Description

Technical Field

[0001] This application relates to the field of data cable performance testing technology, and in particular to a data cable electrical performance testing system. Background Technology

[0002] A data cable is a cable assembly used to transmit data signals and power between devices. Its core function is to transmit digital signals and DC power. Electrical performance testing is a series of quantitative tests on the inherent electrical characteristics of a data cable to verify whether it meets design specifications and safety standards, thereby effectively ensuring product functionality and safety.

[0003] Regarding the aforementioned technologies, existing methods for testing the electrical performance of data cables typically involve using multiple independent dedicated testing instruments (such as network analyzers for impedance measurement, digital bridges for resistance measurement, and oscilloscopes for signal measurement). This requires personnel to test each data cable individually using several instruments. Since each instrument has a different interface and parameter settings, testers must manually adjust the interface and parameters based on memory or instructions for each test, increasing workload and reducing efficiency in testing the electrical performance of data cables. Therefore, improvements are needed. Summary of the Invention

[0004] To improve the efficiency of testing the electrical performance of data cables, this application provides a data cable electrical performance testing system.

[0005] This application provides a data cable electrical performance testing system, which adopts the following technical solution: A data cable electrical performance testing system includes several testing devices, each of which is used to perform different electrical performance tests on the data cable. It also includes a human-machine interaction module and a control module. Each testing device and the human-machine interaction module are controlled by the control module. Each testing device is used to feed back the detected data to the control module. The human-computer interaction module is used to provide a visual operation interface and to obtain detection commands triggered by the user. The visual interface displays detection items that can be set by the user via touch and correspond to the electrical performance of the data cable. Each detection item is set with corresponding parameters. The human-computer interaction module is used to list specific detection items in the visual operation interface. Correspondingly, the detection command includes detection items that can be selected by the user via touch and corresponding parameters. The control module is used to acquire the detection items in the detection instruction, and to control the corresponding detection equipment to set parameters according to the parameters included in the detection items. The control module is also used to receive and integrate the data fed back by the detection equipment, and to control the human-machine interaction module to display the fed-back data. By adopting the above technical solution, compared with the existing technology, when inspecting data cables, staff need to test each cable individually through several testing instruments, and manually adjust the operation interface and parameters of the dedicated testing instruments according to memory or instructions for each test, thus increasing the workload of staff and reducing the efficiency of testing the electrical performance of data cables. This application, through the setting of the human-machine interface module and control module, allows staff to select the corresponding test items on the visual operation interface provided by the human-machine interface module after connecting the testing equipment to the data cable. This allows staff to set appropriate parameters for the corresponding test items, and the control module can control the corresponding testing equipment to adjust the parameters according to the set parameters, thereby realizing the testing of multiple cables. The unified parameter debugging of testing equipment integrates complex and discontinuous manual operation processes into a smooth "one-click" automated process. This reduces and eliminates time-consuming steps such as instrument setup and manual recording, significantly shortening the single test time and increasing production capacity. At the same time, the software can solidify the optimal test parameters and processes, reducing fluctuations in human operation and subjective interpretation errors, making the test results objective and repeatable, significantly improving reliability. Furthermore, it eliminates the need for operators to be proficient in various complex instruments, reducing training costs and entry barriers, while also reducing quality risks caused by human factors. In addition, the electronic and structured storage of data provides strong data support for production process analysis, quality traceability, yield improvement, and process optimization, realizing the digital transformation of the quality inspection process and making it easy to expand new testing functions and adapt to new product models.

[0006] Preferably, the control module further includes a data retrieval unit, which is used to store various data cable types and specific detection items corresponding to the data cable types. The human-computer interaction module is used to obtain the data cable type of the data cable to be detected based on the detection command triggered by the user and to feed it back to the data retrieval unit. The data retrieval unit is used to retrieve the specific items corresponding to the data cable type after receiving the data cable type feedback from the human-computer interaction module and send them to the human-computer interaction module. The human-computer interaction module is used to receive the specific detection items sent by the data retrieval unit and display the retrieved specific items through a visual interface for the user to select.

