Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of airborne avionics testing, in particular, to a head-up display combination instrument durability test system and method. BACKGROUND

[0002] The core components of the head-up display combination instrument can include a combination mirror, an unlocking handle and a rotating arm. The combination mirror has three states: an unfolded state (in use), a folded state (not in use) and a separated state (leaving the working state due to unexpected impact). Each state corresponds to a position, specifically, the unfolded state corresponds to an unfolded position, the folded state corresponds to a folded position, and the separated state corresponds to a separated position. The position of the combination mirror can be switched by rotating the rotating arm to achieve the switching of the state of the combination mirror. The unlocking handle is locked or unlocked by pulling it in different directions, specifically, the unlocking handle is pulled to the side of the operator to be locked, and is pulled to the side of the windshield of the aircraft to be unlocked.

[0003] When the head-up display is not used, the unlocking handle needs to be pulled to the unlocked state first, then the rotating arm is pulled to the pilot direction to switch the combination mirror to the folded position, and then to the folded state, and finally the unlocking handle is pulled back to the locked state to stably fix the combination mirror in the folded state. When the head-up display is used, the unlocking handle needs to be pulled to the unlocked state first, then the rotating arm is pulled to the windshield direction to switch the combination mirror to the unfolded position, and then to the unfolded state, and then the unlocking handle is pulled back to the locked state to stably fix the combination mirror in the unfolded state. When the combination instrument is subjected to an unexpected impact reaching a preset threshold, the combination mirror can automatically pop open and switch to the separated position, and then to the separated state, regardless of whether the unlocking handle is currently in the locked or unlocked state, to avoid the collision between the pilot's head and the combination mirror. If the combination mirror needs to be restored from the separated position (i.e. the separated state) to the unfolded position (i.e. the unfolded state), the rotating arm can be directly pulled in the reverse direction without the need to operate the unlocking handle.

[0004] According to the reliability requirements, the structure with the steering function (such as rotating arm driving and locking device switching) needs to be verified for performance stability after long-term use through durability testing. According to the testing requirements, the durability test needs to be performed for tens of thousands of times, and therefore, an automatic durability test system is urgently needed. SUMMARY

[0021] Figure 1 A schematic diagram of a head-up display (HUD) combination device durability testing system provided in this application embodiment is shown below. Figure 1 As shown, the system may include: a mechanical actuation module 110, a main control and drive module 120, and a signal acquisition module 130. Wherein: The combination instrument 100 is installed on the mechanical actuation module 110.

[0022] The master control and driving module 120 can generate a control signal according to the control parameters of the mechanical execution module 110 corresponding to the preset durability test of the combination instrument 100. The mechanical execution module 110 can perform the preset durability test on the combination instrument 100 in response to the control signal.

[0023] For example, the master control and driving module 120 can be implemented by a PLC and a motor driver. The master control and driving module 120 is configured to generate a control signal according to the control parameters of the mechanical execution module 110 corresponding to the preset durability test of the combination instrument 100, and drive the mechanical execution module 110 to perform the preset durability test on the combination instrument 100 through the control signal.

[0024] The signal acquisition module 130 can collect the test state information of the mechanical execution module 110 and the position information of the combination instrument 100 during the preset durability test on the combination instrument 100, and send the test state information of the mechanical execution module 110 and the position information of the combination instrument 100 to the master control and driving module 120.

[0025] The signal acquisition module 130 can be implemented by a clamp pressure sensor and a photoelectric encoder to collect the test state information of the mechanical execution module 110, and can be implemented by a discrete quantity board card to collect the position information of the combination instrument 100.

[0026] The master control and driving module 120 can also generate a test result and / or an alarm information according to the test state information of the mechanical execution module 110, the position information of the combination instrument 100, and the test safety parameters.

[0027] For example, the test state information of the mechanical execution module 110 is compared with the corresponding information in the test safety parameters, and the position information of the combination instrument 100 is compared with the corresponding information in the test safety parameters to obtain a comparison result. The alarm information is generated according to the comparison result. For example, when there is an inconsistent comparison result, the alarm information is generated.

