[0002] Aircraft ground air conditioning units are common external equipment for aircraft. After the boarding bridge is connected to the aircraft, the ground air conditioning unit provides pre-treated fresh air to the aircraft parked at the airport through air supply hoses, which are connected to the aircraft through connectors.

[0003] Existing technologies lack interlocking control devices for aircraft ground air conditioning units and boarding bridges. The status between the aircraft ground air conditioning units and boarding bridges cannot be intelligently interlocked. When the connection joint is in the state of being connected to the aircraft, operators may make mistakes and retract the boarding bridge (disconnect from the aircraft), which may easily lead to safety accidents such as pulling and damaging the aircraft. Utility Model Content

[0004] The main purpose of this application is to provide an intelligent interlocking control device with a simple structure that can prevent operator error and greatly reduce safety accidents such as pulling damage to aircraft.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] According to one aspect of this application, an intelligent interlocking control device for an aircraft external device and a boarding bridge is provided, comprising a first sensor and a controller. The first sensor is used to detect the connection status of the connection joint between the aircraft and the aircraft external device and generate connection status parameters. The controller is used to receive the connection status parameters and, based on the received parameters, generate an execution command for interlocking control of the aircraft external device and the boarding bridge.

[0007] According to one embodiment of this application, the intelligent interlocking control device further includes a second sensor, which is used to detect the retraction status of the connecting joint and generate retraction status parameters; the controller receives the retraction status parameters and generates the execution command, which is used to perform interlocking control on the aircraft external equipment and the boarding bridge.

[0008] According to one embodiment of this application, the external device of the aircraft includes a ground air conditioning unit, and the controller also receives the status signal of the ground air conditioning unit and generates the execution command based on the received signal. The execution command is used for human-machine interaction.

[0009] According to one embodiment of this application, when the status signal of the ground air conditioning unit is running, if the first sensor detects that the connection joint changes from a connected state to a disconnected state, the execution command includes an alarm command for alerting the operator.

[0010] According to one embodiment of this application, when the status signal of the ground air conditioning unit is stopped, if the first sensor detects that the connection joint is connected, the execution command includes a prompting command to prompt the operator to disconnect the connection joint.

[0011] According to one embodiment of this application, the ground air conditioning unit is connected to the aircraft via a duct, the duct being used to deliver fresh air generated by the ground air conditioning unit into the aircraft.

[0012] According to one embodiment of this application, the ground air conditioning unit further includes a duct retractor, and the second sensor is disposed on the duct retractor.

[0013] According to one embodiment of this application, the first sensor includes a switching element and is disposed on the connector; and / or the second sensor includes a switching element.

[0014] According to one embodiment of this application, when the second sensor detects that the retracted state of the connecting joint is not retracted, the execution command includes a locking command for locking the boarding bridge, so that the boarding bridge is in the state of being connected to the aircraft.

[0015] According to one embodiment of this application, when the first sensor detects that the connector is in a connected state, the execution command includes a locking command for locking the boarding bridge, so that the boarding bridge is in a connected state to the aircraft.

[0016] As can be seen from the above technical solution, the advantages and positive effects of the intelligent interlocking control device proposed in this application are as follows:

[0017] The intelligent interlocking control device proposed in this application is equipped with a first sensor for detecting the connection status of the connector between the aircraft and the external device, enabling real-time monitoring of the connection status.

[0037] See Figure 1 The intelligent interlocking control device 1 of this application is mainly used for connecting the aircraft external equipment 2 and the boarding bridge 3. The intelligent interlocking control device 1 includes a first sensor 10 and a controller 20. The first sensor 10 is used to detect the connection status of the connection joint 5 between the aircraft 4 and the aircraft external equipment 2, and generate connection status parameters. The controller 20 is used to receive the connection status parameters and generate execution commands based on the received parameters. The execution commands are used to perform interlocking control on the aircraft external equipment 2 and the boarding bridge 3.

[0038] The intelligent interlocking control device 1 of this application is equipped with a first sensor 10 for detecting the connection status of the connector 5 between the aircraft 4 and the external device 2, and can detect the connection status of the aircraft 4 and the external device 2 in real time. The connection status is generated into connection status parameters, which are then calculated by the controller 20 to generate execution commands. These execution commands are used to interlock and control the external device 2 and the boarding bridge 3. This effectively avoids operator error; it also greatly reduces the safety risks caused by the retraction of the boarding bridge 3 when the connector 5 is connected to the aircraft 4; and it reduces the requirements and workload for operators.

