Description

Technical Field

[0001] This application relates to the technical field of selection verification, and particularly to a method and system for verifying the selection of a device under test. Background Art

[0002] The matching selection of a motor and a speed reducer is a key link in the design of a mechanical transmission system, directly affecting the operating efficiency, stability, and lifespan of the device. A reasonable matching of a motor and a speed reducer can not only improve the performance of the transmission system but also optimize energy consumption and reduce the failure rate. In the traditional matching selection process, theoretical calculations, empirical estimations, or single-unit tests are usually used for verification. However, limited by the complexity of the actual working conditions, single-unit tests are difficult to comprehensively evaluate the matching performance of a motor and a speed reducer under different loads.

[0003] Especially for intelligent cleaning devices, etc., the development cycle is short, and the need for rapid verification and efficient selection is particularly urgent. Due to the low test efficiency and lagging feedback of traditional methods, it is difficult to complete a comprehensive performance evaluation and optimization within a limited time, thus affecting the product's time to market and market competitiveness.

[0004] Therefore, there is an urgent need to provide a method and system for verifying the selection of a device under test to improve the accuracy and reliability of the matching selection. Summary of the Invention

[0005] To overcome the above deficiencies, this application provides a method and system for verifying the selection of a device under test.

[0006] The objectives of this application are achieved by the following technical solutions:

[0007] In a first aspect, this application provides a method for verifying the selection of a device under test. The device under test includes multiple test modules to be set at different positions, and each test module includes a motor under test and a speed reduction module under test connected by a shaft; the method includes:

[0008] Obtain combined test information corresponding to the test positions of each test module. The combined test information includes multiple sets of preset data, and each set of preset data includes a load test data and a test signal data;

[0009] For each test module, perform tests using its corresponding test equipment according to the combined test information, and obtain the test data when each set of preset data is used; determine whether each test module meets the preset test requirements when tested with each set of predicted data in the combined test information;

[0010] When each of the test modules meets the preset test requirements, it is considered that the device under test meets the verification requirements for the selection.

[0011] The beneficial effects of this technical solution are as follows. By simultaneously testing multiple modules to be tested and comprehensively evaluating them using multiple sets of preset data, it is possible to complete a comprehensive performance test in a relatively short period of time, improving the test efficiency and shortening the development cycle. By simulating different load and signal conditions, it is possible to comprehensively evaluate the performance of the device to be tested under various actual working conditions, ensuring the accuracy and reliability of the test results, and helping to screen out the optimal device combination. By conducting verification in the early selection stage, it is possible to reduce rework and modification due to unqualified performance in the later stage, reducing the development cost and project risk.

[0012] In summary, this technical solution provides an efficient, flexible, and comprehensive method for verifying the selection of devices to be tested, which helps to ensure the performance and reliability of the devices, optimizes the development process, and reduces costs and risks.

[0013] Preferably, when at least one module to be tested does not meet the preset test requirements, a prompt message is generated and sent to the user device, and the prompt message is used to instruct the user to replace the new device to be tested for selection verification.

[0014] The beneficial effects of this technical solution are as follows. Through an automated monitoring and prompt mechanism, it is possible to quickly identify modules to be tested that do not meet the requirements, avoiding the cumbersome process of manual inspection one by one, and improving the test efficiency; at the same time, it ensures that only devices that fully meet the requirements can pass the verification, improving the accuracy of the test results. The automated prompt reduces the need for manual monitoring, reduces the risk of misjudgment caused by human negligence, and improves the reliability of the test process. Users can receive feedback on the test results in a timely manner and respond quickly, such as replacing devices or adjusting the test strategy, shortening the overall test cycle.

[0015] In summary, this technical solution significantly improves the efficiency and accuracy of the test process by introducing an automated prompt mechanism, reduces manual intervention, provides real-time feedback, enhances the user experience, and reduces development costs and risks.

[0016] Preferably, the method for determining whether each set of predicted data in the combined test information of the module to be tested meets the preset test requirements includes:

[0017] Obtain the numerical range of each test data from the preset test requirements; when each set of test data of the module to be tested in the combined test information is within its corresponding numerical range, it is considered to meet the preset test requirements.

[0021] Multiple pairing combinations are obtained according to a one-to-one pairing principle between multiple load test information and multiple input test signal information.

