Description

Technical Field

[0001] This invention relates to sensor function testing in the field of aircraft, and particularly to a device for testing a single-wind vane angle-of-attack sensor. Background Technology

[0002] A wind vane angle-of-attack sensor is a device used to measure the direction of airflow. Based on aerodynamics and thermodynamics, it calculates airflow conditions by measuring the force and direction of the airflow acting on a wind vane. The wind vane angle-of-attack sensor mainly consists of a wind vane and a measurement module. The wind vane has excellent directional sensing capabilities. The measurement module includes force sensors, accelerometers, and angle sensors, used to measure the force and angle of the airflow. Wind vane angle-of-attack sensors have wide applications in aviation, marine, and automotive industries. In aviation, they are widely used for aircraft attitude control, aerodynamic performance testing, and data acquisition; in marine applications, they are used in navigation and steering control systems. Furthermore, wind vane angle-of-attack sensors are also used in meteorology and aerodynamics.

[0003] Angle-of-attack (AOA) sensors are generally classified into single-anchor and dual-anchor types. Single-anchor AOA sensors are typically installed on either side of the nose of an aircraft, measuring the aircraft's pitch angle by sensing airflow. Their performance directly impacts the quality and safety of aircraft and related systems. However, currently, there is no dedicated automated testing device for single-anchor AOA sensors. In some countries, only visual inspection is performed, without corresponding functional performance verification. This results in incomplete, inaccurate, costly, and inefficient testing of AOA sensors, making it difficult to detect sensor malfunctions promptly and severely impacting aspects such as aircraft manufacturing and flight testing. Therefore, a dedicated AOA sensor functional testing device needs to be designed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a device for testing a single-wind vane angle-of-attack sensor, which at least partially solves the problems in the prior art.

[0005] The objective is achieved by an apparatus for testing a single-wind vane angle-of-attack sensor according to the present invention. According to the present invention, the apparatus comprises: a test module operably connected to the angle-of-attack sensor and configured to test various functions of the angle-of-attack sensor; a data acquisition module including a communication unit capable of communicating with the angle-of-attack sensor; a central control module connected to the test module and the communication unit and configured to control the operation of the test module and the angle-of-attack sensor; and a calculation and analysis unit integrated within the angle-of-attack sensor, configured to calculate and analyze data from the angle-of-attack sensor and the central control module.

[0006] This invention enables comprehensive component-level manual / automatic testing of single-wind-marker angle-of-attack sensors, efficiently and accurately performing functional testing and fault location, reducing the testing and troubleshooting costs of the corresponding interconnected systems, and meeting the testing application needs of multiple scenarios such as aircraft ground assembly and flight testing.

[0007] In one embodiment of the invention, the test module includes an interface unit, a power supply unit, and a fixing and rotating unit. The interface unit is configured to provide various test interfaces, control interfaces, and power interfaces. The power supply unit is configured to power the test module and the angle-of-attack sensor. The fixing and rotating unit is configured to reliably mount the angle-of-attack sensor and rotate the anemometer mounted on it. In this way, the angle-of-attack sensor can be mounted, fixed, and powered, enabling the anemometer to rotate and providing the basic physical conditions for various tests and controls.

[0008] In one embodiment of the invention, the interface unit includes a front interface panel and a rear interface panel. The front interface panel is provided with a front test interface configured to facilitate manual single-item testing, and the rear interface panel is provided with a rear test interface configured to facilitate automatic full-item testing. Here, as part of a single-item test, the front test interface performs bypass testing on the interface pins of the single-wind vane angle-of-attack sensor, thereby supplementing and refining fault location. This enables flexible testing of the angle-of-attack sensor, allowing for both individual manual testing and fault location of a specific function, as well as automatic full-item testing of all functions, thus improving testing efficiency.

