Description

Technical Field

[0001] The present application relates to the technical field of submarine cable detection, and particularly to a submarine cable burial depth detection system, method, device, computer device, storage medium, and computer program product. Background Art

[0002] During the laying process of submarine cables (i.e., undersea cables), deep burial is generally adopted for protection. However, over time and due to factors such as external ocean current scouring, the burial depth (i.e., the buried depth) of the submarine cable will change. When the burial depth of the submarine cable continuously decreases and even the submarine cable is exposed on the seabed, the submarine cable is prone to external damage. Therefore, it is necessary to continuously detect the burial depth of the submarine cable.

[0003] In traditional technologies, an underwater robot equipped with a camera can be used to obtain the surrounding conditions of the submarine cable to determine the exposure situation of the submarine cable. In areas where no exposed submarine cable is photographed, a sonar is used to emit acoustic wave signals to determine the position of the submarine cable, and a magnetic field sensor is used to receive the magnetic field signals around the submarine cable to obtain the induced electromotive force in the magnetic field signals. According to the electromagnetic attenuation law, the burial depth of the submarine cable is determined. However, when using traditional technologies to detect the burial depth of submarine cables, multiple underwater devices need to be operated, which makes the operation of the submarine cable burial depth detection method complex.

[0060] Figure 1 An exemplary structural block diagram of a submarine cable burial depth detection system is shown, as Figure 1 shown, the submarine cable burial depth detection system includes a depth sounder 102, an acoustic signal generator 104, a data processing device 106 and a sensing optical fiber 108.

[0061] Among them, the depth sounder 102 is a water depth measuring instrument applicable to many waters such as rivers, lakes, reservoirs, waterways, port terminals, coastal areas, and deep seas. The depth sounder 102 can but is not limited to include any one of an echo sounder, a lift compensation depth sounder, a towed depth sounder, a multibeam depth sounder, and a dual-frequency depth sounder.

[0062] The acoustic signal generator 104 is an acoustic wave transmitting device capable of transmitting a tuned acoustic signal. In one example, the acoustic frequency of the acoustic signal generated by the acoustic signal generator 104 is between 400 Hz and 1000 Hz, and the acoustic intensity is above 160 dB. The acoustic signal transmitted by the acoustic signal generator 104 can penetrate the seabed and be received by the sensing optical fiber in the submarine cable. The acoustic signal generator 104 can be disposed in the same waterborne device as the depth sounder 102. For example, the acoustic signal generator 104 and the depth sounder 102 can be disposed at the bottom of the same ship.

[0063] The data processing device 106 is connected to the depth sounder 102, the acoustic signal generator 104, and the sensing optical fiber 108 disposed in the submarine cable. In one example, GPS devices (Global Positioning System) are deployed on the depth sounder 102, the acoustic signal generator 104, and the data processing device 106. The depth sounder 102 can communicate with the data processing device 106 through the GPS device, and the acoustic signal generator 104 can communicate with the data processing device 106 through the GPS device. In another example, the data processing device 106 is physically connected to the sensing optical fiber 108 disposed in the submarine cable on land, and can directly monitor the acoustic signals received by the sensing optical fiber.

[0064] The sensing optical fiber 108 can include, but is not limited to, any one of a passive access (i.e., no power supply required) submarine communication optical fiber and a submarine optical power fiber. In one embodiment, by using the passive access sensing optical fiber 108, the safety of the submarine cable burial depth detection system can be improved.

[0065] Specifically, the depth sounder 102 and the acoustic signal generator 104 are disposed in the same waterborne device. The depth sounder 102 is used to detect the seabed depth and send the seabed depth to the data processing device 106. The seabed depth can be the distance between the depth sounder 102 and the seabed. In one example, taking an echo sounder as an example, the process of the depth sounder 102 detecting the seabed depth is described as follows: The echo sounder emits acoustic waves and receives the acoustic waves reflected by the seabed, records the start time of the emitted acoustic waves and the end time of the received acoustic waves. Determine the first time difference between the start time and the end time. Determine the first propagation rate of the acoustic waves in the seabed according to the frequency of the acoustic waves. According to the first time difference and the first propagation rate, obtain the seabed depth.

