in existing airport baggage handling systems, such as severe mechanical wear, low sorting efficiency, poor path flexibility, and insufficient functional integration, this paper proposes a baggage handling system and corresponding processing method based on planar magnetic levitation technology to achieve efficient, intelligent, and highly reliable baggage conveying and sorting.

[0104] Figure 1 The principle block diagram of a baggage handling system based on planar magnetic levitation according to an embodiment of the present invention is disclosed. Figure 1 As shown, the present invention proposes a baggage handling system based on planar magnetic levitation, comprising a plurality of mover modules 10, a plurality of stator modules 20, a baggage feature recognition device 30 and a control system 40:

[0105] The stator modules 20 are used to construct and pave the luggage conveying plane and generate a controllable electromagnetic field;

[0106] The plurality of mover modules 10 are used to carry luggage and interact with the electromagnetic field of the stator module 20 to achieve contactless suspension and driving;

[0107] The baggage feature recognition device 30 is used to obtain baggage information and transmit it to the control system 40;

[0108] The control system 40 is connected to the baggage feature recognition device 30 and the stator module 20, respectively, and plans the motion path of the mover module 10 and the baggage sorting logic based on the baggage information. The motion of the mover module is controlled by dynamically adjusting the electromagnetic field parameters of the stator module 20.

[0109] The present invention proposes a baggage handling system based on planar magnetic levitation. By combining magnetic levitation with intelligent control algorithms, it constructs an efficient conveying system optimized for airport baggage handling, significantly improving baggage handling efficiency, reducing operating costs, and providing reliable technical support for airport intelligent upgrades.

[0110] In this embodiment, the baggage feature recognition device 30 is the "intelligent eye" of the magnetic levitation baggage handling system. It uses high-precision three-dimensional sensing technology to achieve all-round collection of baggage information, providing key data support for subsequent automated sorting and route planning.

[0111] More specifically, the baggage feature recognition device 30 includes at least one depth camera installed at a preset position of the check-in counter;

[0112] The depth camera collects baggage information in real time and sends it to the control system 40. The baggage information includes the three-dimensional size information (length, width, height) and spatial position information (center coordinates, edge coordinates, etc.) of the baggage.

[0113] The control system 40 determines whether the luggage meets the consignment specifications based on the luggage information collected by the depth camera.

[0114] Furthermore, as shown in FIG5 and FIG6, a baggage feature recognition device 30 is installed above the baggage check-in area (ie, electronic scale conveyor) of the check-in counter so that its field of view completely covers the entire check-in area.

[0115] The depth camera is fixed to the ceiling or dedicated support structure through a mounting frame or bracket, and the camera's optical axis must be perpendicular to the baggage check-in plane to ensure that the top contour and overall shape characteristics of the baggage can be accurately captured.

[0116] The depth camera collects the 3D point cloud data of the luggage in real time and calculates the luggage's location information, including spatial parameters such as the luggage's center coordinates and edge coordinates, through point cloud processing algorithms such as point cloud filtering and segmentation.

[0117] Based on the above position information, the control system 40 determines whether the baggage is placed in the preset check-in area and whether the position of the baggage on the conveyor belt meets the subsequent sorting requirements;

[0118] The control system 40 obtains the three-dimensional size data of the luggage and analyzes it to obtain the size measurement results of the luggage, including the length, width and height parameters;

[0119] The control system 40 compares the above-mentioned size measurement results with the preset luggage size standard to determine whether the luggage is overlong:

[0120] When either the length or width of a piece of luggage exceeds a set threshold (e.g. 1000mm), the luggage is identified as oversized and a preset reminder mechanism (such as an audible and visual alarm, screen prompt, etc.) is triggered.

[0121] In this embodiment, the intelligent identification and dynamic tracking technology of the moving module 10 is the core innovation of this system. Through the coordinated effects of coding identification, real-time positioning and luggage information, accurate control of the entire baggage transportation process is achieved.