[0007] By adopting the above technical solution and setting the data retrieval unit, the data retrieval unit can store various data cable types and the corresponding test items, thereby effectively facilitating the retrieval by staff through the human-machine interaction module. This allows the control module to display the parameters corresponding to the test items selected by the interface interaction module. Furthermore, the electronic and structured storage of data provides strong data support for production process analysis, quality traceability, yield improvement, and process optimization. It is also easy to expand new test functions and adapt to new product models, thereby improving the adaptability of this application.

[0008] Preferably, the control module further includes a data comparison unit, which is used to compare the detection data detected by the corresponding detection device with the pre-stored standard data, and to obtain a judgment result on whether the detection is qualified based on the comparison result. After obtaining the judgment result, the control module is controlled to display the judgment result on the visual operation interface.

[0009] By adopting the above technical solution and setting the data comparison unit, the data comparison unit can compare the data detected by the corresponding testing equipment with the pre-stored standard data, thereby obtaining the judgment result of whether the test is qualified based on the comparison result, and controlling the human-computer interaction module to display the judgment result of whether the test is qualified on the visual operation interface, which effectively facilitates the staff to know the test results and saves the time required for manual comparison.

[0010] Preferably, the control module further includes a data processing unit, which is used to process and analyze the data detected by the corresponding detection device, and control the human-computer interaction module to draw a correspondence diagram between the detected data on the visual operation interface.

[0011] By adopting the above technical solution and setting the data processing unit, the data processing unit can process and analyze the data detected by the corresponding detection equipment, and control the human-computer interaction module to draw the correspondence diagram between the detected data on the visual operation interface, so as to facilitate relevant personnel to understand the changes in the detected data more clearly, thereby effectively ensuring the detection results.

[0012] Preferably, the device also includes two fixtures, with each probe on the testing device mounted on a corresponding fixture. Each fixture is provided with a conductive sheet and a clamping mechanism. The clamping mechanism is used to clamp the data line inside the fixture, and the end of the data line is connected to the corresponding probe head through the conductive sheet.

[0013] By adopting the above technical solution and setting the fixture, the operator can clamp the end of the data cable to be tested through the clamping mechanism, thereby ensuring the stability of the data cable and enabling the data cable to be stably connected to the probe head through the conductive sheet, thus effectively ensuring the testing effect of the data cable.

[0014] Preferably, the fixture is further provided with an adjustment mechanism, which includes an adjustment frame and an adjustment component. One end of the adjustment frame is rotatably connected to the fixture. One side of the conductive sheet is embedded in the corresponding adjustment frame, and its end extends out of the adjustment frame and contacts the data cable. The adjustment component is used to drive the adjustment frame to rotate.

[0015] By adopting the above technical solution and setting the adjustment mechanism, when it is necessary to test data cables of different diameters, the operator can drive the adjustment frame to rotate through the adjustment component, thereby moving one side of the conductive sheet and adjusting the position of the end of the conductive sheet so that the end of the conductive sheet can contact the side wall of the data cable of different diameters. This effectively improves the adaptability of this application and eliminates the need to replace fixtures of different sizes, which facilitates the operation of the operator and saves the time required for replacement.

[0016] Preferably, the clamping mechanism includes a clamping frame and an abutment frame, the abutment frame and the clamping frame are located on opposite sides of the data cable, the abutment frame is disposed on the fixture, one end of the abutment frame away from the abutment frame is rotatably connected to the fixture, and the other end of the abutment frame is used to abut against the outer wall of the data cable after rotation, and push the data cable against the abutment frame.

[0017] By adopting the above technical solution and configuring the clamping mechanism, after one end of the data cable is inserted into the fixture, the operator can rotate the clamping frame so that one end of the clamping frame abuts against the side wall of the data cable and pushes the data cable against the abutting frame. Thus, the clamping frame and the abutting frame together clamp and fix the data cable, thereby fixing the data cable and effectively facilitating the operator's operation.

[0018] Preferably, the abutment frame is slidably connected to the fixture, and the sliding direction is different from the length direction of the data cable on the fixture. The clamping mechanism also includes a linkage component. The adjusting frame drives the abutment frame to slide through the linkage component so that the abutment frame abuts against the outer wall of the data cable.