[0028] Obviously, the master control and driving module 120 generates a control signal according to the control parameters of the mechanical execution module 110 corresponding to the preset durability test, and the mechanical execution module 110 can perform the preset durability test on the combination instrument 100 in response to the control signal, without the need for manual triggering of the control signal or manual operation of the execution component. Compared with the traditional test method relying on manual operation, not only the manual operation steps and manual intervention are reduced, the risk of test deviation caused by manual operation errors is reduced, the consistency and stability of the test are ensured, but also the labor cost is saved, and long-time continuous and uninterrupted test can be realized, which adapts to the long-period requirement of combination instrument durability test, improves the test efficiency, and realizes automatic durability test.

[0029] In the process of presetting the durability test of the combination instrument 100, the signal acquisition module 130 acquires the test state information of the mechanical execution module 110 and the position information of the combination instrument 100, and sends the test state information of the mechanical execution module 110 and the position information of the combination instrument 100 to the main control and driving module 120, so that the main control and driving module 120 generates a test result and / or an alarm information according to the test state information of the mechanical execution module 110, the position information of the combination instrument 100 and the test safety parameter, so as to prompt through the alarm information, ensure the safety in the test process, and realize the automatic generation of the test result. Compared with the traditional manual recording of test data, the manual recording error can be reduced, and the accuracy of the test result is ensured. Moreover, the signal acquisition module can also realize real-time monitoring by acquiring the test state information of the mechanical execution module and the position information of the combination instrument during the test.

[0030] The main control and driving module 120 can generate a control signal according to the control parameter of the mechanical execution module 110 corresponding to the preset durability test of the combination instrument 100, so that the mechanical execution module 110 responds to the control signal to perform the preset durability test on the combination instrument 100. That is, based on the different preset durability test requirements of the combination instrument 100, the control parameter can be flexibly adjusted, without the need to make large improvements to the system hardware structure, thereby improving the adaptation range of the durability test of the system, and further improving the versatility and applicability of the system, and reducing the test cost.

[0031] In some embodiments, as shown in Figure 2 The system can further include a human-computer interaction module 140.

[0032] The human-computer interaction module 140 can provide an interactive interface to the user, and obtain the control parameter and the test safety parameter of the mechanical execution module 110 corresponding to the preset durability test set by the user in response to the operation on the interactive interface, and send the control parameter and the test safety parameter of the mechanical execution module 110 corresponding to the preset durability test to the main control and driving module 120, and display the control parameter and the test safety parameter of the mechanical execution module 110 corresponding to the preset durability test, and display the test state information of the mechanical execution module 110, the position information of the combination instrument 100, the test result and / or the alarm information.

[0033] For example, the human-computer interaction module 140 can be realized through a touch screen.

[0034] In some embodiments, the combination instrument 100 can include a combination mirror, an unlocking handle and a rotating arm. The combination mirror is provided with a plurality of states. The plurality of states include an unfolded state (in use), a folded state (not in use) and a separated state.

[0035] The three states correspond to the three positions one by one. Specifically, the unfolded state corresponds to the unfolded position, the folded state corresponds to the folded position, and the separated state corresponds to the separated position.

[0036] The preset durability test can refer to switching back and forth between at least two states in a plurality of states by operating the unlocking handle and the swing arm control to control the combined mirror. For example, operating the unlocking handle and the swing arm control completes a certain angle of rotation and then completes switching of different positions of the combined mirror and then completes switching of different states.

[0037] Based on this, the mechanical execution module 110 can include a bracket, a moving positioning unit, and a rotating clamping unit. The bracket is provided with a mounting interface of a mounting tool of the combined instrument 100, and the combined instrument 100 is mounted on the bracket through the mounting tool and the mounting interface. The bracket can be realized by a cast iron base.

[0038] The moving positioning unit is installed on the bracket and connected with the rotating clamping unit.

[0039] The moving positioning unit drives the rotating clamping unit to move and rotate in a three-dimensional space (i.e., the moving positioning unit can drive the rotating clamping unit to complete movement and rotation in three directions of horizontal, vertical, and perpendicular), and controls the rotating clamping unit to perform the centering operation with the unlocking handle and the swing arm. The centering operation refers to controlling the rotating clamping unit to hold the center position of the unlocking handle and the center position of the swing arm when the rotating clamping unit holds the unlocking handle and the swing arm, so as to realize stable holding and connection, thereby ensuring the stability of the test.

