Description

Technical Field

[0001] This invention relates to the field of cable core technology, and more particularly to an intelligent secondary cable core method and apparatus. Background Technology

[0002] During the maintenance of secondary equipment, extensive wiring verification is required. A cable is typically composed of several or several groups of conductors (each group containing at least two conductors) twisted together; each group of conductors is insulated from each other; the entire cable is covered with a copper foil shielding layer (this shielding layer prevents electromagnetic interference, and at the cable's start and end points, a yellow-green wire is connected to it to form a ground wire (insulated from the internal conductors)); outside the shielding layer is a highly insulated covering layer. A cable is laid between point A and point B, containing several conductors. Therefore, cable wiring verification not only requires checking the one-to-one correspondence of the internal conductors at both ends of the cable, but also requires using specific circuit numbers to distinguish the internal conductors within the same cable.

[0003] Traditional methods of secondary cable verification require the use of multimeters, test lights, and communication devices to check wire numbers and verify core wires. These methods can only verify one or two cores at a time, resulting in a large workload, complex process, and difficulty in detecting errors in wire numbering and mismatches between wire numbers and cable cores.

[0004] In addition, existing solutions have proposed automatic cross-connection based on microcontroller-based multi-frequency pulse or encoding / decoding methods. However, such solutions require manual provision of a common line to form a loop for cross-connection, or they only find the corresponding positional relationship between the cable numbers at both ends, failing to solve the problems of incorrect numbering and confusion between the number header and the cable core. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an intelligent secondary cable cross-connection method and device, which simplifies the cross-connection process and effectively eliminates the phenomenon of incorrect serial numbering and confusion between serial number heads and cable cores.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A method for intelligent secondary cable core bonding includes the following steps:

[0008] S1. Obtain the cable number, and determine the target cable and its information in a preset cable information database based on the cable number. The preset cable information database includes a list of power distribution cables and a standard header document.

[0009] S2. The control core line host sends a core line carrier signal to the core line slave through the target cable. One end of each cell of the target cable is electrically connected to the master port of the core line host, and the other end of each cell is electrically connected to the slave port of the core line slave.

[0010] S3. Control the core line host to obtain the reception result of the core line slave and the response result received by the master port, and determine the circuit number of the cell corresponding to each master port and the slave port based on the reception result, the response result and the standard header document.

[0011] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows:

[0012] A smart secondary cable core line device includes a remote control unit, a core line host, and a core line slave unit;

[0013] The remote control unit is communicatively connected to the core line host and the core line slave respectively. The core line host is provided with a master port, and the core line slave is provided with a slave port that corresponds one-to-one with the master port.

[0014] The core line host is used to execute the above-described intelligent secondary cable core line device.

[0015] The beneficial effects of this invention are as follows: It provides an intelligent secondary cable cross-connection method and apparatus. By establishing a preset cable information database containing a list of distribution cables and standard header documents, the target cable can be quickly identified based on the cable number and relevant information including the loop number of the target cable can be obtained. Based on this, the cross-connection host and cross-connection slave are controlled to perform cross-connection on the target cable by transmitting cross-connection carrier signals, which simplifies the cross-connection process. It can not only detect the continuity of the target cable, but also match each core of the loop number, effectively eliminating the phenomenon of incorrect serial number and confusion between the header and the cable core.

[0025] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please refer to Figure 1 A method for intelligent secondary cable core bonding includes the following steps:

[0027] S1. Obtain the cable number, and determine the target cable and its information in the preset cable information database based on the cable number. The preset cable information database includes a list of power distribution cables and a standard header document.

[0028] S2. The core line host 1 sends a core line carrier signal to the core line slave 2 through the target cable. One end of each cell of the target cable is electrically connected to the master port 11 of the core line host 1, and the other end of each cell is electrically connected to the slave port 21 of the core line slave 2.

[0029] S3. Control the core line host 1 to obtain the reception result of the core line slave 2 and the response result received by the master port 11. Based on the reception result, the response result and the standard header document, determine the circuit number of the cell corresponding to each master port 11 and slave port 21.

[0030] As can be seen from the above description, the beneficial effects of the present invention are as follows: by establishing a preset cable information database containing a list of power distribution cables and standard header documents, the target cable can be quickly determined based on the cable number and relevant information including the loop number of the target cable can be obtained. Based on this, the core line host 1 and the core line slave 2 are controlled to perform core line verification on the target cable by transmitting core line carrier signals, which simplifies the core line verification process. It can not only detect the continuity of the target cable, but also match each core of the loop number, effectively eliminating the phenomenon of incorrect serial number and confusion between the header and the cable core.