[0019] By adopting the above technical solution, the setting of the abutment frame and the linkage component allows the adjustment frame to slide through the linkage component when the adjustment frame rotates. This enables the abutment frame to adapt to changes in the diameter of the data cable, effectively reducing the probability of excessive damage to the data cable due to its excessive diameter or difficulty in clamping and fixing it due to its excessively small diameter after the data cable is replaced. This effectively ensures the clamping and fixing effect of the data cable.

[0020] Preferably, the linkage component includes a linkage frame, one end of which is rotatably connected to the adjustment frame, and the other end of which is rotatably connected to the abutment frame.

[0021] By adopting the above technical solution and setting the linkage frame, when the adjusting frame rotates, the adjusting frame can drive the abutment frame to slide through the linkage frame, thereby realizing the sliding of the abutment frame. At the same time, it also realizes the linkage between the adjusting frame and the abutment frame, so that the operator does not need to drive the abutment frame to slide, which effectively facilitates the operator's operation.

[0022] Preferably, the adjustment assembly includes a sliding frame, a transmission frame, and a locking member. The sliding frame is slidably connected to the fixture. One end of the transmission frame is rotatably connected to the sliding frame, and the other end is rotatably connected to the adjustment frame. The locking member is used to lock the sliding frame and the fixture after the sliding frame has slid.

[0023] By adopting the above technical solution and setting the adjustment component, when it is necessary to drive the adjustment frame to rotate, the operator can release the locking between the sliding frame and the fixture through the locking device, and after release, drive the sliding frame to slide. This allows the sliding frame to drive the adjustment frame to rotate through the transmission frame, thereby realizing the adjustment of the position of the conductive sheet end. This effectively facilitates the operator's operation and ensures the connection effect of data cables of different diameters.

[0024] In summary, this application includes at least one of the following beneficial technical effects: The human-machine interface (HMI) and control modules are designed so that after connecting the testing equipment to the data cable, operators can select the corresponding testing items on the visual interface provided by the HMI. This allows operators to set appropriate parameters for each testing item, and the control module can then adjust the parameters of the corresponding testing equipment accordingly. This enables unified parameter debugging of multiple testing devices, integrating complex and discontinuous manual operation processes into a smooth "one-click" automated process. It reduces and eliminates time-consuming steps such as instrument setup and manual recording, significantly shortening the single testing time and increasing production capacity. At the same time, the software can solidify the optimal test parameters and processes, reducing fluctuations in human operation and subjective interpretation errors, making the test results objective and repeatable, significantly improving reliability. Furthermore, operators do not need to be proficient in various complex instruments, reducing training costs and entry barriers, and reducing quality risks caused by human factors. In addition, the electronic and structured storage of data provides strong data support for production process analysis, quality traceability, yield improvement, and process optimization, realizing the digital transformation of the quality inspection process and facilitating the expansion of new testing functions and adaptation to new product models. The data retrieval unit is configured to store various data cable types and corresponding test items, thus facilitating retrieval by staff through the human-machine interface module. This allows the control module to display the corresponding parameters based on the test items selected by the interface module. Furthermore, the electronic and structured storage of data provides strong data support for production process analysis, quality traceability, yield improvement, and process optimization. It is also easy to expand new test functions and adapt to new product models, thereby improving the adaptability of this application. The adjustment mechanism allows operators to rotate the adjustment frame by adjusting the components when testing data cables of different diameters. This causes one side of the conductive sheet to move, thereby adjusting the position of the conductive sheet end. This ensures that the end of the conductive sheet can contact the sidewall of the data cable of different diameters, effectively improving the adaptability of this application. Furthermore, it eliminates the need to replace fixtures of different sizes, facilitating operator operation and saving time required for replacement. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a data cable electrical performance testing system. (Refer to...) Figure 1 and Figure 2 The data cable electrical performance testing system includes several testing devices 1, a human-machine interface module 2, and a control module 3. The testing devices 1 are used to perform different electrical performance tests on the data cable. Each testing device 1 and the human-machine interface module 2 are controlled by the control module 3, and each testing device 1 is used to feed back the detected data to the control module 3. The human-machine interface module 2 provides a visual operation interface and is used to receive user-triggered testing commands. The visual interface displays test items that can be set by the user via touch and correspond to the electrical performance of the data cable, with corresponding parameters set for each test item. The human-machine interface module lists the specific test items within the visual operation interface. Correspondingly, the testing commands include test items that can be selected by the user via touch and their corresponding parameters. The control module 3 is used to obtain the test items in the testing commands and, based on the parameters included in the test items, controls the corresponding testing device 1 to set the parameters. The control module 3 receives and integrates the data fed back by the testing devices 1 and controls the human-machine interface module 2 to display the fed-back data.

