[0002] Optical cable route identification technology is usually used to accurately locate and track the path of optical cables, which is crucial for maintenance and repair. Accurate optical cable route identification can avoid damage to optical cables during construction or excavation, ensure network stability, and reduce service interruptions. It can also improve construction efficiency and save time and cost required for construction.

[0003] Existing optical cable route identification equipment requires on-site personnel to knock on the ground a specified number of times according to the settings before the equipment can identify the knocking location. If the signal strength and frequency of the knocking do not meet the requirements, it is easy to cause misjudgment. In addition, when the optical cable is long and the test range is large, it is necessary to observe the knocking signal of the equipment with human eyes and knock repeatedly to narrow the range. This type of equipment requires manual knocking, and the strength and frequency are not easy to control, unless the performance of the equipment is improved and a large number of knocking samples are collected to compensate for the uncertainty of manual knocking through algorithms. However, this method will undoubtedly increase the cost of the equipment, and it will take time to collect a large amount of data for training, which will increase a lot of manpower and material costs.

[0004] Therefore, it is necessary to propose an automatic tapping device and system for optical cable route identification, which can remotely control and adjust parameters such as tapping frequency and tapping force for optical cables of different lengths and depths, improve test accuracy, simplify the operation process, narrow the range and automatically identify the tapping position of optical cables with a large range and long length, and improve the work efficiency of optical cable route identification.

[0040] Figure 3 This is a structural schematic diagram of an embodiment of an optical cable identification host provided by the present invention. DETAILED DESCRIPTION

[0041] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0042] The present invention provides an automatic tapping device, system and computer-readable storage device for optical cable route identification, which are respectively described below.

[0043] Combination Figure 1 As shown, a specific embodiment of the present invention discloses an automatic knocking device for optical cable route identification, comprising a knocking module 101, a control module 102 and a wireless receiving module 103 connected in sequence;

[0044] The knocking module 101 is used to set knocking parameters according to the control instructions of the control module 102, and automatically knock the ground where the optical cable to be tested is laid;

[0045] The control module 102 is used to determine the default parameters of the knocking module according to the test requirements of the optical cable to be tested, and is also used to obtain the adjustment parameters sent by the wireless receiving module 103, determine the knocking parameters based on the default parameters and the adjustment parameters, and send a control instruction to the knocking module 101;

[0046] The wireless receiving module 103 is used to receive and analyze the parameter adjustment instructions sent by the host computer, obtain the adjustment parameters, and send the adjustment parameters to the control module 102 .

[0047] Compared with the prior art, the automatic tapping device for optical cable route identification provided in this embodiment cooperates with the wireless receiving module through the control module, and sets the tapping parameters according to the test requirements of the optical cable to be tested and the parameter adjustment instructions sent by the host computer. The tapping module automatically taps the ground on which the optical cable to be tested is laid based on the tapping parameters. The tapping device provided in this embodiment has a high degree of automation, does not require manual tapping, avoids errors caused by human factors, and improves the test accuracy; it is easy to operate, and the equipment can automatically adjust the tapping parameters without frequent manual intervention; it can be remotely controlled: control instructions and setting parameters are received through the wireless receiving module, remote control and parameter adjustment are realized, and the operation process is further simplified. This device is particularly suitable for testing optical cables of different lengths and depths. By adjusting the tapping force and frequency, it can adapt to different test environments and automatically identify the tapping position, thereby narrowing the test range and improving work efficiency.

[0048] As a preferred embodiment, the tapping parameters at least include tapping frequency and tapping intensity.

[0049] The periodicity and clarity of the signal can be adjusted by the tapping frequency to help distinguish different features or locations of the optical cable. The vibration intensity can be changed by the tapping force to ensure that the signal can be accurately detected, so that the optical cable identification host can accurately receive and analyze the vibration response.