[0009] In one embodiment of the present invention, the communication unit includes a discrete data transmission unit and an ARINC429 bus data transmission unit. The discrete data transmission unit and the ARINC429 bus data transmission unit enable the interaction of discrete and bus signals between the angle-of-attack sensor and the central control module, thereby achieving functions such as angle-of-attack sensor operating state switching, aircraft air and ground environment simulation, automatic ignition, and stall warning via stick push-to-start.

[0010] In one embodiment of the present invention, the data acquisition module further includes a resistance measuring unit configured to measure the resistance value of the built-in circuit of the angle-of-attack sensor. Using the resistance value of the built-in circuit of the angle-of-attack sensor measured by this resistance measuring unit, and in conjunction with the status bit information regarding heating failure in the ARINC429 bus data, the heating failure function test of the angle-of-attack sensor's wind vane can be completed collaboratively.

[0011] In one embodiment of the present invention, the power supply unit can flexibly adjust the supply voltage according to different test items. Different test items may require different supply voltages, such as 220V, 28V, etc., for driving, heating, etc. Therefore, the power supply unit can be used to provide corresponding voltages for different test items to meet different test requirements.

[0012] In one embodiment of the invention, the fixing and rotating unit includes a bracket configured to support the angle-of-attack sensor and a fixing member configured to fix the angle-of-attack sensor. Here, the bracket supports the angle-of-attack sensor, and the fixing member secures it, thereby mechanically ensuring the angle-of-attack sensor operates stably and preparing it for subsequent functional testing.

[0013] In one embodiment of the invention, the bracket prevents the weather vane from contacting the top surface of the test module. This is done to ensure that during functional testing of the angle-of-attack sensor, or in other words, during the rotation of the weather vane, the weather vane will not come into contact with or rub against the test module, thus preventing the angle-of-attack sensor from malfunctioning due to mechanical failure of the weather vane.

[0014] In one embodiment of the invention, the fixing and rotating unit further includes a coupling sleeve fixedly connected to the weather vane, the coupling sleeve engaging with a drive shaft in the test module. Here, driven by the drive shaft, the coupling sleeve rotates, thereby causing the weather vane to rotate, simulating the rotational motion of the weather vane when pushed by airflow, thus activating the angle of attack sensor and performing functional testing on the angle of attack sensor.

[0015] In one embodiment of the invention, the fixing and rotating unit further includes a protective cover configured to protect the coupling sleeve and the weather vane. The protective cover protects the coupling sleeve and weather vane from external influences during operation, particularly preventing interference from foreign objects, thereby ensuring the smooth conduct of the angle-of-attack sensor functional testing.

[0023] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments based on this application; those skilled in the art can conceive of other ways to implement this application based on the preferred embodiments, and such other ways also fall within the scope of this application.

[0024] The following is combined Figures 1 to 6 A detailed description of the apparatus for testing a single-wind vane type angle of attack sensor 40 according to the present invention. See also Figure 1 This is a functional block diagram of the device, such as... Figure 1 As shown, the device mainly includes a testing module 10, a central control module 20, and a data acquisition module 70. Furthermore, the device... Figure 1 It can also be seen that the device also includes a calculation and analysis unit 7 integrated inside the angle of attack sensor 40. The various parts of the device according to the present invention will now be described in detail with reference to the following figures.

[0025] See Figures 1 to 3 As mentioned earlier, the angle-of-attack sensor 40 measures the airflow by measuring the force and direction of the airflow on the wind vane 50, and then calculates information such as the aircraft's pitch angle. Specifically, during operation, the angle-of-attack sensor 40 itself remains stationary, while the wind vane 50, mounted on the angle-of-attack sensor 40, rotates along the outer edge of the angle-of-attack sensor 40 under the influence of the airflow. Based on the rotation speed and direction of the wind vane 50, the angle-of-attack sensor 40 can measure the airflow. Here, we can see that there is only one wind vane 50; correspondingly, the angle-of-attack sensor 40 is a single-wind vane type angle-of-attack sensor. The device according to the invention is used here for single-wind vane type angle-of-attack sensors, which are applied in fields such as civil aircraft, ships, automobiles, meteorology, and aerodynamics. In the aircraft field, single-wind vane type angle-of-attack sensors are, for example, mounted on both sides of the aircraft nose.

