Description

Technical Field

[0001] The present invention belongs to the field of boarding gate actuation control, and in particular relates to a boarding gate control system and a control method based on a battery and a supercapacitor. Background Art

[0002] Currently, emergency opening of the boarding doors (which also serve as emergency doors) on medium- and large-sized civil airliners, both domestically and internationally, is achieved through an emergency actuator mounted on the door. This actuator typically uses high-pressure gas or a mixture of oil and gas as its energy source to release energy for emergency opening. During normal opening, it acts as a damper, limiting the speed of the door's movement to prevent accidental injury to crew and passengers and ensuring the integrity of the fuselage structure. During emergency opening, the emergency actuator serves as the power source, releasing energy from its own high-pressure gas tank, enabling the door to open automatically and quickly within a specified timeframe.

[0003] Prior art applications include EP02079650, which proposes an emergency actuation system that uses chemical substances in an actuator, generating a chemical reaction that pushes a piston rod to extend. This requires further chemical refilling after a single use. US14119901, which proposes a mechanical elastic compression device for emergency actuation, requires resetting after a single use. EP16788220, which proposes an aircraft emergency door opening system and control method, utilizes a mechanical structure and switching between different slideways to achieve both normal and emergency opening. FR2830564 and EP0741073 utilize a jack-like pneumatic or hydraulic actuator equipped with a fluid reservoir for emergency actuation. Existing solutions suffer from complex product designs, non-renewable energy sources, repeated inflation and potential leakage, and poor economic efficiency. Summary of the Invention

[0013] Optionally, the sensor assembly 15 includes an actuator monitoring sensor group and a boarding gate position monitoring sensor group;

[0014] The actuator monitoring sensor group is used to monitor the position status of the actuator and provide feedback to the boarding gate actuation control module 1. The boarding gate actuation control module 1 performs logical judgment based on the actuator position status information and controls the actuator to be on and off according to a pre-set logical sequence.

[0015] The gate position monitoring sensor group is used to monitor the gate position status and feed back to the gate actuation control module 1; the gate actuation control module 1 gives a gate status indication and abnormal status alarm based on the gate position status information.

[0026] Figure 1 A schematic diagram of a boarding gate control system based on supercapacitors. DETAILED DESCRIPTION

[0027] In this embodiment, combined Figure 1 As shown, a supercapacitor-based boarding gate control system is provided, including a boarding gate actuation control module 1, an onboard power supply 2, a battery pack 3, a charging module 4, a discharging module 5, a supercapacitor unit 6, a capacitance balancing unit 7, a gust lock actuator 8, a flight lock actuator 9, a pre-position actuator 10, a control panel 11, an inverter module 12, a latch actuator 13, an opening actuator 14, and a sensor assembly 15.

[0028] The onboard power supply 2 is connected to the boarding gate actuation control module 1 , and the boarding gate actuation control module 1 responds to input instructions from the control panel 11 when the onboard power supply 2 provides power.

[0029] The gust lock actuator 8, flight lock actuator 9, arming actuator 10, latching actuator 13, and opening actuator 14 are respectively mounted on the corresponding boarding door gust lock mechanism, flight lock mechanism, arming mechanism, latching mechanism, and parallel opening mechanism. The gust lock actuator 8, flight lock actuator 9, arming actuator 10, latching actuator 11, and opening actuator 14, driven by their own motors and power output mechanisms, lock / unlock the gust lock, lock / unlock the flight lock, arm / unarm the handle, latch / unlatch, and open / close the boarding door.

[0030] The boarding gate actuation control module 1 is connected to the gust lock actuator 8, flight lock actuator 9, pre-position actuator 10, latch actuator 11 and opening actuator 14 through the provided cables.

[0031] The gate actuation control module 1 controls the gust lock actuator 8, the flight lock actuator 9, the arming actuator 10, the latch actuator 11 and the opening actuator 14 to perform actuations in a prescribed logical sequence.

[0032] The sensor assembly 15 includes an actuator monitoring sensor group and a gate position monitoring sensor group. The actuator monitoring sensor group monitors the position status of the actuator and provides feedback to the gate actuation control module 1. The gate actuation control module 1 performs logical judgment based on the actuator position status information and controls the actuator to switch on and off according to a pre-set logical sequence. The gate position monitoring sensor group monitors the position status of the gate and provides feedback to the gate actuation control module 1. The gate actuation control module 1 provides a gate status indication and abnormal status warning based on the gate position status information.

[0033] The onboard power supply 2 provides power to the boarding gate actuation control module 1. At the same time, the boarding gate actuation control module 1 charges the battery pack 3 and the supercapacitor unit 6 through the charging module 4. When the charged power of the battery pack 3 and the supercapacitor unit 6 reaches a preset threshold, the boarding gate actuation control module 1 stops charging them.

