[0019] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such use is interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the term "including" and its variants are to be interpreted as open-ended terms meaning "including but not limited to".

[0021] As described in the background technology, during the repair and splicing of optical cables, due to errors in line construction connection, incorrect terminal labeling in the computer room, line splicing and connection errors during repair, the optical fiber may have problems such as fiber sequence and tube sequence misalignment and crossing, which will affect the opening of the optical path.

[0022] Currently, maintenance personnel can only rely on optical time-domain reflectometers (OTDRs) or optical power meters to detect each fiber in a large number of optical fibers to troubleshoot broken fibers, which seriously affects the opening of optical paths and the timeliness of service commissioning.

[0023] Based on this, the present invention proposes a method for troubleshooting broken optical fibers in power optical cables, wherein a sending end device sends lasers with different pulse widths according to the optical fiber serial number at the sending end device, and a receiving end device receives lasers with different pulse widths according to the optical fiber serial number at the receiving end device, and compares the correspondence between the optical fiber serial number at the sending end and the lasers with different pulse widths, so as to determine that the optical fiber serial number at the sending end corresponds to the optical fiber serial number at the receiving end. Therefore, when an optical fiber is broken, the broken optical fiber can be accurately confirmed at the sending end and the receiving end, so as to perform repairs in time, thereby improving the inspection time and operation efficiency.

[0024] The present application is described in detail below through specific embodiments.

[0025] Figure 1 A system for checking optical fiber connection relationships according to an embodiment of the present application is shown, including a sending end device 1, a first optical fiber distribution box 2, a receiving end device 3 and a second optical fiber distribution box 4.

[0026] The sending end device 1 and the first optical fiber distribution box 2 belong to the equipment of the A substation, and the receiving end device 3 and the first optical fiber distribution box 4 belong to the equipment of the B substation. Specifically, the first optical fiber in the first optical fiber distribution box 2 is connected to the optical fiber interface of the sending end device 1; the second optical fiber in the second optical fiber distribution box 4 is connected to the optical fiber interface of the receiving end device 3.

[0027] It is worth noting that the first optical fiber and the second optical fiber are optical fibers in the same power optical cable, and the number of the first optical fiber and the second optical fiber is multiple. It can also be understood that the first end of the optical fiber in the same optical cable is connected to the optical fiber interface of the sending end device 1, and the second end is connected to the optical fiber interface of the receiving end device 3.

[0028] However, when the operation and maintenance personnel connect the optical fiber to the receiving end device, they do not know which first optical fiber corresponds to the second optical fiber, so they cannot accurately match the interface serial numbers of the first optical fiber and the second optical fiber, which will cause the optical fibers to be out of order or disordered. Based on this, the embodiment of the present application introduces a laser pulse, and determines the correspondence between the first optical fiber and the second optical fiber by the pulse width of the laser pulse.

[0029] In some embodiments, the transmitting device 1 sends a first laser pulse to the receiving device 3 through a first optical fiber. The fiber serial number of the first optical fiber is the same as the fiber interface serial number of the transmitting device 1. For example, if a certain optical fiber is connected to the transmitting device through a fiber interface with serial number 1, the fiber serial number of the optical fiber is 1. Furthermore, the fiber serial numbers of the first optical fibers are different, and the pulse widths of the first laser pulses transmitted by the first optical fibers are different. For example, the serial numbers of the first optical fibers are 1-5, the pulse width of the first laser pulse transmitted by the first optical fiber with serial number 1 is 1*t, the pulse width of the first laser pulse transmitted by the first optical fiber with serial number 2 is 2*t, the pulse width of the first laser pulse transmitted by the first optical fiber with serial number 3 is 3*t, the pulse width of the first laser pulse transmitted by the first optical fiber with serial number 4 is 4*t, and the pulse width of the first laser pulse transmitted by the first optical fiber with serial number 5 is 5*t.

