[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0037] The air-sea cross-domain robust communication method with adaptive sea condition perception provided by the example of the present invention mainly includes two parts: an environmental information processing method based on a shore-based computer and a sea condition adaptive perception method based on a cross-domain communication gateway. Through their combined effect, the robustness of the air-sea cross-domain communication is improved.

[0038] According to some embodiments of the present invention, an environmental information processing method based on a shore-based computer is applied to a shore-based computer. The environmental information processing method based on a shore-based computer runs in the shore-based computer, and establishes a network connection with a cross-domain communication gateway through one or more of Beidou communication mode, mobile communication mode, digital radio communication, and underwater acoustic communication to realize wireless transmission of data information.

[0039] The implementation process of the environmental information processing method based on shore-based computers provided by the embodiment of the present invention is as follows: Figure 1As shown, the cross-domain communication gateway is deployed in the designated sea area and powered on. The shore-based computer first checks the status of the communication equipment. If the communication equipment is abnormal, the equipment is repaired. If the communication equipment is normal, the shore-based computer collects the sea condition information of the sea area where the communication link between the shore-based computer and the cross-domain communication gateway is located through news, meteorological platforms and other channels, analyzes the collected sea condition information, and extracts feature information according to the communication analysis model under different sea conditions. Based on the feature information, the preset control instruction table based on the feature information of the shore-based computer obtains the control instruction according to the feature information. According to the communication analysis model under different sea conditions, the appropriate communication method is selected to send the feature information and the air-sea cross-domain communication control instruction to the air-sea cross-domain communication gateway. The air-sea cross-domain communication gateway receives the feature information and control instruction. If the cross-domain communication gateway has run the environmental information processing method of the base computer, the cross-domain communication gateway corrects the environmental monitoring data according to the feature information, analyzes the environmental status of the communication link based on the feature information, and selects the appropriate communication method to execute the control instruction.

[0040] Furthermore, the communication analysis model under different sea conditions is constructed through empirical models and mathematical model formulas. The input parameters of the communication analysis model under different sea conditions include communication mode, wind speed and direction at sea, sea surface waves, sea temperature and salinity, rainfall and sea fog, electromagnetic interference, background noise, and the output parameters are communication mode, sea condition level, characteristic information and sea condition level information.

[0041] Furthermore, the preset control instruction table based on the characteristic information of the shore-based computer is a set of control instruction information pre-set in the shore-based computer according to the sea state level, and the table can be modified in the shore-based computer.

[0042] According to some embodiments of the present invention, a method for adaptively sensing sea conditions based on a cross-domain communication gateway is applied to a cross-domain communication gateway. The method for adaptively sensing sea conditions based on a cross-domain communication gateway is continued to be executed by a control unit installed in the cross-domain communication gateway. The control unit of the cross-domain communication gateway establishes a network connection with an external communication platform through one or more of Beidou communication mode, mobile communication mode, digital radio communication, and underwater acoustic communication to achieve wireless transmission of data information, wherein the external communication platform can be a shore-based computer or a cross-domain communication gateway, or an underwater unmanned node. In actual applications, a cross-domain communication gateway running the method for adaptively sensing sea conditions based on a cross-domain communication gateway can establish a communication connection with a shore-based computer or an underwater unmanned node to achieve transmission of data information.

[0043] The implementation process of the sea state adaptive perception method based on the cross-domain communication gateway provided by the embodiment of the present invention is as follows: Figure 2As shown, the cross-domain communication gateway is powered on and starts running the sea condition adaptive perception method based on the cross-domain communication gateway. The cross-domain communication gateway first checks the working status of the ocean monitoring equipment configured by the cross-domain communication gateway. In particular, the ocean monitoring equipment configured by the cross-domain communication gateway provided by the example of the present invention mainly includes wind speed and direction instruments, inertial sensors, light sensors, and wave sensors. At the same time, each ocean monitoring device is equipped with a temperature sensor and a humidity sensor to check the working condition of the equipment. The equipment working condition ocean monitoring is performed on each ocean monitoring device to determine whether the ocean monitoring equipment can all work normally.

