[0002] In the existing conventional integrated shooting device, a non-modular integrated design is usually adopted, and only a single power supply system is provided. Such a design can meet the basic functional requirements, but its inherent architecture has significant limitations. Since the components (such as the gimbal and the camera) are in a fixed integrated relationship with the main device, flexible disassembly and independent replacement cannot be achieved. With the diversification of application scenarios and the upgrading of user needs, innovative solutions that support the detachable gimbal camera have emerged. However, this solution needs to interface with two independent systems, namely the unmanned aerial vehicle platform and the handheld control handle, resulting in a significant increase in power management complexity.

[0003] In this process, compatibility issues across systems must be addressed, including but not limited to power parameter detection, voltage / current adaptation adjustment, overload protection, short circuit protection, and thermal management, among other key technical challenges. The existing technology has not yet formed an efficient, safe, and stable solution for such multi-system collaborative work. SUMMARY

[0013] Optionally, determining the host type of the corresponding connection object of the gimbal camera comprises:

[0014] After detecting the interface electrical connection of the gimbal camera, if the negotiation signal of the universal serial bus charging protocol is detected, it is determined that the host type of the corresponding connection object of the gimbal camera is the handheld handle.

[0015] Optionally, if the unmanned aerial vehicle and the handheld handle are simultaneously kept in electrical connection with the gimbal camera, the method further comprises:

[0018] If the percentage of the remaining power is not greater than the set threshold, the second load switch is connected, the power supply mode of the handheld handle is set to supply power to the gimbal camera, and the first load switch is disconnected.

[0019] Optionally, the method further comprises:

[0020] If the interface electrical connection is detected to be disconnected when the gimbal camera is in the power supply state, the load switch of the first power supply end is disconnected, and the capacitor group arranged inside the gimbal camera is enabled;

[0039] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0040] Reference Figure 1 , Figure 1 A flow chart of a power supply control method of a gimbal camera provided by an embodiment of the present application, the method comprising:

[0041] S101: When detecting that an interface of the gimbal camera is electrically connected, determining a host type of a connection object corresponding to the gimbal camera;

[0042] S102: If the host type is a UAV, supplying power to the gimbal camera after the DC voltage of the UAV is stepped down;

[0043] S103: If the host type is a handheld handle, supplying power to the gimbal camera after setting a power supply mode of the handheld handle.

[0044] It is easy to understand that the steps S102 and S103 in the embodiment of the application have no established execution sequence relationship, the step sequence number marked in the embodiment is only used to indicate the execution sequence of the step S101 and the subsequent two steps. The steps S102 and S103 are actually selective steps based on the determination result of the host type, and both have the same execution priority.

[0045] The gimbal camera described in the application can be detachably connected with the unmanned aerial vehicle and the handheld handle respectively, and the embodiment does not limit the specific connection mode.

[0046] In step S101, it is necessary to determine the host type of the connection object, which includes the unmanned aerial vehicle and the handheld handle, both of which can supply power to the gimbal camera. In this regard, how to determine the host type of the connection object is not specifically limited. In a feasible implementation manner, an interface identification signal during interface electrical connection can be acquired, and the host type of the connection object corresponding to the gimbal camera is determined according to the interface identification signal.

[0047] Specifically, after ensuring that the interface of the gimbal camera and the connection object (such as the host) has been correctly connected, the electrical contacts inside the interface will come into contact with each other during the connection process, thereby forming an electrical connection. At this time, there is usually a signal line or circuit inside the interface for identification. Through the design of the circuit inside the interface, the interface identification signal is detected. This signal can be represented by a specific voltage level, current change or data communication protocol. For example, some interfaces may send a fixed voltage signal when connected, or send a specific identification code through serial communication.

[0048] The detected interface identification signal is compared with the preset host type identification standard. The host type identification standard can be pre-stored in the control system of the gimbal camera according to different host types. For example, if the interface identification signal is a specific voltage value, the system will match this voltage value with the voltage values corresponding to each host type stored in the system.

[0049] The host type of the connection object is determined according to the comparison result. If the detected signal is consistent with the preset signal of a certain host type, it can be confirmed that the gimbal camera is connected to the host of this type. If the signals do not match, the system can prompt the user to check whether the connection is correct, or try to reconnect.

[0050] In another feasible implementation manner, the power supply ripple characteristics after interface electrical connection can also be acquired, and the host type of the connection object corresponding to the gimbal camera is determined according to the ripple frequency of the power supply ripple characteristics. Usually, the first ripple frequency of the unmanned aerial vehicle is greater than the second ripple frequency of the handheld handle.