[0122] More specifically, the mover module 10 is provided with a unique identification code;

[0123] Optionally, the unique identification code is solidified on the surface of the module in the form of an RFID tag or a QR code;

[0124] The stator module 20 has a built-in coding recognition unit and a position sensor, wherein:

[0125] The coding identification unit may adopt a contactless radio frequency identification technology or an optical identification device for reading the unique identification code of the mover module 10 in real time;

[0126] The position sensor may be a high-precision Hall sensor or a laser rangefinder, which is used to detect the real-time position information of the mover module 10 on the baggage conveying plane;

[0127] The control system 40 dynamically associates the unique identification code and real-time location information of the moving module 10 with the corresponding luggage information, thereby realizing full-process tracking and management of the luggage during transportation.

[0128] Baggage information is entered by the baggage feature recognition device 30 during check-in. The control system 10 builds a dynamic mapping database of the unique identification code of the mover module, real-time location information, and baggage information. During check-in, the baggage information is bound to the mover module code. Position sensors are used to update the mover module coordinates in real time. This binding relationship enables full baggage tracking and management from check-in to sorting.

[0129] Furthermore, the control system 40 is configured with a flow monitoring algorithm to implement intelligent scheduling of the moving modules based on the baggage flow, which is achieved through the following steps:

[0130] The control system 40 monitors in real time the number of baggage tags entered into the system per unit time as a baggage flow parameter, and dynamically adjusts the motion parameters of the moving submodule according to the monitoring result.

[0131] More specifically, the control system 40 monitors in real time the number of baggage tags entered into the system per unit time, using the number as a baggage flow parameter. The control system dynamically adjusts the motion parameters of the mover module based on the baggage flow parameter, including a reference speed and acceleration.

[0132] The control system uses a fuzzy logic controller to achieve adaptive adjustment of motion parameters. For example, the input baggage flow parameters include: area load rate (0-100%); flight remaining time (0-120 minutes); the output motion parameters include: reference speed (0.5-5m / s); acceleration (0.1-2m / s²):

[0133] When the regional load factor increases and the remaining flight time decreases, the base speed and acceleration are increased simultaneously;

[0134] When the regional load factor decreases and the flight has sufficient remaining time, the base speed and acceleration are reduced simultaneously;

[0135] The control system 40 performs dynamic adjustments through real-time monitoring of baggage flow, so that the conveying capacity of the mover module adapts to changes in baggage flow, optimizes system energy consumption while ensuring baggage handling efficiency, and realizes intelligent operation and management of the magnetic levitation baggage handling system.

[0136] The mover module 10 and stator module 20 are the core moving components of this magnetic levitation baggage handling system, enabling contactless levitation and precise driving. The following details the specific structure and operating principles of these two key modules.

[0137] The mover module 10 provides load-bearing support for the luggage. By distributing a number of mover modules 10 (the number is configured according to demand, such as 4, 6, etc.) at the bottom of the luggage or at the corresponding support positions, the mover modules 10 work together to hold the luggage and achieve stable load and transportation of the luggage in the conveying system.

[0138] Figure 2a A first schematic diagram of a moving module and a luggage carrying method according to an embodiment of the present invention is disclosed. Figure 2a As shown, the supporting method of the movable submodule 10 and the luggage 70 is as follows: four movable submodules 10 are respectively arranged at the four corners of the luggage 70 (or corresponding support points). Through the joint action of the four movable submodules 10, a single piece of luggage 70 is supported from the bottom of the luggage on all sides, thereby achieving the lifting and transportation of the luggage 70 during the conveying process.

[0139] Figure 2b A second schematic diagram of a moving module and a luggage carrying method according to an embodiment of the present invention is disclosed. Compared with FIG. 2a , FIG. Figure 2b As shown, two new moving modules are installed below the luggage. These six moving modules collectively support a single piece of luggage 70. Through the coordinated cooperation of multiple moving modules, the luggage 70 is lifted from multiple points below, adapting to the carrying and transportation requirements of luggage of different sizes and weights in baggage transportation scenarios.

[0140] In this embodiment, the mover module 10 is a passive magnetic suspension component with a permanent magnet integrated therein, and can achieve suspension and movement on the electromagnetic field generated by the transmission plane module.