[0030] The receiving end device 3 receives the first laser pulse sent by the transmitting end device 1 through the second optical fiber. Similarly, the optical fiber serial number of the second optical fiber is the same as the optical fiber interface serial number of the receiving end device 3. For example, if an optical fiber is connected to the transmitting end device through an optical fiber interface with serial number 3, the optical fiber serial number of the optical fiber is 3. Furthermore, the optical fiber serial number of the second optical fiber is different, and the pulse width of the first laser pulse transmitted in the second optical fiber is different. For example, the serial number of the second optical fiber is ae, the pulse width of the first laser pulse transmitted in the second optical fiber with serial number a is 2*t, the pulse width of the first laser pulse transmitted in the second optical fiber with serial number b is 3*t, the pulse width of the first laser pulse transmitted in the second optical fiber with serial number c is 4*t, the pulse width of the first laser pulse transmitted in the second optical fiber with serial number d is 1*t, and the pulse width of the first laser pulse transmitted in the second optical fiber with serial number e is 5*t.

[0031] Further, the receiving end device 3 can determine the corresponding relationship between the second optical fiber serial number and the optical fiber serial number of the first optical fiber through the pulse width of the first laser pulse transmitted by the second optical fiber and the pulse width of the first laser pulse transmitted by the first optical fiber. For example, the pulse width of the first laser pulse transmitted by the first optical fiber with serial number 1 is 1*t, the pulse width of the first laser pulse transmitted by the first optical fiber with serial number 2 is 2*t, the pulse width of the first laser pulse transmitted by the first optical fiber with serial number 3 is 3*t, the pulse width of the first laser pulse transmitted by the first optical fiber with serial number 4 is 4*t, and the pulse width of the first laser pulse transmitted by the first optical fiber with serial number 5 is 5*t; the pulse width of the first laser pulse transmitted by the second optical fiber with serial number a is 2*t, the pulse width of the first laser pulse transmitted by the second optical fiber with serial number b is 3*t, the pulse width of the first laser pulse transmitted by the second optical fiber with serial number c is 4*t, the pulse width of the first laser pulse transmitted by the second optical fiber with serial number d is 1*t, and the pulse width of the first laser pulse transmitted by the second optical fiber with serial number e is 5*t. It can be determined that the second optical fiber with sequence number a corresponds to the first optical fiber with sequence number 2, the second optical fiber with sequence number b corresponds to the first optical fiber with sequence number 3, the second optical fiber with sequence number c corresponds to the first optical fiber with sequence number 4, the second optical fiber with sequence number d corresponds to the first optical fiber with sequence number 1, and the second optical fiber with sequence number e corresponds to the first optical fiber with sequence number 5.

[0032] In the embodiment of the present application, the correspondence between the first optical fiber and the second optical fiber is determined by different pulse widths, so that it is possible to determine whether the optical fibers in the same optical cable are out of order or disordered, thereby solving the problem that the operation and maintenance personnel cannot check the order of the optical fibers when the optical cable is fused incorrectly, thereby improving the operation and maintenance efficiency and saving troubleshooting time.

[0033] In some embodiments of the present application, the receiving end device 3 is specifically used to obtain a pulse width range pre-set based on the pulse width of the first laser pulse; based on the pulse width range corresponding to the pulse width of the first laser pulse transmitted by the second optical fiber, determine the correspondence between the optical fiber number of the second optical fiber and the optical fiber number of the first optical fiber.

