[0002] Air-sea cross-domain communication is a key issue in the current field of ocean observation. Since electromagnetic waves attenuate very severely in water and sound waves cannot break through the sea surface to be transmitted to the water, communication under the traditional signal frequency band needs to be achieved with the help of relay nodes. The air-sea cross-domain communication gateway effectively solves this problem. As a relay node, it supports multiple modes of communication such as hydroacoustic, electromagnetic or optical. The air-sea cross-domain communication gateway can form an ocean observation system with multiple nodes such as satellites, underwater robots, buoys and surface ships. At present, the air-sea cross-domain communication gateway is usually powered by batteries, and some are supplemented by energy existing in various environments such as solar energy and wind energy. However, the traditional power generation efficiency is too low to generate sufficient energy for the air-sea cross-domain communication gateway system to work for a long time.

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] The present invention proposes a self-drifting air-sea cross-domain communication gateway system for clean energy supply and monitoring. The system has two power generation methods: wind energy collection and solar energy collection. The system can automatically adjust energy collection and use measures according to the power generation conditions of the gateway system, thereby improving the energy utilization rate of the gateway system, solving the technical problems of stable energy collection and utilization of the gateway system, providing an efficient, stable and reliable energy supply solution, and extending the working time of the gateway system.

[0016] Reference Figure 1-Figure 4, the example of this application provides a self-drifting air-sea cross-domain communication gateway system for clean energy supply and monitoring. This technology utilizes the wind-driven blade rotation of a spiral vertical turbine generator and the absorption of solar energy by flexible solar panels, and can convert wind energy and solar energy into electrical energy. It includes: a communication subsystem, an energy collection subsystem, an environmental perception subsystem, an adaptive power generation control subsystem, an electronic compartment and a floating body. The communication subsystem includes: a communication equipment module, a main control unit module and a communication antenna. The communication equipment module includes: a digital radio communication terminal, a hydroacoustic communication terminal dry end, a hydroacoustic communication terminal wet end and an Iridium communication terminal. The communication equipment module is connected to the main control unit module by wire, and the main control unit module is responsible for realizing information interaction with the outside world through the communication equipment module. The communication antenna is connected to the communication equipment module by wire. The communication subsystem, the energy collection subsystem and the environmental perception subsystem are all connected to the adaptive power generation control subsystem by wire.

[0017] The communication equipment module, the main control unit module and the adaptive power generation control subsystem are all fixedly connected in the electronic compartment. The environmental perception subsystem includes: an environmental monitoring sensor and an STM32F103C8T6 single-chip microcomputer; the environmental monitoring sensor is fixedly connected to the energy collection subsystem; the STM32F103C8T6 single-chip microcomputer is fixedly connected to the electronic compartment; the floating body is set outside the electronic compartment to provide buoyancy support for the gateway system. The energy collection subsystem and the communication antenna are both connected to the top of the floating body.

[0018] It can be understood that the electronic compartment is used to place the environmental perception subsystem, the main control unit module, the Iridium communication terminal, the dry end of the hydroacoustic communication terminal, and some modules of the adaptive power generation control subsystem (except the flexible solar panels and the spiral vertical turbine generator). The flexible solar panels are evenly installed on the upper part of the floating body. The wet end of the hydroacoustic communication terminal is located below the gateway system, which is used to realize the conversion of electrical signals and acoustic signals, and communicate with the dry end of the hydroacoustic communication terminal through watertight cables. The water communication module includes communication equipment such as digital radio stations and Iridium communication terminals. The water communication module realizes information exchange with the main control unit module through wired connection. The dry end of the underwater communication module includes two communication modulation methods: spread spectrum and OFDM, and uses ARM and DSP to realize the modulation and demodulation of the corresponding signals respectively.

[0019] The spiral vertical turbine generator in the energy collection subsystem is located at the top layer of the air-sea cross-domain communication gateway, and the antenna parts of the Iridium communication terminal and the data transmission radio terminal are both located at the inner center of the spiral vertical turbine generator. It can be understood that the air-sea cross-domain communication gateway adopts a vertical hierarchical topology as a whole, and the mechanical layout is based on the energy collection efficiency and functional coupling characteristics. The top communication layer includes the data transmission radio and the Iridium antenna, which are located in the inner center fixing hole of the spiral vertical turbine generator.

