Description

Technical Field

[0001] This invention relates to the field of airport baggage handling technology, and more specifically, to a baggage handling system and method based on planar magnetic levitation. Background Technology

[0002] Airport baggage handling systems are an indispensable core facility in air transport, responsible for the automated processing of passenger baggage from check-in to loading. The system mainly consists of check-in, security screening, conveying, sorting, storage, transfer, and loading stages. Through the coordinated operation of mechanical conveying equipment and information management systems, it ensures that baggage is delivered to its destination efficiently and accurately. Its performance directly impacts flight punctuality, passenger satisfaction, and airport operational efficiency. With the continuous growth of air passenger traffic, traditional baggage handling systems have gradually shown limitations in terms of speed, reliability, and flexibility.

[0003] Currently, airport baggage handling systems primarily rely on mechanical conveying equipment and sensor networks. In the conveying stage, belt conveyors and roller conveyors are the mainstream technologies, using motors to drive baggage transport. In the sorting stage, cross-belt sorters and flip-board sorting systems classify baggage based on flight information. While these systems meet basic requirements, they suffer from numerous problems in actual operation: long-term operation of mechanical components leads to severe wear and tear, resulting in unstable conveying and noise pollution; sorting speed is limited, and high-speed operation can easily lead to baggage slippage or sorting errors, making accurate baggage tracking difficult; the system relies on numerous sensors working together, increasing wiring complexity, failure rates, and maintenance costs. Furthermore, fixed conveying paths are difficult to adapt to dynamic adjustments, and energy efficiency needs improvement.

[0004] Existing magnetic levitation technology has begun to be applied in the field of planar transport systems. Although these magnetic levitation planar transport systems have solved the problems of complex structure and high friction loss of traditional linear motor systems, they are mainly designed for general logistics scenarios and lack specific optimization for airport baggage handling. They cannot meet the requirements of modern airports for high efficiency, high reliability and intelligence in baggage handling systems.

[0005] To address these issues, there is an urgent need to develop a new baggage handling solution based on magnetic levitation technology. Summary of the Invention

[0102] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 for illustrative purposes only and are not intended to limit the invention.

[0103] To address the problems of severe mechanical wear, low sorting efficiency, poor path flexibility, and insufficient functional integration in existing airport baggage handling systems, this invention proposes a baggage handling system and corresponding processing method based on planar magnetic levitation technology, in order to achieve high efficiency, intelligence, and high reliability in baggage transportation and sorting.

[0104] Figure 1 A schematic diagram of a baggage handling system based on planar magnetic levitation according to an embodiment of the present invention is disclosed, such as... Figure 1 As shown, the baggage handling system based on planar magnetic levitation proposed in this invention includes several moving sub-modules 10, several stator modules 20, a baggage feature recognition device 30, and a control system 40.

[0105] The stator modules 20 are used to build and lay the luggage transport plane and generate a controllable electromagnetic field.

[0106] The plurality of moving sub-modules 10 are used to carry luggage and interact with the electromagnetic field of the stator module 20 to achieve contactless levitation and driving.

[0107] The baggage feature recognition device 30 is used to acquire 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. It plans the motion path of the moving sub-module 10 and the baggage sorting logic by combining baggage information, and realizes motion control of the moving sub-module by dynamically adjusting the electromagnetic field parameters of the stator module 20.

[0109] This invention proposes a baggage handling system based on planar magnetic levitation. By combining magnetic levitation with intelligent control algorithms, a highly efficient transport system optimized for airport baggage handling is constructed, which significantly improves baggage handling efficiency, reduces operating costs, and provides reliable technical support for the intelligent upgrading of airports.

[0110] In this embodiment, the baggage feature recognition device 30 serves as the "smart eye" of the magnetic levitation baggage handling system. It achieves comprehensive collection of baggage information through high-precision three-dimensional perception technology, providing key data support for subsequent automated sorting and path planning.

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

[0112] The depth camera collects luggage information in real time and sends it to the control system 40. The luggage information includes the luggage's three-dimensional dimensions (length, width, height) and spatial placement information (center coordinates, edge coordinates, etc.).

