Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of airport transportation equipment, and in particular to an anti-misalignment system for a shuttle bus of a ground handling company. Background Art
[0002] With the rapid growth of international air transport, the efficiency and safety of airport passenger transfers are becoming increasingly critical operational management issues. This is especially true with the mixed operation of international and domestic flights, with the complex passenger profiles and strict boarding and alighting zones, placing higher demands on shuttle bus routes, docking accuracy, and boarding and alighting control. Existing airport shuttle buses often rely on manual instructions or broadcasts to guide passengers aboard. They lack dedicated identification mechanisms and automated error-proofing processes for international passengers, making it easy for passengers to be mistakenly transferred to the wrong arrival area, leading to border control disruptions, luggage delays, and even safety incidents.
[0003] Some improvement proposals attempt to assist drivers with their decisions by providing voice prompts or route labels. However, since these solutions rely on human recognition and operation, they lack an automated judgment mechanism. Consequently, there are still issues with "misplacement" caused by misjudgment, delayed information transmission, or incorrect button operation. Furthermore, existing systems often rely on static switching logic and lack a closed-loop judgment process based on real-time state perception. This is particularly true if an emergency occurs during vehicle operation, such as an emergency stop, system anomaly, voltage fluctuation, or a passenger alarm. Consequently, the system often cannot respond promptly, lacking a reliable emergency response path.
[0004] Furthermore, traditional door control strategies rely primarily on manual operation, failing to automatically determine whether the vehicle has accurately arrived at the target docking area and manage permissions. They also fail to effectively prevent accidental alighting caused by opening doors in non-target areas, posing significant safety risks. Therefore, an intelligent control system that integrates passenger status confirmation, door locking, precise docking identification, and emergency response is urgently needed to improve the safety, accuracy, and autonomy of airport shuttle buses in multi-passenger scenarios. Summary of the Invention
[0005] In view of the shortcomings of the prior art, the embodiment of the present invention aims to provide a ground handling company shuttle bus anti-misalignment system to solve the problems in the above-mentioned background technology.
[0006] To achieve the above object, the present invention provides the following technical solutions:
[0007] A ground handling company shuttle bus anti-misalignment system, including:
[0008] An information acquisition module is used to acquire passenger information, including whether the passenger is an international passenger, the number of international passengers, and the destination of the international passengers;
[0009] A control button module is configured to obtain arrival button information, which includes a first trigger button and a second trigger button. The arrival button information confirms the arrival of all international passengers. A door closing signal is sent based on the arrival button information, and the door closing signal is used to close the vehicle doors. The door opening button is controlled based on the arrival button information, and the control mode is to disable all door opening buttons.
[0010] The distance sensor module activates the distance sensor based on the arrival button information. The distance sensor is used to determine the distance between the vehicle and the international arrival gate and obtain distance sensor information in real time. The distance sensor information is the real-time distance between the vehicle and the international arrival gate. When the distance sensor information is equal to 0, a door opening signal is sent based on the distance sensor information. The door opening signal is used to open the vehicle door, and the vehicle operation panel is unlocked through the door opening signal.
[0011] The emergency module obtains the real-time status of the vehicle, determines whether the vehicle has an emergency according to the implementation situation, and sends a control signal to the unlock switch according to the emergency information acquisition and processing method. The unlock switch is used to forcibly open the door.
[0012] As a further solution of the present invention, the control button module includes:
[0013] The first trigger button and the second trigger button are electrically connected in parallel. Pressing either button is deemed to confirm that all international passengers have boarded the train.
[0014] After receiving the button press signal, the edge detection logic module identifies the trigger event, generates a "passenger boarding completed" status mark, and locks the state to prevent accidental touches or repeated operations;
[0015] Obtain feedback signals on the closing status of each door. If any door fails to close completely, the next control process is temporarily suspended and a reminder signal may be sent to the driver's console. The reminder signal may include a visual or sound reminder.
[0016] As a further solution of the present invention, the distance sensor module includes:
[0017] The distance sensor can be an infrared ranging, ultrasonic positioning, RFID identification module or geomagnetic / magnetic stripe sensor module. The distance sensor information is in millimeters or centimeters and is periodically updated at a fixed sampling frequency.
[0018] A predefined threshold distance value is set as the judgment standard. If the sensing value continuously meets this condition for a set duration, it is determined that the vehicle has accurately aligned with the international arrival gate and a signal to allow the door to open is sent to the door control module.
[0019] As a further solution of the present invention, the threshold distance value is less than 0.5m.
[0020] As a further solution of the present invention, the set duration is ≥ 2 seconds.
