[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 conjunction 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 computer 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, extracts feature information according to the communication analysis model under different sea conditions, and obtains control instructions based on the feature information from the preset control instruction table based on the feature information of the shore-based computer. According to the communication analysis model under different sea conditions, a suitable 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 the 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 a suitable communication method to execute the control instruction.

[0040] Furthermore, the communication analysis model under the above-mentioned 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 condition 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, and the method for adaptively sensing sea conditions based on a cross-domain communication gateway is continued to be executed by installing in a control unit of the cross-domain communication gateway, and 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 may be a shore-based computer or a cross-domain communication gateway, or an underwater unmanned node. In practical applications, a cross-domain communication gateway running a method for adaptively sensing sea conditions based on a cross-domain communication gateway may 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 to run 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. Perform ocean monitoring of the equipment working condition of each ocean monitoring device to determine whether the ocean monitoring equipment can 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. Further, it can be judged whether the equipment to be detected is in a normal state according to whether the equipment temperature information is in a preset temperature range, and whether the equipment humidity information is in a preset humidity range, and whether the equipment program runs normally. If the equipment temperature information is in the preset temperature range, and the equipment humidity information is in the preset humidity range, and the equipment program runs 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 continue to execute the subsequent steps.

[0045] If it is determined that there is an abnormality in the internal equipment, the marine monitoring equipment repair work is carried out, and the analysis and diagnosis are carried out according to the cause of the equipment failure. For example, for a certain equipment, if the equipment condition information is abnormal, the equipment temperature information and the equipment humidity information are within the corresponding range, the abnormal cause is determined to be a program failure according to the corresponding diagnosis rule of this type; if the equipment condition information is abnormal, the equipment temperature information is higher than the corresponding range, and the equipment humidity information is within the corresponding range, the abnormal cause is determined to be a high temperature abnormality according to the corresponding diagnosis rule; if the equipment condition information is abnormal, the equipment humidity information is higher than the corresponding range, and the equipment temperature information is within the corresponding range, the abnormal cause is determined to be a moisture abnormality according to the corresponding diagnosis rule. After obtaining the analysis and judgment results of the equipment abnormality, the repair work is carried out. If the abnormal cause is a program failure, a repair control instruction can be sent to restart the abnormal equipment so that the program returns to normal; if the abnormal cause is a high temperature abnormality, an exhaust control instruction can be sent to control the fan corresponding to the abnormal equipment to exhaust, so that the temperature returns to normal. If the abnormal cause is a moisture abnormality, a dehumidification instruction can be sent to control the dehumidification instrument to dehumidify, so as to restore 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 device.

[0046] After detecting that the working conditions of the ocean monitoring equipment configured by the cross-domain communication gateway are all normal, the cross-domain communication gateway control unit obtains the ocean monitoring information obtained by the ocean monitoring equipment configured by the cross-domain communication gateway for 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 marine monitoring information, the cross-domain communication gateway control unit performs adaptive processing of the sea condition information to obtain characteristic information, obtains the communication mode corresponding to the characteristic information from the preset communication mode selection table under different sea conditions, and obtains the control information corresponding to the characteristic information from the preset control configuration table. After obtaining the control information, the cross-domain communication gateway sends the control information to the shore-based computer or performs self-control processing according to 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 to obtain monitoring information is as follows: Figure 3As shown, the cross-domain communication gateway obtains offshore wind speed and direction information through wind speed and direction instruments, obtains buoy motion inertial parameters through inertial sensors, obtains light intensity information through light sensors, and obtains wave information through wave sensors. After the cross-domain communication gateway obtains ocean monitoring information, it transmits it to the control unit for analysis and processing, analyzes wind speed and direction information, and obtains control instructions and executes self-control commands by analyzing inertial sensor data to obtain buoy motion posture, and comprehensively analyzes wind speed and direction information, light information, inertial information, and wave information to obtain sea condition level. After the analysis of ocean monitoring information is completed, 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 condition 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, and 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 the 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 transmit 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] Furthermore, the energy management module includes components such as a battery, a voltage conversion device, an STM32 microcontroller, and a relay. The battery is responsible for providing energy supply. The voltage conversion device includes a 3.3V voltage conversion board, a 5V voltage conversion board, a 12V voltage conversion board, and a 24V voltage conversion board. The battery can stably output 3.3V, 5V, 12V, and 24V voltages through the voltage conversion device. Writing the burning program code can download the power supply control instruction information in the STM32 microcontroller, and the power supply can be orderly controlled through the relay, and the battery power information can be obtained at the same time.

[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, data transmission radio and other communication equipment. The water communication module realizes information exchange with the control unit module through wired communication.

[0053] The dry end of the underwater communication module is located inside the cross-domain communication gateway, and the wet end of the underwater communication module is located in the seawater area with a fixed depth. The two communicate through watertight cables. The dry end of the underwater communication module has two communication forms: spread spectrum and OFDM modulation, using ARM and DSP to realize the corresponding signal modulation respectively. The wet end of the underwater communication module realizes the conversion between electrical signals and acoustic signals.

[0054] The data management module is responsible for storing ocean monitoring information, results of analysis and processing by 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 information interaction between the above-water and underwater communication modules, the storage, analysis and forwarding of data information, the acquisition of ocean monitoring information, and the normal execution of the buoy operation control mechanism such as the program code running 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 installed 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 adaptively sensing sea conditions 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 environmental information processing method based on the shore-based computer, 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 environmental information processing method of the base computer, 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 illumination 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 through Beidou communication method, mobile communication method, digital radio communication method, underwater acoustic communication method or several of them for reporting. The shore-based computer replies confirmation information to the cross-domain communication gateway. If the cross-domain communication gateway does not receive the confirmation information or the confirmation information 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.