[0066] The acoustic signal generator 104 is used to emit a first acoustic signal with a preset frequency to the sensing optical fiber 108, record the acoustic data of the first acoustic signal, and send the acoustic data to the data processing device 106. The acoustic data can include, but is not limited to, at least one of the emission time, emission position, and acoustic frequency of the first acoustic signal.

[0067] The data processing device 106 receives the seabed depth sent by the depth sounder 102 and the acoustic data sent by the acoustic signal generator 104, and monitors the acoustic signals received by the sensing optical fiber 108. Process the acoustic signals, determine the first acoustic signal from the acoustic signals, and obtain the reception time of the first acoustic signal. Perform arithmetic processing on the acoustic data and the reception time to determine the submarine cable depth. Perform arithmetic processing on the seabed depth and the submarine cable depth to generate the burial depth of the submarine cable. The submarine cable depth can be the distance between the acoustic signal generator 104 and the submarine cable.

[0068] The above submarine cable burial depth detection system sets a depth sounder and an acoustic signal generator in the same waterborne device, connects the depth sounder, the acoustic signal generator, the sensing optical fiber arranged in the submarine cable and the data processing device, receives the seabed depth emitted by the depth sounder and the acoustic data of the first acoustic signal sent by the acoustic signal generator through the data processing device, processes the acoustic signal received by the sensing optical fiber, determines the reception time of the first acoustic signal, determines the submarine cable depth according to the acoustic data and the reception time, and generates the burial depth of the submarine cable according to the seabed depth and the submarine cable depth; it can directly obtain the seabed depth and the submarine cable depth through the data communication between the depth sounder, the acoustic signal generator and the data processing device without operating multiple devices underwater, determine the burial depth of the submarine cable, and thus make the operation of the submarine cable burial depth detection system simple. In addition, since the submarine cable burial depth detection system provided in this application does not need to operate multiple devices underwater, the cost of the submarine cable burial depth detection system is reduced.

[0069] In one embodiment, the depth sounder 102 is further configured to detect first position information corresponding to the seabed depth. The acoustic data carries second position information corresponding to the first acoustic signal. The data processing device 106 is further configured to receive the first position information sent by the depth sounder 102, and obtain a corresponding set of seabed depth and acoustic data according to the first position information and the second position information, and determine the submarine cable depth corresponding to the seabed depth. The data processing device 106 is configured to generate the burial depth of the submarine cable according to the seabed depth and the submarine cable depth, including: the data processing device 106 is configured to perform arithmetic processing on the seabed depth and the submarine cable depth corresponding to the seabed depth to generate the burial depth of the submarine cable.

[0070] Among them, the first position information may but is not limited to include at least one of the coordinates of the position where the depth sounder 102 is located when detecting the seabed depth and the detection time.

[0071] The second position information may but is not limited to include at least one of the coordinates of the position where the acoustic signal generator 104 is located when emitting the first acoustic signal and the emission time.

[0072] Specifically, the data processing device 106 receives the seabed depth sent by the depth sounder 102 and the first position information corresponding to the seabed depth, and establishes an association relationship between the seabed depth and the first position information. Receives the acoustic data carrying the second position information emitted by the acoustic signal generator 104. According to the first position information and the second position information, a set of seabed depth and acoustic data corresponding to the same position information is matched, an association relationship between the submarine cable depth and the position information corresponding to the set of acoustic data is established, and the submarine cable depth under the same position information as the seabed depth is determined. Arithmetic processing is performed on the seabed depth and the submarine cable depth corresponding to the seabed depth under the same position information to generate the burial depth of the submarine cable at this position information.

[0073] In this embodiment, the position information between the seabed depth and the acoustic wave data is used to determine the submarine cable depth corresponding to the seabed depth. According to the seabed depth and the submarine cable depth corresponding to the seabed depth under the same position information, the buried depth of the submarine cable at this position information is generated, which can improve the accuracy of the buried depth of the submarine cable generated by the submarine cable buried depth detection system.

