Description

Technical Field

[0001] This utility model relates to an excitation device, and more particularly to a wheel-mounted excitation device for civil aircraft ground testing. Background Technology

[0002] Ground testing of civil aircraft is a crucial step before flight testing, bearing the important responsibility of ensuring safety during taxiing, maiden flight, and subsequent flights. Wheel-mounted signals are one of the key elements in civil aircraft ground testing. These signals are typically obtained by detecting the aircraft's landing gear status through wheel-mounted proximity sensors (sometimes simply referred to as wheel-mounted sensors). They are the only important signals used by most aircraft systems to determine their air-to-ground status, directly affecting the control, calibration, and testing of aircraft systems. Therefore, in order to simulate the aircraft's actual flight conditions as closely as possible during ground testing, stimulating the aircraft's wheel-mounted signals to test relevant aircraft systems is indispensable.

[0003] Currently, the excitation of wheel-borne signals in civil aircraft ground tests is often achieved by inputting simulated wheel-borne signals into the relevant control system of the aircraft or by using a separately manufactured simulation device to simulate the landing gear status.

[0004] However, there is currently little research on how to drive wheel-mounted sensors on aircraft, and there is a lack of wheel-mounted excitation devices that can stimulate the wheels of real aircraft to simulate the actual flight state of the aircraft, resulting in relatively low authenticity, accuracy and efficiency of civil aircraft ground tests. Utility Model Content

[0005] This invention was made in view of the above-mentioned problems, and its purpose is to provide a wheel-mounted excitation device for civil aircraft ground testing that can excite the actual wheel-mounted components.

[0006] To achieve the above objectives, this utility model provides a wheel-mounted excitation device, comprising: an excitation unit that excites a wheel-mounted proximity sensor on an aircraft to generate a wheel-mounted signal by approaching or moving away from the wheel-mounted proximity sensor; a fixing unit that fixes the wheel-mounted excitation device relative to the wheel-mounted proximity sensor; and a control unit that controls the excitation unit to approach or move away from the wheel-mounted proximity sensor.

[0007] According to the wheel-mounted excitation device of this invention, the excitation unit in the device can be controlled to approach or move away from the wheel-mounted proximity sensor on the aircraft and excite the wheel-mounted proximity sensor to generate a wheel-mounted signal. Compared with the previous use of simulated wheel-mounted signals for civil aircraft ground tests, it can obtain real wheel-mounted signal excitation, improving the authenticity and accuracy of civil aircraft ground tests. Furthermore, by reducing the process of connecting simulated signals to various components on the aircraft for wheel-mounted signals, the efficiency of civil aircraft ground tests is improved. In addition, by actually exciting the wheel-mounted proximity sensor using the excitation unit, the operating status of the wheel-mounted proximity sensor on the aircraft can be detected simultaneously.

[0008] Furthermore, in the wheel-mounted excitation device of this utility model, preferably, the excitation unit includes a servo motor and a baffle that rotates integrally with the servo motor, and the control unit controls the servo motor to rotate so that the baffle rotates to a position close to or away from the wheel-mounted proximity sensor.

[0009] Furthermore, in the wheel-mounted excitation device of this invention, it is preferable that the control unit can control the rotation of the servo motor based on control signals received via remote communication.

[0010] According to the above-described wheel-mounted excitation device, the baffle can be remotely controlled to rotate to approach or move away from the wheel-mounted proximity sensor. As a result, the personnel conducting civil aircraft ground tests can remotely control the device to excite the wheel-mounted proximity sensor to generate a wheel-mounted signal. While exciting the wheel-mounted signal, they can observe the response results of various components on the aircraft to the wheel-mounted signal, thus improving the efficiency of ground test work.

[0011] Furthermore, in the wheel-mounted excitation device of this utility model, it is preferred that the fixing part includes a clamp capable of holding the wheel-mounted proximity sensor.

[0012] Furthermore, in the wheel-mounted excitation device of this utility model, preferably, the control unit includes a chip having a communication module and a control module, the communication module being able to receive the control signal through remote communication, and the control module being able to control the rotation of the servo motor based on the control signal.

[0013] Furthermore, in the wheel-mounted excitation device of this utility model, it is preferred to include a battery module, which can transmit power to the control unit and the servo motor.