[0141] In this embodiment, the mover module 10 includes a permanent magnet unit, a conductive winding unit, an intelligent control unit, and a protective housing:

[0142] The permanent magnet unit is arranged at the bottom of the mover and is used to interact with the electromagnetic field of the stator module to achieve contactless suspension;

[0143] The conductive winding unit is composed of a three-axis orthogonal induction coil and is arranged above the permanent magnet unit to sense the magnetic field change of the stator unit and generate a Lorentz force to drive the mover module to move;

[0144] The intelligent control unit is arranged at the center of the moving module and is used to process control signals and adjust the motion state of the moving module;

[0145] The protective shell wraps the above-mentioned units and forms a luggage carrying surface.

[0146] More specifically, the permanent magnet unit is made of high-performance permanent magnet material and arranged in a specific Halbach array form to generate a high-intensity and well-directional magnetic field for interacting with the electromagnetic field of the stator module, enabling the mover module to achieve contactless suspension and driving.

[0147] The conductive winding unit uses a three-axis orthogonal induction coil (Φ0.5mm enameled wire) to enable the mover module to accurately sense the magnetic field changes of the stator module, achieving efficient drive in three-dimensional space and meeting the needs of luggage transportation on complex paths.

[0148] The conductive winding unit is used to interact with the electromagnetic field generated by the stator module to form a Lorentz force that drives the mover module to move.

[0149] When the coil of the stator module 20 is energized to generate a magnetic field, the magnetic field interacts with the conductive winding to generate an electromotive force, thereby driving the mover module 10 to move within a plane, thereby achieving precise control of the movement of the mover module 10 .

[0150] The protective shell has good strength, rigidity and wear resistance, and its surface is specially treated to provide appropriate friction to ensure stable placement and smooth sliding of the luggage.

[0151] Furthermore, the intelligent control unit includes a microprocessor, a memory and a communication module:

[0152] The microprocessor is used to execute a preset control algorithm, process signal data from the stator module 20 or its own sensors, and calculate and generate motion state adjustment instructions for the mover module 10. The motion state of the mover module 10 includes speed, acceleration, etc.;

[0153] Memory, used to store control programs, operating parameters and status data;

[0154] The communication module is used to implement real-time data interaction with the stator module 20 , receive control instructions, and feedback status information of the mover module 10 .

[0155] Figure 3 A schematic diagram of a baggage conveying plane and a baggage check-in process according to an embodiment of the present invention is disclosed. Figure 3 As shown, the mover module 10 carries the luggage 70 and moves on the luggage conveying plane 80 .

[0156] Multiple stator modules are modularly assembled to create the baggage conveyor plane 80, offering flexible adaptability. Users can freely combine and expand the system based on production line scenarios, eliminating the need for complex supporting mechanisms and significantly simplifying the mechanical design of the production line. The system can also be freely arranged into any shape as needed, adapting to multiple sizes and load capacities to meet diverse application needs.

[0157] Next, the specific structure and working principle of the stator module 20 are introduced.

[0158] In this embodiment, the stator module 20 includes a coil assembly, a power electronic component, a motion control unit, and a position sensor;

[0159] The coil assembly is used to generate a controllable electromagnetic field to achieve suspension and driving of the mover module 10;

[0160] The power electronic component is electrically connected to the coil group and is used to convert the input current into high-frequency alternating current, adjust the parameters of the high-frequency alternating current and output it to the coil group;

[0161] The motion control unit is connected to the power electronic component and is used to dynamically adjust the direction and magnitude of the current according to the control instructions to control the motion trajectory of the mover module 10;

[0162] The position sensor uses a non-contact detection method to obtain the position information of the mover module 10 in real time.

[0163] More specifically, the coil group uses a multi-layer printed circuit board (PCB) coil or a wound coil, which generates a uniform and adjustable electromagnetic field when energized, interacting with the permanent magnet unit in the mover module 10 to achieve suspension and drive of the mover module 10.

[0164] The layout and dimensions of the coil assembly are precisely designed to ensure that the magnetic field distribution meets the requirements of suspension and motion control.