[0051] After the gimbal camera and the connection object (such as a drone or a handheld handle) are electrically connected, the power supply ripple characteristics can be obtained, and the host type of the connection object can be determined according to the ripple frequency:

[0052] Ensure that the interface of the gimbal camera and the connection object has been correctly connected, and the power supply circuit has been established. At this time, the power input end of the gimbal camera will receive the power supply voltage from the connection object.

[0053] A high-precision oscilloscope or ripple detection device can be connected to the power input end of the gimbal camera. The oscilloscope can display the waveform of the power supply voltage in real time, including the direct current voltage and the ripple signal superimposed on it. Connect the probe of the oscilloscope to the power supply interface of the gimbal camera, and ensure that the ground end of the probe is connected to the ground of the power supply to obtain accurate measurement results.

[0054] Observe the power supply voltage waveform displayed on the oscilloscope. The ripple is usually represented as a high-frequency alternating current signal superimposed on the direct current voltage. By adjusting the time and voltage scales of the oscilloscope, the amplitude and frequency of the ripple can be clearly seen. In the measurement function of the oscilloscope, select the "frequency" measurement option to obtain the frequency value of the ripple signal.

[0055] After obtaining the ripple frequency, compare it with the pre-set standard. According to the topic description, the first ripple frequency of the drone is greater than the second ripple frequency of the handheld handle. Therefore, if the measured ripple frequency is high, it can be judged that the connection object is a drone; if the ripple frequency is low, it can be judged that the connection object is a handheld handle.

[0056] Store the comparison result in the control system of the gimbal camera, so that subsequent operations can be adjusted or prompted according to the type of the connection object. For example, if the connection object is detected as a drone, the system can automatically switch to a control mode suitable for drones; if it is a handheld handle, switch to a handheld mode.

[0057] Power supply ripple refers to the alternating current component superimposed on the output of a direct current power supply. The ideal output of a direct current power supply should be a smooth direct current voltage, but in actual application, due to the imperfections of the power supply circuit and other factors, there will be some alternating current fluctuations, i.e. ripple. The first ripple frequency of the drone is usually greater than 1 kHz. Hertz (Hz) is the unit of frequency, representing the number of periodic changes per second. When the ripple frequency is higher than 1 kHz, it belongs to high-frequency ripple.

[0058] In other possible implementation manners, after detecting that the interface of the gimbal camera is electrically connected, if the USB charging protocol negotiation signal is detected, it is determined that the host type of the connection object corresponding to the gimbal camera is a handheld handle.

[0059] The negotiation signal of the USB-C PD protocol refers to the signal generated during the communication and negotiation process between devices using USB-C interfaces, such as handheld controllers, through the USB Power Delivery (PD) protocol. Digital handshake is a communication mechanism used to establish a connection between two devices and confirm each other's identity and capabilities. In the USB-C PD protocol, the handshake process is completed by sending and receiving specific messages.

[0060] The USB Power Delivery (PD) protocol is a charging protocol used to transmit higher power through USB interfaces, used to negotiate power management, data transmission, and role allocation between devices with USB-C interfaces. The negotiation process of the negotiation signal of the USB-C PD protocol includes the following steps:

[0061] Step 1, physical connection detection: detect whether the handheld controller and the gimbal camera are effectively connected through the CC pin.

[0062] Step 2, initialize power supply: provide a default 5V voltage.

[0063] Step 3, establish communication channel: send SOP (Start of Packet) signal through CC pin.

[0064] Step 4, negotiate power supply parameters: negotiate the required voltage and current between the handheld controller and the gimbal camera through message exchange.

[0065] Step 5, confirm power supply status: after successful negotiation, the controller starts supplying power according to the negotiated parameters.

[0066] For devices such as handheld controllers, the PD protocol negotiation can also include some specific functions, such as the handheld controller may require a specific voltage and current to support its operation, and can also transmit control signals or status information through the PD protocol.

[0067] The embodiments of the present application detect the interface electrical connection and determine the host type of the connected object. The gimbal camera can automatically identify whether the connected device is a drone or a handheld handle, and take appropriate power supply strategies according to different host types, avoiding the user's manual setting of power parameters, and improving the ease of use of the gimbal camera charging process. At the same time, for the drone, the step-down power supply mode is adopted to ensure that the gimbal camera can work normally under the higher DC voltage provided by the drone, and to avoid damage to the camera due to excessive voltage. For the handheld handle, by setting a specific power supply mode, the gimbal camera can stably operate under the power supply conditions of the handheld device, accurately adapt to different power supply conditions, and improve the compatibility and reliability of the gimbal camera. In addition, the gimbal camera can seamlessly switch and adapt to two different connection objects (drone and handheld handle), without the need for additional adapters or power conversion devices, not only reducing the user's use cost, but also improving the versatility and flexibility of the gimbal camera in different application scenarios.

