The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description, claims, and drawings. Attached Figure Description

[0022] The following detailed description of the embodiments of this utility model, in conjunction with the accompanying drawings, will provide a thorough understanding of how this utility model uses technical means to solve technical problems and achieve technical effects, enabling its implementation. It should be noted that, provided there is no conflict, the various embodiments and features within them can be combined with each other, and all resulting technical solutions are within the protection scope of this utility model.
[0023] Furthermore, the steps illustrated in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than that shown here.
[0024] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments. Unless the context clearly indicates otherwise, the singular forms “a” and “an” as used herein are also intended to include the plural. It should also be understood that the terms “comprising” and / or “including” as used herein specify the presence of the stated features, integers, steps, operations, units, and / or components, without excluding the presence or addition of one or more other features, integers, steps, operations, units, components, and / or combinations thereof.
[0025] In actual testing, there are often various core combination methods for testing multi-core cables, with each combination serving as the test case. These core combination methods include at least: testing each single core individually as the test case, and various dual-core combinations formed by randomly selecting two cores from the multi-core cable. Specifically, when using a combination of two cores as the test case, the first ends of the two cores are connected, and the second ends of the two cores are used as the two test terminals of the current test case.
[0026] Therefore, for multi-core cables, the core combination method n satisfies the following expression: n = m + C m 2 Where m represents the number of cable cores. It should be noted that the mapping relationship between the number of cable cores in a multi-core cable and the number of cable core combinations used as the test component can also satisfy other reasonable relationships. This invention does not impose specific limitations on this, and those skilled in the art can set the mapping relationship according to actual needs.
[0027] Figure 1 This is a schematic diagram of the overall structure of the cable testing system according to an embodiment of this application. Figure 1 As shown, the cable testing system described in this embodiment of the present invention includes: a testing tool A, a route testing instrument B, and a cable under test C connected in sequence.
[0028] like Figure 1 As shown, test tool A is connected to routing instrument B, which in turn is connected to the cable under test, C. Routing instrument B is used to generate a line configuration scheme based on timing information and the number of cable cores. It then controls the on / off state of instrument B according to the current line configuration scheme, enabling the test tool to perform corresponding tests on the cable under test, C, when the instrument is on.
[0029] In one embodiment, the routing instrument B further includes a first button and a second button. The first button is used to input timing information. The second button is used to input cable core quantity information.
[0030] In practical applications, the multi-core cable under test will be configured in various ways depending on the number of cores. The test component formed by each combination of cores is called the cable under test (C). In other words, when testing a multi-core cable, it is necessary to perform corresponding tests on the cable under test (C) for each combination, and the number of tests is matched with the number of core combinations.
[0031] Furthermore, the routing instrument B includes a logic controller B1 and a relay assembly B2. The relay assembly B2 consists of multiple relays. The input terminal of the relay assembly B2 is connected to the test tool A, the output terminal of the relay assembly B2 is connected to the cable under test C, and the control terminal of each relay in the relay assembly B2 is connected to the logic controller B1.
[0032] Relay assembly B2 is used to control multiple relays in the relay assembly to achieve on / off control between relays in a corresponding specified series-parallel combination manner through the following control instructions, so that relay assembly B2 forms a corresponding conducting circuit or breaking circuit under the control of the validity of the drive signal in different test cycles.
[0033] Thus, when relay assembly B2 is configured as a conducting circuit, it establishes an electrical connection between the test tool A and the cable under test C, allowing testing of the cable under test C to proceed. Conversely, when relay assembly B2 is configured as a disconnecting circuit, it breaks the electrical connection between the test tool A and the cable under test C, preventing testing of the cable under test C from being performed.
[0034] Furthermore, logic controller B1 generates a line configuration scheme based on the input timing information and the number of cable cores. Relay component B2, under the control commands in the line configuration scheme, forms a corresponding conducting circuit for the valid signal interval in each test cycle and a corresponding disconnecting circuit for the invalid signal interval.
[0035] In this embodiment of the invention, the line configuration scheme includes: a test signal timing sequence formed by multiple test cycles, and control instructions for configuring the line using relay components corresponding to each test cycle. The number of cable core combinations for a multi-core cable matches (is the same as) the number of test cycles.
[0036] Each test cycle in the test signal timing sequence is formed as follows: a valid signal interval for indicating instrument on and an invalid signal interval for indicating instrument off. In one embodiment, the valid signal interval may be represented by a high-level signal, and the invalid signal interval may be represented by a low-level signal.
[0037] In embodiments of the present invention, such as Figure 2 As shown, a test cycle is the total time required to perform one test on a cable C under test. The time occupied by a unit test cycle includes: a valid signal interval and at least one invalid signal interval. The input timing information is the instrument conduction time in the test cycle corresponding to each cable core combination, i.e., the total time occupied by the valid signal interval.
[0038] In this way, after the logic controller B1 obtains the input timing information and the number of cable cores, it first determines the number of test cycles required for the current multi-core cable based on the pre-set mapping and matching relationship between the number of cable cores and the cable core combination method, and generates the test signal timing sequence based on the timing information.
[0039] Furthermore, to ensure efficient and smooth switching between the valid and invalid signal regions of adjacent test cycles, in this embodiment of the invention, as different test cycles progress in the test signal timing sequence, each test cycle at different stages corresponds to a specified series-parallel combination of relays. In other words, in the test signal timing sequence, the valid signal intervals at different time stages correspond to specified relay combinations.
[0040] In this way, after generating the test signal sequence, logic controller B1 can immediately and directly invoke the specified relay combination control instruction corresponding to each test cycle according to the timing process of the test cycle (without needing to calculate the specified relay combination control instruction). At this time, relay component B2 forms the corresponding relay component configuration circuit under the control of the specified relay combination control instruction, so that relay component B2, under the control of the specified relay combination control instruction, controls the on / off state of the specified relay to enable relay component B2 to complete the on / off control between test tool A and the cable under test C in the corresponding timing sequence.
[0041] Furthermore, the cable testing system described in this embodiment of the invention also includes a measurement result recorder. The measurement result recorder is used to record the test results of the cable C under test. After the testing tool A completes the test on the multi-core cable, the measurement result recorder can automatically obtain the test results of all the tested cables C within the multi-core cable.
[0042] In this embodiment of the invention, the measurement result recorder is implemented using an image acquisition device. The acquisition unit of the image acquisition device is aligned with the display screen in the test tool A.
[0043] In one embodiment, test tool A is an insulation resistance tester. In this case, test tool A can perform corresponding insulation resistance tests on each cable C under test. The insulation resistance tester can apply high voltage between the two cores to detect the insulation withstand capability of the cable C under test.
[0044] In another embodiment, the testing tool A is a continuity tester. In this case, testing tool A can perform a corresponding continuity test on each cable C under test. The continuity tester can measure the resistance between the two ends of the cable to ensure fault-free continuity, thereby determining whether there are damaged wires in cable C.
[0045] This utility model discloses a cable testing system. This testing system can automatically select the control mode corresponding to the cable core combination, reducing manual intervention time, significantly reducing the testing time for multi-core cables, and improving the testing efficiency of multi-core cables.