[0050] For optical cables with different buried depths or different structures, the control module has preset corresponding default tapping frequencies and tapping forces. The preset default parameters reduce the need for manual intervention. Operators can directly use the default settings for testing, shortening the test preparation time and making the overall test process more efficient. The default parameters are stored in the control module. After a large number of scene tests, the default frequency and force selection provided for different scenes are selected. The tapping state of the tapping module is controlled by the controller to meet the test requirements of different scenes.

[0051] When the optical cable identification host fails to identify the knocking position or other special situations (such as environmental interference, optical cable damage or failure, etc.), the optical cable identification host will send parameter adjustment instructions to modify the default parameters to adapt to the differentiated needs of optical cable route identification, thereby improving the accuracy of identification.

[0052] Furthermore, in addition to the tapping frequency and tapping force, in some embodiments, the tapping parameters also include tapping duration (affecting the intensity and distribution of the vibration signal), tapping interval (the time interval between continuous tapping, affecting the periodicity and signal-to-noise ratio of the signal), tapping mode (the method or rhythm of tapping, such as single tapping, repeated tapping, random tapping, etc.), and tapping direction (the angle or direction of tapping, which may affect the signal propagation method and detection effect).

[0053] As a preferred embodiment, the knocking module adopts a mechanical knocking module or an electric knocking module.

[0054] The mechanical knocking module produces physical knocking action through mechanical devices (such as springs, levers or hammers). It has the advantages of simple structure, good durability and low maintenance cost. However, mechanical knocking may produce loud noise and sometimes requires manual adjustment by the operator.

[0055] Electric knocking modules usually use electric drive devices (such as electric vibrators, servo motors or stepper motors) to generate knocking movements, and use sensors to monitor and adjust the knocking force and frequency in real time. They have the advantages of good precision, high degree of automation and low noise, but electric knocking modules are more expensive and daily maintenance is more complicated than mechanical knocking modules.

[0056] In practice, the type of knocking module can be selected according to application scenarios and requirements.

[0057] See also Figure 2 , the embodiment of the present invention also provides an automatic tapping system 200 for optical cable route identification, including an automatic tapping device 201, a mobile terminal 202 and an optical cable identification host 203 connected in sequence;

[0058] The automatic tapping device 201 adopts the automatic tapping device for optical cable route identification described in any of the above technical solutions, which is used to determine the tapping parameters according to the test requirements of the optical cable to be tested and the parameter adjustment instructions sent by the host computer, and automatically tap the ground where the optical cable to be tested is laid;

[0059] The mobile terminal 202 is installed with a control program for receiving a parameter adjustment instruction and sending the parameter adjustment instruction to the automatic tapping device;

[0060] The optical cable identification host 203 is used to receive the vibration signal generated by the automatic tapping device 201 through tapping, and process and analyze the vibration signal to identify the tapping position.

[0061] The working principle of this system is as follows: the automatic knocking device knocks the ground at a preset frequency and strength, and the vibration signal generated by the knocking is received by the optical cable routing recognition host, and processed and analyzed to identify the knocking position. When the position is not identified, the optical cable routing recognition host issues a parameter adjustment instruction through analysis, and the on-site staff receives the instruction through the control program APP of the mobile terminal. The APP sends the instruction wirelessly to the automatic knocking device, and the automatic knocking device automatically adjusts the knocking parameters after receiving the instruction to accurately locate the optical cable knocking position.

[0062] As a preferred embodiment, the mobile terminal sends the instruction to the automatic tapping device via Bluetooth.

[0063] Bluetooth communication reduces electromagnetic interference that may be caused by cable connections, ensuring more stable and accurate operation, while eliminating the need for physical connections, making operation more flexible and convenient. Operators can remotely control the tapping device at different locations within the Bluetooth range without manual tapping, which is suitable for long-distance and large-scale test scenarios.

[0064] It should be noted here that the parameter adjustment instructions received by the mobile terminal can be sent by the host computer (such as the optical cable identification host), or can be input and set by the operator in the APP. The on-site staff can set the tapping parameters according to the test scenario, and send the instructions containing the adjusted tapping parameters to the automatic tapping device through the APP program. The automatic tapping device receives and parses the instructions through the wireless receiving module, and then sends them to the control module, which adjusts the tapping state of the tapping module accordingly.