[0068] Referring to Figure 2 , Figure 2 A power supply control process diagram of a gimbal camera provided by the embodiments of the present application corresponds to the power supply control method of the gimbal camera described in the above embodiments, Figure 2 includes:

[0069] The detection module is used to determine the host type of the connected object corresponding to the gimbal camera.

[0070] Drone: If the detected host type is a drone, it will enter the "drone" branch. The drone usually provides a full-power mode power supply of 12V / 2A.

[0071] MOSFET switch circuit: In the drone branch, a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) switch circuit is used to control the on-off of the power supply. MOSFET is a commonly used electronic switch used to control the flow of current.

[0072] Handheld handle: If the detected host type is a handle, it will enter the "handle" branch. The handle can provide a power-saving mode power supply of 5V.

[0073] USB-PD protocol chip: In the handle branch, a USB-PD (USB Power Delivery) protocol chip is used to control the power supply.

[0074] Gimbal motor drive: Both the drone branch and the handle branch will eventually be connected to the gimbal motor drive, which is the core component of the gimbal camera, responsible for driving the motor to realize the rotation of the gimbal.

[0075] The gimbal motor drive is provided with power-off protection for protecting the gimbal camera and related circuits when the power supply fails to prevent damage.

[0076] On the basis of the above embodiments, the following further describes possible charging scenarios.

[0077] If the unmanned aerial vehicle and the handheld handle are simultaneously kept in electrical connection with the gimbal camera, the remaining percentage of the power of the unmanned aerial vehicle can be detected at this time;

[0078] If the remaining percentage of the power is greater than a set threshold, the direct current voltage of the unmanned aerial vehicle is stepped down, the first load switch is connected, the gimbal camera is powered, and the second load switch of the handheld handle is disconnected, and the power supply mode of the handheld handle is set to the suspended power supply mode;

[0079] If the remaining percentage of the power is not greater than the set threshold, the second load switch is connected, the power supply mode of the handheld handle is set, the gimbal camera is powered, and the first load switch is disconnected.

[0080] When the unmanned aerial vehicle and the handheld handle are simultaneously kept in electrical connection with the gimbal camera, the remaining percentage of the power of the unmanned aerial vehicle is first detected. If the remaining percentage of the power is greater than a set threshold, the direct current voltage of the unmanned aerial vehicle is stepped down, the first load switch is connected, the gimbal camera is powered, and the second load switch of the handheld handle is disconnected, and the power supply mode of the handheld handle is set to the suspended power supply mode. Conversely, if the remaining percentage of the power of the unmanned aerial vehicle is not greater than the set threshold, the second load switch of the handheld handle is connected, the power supply mode of the handheld handle is set, the gimbal camera is powered, and the first load switch of the unmanned aerial vehicle is disconnected.

[0081] The unmanned aerial vehicle has stronger power supply capability and is a key device for high-altitude operation, so the power supply of the unmanned aerial vehicle is preferentially guaranteed. Only when the power of the unmanned aerial vehicle is sufficient, that is, the remaining percentage of the power is greater than a set threshold, the unmanned aerial vehicle is enabled to power the gimbal camera. Specifically, the INA219 power meter chip can be used to collect the voltage of the battery of the unmanned aerial vehicle in real time. If the remaining percentage of the power of the unmanned aerial vehicle is less than or equal to the set threshold, only the unmanned aerial vehicle is powered, and the power supply circuit of the handle is disconnected. If the remaining percentage of the power of the unmanned aerial vehicle is less than or equal to the set threshold, the handle auxiliary power supply is disconnected. In addition, in order to reduce the power consumption of the unmanned aerial vehicle, the handle auxiliary power supply can also be enabled to form a parallel power supply system to power the gimbal camera.

[0082] Referring to Figure 3 , Figure 3 The power supply control logic diagram of the gimbal camera provided by the embodiments of the present application is given, and the unmanned aerial vehicle power supply scheme and the handheld handle power supply scheme are given, and specifically include:

[0083] Referring to Figure 3 (a) the corresponding unmanned aerial vehicle power supply scheme:

[0084] The battery of the drone provides a voltage of 24V. The voltage is reduced from 24V to 12V by a DC-DC converter to adapt to the voltage requirement of the gimbal camera. A load switch of SI3655DV model is used to control the on-off of the power supply. The first load switch is activated by an enable signal to power the gimbal camera.