[0165] More specifically, the power electronic components, including inverters, rectifiers, and power amplifiers, are used to convert the input current into high-frequency alternating current suitable for the operation of the coil group, and accurately control the high-frequency alternating current parameters (current magnitude and frequency), thereby adjusting the magnetic field strength and rate of change to adapt to the different motion state requirements of the mover module.

[0166] More specifically, the motion control unit is used to generate a driving magnetic field to enable the mover module 10 to achieve precise motion control within the baggage conveying plane.

[0167] The motion control unit can generate a rotational and translational magnetic field within the baggage conveying plane by changing the direction and magnitude of the current in the coil group, guiding the mover module to move along a predetermined path and achieving speed and acceleration regulation.

[0168] In order to meet the dynamic change requirements of the airport transportation path, in this embodiment, the stator module 20 adopts a modular splicing design;

[0169] Adjacent stator modules 20 are connected via standardized interfaces, and the baggage conveying plane is topologically reconfigured according to the requirements of different sorting scenarios.

[0170] More specifically, the stator module 20 utilizes a modular, spliced ​​structure. Each module is tightly connected via mechanical interfaces to form a unified baggage conveyor surface. This design allows the system to flexibly adjust the shape and size of the conveyor surface based on actual needs, facilitating expansion and layout optimization.

[0171] Adjacent stator modules 20 are spliced ​​together through high-precision mechanical interfaces.

[0172] The mechanical interface is designed with precise positioning and fastening devices to ensure that the modules fit tightly together without gaps, thereby ensuring that the mover module 10 can run smoothly on the baggage conveying plane after splicing without being affected by the module joints.

[0173] The mechanical interface has a certain degree of flexibility and can adapt to slight differences in thermal expansion and contraction between modules, as well as slight mechanical deformation, thereby improving the stability and reliability of the entire system and extending the service life of the equipment.

[0174] Furthermore, the stator module 20 is provided with a standardized power interface and communication interface;

[0175] The power interface adopts a cascade power supply design to achieve power connection between adjacent stator modules and external power access;

[0176] The communication interface is used to realize the communication connection between the stator module and the control system;

[0177] The power interface and the communication interface are electrically connected between the stator modules through a hidden channel.

[0178] Each stator module 20 is equipped with a standardized power interface for connecting to an external power source.

[0179] The power interface features overcurrent, overvoltage, and short-circuit protection, ensuring the module can safely shut down in abnormal situations, protecting equipment and personnel. When multiple modules are connected, the power interface supports cascade power supply between modules, connecting adjacent modules via adapters to ensure power supply across the entire transmission plane.

[0180] The stator module 20 exchanges data via high-speed communication interfaces, such as industrial Ethernet or fieldbus interfaces. These interfaces support multiple communication protocols, such as PROFINET and EtherNet / IP, enabling efficient communication with control systems and other devices, enabling centralized monitoring and management of the entire conveyor system.

[0181] During mechanical splicing, the communication cables and power cables between the stator modules 20 are connected through hidden channels, keeping the conveying surface clean and flat. This integrated design simplifies system wiring, facilitates installation and maintenance, and improves the overall performance of the system.

[0182] As the core power unit, the stator module 20's operating status directly affects system reliability and efficiency. To achieve refined operation and maintenance management, the stator module 20 integrates an intelligent monitoring unit to form a closed-loop monitoring system.

[0183] Furthermore, the stator module 20 further includes an intelligent monitoring unit, which includes at least a temperature sensor and a current and voltage sensor;

[0184] The temperature sensor is used to monitor the temperature data of the internal components of the stator module in real time;

[0185] The current and voltage sensor is used to monitor the working current and voltage parameters of the coil group in real time;

[0186] The control system realizes real-time monitoring, abnormality warning and adjustment control of the working state of the stator module by analyzing the temperature, current and voltage data.

[0187] Through real-time collection and intelligent analysis of multi-dimensional data such as temperature, current, and voltage, the intelligent monitoring unit builds a health monitoring system for the stator module 20. This not only provides early warning of potential faults (such as overheating and abnormal current), but also provides data support for the control system to dynamically optimize operating parameters, significantly improving the stability and operation and maintenance efficiency of the magnetic levitation system.

