Description

Technical Field

[0001] The present disclosure belongs to the field of communication technologies, and particularly relates to an information control platform, a marine communication system, and a communication method. Background Art

[0002] The development of marine communication systems is crucial for maritime activities such as ocean exploration, maritime rescue, and ocean resource development. Modern marine communication systems are not only required to have the ability to transmit real-time data with high bandwidth and low latency, but also need to adapt to complex and changing marine environments, such as extreme weather and deep-sea high pressure. Currently, marine communication networks mainly use discrete communication networks such as shore-based mobile communication, maritime wireless communication, satellite communication, and underwater acoustic communication to achieve basic coverage of the global ocean. Among them, shore-based mobile communication mainly relies on mobile communication networks such as 2G / 3G / 4G / 5G to achieve effective coverage of near-shore signals; maritime wireless communication mainly uses medium / high frequency and very high frequency communication to achieve coverage of near-shore and mid-far sea areas. Both shore-based mobile communication systems and maritime wireless communication systems can be shore-based communication systems.

[0003] Briefly speaking, the core idea of shore-based communication systems is to utilize the characteristics of high flexibility and easy self-networking of ship-based marine communication systems, and use large ships as relay nodes to increase signal strength and coverage.

[0034] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0035] Unless otherwise defined, the technical terms or scientific terms used in this disclosure shall have the ordinary meaning as understood by those of ordinary skill in the art to which this disclosure belongs. The "first", "second" and similar terms used in this disclosure do not denote any order, quantity or importance, but are only used to distinguish different components. Similarly, terms such as "a", "an" or "the" do not denote a quantity limitation, but mean that there is at least one. The terms such as "comprising" or "including" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0036] As used herein, "parallel" and "perpendicular" include the described situations and situations similar to the described situations, and the range of the similar situations is within an acceptable deviation range, where the acceptable deviation range is determined by those of ordinary skill in the art considering the measurements being discussed and the errors associated with the measurements of specific quantities (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5° deviation; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5° deviation.

[0037] It should be understood that when a layer or element is referred to as being on another layer or substrate, it may be that the layer or element is directly on the other layer or substrate, or there may be an intermediate layer between the layer or element and the other layer or substrate.

[0038] In this text, "electrically connected" includes cases where components are connected together through elements having certain electrical functions. There are no particular limitations on the "elements having certain electrical functions" as long as they can transfer electrical signals between the components to be connected. Examples of the "elements having certain electrical functions" include not only electrodes and wirings, but also switching elements such as transistors, resistors, inductors, capacitors, and other elements having various functions.

[0039] Exemplary embodiments are described herein with reference to cross-sectional views and / or plan views as idealized exemplary drawings. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Therefore, variations in the shape with respect to the drawings due to, for example, manufacturing techniques and / or tolerances can be envisioned. Thus, the exemplary embodiments should not be construed as being limited to the shapes of the regions shown herein, but rather include shape deviations caused by, for example, manufacturing. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the regions of the device and are not intended to limit the scope of the exemplary embodiments.

[0040] In the related art, in order to enhance the stability of signal transmission and reception between a shipborne communication system and a base station, means such as improving antenna gain and optimizing signal processing algorithms are often adopted.

[0041] For example, in a marine communication system disclosed in a patent, the direction of the antenna is adjusted by means of electric control or mechanical rotation to track the base station signal, thereby ensuring the quality of the base station signal received by it. This communication system performs well in static scenarios, but in a rapidly changing marine environment, the mechanical rotation has a high delay and poor accuracy, making it difficult to achieve real-time response in the case of high-speed movement and quickly establish a connection with the base station.

[0042] Again, for example, a patent provides an optimization technique for an antenna architecture, which increases the number of antenna elements in an antenna array to improve signal stability. However, this method will cause a sharp increase in the overall volume of the antenna, so it is difficult to be applied to ships with limited space, and the application scenario is very limited.

[0043] In addition, the shipborne communication systems in the related art also have the following problems: 1. The shipborne communication system highly depends on a single signal source, lacks effective fault tolerance mechanisms and backup link management. Once the signal of a certain base station is blocked or the signal quality deteriorates, communication interruption is likely to occur, affecting the stability and continuity of the system. 2. In a complex and changeable marine environment, the shipborne communication system is difficult to maintain continuous high-quality communication, so its reliability is low.