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

[0114] Furthermore, as shown in Figures 5 and 6, a baggage feature recognition device 30 is installed above the baggage check-in area (i.e., the electronic scale conveyor) at the check-in counter, so that its field of vision completely covers the entire check-in area.

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

[0116] A depth camera collects 3D point cloud data of 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 location information, the control system 40 determines whether the luggage is placed in the preset check-in area, and at the same time determines whether the position of the luggage on the conveyor belt meets the subsequent sorting requirements.

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

[0119] The control system 40 compares the above size measurement results with the preset luggage size standard to determine whether the luggage exceeds the length limit.

[0120] When the length or width of the luggage exceeds the set threshold (e.g., 1000mm), the luggage is determined to be 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 submodule 10 is the core innovation of this system. Through the synergistic effect of code identification, real-time positioning and baggage information, the system achieves precise control of the entire baggage transportation process.

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

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

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

[0125] The coding and identification unit can use non-contact radio frequency identification technology or optical identification device to read the unique identification code of the moving submodule 10 in real time;

[0126] The position sensor can be a high-precision Hall sensor or a laser rangefinder, used to detect the real-time position information of the moving submodule 10 on the baggage transport plane.

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

[0128] Baggage information is entered by the baggage feature recognition device 30 during check-in. The control system 10 constructs a dynamic mapping relationship database of unique identification codes for moving sub-modules, real-time location information, and baggage information: during check-in, baggage information is bound to the moving sub-module codes; the coordinates of the moving sub-modules are updated in real time with the help of position sensors; based on the binding relationship, the baggage is tracked and managed throughout the entire process from check-in to sorting.

[0129] Furthermore, the control system 40 is equipped with a flow monitoring algorithm to achieve intelligent scheduling of the moving sub-module based on baggage flow, which is achieved through the following steps:

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

[0131] More specifically, the control system 40 monitors the number of baggage tags entered into the system per unit time in real time and uses it as a baggage flow parameter; the control system dynamically adjusts the motion parameters of the motion submodule according to the baggage flow parameter, the motion parameters including reference speed and acceleration, etc.

[0132] The control system achieves adaptive adjustment of motion parameters through a fuzzy logic controller. For example, the input baggage flow parameters include: area load factor (0-100%); remaining flight time (0-120 min); and the output motion parameters include: base speed (0.5-5 m / s); acceleration (0.1-2 m / 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 there is sufficient remaining flight time, the base speed and acceleration are reduced simultaneously.

[0135] The control system 40 dynamically adjusts the conveying capacity of the moving sub-modules by real-time monitoring of baggage flow, so that the conveying capacity of the moving sub-modules can adapt to changes in baggage flow. This optimizes system energy consumption while ensuring baggage handling efficiency, and realizes intelligent operation and management of the magnetic levitation baggage handling system.

[0136] The moving module 10 and the stator module 20 are the core moving components of this magnetic levitation baggage handling system, realizing contactless levitation and precise drive functions. The specific structural composition and working principle of these two key modules will be described in detail below.

[0137] The moving sub-module 10 provides support for the luggage. Several moving sub-modules 10 (the number is configured according to needs, such as 4, 6, etc.) are distributed at the bottom of the luggage or the corresponding support position to carry the luggage in coordination, so as to realize the stable carrying and transportation of the luggage in the conveying system.

[0138] Figure 2a A first schematic diagram illustrating the carrying method of the moving submodule and luggage according to an embodiment of the present invention is shown, as follows: Figure 2a As shown, the carrying method of the moving sub-module 10 and the luggage 70 is as follows: four moving sub-modules 10 are respectively arranged at the four corners (or corresponding support points) of the luggage 70. Through the joint action of the four moving sub-modules 10, the luggage 70 is carried from the bottom of the luggage from all sides, so as to lift and transport the luggage 70 in the transportation process.