[0044] Furthermore, the equipment operating condition can be used to reflect the working condition of the equipment. The equipment operating condition information can be normal, abnormal or dormant, etc. The equipment operating condition information, equipment temperature information and equipment humidity information of each ocean monitoring equipment can be used to judge whether the equipment is abnormal. Furthermore, whether the equipment to be detected is in a normal state can be judged based on whether the equipment temperature information is within a preset temperature range, and whether the equipment humidity information is within a preset humidity range, and whether the equipment program is running normally. If the equipment temperature information is within the preset temperature range, and the equipment humidity information is within the preset humidity range, and the equipment program is running normally, then the equipment to be detected is judged to be in a normal state, otherwise it is in an abnormal state. If it is judged that each device to be monitored is in a normal state, then it is judged that there is no abnormality in the internal device; if it is judged that any device to be detected is in an abnormal state, then it is judged that there is an abnormality in the internal device. If it is judged that there is no abnormality in the internal device, then the subsequent steps are continued.

[0045] If an internal device abnormality is determined, repair work on the marine monitoring equipment is performed, analyzing and diagnosing the cause of the equipment failure. For example, if the device operating condition information is abnormal, and the device temperature and humidity information are both within the specified ranges, the diagnostic rule for that type of device will determine the cause of the abnormality to be a program failure. If the device operating condition information is abnormal, the device temperature information is above the specified range, and the device humidity information is within the specified range, the diagnostic rule will determine the cause of the abnormality to be a high temperature abnormality. If the device operating condition information is abnormal, the device humidity information is above the specified range, and the device temperature information is within the specified range, the diagnostic rule will determine the cause of the abnormality to be moisture abnormality. After obtaining the results of the device abnormality analysis, repair work is performed. If the cause of the abnormality is a program failure, a repair control command can be sent to restart the abnormal device, thereby restoring normal operation. If the cause of the abnormality is a high temperature abnormality, an exhaust control command can be sent to control the fan corresponding to the abnormal device to exhaust air, thereby restoring the temperature to normal. If the cause of the abnormality is moisture abnormality, a dehumidification command can be sent to control the dehumidification device to dehumidify, thereby restoring the humidity to normal. If the working condition of the ocean monitoring equipment does not return to normal after being repaired by the control command, a control command is sent to start an alternative equipment.

[0046] After detecting that the operating conditions of the ocean monitoring equipment configured by the cross-domain communication gateway are all normal, the cross-domain communication gateway control unit obtains ocean monitoring information obtained by the ocean monitoring equipment configured by the cross-domain communication gateway through external monitoring. Further, the ocean monitoring information includes offshore wind speed and direction parameters, buoy motion inertia information, light intensity information, and wave observation information. After obtaining the ocean monitoring information, the cross-domain communication gateway control unit performs adaptive processing of the ocean condition information to obtain characteristic information, obtains the communication mode corresponding to the characteristic information from a preset communication mode selection table for different ocean conditions, and obtains control information corresponding to the characteristic information from a preset control configuration table. After obtaining the control information, the cross-domain communication gateway sends the control information to a shore-based computer or performs self-control processing based on the control information.

[0047] According to some embodiments of the present invention, the process of the ocean monitoring device configured by the cross-domain communication gateway obtaining monitoring information is as follows: Figure 3As shown, the cross-domain communication gateway obtains offshore wind speed and direction information from wind speed and direction instruments, obtains buoy motion inertial parameters from inertial sensors, obtains light intensity information from light sensors, and obtains wave information from wave sensors. After receiving ocean monitoring information, the cross-domain communication gateway transmits it to the control unit for analysis and processing. The control unit analyzes wind speed and direction information and light information to obtain control instructions and execute autonomous control commands. The inertial sensor data is analyzed to obtain the buoy's motion posture. A comprehensive analysis of wind speed and direction information, light information, inertial information, and wave information is used to determine the sea state level. After the ocean monitoring information is analyzed, the analysis structure is sent to the shore-based computer for reporting.

[0048] According to some embodiments of the present invention, the process of adaptively processing sea state information based on ocean monitoring information is as follows: Figure 4 As shown, the cross-domain communication gateway control unit first obtains ocean monitoring information (wind speed and direction information, high-precision pitch information, high-precision roll information, high-precision azimuth measurement information, solar radiation information, wave height information, wave period information, wave direction information), and then the cross-domain communication gateway control unit analyzes the wind speed and direction information, determines the current level according to the preset wind speed and direction classification table, obtains the control command according to the preset control table, and executes the control command. The cross-domain communication gateway control unit analyzes the solar radiation information, determines the current level according to the preset solar radiation classification table, and obtains the control command according to the preset control table. Get control commands and execute control commands. The cross-domain communication gateway control unit analyzes high-precision pitch information, high-precision roll information, high-precision azimuth measurement information, analyzes the current motion posture of the cross-domain communication gateway, and obtains control commands according to the preset control table, and executes control commands. The cross-domain communication gateway control unit comprehensively analyzes ocean monitoring information (wind speed and direction information, high-precision pitch information, high-precision roll information, high-precision azimuth measurement information, solar radiation information, wave height information, wave period information, wave direction information) to obtain the current sea conditions and transmits the analysis results back to the shore-based computer.

