[0002] In existing technologies, the method for tracing optical cable routes involves field workers locating cable manholes along the general route of the cable, tapping all cables to vibrate the optical fibers, and notifying the equipment room staff. When an OTDR (Optical Time Domain Reflectometer) detects an abnormal loss point in the cable, it is confirmed as the cable under test. The location of each cable manhole is then confirmed to assemble the entire optical cable route. This method suffers from problems such as large workload, slow tracing speed, need for manual intervention, and susceptibility to environmental interference. Therefore, a rapid optical cable route tracing method that requires no manual intervention and offers high tracing speed is needed. Summary of the Invention

[0039] In response to existing methods for determining optical cable routes, this application addresses the issue by placing an exciter capable of emitting specific voice content on the optical cable well. The location of the exciter is obtained by analyzing the vibration characteristics in the optical cable, thereby determining the optical cable route. This approach ensures the positioning accuracy of the optical cable well, improves the accuracy of the optical cable route determination results, and increases the efficiency of optical cable route determination.

It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device 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 devices.

[0041] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 A schematic diagram of the first embodiment of the optical cable routing determination method provided by this invention is shown. The method specifically includes the following steps:

[0042] 101. The server sends start commands to each exciter in sequence.

[0043] The system acquires device information from the exciters and generates start commands for the exciters to be started according to a preset format based on the device and location information. It extracts the exciter serial number from each exciter in the exciter list and generates corresponding start commands based on these serial numbers. These start commands are then sent sequentially to each exciter via wireless IoT, according to the distance between the exciter and the optical fiber sensing device. The start commands include an activation sub-command and a location sub-command. The optical sensing system includes an optical fiber sensing device, at least one exciter, and a server. The server connects to the optical fiber sensing device via the Internet and to the at least one exciter via IoT. Each exciter corresponds one-to-one with a communication optical fiber well, meaning the exciter is placed under the well cover. In this case, the location information sent by the exciter's positioning module is both the exciter's location information and the communication optical fiber well's location information. Before sending commands, the server needs to sequentially execute initialization and configuration processes, including starting and preparing various services, loading the operating system, and configuring the network, to ensure the server can operate normally. In the remote management system, the server can send commands to each exciter via remote access, enabling remote control and management of the server. The server generates activation sub-instructions for each exciter based on their location information and distance from the optical cable sensing device. These activation sub-instructions instruct the exciter to activate its voice playback module and play voice messages. The exciter's positioning module is activated when the exciter is installed on the manhole cover through which the optical cable passes. In other words, the exciter continuously generates location information from the moment it is installed on the manhole cover. Upon receiving this location information, the server obtains the exciter's location information, generates a position sub-instruction, and generates a start command based on the activation and position sub-instructions. Finally, the start command is sent to the exciters sequentially according to the exciter list via wireless IoT.

[0044] 102. The exciter converts its device information and location information into voice information based on the start command, and generates sound waves based on the voice information. The sound waves act on the optical cable in the corresponding communication optical cable well, so that the optical cable forms a reflected light signal.

[0045] An exciter consists of a wireless IoT module, a signal generator, and a vibration device. It is a device that emits a sound of a specific frequency according to the IoT command it receives. It is used to convert the input signal (usually a baseband signal) into an excitation signal. The excitation signal is emitted as sound through a speaker or other audio output device. In the fields of speech synthesis and audio processing, the role of the exciter is to drive the speech signal to generate specific speech content. Specifically, the text to be converted into speech is first input into a TTS (Text-to-Speech) system, which converts the text into basic acoustic features of speech, such as phonemes, pitch, and duration. Then, a pre-trained acoustic model is used to map the acoustic features of the text to parameters for synthesized speech. These parameters describe the temporal changes of the speech signal and the spectral characteristics of the sound. During speech synthesis, the parameters generated by the acoustic model need to be combined with an exciter to produce an excitation signal. Different types of exciter algorithms can produce different styles of speech, such as those based on excitation impulses or noise sources. Finally, the excitation signal is combined with the parameters generated by the acoustic model to generate the final speech waveform through a speech synthesis engine. This speech waveform can be directly sent to a speaker or other audio device to emit specific speech content.