[0020] The energy collection subsystem is used to convert solar energy and wind energy into electrical energy; specifically, the energy collection subsystem includes: a solar energy collection module and a wind energy collection module; the solar energy collection module includes: a flexible solar panel; the wind energy collection module includes: a spiral vertical turbine generator. The spiral vertical turbine generator includes: a control system, a tower, a generator, a fixed shaft, and a plurality of Savonius rotor blades connected to the fixed shaft. The tower is connected to the top of the floating body; the generator and the control system are both connected to the tower; the fixed shaft is connected to the generator drive; a plurality of Savonius rotor blades are arranged in an array with the fixed shaft as the center, and the Savonius rotor blades are a semi-drum structure; the generator is connected to the control system line.

[0021] It should be explained in detail that the energy collection subsystem is a spiral vertical turbine wind turbine generator configured on the upper layer of the gateway system, and a flexible solar panel is installed on the upper part of the floating body. The spiral vertical turbine wind turbine generator is fixed on the top cover of the equipment. It is a wind power generation device that uses Savonius rotor modules for power generation. The Savonius rotor blades are semi-drum-shaped, vertically connected to each other along the axis, and the two blades are located in the center of the component. The structure of the vertical axis wind turbine (VAWT) is simpler. Compared with the horizontal axis wind turbine (HAWT), it does not need to face the wind, but can also receive wind energy from the longitudinal and lateral directions, improving the stability of power generation. The flexible solar panel is directly installed on the floating body to absorb solar energy stably. The floating body of the core bearing layer adopts a curvature shell shape with a raised dome at the middle end. The connection of each module extends a 20mm annular flange, which is matched with an O-ring and a 304 stainless steel threaded clamping device to achieve IP68 waterproof standards. The wind turbine is fixed on the top of the gateway system, and the blade curvature is optimized by aerodynamics to ensure low wind speed (≥3m / s) startup. The flexible solar panels are wrapped around the raised upper layer of the dome at the middle end of the floating body, which can ensure that the flexible solar panels can absorb solar energy stably.

[0022] The process of converting solar energy into electrical energy includes three main stages: the first stage is the photovoltaic conversion stage, in which solar panels absorb sunlight and convert light energy into direct current through the photovoltaic effect; the second stage is the power adjustment stage, in which the direct current output of the solar generator is converted into direct current of stable specifications through a voltage stabilizing module; the third stage is the power application stage, in which the converted direct current is directly supplied to the gateway system for use, and the excess power is stored in the battery.

[0023] The process of converting wind energy into electrical energy includes two main stages: the first stage is the conversion of wind energy into mechanical energy through the special design of the asymmetric cross-section of the Savonius rotor blades; the second stage is the conversion of mechanical energy into electrical energy by the generator; the third stage is the power application stage, in which the converted DC power is directly supplied to the gateway system for use, and the excess power is stored in the battery.

[0024] Specifically, the environmental perception subsystem is used to collect and transmit environmental information; specifically, the environmental perception subsystem includes: environmental monitoring sensors and STM32F103C8T6 microcontroller; environmental monitoring sensors include: wave energy sensor, GPS position sensor, wind speed and direction sensor and temperature and humidity sensor. The STM32F103C8T6 microcontroller is responsible for obtaining the wave height, wave period, wave direction, wind speed and direction, equipment location and air temperature and humidity information collected by the environmental monitoring sensor.

[0025] It is worth noting that the adaptive power generation control subsystem is used to stabilize the voltage of the electric energy and then supply power to the communication subsystem and the environmental sensing subsystem. Specifically, the adaptive power generation control subsystem includes: a battery, a power conversion module, an STM32F103C8T6 single-chip microcomputer, a relay and a voltage stabilization module.

[0026] It can be understood that the flexible solar panels and spiral vertical turbine generators convert solar energy and wind energy into electrical energy, which is stored in the battery after being processed by the voltage stabilizing module. The battery is used to store and supply energy. The power conversion module includes a 5V voltage conversion board, a 12V voltage conversion board, and a 24V voltage conversion board, which are used to convert the power of the battery into suitable specifications to drive the gateway system to work. The STM32F103C8T6 microcontroller is used to receive the information collected by the environmental perception subsystem and control the output state of the power supply. The main control unit module uses the acquired environmental information for automatic management, and sends the information to the user through the communication subsystem for real-time monitoring and decision-making. The relay is used to realize the power supply switching function of the gateway system.

[0027] In this embodiment, the communication antenna includes: a data transmission radio and an Iridium antenna. The data transmission radio, Iridium antenna, wind speed and direction sensor, and temperature and humidity sensor are all fixedly connected to the central column of the spiral vertical turbine generator, which can ensure good communication and perception efficiency while ensuring power generation.