[0139] Figure 2b A second schematic diagram illustrating the carrying method of the moving submodule and luggage according to an embodiment of the present invention is shown. Compared with Figure 2a, as shown... Figure 2b As shown, two additional moving sub-modules are arranged under the luggage. The six moving sub-modules work together to provide support for a single piece of luggage 70. Through the coordinated operation of multiple moving sub-modules, the luggage 70 is lifted from multiple points under it to adapt to the carrying and transportation needs of luggage of different sizes and weights in luggage transportation scenarios.

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

[0141] In this embodiment, the moving 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 located at the bottom of the mover and is used to achieve contactless levitation by interacting with the electromagnetic field of the stator module.

[0143] The conductive winding unit, composed of a triaxial orthogonal induction coil, is arranged above the permanent magnet unit and is used to sense the magnetic field changes of the stator unit and generate the Lorentz force to drive the movement of the sub-module.

[0144] The intelligent control unit is located at the center of the moving submodule and is used to process control signals and adjust the motion state of the moving submodule.

[0145] The protective shell encloses the aforementioned units and forms the 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 to generate a high-intensity and highly directional magnetic field, which interacts with the electromagnetic field of the stator module to enable the mover module to achieve contactless levitation and drive.

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

[0149] When the coil of the stator module 20 is energized and generates a magnetic field, the magnetic field interacts with the conductive winding to generate an electromotive force, thereby driving the moving module 10 to move in the plane, thus achieving precise control of the movement of the moving 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 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, calculate and generate motion state adjustment commands for the mover module 10, and the motion state of the mover module 10 includes speed, acceleration, etc.

[0153] The memory is used to store control programs, operating parameters, and status data.

[0154] The communication module is used to realize real-time data interaction with the stator module 20, receive control commands and provide feedback on the status information of the actuator module 10.

[0155] Figure 3 A schematic diagram illustrating the baggage transport plane and the baggage check-in process according to an embodiment of the present invention is shown, such as... Figure 3 As shown, the moving submodule 10 carries the baggage 70 and runs on the baggage transport plane 80.

[0156] Multiple stator modules are modularly assembled to form a luggage conveyor plane 80, which has flexible adaptability: it can support users to freely combine and expand according to the production line scenario, and can operate without complex supporting mechanisms, greatly simplifying the mechanical structure design of the production line; it can also be freely arranged into any shape as needed, and combined with the adaptability of multiple sizes and multiple load capacities, it can meet the needs of diverse application scenarios.

[0157] The specific structural composition and working principle of the stator module 20 will be introduced next.

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

[0159] The coil group is used to generate a controllable electromagnetic field to achieve levitation and driving of the moving submodule 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 components and is used to dynamically adjust the direction and magnitude of the current according to control commands to control the motion trajectory of the motion submodule 10.

[0162] The position sensor uses a non-contact detection method to acquire the position information of the moving submodule 10 in real time.

[0163] More specifically, the coil group adopts multilayer printed circuit board (PCB) coils or wound coils, which generate a uniform and adjustable electromagnetic field after being energized, and interact with the permanent magnet unit in the moving sub-module 10 to realize the levitation and driving of the moving sub-module 10.

[0164] The layout and dimensions of the coil assembly are precisely designed to ensure that the magnetic field distribution meets the requirements for levitation 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 to precisely control the high-frequency alternating current parameters (current magnitude and frequency) to adjust the magnetic field strength and rate of change to adapt to the different motion state requirements of the moving submodule.

[0166] More specifically, the motion control unit is used to generate a driving magnetic field to enable precise motion control of the moving submodule 10 within the luggage transport plane.

[0167] The motion control unit can generate a rotating and translating magnetic field within the baggage transport plane by changing the direction and magnitude of the current in the coil group, guiding the moving sub-module to move along a predetermined path and achieving speed and acceleration adjustment.

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

[0169] Adjacent stator modules 20 are connected through standardized interfaces, and the topology of the baggage conveying plane is reconstructed according to the needs of different sorting scenarios.

[0170] More specifically, the stator module 20 adopts a modular splicing structure design, with each module tightly connected through mechanical interfaces to form a complete baggage conveying plane. This design allows the system to flexibly adjust the shape and size of the conveying plane according to actual needs, facilitating expansion and layout optimization.