[0026] To test the functionality of a single-wind vane type angle-of-attack sensor 40, this invention proposes a dedicated device for its functional testing. The testing module 10 of this device is operably connected to the angle-of-attack sensor 40 and is configured to test various functions of the angle-of-attack sensor 40. For this purpose, the testing module 10 has a fixing and rotating unit 11, which reliably mounts the angle-of-attack sensor 40 and rotates the wind vane 50 mounted on the angle-of-attack sensor 40, thereby simulating the rotational motion of the wind vane 50 when propelled by airflow, thus enabling the angle-of-attack sensor to operate and perform functional testing.

[0027] Specifically, by Figure 2 and Figure 3 As can be seen, the fixing and rotating unit 11 includes a bracket 2 and a fixing member 1. During installation, the angle of attack sensor 40 is aligned with the mounting opening 42, preferably located at the center of the top surface of the bracket 2, so that the mounting base 41 of the angle of attack sensor 40 is centered against the top surface of the bracket 2, thereby using the bracket 2 to support the angle of attack sensor 40. At this time, the weather vane 50 passes through the groove opened on the top surface of the bracket 2 and extends into the interior of the bracket 2, so that the weather vane 50 is entirely located inside the bracket 2 without hindering its rotation. Then, the angle of attack sensor 40 is fixed to the bracket 2 using the fixing member 1, such as a fixing pin, screw, or claw. It should be noted that the height of the bracket 2 should be high enough so that after the angle of attack sensor 40 is installed, the weather vane 50 does not contact the top surface of the test module 10, thereby ensuring that the weather vane 50 will not scratch during its rotation, thus hindering the rotation of the weather vane 50 and causing the angle of attack sensor to malfunction.

[0028] See also Figure 2 and Figure 3 The fixing and rotating unit 11 also includes a connecting sleeve 4 fixedly connected to the weather vane 50, which engages with the drive shaft in the test module 10. Here, to provide power for the rotation of the weather vane 50, a motor, such as an electric motor, is installed inside the test module 10. The motor drives the drive shaft in the test module 10 to rotate, causing the connecting sleeve 4 to rotate, thereby causing the weather vane 50 to rotate accordingly. This allows the weather vane 50 to rotate within the bracket 2 along the outer edge of the angle of attack sensor 40, simulating the rotational motion of the weather vane 50 when propelled by airflow, thus preparing for the functional testing of the angle of attack sensor 40. Preferably, the fixing and rotating unit 11 also includes a protective cover 3 configured to protect the connecting sleeve 4 and the weather vane 50. Under the protection of the protective cover 3, the connecting sleeve 4 and the weather vane 50 are not affected by external factors during operation, especially preventing foreign objects from entering their working range and causing interference, ensuring the smooth conduct of the functional testing of the angle of attack sensor. Preferably, the protective cover 3 is transparent, so that the operation of the drive shaft, the coupling sleeve 4 and the wind vane 50 inside can be clearly observed, and any abnormalities can be detected in a timely manner.

[0029] The above describes some of the mechanical design aspects of test module 10. Special designs have also been implemented for test module 10 in terms of electrical and communication aspects. Specifically, test module 10 has a power supply unit 6, configured to power both test module 10 and angle-of-attack sensor 40. See [link / reference] Figure 4 and Figure 6 The power supply unit 6 features a modular power supply 61, which can flexibly switch and adjust the supply voltage according to different test items. During the testing of the angle-of-attack sensor 40, different test items are required, which may need different supply voltages, such as 220V, 115V, 28V, drive voltage, heating voltage, etc. Accordingly, the power supply unit 6 is equipped with various power switches, such as a main power switch 62, an internal 28V and external 28V voltage switching switch 63, a heating power switch 64, and also includes, for example, a DC+28V voltage fuse 65 and a heating voltage fuse 66, etc. Thus, the power supply unit 6 can provide the corresponding voltage for different test items, thereby meeting different test requirements.

