Description

Technical Field

[0001] The present application relates to the technical field of acoustic signal transmission, and in particular to an underwater acoustic signal transmission system. Background Art

[0002] With the intensification and expansion of human economic and military activities, the demand for national defense security, energy security, underwater engineering safety, and submarine acoustic data research is increasing. This has led to increasing frequency of human marine activities and a continuous increase in the construction and investment of marine engineering. This growth in marine engineering construction and investment has also increased the demand for monitoring acoustic data around underwater engineering and marine biological resources.

[0003] The frequencies of the detection waves used for oceanographic surveys are mostly within the human hearing range, so oceanographic surveying technology is often referred to as acoustic wave surveying. Compared to light and electromagnetic waves, acoustic waves are the only waves that travel the longest underwater and are the most useful. They are widely used for oceanographic research, development, and military purposes. Underwater acoustic technology is used in various naval underwater communications and is a primary application for underwater detection and monitoring. Acoustic waves are also a crucial tool for oceanographic research, resource development, and navigation.

[0004] like Figure 2 As shown, current ocean information transmission primarily occurs via cables connecting ocean current meters (AWCP equipment) to base stations. However, cable laying requires various conditions. Underwater cables should be continuous and laid in locations with stable riverbeds and minimal impact on riverbanks. Reliable protective measures must be implemented when laying cables near docks, anchorages, harbors, ferry crossings, and areas where ships are moored. Underwater cables must be laid flat on the seabed and not left hanging. During underwater operation, cables can be snagged by passing vessels, causing line severance and disrupting work progress. Relaying cables is also time-consuming and labor-intensive, making it impossible to secure and monitor acoustic information in relevant areas (such as oil fields and military areas) in real time. Over time, cables have a limited lifespan. With increased use, cable attenuation increases, leading to a higher failure rate for amplifiers at relay stations. Seawater is rich in compounds, which can lead to increased oxidation at the connectors.

[0006] In response to the shortcomings of the existing technology, the present application discloses an underwater acoustic signal transmission system to solve the problems of low working efficiency of existing traditional signal transmission cables, cable transmission being easily damaged by objective factors, and difficulty in recovering after interruption of acoustic wave transmission.

[0007] This application is implemented through the following technical solutions:

[0008] The application provides an underwater acoustic signal transmission system, comprising an ocean current meter (AWCP device) and a base station, wherein the AWCP device is connected with the base station through an acoustic transmission system, the acoustic transmission system is provided with one or more transceiving modules matched in quantity and path, and is used for realizing information interaction between the base station and the information detected by the ocean current meter through acoustic signals.

[0009] In an embodiment of the application, the acoustic transmission system comprises a preprocessing system and a comprehensive system, the preprocessing system is used for sending the detected information provided by the ocean current meter to the comprehensive system after data recording, storage and judgment, the comprehensive system is used for sending the acoustic signals to the base station after comprehensive processing, the preprocessing system assists the ocean current meter in collecting the detected information in an acoustic detection mode through an acoustic sensor, and the detected information is transmitted to a signal collection unit for data recording, storage and judgment, and then is sent to the comprehensive system, when the signal collection unit does not collect the detected information, it represents that the current detected information is not collected, at this time, a callback signal is fed back to the ocean current meter to collect the detected information again.

[0010] In an embodiment of the application, when the signal collection unit collects the detected information again and still does not capture the detected information, the signal collection unit feeds back the current result to a backup conversion system, the backup conversion system analyzes the type of the uncollected detected information through an analysis unit, and obtains backup acoustic signal collection data through an addition unit, the addition unit is used for integrating other detected information into the required detected information through an algorithm program and transmitting the required detected information to the comprehensive system for processing.

[0011] In an embodiment of the application, the comprehensive system comprehensively processes the current detected information through a comparison unit and a filtering unit, classifies the current detected information through an identification processing unit, determines a sending period, and then sends the current detected information to a signal transmitting unit, the signal transmitting unit converts the detected information into acoustic signals and sends the acoustic signals to a corresponding matched receiving unit, the receiving unit stores the transmitted acoustic signals again and sends the acoustic signals to the base station, the comparison unit is connected with the filtering unit, the comparison unit is used for comparing and distinguishing the acoustic signals, and the filtering unit filters out unidentified clutter contained in the acoustic signals.

[0012] In an embodiment of the application, when the acoustic signals are transmitted in an integral mode, the acoustic signals are directly sent to the acoustic transmission system through an integration unit.

[0013] In an embodiment of the application, when the acoustic signals are transmitted in a single mode, the integration unit sends the detected information to a frequency selection unit, classifies the detected information into different signal modules, and then sends the detected information to the acoustic transmission system.

