[0051] In addition, the technical features involved in different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0052] Aircraft refueling trucks are important ground special vehicles used by airports to refuel aviation fuel. Figure 1 As shown, in some embodiments, the aircraft refueling vehicle includes a cab 1, a chassis frame 9, upper equipment and a control device. The cab 1 is arranged on the chassis frame 9. The upper equipment includes an oil pumping system, an oil tank assembly and a lifting mechanism, etc. In order to realize the operation of the upper equipment, the upper equipment includes a plurality of actuators 2, and each actuator 2 is provided with a detection component 3, which is configured to detect the working status of the actuator 2.

[0053] like Figure 3 As shown, the control device includes: an internal controller 4 and an external controller 5. The internal controller 4 is located inside the cab 1, and the external controller 5 is located outside the cab 1. The internal controller 4 and the external controller 5 are connected by a wire 6. For example, the wire 6 may include a single wire or multiple wires, cables, or a bus. The external controller 5 is connected to multiple detection components 3 via wires 6, such as signal lines, and is configured to receive detection signals from the multiple detection components 3 and send them to the internal controller 4. The external controller 5 is also connected to multiple actuators 2 via wires 6. The external controller 5 is configured to receive control signals from the internal controller 4 to drive the multiple actuators 2 to operate.

[0054] The aircraft refueling vehicle of the disclosed embodiment is equipped with both an internal controller 4 located within the cab 1 and an external controller 5 located outside the cab 1. Multiple actuators and detection components on the aircraft refueling vehicle are connected to the external controller 5 via wires, which in turn are connected to the internal controller 4 via wires. As a result, detection signals obtained by the multiple detection components can be transmitted to the internal controller 4 via the external controller 5, allowing the internal controller 4 to adjust control signals based on the operating status of the multiple actuators or control whether the aircraft refueling vehicle should travel. Furthermore, control signals from the internal controller 4 can also be transmitted to the multiple actuators via the external controller 5 to control their operation.

[0055] For example, when the internal controller 4 receives a signal that the actuator is in working state, it needs to keep the aircraft refueling truck in a brake state. Due to the special environment and operation objects of aviation fuel replenishment, the vehicle needs to be kept braked during the entire vehicle operation to prevent safety accidents caused by abnormal vehicle movement during operation.

[0056] This setting method can reduce the number of wiring harnesses introduced from outside the cab into the cab, takes up less space, and does not require a large wiring opening on the cab, which is beneficial to the sealing of the cab. The thinner wiring harness makes the wiring more flexible and easy to layout, and can reduce the risk of more wires being exposed, thereby improving the reliability of the control device and further improving the safety of aircraft refueling truck operations.

[0057] In some embodiments, as Figure 4 and Figure 5 As shown, the external controller 5 includes a first sub-controller 51 and a second sub-controller 52. The first sub-controller 51 is connected to a portion of the plurality of actuators 2 and the plurality of detection components 3 via a wire 6, and the second sub-controller 52 is connected to the remaining portion of the plurality of actuators 2 and the plurality of detection components 3 via a wire 6.

[0058] Since the aircraft refueling truck needs to perform many functions, the number of actuators 2 and detection components 3 is large, resulting in more leads. By setting the external controller 5 as two separate sub-controllers, it is convenient for external layout and wiring, and the accuracy of wiring can also be improved.

[0059] Optionally, the first sub-controller 51 and the second sub-controller 52 may be arranged side by side at the same position in the vehicle, or may be arranged at different positions according to the positions of the actuator 2 and / or detection component 3 connected thereto, to facilitate wiring.

[0060] Optionally, during wiring, multiple actuators 2 may be connected to the first sub-controller 51 via wires 6, and multiple detection components 3 may be connected to the second sub-controller 52 via wires 6. Alternatively, some actuators 2 and their corresponding detection components 3 may be connected to the first sub-controller 51 via wires 6, and the remaining actuators 2 and their corresponding detection components 3 may be connected to the second sub-controller 52 via wires 6.

[0061] For an embodiment in which the external controller 5 includes a first sub-controller 51 and a second sub-controller 52, as shown in FIG. Figure 4 and Figure 5 The wire 6 between the internal controller 4 and the external controller 5 includes a first wire 61 and a second wire 62 .

[0062] like Figure 4As shown, the first sub-controller 51 is connected to the internal controller 4 via a first wire 61, and the second sub-controller 52 is connected to the first sub-controller 51 via a second wire 62. Thus, the second sub-controller 52 sends the received detection signal to the internal controller 4 via the first sub-controller 51, and the control signal sent by the internal controller 4 is sent to the second sub-controller 52 via the first sub-controller 51.