[0040] For example, the moving positioning unit can be realized by a stepping motor and a reducer, and cooperate with a grating ruler to realize closed-loop control of three-dimensional movement. The moving positioning unit can also drive the rotating clamping unit to switch back and forth between the centering positions of the unlocking handle and the swing arm.

[0041] The mechanical execution module 110 can be specifically used to respond to the control signal by controlling the moving positioning unit to drive the rotating clamping unit to operate the unlocking handle and the swing arm, so as to switch the state of the combined mirror between any two states in a plurality of states, so as to perform the preset durability test.

[0042] That is, the mechanical execution module 110 can be specifically used to respond to the control signal by controlling the moving positioning unit to drive the rotating clamping unit to operate the unlocking handle and the swing arm, so as to switch the position of the combined mirror between any two positions in a plurality of positions, and then realize switching of the combined mirror between any two states in a plurality of states, thereby realizing the preset durability test.

[0043] Exemplarily, the control parameters of the mechanical execution module 110 include, but are not limited to, the moving stroke and the moving speed of the moving positioning unit, the moving stroke, the moving speed, the rotating direction, the rotating angle of the rotating clamping unit, the action interval time, the action, and the total cycle number, etc. The total cycle number can be understood as the number of times that the combination mirror switches between different states.

[0044] The test safety parameters include, but are not limited to, the moving stroke threshold of the moving positioning unit, the moving speed threshold of the moving positioning unit, the rotating angle threshold of the rotating clamping unit, the clamping force threshold of the rotating clamping unit, the reference position corresponding to each state of the plurality of states of the combination mirror, etc.

[0045] It should be noted that when the combination mirror is located at a reference position, it is indicated that the combination mirror is in the state corresponding to the reference position. In this way, in the subsequent test process, whether the position switching (i.e., the state switching) has a fault can be determined by collecting the position of the combination mirror and comparing it with the reference position.

[0046] Based on this, the test state information of the mechanical execution module 110 includes, but is not limited to, the moving stroke of the moving positioning unit, the moving speed of the moving positioning unit, the rotating angle of the rotating clamping unit, the clamping force threshold of the rotating clamping unit, etc. The position information of the combination instrument 100 can include the position of the combination mirror when it switches to each state in the test process.

[0047] Obviously, by setting the test safety parameters, the test state information of the mechanical execution module 110 collected in the test process can be compared with the corresponding data in the test safety parameters, and the position information of the combination instrument 100 collected in the test process can be compared with the corresponding data in the test safety parameters, to obtain a comparison result. When there is inconsistent data in the comparison result, it is determined that there is a fault or an abnormality, and an alarm information is generated to notify the staff to troubleshoot the fault or the abnormality.

[0048] Moreover, the test result can also be generated according to the test state information of the mechanical execution module 110, the position information of the combination instrument 100, and the test safety parameters.

[0049] In some embodiments, the rotating clamping unit can adapt to the shape and size of the handle and the rotating arm. That is, the rotating clamping unit can adapt to the shape and size of the handle and the rotating arm and clamp the handle and the rotating arm, so as to better complete the forward and reverse rotation and movement within a range of 360°. The rotating clamping unit can adopt a servo motor and a reducer to realize the rotation within a range of 360°, and can adopt a double-claw servo clamp matched with a silica gel pad (anti-skid and surface protection) to realize the adaptive clamping of the handle and the rotating arm.

[0050] Obviously, in this way, the rotating clamping unit can be better connected with the handle and the rotating arm, and thus more stable control can be performed.

[0051] The preset durability test process is exemplarily described below by taking the operation of the unlocking handle and the rotating arm control combination mirror from the stowed position (i.e., the stowed state) to the unfolded position (i.e., the unfolded state) and from the unfolded position to the stowed position (i.e., the preset durability test) as an example.