[0030] In terms of communication, the test module 10 has an interface unit 5, configured to provide various test interfaces, control interfaces, and power interfaces. Here, the interface unit 5 includes, for example... Figure 6 The front interface panel 51 shown and as follows Figure 4 The rear interface panel 52 is shown. As can be seen, the front interface panel 51 has several front test interfaces, such as a front data test interface 53A for testing data transmission and a front power test interface 54A for testing power supply. These front test interfaces are electrically separated from each other and spatially spaced to facilitate manual single-item testing, thereby enabling single-point fault location, which is particularly important when performing single-step testing for a specific test item. The rear interface panel 52 includes a power supply interface 54B, an Ethernet control interface 55, a first rear data test interface 53B for testing data transmission, a second rear data test interface 53C, and other power interfaces.

[0031] exist Figure 2 As can be seen, the angle-of-attack sensor 40 has a power port 9 and a data port 8. The power port 9 is connected to the power supply interface 54B via power line d, allowing the angle-of-attack sensor 40 to be powered by the power supply unit 6 within the test module 10. Figure 3 As shown. Figure 3It is also shown that the data port 8 of the angle-of-attack sensor 40 is connected to the first rear data test interface 53B on the rear interface panel 52 via the first data transmission line e. That is, the first data transmission line e enters the test module 10 via the first rear data test interface 53B, undergoes necessary electrical processing such as grounding and shielding within the test module 10, and then exits from the second rear data test interface 53C to become the second data transmission line b. The second data transmission line b is ultimately connected to the central control module 20 for automatic full-item testing of the transmitted data. Therefore, the first rear data test interface 53B and the second rear data test interface 53C form a rear test interface that facilitates automatic full-item testing.

[0032] It should be noted that inside the test module 10, the front power test interface 54A on the front interface panel 51 is connected to the power supply interface 54B on the rear interface panel 52, and the front data test interface 53A on the front interface panel 51 is connected to the first rear data test interface 53B on the rear interface panel 52. This means that the data signal entering the test module 10 via the first rear data test interface 53B on the rear interface panel 52 along the first data transmission line e is exactly the same as the data signal leading out via the front data test interface 53A on the front interface panel 51. The only difference is that the data signal is transmitted centrally along the first data transmission line e and the second data transmission line b, so all test data can be obtained on the rear interface panel 52 connected to the first data transmission line e and the second data transmission line b, so as to finally perform automatic full-item testing. When these test data are led to the front interface panel 51, they are distributed on the separate independent front data test interfaces 53A. Figure 6 The diagram illustrates four front data test interfaces. Therefore, these front test interfaces bypass the rear test interfaces. This means that, as part of manual individual testing, the front test interfaces can supplement and refine fault location by performing bypass testing on the interface pins of the single-flare angle-of-attack sensor 40. While automatic testing can basically determine whether the angle-of-attack sensor 40 is faulty, bypass testing allows for further localization of faults in the sensor's built-in modules and pins, thereby improving the efficiency and depth of troubleshooting. Therefore, the device of this invention can perform both automatic full-item testing of the angle-of-attack sensor 40 and individual manual testing of it.

[0033] It should also be noted that although the first data transmission line e undergoes some necessary electrical processing such as grounding and shielding inside the test module 10 after entering the test module 10 via the first post-data test interface 53B, this does not affect the data transmission. In other words, the signal transmitted via the first data transmission line e, while maintaining its original signal content and signal quality, is then continuously transmitted along the second data transmission line b to the central control module 20, so that it can be automatically tested under the control of the central control module 20.