[0022] The beneficial effect of this technical solution is that by pairing and combining multiple load test information and input test signal information, it is possible to simulate various working conditions that the device under test may encounter in actual applications, ensuring the comprehensiveness and accuracy of the test. By pre-defining test strategy information and generating combined test information, the test process can be systematically organized, manual intervention can be reduced, and test efficiency can be improved.

[0023] Preferably, the device to be tested is applied to an intelligent cleaning device, and includes four modules to be tested, which are respectively located at the left front, left rear, right front and right rear positions of the intelligent cleaning device.

[0024] The beneficial effect of this technical solution is that by testing four modules to be tested at the same time and using multiple sets of preset data for comprehensive evaluation, comprehensive performance testing can be completed in a shorter time, improving test efficiency and shortening the development cycle. By simulating the load and signal conditions corresponding to four different positions, the performance of the intelligent cleaning equipment under various actual working conditions can be fully evaluated, ensuring the accuracy and reliability of the test results, which helps to screen out the optimal equipment combination.

[0025] Preferably, the step of performing the test using the corresponding test equipment according to the combined test information includes:

[0026] According to the load test data in the combined test information, the load parameters of the test equipment are adjusted; and according to the test signal data corresponding to the load test data, the module to be tested is controlled to perform the test.

[0027] The beneficial effect of this technical solution is that by analyzing the combined test information and adjusting the load parameters, the load conditions in actual working conditions can be accurately simulated, that is, the load parameters and control signals can be flexibly adjusted according to different test requirements to adapt to various test scenarios.

[0042] Next, in combination with the accompanying drawings and specific implementation manners, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments. The following will illustrate the implementation procedures of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific implementation procedures. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, rather than for limiting the protection scope of the present application.

[0043] The existing motor and speed reducer selection and verification methods do not consider new devices with a relatively short development cycle such as intelligent cleaning devices. Taking a motor loading performance test system disclosed in Application No. CN201010264126.1 as an example, it includes: a drive power supply, a motor under test, a coupling, a synchronous generator, a synchronous generator load, and a measurement and control unit; in the present invention, by accompanying and winding a detection winding on the stator power winding of the synchronous generator, during actual testing, only by detecting the input voltage and input current of the motor under test, the induced electromotive force and induced electromotive force frequency of the detection winding of the synchronous generator, and the output current of the stator power winding of the synchronous generator, the input power, speed, output power, output torque, and motor efficiency of the motor under test can be obtained, thus eliminating the need for the speed sensor and torque sensor that are necessary for the traditional motor loading performance test system, simplifying the test system, and reducing the cost. However, there are the following deficiencies: single test and lack of comparison, it usually only tests a single motor or speed reducer, and cannot evaluate the matching effects of multiple solutions simultaneously, resulting in low selection efficiency and difficulty in quickly screening out the best combination; poor working condition adaptability, the existing methods are difficult to simulate the performance differences of the motor and speed reducer under different installation positions and load conditions, affecting the reliability of actual applications; test feedback lag, lack of efficient sensor data acquisition and analysis means, resulting in difficulty in quickly quantifying the matching effects of the motor and speed reducer and affecting the efficiency of optimization decisions. Limited load simulation, the existing test platforms usually adopt a fixed load method and cannot flexibly adjust the load characteristics to adapt to different application scenarios, restricting the versatility of the test methods.

[0044] To solve the above technical problems, the present application proposes a method and system for selecting and verifying a device under test, aiming to improve the efficiency, accuracy, and applicability of testing. Its main objectives include: improving testing efficiency by simultaneously testing multiple sets (e.g., four sets) of combinations of motors under test and reduction modules of the same specification through a set of selection and verification system (test board), and realizing comparative analysis of multiple groups of data to improve the efficiency of selection and verification. Enhancing the adaptability of the test working conditions by setting corresponding test signals according to different installation positions and simulating different working conditions in combination with a generator and an electronic load / slide rheostat to ensure that the test results are more representative. The method will be described first below, and then the system and others will be described.

[0045] Method embodiment.

[0046] See Figure 1 , Figure 1 is a schematic flowchart of a method for selecting and verifying a device under test provided by an embodiment of the present application.

