[0002] Air-sea cross-medium communication is a key issue in the field of ocean observation. Since radio waves attenuate rapidly underwater and sound waves cannot break through the sea surface for transmission, communication under traditional signal frequency bands requires the help of relay nodes.

DETAILED DESCRIPTION

[0012] 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.

[0013] The present invention proposes an adaptive hybrid energy supply air-sea cross-domain communication gateway system which mainly includes a mechanical structure, a communication system, an environmental perception system, and an adaptive marine environment power generation system.

[0014] According to one embodiment of the present invention, the operation process of the adaptive hybrid energy supply air-sea cross-domain communication gateway system of one embodiment of the present invention is as follows: Figure 1 As shown: The adaptive hybrid energy supply air-sea cross-domain communication gateway system is first deployed in the designated sea area and powered on to start automatically and enter the working mode. The communication system, environmental perception system, and adaptive marine environment power generation system enter the working mode to complete the initialization configuration.

[0015] After the communication system enters the working mode, the adaptive hybrid energy supply air-sea cross-domain communication gateway system first checks the working condition of the communication equipment. If the equipment is working normally, it will proceed to the next step and be responsible for equipment repair work. It will judge the cause of abnormal equipment working condition according to the equipment working temperature, equipment power supply condition, and program operation condition, and obtain equipment repair instructions according to the preset communication equipment working condition maintenance table. After the communication equipment works normally, the cross-domain communication gateway and the shore-based computer establish a communication connection through one or more of the Beidou communication terminal, mobile communication terminal, underwater acoustic communication terminal, and digital radio. The shore-based computer sends a control instruction to the cross-domain communication gateway. After receiving the control instruction, the cross-domain communication gateway performs related tasks and transmits back the current cross-domain communication gateway battery power information, power generation module power generation status, and marine environment monitoring parameters.

[0016] After the environmental perception system enters the working mode, it first monitors the working condition of the marine environment monitoring equipment. If it is normal, it proceeds to the next step. If it is abnormal, it performs equipment repair work. In particular, the marine monitoring equipment configured by the cross-domain communication gateway provided in 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 marine monitoring device is equipped with a temperature sensor and a humidity sensor to check the working condition of the equipment. Perform marine monitoring of the equipment working condition of each marine monitoring device to determine whether the marine monitoring equipment can work normally.

[0017] 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.

[0018] After the marine environment monitoring equipment is working normally, the environmental perception system collects wind speed and direction information through the wind speed and direction instrument, and transmits the collected wind speed and direction information to the main control unit for analysis and processing, and obtains the generator fan attitude adjustment instruction. After obtaining the generator fan attitude adjustment instruction, the main control unit sends an attitude instruction control to the wind power generation controller to increase the wind power generation efficiency. Furthermore, the generator fan attitude adjustment includes adjusting the direction of the fan cabin and adjusting the fan blade angle. At the same time, when the generator fan speed is too high, in addition to attitude adjustment, the brake device can also be started to reduce the fan speed.

[0019] The environmental perception system collects solar radiation information through the light sensor, and transmits the collected solar radiation information to the main control unit for analysis and processing, and obtains the solar panel attitude adjustment instruction. After obtaining the solar panel attitude adjustment instruction, the main control unit sends an attitude instruction control to the solar panel controller to increase the efficiency of solar power generation. Furthermore, the solar panel attitude adjustment includes adjusting the direction of the solar panel. At the same time, in order to protect the solar panel in severe sea conditions, the solar panel shielding instruction can also be sent to achieve a protective effect.

[0020] The environmental perception system collects the motion posture information of the cross-domain communication gateway and the sea wave information through inertial sensors and wave sensors, and transmits the collected motion posture information of the cross-domain communication gateway and the sea wave information to the main control unit for analysis and processing, and obtains the attitude adjustment instruction of the surge energy power generation device. After obtaining the attitude adjustment instruction of the surge energy power generation device, the main control unit sends an attitude instruction control to the surge energy power generation device controller to increase the surge energy power generation efficiency. Further, the attitude of the surge energy power generation device includes starting the brake to protect the surge energy power generation device. Further, the surge energy power generation device is a fixed linear reciprocating wave power generation device. The power generation principle of the device is to connect the track where the magnet is installed with the anchor through a rope by adopting an anchoring method, and place them together inside the cross-domain communication gateway. The cross-domain communication gateway where the conductor is placed performs simple harmonic reciprocating motion in the waves, so that the conductor and the magnet on the fixed track produce relative motion, so that the magnetic flux changes to generate induced current. The current enters the battery after being processed by power transmission.

[0021] The adaptive marine environment power generation system enters the working mode. The power generation module enters the working mode under the influence of the external environment. The wind energy, solar energy and surge energy are converted into electrical energy through the power generation module. The electrical energy generated by the power generation module is stored in the battery pack after being processed by power transmission. When the power generation module is in the working mode, it receives the attitude adjustment command and immediately adjusts the attitude to achieve the purpose of increasing power generation efficiency or protecting the power generation device.
