[0039] Pedal assembly test module: The drive motor control module (using the DQ356M motor driver) is responsible for controlling the pedal assembly's drive motor to adjust the pedal position; the pedal position feedback sensor (also using the CX-B1-100 model) provides accurate position feedback; the control switch module (a 4-pin, 2-speed switch) is used to select the test mode or manually control the motor start and stop, increasing operational flexibility.

[0041] Specifically, it is used to test and inspect the pitch adjustment function and performance of the control column assembly and pedal assembly of a certain type of aircraft to determine whether the pitch adjustment function and performance of the control column and pedals meet the requirements, such as Figure 2 The device has the following functions:

[0042] A. Adjusting the distance of the joystick:

[0043] 1) Measure the limit voltage before the control stick;

[0044] 2) Measure the limit voltage behind the control stick;

[0045] 3) Test the automatic forward and backward movement of the control stick;

[0046] 4) Test the manual forward and backward movement of the control stick;

[0047] 5) Measure the output voltage of the Q / KZH-881 automatic pedal adjustment driver;

[0048] 6) Perform on / off test on the pedal adjustment switch.

[0049] B. Pedal adjustment:

[0050] 1) Measure the zero-position output voltage of the pedal position sensor;

[0051] 2) Measure the pedal position sensor's maximum stroke output voltage;

[0052] 3) The measuring pedal automatically moves forward and backward;

[0053] 4) Measure the manual forward and backward movement of the pedal.

[0054] The tester is the core of the entire test control, and the control protection board is the control core of the tester. Its logic principle block diagram is as follows Figure 3 As shown:

[0055] The tester provides 28VDC power to the control column actuator and 15VDC to the position feedback sensor. The sensor outputs from the pedal and control column assemblies are connected to the tester panel for external testing. The tester operates in two modes: tester mode for single-unit testing and system mode for combined testing of the control column and pedal assemblies. Select the appropriate operating mode based on your test needs.

[0056] D.2.2.2.1 Working principle of the tester test mode

[0057] The test mode of the tester is suitable for separate testing of the steering column or pedal assembly. If only the pedal or steering column assembly is tested, this mode can be used.

[0058] 1) Pedal assembly test:

[0059] During the test, the operator sends control instructions to the control protection board through the control switch on the panel. The control protection board is a digital control circuit with a single-chip microcomputer as the core. The control protection board sends corresponding control signals to control the output of the driver board inside the tester according to the control instructions of the operator. The automatic and manual outputs of the driver board are sent to the drive motor of the distance adjustment mechanism through a cable, driving the pedal device to move back and forth, thereby completing the manual and automatic distance adjustment test of the pedal.

[0060] At the same time, the output of the driver board and the output signal of the pedal position feedback sensor are led to the detection hole of the tester panel, which is convenient for using external instruments to detect the output voltage of the driver and position sensor.

[0061] 2) Steering column test:

[0062] The test of the control column assembly is aimed at testing the control column adjustment drive and the control column pitch adjustment mechanism.

[0063] 1) Automatic part test

[0064] The operator uses the control switches on the tester panel to send commands to the control and protection board for the automatic forward and reverse movement of the stick and pedals. The control and protection board then issues corresponding control signals to control the output of the stick adjustment actuator. The automatic output of the adjustment actuator's stick is directly connected to the stick pitch adjustment mechanism, allowing for intuitive inspection of the fore-and-aft movement of the stick assembly. The automatic output of the adjustment actuator's pedals is connected to the tester panel, and voltage can be measured with an external multimeter to verify correctness.

[0065] During the automatic forward and backward test of the joystick, the control protection board will continuously monitor the output of the joystick position feedback sensor and perform protection when necessary, stopping the automatic forward and backward control instructions to the joystick adjustment driver to ensure that the joystick is always in a safe state when it moves forward or backward automatically.

[0066] 2) Manual part test

[0067] Operate the manual position adjustment switch on the steering column assembly to check the forward and backward movement of the steering column assembly. This is to confirm whether the manual adjustment function of the steering column is normal.

[0068] The output of the manual pedal position adjustment switch on the operating lever assembly is connected to the tester panel and can be verified by measuring the voltage with an external multimeter to see if it is correct.

[0069] D.2.2.2.2 Working principle of system test mode

[0070] The system test mode is suitable for joint testing of the steering column assembly and the pedal assembly. This allows the entire PCU to be tested quickly, improving test efficiency.

[0071] During the joint test, the control column assembly and the pedal assembly are connected at the same time to complete the manual and automatic pitch adjustment tests.

[0072] The test principle is basically the same as the test mode of the tester. The difference is that during automatic and manual tests, the movement of the pedal assembly during automatic and manual distance adjustment can be directly observed.

[0073] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields.