[0034] Exemplarily, the pulse width of the first laser pulse transmitted by the first optical fiber numbered 1 is 1*t, the pulse width of the first laser pulse transmitted by the first optical fiber numbered 2 is 2*t, the pulse width of the first laser pulse transmitted by the first optical fiber numbered 3 is 3*t, the pulse width of the first laser pulse transmitted by the first optical fiber numbered 4 is 4*t, and the pulse width of the first laser pulse transmitted by the first optical fiber numbered 5 is 5*t, and based on this, the pulse width range of the first laser pulse is set to 1*(t-t1, t+t1), 2*(t-t1, t+t1), 3*(t-t1, t+t1), 4*(t-t1, t+t1), and 5*(t-t1, t+t1). At the receiving end device, if the pulse width of the first laser pulse transmitted by the second optical fiber with serial number a is within 2*(t-t1, t+t1), the pulse width of the first laser pulse transmitted by the second optical fiber with serial number b is within 3*(t-t1, t+t1), the pulse width of the first laser pulse transmitted by the second optical fiber with serial number c is within 4*(t-t1, t+t1), the pulse width of the first laser pulse transmitted by the second optical fiber with serial number d is within 1*(t-t1, t+t1), and the pulse width of the first laser pulse transmitted by the second optical fiber with serial number e is within 5*(t-t1, t+t1), then it can be determined that the second optical fiber with serial number a corresponds to the first optical fiber with serial number 2, the second optical fiber with serial number b corresponds to the first optical fiber with serial number 3, the second optical fiber with serial number c corresponds to the first optical fiber with serial number 4, the second optical fiber with serial number d corresponds to the first optical fiber with serial number 1, and the second optical fiber with serial number e corresponds to the first optical fiber with serial number 5.

[0035] In the embodiment of the present application, the receiving end device may have inaccurate recognition when identifying the pulse width of the laser pulse, so the recognition is made more accurate by setting the time range.

[0036] In some embodiments of the present application, Figure 2 As shown, the transmitting end device 1 includes a first single chip microcomputer, a relay, a laser transmitter, and a step-down power supply.

[0037] Among them, the relay can be replaced by a MOS tube.

[0038] Furthermore, the laser transmitter and the relay controller are connected via a relay control line, and the relay and the first single-chip microcomputer are connected via a single-chip microcomputer signal line. Specifically, the first single-chip microcomputer is used to send signals with different pulse widths to the relay; the relay controls the multiple laser transmitters to send the first laser pulses with different pulse widths according to the signals with different pulse widths; and the step-down power supply is used to reduce the input power supply to power the laser transmitter and the relay.

[0039] In some embodiments, the step-down power supply includes a first step-down power supply and a second step-down power supply. The first step-down power supply powers the relay, and the second step-down power supply powers the laser transmitter to prevent large-scale current fluctuations when the laser transmitter is working from impacting the relay and causing relay operation disorder.

[0040] In some embodiments, the transmitting end device 1 controls the start and stop of the laser transmitter through a relay, so that multiple laser transmitters can send first laser pulses with different pulse widths without setting the laser transmitter, thereby facilitating universal replacement of easily damaged laser transmitters.

[0041] In some embodiments of the present application, Figure 3 As shown, the receiving end device 3 includes a second single chip microcomputer, a laser sensor, a third step-down power supply and a digital tube;

[0042] The laser sensor receives laser pulses with different pulse widths through the second optical fiber, converts the laser pulses with different pulse widths into multiple electrical signals, and sends the multiple electrical signals to the second single chip microcomputer;

[0043] The second single chip computer compares the pulse widths in the plurality of electrical signals with the pulse width of the first laser pulse to determine the corresponding relationship between the fiber serial number of the second optical fiber and the fiber serial number of the first optical fiber;

[0044] The third step-down power supply is used to reduce the input voltage to supply power to the receiving end device;

[0045] The digital tube is used to display the optical fiber serial numbers of the second optical fibers corresponding to the optical fiber serial numbers of the first optical fibers.

[0046] In the embodiment of the present application, the operation and maintenance personnel can directly obtain the fiber sequence number of the first optical fiber corresponding to the second optical fiber through the digital tube, so as to determine whether the optical fibers in the same optical cable are out of order or disordered, thereby solving the problem that the operation and maintenance personnel cannot check the optical fiber sequence when the optical cable is fused incorrectly, thereby improving the operation and maintenance efficiency and saving troubleshooting time.

[0047] In some embodiments, if the fiber number of the first optical fiber corresponding to the fiber number of at least one second optical fiber displayed in the digital tube is 0, it means that the receiving end device has not detected the first laser pulse on at least one second optical fiber or detected that the pulse width corresponding to the first laser pulse does not belong to the pulse width range of the first laser pulse.