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

[0172] The mechanical interface is designed with precise positioning and fastening devices to ensure a tight fit between modules without gaps, thereby ensuring that the moving sub-module 10 can operate smoothly on the assembled baggage transport plane without being affected by the module splicing points.

[0173] Mechanical interfaces have a certain degree of flexibility, which can adapt to minor 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 equipped with a standardized power interface and a communication interface;

[0175] The power interface adopts a cascaded power supply design to realize the power connection between adjacent stator modules and the access of external power supply.

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

[0177] The power interface and communication interface are electrically connected between 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 safe power disconnection for the module in abnormal situations and protecting equipment and personnel. When multiple modules are connected, the power interface supports cascading power supply between modules, enabling power connection between adjacent modules via adapters to ensure power supply across the entire transmission plane.

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

[0181] During mechanical assembly, communication and power cables between stator modules 20 are connected via concealed channels, maintaining a clean and flat conveyor plane. This integrated design simplifies system wiring, facilitates installation and maintenance, and improves overall system performance.

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

[0183] Furthermore, the stator module 20 also 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 sensors are used to monitor the operating current and voltage parameters of the coil group in real time.

[0186] The control system analyzes the temperature, current, and voltage data to achieve real-time monitoring, early warning of anomalies, and adjustment control of the stator module's operating status.

[0187] Through real-time acquisition and intelligent analysis of multi-dimensional data such as temperature, current, and voltage, the intelligent monitoring unit constructs a health monitoring system for the stator module 20. This system not only provides early warning of potential faults (such as overheating and abnormal current) but also provides data support for the dynamic optimization of operating parameters of the control system, 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 moving sub-modules can be deeply integrated. In addition to carrying and transporting, they can also be weighed using the magnetic levitation characteristics. Since each moving sub-module can also be used as a high-precision scale, there is no need for electronic scales at all.

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

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

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

[0192] By establishing an electromagnetic force-mass conversion relationship, the electromagnetic force value is converted into a luggage weight value.

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

[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 accurately measuring the electromagnetic force required to maintain the levitation of each rotor.

[0195] The electromagnetic force calculation model and the electromagnetic force-mass conversion relationship are as follows:

[0196] ;

[0197] Where F is the levitation force (N), m is the load mass (kg), g is the gravitational acceleration (9.81m / s²), k is the electromagnetic coefficient (N·m² / A²), I is the coil current (A), and d is the levitation gap (m).

[0198] In this embodiment, by integrating electromagnetic force monitoring and mass conversion logic, the moving module can accurately obtain the weight of luggage without an additional electronic scale by leveraging the correlation between coil current, suspension gap and electromagnetic force while carrying luggage. This achieves integrated conveying and weighing functions, simplifies system hardware configuration, and improves the intelligence and efficiency of the luggage handling process.

[0199] To achieve accurate baggage sorting by flight, this embodiment utilizes the coordination of the control system 40, stator module 20, and actuator module 10 to construct a sorting mechanism based on electromagnetic field control.

[0200] In this embodiment, the control system 40 generates tilt control commands based on the baggage's flight information;

[0201] The stator module 20, in response to the tilt control command, adjusts the current parameters of the coil group at the corresponding position to establish an electromagnetic field effect;

[0202] The moving module 10 produces a controlled tilting action under the action of the electromagnetic field;

[0203] The tilting action is used to guide baggage to a designated sorting chute to complete the sorting operation according to flight information.

[0204] In this embodiment, by utilizing the electromagnetic control characteristics of the magnetic levitation system, baggage can be accurately guided into the corresponding flight sorting chute without the need for complex mechanical structures, thereby efficiently realizing automated sorting according to flight information and improving the intelligent sorting capability of the baggage handling system.

[0205] In this embodiment, the baggage handling system based on planar magnetic levitation further includes:

[0206] The power supply cable 62 is connected to the power interface of each stator module 20 and is used to provide working power to the stator module 20;

[0207] Communication cables 61 are connected to the communication interfaces of each stator module 20 and the control system 40, respectively, to realize data communication between stator modules 20.