[0039] In this embodiment, the aircraft 4 can be an airplane, etc. The boarding bridge 3 is connected to the walking mechanism via a column. The walking mechanism can drive the boarding bridge 3 to move, so as to realize the docking and departure of the boarding bridge 3 from the aircraft 4. In this embodiment, the external device 2 of the aircraft is set on the boarding bridge 3. In some other embodiments, the external device 2 of the aircraft may not be set on the boarding bridge 3 and may be set separately from the boarding bridge 3.

[0040] In this embodiment, the controller 20 is mounted on a column above the walking mechanism. The controller 20 is electrically connected to the first sensor 10 via a cable.

[0041] In this embodiment, the external device 2 for the aircraft includes a ground air conditioning unit 2, which is connected to and located below the boarding bridge 3. The ground air conditioning unit 2 can be connected to the boarding bridge 3 via multiple connecting rods. The controller 20 also receives status signals from the ground air conditioning unit 2 and generates execution commands based on the received signals. These execution commands are used for human-machine interaction. The controller 20 and the ground air conditioning unit 2 are electrically connected via cables. Human-machine interaction includes alarms and prompts. After receiving the execution commands (alarms or prompts) generated by the controller, the operator will perform relevant operations. After the operator's operation, the controller receives the parameters detected by various sensors, thus providing feedback on the operator's actions to the controller, thereby realizing human-machine interaction.

[0042] In this embodiment, when the status signal of the ground air conditioning unit 2 is "running," the boarding bridge 3 is connected to the aircraft 4, and the connection joint 5 between the ground air conditioning unit 2 and the aircraft 4 is in a connected state, meaning the ground air conditioning unit 2 is supplying fresh air to the aircraft 4. If the first sensor 10 detects that the connection joint 5 has changed from a connected state to a disconnected state, it executes commands including an alarm command to alert the operator. When the ground air conditioning unit 2 is supplying fresh air to the aircraft 4, it is necessary to ensure that the connection joint 5 is always in a connected state. If the connection joint 5 disconnects during the process of the ground air conditioning unit 2 supplying fresh air to the aircraft 4, it indicates a connection failure, and the controller 20 issues an alarm to remind the operator to check and troubleshoot the fault.

[0043] In this embodiment, when the status signal of the ground air conditioning unit 2 is "stop," it means that the ground air conditioning unit 2 has already provided sufficient fresh air to the aircraft 4, and the aircraft 4 does not need the ground air conditioning unit 2 to provide further fresh air. At this moment, the boarding bridge 3 remains in its original docked state with the aircraft 4, and the connection joint 5 between the ground air conditioning unit 2 and the aircraft 4 is in a connected state. If the first sensor 10 detects that the connection joint 5 is in a connected state, it executes a command including a prompt command to remind the operator to disconnect the connection joint 5. After the ground air conditioning unit 2 has provided sufficient fresh air to the aircraft 4, the controller 20 receives the signal from the ground air conditioning unit 2 and the status parameters of the first sensor 10, calculates the coordination relationship between the boarding bridge 3, the ground air conditioning unit 2, and the connection joint 5, and then issues a prompt command to remind the operator to disconnect the connection joint 5.

[0044] In this embodiment, the ground air conditioning unit 2 is connected to the aircraft 4 via a duct 21, which is used to deliver fresh air generated by the ground air conditioning unit 2 into the aircraft 4. The duct 21 is typically a flexible hose, and the electrical connection cable between the first sensor 10 and the controller 20 can be fixed to the duct 21.

[0045] See Figure 2 In this embodiment, the first sensor 10 includes a switching element and is disposed on the connector 5. The switching element can be a magnetic induction switching element, a capacitive switching element, an inductive switching element, or a photoelectric switching element. The first sensor 10 can also be selected from other types of switching elements. In fact, the first sensor 10 can use a switching element that can detect both "open" and "closed" states, such as a pulse switching element.

[0046] In this embodiment, when the first sensor 10 detects that the connector 5 is in a connected state, the command executed includes a locking command to lock the boarding bridge 3, so that the boarding bridge 3 is in a connected state to the aircraft 4.

