Description

Technical Field

[0001] This invention belongs to the field of hollow optical cable fault detection technology, specifically relating to an auxiliary detection system and method for locating faults in hollow optical cables. Background Technology

[0002] Hollow-core optical cable is a new type of optical communication technology. Since 2025, it has gradually moved from the laboratory to commercial engineering. Compared with traditional solid-core optical cable, hollow-core optical cable has the following characteristics: (1) Different transmission media. For hollow-core optical cable, light propagates in the central air (or vacuum) hole and is guided by the photon bandgap effect or anti-resonance reflection, avoiding direct interaction with glass materials. For traditional solid-core optical cable, light is transmitted in the solid glass fiber core (usually silicon dioxide) by total internal reflection, which will directly interact with glass materials; (2) Better transmission speed. The speed of light in air is about 30% faster than in glass (air refraction). (3) Lower nonlinear effects and dispersion. The interaction between light and glass is minimal, which can significantly reduce nonlinear distortion and dispersion, making it suitable for high-power transmission and large-capacity communication; (4) Lower optical loss. Currently, domestic research teams have achieved an ultra-low loss of 0.052dB / km, which is far lower than that of traditional optical cables. Therefore, hollow optical cables have significant advantages in the fields of low latency, high bandwidth, low loss, and long-distance transmission, thanks to the above-mentioned excellent transmission performance. For example, they are of great significance in scenarios such as data center interconnection, high-frequency trading (securities), long-distance trunk communication, and supercomputing.

[0003] Unlike solid optical cables where contaminants adhere to the surface, hollow optical cables, being hollow in the middle, allow moisture or dust to directly enter the light-guiding area, altering optical properties or blocking the light path. In severe cases, this can directly cause signal interruption. Therefore, hollow optical cables are more sensitive to the environment. Furthermore, due to different reflection characteristics, traditional OTDRs (Optical Time Domain Reflectometers) rely on the reflection characteristics of glass for fault detection. However, the reflection signal of hollow optical fibers may be abnormal, leading to inaccurate fault location. Additionally, the lack of dedicated testing tools (most commercially available testing equipment is only optimized for traditional optical cables, requiring customized tools or parameter adjustments) further complicates fault diagnosis and location in hollow optical cables.

[0004] Currently, since hollow-core optical cables have only recently been commercially deployed in engineering projects, traditional testing equipment is based on traditional solid-core optical cables and cannot be applied to hollow-core optical cables. It is also impossible to distinguish the location and cause of signal attenuation. Therefore, in actual use, in order to reduce optical cable failures, strict end-face cleaning and junction box sealing must be carried out during the engineering construction process, thereby preventing failures in advance based on preventive measures.

[0005] Therefore, given the aforementioned shortcomings, how to provide an auxiliary detection system applicable to fault location in hollow optical cables, so as to realize fault detection and prevention in hollow optical cables, has become an urgent problem to be solved. Summary of the Invention

[0006] The purpose of this invention is to provide an auxiliary detection system and method for locating faults in hollow optical cables, in order to solve the problem that existing fault detection equipment is designed for traditional solid optical cables and cannot be applied to hollow optical cables, thus making it impossible to detect faults in hollow optical cables.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: Firstly, an auxiliary detection system for locating faults in hollow optical cables is provided, comprising: Several water vapor and dust detection devices are provided, wherein each splice box of the hollow optical cable is equipped with one of the aforementioned water vapor and dust detection devices, and each water vapor and dust detection device is used to detect the water vapor data and dust data in its corresponding splice box, and upload the water vapor data and dust data in each splice box to the hollow optical cable splice box detection management platform. The hollow optical cable splice box testing and management platform is used to receive water vapor and dust data uploaded by various water vapor and dust detection devices, as well as to obtain the signal receiving power of the hollow optical cable and the historical test data corresponding to each water vapor and dust detection device. The hollow optical cable junction box detection and management platform is also used to determine the faulty junction box on the hollow optical cable based on the signal receiving power, the historical detection data corresponding to each water vapor and dust detection device, and the water vapor and dust data uploaded by each water vapor and dust detection device.

[0008] Based on the above disclosure, this invention achieves proactive monitoring and precise fault diagnosis of environmentally sensitive factors in hollow optical cables by deploying moisture and dust detection devices in each splice box of the hollow optical cable and combining them with a hollow optical cable splice box detection management platform. Specifically, addressing the pain point of hollow optical cables being highly sensitive to moisture and dust, and the difficulty of accurate location by traditional OTDRs, this invention utilizes real-time collected moisture and dust data, combined with signal reception power and historical detection data for comprehensive analysis. This effectively distinguishes abnormal environmental conditions within different splice boxes, thereby accurately identifying the specific location of the fault and solving the problem of traditional detection methods failing. Therefore, this invention provides an auxiliary judgment and location technology for faults in hollow optical cables caused by moisture and dust, improving maintenance efficiency and reducing hollow optical cable faults.