[0074] In one embodiment, the data processing device 106 includes: a time synchronization device for controlling the same time of the depth sounder 102, the acoustic wave signal generator 104 and the data processing device 106.

[0075] Specifically, GPS devices are pre-set in the depth sounder 102, the acoustic wave signal generator 104 and the data processing device 106. The GPS device in the data processing device 106 communicates with the depth sounder 102 to obtain the initial time of the GPS device in the depth sounder 102, and sets the initial time of the GPS device in the depth sounder 102 to be the same as the initial time of the GPS device in the data processing device 106. The GPS device in the data processing device 106 communicates with the acoustic wave signal generator 104 to obtain the initial time of the GPS device in the acoustic wave signal generator 104, and sets the initial time of the GPS device in the acoustic wave signal generator 104 to be the same as the initial time of the GPS device in the data processing device 106.

[0076] In this embodiment, by controlling the same time of the depth sounder, the acoustic wave signal generator and the data processing device, the time accuracy of the seabed data sent by the depth sounder and the acoustic wave data sent by the acoustic wave signal generator received by the data processing device can be improved, thereby improving the accuracy of the generated buried depth of the submarine cable.

[0077] In one embodiment, the acoustic wave data includes the preset frequency and the emission time of the first acoustic wave signal. The data processing device 106 includes:

[0078] An optical fiber monitoring device is connected to the acoustic wave signal generator 104 and the sensing optical fiber 108, and is used to receive the preset frequency and the emission time sent by the acoustic wave signal generator 104, demodulate the acoustic wave signal received by the sensing optical fiber 108 according to the preset frequency, determine the first acoustic wave signal from the acoustic wave signal, and record the reception time of the first acoustic wave signal.

[0079] A control device is connected to the depth sounder 102 and the optical fiber monitoring device, and is used to receive the seabed depth sent by the depth sounder 102 and the preset frequency, the emission time and the reception time sent by the optical fiber monitoring device, determine the submarine cable depth according to the preset frequency, the emission time and the reception time, and generate the buried depth of the submarine cable according to the seabed depth and the submarine cable depth. In one example, the optical fiber monitoring device and the control device can be set in the same device, or the optical fiber monitoring device and the control device can be set in two independent devices.

[0080] Specifically, data communication is carried out between the optical fiber monitoring device and the acoustic wave signal generator 104 to receive the preset frequency and transmission time of the first acoustic wave signal sent by the acoustic wave signal generator 104. The optical fiber monitoring device is connected to the sensing optical fiber 108 to monitor the acoustic wave signal received by the sensing optical fiber 108. The acoustic wave signal received by the sensing optical fiber 108 is demodulated according to the preset frequency to determine the first acoustic wave signal from the acoustic wave signal, and the reception time corresponding to the first acoustic wave signal is obtained.

[0081] Data communication is carried out between the control device and the depth sounder 102 and the optical fiber monitoring device to receive the seabed depth sent by the depth sounder 102 and the preset frequency, transmission time and reception time sent by the optical fiber monitoring device. The second propagation rate of the first acoustic wave signal underwater is determined according to the preset frequency. The second time difference between the transmission time and the reception time corresponding to the first acoustic wave signal is obtained. Arithmetic processing is performed on the second propagation rate and the second time difference to determine the submarine cable depth. Arithmetic processing is performed on the seabed depth and the submarine cable depth to generate the buried depth of the submarine cable.

[0082] In this embodiment, the preset frequency and transmission time sent by the acoustic wave signal generator are received through the optical fiber monitoring device, and the acoustic wave signal received by the sensing optical fiber is monitored. Determining the first acoustic wave signal from the acoustic wave signal according to the preset frequency can improve the accuracy of obtaining the reception time of the first acoustic wave signal. By determining the submarine cable depth according to the preset frequency, transmission time and reception time through the control device, the accuracy of the determined submarine cable depth can be improved, thereby improving the accuracy of the generated buried depth of the submarine cable.

