[0025] On the one hand, the embodiment of the present application provides a method for monitoring the protection of optical cables from external force damage in combination with sound source monitoring, such as Figure 2 As shown, the method at least includes, S1.

The monitoring equipment can be a device that supports audio monitoring and is used to monitor the environment and audio conditions near the optical cable.

[0026] Illustratively, in step S1 of this embodiment, the real-time monitoring of the optical cable may be based solely on real-time monitoring of audio, or may be combined with other monitoring methods, such as real-time monitoring based on vibration.

[0027] During specific implementation, when a monitoring device that supports audio monitoring is used to realize real-time monitoring of the corresponding optical cable segment, the device that supports audio monitoring starts the audio monitoring service. When an abnormal audio signal is detected in real time, the monitoring device obtains and saves the abnormal audio signal, thereby realizing automatic collection and preservation of the abnormal audio signal, ensuring the real-time and reliability of optical cable monitoring, and facilitating subsequent secondary investigation of optical cable abnormalities.

[0028] In a preferred embodiment, the monitoring device supporting audio monitoring further supports saving audio signals monitored within a custom time period.

[0029] When real-time monitoring is performed in combination with other monitoring methods, the other monitoring methods can be used as the main monitoring method. When monitoring is performed through the main monitoring method and an abnormal situation is found, the abnormal audio signal can be collected by enabling the audio monitoring service, so as to further process the abnormal audio signal.

[0030] When real-time monitoring is performed in combination with other monitoring methods, other monitoring methods can also be used as auxiliary monitoring methods, and the audio-based monitoring method can be used as the main monitoring method. At this time, when monitoring is performed through the audio-based monitoring method and an abnormal situation is found, the abnormal audio signal can be saved and processed. Other monitoring methods can be used to assist in analyzing the abnormal situation of the optical cable. The specific auxiliary analysis is not limited here.

[0031] In a preferred embodiment, after obtaining the real-time monitoring situation, the real-time monitoring situation can also be displayed. Specifically, the monitoring situation of different monitoring devices can be displayed, including the optical cables of each line and the audio signals around them under different monitoring devices. Multiple monitoring devices are used to monitor different lines to comprehensively display the working conditions of each line and each optical cable.

[0032] In this embodiment, when an abnormal audio signal appears in the real-time monitoring situation, the abnormal audio signal and the corresponding abnormal audio signal waveform are obtained. The specific process may include: A decibel threshold is preset, and an audio signal with an audio decibel greater than the decibel threshold is considered an abnormal audio signal; At the same time, the starting point of the abnormal audio signal is used as the first time, and the ending point is used as the second time, and the first time of the same abnormal audio signal is earlier than the second time in terms of time; When an abnormal audio signal is detected around the optical cable, the abnormal audio signal around the optical cable and the corresponding first time and second time are obtained, and the abnormal audio signal is analyzed to obtain a corresponding abnormal audio signal waveform.

[0033] In this embodiment, step S3 obtains the sound source type of the abnormal audio signal by analyzing the abnormal audio signal waveform. In combination with step S4, the alarm type can be obtained according to the sound source type. Exemplarily, the sound source types include excavator sound source, pile driver sound source, external break ambient sound, leakage ambient sound, etc. Exemplarily, the alarm type includes one or more of external break, construction, false alarm or leakage. Exemplarily, the process of obtaining the sound source type by analyzing the abnormal audio signal waveform in this embodiment is as follows: pre-acquire audio waveforms of several known sound source types, such as audio waveforms corresponding to ambient noise caused by construction activities such as excavators and pile drivers during construction, or audio waveforms corresponding to ambient noise generated by optical fiber faults such as external break and leakage. Based on the pre-acquired audio waveforms of known sound source types, combined with an artificial intelligence model, training is performed to obtain an artificial intelligence model for sound source type identification, thereby achieving accurate identification of sound sources including construction activities, optical fiber faults, etc. The artificial intelligence model can be implemented based on a neural network.

[0034] The alarm type is obtained based on the sound source type of the abnormal audio signal, the abnormal audio signal is processed in advance, and the possible sound source of the abnormal audio signal is analyzed to improve the accuracy of the alarm judgment. At the same time, the alarm information can be classified based on the alarm type to improve the processing efficiency of the alarm information.

[0035] Exemplarily, the external damage includes but is not limited to new well fracturing, landslide external damage and earthquake external damage; the leakage may be leakage of the corresponding oil pipe when the optical cable is a companion optical fiber, and the construction includes but is not limited to excavator construction, pile driver construction, shield machine construction, drilling construction and underground operation construction in the environment where the optical cable is located. The judgment of alarm types such as external damage, construction, and leakage can be achieved by analyzing the abnormal audio signal waveform. Furthermore, when this embodiment can also be combined with other monitoring methods besides audio monitoring, other monitoring methods can also be used to monitor the fault of the optical cable accessories, thereby obtaining the alarm type corresponding to the fault of the optical cable accessories, and the optical cable accessories fault includes but is not limited to joint loss fault, fiber break fault, and poor contact fault.

