[0019] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in connection with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

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

[0021] As described in the background, in the repair and splicing of optical cables, due to line construction connection errors, machine room terminal label errors, connection errors in line splicing and repair, etc., the fiber sequence and tube sequence will be dislocated, crossed and other problems, which will affect the opening of the optical path.

[0022] Currently, the operation and inspection personnel can only rely on the optical time domain reflectometer (OTDR) or optical power meter to detect each fiber in a large number of optical fibers to check the broken optical fibers, which seriously affects the opening of the optical path and the time efficiency of business operation.

[0023] Based on this, the present application provides a method for checking broken optical fibers of a power optical cable. The sending end device sends laser with different pulse widths according to the optical fiber number at the sending end device. The receiving end device receives laser with different pulse widths according to the optical fiber number at the receiving end device. The corresponding relationship between the optical fiber number at the sending end and the laser with different pulse widths is compared, the optical fiber number at the sending end corresponding to the optical fiber number at the receiving end is determined, so that when the optical fiber is broken, the broken optical fiber can be accurately confirmed at the sending end and the receiving end, so that timely maintenance can be performed, and the maintenance time and operation and maintenance efficiency are improved.

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

[0025] Figure 1 A checking system for optical fiber connection relationship according to an embodiment provided by the present application is shown, which includes 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 second 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 with the optical fiber interface of the sending end device 1, and the second optical fiber in the second optical fiber distribution box 4 is connected with the optical fiber interface of the receiving end device 3.

[0027] It should be noted 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 with the optical fiber interface of the sending end device 1, and the second end is connected with the optical fiber interface of the receiving end device 3.

[0028] However, when the operation and maintenance personnel connects the optical fiber with the receiving end device, the operation and maintenance personnel does not know which first optical fiber the second optical fiber corresponds to, so the operation and maintenance personnel cannot accurately correspond the interface serial numbers of the first optical fiber and the second optical fiber, which may cause the problem of disordered optical fiber. Based on this, the embodiment of the present application introduces a laser pulse, and the correspondence between the first optical fiber and the second optical fiber is determined by the pulse width of the laser pulse.

[0029] In some embodiments, the sending end device 1 sends a first laser pulse to the receiving end device 3 through the first optical fiber. The optical fiber serial number of the first optical fiber is the same as the optical fiber interface serial number of the sending end device 1. For example, a certain optical fiber is connected with the sending end device through the optical fiber interface with serial number 1, and the optical fiber serial number of the optical fiber is 1. Further, the optical 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 transmitted by the sending end device 1 through the second optical fiber. Similarly, the fiber serial number of the second optical fiber is the same as the fiber interface serial number of the receiving end device 3. For example, a certain optical fiber is connected with the sending end device through the fiber interface with serial number 3, and the fiber serial number of the optical fiber is 3. Further, the fiber serial numbers of the second optical fibers are different, and the pulse widths of the first laser pulses transmitted in the second optical fibers are different. For example, the serial numbers of the second optical fibers are a-e, 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 correspondence between the serial numbers of the second optical fibers and the serial numbers of the first optical fibers according to the pulse widths of the first laser pulses transmitted by the second optical fibers and the pulse widths of the first laser pulses transmitted by the first optical fibers. 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 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.

[0032] In the embodiments of the present application, the correspondence between the first optical fiber and the second optical fiber is determined by different pulse widths, so that whether the optical fibers in the same optical cable are in the wrong order or in the disorder can be determined, and the problem that the maintenance personnel cannot troubleshoot the order of the optical fibers when the optical cable is fused incorrectly is solved, the operation and maintenance efficiency is improved, and the troubleshooting time is saved.

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

[0034] 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, and based on this, the pulse width range of the first laser pulse is set as 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 belongs to 2*(t-t1, t+t1), the pulse width of the first laser pulse transmitted by the second optical fiber with serial number b belongs to 3*(t-t1, t+t1), the pulse width of the first laser pulse transmitted by the second optical fiber with serial number c belongs to 4*(t-t1, t+t1), the pulse width of the first laser pulse transmitted by the second optical fiber with serial number d belongs to 1*(t-t1, t+t1), and the pulse width of the first laser pulse transmitted by the second optical fiber with serial number e belongs to 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 embodiments of the present application, when the receiving end device identifies the pulse width of the laser pulse, there may be a problem of inaccurate identification, so the time range is set to make the identification more accurate.

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

[0037] The relay can be replaced by a MOS tube.

[0038] Further, the laser transmitter and the relay controller are connected through a relay control line, and the relay and the first single-chip microcomputer are connected through a single-chip microcomputer signal line. Specifically, the first single-chip microcomputer is configured to send signals with different pulse widths to the relay; the relay controls the plurality of laser transmitters to send first laser pulses with different pulse widths according to the signals with different pulse widths; and the step-down power supply is configured to reduce an input power supply to supply power to the laser transmitters 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 supplies power to the relay, and the second step-down power supply supplies power to the laser transmitters, thereby avoiding the impact of large-scale current fluctuations of the laser transmitters on the relay when the laser transmitters are working, and preventing the relay from working disorderly.

