[0053] Compared to the prior art, the hydrogen-oxygen fuel cell power generation method provided in embodiments of the present invention can determine the driving mode of a device with a built-in hydrogen-oxygen fuel cell based on target data. When the driving mode of the device with a built-in hydrogen-oxygen fuel cell is determined to be a closed power generation mode, the control device can activate a first device corresponding to the closed power generation mode. When the driving mode of the device with a built-in hydrogen-oxygen fuel cell is determined to be a normal pressure power generation mode, the control device can activate a second device corresponding to the normal pressure power generation mode. When the driving mode of the device with a built-in hydrogen-oxygen fuel cell is determined to be a low pressure power generation mode, the control device can activate a third device corresponding to the low pressure power generation mode. This allows the device corresponding to the driving mode to supply power to the motor. This allows the device with a built-in hydrogen-oxygen fuel cell to generate power underwater, on the surface of the water, in the air, or at high altitude, freeing the device from environmental constraints. Furthermore, embodiments of the present invention determine a driving mode suitable for the device based on the environment in which the device is located, execute the control method corresponding to the driving mode, and activate the corresponding device to supply power to the motor, thereby extending the driving time of the device with a built-in hydrogen-oxygen fuel cell.

[0054] In a specific embodiment of the present invention, the device with a built-in hydrogen-oxygen fuel cell may be a trans-medium device with a built-in hydrogen-oxygen fuel cell, which can operate in underwater, surface, air, or high-altitude environments.

[0055] It should be understood that: various sensors can be set on the device with a built-in hydrogen and oxygen fuel cell as needed, and when the device with a built-in hydrogen and oxygen fuel cell is started, the device on the device with a built-in hydrogen and oxygen fuel cell can be initialized so that the data of the device can operate normally, and then the target data on the device with a built-in hydrogen and oxygen fuel cell can be obtained.

[0057] When the control device acquires the mode instruction information, the control device determines the driving mode of the device having a built-in hydrogen and oxygen fuel cell based on the judgment of the mode instruction information.

[0058] In a specific embodiment of the present invention, when a device with a built-in hydrogen and oxygen fuel cell obtains mode instruction information, the device with a built-in hydrogen and oxygen fuel cell needs to determine the driving mode in the mode instruction information so that the device with a built-in hydrogen and oxygen fuel cell can switch the driving mode according to the mode instruction information.

[0059] In some embodiments of the present invention, the target data also includes environmental parameters; step S101 further includes:

[0098] In a specific embodiment of the present invention, a battery is a device that converts chemical energy into electrical energy during discharge and converts electrical energy into chemical energy during charging. The control device can monitor the flight status of the device with a built-in hydrogen and oxygen fuel cell, and can also calculate the power consumption required for the operation of the device with a built-in hydrogen and oxygen fuel cell. At the same time, the power supply of the hydrogen and oxygen fuel cell power generation device and / or the photovoltaic power generation device can be judged according to the driving mode of the device with a built-in hydrogen and oxygen fuel cell. If the power supply of the hydrogen and oxygen fuel cell power generation device and / or the photovoltaic power generation device is less than the operating requirement of the device with a built-in hydrogen and oxygen fuel cell, the control device can start the battery to supply power to the motor. If the remaining power supply of the hydrogen and oxygen fuel cell power generation device and / or the photovoltaic power generation device is greater than the operating requirement of the device with a built-in hydrogen and oxygen fuel cell, the battery can be started. The battery can absorb the remaining power supply generated by the hydrogen and oxygen fuel cell power generation device and / or the photovoltaic power generation device, so that the device with a built-in hydrogen and oxygen fuel cell can sail for a longer time with limited energy.

When the driving mode is a closed power generation mode, the air inlet and the air outlet are closed. When the driving mode is a normal pressure power generation mode or a low pressure power generation mode, the air inlet and the air outlet are opened, so that the device with a built-in hydrogen and oxygen fuel cell can avoid water in the closed power generation mode and can obtain air in the normal pressure power generation mode or the low pressure power generation mode.

[0101] A photovoltaic power generation device is a power generation device that uses the photovoltaic effect of photovoltaic cells to convert solar radiation energy into electrical energy.