[0085] Referring to Figure 3 (b) Corresponding handle power supply scheme:

[0086] The battery of the handle provides a voltage of 7.4V. An FP6601Q chip is used to manage the power supply. A power supply of 5V is output through the USB Power Delivery (PD) protocol. A load switch of TPS22965 model is used to control the on-off of the power supply. The second load switch is activated by an enable signal to power the gimbal camera.

[0087] In actual application, a dual-channel MOSFET load switch can be used, Q1 (N-channel) of the dual-channel MOSFET load switch controls the power supply path of the drone, and Q2 (P-channel) of the dual-channel MOSFET load switch controls the power supply path of the handle. At this time, the gimbal camera can control the gate voltage through the GPIO to realize millisecond-level switching of the power supply end.

[0088] On the basis of the above-mentioned embodiments, as a preferred embodiment, if the interface electrical connection is detected to be disconnected when the gimbal camera is in a power supply state, the load switch of the first power supply end is disconnected, and the capacitor group arranged in the gimbal camera is enabled. Within the storage period of the capacitor group, the chip attitude parameters of the gimbal camera are maintained.

[0089] When the gimbal camera is in a power supply state, if the interface electrical connection is detected to be disconnected, the system will disconnect the load switch of the first power supply end and enable the capacitor group arranged in the gimbal camera.

[0090] The role of the internal capacitor group is to provide temporary power support when the power supply is interrupted to maintain the key parameters (such as chip attitude parameters) of the gimbal camera. The capacity of the capacitor group is not specifically limited and can be set by those skilled in the art according to the power consumption and retention time requirements of the gimbal camera. For example, if the power consumption of the gimbal camera is 1W and the required retention time is 5 seconds, the capacity of the capacitor group needs to meet the requirements of the power consumption and time.

[0091] Within the storage period of the capacitor group, the system maintains the chip attitude parameters of the gimbal camera to ensure that the device can quickly recover to the working state when the power supply is reconnected.

[0092] After the internal capacitor group is enabled, the system identifies the host type of the second power supply end connected to the gimbal camera. According to the identification result, the power supply strategy suitable for the host type of the second power supply end is called to power the gimbal camera.

[0093] For example, if the second power supply end is a handheld handle, the system enters a handheld handle power supply mode; if the second power supply end is a drone, the system enters a drone power supply mode.

[0094] It can be seen that the embodiment can quickly restore the power supply of the gimbal camera, and reduce the risk of equipment failure caused by power interruption.

[0095] In addition, the process can also realize the hot plug of the power supply end. The following is an exemplary hot plug switching timing:

[0096] Time point 0ms: physical connection is disconnected;

[0097] Time point 1ms: main power supply is cut off;

[0098] Time point 5ms: super capacitor is activated;

[0099] Time point 15ms: new host identification is completed;

[0100] Time point 20ms: new power supply is established;

[0101] Time point 25ms: the gimbal resumes work.

[0102] Referring to Figure 4 , Figure 4 A power supply control system structure diagram of a gimbal camera provided by the embodiment of the application, the system comprises:

[0105] A handle power supply module, configured to supply power to the gimbal camera by setting the power supply mode of the handheld handle if the host type is a handheld handle.

[0106] Based on the above embodiment, as a preferred embodiment, the host type detection module comprises:

[0107] A first type detection unit, configured to acquire an interface identification signal when the interface is electrically connected, and determine the host type of the connected object corresponding to the gimbal camera according to the interface identification signal.

[0111] The third type detection unit is configured to, after detecting that the interface of the gimbal camera is electrically connected, if a negotiation signal of a universal serial bus charging protocol is detected, determine that the host type of the corresponding connection object of the gimbal camera is the handheld handle.

[0113] The power detection module is configured to detect a remaining power percentage of the unmanned aerial vehicle; if the remaining power percentage is greater than a set threshold, after the direct current voltage of the unmanned aerial vehicle is stepped down, the first load switch is connected, the second load switch of the handheld handle is disconnected, and the power supply mode of the handheld handle is set to the pause power supply mode; if the remaining power percentage is not greater than the set threshold, the second load switch is connected, the power supply mode of the handheld handle is set, the handheld handle is powered to the gimbal camera, and the first load switch is disconnected.