[0014] In one embodiment of the present application, the integration unit is used to meet the requirements of classification and integration of different sound wave frequencies.

[0015] In one embodiment of the present application, the signal modules do not interfere with each other and work independently.

[0016] In one embodiment of the present application, the sound wave transmission system uses lateral sound wave transmission to transmit sound waves; wherein the information contained in the sound wave signal includes: one or more of the temperature, density, flow velocity, flow direction, wave height and wave direction of the ocean current.

[0017] In one embodiment of the present application, the sound wave transmission system includes a sound wave transmitting module and a sound wave receiving module, and the sound wave transmitting module and the sound wave receiving module are interactively connected through sound wave signals; wherein, the sound wave transmission system is provided with one or more equal-number path-matched transceiver modules to select single differentiated transmission or overall transmission.

[0018] The beneficial effects of this application are:

[0019] 1. In the past, underwater information transmission mostly used a single cable transmission. However, this application improves the cable data transmission method. It improves the problem that traditional cables are easily corroded by seawater after long use, require regular quality inspections and are difficult to repair, and are easily broken by passing ships. The disadvantage of limited wireless transmission on the seabed is solved by using sound waves for lateral transmission and intelligent analysis through the sound wave transmission system, solving the problem of transmitting information from seabed resources.

[0020] 2. This application collects acoustic signals from acoustic sensors and classifies and organizes them through a signal acquisition unit. A comprehensive system identifies the currently collected acoustic signals and sends them to the corresponding acoustic signal receiving station, improving detection and matching efficiency. This provides a rational distribution and propagation of acoustic signals for seabed resource exploration, saving human resources while improving propagation efficiency and resolving the issue of the AWCP system's inability to achieve optimal acoustic propagation matching.

[0021] 3. The backup conversion system improves the effectiveness and integrity of the transmitted sound wave signal. If a problem occurs with the transmission of the currently required sound wave signal, resulting in the inability to transmit or capture the current sound wave signal, the addition unit integrates the remaining sound wave signals until the missing sound wave signal is matched. The integrated sound wave signal reaches the same transmission frequency as the missing sound wave signal, greatly improving the convenience and matching integrity when the sound wave signal fails, ensuring the maximum signal transmission each time. This ensures the security of data collection, sound wave transmission, and storage for both the sender and receiver.

[0022] 4. This application uses a mode switching system to integrate and classify transmitted acoustic signals, reducing the number of troubleshooting operations and allowing different types of acoustic signals to be processed separately without interfering with each other. This enables orderly management of acoustic signal transmission, fully meeting the requirements for underwater acoustic signal transmission.

[0023] 5. The underwater acoustic signal transmission system of the present application has excellent acoustic signal transmission effect and strong practicality. It solves the shortcomings of the existing traditional signal transmission cables, such as low working efficiency, cable transmission easily damaged by objective factors, and difficulty in recovering interrupted acoustic transmission, and is suitable for promotion and use.

DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] See also Figure 1 This is a schematic diagram of the internal framework system of the present application. The present application provides an underwater acoustic signal transmission system, for example, including an AWCP device 1, an acoustic wave transmission system 4, and a base station 2. The AWCP device 1 is an ultrasonic wave direction, wave height, and profile oceanographic instrument (Acoustic Wave Current Profiler). The AWCP device 1 determines the transmission mode via a mode switching system 3 and then transmits the signal to the acoustic wave transmission system 4. The mode switching system 3 determines whether the currently transmitted acoustic signal is a single, differentiated transmission or an overall transmission via an integration unit 6. The integration unit 6 satisfies the classification and integration of different acoustic wave frequencies.

[0034] In one embodiment, the acoustic wave signal transmission method is transverse acoustic wave transmission, which is different from the longitudinal acoustic wave transmission method used for detection.

[0035] In one embodiment, if Figure 3 As shown, the ocean current meter (AWCP device) 1 is connected to the base station 2 through the acoustic wave transmission system 4. The acoustic wave transmission system 4 is provided with one or more transceiver modules with equal number and path matching, which are used to realize information exchange between the information detected by the ocean current meter (AWCP device) 1 and the base station 2 using acoustic wave signals.

[0036] In one embodiment, the acoustic wave transmission system 4 is provided with one or more transceiver modules with equal number and path matching, for using acoustic wave signals to realize information exchange between the information detected by the ocean current meter (AWCP device) 1 and the base station 2 .

[0037] In one embodiment, the acoustic wave transmission system 4 is provided with one or more transceiver modules with equal number and path matching to select single differentiated transmission or overall transmission.

[0038] In one embodiment, if Figure 4 As shown, the sound wave transmission system 4 includes, for example, a sound wave transmitting module 19 and a sound wave receiving module 20 , and the sound wave transmitting module 19 and the sound wave receiving module 20 are interactively connected via sound wave signals.

