Description

Technical Field

[0001] This invention belongs to the field of intelligent transportation technology, and in particular relates to a teaching platform for intelligent airport surface traffic information and control. Background Technology

[0002] As the scale of civil airport operations gradually expands, the increasing complexity of airport surface traffic presents growing pressures on safety and efficiency, leading to developmental bottlenecks such as frequent surface safety incidents and low traffic efficiency. However, current issues include low levels of air-to-ground connectivity and information sharing at airport surfaces, weak monitoring and intelligent sensing capabilities of the surface operating environment, low levels of intelligence and automation in surface operations, and insufficient human-machine safety collaboration within the transportation system. These problems result in significant pressure on airport surface safety operations, low surface traffic capacity and reliability, and difficulty in addressing systemic surface control issues in complex airport traffic environments. In recent years, the level of automation and intelligence in the aviation transportation sector has been continuously improving. Surface intelligent control technology is closely related to the digitalization of transportation infrastructure and the intelligentization of transportation vehicles. To better prepare students for work in civil aviation flight operation command, operation support, and infrastructure maintenance, it is essential to cultivate their basic knowledge of traffic information processing and traffic equipment / facilities control.

[0003] Furthermore, the current teaching of airport operations control courses is closely integrated with practical engineering applications. Teaching experiments should not only solidify fundamental theoretical knowledge but also cultivate students' comprehensive engineering application abilities. However, this specialization currently lacks usable teaching experimental platforms. Students are unable to design their own inquiry-based experiments, failing to demonstrate their comprehensive practical abilities in "conception, design, and operation." Students cannot fully utilize their initiative through independent experimental practice. The key to these problems lies in the lack of experimental practice teaching content design and low-cost methods for building experimental teaching platforms that cultivate students' comprehensive engineering practice and innovation abilities.

[0041] Example 1

[0042] like Figure 1 As shown, this embodiment provides a smart airport surface traffic information and control teaching platform, including: a traffic platform and a teaching platform;

[0048] The teaching platform is used to autonomously plan different travel routes for the aircraft models, set up conflicts between aircraft models and between aircraft models and car models based on different travel routes, and resolve the conflicts based on the traffic platform, thereby optimizing the traffic platform.

[0049] The feasible control system includes a first control module, a second control module, and a third control module; the first control module is used to guide and control the movement and balance of the aircraft model and the car model; the second control module is used to control the on / off state of the lighting system to achieve different lighting effects; the third control module is used to receive instructions from external devices and adjust the movement state of the aircraft model and the car model based on the instructions; wherein, the external devices include at least a remote controller and a computer.

[0050] The feasible configuration includes a power supply module, a step-down module, a drive module, a tracking module, and a display module connected in sequence for both the aircraft model and the car model. The power supply module provides power to the aircraft model or car model. The step-down module reduces the high voltage provided by the power supply module to the corresponding voltage level of each module. The drive module controls the movement of the aircraft model or car model by adjusting the speed and direction of the motor.

The display module displays the status information of the aircraft model or car model through a display device.

[0051] The vehicle model can also include an auxiliary power module, which is used to provide a stable voltage for the vehicle model.

[0052] The feasible lighting system includes several lighting zones connected in parallel; the lighting system adopts segmented connection.

[0053] The feasible lighting system includes a first guidance module and a second guidance module; the first guidance module is used to guide the aircraft model forward based on the planned route between segments; the second guidance module is used to guide the car model forward along a route that does not conflict with the aircraft model by changing the direction of the light flow.

[0054] The feasible communication system includes a first communication module and a second communication module; the first communication module is used to realize data transmission between the control system, the traffic system and the lighting system; the second communication module is used to realize data transmission between the teaching platform and external devices.

[0055] The feasible teaching platform includes a conflict setting module and a conflict resolution module.

The conflict resolution module is used to resolve conflicts by adjusting the lights based on the traffic platform, thereby optimizing the travel routes of the aircraft models and car models.

[0056] The intelligent airport lighting control teaching platform proposed in this embodiment is derived from the real traffic design of conflict hotspots in airports. Based on this actual path structure, various vehicle road segments such as lanesides, aprons, terminals, and taxiways are added. Simultaneously, these systems can all be linked with airport lighting, controlling aircraft direction and planning vehicle routes to achieve coordinated operation between various road segments, aircraft, and vehicles. This optimizes airport conflict resolution. This experimental teaching platform is based on the theory of Advanced Airport Surface Activity Guidance and Control System (A-SMGCS). A-SMGCS effectively avoids conflicts between surface activity targets and significantly enhances airport security capabilities by monitoring, guiding, and controlling airport surface activities.

