Description

Technical Field

[0001] The present invention relates to the technical field of data transmission, and in particular to a data line bidirectional transmission test method, system, equipment and medium thereof. Background Art

[0002] In today's information society, data has become a bridge connecting the virtual and real worlds. People share, communicate and process information through data transmission. Whether it is file transfer and video conferencing at work, or mobile phone charging and music playing in life, data cables are indispensable. Therefore, the performance and quality of data cables play a vital role in ensuring the efficiency and stability of data transmission.

[0003] As an important medium for data transmission, data cables are responsible for transmitting information from one device to another. In the process of two-way transmission, data cables not only need to be able to send data accurately, but also need to be able to receive data completely to ensure the correct transmission of information. If the performance of the data cable is poor or there are quality problems, it may cause problems such as slow data transmission speed, data loss or transmission errors, thus affecting people's normal work and life.

[0004] Therefore, it is particularly important to test the bidirectional transmission performance of the data line. Through testing, the transmission capacity, stability and reliability of the data line can be fully evaluated, providing strong support for the production and quality control of the data line. At the same time, the test can also help users understand the performance characteristics of the data line, choose the data line that suits their needs, and improve the efficiency and stability of data transmission. However, there are still some problems in testing the bidirectional transmission performance of the data line:

[0005] 1. Some test methods are too simple, only checking the physical connection status of the data line, but ignoring the actual performance of the data during transmission. This test method often cannot accurately evaluate the bidirectional transmission capability of the data line, resulting in data transmission errors or slow speeds in actual use;

[0006] Second, although some test methods have been tested for data transmission, there are still some shortcomings in the test methods, such as only one-way transmission color measurement, cumbersome test steps, insufficient test range, and unrealistic test environment. These problems may lead to inaccurate test results and fail to truly reflect the actual performance of the data cable;

[0007] To this end, a data line bidirectional transmission test method, system, device and medium thereof are proposed. Summary of the invention

It should be noted that if there are substantially the same results, the method of the present application is not limited to the method of FIG. Figure 1 The process sequence shown is limited. Figure 1-Figure 2 As shown: A data line bidirectional transmission test method, comprising the following steps:

[0053] Step 1: Visually inspect the data cable to be tested. This step is crucial because the physical condition of the data cable directly affects its transmission performance. Check whether the data cable has obvious physical damage, such as cracks, wear or bends. Also check whether the plug of the data cable is oxidized, deformed or dirty. These physical factors may affect the transmission quality and stability of the data cable.

[0054] Step 2: Plug both ends of the data cable into the data interfaces of the two devices. This step requires ensuring that the connection between the data cable and the device is stable and reliable to avoid loosening or falling off during the test.

[0055] Step 3. Observe the recognition status and connection display status of the two devices. By checking the system notification or settings of the device, we can confirm that the data cable has been correctly identified and configured. This step ensures that the communication between the data cable and the device is normal, laying the foundation for subsequent tests.

[0056] Step 4: Perform a two-way file transfer test and a two-way data transfer volume test on the data cable. The two-way file transfer test and the two-way data transfer volume test are the core test links of the two-way transmission test of the data cable. Through the two-way file transfer test and the two-way data transfer volume test, the transmission performance of the data cable can be fully evaluated, including the transmission speed, stability, and the performance under different file types and sizes. This evaluation helps to understand the performance of the data cable in actual use, so as to determine whether it meets the needs of users;

[0057] Step 5: Test the transmission stability of the data cable by transmitting data for several hours and monitoring the stability, transmission speed and data error rate of the data cable connection under high temperature, low temperature and humid environment conditions, so as to simulate various environmental conditions that the data cable may encounter in actual use, and then evaluate its performance more comprehensively;

[0058] Step 6: Test the current, voltage, electromagnetic interference and safety of the data line. These tests are designed to ensure that the data line will not cause interference or safety hazards to other devices or systems while transmitting data;

[0059] Step 7. Generate a comprehensive evaluation report on the bidirectional transmission capability of the data line based on the test data. The comprehensive evaluation report lists in detail the various data indicators and results of the test process, providing strong support for the design and production of the data line.

[0065] Step 3. After the transfer is completed, the integrity and error rate of the file will be automatically checked;

[0066] Step 4. Repeat steps 1 to 3 to transfer files from the second device to the first device.

[0067] Step 5. Repeat steps 1 to 4 to transfer files larger than 1GB, file collections, or multiple files simultaneously. Automatically record any exceptions or interruptions during the transfer process and monitor the stability of the transfer speed.