[0188] In a baggage handling system based on planar magnetic levitation, the functions of the mover module can be deeply integrated. In addition to carrying and conveying, the magnetic levitation characteristics can also be used for weighing. Since each mover module can also be used as a high-precision scale, there is no need for an electronic scale at all.

[0189] In this embodiment, the control system is configured as follows:

[0190] Real-time collection of coil current parameters of the stator module and suspension gap data of the mover module;

[0191] Based on a preset electromagnetic force calculation model, the electromagnetic force value required to maintain the current levitation is calculated according to the coil current parameters and the levitation gap data;

[0192] The electromagnetic force value is converted into the luggage weight value by using the established electromagnetic force-mass conversion relationship.

[0193] More specifically, when luggage is placed on the mover module, it changes the force balance of the mover module, thereby affecting the electromagnetic force required to maintain suspension.

[0194] The weight of the luggage can be calculated based on the conversion relationship between electromagnetic force and load mass. The control system, based on the intrinsic characteristics of the magnetic levitation system, achieves weighing by precisely measuring the electromagnetic force required to maintain each mover's levitation.

[0195] The electromagnetic force calculation model and the electromagnetic force-mass conversion relationship are as follows: ; Where F is the suspension force (N), m is the load mass (kg), g is the acceleration due to gravity (9.81m / s²), k is the electromagnetic coefficient (N·m² / A²), I is the coil current (A), and d is the suspension gap (m).

[0196] In this embodiment, by integrating electromagnetic force monitoring and mass conversion logic, the mover module, while carrying luggage, leverages the relationship between coil current, suspension gap, and electromagnetic force to accurately obtain the luggage weight without the need for an additional electronic scale. This achieves the integrated integration of conveying and weighing functions, simplifies the system hardware configuration, and improves the intelligence and efficiency of the luggage handling process.

[0197] In order to achieve accurate sorting of luggage by flight, in this embodiment, a sorting mechanism based on electromagnetic field control is constructed with the help of the coordination of the control system 40, the stator module 20 and the mover module 10.

[0198] In this embodiment, the control system 40 generates tilt control instructions based on the flight information of the luggage;

[0199] The stator module 20 responds to the tilt control instruction and adjusts the current parameters of the coil group at the corresponding position to establish an electromagnetic field effect;

[0200] The mover module 10 generates a controlled tilting motion under the action of the electromagnetic field;

[0201] The tilting action is used to guide the luggage to a designated sorting chute to complete the sorting operation according to flight information.

[0202] In this embodiment, the electromagnetic control characteristics of the magnetic levitation system are utilized to accurately guide the luggage into the corresponding flight sorting slide without the need for complex mechanical structures, efficiently realize automatic sorting according to flight information, and enhance the intelligent sorting capability of the baggage handling system.

[0203] In this embodiment, the planar magnetic levitation-based baggage handling system further includes:

[0204] A power supply cable 62 is connected to the power interface of each stator module 20 to provide working power to the stator module 20;

[0205] The communication cables 61 are connected to the communication interfaces of the stator modules 20 and the control system 40 respectively, and are used to implement data communication between the stator modules 20 .

[0206] In this embodiment, the planar magnetic levitation-based baggage handling system further includes:

[0207] The mounting bracket 50 provides a rigid support reference surface for the stator module array, ensuring the flatness and parallelism requirements between the modules.

[0208] The mounting bracket 50 not only ensures stable installation and precise positioning of the stator module, but also enables flexible expansion of the system through its modular structure, providing a reliable physical support platform for the engineering application of the planar magnetic levitation baggage handling system.

[0209] In summary, the planar magnetic levitation baggage handling system proposed in this invention uses a modular stator to construct a flexibly expandable baggage conveying plane. The electromagnetic interaction between the mover and stator modules enables contactless levitation, drive, and precise control of baggage. It integrates multiple functions such as baggage feature recognition, full-process tracking, intelligent scheduling, weighing, and sorting, significantly improving the efficiency, flexibility, and intelligence level of airport baggage handling.