[0057] This embodiment addresses the trend of advanced surface activity guidance technology by designing experimental teaching scenarios such as surface aircraft taxiing paths, surface lighting control, automatic vehicle driving, and communication between surface activity objects and lights. Based on the existing A-SMGCS system framework, a construction scheme for an airport surface intelligent management experimental teaching platform is designed by constructing an airport runway simulation environment and modifying and simplifying the network structure. This scheme can meet the main functions required for experimental teaching while adhering to the principle of system minimization to save costs.

[0058] Example 2

[0059] A teaching platform for intelligent airport surface traffic information and control involves the functional implementation of the airport's lighting control system and main traffic control system, as well as the communication relationship between the airport's lighting system and traffic system.

[0060] The lighting control system is a crucial system that ensures safe landing of aircraft at night or in low visibility conditions, and plays a vital guiding and mitigating role in road conflicts between aircraft or between aircraft and vehicles. This embodiment installs lights on the gliding paths of aircraft and vehicles on a teaching platform, based on the actual conditions of the airport. The lighting control module is embedded in the teaching platform, and a microcontroller is used as the controller to pre-control the lights, providing clear guidance to the aircraft and vehicles so they can move along the designated paths.

[0061] The lighting system employs segmented connections and parallel access between zones. In this system, "segmented connection" and "parallel access between zones" are two key concepts describing the system's connection method and structure. Segmented connection refers to the physical layout and control logic of the lighting system being divided into several independent parts, each called a "segment." At the control level, segmented connection may mean that the lighting system can be managed through different control units. Parallel access between zones means that the luminaires in each lighting zone (or "segment") are connected to the power supply in parallel. In terms of connection, this means that the luminaires in each zone share the same power supply, but the positive and negative terminals of each luminaire are directly connected to the power supply, rather than in series, allowing each zone to be controlled independently. This configuration allows for a high degree of flexibility and independence, as each lighting zone can be turned on or off individually. Parallel connection allows the lights in each zone to operate independently, so even if the lights in other zones malfunction, it will not affect the lighting in other zones. In this system, each "segment" or "zone" can be considered an independent lighting control unit. These units are connected to the power supply in parallel, sharing the same power line. This design allows the lighting system to maintain overall harmony while flexibly responding to the lighting needs of different areas, and also facilitates fault diagnosis and maintenance.

[0062] This design offers improved fault diagnosis and maintenance capabilities because if a lighting issue occurs in a particular area, the problem can be more easily located, affecting only that specific area and not the entire system. Furthermore, the segmented lighting system is easier to expand; adding new lighting areas simply requires adding new control points and connections to the corresponding segments. Overall, this lighting system design aims to provide flexibility, scalability, ease of maintenance, and fault isolation to meet the needs of diverse environments and application scenarios.

[0063] In this embodiment, the airflow between segments guides the aircraft along a pre-planned route. The other vehicle route is an optimized route that avoids conflict with the aircraft's fixed path by changing the direction of the light flow. Based on the routing function of the A-SMGCS system concept, the system assigns routes and changes destinations and routes for each aircraft or vehicle in complex airport traffic conditions. This is also reflected in the on / off state of the smart lights, where changes in light are transmitted to the aircraft and vehicle paths.

[0064] Construction of Airplane and Car Models: Airplane and car models are two different modes of transportation. In the model-making field, airplane and car models are usually controlled by remote control devices, possessing a certain degree of autonomy and intelligence. To achieve these functions, they typically include the following modules:

[0065] Power Supply Module: This module is responsible for providing a stable power supply to the entire model. It converts battery or other energy sources into voltages and currents suitable for the various parts of the model.

[0066] Voltage Regulator Module: A voltage regulator module is used to reduce the higher voltage supplied by the power supply module to the voltage level required by each module. This helps protect the electronic components in the model from damage caused by excessive voltage.

[0067] Driver Module: The driver module is responsible for controlling actuators such as motors and motors in the model. It receives instructions from the controller and then adjusts the speed and direction of the motors or motors to achieve the movement of the model.

[0068] Line Following Module: The line following module enables the model to automatically travel along a specific path. It typically includes sensors (such as infrared sensors or cameras) to detect the path, and a controller to process the sensor signals and adjust the instructions of the drive module.

[0069] Display Module: The display module provides users with the model's status information, such as speed and orientation. This can be achieved through LED displays, LCD displays, or other display devices.