[0031] Further, step S2 includes:

[0032] The core line host 1 is controlled to send different core line carrier signals from each master port 11 to the slave port 21 of the core line host 1 in sequence.

[0033] As can be seen from the above description, during core line operation, the core line host 1 outputs different core line carrier signals to different master ports 11 at different time points, so as to distinguish the transmission and reception status of different master ports 11 and slave ports 21 and improve the accuracy of core line operation.

[0034] Further, step S3 specifically includes:

[0035] S31. Control the core line host 1 to establish the correspondence between the main port 11 and the circuit number of the battery cell of the target cable according to the cable information;

[0036] S32. If each master port 11 of the core line host 1 receives an acknowledgment signal or each slave port 21 of the core line slave 2 receives the corresponding core line carrier signal, then the circuit number of the cell corresponding to the slave port 21 is determined according to the correspondence and the reception result.

[0037] As described above, after receiving the core line carrier signal, each slave device 2 sends an acknowledgment signal on the same communication line. By analyzing the acknowledgment signal received by the master device 1 or the reception result of the slave device 2, it can be determined whether all the cells of the target cable are in a conductive state. If each master port 11 of the master device 1 does not receive an acknowledgment signal, or each slave port 21 of the slave device 2 does not receive the corresponding core line carrier signal, then the cable is considered to be in an abnormal state (short circuit or broken circuit). Both the master and slave devices will display a cable abnormality, and a ground wire should be connected to the grounding port.

[0038] Furthermore, step S32 also includes:

[0039] Provided that the host grounding port 16 does not receive any response signal and the slave grounding port 26 does not receive any carrier signal, if the host port 11 does not receive the response signal or the slave port 21 does not receive the core line carrier signal, then the corresponding cell of the host port 11 or the slave port 21 is marked as disconnected.

[0040] As can be seen from the above description, during the core line process, it is also possible to detect whether there is a fault in the target cable's battery cell. Under the premise that the host grounding port 16 does not receive any response signal and the slave grounding port 26 does not receive any carrier signal, if the core line carrier signal or response signal does not arrive as expected, it can be considered that the battery cell corresponding to the host port 11 or slave port 21 has been disconnected.

[0041] Furthermore, step S32 also includes:

[0042] Provided that the host grounding port 16 does not receive any response signal and the slave grounding port 26 does not receive any carrier signal, if the host port 11 receives at least two of the response signals or the slave port 21 receives at least two of the core carrier signals, then the corresponding cells of the host port 11 and the slave port 21 are identified as having a short circuit between the cores.

[0043] If the host grounding port 16 receives any response signal or the slave grounding port 26 receives any carrier signal, and the master port 11 does not receive a response signal or the slave port 21 does not receive the core line carrier signal, then the corresponding cell of the master port 11 and the slave port 21 is identified as short-circuited to ground.

[0044] As described above, during the core circuit fabrication process, assuming that the master ground port 16 does not receive any acknowledgment signal and the slave ground port 26 does not receive any carrier signal, if the master port 11 or slave port 21 receives different signals with the same function, it indicates a cell short circuit, which is marked as the core circuit fabrication result. Conversely, if the master ground port 16 receives any acknowledgment signal or the slave ground port 26 receives any carrier signal and the master port 11 or slave port 21 receives different signals with the same function, it indicates a cell short circuit to ground, which is marked as the core circuit fabrication result.

[0045] Furthermore, the procedure before step S2 includes:

[0046] The core line host 1 and the core line slave 2 are controlled respectively to complete the wiring confirmation.

[0047] As can be seen from the above description, before sending the core line carrier signal, the wiring is confirmed to ensure that the core line host 1 and the core line slave 2 are connected to the target cable, and that the master port 11 and the corresponding slave port 21 are connected to the same battery cell.

[0048] Further, step S1 includes:

[0049] The target cable and its cable information are displayed on the screens of the core line host 1 and the core line slave 2, respectively.

[0050] As can be seen from the above description, displaying the target cable and cable information on the screen can help on-site cable verification personnel quickly complete wiring and information verification.

[0051] Please refer to Figures 2 to 5A smart secondary cable core-layout device includes a remote control unit, a core-layout host 1, and a core-layout slave 2. The remote control unit is communicatively connected to the core-layout host 1 and the core-layout slave 2. The core-layout host 1 is provided with a master port 11, and the core-layout slave 2 is provided with slave ports 21 corresponding to the master ports 11. The core-layout host 1 is used to execute the above-described smart secondary cable core-layout device.