[0208] In this embodiment, the baggage handling system based on planar magnetic levitation further includes:

[0209] Mounting bracket 50 provides a rigid support reference surface for the stator module array, ensuring the flatness and parallelism requirements between modules.

[0210] Mounting bracket 50 not only achieves stable installation and precise positioning of the stator module, but also provides the system with flexible expansion capabilities through its modular structure, providing a reliable physical support platform for the engineering application of the planar magnetic levitation baggage handling system.

[0211] In summary, the baggage handling system based on planar magnetic levitation proposed in this invention constructs a flexibly expandable baggage transport plane through a modular stator, and utilizes the electromagnetic interaction between the mover module and the stator module to achieve contactless levitation, driving, 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.

[0212] Using the above-mentioned baggage handling system based on planar magnetic levitation, this invention also proposes a baggage handling method based on planar magnetic levitation.

[0213] Figure 4 A step diagram of a baggage handling method based on planar magnetic levitation according to an embodiment of the present invention is disclosed, as follows: Figure 4 As shown, the present invention proposes a baggage handling method based on planar magnetic levitation, which includes the following steps:

[0214] Step S1: Obtain baggage information to determine whether the baggage meets the check-in requirements;

[0215] Step S2: Uniquely bind the baggage information that meets the specifications to the moving sub-module, and plan the movement path of the moving sub-module and the baggage sorting logic in combination with the baggage information to generate the optimal delivery path;

[0216] Step S3: Based on the optimal transport path, control the moving submodule to transport the luggage.

[0217] When determining the optimal transport route, intelligent planning is performed based on a multi-factor weighted decision model to calculate the comprehensive score of each candidate route and select the route with the highest comprehensive score as the optimal transport route.

[0218] The following judgment factors and their impact on baggage handling efficiency and system performance are mainly considered, and corresponding weights are set accordingly.

[0219] In this embodiment, the judgment factors include time cost (t), energy cost (E), congestion index (D), and priority weight (P):

[0220] Time cost primarily reflects the transportation time required for baggage to travel from its origin to its destination, which directly impacts baggage handling efficiency and flight punctuality. Shorter transportation times ensure baggage arrives at its designated location faster, reducing passenger waiting time and improving airport operational efficiency.

[0221] Energy costs involve energy consumption during baggage handling. Optimizing routes to reduce energy consumption can not only reduce operating costs but also help airports achieve their environmental goals of energy conservation and emission reduction.

[0222] The congestion index reflects the degree of congestion along the transport route. Avoiding congested areas can prevent delays and backlogs of luggage during transport, ensuring smooth and stable transport and improving system reliability.

[0223] Priority weights are primarily determined based on the urgency and importance of the flight. For example, higher priority weights are given to flights about to depart or to the baggage of important passengers to ensure that this baggage is transported and processed with priority.

[0224] Optionally, the weights for time cost (α=0.35), energy cost (β=0.25), congestion index (γ=0.2), and priority weight (δ=0.2) can be assigned.

[0225] Furthermore, in different baggage handling scenarios, the weight parameters of the multi-factor weighted decision-making model are dynamically adjusted according to the actual situation and needs:

[0226] For example, baggage handling volume increases significantly during peak flight arrival and departure times.

[0227] At this point, the weight of time cost should be appropriately increased (e.g., to 0.4) to prioritize ensuring that baggage can reach its destination quickly and on time, and to avoid affecting the normal operation of flights due to transportation delays.

[0228] At the same time, appropriately reducing the weight of energy consumption costs (such as reducing it to 0.2) allows for an increase in energy consumption to some extent in exchange for time savings.

[0229] The weight of the congestion index can be increased to 0.3 to place greater emphasis on avoiding congested areas and ensuring smooth transportation.

[0230] The priority weight remains unchanged at 0.2, continuing to ensure priority handling of baggage for important flights and passengers.

[0231] For example, during off-peak flight times, baggage handling volume is relatively low.

[0232] At this point, the weight of time cost can be appropriately reduced (e.g., reduced to 0.3), and the requirements for delivery time can be relaxed somewhat.