[0070] The power supply module provides power to other modules, the step-down module ensures that each module receives the appropriate voltage, the drive module controls the motors and actuators according to the controller's instructions, the tracking module and the balance module adjust the drive module's instructions by processing sensor signals, and finally, the display module provides the user with the model's status information. These modules work together to enable the airplane and car models to achieve various functions and autonomous movement.

[0071] In the construction of the teaching platform model, the microcontroller serves as the core controller, responsible for coordinating and controlling the operation of various modules. The logical relationships between the microcontroller and modules such as the airplane, car model, and communication system are as follows:

[0072] Microcontrollers and Airplane / Car Models: The microcontroller controls the motors and other actuators of the airplane or car through a drive module, enabling the model's movement. Simultaneously, the microcontroller can receive signals from sensors (such as gyroscopes and accelerometers) to achieve autonomous control and balance of the model. In this process, the microcontroller acts as the "guide and control" mechanism for the airplane or car model.

[0073] Microcontroller and Communication System: The communication system is responsible for data transmission between the teaching platform and external devices (such as remote controls, computers, etc.). The microcontroller receives instructions from external devices through the communication module and then adjusts the motion state of the airplane and car models according to the instructions. In this process, the communication system plays an "auxiliary implementation" role, helping to achieve remote control and data transmission.

[0074] Microcontroller and Lighting System: The lighting system provides visual feedback to enhance the fun and practicality of the teaching platform. The microcontroller controls the on / off state of lighting modules (such as LEDs) to achieve different lighting effects. In this process, the lighting system also plays an "auxiliary" role, adding color and visual appeal to the teaching platform.

[0075] In summary, the microcontroller plays a core control role in the teaching platform model. It collaborates with modules such as the airplane and car models, the communication system, and the lighting system to jointly realize the various functions of the teaching platform. The communication system and the lighting system, as auxiliary modules, are responsible for remote control, data transmission, and visual feedback, respectively, providing a richer experience for the teaching platform.

[0076] In a specific implementation, the first component is the power supply module. In the buck converter and drive circuit, the initial input power is a 12V model aircraft battery. The 5V output from the drive module powers the microcontroller, while the 5V output from the buck converter serves as the input for the 5V-to-3.3V conversion module, and also powers the tracking and display modules. The 3.3V output from the buck converter powers the balancing module. Typically, to ensure stable operation of the intelligent car circuitry, an auxiliary power supply is used to provide a stable voltage; this is essentially a buck converter. High-performance buck regulators such as the LM2576-5 and LM1117-3.3 are generally chosen, as these high-performance regulators effectively ensure smooth 12V to 5V and 5V to 3.3V conversions. Next is the L298N motor driver. In the STM32-based intelligent car control system, the L298N is selected as the driver integrated circuit, primarily for driving the DC motor. The L298N requires a 12V input to power the motor and a 5V input to power the development board. The STM32 core board has four pins that connect to the module's logic signal input ports, and the output PWM wave is used to effectively control the duty cycle. In addition, the motor output port of the drive module connects to the DC motor requiring drive, thereby precisely controlling the wheel steering and rotation speed of the car model. A communication module is used to transmit information with the lighting system and other traffic entities. The control of the aircraft and car models uses light signals to indicate their direction of travel. In the example, when the car travels through intersections, the system uses lights for guidance. Specifically, this is achieved by using LEDs installed on the teaching platform, and controlling the on / off state of the LEDs to guide the aircraft and car.

[0077] like Figure 2 As shown, this embodiment also includes setting up a conflict in the early stage of the experiment by fixing the aircraft's route and confirming the aircraft's direction of travel. Without affecting the aircraft's direction of travel, the movement of the car is guided by controlling the on / off state of the LED lights installed on the teaching platform, thus planning a safer route and avoiding conflicts with the aircraft.

[0078] The teaching platform designs different routes for teaching experiments, highly replicating the functionalities of conflicts between aircraft and between aircraft and vehicles in airport conflict hotspots. This allows for intuitive understanding of the problems, identification of core causes, and optimization of aircraft and vehicle routes by adjusting lighting. The experimental platform provides the most realistic simulation in teaching, achieving the effect of making theory concrete through experimentation. Through repeated experiments, the process is reviewed, the causes of problems are identified, optimization methods are tried, and experimental experience is summarized. Before the next experiment, more reasonable experimental routes and methods are planned. This series of post-experiment reviews has a positive feedback effect on the initial conflict setup, helping us to conduct more realistic, reasonable, and effective experiments.

[0079] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