[0034] Figure 3 It is also shown that the central control module 20 is connected to the Ethernet control interface 55 on the rear interface panel 52 via data and command control line c, for transmitting data and commands with the test module 10 and the angle of attack sensor 40, thereby controlling them, such as controlling the motor in the test module 10. In addition, the central control module 20 is also connected to the test module 10 via power control line a to control the power supply to the test module 10, such as switching on and off the voltage, and adjusting it.

[0035] It can be seen that, as Figure 3 As shown, the central control module 20 is connected to the test module 10 via power control line a and data and command control line c, thereby controlling the operation of the test module 10. Furthermore, the central control module 20 is also connected to the angle-of-attack sensor 40 via a second data transmission line b, and then via a first data transmission line e, thereby controlling the operation of the angle-of-attack sensor 40. Specifically, to control the angle-of-attack sensor 40, the data acquisition module 70 includes a communication unit 30. This communication unit 30 can connect and communicate with the central control module 20, and also connect and communicate with the angle-of-attack sensor 40 via the second data transmission line b, and then via the first data transmission line e. The central control module 20 can be, for example, an industrial computer, which can be housed in the chassis 21. The communication unit 30 can also be housed in the chassis 21, for example, to facilitate connection and communication between the central control module 20 and the communication unit 30. The central control module 20 is preferably retractable, meaning it can be pulled out of the chassis 21 when in use and pushed back into the chassis 21 when not in use. The central control module 20 preferably has a display screen to facilitate observation of the control process and display of control results.

[0036] In one embodiment of the present invention, the communication unit 30 includes a discrete data transmission unit 31 and an ARINC429 bus data transmission unit 32. The discrete data transmission unit 31 is mainly used to transmit discrete signals between the angle-of-attack sensor 40 and the central control module 20. The discrete signals can characterize the current test status. The ARINC (Aeronautical Radio Inc.) 429 bus protocol is one of the most commonly used protocols for exchanging information between avionics equipment and systems, and most data on the aircraft avionics bus is transmitted using this protocol. Through the ARINC429 bus data transmission unit 32, during the single-wind-marker angle-of-attack sensor test, ARINC429 bus data communication is established between the angle-of-attack sensor 40 and the central control module 20. This enables, on the one hand, the simulation of the aircraft's air and ground environment, mainly including simulating the atmospheric environment, simulating inertial navigation conditions, and transmitting bus signals from the flap and slat electronic control unit, the nose symmetry position sensor, etc. On the other hand, it enables functions such as automatic ignition, push-button stall warning, and aircraft angle-of-attack calculation. Furthermore, the working state switching of the angle of attack sensor 40 can be realized through the coordinated action of the discrete data transmission unit 31 and the ARINC429 bus data transmission unit 32.

[0037] In one embodiment of the present invention, the data acquisition module 70 further includes a resistance measuring unit 60 configured to measure the resistance value of the built-in circuit of the angle-of-attack sensor 40. Here, the resistance measuring unit 60 can be, for example, a digital multimeter, a ohmmeter, etc. The weather vane 50 is prone to icing and frosting in cold conditions, affecting its normal operation, which manifests as a change in the resistance value of the built-in circuit of the angle-of-attack sensor 40. To defrost and de-ice the weather vane 50, it is necessary to heat the weather vane 50 using its built-in resistance wire, for example, using 115V AC power. Therefore, the functional test of the angle-of-attack sensor 40 needs to test whether heating failure will occur. In this invention, heating failure can be indicated by the relevant status bit in the ARINC429 bus data. In conjunction with the status bit indicating heating failure in the ARINC429 bus data, by measuring the resistance value of the built-in circuit of the angle-of-attack sensor 40 using the resistance measuring unit 60, the functional test of the angle-of-attack sensor 40 regarding weather vane heating failure can be completed collaboratively.