[0014] Furthermore, in the wheel-mounted excitation device of this utility model, it is preferred to include a housing that houses the servo motor, the battery module, and the chip.

[0015] Furthermore, in the wheel-mounted excitation device of this invention, it is preferable that the battery module is rechargeable.

[0016] According to the wheel-mounted excitation device with the above structure, the wheel-mounted excitation device can be clamped to the wheel-mounted proximity sensor by the fixing part. Thus, the wheel-mounted excitation device can be easily connected to the wheel-mounted proximity sensor. Furthermore, by using a rechargeable battery module to power the various components in the device, the need for additional power supply equipment can be reduced, thereby reducing the additional wiring on the device and making it easy to assemble and disassemble the device.

[0017] (Utility Model Effect)

[0018] According to this invention, the wheel-mounted excitation device can control the excitation unit within the device to approach or move away from the wheel-mounted proximity sensor on the aircraft, thereby stimulating the sensor to generate a wheel-mounted signal. Compared to previous methods using simulated wheel-mounted signals in civil aircraft ground tests, this method obtains a realistic wheel-mounted signal excitation, improving the realism and accuracy of the ground tests. Furthermore, by reducing the steps involved in connecting simulated wheel-mounted signals to various aircraft components, the efficiency of civil aircraft ground tests is improved. Moreover, by simply connecting the wheel-mounted excitation device, which requires no additional power supply, to the wheel-mounted proximity sensor and controlling it remotely, the installation and control steps of the excitation device during testing are reduced, further improving efficiency. Additionally, by actually stimulating the wheel-mounted proximity sensor with the excitation unit, the operating status of the aircraft's wheel-mounted proximity sensor can be detected simultaneously.

[0034] The following description, in conjunction with the accompanying drawings, describes one embodiment of the present invention. Figure 1 This is a perspective view showing the components of the wheel-mounted excitation device constituting the embodiment in an exploded view. Figure 2 This is a schematic diagram showing the state in which the wheel-mounted excitation device of the embodiment is installed on the wheel-mounted sensor 11.

[0035] For ease of explanation, the following will be used as... Figure 1 The direction is described by the directional marker shown in the lower right corner.

[0036] like Figure 1 As shown, the wheel-mounted excitation device of this embodiment mainly includes a baffle 1, a servo motor 2, a spring 3, a chip 4, a housing 5, a movable clamp 6, a fixed clamp 10, a charging connector 7, a battery module 8, and a cover 9.

[0037] The servo motor 2 in this embodiment is a servo motor, which includes an output shaft connected to the baffle 1. Furthermore, the servo motor 2 also includes components commonly used in servo motors, such as a DC motor and a reduction gear set. Additionally, although not shown, the servo motor 2 also has a servo disc for connecting the output shaft to the baffle 1.

[0038] The movement of the servo motor 2 is driven and controlled by the chip 4. Here, the chip 4 is equivalent to the control unit of this invention. Specifically, the chip 4 in this embodiment is a common chip used for remote control that integrates functional modules such as a communication module, a judgment module, and a control module.

[0039] In this embodiment, the communication module integrated on chip 4 is a WiFi module that uses WiFi for wireless communication. It can communicate with the remote control system. Here, the remote control system is a terminal that can communicate with the communication module via WiFi, such as a computer, mobile phone, tablet computer, etc.

[0040] After receiving a control signal from the remote control system, the communication module transmits the signal to the judgment module. The judgment module demodulates the control signal and determines whether the signal is an approach control signal or a distance control signal (described later). Based on the judgment result, it generates a corresponding pulse width modulation (PWM) signal and transmits it to the control module.

[0041] The control module is electrically connected to the DC motor in the servo 2. The control module, for example, has a component that converts a pulse width modulation (PWM) signal into a DC bias voltage. After receiving a signal from the aforementioned judgment module, the control module converts the signal into a DC bias voltage and drives the DC motor in the servo 2 to rotate, thereby causing the output shaft of the servo 2 to rotate in a specified direction and angle.

[0042] Preferably, chip 4 also integrates a feedback control module. The rotational position of the servo motor 2 can be monitored through this feedback control module. The feedback control module can transmit the monitored rotational position information back to the communication module, and then the communication module sends the information to the remote control system. Therefore, even if ground test personnel are in a location such as inside the cabin where they cannot observe the wheel-mounted excitation equipment of this embodiment, they can still understand the rotational position of the servo motor 2 and the baffle 1 connected to the servo motor 2 through a readily available remote control system, thus improving work efficiency.