[0047] An embodiment of the present application provides a method for selecting and verifying a device under test. The device under test includes multiple modules to be tested arranged at different positions, and each module to be tested includes a motor under test and a reduction module under test connected by a shaft; the method includes:

[0048] S101, obtaining combined test information corresponding to the test positions of each module to be tested, where the combined test information includes multiple sets of preset data, and each set of preset data includes a load test data and a test signal data;

[0049] First, for each module to be tested at different positions in the device under test, obtain the corresponding combined test information. The combined test information contains multiple sets of preset data, and each set of preset data consists of a load preset data and a test signal data. It can be considered that the preset data is preset according to the actual application scenario and performance requirements of the device under test and is used to simulate the operating state of the device under different working conditions.

[0050] S102, for each module to be tested, perform tests using its corresponding test device according to the combined test information, and obtain the test data when each set of preset data is used; determine whether the module to be tested meets the preset test requirements when tested with each set of predicted data in the combined test information;

[0051] For each module to be tested, use the corresponding test device to perform tests according to each set of preset data in the combined test information. Adjust the load conditions of the test device according to the load test data, and at the same time send a control signal to the module to be tested according to the test signal data. During each test condition, collect the operating data of the module to be tested in real time, such as the voltage, current, and speed of the motor and the operating state of the reduction module.

[0052] By analyzing the collected test data, it can be determined whether each module under test meets the preset test requirements under the test conditions corresponding to each group of preset data. The preset test requirements include, for example, performance indicators (such as rotational speed range, torque output, etc.) and stability indicators (such as vibration amplitude, noise level, etc.).

[0053] S103. When each of the modules under test meets the preset test requirements, it is considered that the device under test meets the verification requirements for selection. If all the modules under test meet the preset test requirements under all test conditions, it is considered that the device under test has passed the selection verification, and its design and performance meet the expected application requirements.

[0054] Thus, by simultaneously testing multiple modules under test and comprehensively evaluating them using multiple groups of preset data, a comprehensive performance test can be completed in a relatively short time, improving the test efficiency and shortening the development cycle. By simulating different load and signal conditions, the performance of the device under test in various actual working condition environments can be comprehensively evaluated, ensuring the accuracy and reliability of the test results, and helping to screen out the optimal device combination. By conducting verification in the early selection stage, rework and modification due to unqualified performance in the later stage can be reduced, lowering the development cost and project risk.

[0055] In summary, this technical solution provides an efficient, flexible and comprehensive method for verifying the selection of a device under test, which helps to ensure the performance and reliability of the device, while optimizing the development process and reducing costs and risks.

[0056] In some embodiments, the method further includes: when at least one module under test does not meet the preset test requirements, generating a prompt message and sending it to the user device, where the prompt message is used to instruct the user to replace the device under test with a new one for selection verification.

[0057] When at least one module under test does not meet the preset test requirements during the test process, a corresponding prompt mechanism is triggered. Specifically, during the test process, the system monitors the operation data of each module under test in real time and compares it with the preset test requirements. If it is found that a certain module under test does not meet the preset requirements under a certain combination of preset data, this situation is recorded. At the same time, a prompt message is generated, which includes the specific position of the module that does not meet the requirements, the test conditions, and the specific parameters that do not meet the standard. The prompt message is sent to the user device (such as a computer, mobile phone, etc.) in the form of a text message, voice, etc. through the communication module to notify the user that the current test has failed. After receiving the prompt message, the user can judge whether to replace the device under test with a new one or adjust the existing device and retest according to the detailed content in the message.

[0058] Thus, through the automated monitoring and prompting mechanism, it is possible to quickly identify the modules under test that do not meet the requirements, avoiding the cumbersome process of manual inspection one by one, and improving the test efficiency. At the same time, it ensures that only the devices that fully meet the requirements can pass the verification, enhancing the accuracy of the test results. The automated prompting reduces the need for manual monitoring, reduces the risk of misjudgment caused by human negligence, and improves the reliability of the test process. Users can receive feedback on the test results in a timely manner and make a quick response, such as replacing the device or adjusting the test strategy, shortening the overall test cycle.

[0059] In summary, through the introduction of an automated prompting mechanism, this technical solution significantly improves the efficiency and accuracy of the test process, while reducing manual intervention, providing real-time feedback, enhancing the user experience, and reducing development costs and risks.

[0060] See Figure 2 , Figure 2 which is a schematic flowchart of the process for obtaining combined test information provided by an embodiment of the present application.