The analysis module is also used to determine whether the signal receiving power meets the preset conditions, and when it is determined that the signal receiving power does not meet the preset conditions, it determines that the abnormal junction box is a faulty junction box. An alarm module, electrically connected to the analysis module, is used to issue an alarm notification after the analysis module identifies a faulty junction box on the hollow optical cable.

[0010] In one possible design, the analysis module is used to generate a water vapor curve based on the water vapor data uploaded by each water vapor and dust detection device within the same acquisition period, and to generate a dust curve based on the dust data uploaded by each water vapor and dust detection device within the same acquisition period.

[0011] In one possible design, the analysis module is used to determine, based on the water vapor curve, whether the data difference between the water vapor data uploaded by any water vapor dust detection device and the mean of the water vapor data uploaded by all other water vapor dust detection devices is greater than a water vapor threshold; and / or Based on the dust curve, if the difference between the dust data uploaded by any of the water vapor dust detection devices and the average dust data uploaded by the other water vapor dust detection devices is greater than the dust threshold, the junction box where that water vapor dust detection device is located is determined to be an abnormal junction box.

[0012] In one possible design, the historical detection data includes historical water vapor data and historical dust data; The analysis module is used to compare the water vapor data uploaded by each water vapor and dust detection device with the historical water vapor data corresponding to each water vapor and dust detection device, and to compare the dust data uploaded by each water vapor and dust detection device with the historical dust data corresponding to each water vapor and dust detection device. When the difference between the average value of the water vapor data of any water vapor and dust detection device and the average value of the corresponding historical water vapor data is greater than the water vapor threshold, and / or the difference between the average value of the dust data of any water vapor and dust detection device and the average value of the corresponding historical dust data is greater than the dust threshold, the junction box where the water vapor and dust detection device is located is determined to be an abnormal junction box.

[0013] In one possible design, the alarm module is also used to obtain the location information of the faulty junction box and generate the alarm prompt based on the location information.

[0014] In one possible design, any water vapor and dust detection device includes: a water vapor detection module, a dust detection module, a power supply module, a control module, and a communication module, wherein the water vapor detection module and the dust detection module are electrically connected to the control module, and the power supply module is electrically connected to the power supply terminals of the water vapor detection module, the dust detection module, the control module, and the communication module. The moisture detection module is used to detect the moisture data in the corresponding junction box and transmit the moisture data to the control module. The dust detection module is used to detect dust data in the corresponding junction box and transmit the dust data to the control module. The control module is connected to the hollow optical cable junction box detection and management platform via the communication module, and is used to upload the received water vapor data and dust data to the hollow optical cable junction box detection and management platform via the communication module.

[0015] In one possible design, the power module is also used to send power to the control module, so that the control module can send the power to the hollow optical cable junction box detection and management platform through the communication module. The hollow optical cable junction box detection and management platform is also used to generate a battery replacement prompt when the power of any water vapor and dust detection device is lower than the power threshold.

[0016] In one possible design, the communication module may employ a 4G communication module, a 5G communication module, and / or a BeiDou communication module.

[0017] Secondly, an auxiliary detection method for fault location of hollow optical cables is provided. This method is implemented based on the auxiliary detection system for fault location of hollow optical cables, designed according to the first aspect or any possible design within the first aspect. The auxiliary detection system includes several water vapor and dust detection devices, and one of these water vapor and dust detection devices is installed in each junction box of the hollow optical cable. The method includes: Each moisture and dust detection device detects the moisture and dust data in its corresponding junction box and uploads the moisture and dust data in each junction box to the hollow optical cable junction box detection management platform; The hollow optical cable splice box testing and management platform receives water vapor and dust data uploaded by various water vapor and dust detection devices, as well as obtains the signal receiving power of the hollow optical cable and the historical testing data corresponding to each water vapor and dust detection device.

[0021] Beneficial effects: (1) This invention deploys a water vapor and dust detection device in each junction box of the hollow optical cable and combines it with a hollow optical cable junction box detection management platform to achieve active monitoring and accurate fault diagnosis of environmentally sensitive factors of the hollow optical cable.