[0040] In some embodiments, the sending end device 1 controls the laser transmitters to start and stop through the relay, so that the plurality of laser transmitters can send first laser pulses with different pulse widths without the need to set the laser transmitters, and the laser transmitters which are prone to damage can be easily replaced.

[0041] In some embodiments of the present application, as shown in Figure 3 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 a plurality of electrical signals, and sends the plurality of electrical signals to the second single-chip microcomputer.

[0043] The second single-chip microcomputer compares the pulse widths of the plurality of electrical signals with the pulse width of the first laser pulse, and determines the correspondence between the optical fiber serial numbers of the second optical fiber and the optical fiber serial numbers of the first optical fiber.

[0044] The third step-down power supply is configured to reduce an input voltage to supply power to the receiving end device.

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

[0046] In the embodiments of the present application, the operation and maintenance personnel can directly know the optical fiber serial numbers 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 in disorder, and thus solve the problem that the operation and maintenance personnel cannot troubleshoot the order of the optical fibers when the optical cable is incorrectly fused, improve the operation and maintenance efficiency, and save troubleshooting time.

[0047] In some embodiments, if the fiber serial number of the first fiber corresponding to the second fiber displayed in the nixie tube is 0, it indicates that the receiving end device does not detect the first laser pulse on the at least one second fiber or detects the pulse width corresponding to the first laser pulse, which does not belong to the pulse width range of the first laser pulse.

[0048] In some embodiments, if the fiber serial number of the first fiber corresponding to the second fiber displayed in the nixie tube is 0, although the interrupted fiber cannot perform laser communication, the operator can infer the fiber serial number of the fiber through other displayed fiber serial numbers.

[0049] In some embodiments, the sending end device and the receiving end device are externally connected to a safety voltage of 12V to avoid personal electric shock.

[0050] It should be noted that the present application is not limited to Figure 1 The fiber connection relationship checking system shown, any system or device or framework that can realize the business logic of the present application, Figure 1 is only an example for illustrative purposes.

[0051] Figure 4 The flowchart of a fiber connection relationship checking method according to an embodiment of the present application is shown, from Figure 4 It can be seen that the method can include steps S101-S103:

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

[0053] Wherein, the number of first fibers is multiple, the fiber serial numbers of first fibers are different, and the pulse widths of first laser pulses transmitted by first 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 fiber.

[0055] Wherein, the number of second fibers is multiple, the fiber serial numbers of second fibers are different, and the pulse widths of first laser pulses transmitted by second fibers are different.

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

[0057] In the embodiment of the present application, by determining the pulse width of the first laser pulse transmitted by the sending end device through the first optical fiber and the pulse width of the first laser pulse received by the receiving end 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 end device and the sending end device, the optical fiber in which the pulse width of the first laser pulse transmitted in the first optical fiber and the second optical fiber is the same can be determined as the same optical fiber, so that whether the optical fibers in the same optical cable are out of order or out of sequence can be determined, and the problem that the operation and maintenance personnel cannot troubleshoot the order of the optical fibers when the optical cable is incorrectly fused is solved, the operation and maintenance efficiency is improved, and the troubleshooting time is saved.

[0058] In some embodiments of the present application, in the above method, step S103 can be specifically implemented as: obtaining a pulse width range pre-set based on the pulse width of the first laser pulse, determining the correspondence between the fiber serial number of the second optical fiber and the fiber serial 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 fiber serial number of the first optical fiber corresponding to the fiber serial number of the second optical fiber is displayed on the nixie 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 the pulse width corresponding to the first laser pulse not belonging to the pulse width range of the first laser pulse, it is determined that the at least one second optical fiber is interrupted, and the fiber serial number of the first optical fiber corresponding to the fiber serial number of the at least one second optical fiber in the nixie tube is 0.

[0061] Figure 5 A comparison diagram of the optical fiber connection relationship provided by the embodiment of the present application is shown, and the troubleshooting method of the optical fiber connection relationship provided by the embodiment of the present application will be described below: Figures 1-5

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

[0063] The correspondence between the fiber serial number and the pulse width at the sending end device is shown in Table 1, for example:

[0064] Table 1

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

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

[0067] The to-be-checked optical fibers (i.e., the second optical fibers) at the receiving end device are numbered: M+1, M+2, M+3,...M+SUM. The laser sensor ports (ports 1, 2, 3,...SUM) of the receiving end device are connected to the to-be-checked optical fibers (M+1, M+2, M+3,...M+SUM) by means of fiber jumpers, and the plurality of laser sensors respectively receive laser pulse signals of different pulse widths (1*t, 2*t, 3*t,...SUM*t) and convert them into electrical signals. The laser sensors send the electrical signals to the single-chip microcomputer, which compares the pulse widths (1*t, 2*t, 3*t,...SUM*t) in the electrical signals with the preset pulse width ranges [1*(t-t1, t+t1), 2*(t-t1, t+t1), 3*(t-t1, t+t1),...SUM*(t-t1, t+t1)] and determines the fiber correspondence relationship between the receiving end device and the sending end device when the comparison is consistent, as shown in Table 2. The single-chip microcomputer displays the identified fiber correspondence relationship to the nixie tube.