[0021] As a further solution of the present invention, the emergency module includes:
[0022] Real-time vehicle conditions include vehicle speed, acceleration, emergency stop status, system voltage anomalies, passenger-triggered emergency alarm signals, and driver operation records;
[0023] A plurality of determination conditions are set, and the determination adjustment is used to determine whether it is an emergency situation, and the emergency situation includes attempting to open the door when the vehicle is not parked, the emergency stop device is triggered, and abnormal driver operation.
[0024] As a further solution of the present invention, the first trigger button is set on the main driver's seat, and the second trigger button is set on the co-pilot's seat.
[0025] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:
[0026] The first and second trigger buttons, located on the driver and co-pilot seats, are electrically connected in parallel. Pressing either button confirms international passenger boarding and triggers subsequent control processes, offering flexible operation and strong safety redundancy. Combined with edge detection and a state lock mechanism, this effectively prevents control confusion caused by accidental touches or repeated inputs, improving system stability.
[0027] Secondly, after completing the passenger confirmation, the system automatically issues a door closing command and collects real-time feedback on the closing status of each door. If any door is found not closed, the process will be terminated and a clear prompt will be given to the driver through visual or sound means to ensure subsequent safe and reliable operation.
[0028] Next, the system activates the distance sensor based on the trigger signal and continuously collects the real-time distance between the vehicle and the target international arrival gate using infrared ranging, ultrasonic waves, RFID, or geomagnetic recognition. By setting a dual judgment mechanism based on threshold distance and duration, the system ensures that the door opening signal is issued only after the vehicle has accurately stopped at the designated location. This also releases the door operation permission lock, effectively preventing passengers from getting off the vehicle in the wrong place due to accidental parking or misaligned departure.
[0029] Finally, during operation, the system continuously captures multiple real-time data types, including vehicle speed, acceleration, power status, driver behavior, and passenger alerts. It then sets multiple emergency status criteria, such as door opening while the vehicle is not parked, emergency stop button activation, and driver loss of control. Once the system identifies an emergency, it bypasses the main control process and sends a forced door opening command to the unlocking switch via a high-priority channel, rapidly completing evacuation operations and ensuring passenger safety.

[0036] 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 present invention and are not intended to limit the present invention.
[0037] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0038] In one embodiment, a ground handling company shuttle bus anti-misalignment system, see Figures 1 to 5 , including the system includes:
[0039] An information acquisition module is used to acquire passenger information, including whether the passenger is an international passenger, the number of international passengers, and the destination of the international passengers;
[0040] A control button module is configured to obtain arrival button information, which includes a first trigger button and a second trigger button. The arrival button information confirms the arrival of all international passengers. A door closing signal is sent based on the arrival button information, and the door closing signal is used to close the vehicle doors. The door opening button is controlled based on the arrival button information, and the control mode is to disable all door opening buttons.
[0041] The distance sensor module activates the distance sensor based on the arrival button information. The distance sensor is used to determine the distance between the vehicle and the international arrival gate and obtain distance sensor information in real time. The distance sensor information is the real-time distance between the vehicle and the international arrival gate. When the distance sensor information is equal to 0, a door opening signal is sent based on the distance sensor information. The door opening signal is used to open the vehicle door, and the vehicle operation panel is unlocked through the door opening signal.
[0042] The emergency module obtains the real-time status of the vehicle, determines whether the vehicle has an emergency according to the implementation situation, and sends a control signal to the unlock switch according to the emergency information acquisition and processing method. The unlock switch is used to forcibly open the door.
[0043] For further information, see Figures 1 to 5 , the control button module includes:
[0044] The first trigger button and the second trigger button are electrically connected in parallel. Pressing either button is deemed to confirm that all international passengers have boarded the train.
[0045] After receiving the button press signal, the edge detection logic module identifies the trigger event, generates a "passenger boarding completed" status mark, and locks the state to prevent accidental touches or repeated operations;
[0046] Obtain feedback signals on the closing status of each door. If any door fails to close completely, the next control process is temporarily suspended and a reminder signal may be sent to the driver's console. The reminder signal may include a visual or sound reminder.
[0047] For further information, see Figures 1 to 5 , the distance sensor module includes:
[0048] The distance sensor can be an infrared ranging, ultrasonic positioning, RFID identification module or geomagnetic / magnetic stripe sensor module. The distance sensor information is in millimeters or centimeters and is periodically updated at a fixed sampling frequency.
[0049] A predefined threshold distance value is set as the judgment standard. If the sensing value continuously meets this condition for a set duration, it is determined that the vehicle has accurately aligned with the international arrival gate and a signal to allow the door to open is sent to the door control module.
[0050] For further information, see Figures 1 to 5 , the threshold distance value is less than 0.5m.
[0051] For further information, see Figures 1 to 5 , the set duration is ≥ 2 seconds.