[0032] Reference Figure 1 and Figure 2In this embodiment, several testing devices 1 are configured as impedance testers, cable testers, vector network analyzers, high-voltage testers, etc., the control module 3 is configured as an industrial control computer, and the human-machine interaction module 2 is configured as a touch screen. The industrial control computer is equipped with a graphical user interface application developed using C language, WPF framework, or other programming programs. The control module 3 includes a data retrieval unit 31, which is configured as an SQLite relational database or other database. The impedance tester, cable tester, vector network analyzer, high-voltage tester, and touch screen are all communicatively connected to the industrial control computer.

[0033] Reference Figure 1 and Figure 2 In this embodiment, the graphical user interface application provides a complete visual operation interface on a touch screen, including a product model selection area, a test item configuration area, a parameter setting area, a process control area, and a test information display area. Specifically, the product model selection area is configured as a drop-down list box, a menu for selection, or a checkbox, with content dynamically loaded from an SQLite relational database. The test item configuration area is configured as a set of checkboxes listing items such as continuity test, insulation test, signal completion test, and withstand voltage test; users can select some or all of these items. When a specific test item is selected, the parameter setting area dynamically displays input boxes for relevant parameters (such as the voltage value for the withstand voltage test) for operators to select or input. The process control area includes virtual buttons such as "Start Test," "Pause," "Stop," and "Export Report" for operator operation.

[0034] Reference Figure 1 and Figure 2 The detection information display area is set as a text and graphic area for scrolling display of the current test step, status, and prompts. All operations performed by the operator are captured on the visual operation interface and encapsulated into structured instruction objects, which are sent to the aforementioned industrial control computer via an internal message queue. This allows the industrial control computer to call the corresponding test sequence script in the SQLite relational database, providing feedback to the testing equipment. Testing equipment 1 can then adjust its parameters based on the received information to adapt to the corresponding testing items for different specifications of data cables, thereby enabling testing equipment 1 to perform testing on the data cables.

[0035] Reference Figure 1 and Figure 2During the testing process, the testing device 1 feeds back the detected data (such as continuity resistance, insulation resistance, test signals, etc.) to the industrial control computer, which receives the feedback testing data. The control module 3 also includes a data comparison unit 32 and a data processing unit 33. The data comparison unit 32 can call up standardized data (i.e., qualified data) pre-stored in the SQLite relational database and compare the data detected by the testing device 1 with the standardized data. When the data detected by the testing device 1 is within the range of the standardized data, a qualified conclusion is drawn, and the touch screen is controlled to display the qualified conclusion (specifically, the text "qualified") on the testing information display area. When the detected data is outside the range of the standardized data, a unqualified conclusion is drawn, and the touch screen is controlled to display the unqualified conclusion (specifically, the text "unqualified") on the testing information display area.

[0036] Reference Figure 1 and Figure 2 The data processing unit 33 has a built-in library of various analysis algorithms and is used to process and analyze the data detected by the corresponding detection device 1. It also controls the human-computer interaction module 2 to draw a graph of the correspondence between the detection data on the detection information display area, such as a scatter plot (function graph or correspondence graph), curve graph or table. For example, it displays the impedance curve and other graphical data in the form of a two-dimensional coordinate system graph on the detection information display area.

[0037] Reference Figure 1 and Figure 3 The data cable electrical performance testing system also includes two fixtures 4. Each fixture 4 has an opening on one side wall for inserting the end of the data cable. Each fixture 4 also has an opening on its top for inspecting or replacing internal components. Each fixture 4 has a cover plate 41 on its top. The end of the cover plate 41 away from the opening on the side wall is rotatably connected to the housing of the fixture 4 via a pin. The other end of each cover plate 41 has a protrusion for snap-fit ​​connection with the housing of the fixture 4, facilitating the opening of the cover plate 41. Both the protrusion and the snap-fit ​​method are existing technologies and will not be described further. The bottom of the cover plate 41 abuts against the top of the data cable inside the housing of the fixture 4, thus fixing the data cable vertically.