[0048] In some embodiments, if the optical fiber number of the first optical fiber corresponding to the second optical fiber displayed in the digital tube is 0, although the interrupted optical fiber cannot perform laser communication, the operation and maintenance personnel can infer the optical fiber number of the optical fiber through other displayed optical fiber numbers.

[0049] In some embodiments, the transmitting device and the receiving device are externally connected to a 12V safety voltage to prevent electric shock.

[0050] It should be noted that this application is not limited to Figure 1 The optical fiber connection relationship troubleshooting system shown in the figure can be any system, device or framework that can implement the business logic of the present application. Figure 1 This is for exemplary purposes only.

[0051] Figure 4 A schematic diagram of a process of checking a fiber connection relationship according to an embodiment of the present application is shown. Figure 4 It can be seen that the method may include steps S101 to S103:

[0052] Step S101: Determine the pulse width of a first laser pulse sent by a transmitting end device through a first optical fiber.

[0053] There are multiple first optical fibers, the optical fiber numbers of the first optical fibers are different, and the pulse widths of the first laser pulses transmitted by the first optical fibers are different.

[0054] Step S102: Determine the pulse width of the first laser pulse received by the receiving end device based on the second optical fiber.

[0055] There are multiple second optical fibers, the optical fiber numbers of the second optical fibers are different, and the pulse widths of the first laser pulses transmitted by the second optical fibers are different.

[0056] Step S103: determining a correspondence between the fiber number of the second optical fiber and the fiber number of the first optical fiber based on the pulse width of the first laser pulse transmitted by the second optical fiber and the pulse width of the first laser pulse transmitted by the first optical fiber.

[0057] In an embodiment of the present application, by determining the pulse width of the first laser pulse sent by the transmitting device through the first optical fiber, and the pulse width of the first laser pulse received by the receiving device based on the second optical fiber, since the pulse width of the first laser pulse transmitted in the same optical fiber is the same, by comparing the pulse widths of the laser pulses transmitted by each optical fiber at the receiving device and the transmitting device, it can be determined that the optical fiber with the same pulse width transmitting the first laser pulse in the first optical fiber and the second optical fiber is the same optical fiber, thereby being able to determine whether the optical fibers in the same optical cable are out of order or disordered, thereby solving the problem that the operation and maintenance personnel cannot check the order of the optical fibers when the optical cable is fused incorrectly, thereby improving the operation and maintenance efficiency and saving the troubleshooting time.

[0058] In some embodiments of the present application, in the above method, step S103 can be specifically implemented as follows: obtaining a pulse width range pre-set based on the pulse width of the first laser pulse, and determining the correspondence between the fiber number of the second optical fiber and the fiber number of the first optical fiber based on the pulse width range corresponding to the pulse width of the first laser pulse transmitted by the second optical fiber.

[0059] In some embodiments of the present application, the optical fiber serial numbers of the second optical fibers and the optical fiber serial numbers of the first optical fibers corresponding to them are displayed on a digital tube of the receiving end device.

[0060] In some embodiments of the present application, if the receiving end device does not detect the first laser pulse on at least one second optical fiber or detects that the pulse width corresponding to the first laser pulse does not fall within the pulse width range of the first laser pulse, it is determined that at least one second optical fiber is interrupted, and the optical fiber number of the first optical fiber corresponding to the optical fiber number of at least one second optical fiber in the digital tube is 0.

[0061] Figure 5 A comparative schematic diagram of an optical fiber connection relationship provided in an embodiment of the present application is shown below. Figure 1-Figure 5 , a method for checking the optical fiber connection relationship provided in an embodiment of the present application is described:

[0062] The optical fiber to be checked (i.e., the first optical fiber) at the transmitting end device is numbered: N+1, N+2, N+3, ... N+SUM. The ports of different laser transmitters of the transmitting end device (ports are 1, 2, 3, ... SUM) are connected to the optical fiber distribution box (N+1, N+2, N+3, ... N+SUM) one by one through the optical fiber interface using optical fiber jumpers, and the power is turned on. The single chip microcomputer divides the signals of different pulse widths (1*t, 2*t, 3*t, ... SUM*t) into multiple channels and sends them to the relay. The relay controls the multiple laser transmitters according to the signals to send laser pulses in a manner of opening and closing with different pulse widths (1*t, 2*t, 3*t, ... SUM*t).