[0046] Furthermore, the process of converting the device information and location information of the exciter into speech information and playing it to generate sound waves can be divided into the following steps: The server or computer sends a start command to each exciter. The start command is a control signal used to inform the exciter to start performing a certain action or collecting information. When the exciter receives the start command, it performs the corresponding action according to the command, including acquiring its own device information and location information. The device information includes the exciter's serial number, model, hardware specifications, working status, etc., and the location information includes the exciter's specific location, coordinates, etc. After acquiring the device information and location information, the exciter converts this information into text form. This process involves textification, encoding, and formatting. For example, the exciter may synthesize the device information and location information into a descriptive text. Using text-to-speech technology, the above text information is converted into a corresponding speech signal. The TTS system converts the text into acoustic features and excitation signals to drive the synthesized speech. Finally, the synthesized speech signal is transmitted to a speaker or other audio device, and sound waves are generated by playing it, thus conveying the exciter's device information and location information in the form of sound.

[0047] 103. The optical cable sensing device receives the reflected light signal transmitted by the target optical cable, and extracts the target voice information of the exciter acting on the target optical cable and the optical cable distance information corresponding to the target voice information from the reflected light signal; based on the target voice information, it obtains the optical cable well location information through which the target optical cable passes, and sends the optical cable well location information and optical cable distance information to the server.

[0048] Feature extraction for vibration signals mainly relies on time-domain and frequency-domain feature extraction or wavelet analysis. Time-domain features are divided into short-time features and long-time sequence features. Short-time features extract the envelope information of the vibration signal, primarily including rise time, fall time, and peak amplitude. Long-time sequence features represent the signal's time-series changes over a longer period, mainly including the number of zero-crossings, the number of vibration segments, and the average peak amplitude.

[0049] 104. The server obtains the optical cable route based on the location of each optical cable well.

[0050] The server typically obtains fiber optic cable routes based on the locations of each fiber optic cable manhole through network planning and GIS (Geographic Information System) technology. Specifically, the process begins by collecting data on the locations of the fiber optic cable manholes. This data may include the manhole's geographic coordinates (latitude and longitude or other location information), unique identifier, and manhole cover status. This information can be obtained through on-site surveys, GPS positioning, and digital maps. In this solution, the manhole location information comes from data uploaded by fiber optic cable sensing devices. Based on the existing manhole locations, a fiber optic cable routing plan is developed, determining the route and connection methods. This planning may involve connections between multiple manholes to build a complete network communication link. The manhole locations are then marked on a GIS map to obtain the geographical relationships between them, and the routing plan is optimized. After determining the manhole locations and the cable routing plan, a routing algorithm based on network topology, transmission rate, and latency is used to find the optimal fiber optic cable path from one location to another.

[0051] Ideally, the received fiber optic manhole locations can be stored on a server or in a database for subsequent queries and processing. Since geographical information may change over time—new fiber optic manholes may be added or the locations of existing ones may change—the fiber optic manhole location information stored on the server needs to be updated and maintained regularly to ensure the accuracy of network planning. Even better, a fiber optic cable detector (or line tracker) can be used. An electromagnetic signal is injected into the fiber optic cable, and a receiver on the ground searches for this signal to detect the cable's specific location and path.

[0052] In this solution, the exciter converts its device and location information into voice information based on the start command, and plays it to generate sound waves. These sound waves act on the optical cable to cause deformation. The optical cable sensing device receives the reflected light signal and obtains the location of the optical cable well based on the vibration information. The server obtains the optical cable route based on the location of each optical cable well, ensuring the positioning accuracy of the optical cable well and improving the accuracy of the optical cable route determination result.

[0053] Please see Figure 2 A schematic diagram of a second embodiment of the optical cable routing determination method provided by this invention, the method specifically includes the following steps:

[0054] 201. The server activates the positioning module of each exciter and sorts each exciter according to its distance from the optical cable sensing device set at one end of the optical cable, thus obtaining the exciter list of the optical cable.

[0055] Please see Figure 3 The schematic diagram of the optical sensing system provided in this embodiment of the invention includes a server system for recording manhole cover vibration information, location, and load-bearing system management software; an optical cable sensing device that integrates a narrow-linewidth laser generator, data acquisition, signal processing, and data transmission functions; this device can inject laser pulses into the optical cable and then detect the vibration of the entire optical cable based on the Rayleigh scattering effect generated in the optical cable; and a manhole cover exciter (hereinafter referred to as the exciter), which is a device that includes a wireless Internet of Things module, a signal generator, and a vibration device, and can emit a sound of a specific frequency according to the received Internet of Things instructions.

