[0019] In the present embodiment, a UAV garage device for realizing automatic conversion of power supply mode is provided, Figure 1 is a structural block diagram of a UAV garage device for realizing automatic conversion of power supply mode according to an embodiment of the present application, as Figure 1 shown, the device comprises a photovoltaic module 101, a commercial power module 102, a first uninterruptible power supply 103, a second uninterruptible power supply 104, a static transfer switch 105, and a load module 106;

[0020] The photovoltaic module 101 and the commercial power module 102 are used to provide electric energy;

[0023] The second output interface of the second uninterruptible power supply 104 is electrically connected with the input interface of the load module 106, and is configured to supply power to the target UAV warehouse.

[0024] Optionally, the first uninterruptible power supply 103 is configured to receive and store the power output by the photovoltaic module 101.

[0025] Specifically, the photovoltaic module is a module for generating power by using solar energy, and converts light energy into electric energy. The commercial power module is connected to the power grid and provides power. The first uninterruptible power supply and the second uninterruptible power supply are an uninterruptible power supply system containing an energy storage device, wherein the first uninterruptible power supply can store the power of the photovoltaic module and provide power when the commercial power is interrupted, the second uninterruptible power supply receives power from the first uninterruptible power supply or the commercial power module and stores the power to provide power for the load module. The static transfer switch is an intelligent switch that can switch between the first uninterruptible power supply and the commercial power module to ensure the continuity of power supply. The load module is a module for receiving and distributing power, including various electrical equipment in the UAV warehouse.

[0026] The input interface of the first uninterruptible power supply is electrically connected with the output interface of the photovoltaic module, i.e., the first uninterruptible power supply receives the power output by the photovoltaic module. The first output interface of the first uninterruptible power supply is electrically connected with the first input interface of the static transfer switch, i.e., the first uninterruptible power supply outputs power to the static transfer switch.

[0027] The second input interface of the static transfer switch is electrically connected with the output interface of the commercial power module 102, i.e., the static transfer switch receives the power output by the commercial power module. The output interface of the static transfer switch 105 is electrically connected with the input interface of the second uninterruptible power supply, i.e., the second uninterruptible power supply receives the power of the first uninterruptible power supply or the power of the commercial power module through the static transfer switch, wherein the static transfer module switches to select the first uninterruptible power supply or the commercial power module.

[0028] The second output interface of the second uninterruptible power supply is electrically connected with the input interface of the load module, i.e., the load module receives the power output by the second uninterruptible power supply, and supplies power to the target UAV warehouse.

[0029] In summary, through the combination of the photovoltaic module, the commercial power module, the first uninterruptible power supply, the static transfer switch, the second uninterruptible power supply and the load module, automatic switching of the power supply mode of the UAV warehouse is realized, and the power supply stability of the UAV warehouse is improved.

[0030] In an optional embodiment, the static transfer switch 105 is configured to switch between a first power supply state and a second power supply state; the first power supply state is that the first uninterruptible power supply 103 supplies power to the second uninterruptible power supply 104; the second power supply state is that the commercial power module supplies power to the second uninterruptible power supply 104.

[0031] Specifically, the static transfer switch is responsible for flexible switching between the two power supply states to ensure the stability and continuity of power supply. When in the first power supply state, the static transfer switch switches the circuit to the mode of the first uninterruptible power supply powering the second uninterruptible power supply, which usually occurs when the first uninterruptible power supply has sufficient stored energy. When switching to the second power supply state, the static transfer switch switches to the mode of the second uninterruptible power supply being directly powered by the mains module, which usually occurs when the first uninterruptible power supply has insufficient stored energy.

[0032] Optionally, when in the second power supply state, the first uninterruptible power supply receives and stores the energy output by the photovoltaic module, and the photovoltaic module charges the first uninterruptible power supply. The first uninterruptible power supply switches to the first power supply state after storing energy to the first preset threshold.

[0033] Optionally, the amount of electricity of the first uninterruptible power supply and the second uninterruptible power supply is monitored. When the amount of electricity of the first uninterruptible power supply and the second uninterruptible power supply is greater than a preset value, the static transfer switch switches to the first power supply state. When the amount of electricity of the first uninterruptible power supply is less than the preset value and the amount of electricity of the second uninterruptible power supply is greater than the preset value, the static transfer switch switches to the second power supply state. When the amount of electricity of the second uninterruptible power supply is less than the preset value, the static transfer switch switches to the second power supply state to avoid the drone warehouse being powered off, and switches to the first power supply state after the amount of electricity of the second uninterruptible power supply reaches the second preset threshold.

[0034] For example, when the amount of electricity of the first uninterruptible power supply and the second uninterruptible power supply is greater than 10%, the static transfer switch switches to the photovoltaic (first uninterruptible power supply) to charge the second uninterruptible power supply. When the amount of electricity of the first uninterruptible power supply is less than 10% and the amount of electricity of the second uninterruptible power supply is greater than 10%, the static transfer switch switches to the mains to charge the second uninterruptible power supply, and the photovoltaic charges the first uninterruptible power supply, and the first uninterruptible power supply stores energy from the photovoltaic. When the amount of electricity of the first uninterruptible power supply reaches 100% full charge, the static transfer switch switches to the photovoltaic (first uninterruptible power supply) to charge the second uninterruptible power supply. When the amount of electricity of the second uninterruptible power supply is less than 10%, the static transfer switch switches to the mains to charge the second uninterruptible power supply to avoid the drone warehouse being powered off. When the amount of electricity of the second uninterruptible power supply is 100%, the static transfer switch switches to the first uninterruptible power supply for power supply.