[0034] The boarding gate actuation control module 1 is connected to the battery pack 3 via a provided cable. After the onboard power supply 2 is powered off, the battery pack 3 starts discharging through the discharge module 5 to provide power to the boarding gate actuation control module 1, thereby ensuring that the boarding gate actuation control module 1 and the system can continue to perform normal monitoring functions.

[0035] The states of the sensors in the sensor assembly 15 determine the logical sequence of the control actuations of the gust lock actuator 8 , the flight lock actuator 9 , the arming actuator 10 , the latch actuator 11 and the opening actuator 14 .

[0036] When the onboard power supply is normal, the boarding door actuation control module 1 responds to the normal opening input command of the control panel 11; the boarding door actuation control module 1 controls the flight lock actuator 9, the pre-position actuator 10, the latch actuator 13, the opening actuator 14 and the gust lock actuator 8 to actuate in sequence according to the actuator action status feedback from the actuator monitoring sensor group after comprehensive logical judgment; among them, after the previous actuator has actuated into place, the boarding door actuation control module 1 controls the next actuator to actuate.

[0037] When the onboard power supply is normal, the boarding gate actuation control module 1 responds to the normal closing input command of the control panel 11; the boarding gate actuation control module 1 controls the gust lock actuator 8, the opening actuator 14, the latch actuator 13, the pre-position actuator 10, and the flight lock actuator 9 to actuate in sequence according to the actuator action status feedback from the actuator monitoring sensor group after comprehensive logical judgment; among them, after the previous actuator has actuated into place, the boarding gate actuation control module 1 controls the next actuator to actuate.

[0038] When the onboard power fails, the boarding gate actuation control module 1 switches to the battery pack 3 for power supply, and the boarding gate actuation control module 1 supplies power to the control panel 11 and the sensor assembly 15 to meet the needs of the boarding gate actuation control module 1 for monitoring the boarding gate position status.

[0039] When the gate activation control module 1 responds to the emergency opening input command from the control panel 11, it controls the flight lock actuator 9, the arming actuator 13, and the latch actuator 14 to perform flight lock unlocking, disarming, and unlatching actions in accordance with a preset logical sequence and in conjunction with the signal from the sensor assembly 15. After receiving the unlatching signal from the sensor assembly 15, the gate activation control module 1 controls the discharge module 5 via a cable to rapidly discharge the supercapacitor unit 6, generating a large current to provide the current required for the emergency opening of the opening actuator 14. Simultaneously, the supercapacitor unit 6 is connected to the capacitance balancing unit 7 to balance the capacitance of the supercapacitor module 6, thereby ensuring the required time for emergency opening.

[0040] Furthermore, by adjusting the capacity of the battery pack 3, when the onboard power supply 2 loses power, the battery pack 3 can provide power to the boarding gate actuation control module 1 and each actuator through the discharge module 5, thereby ensuring that the boarding gate actuation control module 1 and the system can continue to operate normally. When the onboard power supply 2 fails and loses power, the boarding door actuation control module 1 responds to the emergency opening input command of the control panel 10 while the battery pack 3 provides power. The boarding door actuation control module 1 controls the flight lock actuator 9, the pre-position actuator 13, and the latch actuator 14 to perform flight lock unlocking, releasing the pre-position, and unlatching actions in accordance with a preset logical sequence and in combination with the signal of the sensor assembly 15. After the boarding door actuation control module 1 receives the unlock latch in place signal from the sensor assembly 15, the boarding door actuation control module 1 controls the discharge module 5 through a cable to cause the supercapacitor unit 6 to discharge rapidly and generate a large current instantaneously. The boarding door actuation control module 1 transmits the large current to the opening actuator 14 to cause it to move rapidly, thereby realizing the emergency opening of the boarding door.

[0041] In addition, in actual application, the number of gate control systems is arranged according to the number of gates on the actual aircraft. Under normal circumstances, the gate control system obtains power through the onboard power supply 2. After the system is powered on, the gate actuation control module 1 collects the status of the sensors in the sensor assembly 15 in real time. At the same time, the gate actuation control module 1 receives the normal opening command input by the control panel 11 in real time; after receiving the command, the gate actuation control module 1 controls the gust lock actuator 8, the flight lock actuator 9, the pre-position actuator 10, the latch actuator 13 and the opening actuator 14 in accordance with the preset logical sequence to perform actuation, so as to realize the gust lock locking / unlocking, flight lock locking / unlocking, latching / unlatching and opening / closing of the gate.

[0042] In this embodiment, electromagnetic actuators are used for the gust lock actuator 8 and the flight lock actuator 9; rotary or linear actuators are used for the pre-position actuator 10, the latch actuator 13, and the release actuator 14. The latch actuator 13 and the release actuator 14 can be powered by either AC or DC.