[0210] Using the above-mentioned baggage handling system based on planar magnetic levitation, the present invention also proposes a baggage handling method based on planar magnetic levitation.

[0211] Figure 4 The following discloses a step diagram of a baggage handling method based on planar magnetic levitation according to an embodiment of the present invention. Figure 4 As shown, the present invention proposes a baggage handling method based on planar magnetic levitation, comprising the following steps:

[0212] Step S1: Obtain baggage information to determine whether the baggage meets the consignment regulations;

[0213] Step S2: uniquely bind the baggage information that meets the specifications to the moving module, plan the moving module's movement path and baggage sorting logic based on the baggage information, and generate the optimal transportation path;

[0214] Step S3: Based on the optimal conveying path, control the moving module to convey the luggage.

[0215] When determining the optimal delivery path, intelligent planning is performed based on a multi-factor weighted decision model, the comprehensive score of each candidate path is calculated, and the path with the highest comprehensive score is selected as the optimal delivery path.

[0216] The following judgment factors and their impact on baggage handling efficiency and system performance are mainly considered, and corresponding weights are set.

[0217] In this embodiment, the judgment factors include time cost (t), energy cost (E), congestion index (D), and priority weight (P):

[0218] Time cost primarily reflects the time required to transport baggage from its origin to its destination, which is directly related to baggage handling efficiency and flight punctuality. Shorter transport times ensure that baggage arrives at its designated location faster, reducing passenger waiting time and improving airport operational efficiency.

[0219] Energy consumption is related to the energy consumed during baggage transportation. Reducing energy consumption by optimizing routes not only reduces operating costs but also helps airports achieve their environmental goals of energy conservation and emission reduction.

[0220] The congestion index reflects the degree of congestion on the transport route. Avoiding congested areas can prevent delays and backlogs in baggage transport, ensuring smooth and stable transport and improving system reliability.

[0221] Priority weights are determined primarily based on the urgency and importance of the flight. For example, luggage belonging to an upcoming flight or important passengers will be given a higher priority weight to ensure they are delivered and handled first.

[0222] Optionally, the weight of time cost α=0.35, the weight of energy cost β=0.25, the weight of congestion index γ=0.2, and the weight of priority weight δ=0.2.

[0223] Furthermore, in different baggage handling scenarios, the weight parameters of the multi-factor weighted decision model are dynamically adjusted according to actual conditions and needs:

[0224] For example, during peak flight takeoff and landing periods, baggage handling volume increases significantly.

[0225] At this time, the weight of the time cost should be appropriately increased (for example, to 0.4) to prioritize ensuring that the luggage can reach the destination quickly and on time, and to avoid affecting the normal operation of the flight due to transportation delays.

[0226] At the same time, the weight of the energy consumption cost is appropriately reduced (such as reduced to 0.2), allowing an increase in energy consumption in exchange for time savings to a certain extent.

[0227] The weight of the congestion index can be increased to 0.3 to place more emphasis on avoiding congested areas and ensuring smooth transportation.

[0228] The priority weight remains unchanged at 0.2, continuing to ensure priority handling of luggage for important flights and passengers.

[0229] For example, during off-peak hours for flight takeoff and landing, the volume of baggage transported is relatively small.

[0230] At this time, the weight of the time cost can be appropriately reduced (for example, reduced to 0.3), and the requirements for delivery time can be relatively relaxed.

[0231] Accordingly, the weight of energy consumption cost is increased (for example, to 0.3), and more emphasis is placed on energy conservation and consumption reduction, thereby reducing operating costs.

[0232] The weight of the congestion index is adjusted to 0.15. Due to the small transportation volume and relatively less congestion, the requirements for avoiding congestion are correspondingly reduced.

[0233] The priority weight remains at 0.25, continuing to give appropriate priority to important flights and passengers' baggage.

[0234] This dynamic weighting mechanism prevents system fluctuations caused by sudden weight changes. In practice, weighting strategies can be customized based on characteristics such as airport size and flight peak distribution, creating a precise "one airport, one plan" configuration.