[0044] In order to expand the signal coverage range, in the related art, a repeater is often used to achieve coverage enhancement. Figure 1 It is a process diagram of the working principle of using a repeater to achieve coverage enhancement, asFigure 1 As shown, this solution uses large ships as relay nodes to transmit the base station signals received by near - sea ships to the communication system of far - sea ships through the relay nodes, so as to expand the communication coverage and provide connection and communication services for more marine terminals.

[0045] Figure 2 It is a schematic diagram of the module structure of the communication system in the repeater. Refer to Figure 2 , the working process of this repeater is roughly as follows: The weak electromagnetic wave signals received by the receiving antenna ANT1 are processed by the low - noise amplifier LNA, band - pass filter BPF, mixer Mixer, etc., and then converted into digital signals by the analog - to - digital signal converter DAC. After being processed by the digital signal processor DSP, they are converted back into analog signals by the digital - to - analog signal converter ADC, and then subjected to operations such as mixing, filtering, and power amplification again before being transmitted to the transmitting antenna ANT2. The transmitting antenna ANT2 transmits the processed and amplified analog signals, so as to achieve the purpose of enhancing the signal and expanding the signal coverage.

[0046] However, the inventor found that in the above - mentioned solution, the on - ship communication systems on each ship work independently, repeatedly consuming computing resources and communication resources. There is a lack of a collaborative working mechanism between the communication systems, resulting in the inability to effectively utilize collaborative resources; moreover, the repeater cannot quickly identify signal anomalies and cannot quickly detect and repair when the connection between the near - sea ship and the signal source is abnormal, thus unable to ensure the communication continuity of the far - sea ship; in addition, the repeater cannot determine the best signal source from multiple signal sources and it is difficult to ensure the best signal quality received by the far - sea ship.

[0047] To solve at least one of the technical problems in the related art, on the one hand, the present disclosure provides an information control platform. This information control platform is applied to the marine communication system, Figure 3 It is a schematic diagram of the structure of the marine communication system. As Figure 3 shown, the marine communication system includes a main communication device 1 and a plurality of communication devices 2, where the main communication device 1 includes the above - mentioned information control platform.

[0048] Figure 4 It is an exemplary modular structure diagram of the information control platform. As Figure 4 shown, the information control platform includes: a judgment module 11, an analysis module 12, and a first transmission module 13.

[0049] Among them, the judgment module 11 is configured to, in response to the feedback signals of each communication device 2, judge whether each feedback signal includes a shore - based signal, and mark the communication device 2 whose feedback signal includes a shore - based signal as the first communication device 21, and mark other communication devices as the second communication device 22; Continuing Figure 3 the marine communication system shown inFigure 5 It is a schematic diagram of multiple communication devices in the communication system, including a first communication device and a second communication device. It can be understood that, relative to the second communication device 22, the first communication device 21 is closer to the shore base station, and it is easier to establish a communication connection with the shore base station. However, since the second communication device 22 is farther away from the shore base station, its signal radiation range is limited and it cannot directly establish a communication connection with the shore base station. Since the second communication device 22 cannot establish a communication connection with the shore base station, while the first communication device 21 can receive the shore-based signal, the signals fed back by the first communication device 21 and the second communication device 22 to the information control platform are different. The judgment module 11 can judge what type of communication device each communication device belongs to based on the difference in the signals fed back by the two.

[0050] The analysis module 12 is configured to analyze the signal parameters of the shore-based signals received by each first communication device 21, and determine one of the first communication devices 21 as the target communication device based on the signal parameters of the shore-based signals received by each first communication device 21. Among them, the signal parameters include one or more of signal strength, signal-to-noise ratio, signal phase, signal delay time, bit error rate, frame error rate, etc. Specifically, the analysis module 12 analyzes the signal parameters of the shore-based signals received by each first communication device 21, and scores the signal quality of the shore-based signals received by each first communication device 21 based on a preset evaluation method, and takes the first communication device 21 with the highest score as the target communication device, so that each second communication device 22 preferentially tracks the shore-based signal received by the target communication device.

[0051] The first transmission module 13 is configured to transmit the shore-based signal received by the target communication device to each second communication device 22.

[0052] The information control platform provided by the present disclosure determines the first communication device that can be connected to the shore base station from each communication device through the judgment module, uses the analysis module to analyze the signal parameters of the shore-based signals received by each first communication device, determines the target communication device, and then through the first transmission module, forwards the shore-based signal received by the target communication device to the second communication device, so that the second communication device can establish a communication connection with the shore base station. This information control platform can ensure that in a dynamic and complex environment, the second communication device can receive high-quality and high-stability shore-based signals, thereby improving the signal tracking efficiency of the second communication device, and then improving the coverage and reliability of the maritime communication system.