[0036] In a specific implementation process, the abnormal optical cable segment information in step S5 of this embodiment may include the route of the abnormal optical cable, the optical cable segment number, and the position and direction of the optical cable segment on the map.

[0037] In step S6 of this embodiment, based on the alarm type, the abnormal optical cable segment information, the abnormal audio signal and the corresponding abnormal audio signal waveform, an alarm message is generated. Exemplarily, the alarm information includes one or more of the alarm type, alarm location, alarm number, alarm time, duration, abnormal audio signal, and corresponding alarm waveform, wherein: Alarm location: The alarm location is obtained according to the abnormal optical cable segment information, and the alarm location includes the route of the abnormal optical cable segment and the location information on the map; Alarm time and duration: obtaining the alarm time and duration according to the first time and the second time; Alarm waveform: obtained based on the abnormal audio signal waveform, used for subsequent analysis to obtain the sound source type, and then obtain the alarm type. The alarm waveform is displayed in the alarm information of the real-time monitoring list to assist operators in judging the situation near the abnormal optical cable section.

[0038] In this embodiment, the alarm information is divided into two states: verified and unverified. The confirmed alarm information state is verified. For unverified alarm information, in this embodiment, the following processing can be selected: Alarm confirmation: select the unverified alarm information, confirm the content of the unverified alarm information, update the alarm information status to verified, and delete the unverified alarm information from the unverified alarm list; in the specific implementation process, in the process of confirming the content of the unverified alarm information, if it is determined that the unverified alarm information is a real alarm or alarm information that requires attention or further processing, further processing methods can be used to handle the unverified alarm information.

[0039] During the specific implementation process, the all alarm confirmation function can be used to confirm the content of all unverified alarm information and then update the status of all alarm information to verified.

[0040] And / or, block confirmation: Select the unverified alarm information, block the alarm location corresponding to the unverified alarm information, and update the status of the unverified alarm information to verified. Block confirmation can block unverified alarm information, reducing the number of times such alarm information is generated, which helps to handle alarm information that needs to be blocked in some special circumstances. Blocked alarm information can be displayed in a preset block area function, making it easier to release specific alarm information from the block area later.

[0041] Construction confirmation: When the alarm type is construction, the real-time construction information of the corresponding alarm location is obtained according to the corresponding alarm information, and the status of the alarm information is updated to verified.

[0042] In a preferred embodiment, construction monitoring can be performed for the optical cable segment whose alarm type is construction, and the specific implementation method is as follows: After obtaining the real-time construction information corresponding to the alarm location, the unverified alarm information is further confirmed according to the real-time construction information to obtain a construction monitoring signal, and a new construction monitoring task is added to the optical cable segment corresponding to the alarm location according to the construction monitoring signal; Specifically, when the alarm type is construction, further construction confirmation can be performed based on the real-time construction information to determine that the corresponding optical cable segment is in a construction environment. A construction monitoring signal is then generated, and a construction monitoring task is added to the optical cable segment corresponding to the alarm location based on the construction monitoring signal. In specific implementation, construction monitoring can be performed on the corresponding optical cable segment based on the construction monitoring task, thereby focusing on monitoring the optical cable segment in the construction environment.

[0043] During the specific implementation process, construction monitoring tasks can also be generated by manual creation, selecting the optical cable segment that needs construction monitoring, generating a construction monitoring signal for the optical cable segment that needs construction monitoring, and adding a construction monitoring task to the optical cable segment that needs construction monitoring based on the construction monitoring signal.

[0044] The real-time construction information includes at least one or more of the following: construction route, construction name, construction starting point location, construction type, construction contact person and contact information, construction period, construction unit and corresponding contact information, construction period, site description, confirmation personnel, and confirmation time; In this embodiment, the historical monitoring status of the optical cable can also be included to display the monitoring records, specifically including: The monitoring data corresponding to the real-time monitoring situation is saved to obtain historical monitoring data, and the historical monitoring situation of the corresponding optical cable is displayed based on the saved historical monitoring data.

[0045] In a preferred embodiment, the historical monitoring situation may include the monitoring results of each optical cable line or optical cable segment on different dates, and the playable audio signal corresponding to the monitoring result. When a secondary check is performed on the optical cable abnormality subsequently, the monitoring situation and abnormal audio signal corresponding to the abnormal situation can be obtained by screening according to the date conditions, optical cable line conditions or optical cable segment conditions in the historical monitoring situation.

[0046] In a preferred embodiment, the real-time monitoring, historical monitoring and construction monitoring of the optical cable in this embodiment can be achieved in combination with a map, and the monitoring information and alarm information of the optical cable are displayed on the map in the form of icons, which makes it convenient for operators to process the alarm information according to the actual scenario, facilitates line planning, and improves the efficiency and accuracy of operations.