[0061] In some embodiments, the method for obtaining the combined test information includes:

[0062] S201, obtain test strategy information, where the test strategy information includes a plurality of input test signal information and a plurality of load test information for each module under test in the device under test;

[0063] It can be considered that for each module under test in the device under test, various input test signal information and load test information that may be encountered in different application scenarios are collected. The input test signal information is used to drive the module under test to run, while the load test information is used to simulate the load conditions in the actual working conditions. The input test signal information and the load test information are integrated into test strategy information to provide basic data for subsequent pairing combinations.

[0064] S202, obtain a plurality of pairing combinations obtained by pairing the plurality of load test information with the plurality of input test signal information according to the one-to-one pairing principle.

[0065] According to the one-to-one pairing principle, each load test information is paired with an input test signal information to form a plurality of pairing combinations. The pairing combinations are integrated into combined test information to guide the subsequent test process and ensure that each module under test can be tested under a variety of different load and signal conditions.

[0066] Thus, by pairing and combining various load test information and input test signal information, it is possible to simulate various working conditions that the device under test may encounter in actual applications, ensuring the comprehensiveness and accuracy of the test. By pre-defining test strategy information and generating combined test information, the test process can be systematically organized, reducing manual intervention and improving test efficiency.

[0067] In some embodiments, the device under test is applied to an intelligent cleaning device, which includes four modules under test, located at the front left, rear left, front right, and rear right positions of the intelligent cleaning device respectively.

[0068] The intelligent cleaning device includes four modules under test, located at the front left, rear left, front right, and rear right positions of the device respectively. Each module under test includes a motor under test and a reduction module under test connected by a shaft, and is used to be set at the above positions of the intelligent cleaning device after the test.

[0069] Thus, by simultaneously testing the four modules under test and comprehensively evaluating them using multiple sets of preset data, a comprehensive performance test can be completed in a relatively short time, improving test efficiency and shortening the development cycle. By simulating the load and signal conditions corresponding to four different positions, the performance of the intelligent cleaning device under various actual working conditions can be comprehensively evaluated, ensuring the accuracy and reliability of the test results, and helping to screen out the optimal device combination.

[0070] In some embodiments, the testing according to the combined test information using its corresponding test device includes:

[0071] Adjust the load parameters of the test device according to the load test data in the combined test information; control the module under test to conduct a test according to the test signal data corresponding to the load test data.

[0072] The test device first analyzes the combined test information and extracts the load test data and test signal data therein. Each set of test data corresponds to a specific test condition, including a load test data and a test signal data. According to the load test data in the combined test information, adjust the parameters of its load simulation module. The load simulation module is used to simulate the load conditions in actual working conditions, such as different ground resistances, load weights, etc.

[0073] According to the test signal data in the combined test information, the test device sends a control signal to the module under test. The control signal is used to drive the motor and reduction module of the module under test to operate under specific conditions, such as different speeds, torques, etc.

[0074] After adjusting the load parameters and sending the control signal, the test device starts the test to make the module under test operate under the simulated load conditions. During the test, operating data of the module under test, such as the voltage, current, and speed of the motor, and the operating state of the reduction module, are collected in real time.

[0075] Thus, by parsing the combined test information and adjusting the load parameters, the load conditions in the actual working conditions can be accurately simulated. That is, the load parameters and control signals can be flexibly adjusted according to different test requirements to adapt to various test scenarios.

[0076] In some embodiments, the method for determining whether each set of predicted data in the combined test information of the module under test meets the preset test requirements includes:

[0077] Obtain the numerical range of each test data from the preset test requirements; when each set of test data of the module under test in the combined test information is within its corresponding numerical range, it is considered to meet the preset test requirements.

[0078] Compare the actually collected operating data with the preset numerical range. If the actually collected operating data of the module under test in all test combinations are within their corresponding numerical ranges, it is considered that the module meets the preset test requirements; otherwise, it is considered not to meet the preset test requirements. Thus, through the clear comparison of numerical ranges, the performance of the module under test under different test conditions can be accurately evaluated to ensure that it meets the design specifications and performance indicators.