[0235] Furthermore, the method further comprises step S4:

[0236] Control the actuator module to transport the baggage to the security inspection area for image recognition by the security inspection machine;

[0237] Select the transport path based on the image recognition result of the security inspection machine:

[0238] If the image judgment result is normal, the actuator module is controlled to continue conveying along the original conveying path;

[0239] If the image judgment result is abnormal, the actuator module is controlled to enter the conveying path for baggage inspection.

[0240] Furthermore, the method further comprises step S5:

[0241] According to the flight information of the baggage, the moving module is controlled to arrive at the target sorting channel;

[0242] Adjust the electromagnetic field effect of the stator module to make the corresponding mover module produce a predetermined tilt angle;

[0243] After the luggage slides into the designated slideway, the unloaded mover module is controlled to return to the starting position.

[0244] In summary, the planar magnetic levitation-based baggage handling method proposed in this invention achieves automated and intelligent baggage handling from check-in to sorting through closed-loop control of the entire process: "information collection - standard determination - path planning - precise transportation - security inspection and diversion - directional sorting." Leveraging the contactless drive characteristics and modular layout advantages of the magnetic levitation system, it leverages this to achieve automated and intelligent baggage handling from check-in to sorting.

[0245] The baggage handling method based on planar magnetic levitation proposed in this invention not only ensures traceability of the entire process through the unique binding of the mover module to the baggage, but also improves the flexibility of exception handling by dynamically adjusting the path through security inspection results. It also simplifies the traditional mechanical structure through precise tilt sorting achieved by electromagnetic field regulation, significantly improves baggage handling efficiency, reduces equipment maintenance costs, and adapts to the scenario requirements of airports of different sizes, providing an efficient and feasible technical solution for the intelligent upgrade of airport baggage handling.

[0246] Figure 5 A first layout diagram of a baggage handling system according to an embodiment of the present invention is disclosed. Figure 6 A second layout diagram of a baggage handling system according to an embodiment of the present invention is disclosed. Specific implementations of a baggage handling method based on planar magnetic levitation will be described in detail below with reference to FIG. 5 and FIG. 6 .

[0247] like Figure 5 As shown, the first position 901 to the fifteenth position 915a of the first layout is a conveyor line plane that is fully paved with stator modules. The specific implementation process is as follows:

[0248] After the baggage handling system is started, the mover modules are evenly distributed at the first position 901 of the baggage conveying line;

[0249] The passenger places the luggage at the first position 901 of the luggage conveyor line. The control system uses the luggage information collected by the depth camera (baggage feature recognition device 30) to execute the determination process in step S1, that is, to determine whether the luggage meets the consignment regulations:

[0250] Specifically, the control system first determines whether the checked baggage is placed in a legal position and checks whether the baggage is overlength. If so, the system triggers a reminder mechanism to guide the passenger to move the baggage to the oversized transport channel.

[0251] At the same time, the control system controls the corresponding moving module to perform magnetic levitation weighing based on the luggage position to determine whether the luggage is overweight. If the weight exceeds 50kg (the threshold is adjustable), the passenger is reminded to move the luggage to the large-item transportation channel. If the weight exceeds 20kg (the threshold is adjustable), the overweight information is fed back to the check-in staff, prompting the passenger to pay the corresponding overweight fee.

[0252] For checked baggage that meets the weight and size requirements, the control system executes the preliminary preparations in step S2, i.e., controls the corresponding actuator module to transport the baggage to a location where the check-in staff can attach the baggage tag.

[0253] After the check-in staff affixes the tag, they send the baggage information to the baggage handling system. The system records the baggage's dimensions, weight, flight information, mover module ID, time, and other data, and uniquely binds it to the mover module. Combining this information with the baggage information, the mover module's movement path and baggage sorting logic are planned, generating the optimal transport route and initiating full baggage check-in tracking (the core step of step S2).