[0052] For further information, see Figures 1 to 5 , the emergency module includes:
[0053] Real-time vehicle conditions include vehicle speed, acceleration, emergency stop status, system voltage anomalies, passenger-triggered emergency alarm signals, and driver operation records;
[0054] A plurality of determination conditions are set, and the determination adjustment is used to determine whether it is an emergency situation, and the emergency situation includes attempting to open the door when the vehicle is not parked, the emergency stop device is triggered, and abnormal driver operation.
[0055] For further information, see Figures 1 to 5 The first trigger button is set on the main driver's seat, and the second trigger button is set on the co-pilot's seat.
[0056] In this embodiment, the interactive input of the first and second trigger buttons can effectively confirm whether all international passengers have boarded the train, thereby ensuring that the train does not depart prematurely or enter the non-target arrival area before all passengers have arrived. This step can be further refined from the perspectives of button structure, trigger logic, signal recognition method, state locking, subsequent command execution chain, and example scenarios.
[0057] Two sets of physical buttons are provided: the first trigger button and the second trigger button. The first trigger button is fixed in the main driving console area for easy operation by the driver; the second trigger button is located in the co-pilot or crew operating position for onboard ground staff. The two sets of buttons are electrically connected in parallel, so that pressing either button can signal to the system that "all international passengers have arrived."
[0058] To improve signal recognition accuracy and response robustness, the system employs edge detection and debounce processing for button signals. Specifically, when the system receives a voltage change from any button (e.g., from a low level to a high level), the edge detection module triggers a one-time signal capture mechanism. Signal stability is then confirmed within a set time window (e.g., 100ms) to prevent misidentification caused by accidental touches or electrical interference.
[0059] Once a valid signal is confirmed, the system will automatically enter the "international passenger boarding completed" state, generate a unique status flag and write it into the central controller memory, while locking the state. Subsequent presses of the button will no longer trigger any state changes, ensuring state consistency.
[0060] After the system receives the signal from the first trigger button or the second trigger button being pressed, it confirms that all international passengers have boarded the bus. The system will enter the "International Passenger Mode" and, after all the doors are closed and the door opening button becomes ineffective, will perform the next key action: activating the distance sensor.
[0061] The distance sensor is originally in standby or dormant mode to reduce energy consumption and avoid meaningless data collection. When the system enters the international passenger mode, the power supply channel of the distance sensor is turned on and its data output interface is activated to continuously collect the current position of the vehicle. The distance sensor can be an infrared ranging, ultrasonic positioning, RFID recognition module or geomagnetic / magnetic stripe sensor module. The distance sensor information is in millimeters or centimeters and is periodically updated at a fixed sampling frequency.
[0062] Distance sensor information represents the real-time distance data between the vehicle and the international arrival gate, typically in millimeters (mm) or centimeters (cm). The system continuously reads this value at a fixed sampling frequency (for example, 5 times per second) and generates a structured location information data packet.
[0063] To ensure positioning accuracy, the system not only determines whether the result of a single sampling satisfies the distance of "0", but also adopts a continuous sampling average judgment mechanism.
[0064] The specific logic is as follows: set the threshold distance value D≤50cm; set the continuous sampling window time to ≥2 seconds; if the system collects data more than 5 times within 2 seconds, and all consecutive data meet D≤50cm, it is determined that the vehicle has accurately stopped at the target international arrival gate;
[0065] Once the system determines that the position meets the door opening conditions, it will send a door opening control signal, which will be sent to the door control module as a command to release the electric lock of the target door (usually the left / right front, middle and rear doors) so that it can be opened.
[0066] At the same time, the system automatically reactivates the door opening button permission on the operation panel that was previously invalidated due to safety lock.
[0067] During the operation of the vehicle in "International Passenger Mode", the real-time status of the vehicle is continuously obtained to monitor whether there are any abnormal conditions or emergencies. The real-time status of the vehicle includes the following data sources, which are collected through the distributed sensor network or vehicle bus system and aggregated to the main controller for judgment:
[0068] Multiple types of operational data are acquired through the vehicle's onboard sensor network or bus interface. These data reflect the vehicle's physical state and operational behavior during operation in real time, including vehicle speed, acceleration, emergency stop status, voltage status, emergency alarm signals, and driver operation records. Multiple emergency event determination conditions are set to identify whether an abnormal state has been entered. Once any of these conditions are met, it is considered an "emergency," interrupting the original process and executing emergency measures. Determination conditions include attempts to open the door while not parked, emergency stop device triggered, abnormal driver operation, abnormal voltage, passenger alarm triggering, and excessive acceleration or deceleration. Once the system identifies any emergency, it immediately enters a high-priority processing channel, including interrupting the current operation process and sending a forced unlock command to the door control module.
[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