[0053] Figure 6 It is another exemplary modular structure schematic diagram of the information control platform. As Figure 6As shown, in some alternative embodiments, in addition to the determination module 11, the analysis module 12, and the first transmission module 13, the information control platform further includes a second transmission module 14 and a reception module 15. Among them, the second transmission module 14 is configured to transmit a relay signal during the startup phase of the information control platform, so that the communication devices 2 capable of receiving the relay signal among the communication devices 2 respond to the relay signal and transmit a feedback signal. Specifically, when the second transmission module 14 transmits the relay signal, the signals received by the first communication device 21 include the relay signal and the shore-based signal, and the signals received by the second communication device 22 include the relay signal but do not include the shore-based signal. Therefore, the feedback signal transmitted by the first communication device 21 is different from the feedback signal transmitted by the second communication device 22. Among them, the former feedback signal includes the shore-based signal, while the latter feedback signal does not include the shore-based signal. The reception module 15 is configured to receive the feedback signals of the communication devices, so that the subsequent determination module 11 can determine whether each feedback signal includes the shore-based signal based on the feedback signals of the communication devices 2, so as to determine the types of the communication devices 2.

[0054] It can be understood that during the startup phase of the communication system or the startup phase of the information control platform, the second communication device 22 cannot receive the shore-based signal. Therefore, in the above embodiment, by transmitting the relay signal through the second transmission module 14, the communication devices 2 capable of receiving the relay signal among the communication devices 2 respond to the relay signal and transmit the feedback signal. In this way, the types of each communication device can be determined according to the feedback signal. It should be noted that in some embodiments, the determination module 11 can also determine the types of the communication devices 2 based on the current azimuth information of the communication devices 2, the azimuth information of the shore-based base station, and the distance information between the communication devices 2 and the shore-based base station.

[0055] Figure 7 It is another exemplary modular structure diagram of the information control platform. As Figure 7 shown, in some alternative embodiments, in addition to the second transmission module 14, the reception module 15, the determination module 11, the analysis module 12, and the first transmission module 13, the information control platform further includes a monitoring module 16. Among them, the monitoring module 16 is configured to monitor the signal parameters of the shore-based signal received by the current target communication device. As described above, the signal parameters include one or more of signal strength, signal-to-noise ratio, signal phase, signal delay time, bit error rate, frame error rate, etc. The analysis module 12 is further configured to re-analyze the signal parameters of the shore-based signals received by the first communication devices 21 in response to the signal parameters of the shore-based signal received by the current target communication device not meeting the first preset condition, and determine one of the first communication devices 21 as the target communication device.

[0056] Exemplarily, taking the signal parameter as the signal strength as an example, the working processes of the above-mentioned monitoring module 16 and analysis module 12 will be introduced. When the signal parameter is the signal strength, the first preset condition is that the signal strength of the shore-based signal is not less than the first preset value. At this time, the monitoring module 16 is configured to monitor the signal strength of the shore-based signal; when the signal strength of the shore-based signal received by the analysis module 12 is less than the first preset value, that is, when the signal quality of the shore-based signal deteriorates, the analysis module 12 re-analyzes and scores the signal strengths of the shore-based signals received by each first communication device 21, and takes the first communication device 21 with the highest signal strength as the new target communication device.

[0057] In the above embodiment, by using the monitoring module to monitor the signal parameters of the shore-based signals received by the target communication device in real time, when it is detected that the signal quality of the shore-based signal received by the current target communication device deteriorates, the analysis module can re-analyze each shore-based signal in time, and re-determine the shore-based signal with the best quality from them, and take the first communication device corresponding to the shore-based signal as the new target communication device. In this way, it can be ensured that when the communication device moves or the weather environment changes, resulting in a decrease in the quality of the base station signal received by the current target communication device, the tracking target of the second communication device is switched to the first communication device with the best signal quality, so as to ensure the high quality and high stability of the shore-based signal received by the second communication device.

