[0002] At present, the network status detection of large-capacity cables is usually carried out using large cable test terminals. However, the use of large cable test terminals has the defects of large number of transfer cables, large size, and difficult operation. Take the aviation system as an example. The aviation system has various types of aircraft, and the cable interconnection points on the aircraft range from thousands to tens of thousands. For example, a large aircraft has more than a thousand plugs and 10,000 to 20,000 cable connection points. Dozens of large cable test terminals are required, and all terminals must be connected to the test host, with many connecting wires and transfer lines. The space on the aircraft is limited, and the huge test system connection cables are very likely to cause system failures. As a result, testers spend too much energy troubleshooting test system failures, which seriously affects test efficiency.

[0003] At the same time, when using a large cable test terminal to test the network status of the cable, each cable on the large cable test terminal needs to be tested in turn according to the connection order, which results in a huge testing workload. Summary of the invention

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0044] Figure 1 The flowchart of a method for quickly testing the status of a large-capacity cable network according to an embodiment of the present application is shown. Figure 1 , including the following steps:

[0045] S101: Group a predetermined number of cables.

[0046] In one embodiment, a predetermined number of incoming cables are grouped according to whether there is an association relationship between the cables. The user can define the association relationship according to the cable structure or function. For example, the cable core wire structure of area A is different from that of area B, or the cable in area A is used for power transmission and the cable in area B is used for communication signal transmission, that is, there is no connection between the cables in area A and area B. Then the cables in area A can be grouped into one group and the cables in area B can be grouped into another group.

[0047] Subsequently, only the cable status parameters within the group will be tested, and no testing will be performed between groups.

[0048] S102: Divide the cables in each group into a plurality of test units.

[0049] In one embodiment, dividing the cables in each group into a plurality of test units includes: classifying the cables in the group according to structural features, such as the core structure of the cables, the types of the conductors, etc., and determining the number of cables in each classification. One cable in each classification is assigned to a test unit, and the types of cables in a test unit include all types or some types.

[0050] For each group, the number of test units is equal to the number of cables of the most numerous type.

[0051] In another embodiment, dividing the cables in each group into a plurality of test units includes: classifying the cables in the group according to functional characteristics, such as power transmission cables, electrical signal transmission cables, etc., the power transmission cables can be further classified according to the transmission power, and the electrical signal transmission cables can be classified according to different communication requirements. After the classification requirements are determined, the number of cables of each classification can be determined. One cable of each classification is assigned to a test unit, and the types of cables in a test unit include all types or some types.

[0052] For each group, the number of test units is equal to the number of cables of the largest type.

[0053] S103: Determine a set of connection points to be tested in each test unit according to the test requirements.

[0054] Users can select different cables to perform related tests according to different test requirements. For example, when a continuity test is required, find the cable that needs to be tested in each test unit. If an insulation test is required, find the cable that needs to be tested in each test unit. If a resistance test is required, find the cable that needs to be tested in each test unit.

[0055] S104: For each group, the connection point set in one test unit and the connection point sets in other test units in the group are tested for cable network status parameters respectively.

[0056] After all the cables that meet the test requirements in all the test units in a group are determined, the core wire access points of all the cables that need to be tested constitute a connection point set. The connection point set in each test unit and the connection point set in each other test unit are tested for corresponding cable network status parameters.

[0057] In order to connect the connection point sets between the test units, in one implementation, a test terminal is connected to each test unit, and the number of connection points provided on the test terminal is equal to the number of core wires in the test unit including all types of cables, that is, the test terminal can meet the access requirements of all test units. After the test terminal is connected to the test unit, the number of effective connection points on the test terminal is equal to or less than the number of connection points of the test unit, and the number of effective connection points depends on the number of connection points of the connected test unit. The training points of all test sub-units determined on the test terminal correspond one-to-one to the connection point set to be tested on the test unit.

[0058] In order to clearly mark that each test terminal is used to meet different test requirements, in the scheme of the present application, a test sub-unit is determined on each test terminal, and each test sub-unit can correspond to one or more test requirements, such as one test sub-unit is only used for conductivity test, another test sub-unit is only used for insulation test or resistance test, or one test sub-unit can be used to perform multiple tests, such as the test sub-unit needs to perform conductivity test, insulation test and resistance test in sequence according to time sequence.