Therefore, this invention provides an auxiliary judgment and location technology for faults caused by water vapor and dust in hollow optical cables, which improves maintenance efficiency and reduces the failure of hollow optical cables. Thus, this solution can provide reliable operation and maintenance guarantee for the engineering application of hollow optical cables in low latency and high bandwidth scenarios, and improve the availability and maintenance efficiency of hollow optical cables.

Detailed Implementation

[0023] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0024] It should be understood that although the terms first, second, etc., may be used herein to describe various units, these units should not be limited by these terms. These terms are only used to distinguish one unit from another. For example, a first unit may be referred to as a second unit, and similarly, a second unit may be referred to as a first unit, without departing from the scope of the exemplary embodiments of the invention.

[0025] It should be understood that the term "and / or" that may appear in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously. The term " / and" that may appear in this document describes another relationship between related objects, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " that may appear in this document generally indicates that the related objects before and after it are in an "or" relationship.

[0026] Example: See Figures 1-3 As shown, the auxiliary detection system for hollow optical cable fault location provided in this embodiment detects and collects data on moisture and dust inside the hollow optical cable splice box, performs comparative analysis, and then combines this data with the received optical power signal value to achieve fault location and prevention in the hollow optical cable. The reason for focusing fault detection on the splice box in this embodiment is as follows: Optical cable splice boxes are the weakest link in optical cable lines, most susceptible to water and dust ingress. This is because they are assembled on-site, requiring opening, fiber splicing, fiber coiling, and resealing, unlike the fully sealed structure of the optical cable itself, which is manufactured in a factory. Furthermore, the sealing and waterproofing of splice boxes rely on manual labor and materials. If they are not properly cleaned, not tightly pressed, or the adhesive is not fully dissolved during installation, moisture, humidity, and dust will slowly seep in. Since splice boxes are typically installed outdoors or in the field, temperature changes, rain, and soil pressure can all cause the seal to gradually fail. Hollow-core optical cables are highly sensitive to moisture and dust. Once moisture and dust enter the air pores, they directly scatter and absorb light signals, causing a sudden spike in loss and even link interruption. Thus, moisture and dust ingress into splice boxes is a major cause of hollow-core optical cable failures. Based on these characteristics, this embodiment proposes a technical solution for detecting hollow-core optical cable faults by collecting and analyzing data on moisture and dust levels inside the splice boxes, and then combining this data with the received optical power signal values.

[0027] Among them, see Figure 1 As shown, the auxiliary detection system for fault location of hollow optical cables may include, but is not limited to, a hollow optical cable junction box detection and management platform and several water vapor and dust detection devices.

[0028] In specific implementation, for example, each splice box of the hollow optical cable is equipped with a water vapor and dust detection device. Each water vapor and dust detection device is used to detect the water vapor and dust data in its corresponding splice box and upload the water vapor and dust data in each splice box to the hollow optical cable splice box detection management platform, thereby realizing real-time uploading of detection data. Optionally, for example, each water vapor and dust detection device can collect and upload water vapor and dust data according to a preset collection cycle and upload cycle (such as hourly, 4-hour, or daily). Of course, the specific collection cycle and upload cycle can be set according to actual use, and this embodiment is not limited to the above example.

[0029] Furthermore, the detailed composition and structure of the water vapor and dust detection device are disclosed below.

[0030] Optionally, any water vapor and dust detection device may include, but is not limited to, a water vapor detection module, a dust detection module, a power supply module, a control module, and a communication module; wherein, the water vapor detection module and the dust detection module are electrically connected to the control module to upload the collected data; at the same time, the power supply module is electrically connected to the power supply terminals of the water vapor detection module, the dust detection module, the control module, and the communication module, that is, the power supply module supplies power to the aforementioned modules, thereby ensuring the normal operation of any water vapor and dust detection device.

[0031] For specific applications, see Figure 2 As shown, the moisture detection module is used to detect moisture data in the corresponding junction box and transmit the moisture data to the control module; similarly, the dust detection module is used to detect dust data in the corresponding junction box and transmit the dust data to the control module; simultaneously, the control module communicates with the hollow optical cable junction box detection management platform through the communication module, and is used to upload the received moisture and dust data to the hollow optical cable junction box detection management platform through the communication module; thus, each moisture and dust detection device can use its own moisture and dust detection modules to collect moisture and dust data, and then use the communication module to upload the collected moisture and dust data, thereby providing a data foundation for subsequent fault diagnosis.

[0032] It should be noted that the water vapor detection module and dust detection module can be selected according to the actual use, such as choosing a water vapor volume concentration real-time monitoring module based on laser technology, etc. This embodiment does not make specific limitations.