[0049] In some embodiments provided by the present invention, the structure of the sea state adaptive sensing device based on the cross-domain communication gateway is as follows: Figure 5 As shown, the sea condition adaptive perception device based on the cross-domain communication gateway mainly includes an energy management module, an ocean monitoring module, an above-water communication module, an underwater communication module, a data management module and a control unit module.

[0050] The energy management module further includes components such as a battery, a voltage converter, an STM32 microcontroller, and relays. The battery provides energy, while the voltage converter includes 3.3V, 5V, 12V, and 24V converter boards. Through the converters, the battery can output stable voltages of 3.3V, 5V, 12V, and 24V. Programming code downloads power supply control instructions to the STM32 microcontroller, controls the power supply in an orderly manner through relays, and simultaneously obtains battery charge information.

[0051] The ocean monitoring module includes the above-mentioned wind speed and direction meter, inertial sensor, light sensor and wave sensor.

[0052] The water communication module includes Beidou communication positioning terminal, mobile communication terminal, digital radio and other communication equipment. The water communication module realizes information exchange with the control unit module through wired communication.

[0053] The underwater communication module's dry end is located within the cross-domain communication gateway, while the underwater communication module's wet end is located in seawater at a fixed depth. The two communicate via a watertight cable. The underwater communication module's dry end supports two communication modes: spread spectrum and OFDM modulation, using ARM and DSP for signal modulation, respectively. The underwater communication module's wet end converts electrical and acoustic signals.

[0054] The data management module is responsible for storing ocean monitoring information, analysis and processing results of the control unit module, communication history records, preset wind speed and direction classification tables, preset solar radiation classification tables and preset control tables.

[0055] The control unit module is responsible for realizing the normal execution of the buoy operation control mechanism, such as information interaction with the surface and underwater communication modules, storage, analysis and forwarding of data information, acquisition of ocean monitoring information, and program code execution of the sea condition adaptive perception method based on the cross-domain communication gateway.

[0056] Furthermore, the sea condition adaptive sensing device based on the cross-domain communication gateway should be a part of the cross-domain communication gateway and be assembled in the cross-domain communication gateway.

[0057] In some embodiments of the present invention, the application scenario of the air-sea cross-domain robust communication method for adaptive sea state perception provided by the example of the present invention is as follows: Figure 6 As shown:

[0058] During the operation of the air-sea cross-domain robust communication method for adaptive sea condition perception, the cross-domain communication gateway is deployed in the designated sea area and powered on. The shore-based computer first runs the shore-based computer-based environmental information processing method and sends characteristic information and control instructions to the cross-domain communication gateway through one or more of the Beidou communication method, mobile communication method, digital radio communication method, and underwater acoustic communication method. If the cross-domain communication gateway has not run the computer-based environmental information processing method, the cross-domain communication gateway completes the environmental monitoring data initialization operation according to the characteristic information. If the cross-domain communication gateway has run the computer-based environmental information processing method, the cross-domain communication gateway corrects the environmental monitoring data according to the characteristic information. After the cross-domain communication gateway completes the characteristic information processing, it executes the control instruction.

[0059] The cross-domain communication gateway control unit runs the sea condition adaptive perception method based on the cross-domain communication gateway. It will first obtain the wind speed and direction control instructions for self-control processing, and then obtain the lighting control instructions for self-control processing, obtain the current motion posture of the cross-domain communication gateway, and obtain the control command according to the preset control table, and execute the control command, comprehensively analyze the ocean monitoring information, obtain the communication method corresponding to the characteristic information from the preset communication method selection table under different sea conditions, and transmit the analysis results back to the shore-based computer for reporting through one or more of the Beidou communication method, mobile communication method, digital radio communication method, and underwater acoustic communication method. The shore-based computer replies with a confirmation message to the cross-domain communication gateway. If the cross-domain communication gateway does not receive the confirmation message or the confirmation message is wrong, the data will be retransmitted. The shore-based computer can also send control commands to the cross-domain communication gateway to actively obtain ocean monitoring information, wind speed and direction levels, solar radiation conditions, wave observation information, and ocean monitoring information analysis results.