[0047] When the first sensor 10 detects that the connection connector 5 is in a connected state, the ground air conditioning unit 2 may be in one of the following three states:

[0048] 1. Prepare to start providing fresh air to aircraft 4;

[0049] 2. Currently providing fresh air to aircraft 4;

[0050] 3. Sufficient fresh air has been provided to aircraft 4, and it is now shut down.

[0051] In the first state described above, the ground air conditioning unit 2 is in an imminent start-up state. If the operator mistakenly evacuates the boarding bridge 3 at this time, damage to the aircraft 4, the ground air conditioning unit 2, the connecting joint 5, and the air duct 21 may occur, and other operational accidents may also occur. Therefore, it is necessary to interlock and lock the boarding bridge 3 at this time to ensure that no accidents occur, avoid damage, and save energy and reduce emissions.

[0052] In the second state described above, the ground air conditioning unit 2 is in operation, supplying fresh air to the aircraft 4 through duct 21 and connector 5. If the operator mistakenly evacuates the boarding bridge 3 at this time, damage to the aircraft 4, the ground air conditioning unit 2, connector 5, and duct 21 may occur, wasting energy and causing safety accidents. Therefore, it is necessary to interlock and lock the boarding bridge 3 at this time to ensure safe operation and improve work efficiency.

[0053] In the third state described above, the ground air conditioning unit 2 has just stopped operating, and the connecting joint 5 is still connected. If the operator mistakenly evacuates the boarding bridge 3 at this time, damage to the aircraft 4, the connecting joint 5, and the air duct 21 may occur, and other operational accidents may also occur. Therefore, it is necessary to interlock and lock the boarding bridge 3 at this time to ensure that no accidents occur and to avoid damage.

[0054] See Figure 1 and Figure 3 In this embodiment, the intelligent interlocking control device 1 further includes a second sensor 30, which is used to detect the retraction status of the connector 5 and generate retraction status parameters. The controller 20 receives the retraction status parameters and generates an execution command, which is used to perform interlocking control on the aircraft external equipment 2 and the boarding bridge 3. The second sensor 30, used to detect the retraction status of the connector 5, can detect the retraction status of the connector 5. Based on the retraction status of the connector 5, the controller 20 performs interlocking control on the ground air conditioning unit 2 and the boarding bridge 3, which can further enhance interlocking control and improve the overall operational safety. It can also further reduce the risk of accidents caused by operator error, ensuring the interlocking relationship between the boarding bridge 3, the ground air conditioning unit 2, and the connector 5, which is beneficial to improving work efficiency and reliability.

[0055] In this embodiment, the ground air conditioning unit 2 also includes a duct retractor 22, and the second sensor 30 is disposed on the duct retractor 22. The duct retractor 22 can be connected to the upright of the walking mechanism of the boarding bridge 3, or it can be disposed in other locations, or it can be disposed independently. The second sensor 30 is electrically connected to the controller 20 via a cable. The second sensor 30 includes a switching element, which can be a magnetic induction switching element, a capacitive switching element, an inductive switching element, or a photoelectric switching element. Other types of switching elements can also be selected for the second sensor 30. In practice, the second sensor 30 only needs to be able to detect both "open" and "closed" states, for example, a pulse switching element.

[0056] In this embodiment, when the second sensor 30 detects that the retracted state of the connector 5 is not retracted, the command executed includes a locking command to lock the boarding bridge 3, so that the boarding bridge 3 is in the state of being connected to the aircraft 4.

[0057] When the second sensor 30 detects that the retracted state of the connector 5 is not retracted, the state of the connector 5 can be divided into two cases:

[0058] 1. When the connection joint 5 is in the connected state, the ground air conditioning unit 2 is in three different states, which have been explained in detail above and will not be repeated here.

[0059] 2. When connector 5 is disconnected, the ground air conditioning unit 2 has stopped operating and will not provide fresh air to aircraft 4. The duct 21 begins to retract from the connection point on aircraft 4. However, connector 5 has not yet reached the retracted state. At this time, the first sensor 10 detects that connector 5 is disconnected, while the second sensor 30 detects that connector 5 has not yet reached the duct retractor 22, indicating that connector 5 is in the process of retracting. During this process, operators may evacuate boarding bridge 3. Once boarding bridge 3 begins to evacuate, damage to connector 5 and duct 21 may still occur because duct 21 is not fully retracted, potentially causing other operational accidents. Therefore, boarding bridge 3 needs to be interlocked and locked at this time to ensure no accidents occur and damage is avoided.