[0028] According to one embodiment of the present invention, Figure 1 This is a working diagram of the self-drifting air-sea cross-domain communication gateway system for clean energy supply and monitoring in the embodiment of the present application: The self-drifting air-sea cross-domain communication gateway system for clean energy supply and monitoring is first deployed in the designated sea area. After the gateway system is powered on, the battery will directly supply power to the main control unit module. The main control unit module controls the communication subsystem, energy collection subsystem, environmental perception subsystem, and adaptive power generation control subsystem to enter the working mode and complete the initialization configuration.

[0029] At the same time, the energy collection subsystem enters the power generation state under the influence of the external environment, converting wind energy and solar energy into electrical energy. The converted electrical energy is processed by the voltage stabilizing module and output to the battery and power conversion module, so that the environmental monitoring sensor and the STM32F103C8T6 microcontroller start working. The environmental monitoring sensor transmits the collected environmental information to the STM32F103C8T6 microcontroller, and the STM32F103C8T6 microcontroller controls the startup of the communication equipment module and the transmission of environmental information to the main control unit module by controlling the state of the relay group.

[0030] The battery supplies power to the main control unit module as well as the power conversion module, which is used as energy supplement when the communication equipment module performs high-power communication, maximizing the energy collection and utilization efficiency of the gateway system.

[0031] After the communication subsystem enters the working mode, the gateway system first checks the working condition of the communication equipment. If the communication equipment is working normally, it proceeds to the next step. Otherwise, it repairs the equipment. It determines the cause of the abnormal working condition of the equipment according to the working temperature of the equipment, the power supply of the equipment, and the program running status, and obtains the equipment repair instructions according to the preset communication equipment working condition maintenance table. After the communication equipment works normally, the gateway system and the shore-based computer establish communication connections in sequence through the Iridium communication terminal, the digital radio communication terminal, and the underwater acoustic communication terminal. The shore-based computer sends control instructions to the gateway system. After receiving the control instructions, the gateway system executes related tasks and transmits back the current operating status of the gateway system.

[0032] A schematic diagram of power transmission according to an embodiment of the present invention is shown in FIG. Figure 4 As shown: Solar energy is converted into electrical energy through flexible solar panels, and wind energy is converted into electrical energy through spiral vertical turbine generators. Since the electrical energy generated by the two is not stable, it needs to be stored in the battery and supplied to the power conversion device after voltage stabilization. The electrical energy of the battery will be directly output to the main control unit module to drive the gateway system into working state, and at the same time, part of the electrical energy will be output to the power conversion device as a supplement for the high-power operation of the communication equipment module. The electrical energy converted by the power conversion device will be directly supplied to the STM32F103C8T6 microcontroller and environmental monitoring sensor, so that this part can continue to work during the operation of the gateway system. At the same time, the electrical energy converted by the power conversion device will be supplied to the communication equipment module through the relay group, and the STM32F103C8T6 microcontroller will control the power supply of the communication equipment module by adjusting the on and off of the output of the relay group.

[0033] A schematic diagram of an application scenario of an embodiment of the present invention is shown in FIG. Figure 5 As shown: The air-sea cross-domain communication gateway is used as the first communication terminal, the shore-based computer platform and the underwater equipment are used as the second communication terminal. After the gateway system is deployed in the ocean, it will drift autonomously with the waves. At this time, the environmental perception subsystem continues to work and transmits the collected environmental information or information from the second communication terminal to the shore-based computer platform. At the same time, the wind turbine of the gateway system absorbs wind energy, and the flexible solar panels absorb solar energy. The wind turbine and the flexible solar panels convert wind energy and solar energy into electrical energy, which is stored in the battery pack after processing to ensure that the gateway system can operate stably for a long time in the ocean.

[0034] The present invention converts solar energy and wind energy into electrical energy for the gateway system through hierarchical conversion. The special design of the floating body and the power generation module enables the gateway system to obtain stable energy during the use of the ocean, and the collected energy is preferentially supplied to the environmental perception subsystem, thereby improving the energy utilization efficiency of the entire gateway system and extending the working time of the gateway system. In the present invention, the main control unit module transmits the environmental information obtained by the environmental perception subsystem to the remote monitoring personnel through the communication device module, thereby enhancing the monitoring personnel's ability to identify the environmental status of the air-sea cross-domain communication gateway.

[0035] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