[0038] In one embodiment of the invention, a calculation and analysis unit 7 (e.g., a failure protection computer) integrated within the angle-of-attack sensor 40 calculates and analyzes data from the angle-of-attack sensor 40 and the central control module 20. Information such as the angle of attack and airflow direction measured by the angle-of-attack sensor 40, along with some information about its own operating status, is transmitted to the calculation and analysis unit 7. Based on the received information, the calculation and analysis unit 7 uses appropriate algorithms to obtain various signals in corresponding forms. These signals are transmitted to the test module 10 and the central control module 20 for various corresponding tests. On the other hand, data from the central control module 20 is transmitted to the calculation and analysis unit 7, and after calculation and analysis by the calculation and analysis unit 7, it is transmitted back to the angle-of-attack sensor 40. In this way, by utilizing the calculation and analysis function of the calculation and analysis unit 7, functions such as stall alarm and protection, stall push rod, system failure, wind vane heating failure, and automatic ignition are verified.

[0039] The following example, the driver start-up test, illustrates the process of testing a single-wind vane angle-of-attack sensor 40 using the equipment according to the present invention. The driver start-up test determines whether the data input required for the calculation and analysis units integrated within the angle-of-attack sensor 40, such as the fail-safe computer, is valid, and whether the pushrod bus operation is appropriate. This test can satisfy the functional testing requirements for the angle-of-attack sensor, including system failure, wind vane heating failure, and stall alarm.

[0040] First, log in to the test software system on the central control module 20, such as an industrial computer. After completing the pre-test preparations (including connecting various cables, setting up the switches on the interface panel, and connecting the corresponding power supply), access the test system software interface on the central control module 20. Here, operators log in to the test software system with different identities based on their job functions, thus obtaining corresponding operating permissions. The account passwords of authorized operators are managed centrally by the administrator account. After logging into the automatic test software system for the single-wind vane angle-of-attack sensor, operators can conduct tests on the corresponding test items according to work needs.

[0041] Then, the driver start-up test is performed. A one-click automatic full-item test of the single-wind vane angle-of-attack sensor 40 can be performed on the central control module 20, such as an industrial computer, through human-machine interaction. This means that all pre-set test items are tested at once. According to the present invention, single-step tests can also be performed for specific test items as needed. During the single-step test of the driver start-up test, the test software system first completes the default configuration of the angle-of-attack sensor 40 (including discrete signals, power signals, bus signals, etc.), and then determines states such as wind vane heating failure, automatic ignition device failure, and stall alarm. The entire test process is performed, for example, twice. If, after two tests, the angle-of-attack sensor 40 has no related functional faults, the relevant fault status indicator lights will all be off, and the test software system will automatically record the data of the entire test process.

[0042] Subsequently, the angle of attack sensor 40 is subjected to functional fault location. For suspected faults during the driver start-up test, if they cannot be identified and determined at once, the test results of the automatic test can be combined with the test results of the automatic test. On the front interface panel 51 of the test module 10, for example through the front test interface 53A, peripheral resources such as digital multimeters and oscilloscopes can be used to perform single-step tests to check for faults one by one, thereby completing the further location analysis of suspected functional faults of the angle of attack sensor 40.

[0043] Finally, the test conclusions are edited. After completing automatic full-function tests and possible manual single-function tests on the single-wind vane angle-of-attack sensor 40, electronic test results can be generated as needed. Operators can supplement relevant information on the test conclusions based on the test results generated by the equipment. After confirming that there are no errors, a formal electronic test report is generated and stored in the background database of the test software system for future use.

[0044] Some embodiments of this application have been described for illustrative purposes, but this application is not limited to these embodiments. Many modifications and variations will also arise in those skilled in the art. Therefore, these embodiments were selected and described to better illustrate the principles and practical applications of this application and to enable those skilled in the art to understand its contents; that is, all modifications and variations made without departing from the spirit of this application will fall within the protection scope of this application as defined by the appended claims.
