[0039] The realization, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0040] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] Figure 1 It is a schematic flowchart of an embodiment of the cable identification method of the present invention.

[0042] The cable identification method of this embodiment is applied to a cable identification device. Among them, the cable identification device includes a cable testing device for sending a test signal and analyzing and processing the feedback test signal, and a cable transfer device for connecting the cable to be tested to the test circuit. The structure of the cable identification device is as Figure 2 shown. The cable testing device is electrically connected to the cable transfer device, and the cable to be tested is connected to the cable testing device through the cable transfer device. In a specific embodiment, the circuit structure of the cable identification device is as Figure 3 shown. The cable identification device includes a cable testing device 10 and a cable transfer device 20. The cable testing device 10 includes a cable testing circuit 101 and a test interface 102; the cable transfer device 20 includes a cable connector 202 for connecting the cable to be tested and a test socket 201. Among them, the cable testing circuit 101 can be a microprocessor such as a single-chip microcomputer, a DSP or an FPGA, which is not limited here. The cable connector 202 is used to connect the cable to be tested to the cable testing circuit 101, that is, to connect the cable to be tested to the test circuit. The test socket 201 is adapted to the test interface 102. When the test socket 201 is inserted into the test interface 102, the cable to be tested is connected to the cable testing circuit 101, and the cable testing circuit 101 can test the cable to be tested.

[0043] Specifically, referring to Figure 1 , the cable identification method includes:

[0044] Step S10: The cable testing device sends a first test signal to the cable transfer device and receives the first test signal fed back by the cable transfer device;

[0045] The first test signal may be a PRBS (pseudo-random code), which is a pseudo-random sequence containing 0 and 1. The cable test device 10 is connected to a main control circuit, such as a processor such as a single-chip microcomputer, DSP or FPGA, and the cable test device 10 performs a test operation according to the control instruction of the main control circuit. During the test process, the cable test device 10 sends a first test signal, that is, sends a PRBS signal to the cable to be tested connected to the cable switching device 20, and the cable to be tested then feeds back the first test signal to the cable test device 10 via the cable switching device 20. It can be understood that the cable switching device 20 can have multiple test channels built in to allow multiple cables to be tested simultaneously.

[0046] Step S20: determining whether the bit error rate of the first test signal fed back is within a preset bit error rate range;

[0047] The first bit error rate range is used to determine the deviation rate between the first test signal fed back and the first test signal sent. For example, it is assumed that there are 5 cables to be tested, which are placed in five test channels respectively. The cable test device 10 sends a first test signal of 0 to the cable in the first test channel, and the first test signal fed back by the cable in the first test channel is also 0; the cable test device 10 sends a first test signal of 1 to the cable in the second test channel, and the first test signal fed back by the cable in the second test channel is also 1; the cable test device 10 sends a first test signal of 0 to the cable in the third test channel, and the first test signal fed back by the cable in the third test channel is also 0; the cable test device 10 sends a first test signal of 1 to the cable in the fourth test channel, and the first test signal fed back by the cable in the fourth test channel is also 1; the cable test device 10 sends a first test signal of 0 to the cable in the fifth test channel, and the first test signal fed back by the cable to be tested in the fifth test channel is also 0; then it means that the bit error rate of the first test signal sent to the cable to be tested is 0. In this embodiment, when the bit error rate of the first test signal is within the preset bit error rate range, the next test operation is performed. In order to ensure the quality of the cable, the preset bit error rate range can be set to 0, that is, when the bit error rate of the first test signal fed back by the cable adapter 20 received by the cable testing device 10 is 0, the next test operation is performed.

[0048] Step S30: when the bit error rate of the fed-back first test signal is within a preset bit error rate range, obtaining a number of second test signals corresponding to the number of cables to be tested;

[0049] The second test signal can be a PRBS (pseudo-random code). The number of second test signals corresponding to each cable under test can be determined through a pre-set mapping table. For example, a mapping table can be established between the identification information of the cables under test and the second test signals, or a mapping table can be established between the test channels where the cables under test are located and the second test signals. There is no limitation here.

[0050] Optionally, in one embodiment, step S30 includes:

[0051] Step S301: When the bit error rate of the fed-back first test signal is within a preset bit error rate range, determine the identification information of the cable under test;

[0052] Step S302: Obtain the corresponding number of second test signals according to the identification information of the cable under test.

[0053] The identification information of the cable under test is used to distinguish the cables under test in each test channel. A mapping table can be established in advance between the cables under test and the second test signals, and the number of second test signals corresponding thereto can be determined by looking up the table according to the identification information of the cable under test.

[0054] Optionally, in one embodiment, step S302 includes:

[0055] Step S3021: Determine the test channel where the cable under test is located according to the identification signal of the cable under test;

[0056] Step S3022: Obtain the corresponding number of second test signals for the test channel where the cable under test is located.

[0057] In this embodiment, the number of second test signals corresponding thereto can be determined based on the mapping table between the test channel where the cable under test is located and the second test signals. That is, first determine the test channel where the cable under test is located according to the identification signal of the cable under test, and then determine the number of second test signals corresponding to the test channel where the cable under test is located by looking up the table.