[0033] Optionally, the communication module described in the example may be, but is not limited to, a 4G communication module, a 5G communication module, and / or a BeiDou communication module. In this way, the water vapor and dust detection device can use 4G, 5G, and / or BeiDou communication networks to achieve positioning and data transmission and reception with the management platform. Meanwhile, the power module may be, but is not limited to, a lithium battery.

[0034] After each water vapor and dust detection device uploads its collected water vapor and dust data, the hollow optical cable junction box detection and management platform can then use the uploaded data to perform fault detection and location of the hollow optical cable. The process is as follows: The hollow optical cable splice box detection and management platform is used to receive water vapor and dust data uploaded by various water vapor and dust detection devices, and to obtain the signal receiving power of the hollow optical cable and the historical detection data corresponding to each water vapor and dust detection device (the historical detection data includes historical water vapor data and historical dust data). Then, based on the signal receiving power, the historical detection data corresponding to each water vapor and dust detection device, and the water vapor and dust data uploaded by each water vapor and dust detection device, the platform determines the faulty splice box on the hollow optical cable.

[0035] Optionally, the detailed architecture of the hollow optical fiber splice closure testing and management platform is disclosed below, and based on this, the fault detection process of hollow optical fiber cables is specifically described: In specific implementation, the hollow optical cable splice box detection and management platform described above may include, but is not limited to, a storage module, an analysis module, and an alarm module. The storage module stores water vapor and dust data uploaded by each water vapor and dust detection device. The analysis module is electrically connected to the storage module and is used to perform a horizontal comparison of the water vapor and dust data uploaded by each water vapor and dust detection device within the same acquisition period, according to a comparison method based on the same data type; and / or to perform a vertical comparison of the water vapor and dust data uploaded by each water vapor and dust detection device with their respective historical detection data, thereby identifying abnormal splice boxes on the hollow optical cable after horizontal and / or vertical comparisons.

[0036] It should be noted that this implementation uses horizontal comparison and / or vertical comparison to determine anomalies in the junction box; the horizontal comparison method is as follows: The analysis module is used to generate a water vapor curve based on the water vapor data uploaded by various water vapor and dust detection devices within the same acquisition period (see [link]). Figure 3 As shown in the figure, a dust curve is generated based on the dust data uploaded by each water vapor and dust detection device within the same collection period; then, based on the water vapor curve and the dust curve, the water vapor data and dust data uploaded by each water vapor and dust detection device within the same collection period are compared horizontally to determine the abnormal junction box.

[0037] Specifically, when making a horizontal comparison based on the water vapor curve and the dust curve, the analysis module is used to determine, based on the water vapor curve, that the data difference between the water vapor data uploaded by any water vapor and dust detection device and the average value of the water vapor data uploaded by all other water vapor and dust detection devices is greater than the water vapor threshold, and / or based on the dust curve, determine that the junction box where any water vapor and dust detection device is located is an abnormal junction box.

[0038] See Figure 3 As shown, Figure 3 This represents the moisture curve of a junction box within a certain section of a hollow optical cable. If the moisture data of a certain junction box is greater than that of other junction boxes, the moisture content of that junction box is determined to be abnormal, i.e., the moisture content is too high. Furthermore, to ensure the accuracy of the detection, an average value method can be used for anomaly judgment. That is, when comparing any moisture and dust detection device, the average value of the moisture data of the remaining moisture and dust detection devices is calculated. Then, the moisture data of any moisture and dust detection device is compared with the average value. If the absolute value of the difference is greater than the moisture threshold, the junction box where any moisture and dust detection device is located is determined to be an abnormal junction box. In this embodiment, the second method is preferred for anomaly judgment.

[0039] Similarly, the principle of dust anomaly detection is the same as that of water vapor anomaly detection, and will not be elaborated here.

[0040] Based on this, by making a horizontal comparison, if the difference between the water vapor data and / or dust data of any water vapor and dust detection device and their respective mean values ​​is greater than the corresponding threshold value, it can be determined that there is an abnormality in water vapor and / or dust in the junction box where the water vapor and dust detection device is located.

[0041] Meanwhile, the longitudinal comparison of a single junction box involves comparing the data detected by a particular junction box with its historical detection data. Specifically, the analysis module compares the water vapor data uploaded by each water vapor and dust detection device with the corresponding historical water vapor data for each device, and compares the dust data uploaded by each device with the corresponding historical dust data. If the difference between the average water vapor data of any water vapor and dust detection device and the average historical water vapor data is greater than a water vapor threshold, and / or the difference between the average dust data of any water vapor and dust detection device and the average historical dust data is greater than a dust threshold, the junction box containing that water vapor and dust detection device is determined to be an abnormal junction box.