[0060] The second sensor 30 further enables interlocking control of the boarding bridge 3. The controller 20 generates a locking command to lock the boarding bridge 3, achieving safe operation and preventing abnormal evacuation of the boarding bridge 3 due to operator error or misoperation. This further improves the reliability of operation and reduces the requirements for operators.

[0061] In this embodiment, the controller 20 may include a data acquisition unit and a calculation unit. The data acquisition unit is used to acquire data detected by the first sensor 10 and the second sensor 30. The calculation unit is used to make judgments and calculations based on the acquired data to derive an execution command. The execution command can be sent to the execution unit for execution. The execution unit can be set in the controller 20 or set separately.

[0065] The intelligent interlocking control device 1 of this application also has a fifth embodiment, wherein the intelligent interlocking control device 1 of the fifth embodiment is related to... Figures 1 to 3 Compared to the intelligent interlocking control device 1 of the previous embodiment, it has a substantially similar structure in its basic construction.

Figures 1 to 3 The differences between the intelligent interlocking control device 1 in this fifth embodiment and the previous one will be explained.

[0066] In fact, even when the controller 20 and the ground air conditioning unit 2 are electrically connected wirelessly, the first sensor 10 can also be electrically connected to the controller 20 wirelessly, and the second sensor 30 can be electrically connected to the controller 20 via cable. Alternatively, the first sensor 10 can be electrically connected to the controller 20 via cable, and the second sensor 30 can be electrically connected to the controller 20 wirelessly.

[0067] The above is a detailed description of several exemplary embodiments of the intelligent interlocking control device 1 proposed in this application. The following will describe in detail the usage process of the intelligent interlocking control device 1 proposed in this application.

[0068] Combined with appendix Figures 1 to 3 The usage process of the intelligent interlocking control device 1 proposed in this application is as follows:

[0069] First, the operator connects boarding bridge 3 to aircraft 4.

[0070] Afterwards, the operator removes the connector 5 from the duct retractor 22 and connects the duct 21 to the aircraft 4. At this time, the first sensor 10 detects that the connector 5 is in a connected state, and the controller 20 of the intelligent interlock control device 1 generates a locking command to lock the boarding bridge 3 and prevent the boarding bridge 3 from being removed.

[0071] Then, the ground air conditioning unit 2 is started manually or automatically to supply fresh air to the aircraft 4. During this process, the first sensor 10 detects that the connecting joint 5 is always connected and the boarding bridge 3 is always locked. If the first sensor 10 detects that the connecting joint 5 changes from connected to disconnected during this process, the surface air duct 21 and the aircraft 4 are disconnected, an accident has occurred, and the controller 20 will generate an alarm command to sound an alarm.

[0072] When the ground air conditioning unit 2 completes the supply of fresh air and triggers the shutdown state, the first sensor 10 detects that the connection connector 5 is still connected. The controller 20 can generate a prompt command to prompt the operator to disconnect the connection connector 5.

[0073] When the first sensor 10 detects that the connector 5 has been disconnected, and the second sensor 30 detects that the connector 5 has not yet been retracted into the duct 21 retractor, the controller 20 generates a locking command, and the boarding bridge 3 remains locked and cannot be evacuated.

[0074] When the second sensor 30 detects that the connector 5 has been retracted to the duct retractor 22, the duct 21 has been completely detached from the aircraft 4 and has been retracted. At this time, the operator can operate the boarding bridge 3 to evacuate.

[0075] The evacuation operation of boarding bridge 3 can be performed manually or automatically.

[0076] In summary, the intelligent interlocking control device proposed in this application includes a first sensor and a controller. The first sensor is used to detect the connection status of the connector between the aircraft and the external equipment and generate connection status parameters. The controller is used to receive the connection status parameters and generate an execution command based on the received parameters.

The intelligent interlocking control device proposed in this application can effectively avoid operator error; it can also greatly reduce the safety accidents caused by the retraction of the boarding bridge when the connector is connected to the aircraft; and it can also reduce the requirements for operators and reduce their workload.