[0058] Figure 8 It is a specific functional schematic diagram of the monitoring module. As Figure 8 shown, in some examples, the monitoring module 16 is further configured to monitor the signal parameters of the signals received by each communication device 2, and issue a warning signal when the signal parameter of the signal received by any communication device 2 is less than the first threshold. Still taking the signal parameter as the signal strength as an example to introduce the working process of the monitoring module 16, when the signal parameter is the signal strength, the first threshold represents the minimum signal strength required for the communication device to communicate normally. When the signal strength is less than this first threshold, it indicates that the communication device is disconnected; at this time, the work content of the monitoring module 16 is: monitor the signal strengths of the signals received by each communication device 2, and when it is detected that the signal strength of any one is less than the first threshold, that is, when it is detected that the communication device 2 is disconnected, a warning signal is issued to prompt the operator to perform manual intervention.

[0059] Continue to refer to Figure 8, in some examples, the monitoring module 16 is further configured to monitor the signal parameters of the shore-based signals received by each of the first communication devices 21; correspondingly, the analysis module 12 is further configured to, in response to the signal parameters of the shore-based signals received by any one of the first communication devices 21 not meeting the third preset condition, generate a first adjustment instruction based on the orientation information of each of the first communication devices 21 and its target base station; the first communication device 21 adjusts its parameters in response to the first adjustment instruction to adjust the signal parameters of the shore-based signals it receives.

[0060] Next, in combination with the structure of the first communication device, the above working processes of the monitoring module and the analysis module will be specifically introduced.

[0061] Figure 9 is an exemplary structural schematic diagram of the first communication device. As Figure 9 shown, the first communication device 21 includes: a plurality of first antenna units 211, a first chasing station module 212, and a first signal conversion module 213. Among them, the plurality of first antenna units 211 form a multi-sector antenna, and the radiation area of each antenna unit 211 is different. Taking a six-sector antenna as an example, the radiation range of each antenna unit is 60°. The first chasing station module 212 is configured to determine the target base station of the first communication device 21 according to the orientation information of the first communication device 21 and each shore-based base station, and is configured to, in response to the first adjustment instruction, determine one of the first antenna units 211 as the target first antenna unit based on the signal parameters of the base station signals received by each of the first antenna units 211 from its target base station, communicatively connect the target first antenna unit to its target base station, and send the signal of the target base station received by the target first antenna unit to the analysis module 12 of the information control platform as the shore-based signal received by the first communication device 21. The first signal conversion module 213 is configured to convert the target base station signal received by the target first antenna unit for the user terminal to access.

[0062] Combined with Figure 8 and Figure 9, introduce the specific working processes of the first communication device, the monitoring module, and the analysis module. Still taking the signal parameter as the signal strength as an example, the above-mentioned third preset condition means that the signal strength is greater than the third preset value. In the first stage, multiple antenna units 211 of the first communication device 21 start scanning and upload the shore-based signals they scan to the information control platform. At the same time, the first determination module 212 of the first communication device 21 determines the target base station of the first communication device 21; the monitoring module 16 monitors the shore-based signals scanned by the first communication device. When the intensity of the monitored shore-based signal is less than the third preset value, the analysis module 12 issues a first adjustment instruction; when the first communication device 21 receives the first adjustment instruction, the first determination module 212 determines one of the first antenna units 211 as the target first antenna unit based on the signal parameters of the base station signals received by each first antenna unit 211 from its target base station, communicatively connects the target first antenna unit to its target base station, and uploads the base station signal received by the target first antenna unit to the information control platform as the shore-based signal received by the first communication device 21. It can be understood that the target base station usually refers to the base station closest to the communication device.

[0063] Figure 10 is another exemplary structural schematic diagram of the first communication device. As Figure 10 shown, the first communication device 21 includes: a first directional antenna 214, a first control module 215, and a first signal conversion module 213. Among them, the first control module 215 is configured to determine the target base station of the first communication device 21 based on the orientation information of the first communication device 21 and each shore-based base station; and is configured to, in response to the first adjustment instruction, determine the target angle of the first directional antenna 214 based on the signal parameters of the base station signals received by the first directional antenna 214 at different angles from its target base station, rotate the first directional antenna 214 to the target angle, communicatively connect it to its target base station; and upload the target base station signal received by the first directional antenna 214 at the target angle to the information control platform as the shore-based signal received by the first communication device 21. The first signal conversion module 213 is configured to convert the target base station signal received by the first directional antenna 214 at the target angle for the user terminal to access.