[0042] In this embodiment, when performing longitudinal comparison, data within the same collection period is also used. For example, if the current water vapor data is the data of junction box 3 from 2:00 to 6:00 on December 21, 2025, then the historical water vapor data can be the data of junction box 3 from 2:00 to 6:00 on December 18-20, 2025.

[0043] Thus, through the aforementioned horizontal and / or vertical comparisons, abnormal junction boxes can be identified. However, detecting moisture or dust entering the junction box only indicates a high probability of a fault in the hollow optical cable, not necessarily that moisture or dust has entered the cable itself. Therefore, further fault diagnosis is needed, combining this data with the collected received power of the hollow optical cable. The process is as follows: The analysis module is also used to determine whether the signal received power meets a preset condition, and when it is determined that the signal received power does not meet the preset condition, it determines that the abnormal junction box is a faulty junction box; in specific implementation, for example, the aforementioned preset condition is that the signal received power is greater than or equal to a power threshold, that is, if Figure 1 If the received signal power of the local B receiver is less than the power threshold, it indicates that the hollow optical cable has experienced signal fragmentation or interruption. In this case, the abnormal junction box is determined to be a faulty junction box, and an alarm should be issued. That is, the alarm module is electrically connected to the analysis module and is used to issue an alarm after the analysis module determines that the faulty junction box on the hollow optical cable, so as to realize timely maintenance or replacement of the faulty junction box, thereby ensuring the stable communication of the hollow optical cable.

[0044] In this embodiment, the alarm module is also used to obtain the location information of the faulty junction box (using Beidou positioning or GPS positioning); thus, the alarm prompt can be generated based on the location information, which facilitates maintenance personnel to locate the faulty junction box in a timely manner, thereby quickly reaching the fault point for fault handling and improving maintenance efficiency; of course, the alarm prompt can also be set with the corresponding fault cause, such as abnormal water vapor and / or abnormal dust, so that maintenance personnel can understand the cause of the fault and then handle the corresponding fault.

[0045] Furthermore, if the strength of the received signal from the hollow optical cable is greater than or equal to the power threshold, but an abnormality of moisture and / or dust is detected in the junction box during the first step of detection, maintenance prompts can also be output to allow for resealing or replacement of the abnormal junction box, thus achieving preventative measures.

[0046] Furthermore, the aforementioned moisture and dust thresholds can be specifically set according to actual use. Setting the thresholds too low will increase maintenance workload and costs. Moreover, the probability of moisture intrusion varies in different construction environments and regions. Therefore, the thresholds can be adjusted by comparing the received optical cable signal power and the collected data at the receiving end. At the same time, if there is no significant attenuation of the optical fiber received signal after a period of time (such as 10 days, 1 month, or half a year) of abnormal data collection, data comparison can continue, and the alarm threshold can be gradually increased until the critical point (when the signal power is less than the power threshold) is reached. Of course, the thresholds are predetermined and are not considered as specific fault detection processing steps provided in this implementation.

[0047] In addition, the power modules of each water vapor and dust detection device can automatically detect power usage and upload the power level to the system platform in real time, thereby realizing power level warning. That is, the aforementioned power modules are also used to send power level to the control module, so that the control module can send the power level to the hollow optical cable junction box detection and management platform through the communication module. The hollow optical cable junction box detection and management platform is also used to generate a battery replacement prompt when the power level of any water vapor and dust detection device is lower than the power level threshold (such as lower than 20%), so as to remind maintenance personnel to replace the battery.

[0048] Thus, through the detailed architecture of the auxiliary detection system for fault location in hollow optical cables described above, this invention achieves proactive monitoring and accurate fault diagnosis of environmentally sensitive factors in hollow optical cables by deploying moisture and dust detection devices in each splice box of the hollow optical cable and combining them with a hollow optical cable splice box detection management platform. Specifically, addressing the pain point of hollow optical cables being highly sensitive to moisture and dust, and the difficulty of accurate fault location by traditional OTDRs, this invention utilizes real-time collected moisture and dust data, combined with signal reception power and historical detection data for comprehensive analysis. This effectively distinguishes abnormal environmental conditions within different splice boxes, thereby accurately identifying the specific location of the fault and solving the problem of traditional detection methods failing. Therefore, this invention provides an auxiliary judgment and location technology for faults in hollow optical cables caused by moisture and dust, improving maintenance efficiency and reducing hollow optical cable faults. This solution provides reliable operation and maintenance support for the engineering application of hollow optical cables in low-latency, high-bandwidth scenarios, improving the availability and maintenance efficiency of hollow optical cables.