[0058] Further, in one embodiment, after step S30, it further includes:

[0059] Step S70: When the bit error rate of the fed-back first test signal exceeds the preset bit error rate range, determine that the cable under test is unqualified.

[0060] When there is a deviation between the first test signal sent to the cable under test and the first test signal fed back by the cable under test, that is, the bit error rate of the fed-back first test signal exceeds the set preset bit error rate range, it indicates that the wire sequence of the cable under test is incorrect, and there may be a case of cross soldering in the cable under test. For example, if the cable testing device 10 sends a pseudo-random code of 0, but the pseudo-random code fed back by the cable in the first test channel is 1, it means that a bit error has occurred. In this case, it can be determined that the wire sequence of the cable under test is incorrect, and the cable under test is a non-conforming product.

[0061] Step S40: Send the second test signals corresponding to the number of the cables under test to the cable transfer device and receive the second test signals fed back by the cable transfer device;

[0062] The cable testing device 10 sequentially sends the corresponding number of second test signals to the cables under test in each test channel and receives the corresponding number of second test signals fed back by the cables under test in each test channel. For example, for the cable under test in the first test channel, the cable testing device 10 sends 1 + m second test signals; for the cable under test in the second test channel, the cable testing device 10 sends 2 + m second test signals; for the cable under test in the third test channel, the cable testing device 10 sends 3 + m second test signals... where m is an integer.

[0063] Step S50: Determine whether the number of the fed-back second test signals is consistent with the number of the sent second test signals;

[0064] The cable testing device 10 compares the number of the second test signals sent to each cable under test with the number of the second test signals fed back by each cable under test, so as to determine whether the wire sequence of the cable under test is correct and whether it is a qualified cable.

[0065] Step S60: When the number of the fed-back second test signals is consistent with the number of the sent second test signals, determine that the cable under test is qualified.

[0066] If the number of the second test signals sent by the cable testing device 10 to the cable under test is consistent with the number of the second test signals fed back by the cable under test, it means that the wire sequence of the cable under test is correct, there is no case of cross soldering in the cable under test, and the cable under test is qualified. For example, for the cable under test in the first test channel, the cable testing device 10 sends 1 + m second test signals, and the number of the second test signals fed back by the cable under test in the first test channel is 1 + m, then the cable under test in the first test channel is qualified; for the cable under test in the second test channel, the cable testing device 10 sends 2 + m second test signals, and the number of the second test signals fed back by the cable under test in the second test channel is 2 + m, then the cable under test in the second test channel is qualified.

[0067] Further, after step S60, it further includes:

[0068] Step S80: When the number of the second test signals fed back is inconsistent with the number of the second test signals sent, determine that the cable under test is unqualified.

[0069] If the number of the second test signals sent by the cable testing device 10 to the cable under test is inconsistent with the number of the second test signals fed back by the cable under test, it indicates that the cable sequence of the cable under test is incorrect, and there may be a case of cross soldering in the cable under test. At this time, it is determined that the cable under test is unqualified. For example, for the cable under test in the first test channel, the cable testing device 10 sends 1 + m second test signals, and the number of the second test signals fed back by the cable under test in the first test channel is 1 + m, then the cable under test in the first test channel is qualified; for the cable under test in the second test channel, the cable testing device 10 sends 2 + m second test signals, and the number of the second test signals fed back by the cable under test in the second test channel is 2 + m, then the cable under test in the second test channel is qualified; for the cable under test in the third test channel, the cable testing device 10 sends 3 + m second test signals, and the number of the second test signals fed back by the cable under test in the third test channel is m, then the cable under test in the third test channel is unqualified.

[0070] In summary, the present invention first determines whether the bit error rate of the first test signal fed back by the cable under test is within the preset bit error rate range. If it is within the preset bit error rate range, it further determines whether the number of the second test signals sent to the cable under test is consistent with the number of the second test signals fed back by the cable under test. If they are consistent, it indicates that the cable sequence of the cable under test is correct, there is no case of cross soldering in the cable under test, and the cable under test is a qualified product. With such a setting, the cable sequence can be quickly identified, unqualified cables can be screened out, and the production quality of the cables can be improved.

[0071] Optionally, in an embodiment, after the step of sending the second test signals corresponding to the cable under test to the cable transfer device and receiving the second test signals fed back by the cable transfer device, it further includes:

[0072] Step S90: Send the first test signal and the second test signal fed back by the cable transfer device to the main control circuit for the main control circuit to generate a test report of the cable under test.

[0073] In one embodiment, after receiving the first test signal and the second test signal fed back by the cable to be tested, the cable testing device 10 analyzes and processes the fed back first test signal and the second test signal and sends them to the main control circuit, so that the main control circuit can generate a test report based on the cable to be tested, for example, a test report involving the signal transmission rate, line sequence, and abnormal state analysis of the cable to be tested. Furthermore, the main control circuit can upload the test report of the cable to be tested to the host computer to realize visual testing of the cable; it can also upload the test data of the cable to be tested to the server, so that the server can realize data management.