[0063] like Figure 5 As shown, the second sub-controller 52 is connected to the portion of the first wire 6 located outside the cab 1 via the second wire 6. As a result, the detection signals received by the first sub-controller 51 and the second sub-controller 52 are combined and sent to the internal controller 4 via the first wire 61. The control signals sent by the internal controller 4 are sent to the first sub-controller 51 and the second sub-controller 52 respectively according to the preset address allocation rules.

[0064] The wiring method of this embodiment can further reduce the number of wirings between the internal controller 4 and the external controller 5, making the wiring more flexible and easy to layout, and can reliably protect the wires, thereby improving the reliability of the control device and further improving the safety of the aircraft refueling truck operation.

[0065] Optionally, the first sub-controller 51 and the second sub-controller 52 may also be connected to the internal controller 4 via independent wires 6 respectively.

[0066] In some embodiments, the wire 6 between the internal controller 4 and the external controller 5 adopts a CAN bus. Each CAN bus includes two lines, CAN high and CAN low. Figure 4 and Figure 5 In the embodiment, the internal controller 4 and the external controller 5 are connected via only one CAN bus.

[0067] This embodiment is connected via the CAN bus, which is beneficial to reducing the number of wires and transmitting multiple signals. It also has the advantages of strong real-time performance, long transmission distance, strong anti-electromagnetic interference ability, and low cost.

[0068] In some embodiments, as Figure 1 As shown, the external controller 5 is mounted on the aircraft refueling truck's chassis frame 9. The chassis frame 9 is provided with a beam, upon which the external controller 5 can be mounted. This arrangement eliminates the need to alter the layout of the aircraft refueling truck's onboard equipment and prevents the operation of the external controller 5 from being affected by the operation of the onboard equipment.

[0069] In some embodiments, as Figure 1 and Figure 2As shown, the aircraft refueling truck further includes an explosion-proof box 10, and the external controller 5 is disposed within the explosion-proof box 10. During the refueling process, the aircraft refueling truck may experience fuel leakage, which may cause explosions in high-temperature environments. Placing the external controller 5 within the explosion-proof box 10 can protect it from explosions and improve operational reliability and safety.

[0070] In addition to the explosion-proof function, the explosion-proof box 10 can also achieve the dispersion of the wiring harness, so that the wires at the entrance of the explosion-proof box 10 are connected to multiple actuators 2 and multiple detection components 3 through multiple exits.

[0071] Furthermore, a protective cover is provided outside the explosion-proof box 10 , and the protective cover is used to be oil-proof and waterproof, so as to improve the reliability and safety of the operation of the external controller 5 .

[0072] like Figure 2 As shown, the aircraft refueling vehicle also includes a mounting bracket 11, which is mounted on the chassis frame 9 of the aircraft refueling vehicle. The explosion-proof container 10 is detachably suspended from the mounting bracket 11. Specifically, the mounting bracket 11 includes a bracket body and a mounting edge 111. The mounting edge 111 is provided with a second mounting hole 112 for fastening the mounting bracket 11 to the chassis frame 9 via fasteners. The mounting edge 111 is arranged vertically. The explosion-proof container 10 is provided with mounting lugs 101 on both sides. The mounting lugs 101 are provided with first mounting holes 102 for fasteners to suspend the explosion-proof container 10 from the mounting bracket 11.

[0073] In this embodiment, the explosion-proof box 10 is detachably mounted by means of the mounting bracket 11 , which makes it easy to disassemble and facilitate maintenance of the external controller 5 .

[0074] In some embodiments, the wiring 6 between the internal controller 4 and the external controller 5 is routed so as to bypass the engine of the aircraft refueling truck. If the cab 1 is located far from the installation location of the external controller 5, the wiring distance between the internal controller 4 and the external controller 5 is longer, allowing the wiring 6 to avoid the heat source of the engine and prevent damage to the wiring 6.

[0075] In some embodiments, as Figure 6 As shown, the control device further includes an indicator light assembly 7, which includes a plurality of interlock indicator lights 71, a total interlock indicator light 72, an overriding interlock indicator light 73, and a power take-off indicator light 74. When the indicator lights are on, they can remain on or flash.