[0083] In one embodiment, the depth sounder 102 includes a transmitting transducer, a receiving transducer and a sounding device. The transmitting transducer is used to transmit a second acoustic wave signal. The receiving transducer is used to receive the second acoustic wave signal. The sounding device is used to record the time difference between the transmission of the second acoustic wave signal by the transmitting transducer and the reception of the second acoustic wave signal by the receiving transducer, and determine the seabed depth according to the time difference.

[0084] Specifically, the depth sounder 102 continuously transmits a second acoustic wave signal underwater through the transmitting transducer. The second acoustic wave signal propagates downward until it reaches the seabed. The second acoustic wave signal reflected by the seabed is received through the receiving transducer. The sounding device records the time difference between the transmission of the second acoustic wave signal by the transmitting transducer and the reception of the second acoustic wave signal by the receiving transducer. According to the frequency of the second acoustic wave signal, the propagation rate of the second acoustic wave signal is determined, and arithmetic processing is performed on the propagation rate and the time difference to determine the seabed depth. In one example, the second acoustic wave signal is a high-frequency acoustic wave. Since the acoustic intensity of the high-frequency acoustic wave gradually attenuates as the propagation distance increases, when the second acoustic wave signal reaches the seabed surface, it cannot penetrate the seabed and will be reflected by the seabed.

[0085] In this embodiment, by recording the time difference between the transmission of the second acoustic wave signal by the transmitting transducer and the reception of the second acoustic wave signal by the receiving transducer, and determining the seabed depth based on the time difference, the accuracy of the determined seabed depth can be improved.

[0086] In one embodiment, the depth sounder 102 includes any one of an echo sounder, a lift-compensated depth sounder, a towed depth sounder, a multi-beam depth sounder, and a dual-frequency depth sounder.

[0087] In this embodiment, by using any one of an echo sounder, a lift-compensated depth sounder, a towed depth sounder, a multi-beam depth sounder, and a dual-frequency depth sounder as the depth sounder to detect the seabed depth, the operation of seabed depth detection can be simplified, thereby improving the efficiency of seabed depth detection.

[0088] In one embodiment, as Figure 2 shown, a method for detecting the buried depth of a submarine cable is provided. In this embodiment, an example is given where this method is applied to a terminal. It can be understood that this method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. Among them, the terminal can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart TVs, smart vehicle-mounted devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server can be implemented by an independent server or a server cluster composed of multiple servers.

[0089] In this embodiment, the method includes the following steps:

[0091] Step S204, receiving the acoustic wave data sent by the acoustic wave signal generator.

[0092] Step S206, processing the acoustic wave signal received by the sensing optical fiber to determine the reception time of the first acoustic wave signal, and determining the submarine cable depth based on the acoustic wave data and the reception time.

[0093] Step S208, generating the buried depth of the submarine cable according to the seabed depth and the submarine cable depth.

[0094] Among them, the seabed depth can be used to represent the distance between the depth sounder and the seabed.

[0095] The acoustic wave data is obtained by recording the first acoustic wave signal with a preset frequency emitted by the acoustic wave signal generator. The acoustic wave data can include, but is not limited to, the preset frequency, the emission time, and the emission position of the first acoustic wave signal. The acoustic wave signal generator and the depth sounder can be arranged in the same waterborne device.

[0096] The sensing optical fiber is disposed in the submarine cable. In one example, the sensing optical fiber is a passive distributed optical fiber.

[0097] The depth of the submarine cable can be used to characterize the distance between the submarine cable and the acoustic signal generator.

[0098] The buried depth of the submarine cable can be used to characterize the distance between the submarine cable and the seabed.

[0099] Specifically, the terminal receives the seabed depth sent by the depth sounder and the acoustic data sent by the acoustic signal generator. The terminal monitors the acoustic signals received by the sensing optical fiber, processes the acoustic signals received by the sensing optical fiber, determines the first acoustic signal from the acoustic signals, and obtains the reception time of the first acoustic signal. The acoustic data and the reception time of the first acoustic signal are processed arithmetically to determine the depth of the submarine cable. The seabed depth and the depth of the submarine cable are processed arithmetically to generate the buried depth of the submarine cable.