[0039] In one embodiment, the acoustic wave transmitting module 19 is assembled into five transmitting modules in a single manner. If a single module is damaged during use, the damaged module can be replaced by another single module in the form of interactive coding for transmission.

[0040] In one embodiment, the sound wave receiving module 20 is assembled with five receiving modules in a single manner. If a single module is damaged during use, the damaged module can be replaced by another single module in the form of interactive coding for reception.

[0041] In one embodiment, if a single module in both the acoustic wave transmitting module 19 and the acoustic wave receiving module 20 is damaged, information can be transmitted or received alternately using another single module in an interactively coded manner in place of the damaged module. For example, assume that the acoustic wave transmitting module 19 has five transmitting modules, numbered 1, 2, 3, 4, and 5 from top to bottom, and the acoustic wave receiving module 20 has five receiving modules, numbered A, B, C, D, and E from top to bottom. The acoustic wave transmitting module 19 and the acoustic wave receiving module 20 are both connected from top to bottom.

[0042] In some embodiments, when the transmitting module (number 1) is damaged and the receiving module (number A) cannot receive a signal, the transmitting modules (numbers 2 and 3) simultaneously transmit a long-wave signal for several seconds (e.g., 2 seconds, 3 seconds, 4 seconds, 5 seconds, etc., or more), and the transmitting module (number 2) transmits the frequency signal that should be transmitted by the transmitting module (number 1), and the receiving module (number A) receives the signal. Similarly, when the transmitting module (number 2) is damaged and the receiving module (number B) cannot receive a signal, the transmitting modules (numbers 3 and 4) simultaneously transmit a long-wave signal for several seconds (e.g., 2 seconds, 3 seconds, 4 seconds, 5 seconds, etc., or more), and the transmitting module (number 3) transmits the frequency signal that should be transmitted by the transmitting module (number 2), and the receiving module (number B) receives the signal. And so on.

[0043] Conversely, when the receiving module (number A) is damaged, the receiving modules (numbers B, C) or other auxiliary signal transmitters will send a continuous long-wave signal in the reverse direction for several seconds (e.g., 2 seconds, 3 seconds, 4 seconds, 5 seconds, etc., or more). After receiving the signal, the acoustic wave transmitting module 19 will transmit the frequency signal of module (number 1), and the receiving module (number B) will receive the signal. Similarly, when the receiving module (number B) is damaged, the receiving modules (numbers C, D) or other auxiliary signal transmitters will send a continuous long-wave signal in the reverse direction for several seconds (e.g., 2 seconds, 3 seconds, 4 seconds, 5 seconds, etc., or more). After receiving the signal, the acoustic wave transmitting module 19 will transmit the frequency signal of module (number 2), and the receiving module (number C) will receive the signal. And so on.

[0044] In some embodiments, when the sending modules and receiving modules of different paths are damaged at the same time, for example, the sending module (number 1) and the receiving module (number B) are damaged at the same time, the acoustic wave transmitting module 19 and the acoustic wave receiving module 20 are instructed by the path joint adjustment through other paths first. After the path adjustment, the sending module (number 2) and the receiving module (number A) form an available acoustic wave sending path.

[0045] In one embodiment, the acoustic wave signal includes, for example, one or more of temperature, density, flow velocity, flow direction, wave height, and wave direction.

[0046] In one embodiment, if Figure 5 As shown, the acoustic wave transmission system 4 selects integrated transmission. When the acoustic wave signal is transmitted as a whole, the integration unit 6 integrates the acoustic wave signal and sends it directly to the acoustic wave transmission system 4. When the acoustic wave signal is transmitted separately, the integration unit 6 transmits the acoustic wave signal to the frequency selection unit 7, which classifies the acoustic wave signal into different signal modules and then sends them to the acoustic wave transmission system 4. The signal modules do not interfere with each other and operate independently.

[0047] In one embodiment, the sound wave transmission system 4 transmits sound waves using a transverse sound wave transmission method.

[0048] In one embodiment, a mode switching system 3 is used to integrate and classify propagating acoustic signals. This not only reduces the number of troubleshooting operations but also allows for different types of acoustic signals to be processed separately without interfering with each other. This enables orderly management of acoustic signal transmission, fully meeting the requirements for underwater acoustic signal propagation.

[0049] In one embodiment, the acoustic wave transmission system 4 includes, for example, a preprocessing system 8 and an integrated system 11. The preprocessing system 8 assists the ocean current meter (AWCP device) 1 in collecting detection information through an acoustic wave sensor 9 by acoustic wave detection, and transmits the detection information to the signal acquisition unit 10 for data recording, storage, and judgment, and then sends it to the integrated system 11.