[0038] Reference Figure 3 and Figure 4 Each fixture 4 has a conductive sheet 5 and an adjustment mechanism 6 on its housing. In this embodiment, each fixture 4 has two conductive sheets 5, and the two conductive sheets 5 are located on both sides of the corresponding fixture 4 to accommodate the number of probes required by different detection devices 1.

[0039] Reference Figure 3 and Figure 4 One end of each conductive sheet 5 is embedded in the housing of the fixture 4, and the top of each conductive sheet 5 is used to contact the end of the corresponding probe (i.e., the probe connection line, which can be plugged into different detection devices 1) to achieve communication. The conductive sheet 5 is a copper spring, and the way the conductive sheet 5 is connected to the probe is existing technology, so it will not be described in detail here.

[0040] Reference Figure 3 and Figure 4 Each adjustment mechanism 6 includes an adjustment frame 61 and an adjustment component 62. In this embodiment, the number of adjustment frames 61 is set to two, and they are located on opposite sides of the data cable. The end of each adjustment frame 61 away from the rotatable connection end of the cover plate 41 is rotatably connected to the housing of the fixture 4 via a pin, and the rotation direction is vertical.

[0041] Reference Figure 3 and Figure 4 Each adjustment bracket 61 has a groove on its top for embedding one side of a corresponding conductive sheet 5. One side of each conductive sheet 5 is embedded in the groove of the corresponding adjustment bracket 61, and its end extends towards the side of the cover plate 41 and out of the adjustment bracket 61, abutting against the end sidewall of the data cable, so that the data cable connects to the corresponding probe head through the conductive sheet 5. In this embodiment, the lengths of the two conductive sheets 5 within the same fixture 4 housing are not the same, so that the two conductive sheets 5 contact different points along the length of the data cable.

[0042] Reference Figure 3 and Figure 4 Each adjustment component 62 includes a sliding frame 621, a transmission frame 622, and a locking member 623. In this embodiment, the number of transmission frames 622 is set to two, corresponding to the two adjustment frames 61. Each sliding frame 621 is located inside the housing of the corresponding fixture 4, below the end of the data cable, and is slidably connected to the housing of the fixture 4 through a sliding groove, with the sliding direction being the length direction of the cover plate 41.

[0043] Reference Figure 3 and Figure 4Two transmission frames 622 are located at both ends of the corresponding sliding frame 621 along its own length direction. One end of each frame is rotatably connected to the corresponding sliding frame 621 via a pin. The other end of each frame is inclined towards the corresponding adjusting frame 61 and is rotatably connected to the corresponding adjusting frame 61 via a pin. This allows the sliding frame 621 to drive the adjusting frame 61 to rotate through the transmission frame 622 when the sliding frame 621 slides. This causes the adjusting frame 61 to move one side of the conductive sheet 5, thereby adjusting the distance between the two conductive sheets 5 to accommodate data cables of different diameters. In this embodiment, when the data cable contacts each conductive sheet 5, it will push the conductive sheet 5 to move to a certain extent, so that the end of the conductive sheet 5 abuts against the side wall of the data cable.

[0044] Reference Figure 3 and Figure 4 The locking component 623 includes a locking screw 6231. One end of the locking screw 6231 is located outside the body of the corresponding fixture 4, and the other end is threaded (not shown in the attached drawing) and extends into the interior of the housing of the corresponding fixture 4. It is inserted into the side wall of the corresponding sliding frame 621 and threadedly connected to the corresponding sliding frame 621. When the locking screw 6231 is tightened, its end can generate friction by abutting against the outer side wall of the fixture 4 housing, thereby locking the sliding frame 621. A strip-shaped groove is also provided on the side wall of the fixture 4 housing for the locking screw 6231 to move. The extension direction of the strip-shaped groove is the same as the sliding direction of the sliding frame 621 and communicates with the cavity inside the fixture 4 housing so that the end of the locking screw 6231 can pass through.

