In addition, the features described for some examples can be combined into other examples.
[0019] Please refer to Figure 1 , Figure 1 which shows the overall flowchart of a thrust and pull force testing method for a thruster provided by an embodiment of the present application.
[0020] As Figure 1 shown, the thrust and pull force testing method for the thruster can at least include the following steps: Step 101: Determine the testing method based on button operations and obtain the testing parameters corresponding to the testing method.
[0021] In the embodiments of the present application, the method for testing the thrust and pull force of the thruster can be but is not limited to being applied to a programmable logic controller (PLC). The programmable logic controller is connected to the thruster through a drive unit, and the drive unit can at least include a motor driver for controlling the rotation speed of the thruster and a stepping motor for controlling the rotation of the handle. During the process of testing the thrust and pull force of the thruster, the programmable logic controller determines the test method through button operations, obtains the corresponding test parameters, and then sends the test parameters to the drive unit to control the thruster to reach a stable state corresponding to the test parameters. When it is detected that the thruster is in a stable state, the current pressure value of the pressure sensor is collected, realizing the efficient and accurate measurement of the thrust and pull force of the thruster.
[0022] Specifically, during the process of testing the thrust and pull force of the thruster, the test objective can be determined first, that is, first clarify the function or page to be tested, especially the operations related to buttons. This includes the page or module where the button is located, and the specific function to be executed after the button is triggered.
[0023] Furthermore, the button operations can be analyzed, that is, to understand in detail the type of the button (such as command button, icon button, picture button, etc.), the triggering method (such as click, hover, etc.), and the expected effect. This helps to determine the appropriate test method and test parameters.
[0024] After that, the test method can be selected, that is, according to the characteristics and requirements of the button operations, select the appropriate test method, such as testing under different rotation speeds, testing under different powers, etc.
[0025] Then, according to the test method and the specific requirements of the button operations, the corresponding test parameters can be determined. These parameters may include input values, expected results, test environment configurations, etc.
[0026] At the same time, detailed test cases can also be written based on the test method and test parameters. The test cases should clearly describe the test steps, expected results, and actual results for comparison and analysis after the test is executed.
[0027] As an option in the embodiments of the present application, determining the test method based on button operations includes: Displaying test method options through the user interface; wherein, the test method options include at least one of rotation speed test, power test, and gear test; Determining the corresponding test method based on the button operations selected by the user.
[0028] Specifically, an area can be designed in the user interface to display selectable test method options. The test method options include at least one of rotational speed test, power test, and gear test, and can also include more options as needed. A clickable button is set beside or below each test method option for the user to make a selection. When the user interface is loaded, all available test method options and their corresponding buttons are displayed, and ensure that the label of each button is clear and can accurately reflect the corresponding test method.
[0029] Next, the user browses the test method options and clicks the corresponding button according to the test requirements. The system should be able to capture the user's click event and identify the selected test method. Based on the button clicked by the user, the system determines the corresponding test method, and then, according to the determined test method, further loads the test parameters, test steps, or test interface related to this test method.
[0030] After determining the test method, the user can be guided to perform the test according to the preset test steps. During the test, information such as test data, test results, or test progress can be displayed in real time. After the test is completed, the test results can be processed and analyzed, and a test report can be generated according to the test results, test suggestions can be provided, or other subsequent operations can be performed.
[0031] Step 102: Send the test parameters to the drive unit and control the thruster to be in a stable state corresponding to the test parameters through the drive unit.
[0032] Specifically, after obtaining the test parameters, these parameters can be sent to the drive unit through reliable communication means. The drive unit includes a motor driver and a stepper motor. The drive unit receives and verifies the test parameters, and then converts the parameters into specific control instructions for the thruster to implement control and ensure that the thruster operates according to the preset parameters.
[0033] Furthermore, sensors can be used to monitor the real-time state of the thruster and analyze the state data to evaluate whether the thruster reaches a stable state, so that the control instructions can be adjusted according to the analysis results to achieve stable control.
[0034] As another option in the embodiment of the present application, the test parameters include the maximum rotational speed corresponding to the rotational speed test type; Sending the test parameters to the drive unit and controlling the thruster to be in a stable state corresponding to the test parameters includes: Sending the maximum rotational speed to the motor driver, and the motor driver increases the rotational speed of the thruster according to the maximum rotational speed and the preset stepped rotational speeds to control the thruster to be in a stable state corresponding to the maximum rotational speed; Calculate the rotational speed fluctuation value of the thruster based on the preset time interval; When it is detected that the rotational speed fluctuation value is within a preset first threshold range, it is determined that the thruster is in a stable state.