[0052] As can be seen from the above description, the beneficial effects of the present invention are as follows: by establishing a preset cable information database containing a list of power distribution cables and standard header documents, the target cable can be quickly determined based on the cable number and relevant information including the loop number of the target cable can be obtained. Based on this, the core line host 1 and the core line slave 2 are controlled to perform core line verification on the target cable by transmitting core line carrier signals, which simplifies the core line verification process. It can not only detect the continuity of the target cable, but also match each core of the loop number, effectively eliminating the phenomenon of incorrect serial number and confusion between the header and the cable core.

[0053] Furthermore, the core line host 1 includes a first remote communication module 12, a first main control module 13, a first display screen 14, and a signal transmission module 15;

[0054] The slave unit 2 of the core line includes a second remote communication module 22, a second main control module 23, a second display screen 24, and a signal receiving module 25;

[0055] The first main control module 13 is electrically connected to the first remote communication module 12, the first display screen 14 and the signal transmission module 15 respectively, and the signal transmission module 15 is electrically connected to all the main ports 11 respectively.

[0056] The second main control module 23 is electrically connected to the second remote communication module 22, the second display screen 24 and the signal receiving module 25 respectively, and the signal receiving module 25 is electrically connected to all the slave ports 21 respectively;

[0057] The first main control module 13 is connected to the remote control unit and the second remote communication module 22 through the first remote communication module 12, and the second main control module 23 is connected to the remote control unit through the second remote communication module 22.

[0058] As can be seen from the above description, both the core line host 1 and the core line slave 2 are equipped with display screens to provide real-time feedback on cable information and core line results. They adopt a modular design and can be used remotely.

[0059] Furthermore, both the core line host 1 and the core line slave 2 are equipped with independent power supplies 3.

[0060] As can be seen from the above description, the inclusion of an independent power supply 3 can expand the application range of the core line device and make it easier to carry.

[0061] Please refer to Figure 1 Embodiment 1 of the present invention is as follows:

[0062] A method for intelligent secondary cable core bonding includes the following steps:

[0063] S1. Obtain the cable number and determine the target cable and its information in the preset cable information database based on the cable number. The preset cable information database includes a list of power distribution cables and standard header documents.

[0064] In this embodiment, the details of a cable include its serial number, the starting and ending points of its installation, the number of conductors inside the cable (commonly referred to as the number of cores), and the loop number of the conductors inside the cable. This information is usually scattered in the power distribution cable register and standard header documents. See Tables 1 and 2 for details:

[0065] Table 1 List of Power Distribution Cables

[0066]

[0067] Table 2 Standard Header Documents

[0068]

[0069] Taking cable number 7FD105 as an example, the system quickly retrieves the cable's loop number, specifications, start point, and end point from the preset cable information database. This information is then packaged and sent to the core line host 1 and core line slave 2. The displays on the core line host 1 and core line slave 2 show: the core line cable name is 7FD105, the start point is the LCU7-A0 cabinet of Unit 7 near the generator, the end point is the speed controller electrical cabinet of Unit 7, and the cable specification is 4*2.5. After seeing this information, personnel on site can quickly locate the laying location of the target cable, preventing them from going to the wrong bay. Furthermore, if the preset cable information database cannot find the cable number corresponding to it, the information can be transmitted manually.

[0070] S2. The core line host 1 sends a core line carrier signal to the core line slave 2 through the target cable. One end of each cell of the target cable is electrically connected to the main port 11 of the core line host 1, and the other end of each cell is electrically connected to the slave port 21 of the core line slave 2.

[0071] In this embodiment, before sending the core line carrier signal, both the core line host 1 and the core line slave 2 are controlled to complete the wiring confirmation. The wiring confirmation process is performed manually, for example:

[0072] Taking cable number 7FD105 as an example, the target core line cable contains 4 wires. The operator connects the external terminals 1-4 of the main transmitter to one end of the 7FD105 cable. After pressing the confirmation button on the screen, the core line cable information disappears. Similarly, the operator connects the external terminals 1-4 of the slave transmitter to the other end of the 7FD105 cable and presses the confirmation button on the screen. The core line cable information disappears again. This is done to ensure that the core line host 1 and the core line slave 2 are connected to the target cable. Then, the control core line host 1 sequentially sends different core line carrier signals from each master port 11 to the slave port 21 of the core line host 1.

[0073] S3. Control the core line host 1 to obtain the reception result of the core line slave 2 and the response result received by the master port 11. Based on the reception result, response result and standard number header document, determine the circuit number of the cell corresponding to each master port 11 and slave port 21.

[0074] In this embodiment, step S3 specifically includes:

[0075] S31. The control core line host 1 establishes the correspondence between the main port 11 and the circuit number of the battery cell of the target cable based on the cable information.