[0076] A plurality of interlock indicator lights 71 are provided outside the cab 1 and are provided in one-to-one correspondence with the plurality of actuators 2. The interlock indicator lights 71 are configured to light up when receiving an interlock signal S sent when the corresponding actuator 2 is in operation. Figure 2As shown, multiple interlock indicator lights 71 can be installed on the explosion-proof box 10. For example, multiple holes can be opened in the explosion-proof box 10 to allow the interlock indicator lights 71 to be exposed through the holes. To facilitate observation by the operator, the explosion-proof box 10 can be located near one side of the chassis frame 9, with the interlock indicator lights 71 facing the side of the vehicle. The operator can observe the operating status of the tanker truck without entering the cab.

[0077] The main interlock indicator light 72 is located within the cab 1, for example, on the top of the cab 1, and is electrically connected to the internal controller 4. It is configured to illuminate when an illuminated interlock indicator light 71 appears. That is, as long as at least one actuator 2 is not in its home position, the main interlock indicator light 72 will illuminate. An interlock signal S is transmitted to the internal controller 4 via the external controller 5. The internal controller 4 determines whether the main interlock indicator light 72 is illuminated based on multiple interlock signals S. This configuration allows the operator in the cab 1 to quickly determine whether any actuator 2 is in its home position. If an actuator 2 is in its home position, the vehicle brakes are maintained.

[0078] The override interlock indicator light 73 is located within the cab 1, for example, on the top of the cab 1, and is electrically connected to the internal controller 4. The indicator light 73 is configured to illuminate even when the multiple actuators 2 have returned to their original positions but the multiple interlock indicator lights 71 remain illuminated, and to illuminate after the override interlock function is manually forcibly engaged. Upon manually forcibly engaging the override interlock function, the vehicle's brakes are released, allowing the vehicle to be driven to a repair location.

[0079] A power take-off indicator light 74 is located within cab 1, for example, on the top of cab 1, and is electrically connected to internal controller 4. The indicator light 74 is configured to illuminate when the aircraft refueling vehicle's engine is providing power to the plurality of actuators 2. Illumination of the power take-off indicator light 74 indicates that the engine is providing power to the actuators in the upper body equipment, and the vehicle needs to be braked.

[0080] This embodiment allows the operator to observe the operating status of the refueling truck from both outside and inside the cab 1, providing flexible and convenient observation. Furthermore, due to the unique environment and operational requirements of aviation fuel refueling, operating status signals are required to control the vehicle to remain stationary during operation to prevent safety accidents caused by abnormal vehicle movement during operation. Accurately understanding the operating status of the upper equipment improves the safety of aircraft refueling truck operations.

[0081] In some embodiments, the external controller 5 is configured to send interlock signals of the plurality of actuators 2 to the internal controller 4, and the internal controller 4 is configured to release the brakes of the aircraft refueling truck when the override interlock indicator light 73 is on, and to brake the aircraft refueling truck when the power take-off indicator light 74 is on.

[0082] This embodiment ensures that the vehicle remains in a braked state when any actuator in the upper equipment is not in its original position or when the engine is providing power to the upper equipment, thereby improving the safety of the aircraft refueling vehicle. Furthermore, if multiple actuators 2 have been returned to their original positions but multiple interlock indicator lights 71 remain illuminated, the aircraft refueling vehicle can be released from its brakes for maintenance by manually forcibly opening the override interlock.

[0083] In some embodiments, as Figure 6 As shown, the control device also includes: multiple switching amplifiers 8, which are configured to amplify the interlocking signal S; the interlocking signals S emitted when the multiple actuators 2 are in action are all electrically connected to the external controller 5 after passing through a switching amplifier 8, and multiple interlocking indicator lights 71 are connected to the multiple switching amplifiers 8 in a one-to-one correspondence.

[0084] This embodiment can generate an interlock signal S when the actuator 2 is actuated. The interlock signal S is amplified by the switching amplifier 8, allowing it to be more accurately captured by the external controller 5 or illuminated by the interlock indicator 71, thus preventing erroneous sensing of the interlock signal S. The amplified interlock signal S is simultaneously transmitted to the external controller 5 and the interlock indicator 71, directly controlling the state of the interlock indicator 71 through the switching amplifier 8. The external controller 5 can then transmit the received interlock signal S to the internal controller 4 via the wire 6, thereby controlling the vehicle's braking state.

[0085] Optionally, the interlock signals S generated by the multiple actuators 2 when in operation are all electrically connected to the external controller 5 through a switching amplifier 8, and the multiple interlock indicator lights 71 are all connected to the external controller 5. In this embodiment, the amplified interlock signal S is sent to the external controller 5, which then controls the state of the interlock indicator lights 71.

[0086] In some embodiments, the controller described above may be a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any appropriate combination thereof, for performing the functions described in the present disclosure.

[0087] The above description is merely an exemplary embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