[0056] Please see Figure 4 The flowchart of the optical cable route determination method provided in this embodiment of the invention is shown below. For step 1, the operator goes to the manholes that the optical cable may pass through, opens the manhole cover, and places the exciter into the optical cable manhole. Each exciter corresponds one-to-one with each communication optical cable manhole. The exciter is required to have a GPS positioning module and a voice playback module.

[0057] For step 2, the server system sequentially activates the manhole cover actuators via the Internet of Things (IoT): the server sends commands to the actuators via wireless IoT to generate opening and closing sounds for the manhole cover actuators; the command format is as follows:

[0058]

[0059] For step 3, the manhole cover actuator plays voice information (the voice information includes the current actuator's ID and GPS information): Upon receiving the command, the actuator can turn the sound off or on, and adjust the volume accordingly. Simultaneously, the voice source can be selected (e.g., a male voice with the message "Current actuator ID is 7666, coordinates are latitude xxx, longitude yyy").

[0060] For step 4, the optical cable sensing device senses the existence of specific vibrations in the optical cable and saves the vibration information: the optical cable sensing device emits laser pulses into the optical cable, detects weak reflected light through Rayleigh scattering effect, and obtains the vibration waveform of each point on the optical cable through photoelectric conversion, electrical signal amplification, analog-to-digital conversion, data acquisition, signal processing and other operations, and saves the current vibration information and inputs it into the back-end voice module for recognition and processing.

[0061] For step 5, speech recognition: parsing the exciter's ID / GPS location information: This module uses the speech recognition module on the sensing device to convert the vibration of the optical cable into sound, and then extracts the text from this speech. This directly obtains the corresponding exciter ID and GPS location information.

[0062] For step 6, the fiber optic sensing device reports the sensing results to the server via the Internet: The fiber optic sensing device uploads the current detection results of the fiber optic cable to the server via wired / wireless Internet. The detection results include the detection result judgment and the corresponding location information, in the following format:

[0063]

[0064] This data frame indicates the exciter number at the location of the optical cable;

[0065] For step 7, the server system records the number of the manhole cover exciter and the upload result of the optical cable sensor: the server can determine the current optical cable route based on the currently activated exciter number and the upload result of the optical cable sensor.

[0066] For step 8, after the server system completes the traversal, it completes the optical cable route based on the results returned by the exciter and the distance: After the server completes the activation of all exciters in sequence, it can obtain the manhole cover information that the optical cable passes through, that is, it can draw the optical cable route map based on the coordinate information of the exciter.

[0067] 202. The server generates an activation sub-instruction for the exciter to be started based on the exciter sequence number, generates a position sub-instruction based on the exciter's position information, and generates a start instruction based on the activation sub-instruction and the position sub-instruction.

[0068] 203. The server sends the start command to the exciter in sequence according to the exciter list via wireless IoT.

[0069] The actuator list refers to an actuator queue sorted by distance from the optical cable sensing device. Further, the actuator queue can also be based on the expected route of the optical cable determined by a preset path selection model.

[0070] 204. The exciter starts the voice playback module based on the start sub-command and configures the voice playback module based on the playback configuration information to obtain the voice playback template.

[0071] In theory, the structure of an exciter capable of receiving commands from a server and emitting specific speech involves the following components: a control interface capable of receiving server commands, which can be a physical interface (e.g., serial port, USB) or a network interface (e.g., Ethernet, Wi-Fi). The exciter described in this solution has a network interface, enabling it to receive start commands from the server via wireless IoT. The exciter needs to integrate a speech synthesizer or TTS engine to convert the server-sent text commands into speech. The exciter needs a management center capable of acquiring its own device and location information to generate relevant speech content. After receiving commands from the server, the exciter transmits the commands to control software or a service through the control interface. The control software generates specific speech content based on the information in the commands, such as device and location information, and specific speech synthesis logic. The generated speech content is played through a built-in speaker or an external audio device connected to the exciter, thus emitting specific speech; that is, the exciter needs suitable hardware to support audio output. The exciter receives the start command, extracts its device information based on the start command, and activates its speech playback module. The playback configuration information can be preset in the exciter or configured by the server. The exciter can be pre-configured for the voice playback module, including volume settings, playback voice segments, and playback sounds. For example, the volume setting is used to indicate the size of the exciter's playback volume. In order for the optical cable near the exciter to be able to sense the sound wave effect, the volume setting has a minimum safe volume, and the volume of the exciter must exceed the minimum safe volume.