[0035] The embodiment can automatically select the most suitable power supply mode according to different power supply conditions and requirements, thereby ensuring the reliability and efficiency of power supply in the drone warehouse.

[0036] In an optional embodiment, as Figure 2As shown, the device further comprises an MCU controller 107, a second input interface of the MCU controller 107 is communicatively connected with a first output interface of the second UPS 104; a second output interface of the first UPS 103 is communicatively connected with a first input interface of the MCU controller 107; and a control interface of the static transfer switch 105 is communicatively connected with an output interface of the MCU controller 107.

[0037] Specifically, the MCU controller is an integrated circuit integrating a central processing unit (CPU), a memory, an input / output interface and the like, and is capable of monitoring and managing the operation of other components. The MCU controller is communicatively connected with the first output interface of the second UPS through the second input interface thereof, so as to be capable of acquiring the power state information of the UPS 2 in real time. Meanwhile, the second output interface of the first UPS is communicatively connected with the first input interface of the MCU controller, so as to ensure that the MCU controller is capable of acquiring the power state information of the first UPS. The control interface of the static transfer switch is communicatively connected with the output interface of the MCU controller, and the MCU sends a control signal to the static transfer switch according to the current power strategy and the power state information of the first UPS and the second UPS, so as to realize the switching between the first power supply state and the second power supply state.

[0038] The embodiment not only improves the stability and reliability of the unmanned aerial vehicle warehouse power supply system, but also realizes the efficient use of electric energy.

[0039] In an alternative embodiment, the first UPS 103 is further configured to output a first power signal through a second output interface of the first UPS 103; and the second UPS 104 is further configured to output a second power signal through a second output interface of the second UPS 104.

[0040] Specifically, the first power signal comprises the power state information of the first UPS. The second power signal comprises the power state information of the second UPS. The first power signal and the second power signal are the basis for the MCU controller to send a control signal. The first UPS not only stores and provides electric energy, but also outputs a first power signal through the second output interface thereof. Similarly, the second UPS outputs a second power signal through the second output interface thereof. The first power signal and the second power signal are sent to the MCU controller, so that the MCU controller is capable of grasping the power state information of the two UPSs in real time and accurately.

[0041] In the embodiment of the utility model, Figure 3 As shown, the first UPS 103 sends a first power signal to the MCU controller 107, the second UPS 104 sends a second power signal to the MCU controller 107, and the MCU controller 107 sends a control signal to the static transfer switch 105.

[0042] The embodiment makes the control unit make a reasonable decision based on the first electric quantity signal and the second electric quantity signal, thereby improving the stability and reliability of the power supply of the unmanned vehicle warehouse.

[0043] In an alternative embodiment, when the static transfer switch 105 receives the switching signal sent by the MCU controller 107, the first uninterruptible power supply 103 and the second uninterruptible power supply 104 are controlled to be electrically connected, or the utility power module and the second uninterruptible power supply 104 are controlled to be electrically connected.

[0044] Specifically, when the MCU controller of the unmanned vehicle warehouse power supply system determines that power switching is needed according to the current acquired electric quantity signal (the first electric quantity signal from the first uninterruptible power supply and the electric quantity signal from the second uninterruptible power supply), it sends a control signal to the static transfer switch. After the static transfer switch receives the control signal, the static transfer switch is controlled. The first uninterruptible power supply and the second uninterruptible power supply are controlled to establish an electrical connection between them, or the utility power module and the second uninterruptible power supply 104 are controlled to establish an electrical connection between them. When the first uninterruptible power supply and the second uninterruptible power supply are electrically connected, they are in the first power supply state. When the utility power module and the second uninterruptible power supply 104 are electrically connected, they are in the second power supply state.

[0045] Optionally, the control signal refers to the control instruction selectively sent by the MCU controller to the static transfer switch according to the electric quantity signal, the power supply demand or other preset conditions

[0046] Specifically, the control signal includes:

[0047] Switching signal: when the MCU controller detects that the electric quantity of the first uninterruptible power supply is sufficient, and the second uninterruptible power supply needs to be charged or has low electric quantity, it sends a switching signal to the static transfer switch, instructing it to electrically connect the first uninterruptible power supply and the second uninterruptible power supply, so as to charge the second uninterruptible power supply.

[0048] Utility access signal: when the MCU controller detects that the electric energy generated by the photovoltaic module is insufficient to meet the power demand of the unmanned vehicle warehouse, and the electric quantity of the first uninterruptible power supply is also close to depletion, it sends a utility access signal to the static transfer switch, instructing it to electrically connect the utility power module and the second uninterruptible power supply, so as to introduce utility power supply.

[0049] Maintain status signal: if the MCU controller determines that the current power supply state is good and does not need any switching operation, it sends a maintain status signal to the static transfer switch, instructing it to keep the current power connection state unchanged.

[0050] The embodiment ensures that the unmanned vehicle garage can obtain stable and reliable power supply, and improves power supply stability and reliability.