[0043] In this embodiment, the battery module 8 is, for example, a secondary battery such as a lithium-ion battery. It is electrically connected to the chip 4, supplies power to various functional modules on the chip 4, and can supply power to the servo motor 2 via the chip 4 to drive the servo motor 2 to rotate.

[0044] The battery module 8 is also electrically connected to the charging connector 7, which can be electrically connected to, for example, a power adapter or a power port on an electronic device to charge the battery module 8. Figure 1 The structure of the charging connector 7 is simplified and shown in this embodiment. In this embodiment, the charging connector 7 is a wire that is connected at one end to the charging interface on the battery module 8 and at the other end to the charging device. Here, the specifications of the charging connector 7 are not limited; it can be any common charging connector or a charging connector specially designed according to the application of the wheel-mounted excitation equipment.

[0045] In this embodiment, the baffle 1 is a metal sheet made of copper or a copper alloy, and when viewed along its thickness direction, it is a rectangle with rounded corners at all four corners. Multiple through holes are provided at one end of the baffle 1 along its length, through which screws can pass and connect to the output shaft of the servo motor 2 via the servo disc. When the servo motor 2 is driven to rotate by the control module, the baffle 1 can rotate integrally with the output shaft of the servo motor 2.

[0046] Furthermore, although the baffle 1 in this embodiment is made of copper or a copper alloy, it is not limited to this. For example, the baffle 1 can also be made of materials such as aluminum, aluminum alloy, steel, or titanium alloy. In addition, the baffle 1 is preferably made of a material with low density and good ductility. This reduces the weight of the baffle 1 as much as possible, thereby reducing the voltage required to drive the servo motor 2 to move the baffle 1. This reduces the power demand on the battery module 8 in the device, which is beneficial to improving the device's range. It also allows for a reduction in the size of the battery module 8 to achieve overall device miniaturization.

[0047] In this embodiment, the outer casing 5 is made of resin material such as polypropylene by injection molding. The outer casing 5 houses the servo motor 2, the chip 4, the charging connector 7, and the battery module 8.

[0048] Specifically, such as Figure 1 As shown, the interior of the rear end side of the outer casing 5 is divided into an upper storage section and a lower storage section by a plate. The upper storage section can be used to store the battery module 8, and the lower storage section can be used to store the chip 4.

[0049] On the inner walls of the left and right sides of the lower storage section, there are grooves for inserting and guiding the chip 4. Specifically, a pair of raised strips arranged vertically are formed on the inner walls of the left and right sides of the lower storage section. The two pairs of raised strips are positioned exactly the same relative to the inner wall on their respective sides. The raised strips extend in the front-back direction and protrude from each other on the left and right inner walls, allowing the chip 4 to be placed on the raised strips. In addition, the interval between the two raised strips in a pair is slightly greater than the thickness of the chip 4, and in the front-back direction, the length of each raised strip is greater than the length of the chip 4. Thus, the two pairs of raised strips form a groove for inserting the chip 4, and the chip 4 can be inserted into the groove from the opening at the rear end of the outer casing 5 and moved in the front-back direction under the guidance of the groove.

[0050] The battery module 8 can be inserted into the upper storage compartment through the rear opening of the outer casing 5. Furthermore, although in Figure 1 Although not shown in the diagram, a through hole is formed on the left side wall of the upper storage section for the charging connector 7 to pass through. When the battery module 8 is stored in the upper storage section, the charging connector 7 can pass through the through hole and connect to the battery module 8.

[0051] After the battery module 8 and chip 4 are placed inside the housing 5, the rear opening of the housing 5 is closed by the cover 9, thereby storing the battery module 8 and chip 4 inside the housing 5.

[0052] In this embodiment, the servo motor 2 is housed at the front end of the housing 5. Specifically, an opening for inserting the servo motor 2 is formed at the front end of the lower surface of the housing 5, allowing the servo motor 2 to... Figure 1The servo motor 2 is inserted into the housing 5 through the opening as shown in the diagram, and then the opening is closed with a component such as a cover, thereby housing the servo motor 2 within the housing 5. Here, before closing the opening, the servo motor 2 is connected to the chip 4 through the opening; specifically, the DC motor of the servo motor 2 is connected to the control module on the chip 4.