[0233] Accordingly, the weight of energy consumption costs is increased (e.g., to 0.3), with greater emphasis on energy conservation and consumption reduction to lower operating costs.

[0234] The weight of the congestion index has been adjusted to 0.15. Since the traffic volume is relatively small and congestion is relatively rare, the requirement to avoid congestion is reduced accordingly.

[0235] The priority weight remains at 0.25, continuing to give appropriate priority to important flights and passengers' baggage.

[0236] This dynamic weighting mechanism avoids system oscillations caused by sudden changes in weights. In practical applications, weighting strategies can be customized based on characteristics such as airport size and flight peak distribution to form a precise configuration of "one solution for each airport".

[0237] Furthermore, the method further includes step S4:

[0238] The control submodule transports the luggage to the security check area for image processing by the security scanner;

[0239] Based on the image analysis results from the security inspection machine, select the transport path:

[0240] If the image judgment result is normal, the control submodule continues to transport along the original transport path;

[0241] If the image analysis result is abnormal, the control submodule will switch to the baggage inspection transport path.

[0242] Furthermore, the method further includes step S5:

[0243] Based on the baggage's flight information, the control submodule moves to the target sorting channel;

[0244] Adjust the electromagnetic field of the stator module to cause the corresponding moving sub-module to tilt at a predetermined angle;

[0245] After the luggage slides into the designated slide, the unloaded moving submodule is controlled to return to the starting position.

[0246] In summary, the baggage handling method based on planar magnetic levitation proposed in this invention achieves automated and intelligent baggage handling from check-in to sorting through a closed-loop control of the entire process of "information collection - standardized judgment - route planning - precise transportation - security check and diversion - targeted sorting". Relying on the contactless driving characteristics and modular layout advantages of the magnetic levitation system, it realizes automated and intelligent baggage handling from check-in to sorting.

[0247] The baggage handling method based on planar magnetic levitation proposed in this invention not only ensures full-process traceability through the unique binding of the moving module to the baggage, and improves the flexibility of anomaly handling by dynamically adjusting the path through security inspection results, but also simplifies the traditional mechanical structure by using electromagnetic field control to achieve precise tilt sorting. This significantly improves baggage handling efficiency, reduces equipment maintenance costs, and adapts to the needs of airports of different sizes, providing an efficient and feasible technical solution for the intelligent upgrade of airport baggage handling.

[0248] 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. The specific implementation of the baggage handling method based on planar magnetic levitation will be described in detail below with reference to FIG5 and FIG6.

[0249] like Figure 5 As shown, positions 901 to 915a of the first layout form a conveyor line plane fully covered with stator modules. The specific implementation process is as follows:

[0250] After the baggage handling system is started, the moving sub-modules are evenly distributed at the first position 901 on the baggage conveyor line;

[0251] The passenger places their luggage at the first position 901 on the luggage conveyor line. The control system uses the luggage information collected by the depth camera (luggage feature recognition device 30) to execute the judgment process in step S1, that is, to determine whether the luggage meets the check-in specifications:

[0252] Specifically, the control system first determines whether the placement of the checked baggage is compliant and checks whether the baggage is oversized; if it is oversized, the system triggers an alert mechanism to guide the passenger to move the baggage to the oversized baggage transport channel.

[0253] Meanwhile, the control system controls the corresponding moving submodule to perform magnetic levitation weighing based on the baggage's location to determine if the baggage is overweight: if the weight exceeds 50kg (threshold adjustable), the passenger is reminded to move to the overweight transport channel; if the weight exceeds 20kg (threshold adjustable), the overweight information is fed back to the check-in staff, prompting the passenger to pay the corresponding overweight fee.

[0254] For checked baggage that meets the weight and size requirements, the control system performs the preliminary preparation step S2, which involves controlling the corresponding moving submodule to transport the baggage to a location where check-in staff can affix baggage tags.

[0255] After check-in staff affix the tags, they send the baggage information to the baggage handling system. The system records data such as baggage size, weight, flight information, moving module ID, and time, and uniquely binds it to the moving module. Based on the baggage information, the system plans the movement path of the moving module and the baggage sorting logic, generates the optimal transport path, and initiates full-process tracking of baggage check-in (the core step of step S2).