[0052] Suppose that the unlocking handle needs to be rotated counterclockwise by 30° for unlocking and clockwise by 30° for locking, the rotating arm needs to be rotated counterclockwise by 70° for unfolding and clockwise by 70° for stowing. The positions of the rotating clamping unit of the mechanical execution module 110 and the unlocking handle in which the rotation centers are aligned in the locked and unlocked states are A1 (X1, Y1, Z1) and A2 (X2, Y2, Z2), respectively, and the positions of the rotating clamping unit of the mechanical execution module 110 and the rotating arm in which the rotation centers are aligned in the stowed and unfolded states are B1 (X3, Y3, Z3) and B2 (X4, Y4, Z4), respectively. Based on this, the execution process of the mechanical execution module 110 is as follows: Initial state: the mechanical execution module 110 is in the standby position; 1) move to position A1 (X1, Y1, Z1); 2) rotate the clamping unit to clamp the unlocking handle by 30° counterclockwise; 3) delay for 1 s and move to B1 (X3, Y3, Z3); 4) rotate the clamping unit to clamp the rotating arm by 70° counterclockwise; 5) delay for 1 s and return to position A2 (X2, Y2, Z2); 6) rotate the clamping unit to clamp the unlocking handle by 30° clockwise; 7) rotate the clamping unit by 30° counterclockwise; 8) delay for 1 s and move to B2 (X4, Y4, Z4); 9) rotate the clamping unit to clamp the rotating arm by 70° clockwise; 10) delay for 1 s and move to position A2 (X2, Y2, Z2); 11) rotate the clamping unit to clamp the unlocking handle by 30° clockwise; 12) count +1 and return to the standby position.

[0053] During the test process, the main control and driving module 120 can determine the durability test result according to the test state information of the mechanical execution module 110 and the position information of the combination mirror 100 collected by the signal collection module 130. When any of the following conditions occurs in a certain cycle: 1) the rotation angle and the clamping force exceed the corresponding threshold value; 2) the collected position of the combination mirror 100 is inconsistent with the reference position of the combination mirror 100.

[0054] The main control and driving module 120 should immediately stop and generate corresponding alarm information, and record the current cycle number.

[0055] In some embodiments, the determination of the durability test cycle number can be as follows: Taking the average failure interval time of the combination instrument 100 as 20000 flight hours for example, assuming that the average flight time of each flight landing cycle is 2 flight hours, and the pilot uses the head-up display to assist flight during take-off and landing in each flight landing cycle, the average operation number of the combination instrument 100 is 2 times (the following operation is repeated twice in each flight landing cycle: adjusting the combination mirror from the stowed position to the deployed position, and then from the deployed position to the stowed position.) The durability test cycle number is multiplied by a safety factor of 1.5 based on the design expected flight cycle number, so the durability test cycle number for normal operation of the combination instrument should be set as: 20000 ÷ 2 × 2 × 1.5 = 30000 times.

[0056] As shown in Figure 3 The embodiment of the present application also provides a head-up display combination instrument durability test method, applied to the head-up display combination instrument durability test system, which can include the following steps: 301. The combination instrument 100 is installed on the support of the mechanical execution module 110 through the installation tool.

[0057] 302. The positions of the moving positioning unit and the rotating clamping unit in the mechanical execution module 110 are adjusted so that the rotating clamping unit is respectively aligned with the unlocking handle and the center of the rotating arm in the combination instrument 100, and the positions of the moving positioning unit and the rotating clamping unit, the rotating direction and the rotating angle of the rotating clamping unit when the center is aligned are recorded.

[0058] 303. According to the preset durability test, the positions of the moving positioning unit and the rotating clamping unit when the center is aligned, the rotating direction and the rotating angle of the rotating clamping unit, the control parameters and the test safety parameters of the mechanical execution module 110 corresponding to the preset durability test are set.

[0059] 304. According to the control parameters and the test safety parameters of the mechanical execution module 110 corresponding to the preset durability test, the moving positioning unit and the rotating clamping unit in the mechanical execution module 110 are driven by the main control and driving module 120 to perform the preset durability test on the combination instrument 100.

[0060] 305. The test state information of the mechanical execution module 110 and the position information of the combination instrument 100 are collected by the information collection module 130 during the preset durability test.

[0061] 306. The master control and driving module 120 generates test results and / or alarm information according to the test state information of the mechanical execution module 110, the position information of the combination instrument 100 and the test safety parameters.

[0062] Although the present application has been disclosed with reference to the above embodiments, the scope of the present application is not limited to the above. Various changes and modifications can be made thereto without departing from the spirit and scope of the present application, and such changes and modifications are intended to fall within the scope of the present application.
