Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0023] Example 1

[0024] According to an embodiment of the present invention, an embodiment of a fault location method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0025] Figure 1 This is a flowchart of a fault location method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0026] Step S102: Receive fault information and initial latitude and longitude set, wherein the fault information is the information sent by the monitoring equipment after detecting the occurrence of a fault event, and the initial latitude and longitude set is the latitude and longitude information of multiple key location points calculated by the cloud platform;

[0027] Step S104: Based on the above fault information and the above initial latitude and longitude set, perform matching calculation processing to obtain the target latitude and longitude information;

[0028] Step S106: Send the above target latitude and longitude information to the smart device corresponding to the target maintenance personnel.

[0029] In this embodiment of the invention, the execution subject of the fault location method in steps S102 to S108 is a fault location system. The system receives fault information and an initial latitude and longitude set. The fault information is information sent by the monitoring equipment after detecting a fault event. The initial latitude and longitude set is the latitude and longitude information of multiple key location points calculated by the cloud platform. Based on the fault information and the initial latitude and longitude set, a matching calculation is performed to obtain the target latitude and longitude information. The target latitude and longitude information is then sent to the intelligent device corresponding to the target maintenance personnel.

[0030] As an optional embodiment, the above system includes an OTDR (Optical Time Domain Reflectometer), a sensing information conveyor belt, numbered magnetic field sensing points, a cloud information platform, a GIS map, and utilizes data from an optical cable detector. Based on the magnetic field information detected by the sensing information conveyor belt attached to the optical cable, the numbered magnetic field sensing points, and the latitude and longitude information fed back by the optical cable detector, the latitude and longitude of each magnetic field sensing point and the optical cable are located, thereby achieving the effect of accurately inferring the location of fault points / points with high optical attenuation.

[0031] It should be noted that OTDR (Optical Time Domain Reflectometer) is connected to each fiber core of the optical cable and used to provide feedback on the distance to the detected fault point. The induction information conveyor belt and numbered magnetic field sensing points are attached to the outside of the optical cable. The induction information conveyor belt transmits information such as the number of each sensing point and the signal strength. The numbered magnetic field sensing points are numbered sequentially from one end of the optical cable to the other. Generally, the distances between each sensing point are equal or form a certain mathematical relationship (such as a linear relationship). These sensing points are used to sense and record the electromagnetic signal strength emitted by the optical cable detector. Magnetic field sensing points can exist in a form that surrounds the location of the optical cable, etc., with the aim of sensing the strongest magnetic field signal. The cloud information platform is mainly used to collect and summarize information collected by each numbered magnetic field sensing point, information such as the location and burial depth detected by the optical cable detector, optical port location information (latitude and longitude), and information on optical cable breakage fault points. GIS Map and Computer / CPU: Based on the location and burial depth information detected and fed back by the optical cable detector and the information collected by the magnetic field induction points, the computer calculates the latitude and longitude information corresponding to each induction point, calculates new fault points, pushes new latitude and longitude based on regional differences, and corrects the fault location point data information.

[0032] In an optional embodiment, receiving fault information includes: setting an optical time domain reflectometer on the fiber core of the target optical cable, wherein the optical time domain reflectometer is used to monitor whether the fault event has occurred; when the fault event occurs, the optical time domain reflectometer generates fault distance information; receiving the fault distance information, and determining the fault information based on the fault distance information.

[0033] As an optional embodiment, such as Figure 2 The diagram illustrates the fault location point push process. When an OTDR detects a noticeable step at a specific location, it provides distance information. The computer matches this information with the modeled fiber optic cable's latitude and longitude to calculate the location's coordinates. Based on the OTDR's distance information and the modeled data, the cloud platform and GIS perform calculations. When the distance to the fault point or point of high optical attenuation lies between two magnetic field sensing points, the latitude and longitude are calculated in a straight line and according to a specific scale. Finally, the location point is pushed to maintenance personnel via a GIS map.

[0034] In an optional embodiment, receiving the initial latitude and longitude set includes: using an optical fiber detector to perform motion detection processing on the target area to determine the detection information of the target area, wherein the target area includes the multiple key location points, and the detection information includes: the initial latitude and longitude information, depth information, and detection time information of the multiple key location points; using a magnetic field sensing device to perform detection processing to obtain magnetic field strength information, wherein the magnetic field sensing device is set at a preset distance according to the device number, and the magnetic field strength information includes: magnetic field strength and the device number; feeding back the detection information and the magnetic field strength information to a cloud platform, wherein the cloud platform is used to perform calculation processing on the detection information and the magnetic field strength information to obtain calculation results; receiving the calculation results, and determining the initial latitude and longitude set based on the calculation results.

[0035] As an optional embodiment, such as Figure 3 The diagram illustrates the fiber optic cable node latitude and longitude positioning process. The fiber optic cable detector locates the cable position, repeatedly moving and probing key areas. The detector feeds back the detected latitude and longitude, burial depth, and detection time to the cloud platform. Numbered magnetic field induction points report the detected magnetic field strength and their numbers to the cloud platform. The cloud platform matches the time when each numbered magnetic field induction point receives the strongest field strength with the latitude and longitude information from the fiber optic cable detector to determine the latitude and longitude of the monitoring points in the detection area. Based on the numbers and distances of other detection points and the latitude and longitude of already detected induction points, the platform simulates the latitude and longitude of various key locations along the underground fiber optic cable.

[0036] It should be noted that because the distance to each magnetic field sensing point is a constant, the latitude and longitude of other sensing points can be inferred from their distances to the already detected points and the information from the already detected points. This allows for the calculation of the distance between each sensing point and the two ends of the optical cable, which is also the distance measured by the accurately calibrated OTDR. The computer can then model the latitude and longitude information of the underground optical cable based on the detection point data.

[0037] In an optional embodiment, the above-mentioned matching calculation process based on the fault information and the initial latitude and longitude set to obtain the target latitude and longitude information includes: performing matching processing on the fault information based on the initial latitude and longitude set to determine whether there is initial latitude and longitude information corresponding to the fault information; if there is initial latitude and longitude information corresponding to the fault information, then determining the detection information corresponding to the initial latitude and longitude information as the target latitude and longitude information; if there is no initial latitude and longitude information corresponding to the fault information, then calculating the target latitude and longitude information based on the detection information adjacent to the fault information.

[0038] As an optional embodiment, based on the sensing information conveyor belt attached to the optical cable and numbered magnetic field sensing points, the distances to various locations on the optical cable are determined, and the magnetic field strength information of the optical cable detector is sensed. The time points when the numbered magnetic field sensing points receive the strongest field strength are matched one-to-one with the latitude and longitude information of the optical cable detector to determine the latitude and longitude information of each magnetic field sensing point, thereby enabling the calculation of the latitude and longitude information of the fault point / location of the point with the greatest optical attenuation. Finally, the distance and actual latitude and longitude of the new fault point step are measured using an OTDR, and compared with the inferred results. Continuous adjustments are made, and a large data comparison database is established, thereby achieving the effect of accurately inferring the location of the fault point / location of the point with the greatest optical attenuation.