[0100] In the above submarine cable buried depth detection method, by receiving the seabed depth transmitted by the depth sounder and the acoustic data of the first acoustic signal transmitted by the acoustic signal generator, processing the acoustic signals received by the sensing optical fiber, determining the reception time of the first acoustic signal, determining the depth of the submarine cable according to the acoustic data and the reception time, and generating the buried depth of the submarine cable according to the seabed depth and the depth of the submarine cable; it is possible to directly obtain the seabed depth and the depth of the submarine cable through the depth sounder and the acoustic signal generator in the same waterborne device without operating multiple devices underwater, and determine the buried depth of the submarine cable, thereby making the operation of the submarine cable buried depth detection system simple. In addition, since the submarine cable buried depth detection method provided in this application does not require operating multiple devices underwater, the cost of the submarine cable buried depth detection method is reduced.

[0101] In one embodiment, the acoustic data carries second position information corresponding to the first acoustic signal. The submarine cable buried depth detection method further includes: receiving the first position information corresponding to the seabed depth sent by the depth sounder; obtaining a corresponding set of seabed depth and acoustic data according to the first position information and the second position information, and determining the depth of the submarine cable corresponding to the seabed depth. Step S208, generating the buried depth of the submarine cable according to the seabed depth and the depth of the submarine cable, includes: processing the seabed depth and the depth of the submarine cable corresponding to the seabed depth arithmetically to generate the buried depth of the submarine cable.

[0102] Specifically, the terminal receives the first position information corresponding to the seabed depth sent by the fathometer, establishes an association relationship between the seabed depth and the first position information, compares multiple pieces of the first position information with the second position information, determines the seabed data and acoustic wave data where the first position information and the second position information are the same, and uses the seabed data and acoustic wave data with the same position information as a corresponding set of seabed depth and acoustic wave data. An association relationship is established between the cable depth corresponding to this set of acoustic wave data and the position information, and the cable depth at the same position information as the seabed depth is determined. Arithmetic processing is performed on the seabed depth and the cable depth corresponding to the seabed depth at the same position information to generate the buried depth of the cable at this position information.

[0103] In this embodiment, through the position information between the seabed depth and the acoustic wave data, the cable depth corresponding to the same position information as the seabed depth is determined, and based on the seabed depth and the cable depth at the same position information, the buried depth of the cable at this position information is generated, which can improve the accuracy of the buried depth of the cable generated by the cable buried depth detection system.

[0104] In one embodiment, the step of performing arithmetic processing on the seabed depth and the cable depth corresponding to the seabed depth to generate the buried depth of the cable includes: comparing the cable depths at multiple position information to determine the target cable depth; performing arithmetic processing on the target cable depth and the seabed depth corresponding to the target cable depth to generate the buried depth of the cable.

[0105] Among them, the target cable depth can be used to represent the distance between the acoustic signal generator and the cable when the acoustic signal generator is directly above the cable.

[0106] Specifically, the terminal obtains the cable depths at multiple position information, compares the cable depths at multiple position information, and uses the cable depth that meets the preset target condition as the target cable depth. Obtain the seabed depth corresponding to the target cable depth, perform arithmetic processing on the target cable depth and the seabed depth corresponding to the target cable depth, and use the difference between the target cable depth and the seabed depth as the buried depth of the cable. Among them, the preset target condition can be the shortest cable depth obtained within a preset time, or the shortest cable depth obtained within a preset range.

[0107] In this embodiment, by determining the target cable depth when the acoustic signal generator is directly above the cable, and based on the target cable depth and the seabed depth corresponding to the target cable depth, the buried depth of the cable is generated, which can improve the accuracy of the generated buried depth of the cable.