[0064] Combined with Figure 8 and Figure 10, introduce the specific working processes of the first communication device, the monitoring module, and the analysis module. Still taking the signal parameter as the signal strength as an example, the above third preset condition means that the signal strength is greater than the third preset value. In the first stage, the first directional antenna 214 of the first communication device 21 starts to scan and uploads the shore-based signals it scans to the information control platform. At the same time, the first control module 215 of the first communication device 21 determines the target base station of the first communication device 21; the monitoring module 16 monitors the shore-based signals scanned by the first communication device. When the intensity of the monitored shore-based signal is less than the third preset value, the analysis module 12 issues a first adjustment instruction; when the first communication device 21 receives the first adjustment instruction, the first control module 215 determines the target angle of the first directional antenna 214 according to the signal strength of its target base station received by the first directional antenna 214 at different angles, rotates the first directional antenna 214 to the target angle and communicates with its target base station, and uploads the base station signals it receives to the information control platform as the shore-based signals received by the first communication device 21.

[0065] In the above example, by monitoring the signal parameters of the shore-based signals received by each first communication device in real time through the monitoring module, when the signal quality of the shore-based signal is detected to decline, an adjustment instruction can be issued to the first communication device, so that each first communication device adjusts its parameters, selects the best antenna unit or rotates the directional antenna to the best angle and then communicates with the target base station. At this time, it can ensure that the shore-based signals uploaded by each first communication device 21 to the information control platform maintain high quality and high stability, so as to ensure that the second communication device 22 can continuously track high-quality shore-based signals and improve the communication efficiency and communication quality of the communication system.

[0066] Still referring to Figure 8 , in some examples, the monitoring module 16 is further configured to monitor the signal parameters of the signals received by each second communication device 22; correspondingly, the analysis module 12 is further configured to generate a second adjustment instruction based on the azimuth information of each second communication device 21 and the main communication device 1 in response to the signal parameters of the signals received by any one of the second communication devices 21 not meeting the fourth preset condition; the second communication device 22 adjusts its parameters in response to the second adjustment instruction to adjust the signal parameters of the signals it receives.

[0067] Next, combined with the structure of the second communication device, the above working processes of the monitoring module and the analysis module will be specifically introduced.

[0068] Figure 11 is an exemplary structural schematic diagram of the second communication device. As Figure 11As shown in the figure, the second communication device 22 includes: a plurality of second antenna units 221, a second tracking station module 222, and a second signal conversion module 223. Among them, the plurality of second antenna units 221 form a multi-sector antenna, and the radiation area of each antenna unit 221 is different. Taking a six-sector antenna as an example, the radiation range of each antenna unit is 60°. The second tracking station module 222 is configured to, in response to a second adjustment instruction, determine one of the second antenna units 221 as a target second antenna unit based on the signal parameters of the signals received by each second antenna unit 221, and communicatively connect the target second antenna unit to the main communication device 1. The second signal conversion module 223 is configured to convert the shore-based signal received by the target second antenna unit for access by the user terminal.

[0069] Combined with Figure 8 and Figure 11 , the specific working processes of the second communication device, the monitoring module, and the analysis module are introduced. Still taking the signal strength as the signal parameter, the above-mentioned fourth preset condition means that the signal strength is greater than the fourth preset value. In the first stage, the multiple antenna units 221 of the second communication device 22 start scanning and upload the signals they scan to the information control platform; the monitoring module 16 monitors the signals scanned by the second communication device 22. When the monitored signal strength is less than the fourth preset value, the analysis module 12 issues a second adjustment instruction; when the second communication device 22 receives the second adjustment instruction, the second tracking station module 222 determines one of the second antenna units 221 as a target second antenna unit based on the signal parameters of the signals received by each second antenna unit 221, and communicatively connects the target second antenna unit to the main communication device 1.

[0070] Figure 12 is another exemplary structural schematic diagram of the second communication device. As Figure 12 shown, the second communication device 22 includes: a second directional antenna 224, a second control module 225, and a second signal conversion module 223. Among them, the second control module 225 is configured to, in response to a second adjustment instruction, determine the target angle of the second directional antenna 224 based on the signal parameters of the signals received by the second directional antenna 224 at different angles, rotate the second directional antenna 224 to the target angle, and communicatively connect it to the main communication device 1. The second signal conversion module 223 is configured to convert the shore-based signal sent by the information control platform received by the second directional antenna 224 at the target angle for access by the user terminal.

