[0045] like Figure 1 As shown, in at least one disclosed embodiment, a smart lifebuoy power supply system is provided, comprising: a control module, and a power supply module electrically connected to the control module; the power supply module is electrically connected to a low discharge rate battery module and a high discharge rate battery module, and the low discharge rate battery module and the high discharge rate battery module are both suitable for supplying power to a load; the control module is configured to control the power supply module to adjust the charging parameters of the high discharge rate battery module so as to stably charge the high discharge rate battery module; stable charging of the high discharge rate battery module is achieved, and the service life of the high discharge rate battery module is avoided from being affected by fluctuations in the charging voltage, and the power supply performance of the high discharge rate battery module is also avoided from being affected.

[0046] The low discharge rate battery module is an ordinary battery, and the high discharge rate battery module is a high charge and discharge rate battery, such as a 5C (Capacity) battery.

[0047] like Figure 2As shown, in an optional embodiment, the control module is configured to control the power module to adjust the charging parameters of the high discharge rate battery module, that is, the control module provides a preset voltage to the high discharge rate battery module through the power module, and the power module detects the charging voltage of the high discharge rate battery module in real time, and the control module adjusts the charging strategy for the high discharge rate battery module according to the charging voltage of the high discharge rate battery module; according to the charging voltage detected in real time, the power module is adjusted so that the charging voltage is always maintained at the preset voltage, so that the high discharge rate battery module can be stably charged.

[0048] In an optional embodiment, the control module adjusts the charging strategy for the high discharge rate battery module according to the charging voltage of the high discharge rate battery module, that is, if the charging voltage is greater than the preset voltage, the control module controls the power module to transmit the portion of the charging voltage higher than the preset voltage to the low discharge rate battery module, so that the charging voltage drops to the preset voltage; if the charging voltage is less than the preset voltage, the control module controls the power module to transmit the voltage in the low discharge rate battery module to the high discharge rate battery module, so that the charging voltage is increased to the preset voltage; a specific embodiment may be that the stable charging voltage of the high discharge rate battery module is 5V, which is detected in real time by the power module. If the charging voltage of the high discharge rate battery module is higher than 5V, for example, it reaches 5.1V, the power module transmits a voltage of 0.1V with a fluctuation higher than 5V to the low discharge rate battery module for charging. , stabilize the charging voltage of the high discharge rate battery module at 5V. If the charging voltage of the high discharge rate battery module is higher than or lower than 5V, for example, 4.9V, the power module provides a voltage of 0.1V through the low discharge rate battery module to charge the high discharge rate battery module, so that the charging voltage of the high discharge rate battery module is maintained at 5V; when the charging voltage is higher than the preset voltage, the low discharge rate battery module is charged with the excess voltage, and the low discharge rate battery module can be used to supply power when the low discharge rate battery module is needed to supplement the charging voltage; the fluctuation of the charging voltage of the high discharge rate battery module will not last for a long time and will not fluctuate frequently. Even if the power in the low discharge rate battery module is not enough to supply the drive motor, the power in the low discharge rate battery module can also supply power to the high discharge rate battery module to maintain the charging voltage of the high discharge rate battery module at the preset voltage.

[0049] like Figure 3As shown, in an optional embodiment, the control module is electrically connected to a temperature module, and the temperature module is suitable for detecting the temperature of the high discharge rate battery module; the control module is configured to adjust the charging current of the high discharge rate battery module according to the temperature of the high discharge rate battery module; if the temperature of the high discharge rate battery module is too high, it will affect its charging efficiency and service life, and if the high discharge rate battery module maintains the original charging speed under high temperature conditions, it will cause the temperature of the high discharge rate battery module to be too high, resulting in damage to the high discharge rate battery module, so it is necessary to adjust the charging speed when the high discharge rate battery module is in operation.

[0050] In an optional embodiment, the control module is configured to adjust the charging current of the high discharge rate battery module according to the temperature of the high discharge rate battery module, that is, the power module is suitable for detecting the charging current of the high discharge rate battery module in real time; the control module is configured to adjust the charging current of the high discharge rate battery module according to the temperature; the higher the temperature of the high discharge rate battery module, the smaller its charging current, so as to reduce the charging speed of the high discharge rate battery module, avoid the temperature of the high discharge rate battery module from continuing to increase, and avoid the temperature of the high discharge rate battery module from exceeding the maximum preset temperature.

[0051] In an optional embodiment, the control module is configured to adjust the charging current of the high discharge rate battery module according to the temperature, that is, if the temperature is higher than the maximum preset temperature, the control module controls the power module to stop charging the high discharge rate battery module; if the temperature is lower than the maximum preset temperature and higher than the first preset temperature, the control module controls the power module to adjust the charging current of the high discharge rate battery module. Between the maximum preset temperature and the first preset temperature, the higher the temperature, the lower the charging current; if the temperature is lower than the first preset temperature, the control module controls the power module to charge the high discharge rate battery module with the highest charging current; a specific embodiment may be that the maximum preset temperature for charging the high discharge rate battery module may be 70 degrees Celsius, the first preset temperature may be 40 degrees Celsius, and the current corresponding to the fastest charging speed of the high discharge rate battery module is 10A. When the temperature exceeds 70 degrees Celsius, the control module It is determined that the temperature of the high discharge rate battery module is too high. At this time, the power module directly stops charging the high discharge rate battery module, and the power module starts charging the low discharge rate battery module, waiting for the temperature of the high discharge rate battery module to drop. At this time, after the temperature of the high discharge rate battery module drops below 40 degrees Celsius, the power module restarts charging the high discharge rate battery module, and the charging current is 10A at this time; if the temperature of the high discharge rate battery module is lower than 40 degrees Celsius, the power module charges the high discharge rate battery module with a charging current of 10A; when the temperature of the high discharge rate battery module rises to more than 40 degrees Celsius, the power module gradually reduces the charging current as the temperature of the high discharge rate battery module rises, and reduces the charging speed to avoid the high discharge rate battery module from being too high. For example, when the temperature rises to nearly 70 degrees Celsius, the charging current of the high discharge rate battery module drops to a minimum of 1A.

At this time, the drive motor is powered by the high discharge rate battery module, so that the smart life buoy can approach the person who falls into the water as soon as possible. After the smart life buoy approaches the person who falls into the water to a preset distance, the propeller speed is reduced through the low discharge rate battery module, so that the smart life buoy approaches the person who falls into the water more slowly, so as to avoid the smart life buoy moving too fast and causing the person who falls into the water to be unable to contact and grab the smart life buoy. After the person who falls into the water grabs the smart life buoy, the drive motor is powered by the high discharge rate battery module and the low discharge rate battery module at the same time, so as to keep the propeller rotating at a high speed after the smart life buoy rescues the person who falls into the water, so as to rescue the person who falls into the water.