[0053] In addition, such as Figure 1 As shown, a square hole is formed on the upper surface of the housing 5 for the output shaft of the servo motor 2 to extend. The output shaft of the servo motor 2 can extend through the square hole to a position above the upper surface of the housing 5 and connect to the baffle 1 via the servo disc.

[0054] The wheel-mounted excitation device in this embodiment also includes a clamp for holding the wheel-mounted sensor 11. For example... Figure 1 As shown, the clamp includes a fixed clamp handle 10, a movable clamp handle 6 connected to the fixed clamp handle 10, and a spring 3.

[0055] The fixing handle 10 is integrally formed with the outer shell 5 on the right side of the outer shell 5. A clamping part is formed at the right end of the fixing handle 10. When viewed from above, the clamping part is formed as a semi-circle that is recessed from the rear end to the front.

[0056] The movable clamp 6 is connected to the fixed clamp 10 via a hinge, for example, and can rotate relative to the fixed clamp 10 about the hinge axis.

[0057] The movable clamp 6 has a clamping portion and a handle portion. When viewed from above, the clamping portion of the movable clamp 6 is a semi-circular shape that is concave from the front end to the rear, and the shape of the clamping portion of the movable clamp 6 corresponds to the shape of the handle portion of the fixed clamp 10. Here, the shape and size of the clamping portions of the two clamps can be specifically selected according to the shape of the wheel-mounted sensor 11 actually clamped by the wheel-mounted excitation device, thereby enabling the wheel-mounted excitation device to be fixed relative to the wheel-mounted sensor 11 by clamping the clamp onto the wheel-mounted sensor 11.

[0058] The handle is for the operator to operate the movable clamp 6. A hook structure for the spring 3 is provided on the rear end face of the handle and the right end face of the outer casing 5. The two ends of the spring 3 are hooked to the outer casing 5 and the handle of the movable clamp 6, respectively. Here, with the two clamps of the fixture gripping the wheel-mounted sensor 11, the spring 3 is in a compressed state, pressing the movable clamp 6 towards the fixed clamp 10 through its elastic force, thus clamping the fixture. After the test is completed, the operator can operate the handle to separate the movable clamp 6 from the fixed clamp 10 to remove the wheel-mounted excitation device from the wheel-mounted sensor 11.

[0059] Before describing the method of using the wheel-mounted excitation device of this embodiment, the wheel-mounted sensor 11, which is the application object of the wheel-mounted excitation device of this embodiment, will be briefly described first.

[0060] like Figure 2 As shown, the wheel-mounted sensor 11 has a cylindrical body, and a detection element for detecting whether a target object is approaching is provided at one end of the body along its length. This detection element is, for example, an ohmic reactance. When the target, which serves as the wheel-mounted sensor 11, approaches or moves away from the detection element, the reactance changes, thereby exciting an approach signal or a departure signal, which are wheel-mounted signals. For the wheel-mounted sensor 11 on the aircraft landing gear, when an approach signal is generated, the system acquires the signal and determines that the landing gear is retracted and the aircraft is in flight. Conversely, when a departure signal is generated, the system determines that the landing gear is deployed and the aircraft is on the ground.

[0061] The following is based on the above explanation and in conjunction with Figure 3 The usage process of the wheel-mounted excitation device in this embodiment will be explained.

[0062] When using the wheel-mounted excitation device of this embodiment, firstly, the clamp on the device is clamped in a suitable position. Specifically, when clamping the wheel-mounted excitation device to the wheel-mounted sensor 11, the clamp is clamped on the main body of the wheel-mounted sensor 11, and the clamping position is adjusted until the baffle 1 of the wheel-mounted excitation device can rotate to a position that can approach the detection element and excite the wheel-mounted sensor 11 to generate a wheel-mounted signal.

[0063] After clamping the wheel-mounted excitation device in the appropriate position, the operator can control the operation of the wheel-mounted excitation device through the remote control system.