[0065] As a preferred embodiment, Figure 3 As shown, the optical cable identification host 203 includes a signal acquisition unit 301, an analysis unit 302 and a positioning unit 303 connected in sequence;

[0066] The signal acquisition unit 301 is used to obtain the vibration signal generated by the automatic knocking device;

[0067] The analysis unit 302 is used to convert the vibration signal into a frequency domain data array, perform frequency screening on the frequency domain data array, determine the frequency domain data in the array that matches the knocking frequency, and obtain matching frequency domain data;

[0068] The positioning unit 303 is used to calculate the optical cable position corresponding to the knocking point according to the matching frequency domain data.

[0069] As a preferred embodiment, the positioning unit locates the optical cable position corresponding to the knocking point calculated according to the matching frequency domain data, including:

[0070] The position of the knocking point in the optical cable is calculated based on the subscript of the matching frequency domain data in the array, the fiber refractive index, the sampling rate and the speed of light. The calculation formula is:

[0071] L=(c / (2n*Fs))*P

[0072] Wherein, c represents the speed of light, n represents the refractive index of the optical fiber, Fs represents the sampling rate, and P represents the subscript of the matching frequency domain data in the array.

[0073] As a preferred embodiment, the positioning unit further includes an area screening module;

[0074] The area screening module is used to narrow the range according to the duration of the knocking frequency at each knocking position when there is more than one knocking position matching the knocking frequency, and determine a unique knocking position.

[0075] Specifically, a duration threshold is set to filter out matching locations with longer durations. If the duration exceeds the threshold, it is considered a valid location. Sort the recorded matching locations by duration and select the location with the longest duration. If there are multiple locations with similar durations, other features of these locations can be further analyzed to determine unique values ​​by analyzing the duration of the matching locations and their changes. Weighted average or the most frequently occurring locations can be used to narrow the scope and obtain unique values.

[0076] Among them, the features that can be analyzed include: position stability (the range of amplitude changes over a period of time), signal strength (signal strength or clarity of the matching position), frequency accuracy (the matching accuracy of the position with the preset frequency) and vibration pattern (whether the vibration or response pattern of the position is consistent).

[0077] As a preferred embodiment, the analysis unit further includes an adjustment calculation module;

[0078] The adjustment calculation module is used to determine the knocking parameters that need to be adjusted according to the vibration signal and the buried depth and structural characteristics of the optical cable to be tested when the positioning unit fails to identify the knocking position, and generate parameter adjustment instructions according to the knocking parameters.

[0079] As a specific embodiment, if the optical cable is buried deep, such as a depth greater than 3 meters, and the coupling degree is poor, such as the optical cable is suspended inside the pipe or is wrapped with an additional layer, it is necessary to set the acceleration through the device according to the actual situation to increase the knocking force, thereby improving the accuracy and efficiency of identification.

[0080] In some embodiments, the optical cable identification host further includes a command sending unit;

[0081] The instruction sending unit is used to obtain the parameter adjustment instruction of the adjustment calculation module, upload the parameter adjustment instruction, and send it to the control program of the mobile terminal module.

[0082] The present invention provides an automatic tapping device and system for optical cable route identification, wherein:

[0083] The device of the present invention cooperates with the wireless receiving module through the control module, sets the tapping parameters according to the test requirements of the optical cable to be tested and the parameter adjustment instructions sent by the host computer, and the tapping module automatically taps the ground where the optical cable to be tested is laid based on the tapping parameters.

[0084] The system of the present invention uses an automatic tapping device, a mobile terminal, and an optical cable route identification host for use. The automatic tapping device sets a fixed frequency and strength to automatically tap the ground on which the optical cable is laid. The on-site staff transmits the control instructions of the optical cable route identification host to the automatic tapping device through the mobile terminal, and adjusts the tapping parameters so that the tapping parameters such as the tapping strength and frequency of the automatic tapping device are adapted to different test environments, thereby improving the test accuracy and enhancing the adaptability of the system.