[0079] As an example, a method for selecting and verifying a device under test is provided. The device under test is applied to an intelligent cleaning device and includes four modules under test, which are respectively located at the front left, rear left, front right, and rear right positions of the intelligent cleaning device; the method includes:

[0080] Obtain test strategy information, where the test strategy information includes multiple input test signal information and multiple load test information for each module under test in the device under test; obtain multiple pairing combinations obtained by pairing the multiple load test information and the multiple input test signal information according to the one-to-one pairing principle; in this case, the combined test information includes multiple sets of preset data, and each set of preset data includes a load test data and a test signal data;

[0081] For each module under test, adjust the load parameters of the test device according to the load test data in the combined test information; control the module under test to perform tests according to the test signal data corresponding to the load test data, and obtain the test data when each set of preset data; obtain the numerical range of each test data from the preset test requirements. When each set of test data of the module under test in the combined test information is within its corresponding numerical range, it is considered to meet the preset test requirements; otherwise, it is considered not to meet the preset test requirements;

[0082] When each of the modules under test meets the preset test requirements, it is considered that the device under test meets the verification requirements for selection;

[0083] When at least one module to be tested does not meet the preset test requirements, a prompt message is generated and sent to the user device, and the prompt message is used to instruct the user to replace the new device to be tested for type selection verification.

[0084] As an example, a method for verifying the type selection of a device to be tested is provided. The device to be tested is applied to an intelligent cleaning device, and the intelligent cleaning device includes 4 drive motor modules (left front LF, left rear LR, right front RF, right rear RR), and its load response characteristics and signal stability need to be verified. The test strategy information includes:

[0085] Parameter type Left front LF Left rear LR Right front RF Right rear RR Input test signal 12V / 100Hz 12V / 120Hz 24V / 80Hz 24V / 100Hz Load test information 5Ω / 10N·m 8Ω / 8N·m 6Ω / 12N·m 10Ω / 6N·m

[0086] Test execution process (taking the left front LF module as an example)

[0087]

[0088] It can be determined that the left front LF module meets the determination. When all four modules meet the determination, it is considered that the device to be tested meets the verification requirements for type selection. If at least one module does not meet the requirements, a prompt message is generated, and it is recommended to replace the new device to be tested for testing.

[0089] A method for verifying the type selection of a device to be tested proposed in this embodiment can test multiple modules to be tested simultaneously to solve the problems of single test and lack of comparison. Through the comparative analysis of multiple groups of data, the best combination can be quickly screened out, improving the type selection efficiency. At the same time, by obtaining combined test information, including multiple groups of preset data (each group includes a load test data and a test signal data), the performance of the device to be tested under different working conditions can be comprehensively evaluated, ensuring the accuracy and reliability of the test results. To solve the problem of poor working condition adaptability, by adjusting the load parameters of the test equipment to simulate different load conditions in actual working conditions (such as different ground resistances, load weights, etc.), the performance of the device to be tested in various actual applications can be comprehensively evaluated. Corresponding test signals and load conditions are set for different positions of the intelligent cleaning device (such as left front, left rear, right front, right rear) to ensure that the test results are more representative. To solve the problem of lagging test feedback, when at least one module to be tested does not meet the preset test requirements, a prompt message will be automatically generated and sent to the user device to notify the user to replace the new device to be tested or adjust the test strategy, reducing manual intervention and improving the test efficiency and accuracy. During the test process, the operation data of the module to be tested (such as the voltage, current, and speed of the motor, and the operation status of the reduction module, etc.) are collected in real time and analyzed to ensure the timeliness and accuracy of the test results. To solve the problem of limited load simulation, by analyzing the combined test information and adjusting the load parameters, the load conditions in actual working conditions can be accurately simulated. When using an electronic load, the load parameters can be dynamically adjusted through an external control signal to achieve automated load simulation, improving the flexibility and efficiency of the test.

[0090] In summary, the model selection verification method of the present application effectively solves the problems of single testing, poor working condition adaptability, lagging test feedback, and limited load simulation in the related art through technical means such as multi-module simultaneous testing, flexible load simulation, real-time data collection and analysis, and an automated prompt mechanism, significantly improving the efficiency, accuracy, and applicability of the testing.

Among them, the information acquisition device is used to collect the operation data of the to-be-tested module during the test in real time, such as the voltage, current, and rotation speed of the motor, as well as the operation status of the reduction module, etc.; and convert the collected analog signals into digital signals. For example, it includes a voltage sensor, a current sensor, a rotation speed sensor, etc., which are used to collect the operation data of the to-be-tested module. It also includes a signal conditioning circuit, which is used to amplify, filter, etc. the signals output by the sensors to improve the quality and stability of the signals. It also includes an analog-to-digital converter (ADC), which is used to convert analog signals into digital signals for subsequent digital processing. It also includes a communication interface, which is used to transmit the processed data to the controller. The communication interface is, for example, USB or RS-232.