[0064] Specifically, the staff can use the remote control system to send a control signal to the chip 4 of the wheel-mounted excitation device via WiFi communication. The communication module on the chip 4 receives the control signal and transmits it to the judgment module for judgment. Then, based on the judgment result, the module sends a PWM signal to the control module on the chip 4. The control module converts the PWM signal into a DC bias voltage to drive the DC motor of the servo 2 to rotate, thereby causing the baffle 1 connected to the servo 2 to rotate to the required position.

[0065] Here, the positions to which the baffle 1 is rotated by the remote control system mainly include the approach position and the distance position. At the approach position, the baffle 1 can block the detection element of the wheel-mounted sensor 11 to excite the wheel-mounted sensor 11 to generate an approach signal. At the distance position, the baffle 1 does not block the detection element to excite the wheel-mounted sensor 11 to generate a distance signal.

[0066] Therefore, during civil aircraft ground testing, personnel can send control signals to the wheel-mounted excitation device of this embodiment via a remote control system from inside the cabin. When the sent control signal is a proximity control signal, the servo motor 2 drives the baffle 1 to rotate to the proximity position. The baffle 1 blocks the detection element of the wheel-mounted sensor 11. At this time, the wheel-mounted sensor 11 detects the target approach and generates a proximity signal as a wheel-mounted signal. The aircraft's flight control system and other systems should determine based on this proximity signal that the aircraft's landing gear has retracted and the aircraft is in flight. During civil aircraft ground testing, personnel can test various functions of the aircraft by checking whether the flight control system and other systems respond normally and whether various equipment on the aircraft are controlled to the operating mode of flight status. Among them, the operating modes of various equipment on the aircraft in flight status include, for example, activating the automatic fuel balance system in the fuel system and triggering the oxygen supply system in the cabin system.

[0067] Conversely, when the transmitted control signal is a distance control signal, the servo motor 2 drives the baffle 1 to rotate to the distance position. The baffle 1 moves away and no longer obstructs the detection element of the wheel-mounted sensor 11. At this time, the wheel-mounted sensor 11 detects that the target has moved away and generates a distance signal as a wheel-mounted signal. Based on this distance signal, the aircraft's flight control system determines that the landing gear has been lowered and the aircraft is in a landing state. During ground testing of civil aircraft, personnel can test various functions of the aircraft by checking whether the flight control system responds normally and whether various equipment on the aircraft is controlled to the operating mode of the landing state. The operating modes of various equipment on the aircraft in the landing state include, for example, activating thrust reversers in the engine system and executing decompression procedures in the cabin system.

[0068] Therefore, the wheel-mounted excitation device according to this embodiment can excite the wheel-mounted sensor 11 to generate corresponding wheel-mounted signals by remotely controlling a physical structure such as the baffle 1, thereby testing and detecting the operating status of various devices on the aircraft in response to the wheel-mounted signals. Furthermore, even if personnel are in a location such as inside the cabin where they cannot visually see the wheel-mounted excitation device, they can still understand the rotation of the baffle 1 through the device's feedback control function. Therefore, compared to conventional methods that input analog signals for wheel-mounted signals, by comparing the rotation of the baffle 1 with the response results of the wheel-mounted sensor 11, the operating status of the wheel-mounted sensor 11 on the aircraft can be detected simultaneously.

[0069] (Main effects of this implementation method)

[0070] According to this embodiment, the wheel-mounted excitation device can control the baffle 1 in the device to rotate to a position close to or away from the wheel-mounted sensor 11 on the aircraft and excite the wheel-mounted sensor 11 to generate a wheel-mounted signal. Compared with the conventional use of simulated wheel-mounted signals in civil aircraft ground tests, obtaining real wheel-mounted signal excitation by physically exciting the wheel-mounted sensor 11 improves the realism and accuracy of civil aircraft ground tests. Furthermore, by reducing the process of connecting simulated signals to various components on the aircraft and using WiFi communication for remote control, it is possible to observe the response of various components on the aircraft to the real wheel-mounted signal while controlling the excitation of the wheel-mounted signal, thus improving the efficiency of civil aircraft ground tests. Moreover, the wheel-mounted excitation device of this embodiment is clamped to the wheel-mounted sensor 11 by a simple clamp and powered by the built-in battery module 8, thereby simplifying the installation process of the wheel-mounted excitation device during testing and further improving ground test efficiency. In addition, by actually exciting the wheel-mounted sensor 11 using the baffle 1, the operating status of the wheel-mounted sensor 11 on the aircraft can be detected simultaneously.