[0256] 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, waiting for the image judgment result of the security inspection machine 93;

[0257] Based on the image analysis results from the security scanner, the baggage handling system executes step S4, which involves diverting the baggage to the fourth position 904 on the conveyor line.

[0258] For baggage whose image analysis result is normal: the control system controls the motion module to transport the baggage along the optimal path planned in step S3, passing through the fourth position 904, tenth position 910, eleventh position 911, twelfth position 912, and thirteenth position 913a of the conveyor line in sequence, and finally stopping at the fourteenth position 914a or fifteenth position 915a of the conveyor line, waiting for manual or automated handling robots to transfer it to the transport vehicle;

[0259] For baggage with an abnormal security check result: The control system controls the motion submodule to enter the security check path, passing through the fourth position 904, fifth position 905, and sixth position 906 of the conveyor line in sequence, entering the baggage opening room 91 and placing it on the baggage opening table 92, waiting for security check at the sixth position 906 of the conveyor line; after security check, the staff places the baggage at the seventh position 907 of the conveyor line, passing through the eighth position 908 and ninth position 909 in sequence, waiting for security check results again; baggage with a normal security check result continues to be transported along the path planned in step S3, passing through the tenth position 910, eleventh position 911, twelfth position 912, and thirteenth position 913a of the conveyor line in sequence, and stopping at the fourteenth position 914a or fifteenth position 915a; baggage with an abnormal security check result is returned for re-inspection;

[0260] After completing the baggage transfer, the moving module returns to the check-in area (near position 901) along both sides of the conveyor line, waiting to receive the next piece of baggage, thus forming a cycle operation.

[0261] In the second layout of the automatic sorting mode shown in Figure 6, the first position 901 to the sixteenth position 916b of the second layout is a conveyor line plane filled with stator modules. The core difference between this layout and the layout in Figure 5 lies in the implementation method of the sorting process. The specific implementation process is as follows:

[0262] After completing the pre-check-in, security check and other preliminary processes (and) Figure 5 After the execution logic of steps S1 to S4 is consistent, the system enters the automatic sorting stage in step S5:

[0263] Based on the bound flight information, the baggage handling system plans a dedicated sorting path for each piece of baggage, controls the moving sub-module to carry the baggage through the corresponding position of the conveyor line in sequence, and accurately arrives at the preset position of the target sorting channel, namely the fifteenth position 915b of the second layout.

[0264] Subsequently, the control system adjusts the electromagnetic field parameters of the stator module to make the corresponding moving sub-module tilt at a predetermined angle, and uses gravity to smoothly slide the baggage into the designated slide 94 that matches the flight information; after the baggage is sorted, the empty moving sub-module returns to the starting area (such as near the first position 901) along the preset return path, waiting to receive the next piece of baggage.

[0265] Meanwhile, in automatic sorting mode, the system continuously monitors the real-time baggage flow on the conveyor line and dynamically adjusts the motion parameters (baseline speed, acceleration, etc.) of the moving sub-modules through a flow monitoring algorithm: when the number of baggage increases, the operating speed of the moving sub-modules 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.

[0266] The baggage handling system and method based on planar magnetic levitation provided by this invention have the following beneficial effects:

[0267] 1) Significantly improve sorting efficiency and reliability: Through contactless magnetic levitation drive and intelligent path planning algorithm, high-speed and high-precision sorting operations are achieved, which improves processing capacity and completely eliminates failures caused by mechanical wear.

[0268] 2) Achieve precise tracking throughout the entire process: By adopting coding recognition and magnetic field positioning technology, a baggage tracking system is built throughout the entire process, which greatly improves the tracking accuracy and reduces the baggage loss rate;

[0269] 3) Enhance scenario adaptability: Real-time reconstruction of transport paths is achieved through modular design to meet the intelligent operation needs of modern airports;

[0270] 4) Enhance intelligence: Integrating depth vision detection and floating weighing functions, it can automatically identify and process various types of luggage, ensuring stable transportation of all types of luggage.