[0035] Specifically, taking the test parameters including the maximum rotational speed corresponding to the rotational speed test type as an example, during the process of sending the test parameters to the drive unit and controlling the thruster to be in a stable state corresponding to the test parameters through the drive unit, the maximum rotational speed and a series of preset stepped rotational speeds can be determined first, and these rotational speed parameters are sent to the motor driver. After receiving the parameters, the motor driver starts to control the rotational speed of the thruster to gradually increase until the maximum rotational speed is reached.
[0036] It can be understood that the motor driver gradually increases the rotational speed of the thruster so that it gradually rises according to the preset stepped rotational speed values. After reaching the maximum rotational speed, the motor driver continues to fine-tune the thruster to ensure that the thruster can operate stably at this rotational speed.
[0037] Then, the rotational speed of the thruster can be monitored in real time by using a sensor, and further, based on a preset time interval, the rotational speed fluctuation value of the thruster within this time period can be calculated. At the same time, a first threshold range can be preset to judge the acceptable degree of rotational speed fluctuation. When the monitored rotational speed fluctuation value is within the preset first threshold range, it is considered that the thruster has reached a stable state.
[0038] Here, taking 2000 rpm as the maximum rotational speed and 100 rpm as the preset stepped rotational speed as an example. Click to start running. After setting the forward and reverse rotation, maximum rotational speed, and stepped rotational speed, the PLC will control the GCU (i.e., the motor driver) to run from 0 to 100 rpm. When the real-time rotational speed feedback by the GCU reaches 100 rpm, the PLC records the current pressure value in real time. And if it is not greater than the maximum rotational speed at this time, the PLC will control the GCU to increase from 100 rpm to 200 rpm. If it is still not greater than the maximum rotational speed at this time, the rotational speed will continue to increase to 300 rpm, and so on, until it increases to 2000 rotational speed and then stops running.
[0039] As another alternative of the embodiment of the present application, the test parameters include the maximum power corresponding to the power test type; Sending the test parameters to the drive unit and controlling the thruster to be in a stable state corresponding to the test parameters through the drive unit includes: Sending the maximum power to the motor driver, and the motor driver increases the rotational speed of the thruster according to the maximum power and a preset stepped power to control the thruster to be in a stable state corresponding to the maximum power; Calculating the power fluctuation value of the thruster based on a preset time interval; When it is detected that the power fluctuation value is within a preset second threshold range, it is determined that the thruster is in a stable state.
[0040] Specifically, taking the maximum power corresponding to the power test type as an example among the test parameters, in the process of sending the test parameters to the drive unit and controlling the thruster to be in a stable state corresponding to the test parameters through the drive unit, the maximum power value and a series of preset stepped power values can be set first, and these power parameters are sent to the motor driver. The motor driver controls the rotational speed of the thruster to gradually increase according to the received power parameters, and then adjusts the rotational speed to gradually increase the input power of the thruster until the maximum power is reached.
[0041] Next, sensors or other monitoring means can be used to monitor the input power of the thruster in real time, so that the power fluctuation value of the thruster within this time period can be calculated based on a preset time interval. At the same time, a second threshold range can be preset to determine the acceptable degree of power fluctuation. When the monitored power fluctuation value is within the preset second threshold range, it is determined that the thruster is in a stable state.
[0042] Here, taking 3000W power as the maximum value and 500W as the stepped power as an example. Click to start running. After setting the forward and reverse rotation, maximum power, and stepped power. The PLC will control the GCU to increase the rotational speed until the power calculated by its feedback is 500W. The PLC records the current pressure value in real time. Since it is not greater than the maximum power at this time, the PLC will continue to control the GCU to increase the rotational speed until the power calculated by the feedback is 1000W. Since it is still not greater than the maximum power at this time, continue to control, and so on, until after increasing its value to 3000W, stop running.
[0043] As another option in the embodiment of the present application, the test parameters include the maximum gear rotation angle corresponding to the gear test type; Sending the test parameters to the drive unit and controlling the thruster to be in a stable state corresponding to the test parameters through the drive unit includes: Calculating the rotation angle of each gear according to the maximum gear rotation angle and the preset number of gears; Controlling the stepping motor to rotate the handle according to the rotation angle of each gear, and the motor driver controls the thruster to be in a stable state corresponding to the maximum gear rotation angle based on the rotation angle of the handle; Calculating the rotational speed fluctuation value of the thruster based on a preset time interval; When it is detected that the rotational speed fluctuation value is within the preset first threshold range, it is determined that the thruster is in a stable state.