[0071] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above embodiments.

[0072] For example, in the above embodiment, the baffle 1 is connected to the servo motor 2 and rotates to approach or move away from the wheel sensor 11 to excite the wheel sensor 11, but it is not limited to this. For example, the baffle 1 may also be connected to a linear motor capable of linear motion, and move towards or away from the wheel sensor 11 through linear motion to excite the wheel sensor 11 to generate a wheel signal.

[0073] Furthermore, in the above embodiments, the clamp includes a fixed clamping handle integrally formed with the housing 5 and a movable clamping handle independent of the housing 5, but the structure of the clamp is not limited to this. For example, the clamp may also consist of two clamping handles independent of the housing 5, and either of these clamping handles can be connected to the housing 5 to clamp the wheel-mounted excitation device onto the wheel-mounted sensor 11. In this case, the spring 3 may be a clamping spring disposed near the hinge connecting the two clamping handles, which applies force to the two clamping handles in the clamping direction to clamp the wheel-mounted sensor 11.

[0074] Furthermore, the clamp is not limited to the spring-based clamp described above. For example, the clamp can also be a faucet clamp that uses screws and nuts to fasten two clamping blocks to achieve clamping. The two clamping blocks also have clamping parts formed on them, corresponding to the shape of the wheel-mounted sensor 11. One of the two clamping blocks can be integrally formed with the housing 5, and the other can be independent of the housing 5. Alternatively, both clamping blocks can be independent of the housing 5, and either one of them can be connected to the housing 5.

[0075] Furthermore, in the above embodiment, the clamp is held on the wheel-mounted sensor 11, but it is not limited to this. The clamping position of the clamp is only required to allow the baffle 1 to rotate to a close position. For example, it can also be clamped on a structure near the wheel-mounted sensor 11.

[0076] Furthermore, in the above embodiments, the wheel-mounted excitation device is fixed relative to the wheel-mounted sensor 11 by a clamp, but it is not limited to this. For example, the wheel-mounted excitation device can also be fixed relative to the wheel-mounted sensor 11 by means of bonding, hanging, magnetic adsorption, etc.

[0077] Furthermore, in the above embodiment, the communication module on chip 4 is a WiFi communication module, but it is not limited to this. For example, the communication module could also be a Bluetooth communication module, or a 2.4GHz wireless communication technology module. Additionally, in environments with significant wireless signal interference, the control system could communicate with chip 4 via wired communication, for example, the operator's control terminal could be connected to chip 4 via a cable of appropriate length.

[0078] Furthermore, in the above embodiments, chip 4, which integrates multiple functional modules such as a communication module and a control module, is used as the control unit of the wheel-mounted excitation device, but it is not limited to this. For example, from the perspective of reducing the heat generation on a single chip, the control unit may also be configured to include one or more components independent of chip 4, in addition to chip 4, which also have functional modules such as a control module. Preferably, chip 4 and these components are arranged at intervals to help prevent malfunctions or other adverse situations caused by high heat generation of the device.

[0079] Furthermore, in the above embodiment, the battery module 8 is housed in the upper layer and the chip 4 is housed in the lower layer within the housing 5, with the servo motor 2 inserted into the housing 5 from below. However, this is not a limitation; the arrangement of the components constituting the wheel-mounted excitation device within the housing 5 can be appropriately modified according to actual circumstances. For example, the battery module 8 may be housed in the lower layer and the chip 4 in the upper layer. Alternatively, the housing 5 may have a partition separating the internal space horizontally, with the battery module 8 and chip 4 arranged in the left-right direction. Or, there may be no partition, with the battery module 8 and chip 4 appropriately arranged to ensure heat dissipation.

[0080] The servo motor 2 can be placed inside the housing 5 from various directions such as above, left or right sides, and the through hole for the charging connector 7 to pass through can also be set on any surface of the housing 5 as needed.

[0081] In addition, in order to increase the flexibility of the above-mentioned components, the outer shell 5 is preferably made of multiple plates of different shapes and sizes bonded together, rather than being formed as a single piece by injection molding.

[0082] It should be understood that within the scope of this invention, the various parts of the embodiments can be freely combined, or the various parts of the embodiments can be appropriately modified or omitted.