[0108] In one embodiment, the acoustic wave signal includes a preset frequency and a transmission time of the first acoustic wave signal. Step S204: Receive the acoustic wave data sent by the acoustic wave signal generator; Step S206: Process the acoustic wave signal received by the sensing optical fiber to determine the reception time of the first acoustic wave signal, and determine the submarine cable depth according to the acoustic wave data and the reception time, including: receiving the preset frequency and the transmission time sent by the acoustic wave signal generator, demodulating the acoustic wave signal received by the sensing optical fiber according to the preset frequency, determining the first acoustic wave signal from the acoustic wave signal, recording the reception time of the first acoustic wave signal, and determining the submarine cable depth according to the preset frequency, the transmission time, and the reception time.

[0109] Specifically, the terminal receives the preset frequency and the transmission time sent by the acoustic wave signal generator, demodulates the acoustic wave signal received by the sensing optical fiber according to the preset frequency, determines the first acoustic wave signal from the acoustic wave signal, records the reception time of the first acoustic wave signal, and determines the second propagation rate of the first acoustic wave signal underwater according to the preset frequency. Obtain the second time difference between the transmission time and the reception time corresponding to the first acoustic wave signal. Perform arithmetic processing on the second propagation rate and the second time difference to determine the submarine cable depth.

[0110] In this embodiment, by demodulating the acoustic wave signal received by the sensing optical fiber according to the preset frequency of the first acoustic wave signal, determining the first acoustic wave signal from the acoustic wave signal, obtaining the reception time of the first acoustic wave signal, and determining the submarine cable depth according to the preset frequency, the transmission time, and the reception time, it is possible to avoid the influence of interference acoustic waves generated by the external environment on the sensing optical fiber, reduce errors, improve the accuracy of the obtained submarine cable depth, and thus improve the accuracy of the generated submarine cable burial depth.

[0111] In one embodiment, as Figure 3a shown, a method for detecting the burial depth of a submarine cable is provided, including:

[0112] Step S302: Receive the seabed depth sent by the depth sounder, and the first position information corresponding to the seabed depth.

[0113] Step S304: Receive the preset frequency and the transmission time carrying the second position information sent by the acoustic wave signal generator.

[0114] Specifically, the terminal receives the seabed depth sent by the depth sounder, and the first position information corresponding to the seabed depth, and receives the preset frequency and the transmission time carrying the second position information sent by the acoustic wave signal generator. Establish an association relationship between the seabed depth and the first position information. Monitor the acoustic wave signal received by the sensing optical fiber, demodulate the acoustic wave signal received by the sensing optical fiber according to the preset frequency, determine the first acoustic wave signal from the acoustic wave signal, and record the reception time of the first acoustic wave signal.

[0115] Step S306: Demodulate the acoustic wave signals received by the sensing optical fiber at a preset frequency, determine the first acoustic wave signal from the acoustic wave signals, record the reception time of the first acoustic wave signal, and determine the submarine cable depth based on the preset frequency, transmission time, and reception time.

[0116] S308: Obtain a corresponding set of seabed depths and acoustic wave data based on the first position information and the second position information, and determine the submarine cable depth corresponding to the seabed depth.

[0117] S310: Compare the submarine cable depths under multiple position information, determine the target submarine cable depth, and perform arithmetic processing on the target submarine cable depth and the seabed depth corresponding to the target submarine cable depth to generate the buried depth of the submarine cable.

[0118] Specifically, the terminal determines the second propagation rate of the first acoustic wave signal underwater according to the preset frequency. Obtain the second time difference between the transmission time and the reception time corresponding to the first acoustic wave signal. Perform arithmetic processing on the second propagation rate and the second time difference to determine the submarine cable depth. Compare multiple first position information and second position information, determine the seabed data and acoustic wave data where the first position information and the second position information are the same, and use the seabed data and acoustic wave data with the same position information as a corresponding set of seabed depths and acoustic wave data. Establish an association relationship between the submarine cable depth corresponding to this set of acoustic wave data and the position information, and determine the submarine cable depth at the same position information as the seabed depth. Compare the submarine cable depths under multiple position information, determine the target submarine cable depth, and perform arithmetic processing on the target submarine cable depth and the seabed depth corresponding to the target submarine cable depth to generate the buried depth of the submarine cable.