[0076] S32. If each master port 11 of the core line host 1 receives an acknowledgment signal or each slave port 21 of the core line slave 2 receives the corresponding core line carrier signal, then the circuit number of the cell corresponding to the slave port 21 is determined according to the correspondence and the reception result.

[0077] Taking cable number 7FD105 as an example, when the core line carrier signals received by each slave port 21 of core line slave 2 correspond one-to-one with the signals emitted by the master port 11, it indicates that the battery cells of the target cable are all normally connected. Then, core line master 1 and core line slave 2 respectively display the circuit number of their respective ports and the connected battery cells, as shown below:

[0078] Table 3. Main Port and its Corresponding Cell Circuit Number

[0079] 1 2 3 4 JA102 JA103 JU203 JU204

[0080] Table 4. Circuit numbers from the port and its corresponding cell

[0081] 1 2 3 4 JU203 JA102 JU204 JA103

[0082] Furthermore, if the core line carrier signals received by each slave port 21 of the core line slave 2 do not correspond one-to-one with the signals emitted by the master port 11, it indicates that the cable is faulty. The master and slave screens will then display the message "The cable is faulty; further judgment requires grounding." Connect the master grounding port 16 and the slave grounding port 26 to the ground wire and click OK.

[0083] The condition is that the host grounding port 16 has not received any acknowledgment signal and the slave grounding port 26 has not received any carrier signal. If the host port 11 has not received an acknowledgment signal or the slave port 21 has not received a core line carrier signal, then the corresponding cell of the host port 11 or slave port 21 is marked as disconnected. For example, when the host port has not received any acknowledgment signal and the slave grounding port has not received any carrier signal, when port 11 of the host port has not received an acknowledgment signal from the core line host 1, or port 21 of the slave port has not received a core line carrier signal from the core line slave 2, then disconnection can be entered in the table for port 11 of the host port and port 21 of the slave port.

[0084] If, under the premise that the master grounding port 16 does not receive any acknowledgment signal and the slave grounding port 26 does not receive any carrier signal, at least two acknowledgment signals are received by the master port 11 or at least two core line carrier signals are received by the slave port 21, then the corresponding cores of the master port 11 and slave port 21 are marked as short-circuited. For example, if the master grounding port 16 does not receive any acknowledgment signal and the slave grounding port 26 does not receive any carrier signal, and the master port 11 receives feedback signals from both the slave port 21 and slave port 3, and the slave port 21 of the core line slave 2 receives core line carrier signals from the master port 11 and master port 4 of the core line master 1, then a short circuit between cores is entered in the tables for the 1st and 4th ports on the display screen of the core line master 1, and a short circuit between cores is entered in the tables for the 2nd and 3rd ports on the display screen of the core line slave 2.

[0085] The host grounding port 16 receives any acknowledgment signal or the slave grounding port 26 receives any carrier signal.

[0086] If the master port 11 does not receive an acknowledgment signal or the slave port 21 does not receive the core line carrier signal, then the corresponding master port 11 and slave port 21 are marked as short-circuited to ground. For example, when the master port 11 does not receive any acknowledgment signal and the slave ground port does not receive any carrier signal, when the master port 11 does not receive an acknowledgment signal from the core line host 1, or the slave port 21 does not receive the core line carrier signal from the core line slave 2, then a core-to-ground short circuit can be entered in the table for the master port 11 and the slave port 21.

[0087] Please refer to Figures 2 to 5 Embodiment two of the present invention is as follows:

[0088] A smart secondary cable core line device includes a remote control unit, a core line host 1, and a core line slave 2;

The second master control module 23 is electrically connected to the second remote communication module 22, the second display screen 24, and the signal receiving module 25, respectively, and the signal receiving module 25 is electrically connected to all slave ports 21. The first master control module 13 communicates with the remote control unit and the second remote communication module 22 through the first remote communication module 12, and the second master control module 23 communicates with the remote control unit through the second remote communication module 22. Furthermore, both the core line host 1 and the core line slave 2 are equipped with independent power supplies 3.

[0091] Among them, the first remote communication module 12 and the second remote communication module 22 can be Bluetooth communication, and the remote control unit sends cable information to the core line host 1 and the core line slave 2 via Bluetooth.

[0092] In summary, the intelligent secondary cable cross-connection method and apparatus provided by this invention establishes a preset cable information database containing a list of distribution cables and standard header documents. Based on the cable number, the target cable can be quickly identified and relevant information, including the loop number of the target cable, obtained. Based on this, the cross-connection host and slave devices are controlled to perform cross-connection on the target cable by transmitting cross-connection carrier signals, simplifying the cross-connection process. This not only detects the continuity of the target cable but also maps the loop number to each cable core, effectively eliminating errors in serial number matching and confusion between header and cable core correspondence.