[0059] In one group, the test sub-units in one test unit are connected and tested with the test sub-units in other test units one by one, so as to test the cable network status parameters in the test unit and other test units.

[0060] For different groups, the test can be carried out simultaneously according to the test method within the above group, or each group can be tested one by one, or several groups can be tested in batches. This application does not make specific restrictions on the test timing and order between groups, which can be adjusted accordingly according to the test requirements.

[0061] Figure 2 The figure is a diagram showing a distribution mode of cables in a test terminal access group and a distribution mode of test sub-units on each test terminal according to an embodiment of the present application. Figure 2 , a grouped cable is divided into 4 test units, and the 4 test units are respectively connected to a test terminal, namely test terminal 1, test terminal 2, test terminal 3 and test terminal 4.

[0062] The following describes the conduction test as an example.

[0063] Three test sub-units are determined on test terminal 1, two test sub-units are determined on test terminal 2, two test sub-units are determined on test terminal 3, and three test sub-units are determined on test terminal 4. When conducting the test:

[0064] Testing of cables in each test sub-unit in test terminal 1 and cables in each test sub-unit in test terminals 1, 2, 3, 4;

[0065] Testing of cables in each test sub-unit in test terminal 2 and cables in each test sub-unit in test terminals 2, 3, and 4;

[0066] Testing of cables in each test sub-unit in test terminal 3 and cables in each test sub-unit in test terminals 3 and 4;

[0067] Testing of cables in each test sub-unit in the test terminal 4 and testing of cables in each test sub-unit in the test terminal 4 .

[0068] Similarly, resistance testing can also be performed according to the above testing method.

[0069] use Figure 2 The structure shown can also be individually tested for insulation, and the specific method includes: testing the insulation resistance value between any two unconnected wires in any two test sub-units, and the insulation resistance value between any wire and the shell (or shielding layer).

[0070] It should be noted that Figure 2 The structure shown can be subjected to one test alone or multiple tests, such as a continuity test, followed by a resistance test, and then an insulation test.

[0071] Other, Figure 2 The structure shown is only exemplary, and all test units in a group can be connected to the test terminal for testing, or the test units can be divided into batches, and each batch is connected to the test terminal for testing. The selection method is determined according to the number of test units and the actual needs of users.

[0072] In one implementation, the test terminals are connected by wireless communication, which can avoid a large number of connection lines and transfer lines.

[0073] According to the second aspect of the present application, a rapid testing system for the status of a large-capacity cable network is also provided. Figure 3 The schematic diagram of the structure of a fast testing system for a large-capacity cable network state according to an embodiment of the present application is shown. Figure 3 The rapid test system includes a test platform 100 and multiple test terminals 200. The number and type of connection points set in each test terminal 200 are equal to the number and type of core wires contained in the basic cable unit in the cable to be tested. The basic cable unit is: the cables of the cable to be tested are classified, and one cable of each classification is collected into one unit. The unit including all types is the basic cable unit. Each test terminal is provided with a communication device, which enables the test terminal to communicate with other test terminals and the test platform. In a preferred embodiment, the test terminals communicate with each other through a wireless connection.

[0074] Figure 4 FIG. 1 is a schematic diagram of a test terminal according to an embodiment of the present application. Figure 4 The test terminal 200 includes a housing 210, a communication and power board 220 arranged inside the housing, a high-voltage circuit board 230, a main test board 20, a switch matrix board 250, a test port 260 arranged at the top of the housing, and a rod antenna 270. The test port is a 64-core test port, that is, the number of connection points of the test port is 64. Furthermore, a 16-core backup port 280 is also provided at the top of the test terminal to be used for cables with a small number of cores, or used together with the 64-core test port to expand the number of testable cores of the test terminal.

[0075] It can be seen from the above technical solutions that the rapid testing method and testing system for the network status of a large-capacity cable in the present application, by grouping a large number of cables, only tests the network status of the cables in the group, avoids unnecessary testing between cables that have no correlation, and greatly reduces the test volume. Since only the cables in each group are tested, a large number of cables are divided into multiple groups, and the number of cables in each group is reduced exponentially, so the volume of the test terminal is greatly reduced, thereby greatly simplifying the structure of the test system, reducing system failures, and greatly improving test efficiency.

[0076] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