[0044] Specifically, taking the test parameter including the maximum gear rotation angle corresponding to the gear test type as an example, in the process of sending the test parameter to the drive unit and controlling the thruster to be in a stable state corresponding to the test parameter through the drive unit, the maximum gear rotation angle and the preset number of gears can be determined first. Then, based on the maximum gear rotation angle and the number of gears, the rotation angle corresponding to each gear can be calculated. This step ensures that the stepper motor can accurately rotate to the predetermined position at each gear.
[0045] Next, the programmable logic controller can control the stepper motor to rotate the handle according to the rotation angle of each gear. For example, but not limited to, controlling the rotation angle of the stepper motor by sending the number of pulses. After the handle rotates, the motor driver can control the thruster to gradually be in a stable state corresponding to the maximum gear rotation angle according to the rotation angle of the handle. It can be understood that the rotation angle of the stepper motor is proportional to the number of pulses sent by the programmable logic controller. Therefore, the rotation angle of the stepper motor can be accurately controlled by adjusting the number of pulses.
[0046] After that, during the rotation of the thruster, the sensor can be used to monitor its rotational speed in real time. Thus, based on the preset time interval, the rotational speed fluctuation value of the thruster within this time period can be calculated to evaluate the operating stability of the thruster. At the same time, a first threshold range can be preset to judge the acceptable degree of the rotational speed fluctuation. When the monitored rotational speed fluctuation value is within the preset first threshold range, it is determined that the thruster is in a stable state to ensure that the thruster can operate stably at the maximum gear rotation angle.
[0047] Here, taking 150° as the maximum rotation angle and 10 gears as an example. Click to start running. After forward and reverse rotation, maximum rotation angle, and gear setting. The PLC will control the stepper motor to rotate 15°. After the rotation is completed, it will judge according to the rotational speed feedback by the GCU. When the rotational speed fluctuation is not greater than ±5 rpm, record the current pushing and pulling force, and continue to rotate 15° until it rotates 10 times to reach the maximum rotation angle.
[0048] As another option of the embodiment of the present application, calculating the rotation angle of each gear according to the maximum gear rotation angle and the preset number of gears includes: Dividing the maximum gear rotation angle by the number of gears to obtain the rotation angle of each gear; where the number of gears is an integer and greater than or equal to 2.
[0049] Specifically, in the process of calculating the rotation angle of each gear according to the maximum gear rotation angle and the preset number of gears, the rotation angle of the thruster at the maximum gear can be determined first. And set an integer as the number of gears, and this value should be greater than or equal to 2 to ensure that there are at least two gears for adjustment.
[0050] Next, divide the maximum gear rotation angle by the number of gears. The result is the rotation angle for each gear, ensuring that the rotation angles between each gear are uniform. Therefore, the specific rotation angle value for each gear can be calculated based on the set parameters.
[0051] Step 103: When it is detected that the thruster is in a stable state, collect the current pressure value of the pressure sensor.
[0052] Specifically, when it is determined that the thruster is in a stable state according to the preset determination conditions (such as but not limited to the rotational speed fluctuation value being within the preset first threshold range), the data collection function of the pressure sensor can be immediately activated. Among them, the pressure sensor should be connected to the key parts of the thruster or related systems to monitor the pressure changes at that place in real time.
[0053] Furthermore, the current pressure value can be read from the pressure sensor. This is usually achieved through the communication interface between the sensor and the data collection system (such as analog signal output, digital signal communication, etc.). At the same time, the collected current pressure value can be stored in the data recording system to evaluate the performance of the thruster in a stable state.
[0054] As another alternative in the embodiments of the present application, after collecting the current pressure value of the pressure sensor, it further includes: Compare the current pressure value with the preset pressure threshold; If the current pressure value is greater than or equal to the preset pressure threshold, generate a qualified signal; If the current pressure value is less than the preset pressure threshold, generate an unqualified signal.
[0055] Specifically, after collecting the current pressure value of the pressure sensor, the obtained current pressure value can also be compared with the preset pressure threshold. Among them, the one or more preset pressure thresholds are usually determined based on factors such as the design specifications of the thruster, safe operating conditions, or historical data.
[0056] If the current pressure value is greater than or equal to any one of the preset pressure thresholds, a qualified signal can be generated, which also indicates that the thruster is in a normal state.
[0057] At the same time, if the current pressure value is less than any preset pressure threshold, it indicates that the thruster may be abnormal in the current state. Of course, an alarm signal can be generated but is not limited to this.
[0058] It can be understood that for the generated alarm signal, detailed fault troubleshooting and analysis can also be carried out to determine the specific cause of the pressure exceeding the threshold value. Furthermore, corresponding repair measures can be taken according to the troubleshooting results, such as adjusting the thruster settings, replacing damaged components, etc. After the repair is completed, the test or operation can be restarted, and the pressure value can be continuously monitored to ensure the stable operation of the system.