[0071] Combined with Figure 8 and Figure 12, introduce the specific working processes of the second communication device, the monitoring module, and the analysis module. Still taking the signal parameter as the signal strength as an example, the above fourth preset condition means that the signal strength is greater than the fourth preset value. In the first stage, the second directional antenna 224 of the second communication device 22 starts to scan and uploads the signals it scans to the information control platform; the monitoring module 16 monitors the signals scanned by the second communication device 22. When the signal strength is detected to be less than the fourth preset value, the analysis module 12 issues a second adjustment instruction; when the second communication device 22 receives the second adjustment instruction, the second control module 225 determines the target angle of the second directional antenna 224 according to the signal strength of the signals received by the second directional antenna 224 at different angles, rotates the second directional antenna 224 to the target angle, and then communicates with the main communication device 1 to receive the shore-based signal sent by the information control platform.

[0072] In the above example, by monitoring the signal parameters of the signals received by each second communication device in real time through the monitoring module, when the signal quality deteriorates, an adjustment instruction can be issued to the second communication device, so that each second communication device adjusts its parameters, selects the best antenna unit, or rotates the directional antenna to the best angle and then communicates with the main communication device. At this time, it can be ensured that each second communication device 22 can effectively and continuously receive high-quality and high-stability shore-based signals, improving the communication efficiency and communication quality of the communication system.

[0073] In addition, in some alternative embodiments, the monitoring module 16 includes an environmental monitoring unit for real-time monitoring of the marine environment, such as satellite positioning location and hydro-meteorological information, etc. When the monitoring module 16 issues the first adjustment instruction, it simultaneously sends the current marine environment information to the first communication device 21; the first control module 215 responds to the first adjustment instruction, receives the current marine environment information, and determines the target angle of the first directional antenna 214 based on the marine environment information and the signal strength of the signals received by the first directional antenna 214 at different angles from its target base station, rotates the first directional antenna 214 to the target angle, and then communicates with its target base station. Similarly, when the monitoring module 16 issues the second adjustment instruction, it simultaneously sends the current marine environment information to the second communication device 22; the second control module 225 responds to the second adjustment instruction, receives the current marine environment information, and determines the target angle of the second directional antenna 224 based on the marine environment information and the signal strength of the signals received by the second directional antenna 214 at different angles, rotates the second directional antenna 224 to the target angle, and then communicates with the main communication device 1.

[0074] In some alternative embodiments, the first communication device 21 and the second communication device 22 further include a LoRa communication module. As a backup communication method, the LoRa communication module is configured to connect the first communication device 21 and the second communication device 22 through the LoRa communication module when the second communication device 22 is disconnected from the main communication device 1, so that the first communication device 21 can send a signal to the second communication device 22.

[0075] In some alternative embodiments, the first communication device 21 and the second communication device 22 further include a data storage unit. The data storage unit is configured to store historical signal data, historical environmental characteristics, switching instructions, etc. of the communication device, so that when the current environmental information, orientation information, or signal parameters are the same as the historical ones, there is no need for repeated calculation, and the historical saved data can be directly referred to to obtain the current control instruction, so as to quickly switch to the target antenna unit or target angle.

[0079] Step S102, through the analysis module 12, analyze the signal parameters of the shore-based signals received by each first communication device 21 to determine one of the first communication devices 21 as the target communication device.

[0080] Step S103, through the first transmission module 13, send the shore-based signal received by the target communication device to the second communication device 22.

[0081] In some alternative embodiments, before step S101, the communication method further includes:

[0082] Step S01: Send a relay signal through the second sending module 14 so that the communication devices 2 capable of receiving the relay signal among the communication devices 2 respond to the relay signal and send a feedback signal.

[0083] Step S02: Receive the feedback signals of the communication devices 2 through the receiving module 15.

[0084] In some other alternative embodiments, the communication method further includes:

[0085] Step S102a: Monitor the signal parameters of the shore-based signal received by the target communication device through the monitoring module 16.

[0086] Step S102b: When the signal parameters of the shore-based signal received by the current target communication device do not meet the first preset condition, use the analysis module 12 to re-analyze the signal parameters of the shore-based signals received by the first communication devices 21, and determine one of the first communication devices 21 as the target communication device.

[0087] In some other alternative embodiments, the communication method further includes:

[0088] Monitor the signal parameters of the signals received by the communication devices 2 through the monitoring module 16, and send a warning signal when the signal parameters of the signals received by any communication device 2 are less than the first threshold.