[0254] At the same time, the corresponding moving submodule is controlled to transport the luggage from the second position 902 to the third position 903 and stop there to wait for the image recognition result of the security inspection machine 93;

[0255] Based on the image recognition result of the security inspection machine, the baggage handling system performs the diversion control in step S4, controlling the moving submodule to transport the baggage to the fourth position 904 of the conveyor line:

[0256] For luggage that is normal according to the image analysis result, the control system controls the moving module to check in the luggage along the optimal path planned in step S3, passing through the fourth position 904, the tenth position 910, the eleventh position 911, the twelfth position 912, and the thirteenth position 913a of the conveyor line in sequence, and finally stops at the fourteenth position 914a or the fifteenth position 915a of the conveyor line, waiting for manual or automatic handling robots to transfer the luggage to the check-in vehicle;

[0257] For bags with abnormal image recognition results, the control system directs the moving submodule to enter the inspection path, passing through the fourth, fifth, and sixth positions 904, 905, and 906 of the conveyor line, entering the bag opening room 91, and placing the bag opening table 92, awaiting inspection at the sixth position 906 of the conveyor line. After inspection, staff will place the bag at the seventh position 907 of the conveyor line, passing through the eighth and ninth positions 908, 909, and awaiting security inspection results again. Baggage with normal image recognition results will continue along the route planned in step S3, passing through the tenth, eleventh, 911th, twelfth, and thirteenth positions 913a of the conveyor line, and stopping at the fourteenth or fifteenth positions 914a, 915a. Baggage with still abnormal image recognition results will be returned for re-inspection.

[0258] The moving module that has completed the baggage conveyance returns to the check-in area (near the first position 901 ) along both sides of the conveyor line, waiting to receive the next piece of baggage, thus forming a cyclic operation.

[0259] In the second layout of the automatic sorting mode shown in FIG6 , the conveyor line plane from the first position 901 to the sixteenth position 916b of the second layout is filled with stator modules. The core difference between this and the layout of FIG5 lies in the implementation method of the sorting process. The specific implementation process is as follows:

[0260] After completing the pre-processes such as check-in and security check (with Figure 5 After the execution logic of steps S1 to S4 is consistent, the system enters the automatic sorting stage of step S5:

[0261] The baggage handling system plans a dedicated sorting route for each piece of baggage based on the bound flight information. It controls the moving module to sequentially move the checked baggage through the corresponding positions on the conveyor line until it reaches the preset position of the target sorting channel, which is the fifteenth position 915b in the second layout.

[0262] Subsequently, the control system adjusts the electromagnetic field parameters of the stator module to cause the corresponding mover module to produce a predetermined tilt angle, using gravity to smoothly slide the luggage into the designated slide 94 that matches the flight information. After the luggage is sorted, the empty mover module returns to the starting area (such as near the first position 901) along the preset return path to wait for the next piece of luggage.

[0263] At the same time, in automatic sorting mode, the system continuously monitors the real-time baggage flow on the conveyor line and dynamically adjusts the motion parameters (base speed, acceleration, etc.) of the mover module through a flow monitoring algorithm: when an increase in the number of baggage is detected, the operating speed of the mover module is automatically increased to improve the system throughput efficiency; when the baggage flow decreases, the speed is appropriately reduced to optimize energy consumption, ensuring the efficiency and economy of the entire conveying process.

[0264] The planar magnetic levitation-based baggage handling system and method provided by the present invention have the following beneficial effects:

[0265] 1) Significantly improve sorting efficiency and reliability: Through contactless magnetic levitation drive and intelligent path planning algorithms, high-speed, high-precision sorting operations are achieved, while improving processing capacity and completely eliminating failures caused by mechanical wear;

[0266] 2) Achieve accurate tracking throughout the entire process: Using coding recognition and magnetic field positioning technology, we build a full-process baggage tracking system, significantly improving tracking accuracy and reducing baggage loss rates;

[0267] 3) Enhanced scenario adaptability: A modular design enables real-time reconstruction of transportation routes to meet the intelligent operation requirements of modern airports;

[0268] 4) Improved intelligence: Integrated deep vision detection and suspended weighing functions can automatically identify and process various types of luggage, ensuring stable transportation of various types of luggage.