[0063] The corresponding relationship between the optical fiber sequence number and the pulse width at the transmitting end device is shown in Table 1:

[0064] Table 1

[0065] Fiber number of the first optical fiber of the sending device N+1 N+2 N+3 ... N+SUM The optical fiber interface serial number of the optical fiber distribution box corresponding to the first optical fiber 1 2 3 ... SUM Pulse width of laser pulse (port * reference time t) 1*t 2*t 3*t ... SUM*t The channel port number for sending laser pulses 1 2 3 ... SUM

[0066] Laser pulses with different pulse widths (1*t, 2*t, 3*t, ... SUM*t) sent by multiple laser transmitters are transmitted to the receiving end device through different optical fibers (N+1, N+2, N+3, ... N+SUM) in the optical cable.

[0067] The optical fiber to be checked (i.e., the second optical fiber) at the receiving end device is numbered: M+1, M+2, M+3, ...M+SUM. The laser sensor port of the receiving end device (ports 1, 2, 3, ...SUM) is arbitrarily connected to the optical fiber to be checked (M+1, M+2, M+3, ...M+SUM) by means of an optical fiber jumper, and multiple laser sensors receive laser pulse signals of different pulse widths (1*t, 2*t, 3*t, ...SUM*t) respectively and convert them into electrical signals. The laser sensor sends the electrical signal to the single-chip microcomputer, which identifies the pulse width (1*t, 2*t, 3*t, ... SUM*t) in the electrical signal and compares it with the preset pulse width range [1*(t-t1, t+t1), 2*(t-t1, t+t1), 3*(t-t1, t+t1), ... SUM*(t-t1, t+t1)]. If the comparison is consistent, the optical fiber correspondence between the receiving device and the transmitting device is determined, as shown in Table 2. The single-chip microcomputer displays the identified optical fiber correspondence on the digital tube.

[0070] In Table 1 and Table 2, SUM is the number of optical fibers, t is the reference time, t1 is the time range setting parameter, N is the starting number of the optical fiber to be tested at the transmitting end device, and M is the starting number of the optical fiber to be tested at the receiving end device.

[0071] Based on Tables 1 and 2 above, the embodiment of the present application can determine that the optical fiber number of the transmitting end corresponds to the optical fiber number of the receiving end, so that when the optical fiber is broken, the broken optical fiber can be accurately confirmed at the transmitting end and the receiving end, so that repairs can be carried out in time, thereby improving the inspection time and operation and maintenance efficiency.

[0072] In some embodiments of the present application, a device for checking optical fiber connection relationships is provided, and the device for checking optical fiber connection relationships corresponds one-to-one to the method for checking optical fiber connection relationships in the above embodiments. Figure 6As shown, the optical fiber connection relationship checking device includes: a processing module 201. Each functional module is described in detail as follows:

[0073] The processing module 201 is used to determine the pulse width of a first laser pulse sent by a transmitting end device through a first optical fiber, wherein the number of first optical fibers is multiple, the optical fiber numbers of the first optical fibers are different, and the pulse widths of the first laser pulses transmitted by the first optical fibers are different; determine the pulse width of a first laser pulse received by a receiving end device based on a second optical fiber, wherein the number of second optical fibers is multiple, the optical fiber numbers of the second optical fibers are different, and the pulse widths of the first laser pulses transmitted by the second optical fibers are different; and determine the correspondence between the optical fiber number of the second optical fiber and the optical fiber number of the first optical fiber based on the pulse width of the first laser pulse transmitted by the second optical fiber and the pulse width of the first laser pulse transmitted by the first optical fiber.