[0050] In one embodiment, detection information from acoustic wave sensors 9 is collected and classified and organized by a signal acquisition unit 10. This information is then identified by an integrated system 11 and converted into acoustic wave signals for transmission to the corresponding acoustic wave signal receiving stations, improving detection and matching efficiency. This approach provides a rational distribution of acoustic wave signals for seabed resource exploration, saving human resources while improving transmission efficiency and resolving the issue of the AWCP system's inability to achieve optimal acoustic wave propagation matching.

[0051] In one embodiment, when the signal collection unit 10 fails to collect detection information, it means that the current detection information has not been collected. At this time, a callback signal is fed back to the AWCP system for re-collection.

[0052] In one embodiment, when the signal acquisition unit 10 fails to capture detection information after another acquisition, the signal acquisition unit 10 feeds back the current result to the backup conversion system 5. The backup conversion system 5 analyzes the type of the uncollected detection information through the analysis unit 16 and obtains the backup detection information acquisition data through the addition unit 17.

[0053] In one embodiment, the adding unit 17 is used to integrate other detection information into the required detection information through an algorithm program and transmit it to the integrated system 11 for processing.

[0054] In one embodiment, the integrated detection information does not interfere with the detection information collected by the signal acquisition unit 10. After the transmission of the currently collected detection information is completed, it can still obtain the missing detection information by integrating other detection information and perform normal detection information transmission.

[0055] In one embodiment, the backup conversion system 5 improves the validity and integrity of the transmitted detection information. If a problem occurs with the transmission of the currently required detection information, resulting in the inability to transmit or capture the current detection information, the addition unit 17 integrates the remaining detection information until the missing detection information is matched. The integrated detection information achieves the same transmission frequency as the missing detection information, greatly improving the convenience and matching integrity when a transmission path failure occurs, ensuring maximum signal transmission for each transmission. This ensures the security of data collection, acoustic wave transmission, and storage for both the sender and receiver.

[0056] In one embodiment, the integrated system 11 performs integrated processing on the current detection information through the comparison unit 12 and the filtering unit 18. The comparison unit 12 is connected to the filtering unit 18. The comparison unit 12 is used to compare and distinguish the detection information. The filtering unit 18 filters out unrecognizable clutter contained in the detection information.

[0057] In one embodiment, the recognition processing unit 13 classifies the current detection information and determines the transmission time period before sending it to the signal transmitting unit 14. The signal transmitting unit 14 converts the detection information into an acoustic signal and sends it to the corresponding matching receiving unit 15. After receiving the transmitted acoustic signal, the receiving unit 15 stores it again and sends it to the base station 2.

[0058] In the past, underwater information transmission mostly used a single cable transmission. However, this application improves the cable data transmission method. It improves the problem that traditional cables are easily corroded by seawater after long use, require regular quality inspections and are difficult to repair, and are easily cut by passing ships. The disadvantage of limited wireless transmission on the seabed is solved by using sound waves for lateral transmission and intelligent analysis through the sound wave transmission system 4, solving the problem of transmitting information on seabed resources.

[0059] In one embodiment, acoustic wave signals from acoustic wave sensors are collected, classified, and organized by a signal acquisition unit 10. An integrated system 11 identifies the currently collected acoustic wave signals and transmits them to the corresponding acoustic wave signal receiving station, improving detection and matching efficiency. This provides a rational distribution of propagated acoustic wave signals for seabed resource exploration, saving human resources while improving propagation efficiency and resolving the issue of the AWCP system's inability to achieve optimal acoustic wave propagation matching.

[0060] In one embodiment, the backup conversion system 5 improves the effectiveness and integrity of the transmitted acoustic signal. If a problem occurs with the transmission of the currently required acoustic signal, resulting in the inability to transmit or capture the current acoustic signal, the addition unit 17 integrates the remaining acoustic signals until the missing acoustic signal is matched. The integrated acoustic signal achieves the same transmission frequency as the missing acoustic signal, greatly improving the convenience and matching integrity when acoustic signal failures occur, ensuring maximum signal transmission each time. This ensures the security of data collection, acoustic transmission, and storage for both the sender and receiver.

[0061] In one embodiment, a mode switching system 3 is used to integrate and classify propagating acoustic signals. This not only reduces the number of troubleshooting operations but also allows for different types of acoustic signals to be processed separately without interfering with each other. This enables orderly management of acoustic signal transmission, fully meeting the requirements for underwater acoustic signal propagation.

[0062] In summary, the underwater acoustic signal transmission system of the present application has excellent acoustic signal transmission effect and strong practicality. It solves the shortcomings of existing traditional signal transmission cables, such as low working efficiency, cable transmission being easily damaged by objective factors, and difficulty in recovering interrupted acoustic transmission, and is suitable for promotion and use.