[0045] Reference Figure 3 and Figure 4 Each fixture 4 is further provided with a clamping mechanism 7, each clamping mechanism 7 including a clamping frame 71, an abutment frame 72, and a linkage component 73, each linkage component 73 including a linkage frame 731. The clamping frame 71 and the abutment frame 72 are both located on the side of the fixture 4 housing away from the rotating connection end of the cover plate 41, and are respectively located on different sides of the data cable. The abutment frame 72 is slidably connected to the fixture 4 housing through a sliding groove, and the sliding direction is perpendicular to the axial direction of the data cable, that is, perpendicular to the sliding direction of the sliding frame 621.

[0046] Reference Figure 3 and Figure 4 One end of each linkage frame 731 is rotatably connected to the adjustment frame 61 located on the same side of the data cable via a pin, and the other end is rotatably connected to the corresponding abutment frame 72 via a pin, so that when adjusting the distance between the conductive sheets 5, the adjustment frame 61 can drive the abutment frame 72 to slide through the linkage frame 731, thereby changing the end position of the abutment frame 72 to adapt to the diameter of the data cable.

[0047] Reference Figure 3 and Figure 4 Each gripper 71 is rotatably connected to the corresponding fixture 4 housing via a pin at the end away from the corresponding abutment 72, and the rotation axis is vertically set. The data line on each fixture 4 housing is located on the rotation path of the end of the corresponding gripper 71 close to the abutment 72, so that after the gripper 71 rotates, it can abut against the side wall of the data line together with the abutment 72, causing the data line to bend to a certain extent, thereby clamping and fixing the data line, reducing the probability of the data line coming out. When clamped, the gripper 71 is perpendicular to the data line, so that the gripper 71 self-locks by the friction between the data lines.

[0048] Reference Figure 3 and Figure 4 When it is necessary to measure data cables of different diameters, loosen the locking screw 6231 and push the locking screw 6231 to slide, thereby causing the locking screw 6231 to drive the corresponding sliding frame 621 to slide. The sliding frame 621 drives the corresponding adjusting frame 61 to rotate through the transmission frame 622, thereby causing one side of the conductive sheet 5 to move together with the adjusting frame 61, thus changing the distance between the ends of the conductive sheets 5. This allows for adjustment of the distance between the conductive sheets 5, thus accommodating data cables of different diameters, so that when the data cable is inserted between the conductive sheets 5, it can be tightly pressed against the conductive sheets 5.

[0049] Reference Figure 3 and Figure 4 During this process, the adjustment rack drives the corresponding abutment frame 72 to slide through the linkage frame 731, thereby adjusting the distance between the corresponding clamping frame 71 and the rotating connection end, thus changing the distance between the rear end of the clamping frame 71 and the abutment frame 72, adapting to data cables of different diameters, and reducing the probability of unstable clamping or excessive clamping force on the data cable.

[0050] The implementation principle of the data cable electrical performance testing system in this application embodiment is as follows: During use, the touch screen displays a visual operation interface provided by a graphical user interface application. Operators can select the corresponding data cable model from the drop-down list in the product model selection area, and then select the corresponding test item from the checkboxes in the test item configuration area. Subsequently, the parameter setting area dynamically displays input boxes for relevant parameters. After the operator selects or inputs the corresponding parameters, the industrial control computer calls the corresponding test sequence script from the SQLite relational database, feeds it back to the testing equipment, and enables the testing equipment 1 to set its own parameters based on the received information, thereby adapting to the corresponding test items for different specifications of data cables, and thus enabling the testing equipment 1 to test the data cable.

[0051] Subsequently, the testing device 1 feeds back the detected data (such as continuity resistance, insulation resistance, test signals, etc.) to the industrial control computer, which receives the feedback data. Then, the data comparison unit 32 within the industrial control computer compares the data detected by the testing device 1 with the standardized data and controls the touchscreen display to show the pass / fail conclusion (specifically, the text "Pass") on the testing information display area. The data processing unit 33 processes and analyzes the data detected by the testing device 1 and controls the human-machine interface module 2 to draw scatter plots (function graphs or correspondence graphs), curves, or tables on the testing information display area. For example, impedance curves and other graphical data can be displayed in a two-dimensional coordinate system chart on the testing information display area for easy access by staff.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