[0119] In one example, as Figure 3b shown, an echo sounder can be used as the depth sounder, and the echo sounder and the acoustic wave signal generator are arranged inside a ship on the sea surface. Move the position of the ship, emit a second acoustic wave signal through the echo sounder, and obtain in real time the seabed depth between the current position and the seabed. Real-time emit the first acoustic wave signal with a preset frequency through the acoustic wave signal generator, and record the transmission time of the first acoustic wave signal. Process the acoustic wave signals received by the sensing optical fiber to determine the reception time of the first acoustic wave signal. Determine the submarine cable depth based on the preset frequency, transmission time, and reception time. Generate the buried depth of the submarine cable based on the submarine cable depth and the seabed depth

[0120] The buried depth of the submarine cable can be obtained through the following formula:

[0121]

[0122] h2 = v2(t3 - t2)

[0123] H = h2 - h1

[0124] Among them, h1 is the seabed depth, v1 is the propagation speed of the second acoustic wave signal underwater, and Δt1 is the time difference between the emission time and the reception time of the second acoustic wave signal. h2 is the submarine cable depth, v2 is the propagation speed of the first acoustic wave signal underwater, t3 is the reception time of the first acoustic wave signal, t2 is the emission time of the first acoustic wave signal, and H is the burial depth of the submarine cable.

[0125] In an example, when the echo sounder is higher than the acoustic wave signal generator, the burial depth of the submarine cable can be obtained through the following formula:

[0126] H = h2 - h1 + L

[0127] When the echo sounder is lower than the acoustic wave signal generator, the burial depth of the submarine cable can be obtained through the following formula:

[0128] H = h2 - h1 - L

[0129] Among them, L is the height difference between the echo sounder and the acoustic wave signal generator.

[0130] In an example, when the specific position of the submarine cable is uncertain, the acoustic wave signal generator can be used to emit the first acoustic wave signal with a preset frequency. The terminal receives the preset frequency and the emission time of the first acoustic wave signal, determines the reception time of the first acoustic wave signal, determines the distance between the acoustic wave signal generator and the submarine cable at this time according to the preset frequency, emission time and reception time, and obtains the positional relationship between the acoustic wave signal generator and the submarine cable, that is, the position where the sensing optical fiber in the submarine cable receives the first acoustic wave signal is on the spherical surface with the acoustic wave signal generator as the center of the circle and the distance between the acoustic wave signal generator and the submarine cable as the radius. Move the ship carrying the depth sounder and the acoustic wave signal generator, and repeat to obtain the distances between the acoustic wave signal generator and the submarine cable at multiple positions, so as to obtain the GPS position of the submarine cable and the path information of the submarine cable. When the distance between the acoustic wave signal generator and the submarine cable is the shortest, it is determined that the acoustic wave signal generator is directly above the submarine cable, and the burial depth of the submarine cable is generated by performing arithmetic processing on the seabed depth and the submarine cable depth obtained by the depth sounder at this position.

[0131] In this embodiment, detection is performed through a depth sounder and an acoustic signal generator provided on the same waterborne device, and data collection is automatically completed. It is possible to avoid operating multiple underwater devices, making the operation of the submarine cable burial depth detection method simple, improving the efficiency of the submarine cable burial depth detection method, and reducing the cost of the submarine cable burial depth detection method. By emitting a first acoustic signal with a preset frequency through the acoustic signal generator and demodulating the acoustic signal received by the sensing optical fiber at the preset frequency to determine the reception time of the first acoustic signal, interference from external noise to the acoustic signal received by the sensing optical fiber can be avoided, reducing the time error, thereby improving the accuracy of the submarine cable depth. By using a sensing optical fiber with passive access, the safety of the submarine cable burial depth detection method can be improved. In addition, since both the depth sounder and the acoustic signal generator are physical devices on the water, they are not affected by changes in the external environment, thus improving the versatility of the submarine cable burial depth detection method.