[0072] 205. Match the device information and location information of the exciter to the voice playback template, generate voice information and play it to produce sound waves.

[0073] This step involves converting the location information obtained by the exciter's positioning module into keyword-based data. Depending on the data format and coordinate system, this keyword-based location information needs to be converted into latitude and longitude coordinates. Specifically, if the location information is a place name or address, a geocoding service can be used to call the geocoding API to convert it into latitude and longitude. If the location information uses a different coordinate system, coordinate system parameters and coordinate transformation algorithms can be used to convert it into latitude and longitude. If the location information uses GPS coordinates, it is usually already in latitude and longitude format and does not require additional conversion. If the location information is represented by pixel coordinates in an image, image processing and map calibration techniques are used to combine map information and calibration point coordinates to convert pixel coordinates to latitude and longitude coordinates. The template for voice information is exciter information + location information. The exciter information is the exciter's ID, and the location information is the exciter's geographic location (latitude and longitude coordinates).

[0074] 206. The optical fiber sensing device receives reflected light signals based on sound waves, processes the signals to obtain vibration information, analyzes the vibration information, and obtains the analysis results.

[0075] The optical cable sensing device described in this solution is an optical cable sensing device that integrates functions such as narrow linewidth laser generator, data acquisition, signal processing, and data transmission. This device can inject laser pulses into the optical cable and then detect the vibration of the entire optical cable based on the Rayleigh scattering effect generated in the optical cable.

[0076] Optical fiber sensing devices extract vibration information from reflected light in optical fibers using optical fiber sensing technology. Utilizing the characteristics of optical fibers, they acquire information about physical quantities in the environment by measuring changes in light intensity, phase, or frequency. The devices are installed on the optical fiber where vibration needs to be monitored, recording how specific properties of light change with vibration. Vibration causes minute changes in the Bragg grating or reflection position in the optical fiber, thus altering the properties of the light. The monitoring system reads the reflected light signal in real time, analyzes the vibration information within it, and obtains the characteristics and amplitude of the vibration by measuring changes in wavelength or frequency, or by measuring the time delay of the reflected light signal and measuring changes in that time delay to obtain vibration information.

[0077] Better yet, the vibration information obtained from optical signals is usually raw data, which requires further data processing and analysis, involving steps such as filtering, denoising, and signal processing, to extract useful vibration features.

[0078] 207. The optical cable sensing device identifies the vibration information based on the analysis results, determines the corresponding voice information, extracts the exciter position information from the voice information to obtain the optical cable well position, and uploads the optical cable well position to the server.

[0079] 208. The server obtains the optical cable route based on the location of each optical cable well.

[0080] In this scheme, obtaining the optical cable route based on the location of each optical cable well means determining the transmission path of the optical cable from the source node to the target node through an algorithm based on the network topology, equipment status, and other relevant information.

[0081] Dynamic routing protocols use routing algorithms to select the optimal path. Common routing algorithms include distance vector, link state, and path vector algorithms. These algorithms select the best route based on different metrics and strategies, such as shortest path, fastest path, or most reliable path.

[0082] Determining fiber optic cable routes is typically a network planning process involving selecting appropriate paths from multiple points to connect them to meet specific network communication needs. This includes: identifying the starting and destination points, where the starting point is the location of the fiber optic sensing equipment, and the intermediate and destination points are the locations of the fiber optic manholes; analyzing the network topology to understand the physical connections between points, including the layout and connections of the fiber optic manholes; selecting a suitable path selection algorithm to determine the optimal path from the starting point to the destination, common algorithms including shortest path algorithms (such as Dijkstra's algorithm and Bellman-Ford algorithm) and minimum spanning tree algorithms (such as Prim's algorithm and Kruskal's algorithm); and considering potential constraints in the actual network during route determination, such as fiber optic cable capacity limitations, equipment bandwidth limitations, geographical conditions, and security requirements.

[0083] This solution uses an exciter that can emit specific voice content placed on the fiber optic cable well to analyze the vibration characteristics in the fiber optic cable to determine the location of the exciter, thereby determining the fiber optic cable route. This ensures the positioning accuracy of the fiber optic cable well, improves the accuracy of the fiber optic cable route determination results, and increases the speed of fiber optic cable route investigation.
