Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) equipment, and particularly to a control method for a UAV parachute, a UAV parachute, and a UAV. Background Art

[0002] With the continuous and in-depth application of UAVs in power inspection work, various advanced technologies and advanced equipment have emerged. In recent years, the intelligent UAV nest has become the "new favorite" in power inspection applications due to a series of functions such as automatic battery swapping, precise takeoff and landing, remote control, environmental perception, autonomous operation, and remote networking. To ensure the safety of remotely operating UAVs in the nest, it is necessary to install a parachute device on the UAVs configured in the nest. The UAVs configured in the nest can perform operations such as battery swapping and powering on through the original robotic arm, and how to synchronize the opening and closing of the added parachute with the UAV is a major problem currently faced. Summary of the Invention

[0003] The first object of the present invention is to propose a control method for a UAV parachute. Using this method to control the UAV parachute can achieve adaptive start-stop control of the UAV parachute, thereby ensuring that the insurance of the UAV parachute is always in the open state when the UAV is in a moving state.

[0004] The second object of the present invention is to propose a UAV parachute that can achieve adaptive start-stop control, thereby ensuring that the insurance of the UAV parachute is always in the open state when the UAV is in a moving state.

[0005] The third object of the present invention is to propose a UAV that can ensure that the insurance of the UAV parachute is always in the open state during the flight process, thereby ensuring the flight reliability of the UAV.

[0006] To achieve the above technical effects, the technical solution of the present invention is as follows:

[0007] The present invention discloses a control method for a UAV parachute, including: detecting the ambient light intensity of the environment where the UAV body is located; determining the state of the cabinet door of the nest storing the UAV body according to the ambient light intensity. When the cabinet door is open, the insurance of the UAV parachute is opened, and when the cabinet door is closed, the insurance of the UAV parachute is closed.

[0008] In some embodiments, determining the state of the cabinet door of the nest storing the UAV body according to the ambient light intensity includes: if the ambient light intensity is greater than a first preset light intensity and remains for a first preset time, it is determined that the cabinet door is in the open state.

[0009] In some embodiments, determining the state of the cabinet door of the nest for storing the drone body according to the ambient light intensity includes that if the ambient light intensity is less than a second preset light intensity and remains at the second preset time, it is determined that the cabinet door is in a closed state.

[0010] In some embodiments, after the safety of the drone parachute is opened, it further includes: detecting the working state of the drone body and adjusting the working state of the drone parachute according to the working state of the drone body.

[0011] In some specific embodiments, detecting the working state of the drone body and adjusting the working state of the drone parachute according to the working state of the drone body includes: if the drone body is in a moving state, the safety of the drone parachute remains open; if the drone body is in a stationary state and the duration of the stationary state exceeds a preset duration, the safety of the drone parachute is closed.

[0012] The present invention also discloses a drone parachute, which is installed on the drone body through a clamping structure, and a photosensitive sensor for detecting the ambient light intensity is provided on the top wall of the drone parachute.

[0013] In some embodiments, the clamping structure includes two spaced clamping modules, and the two clamping modules are respectively clamped on two opposite side walls of the drone body.

[0014] In some embodiments, the drone parachute is further provided with a motion sensing sensor for sensing the motion state of the drone body.

[0015] In some specific embodiments, there are multiple motion sensing sensors, and the multiple motion sensing sensors are spaced on multiple side walls of the drone parachute.

[0016] The present invention also discloses a drone body, including the aforementioned drone parachute and drone body.

[0017] The beneficial effects of the control method of the drone parachute of the present invention: Through the detection of the light intensity, this control method of the drone parachute can identify whether the cabinet door is open, realizing the function of adaptively adjusting the opening or closing of the safety of the drone parachute according to the opening state of the cabinet door, ensuring that the safety of the drone parachute is always in an open state after the drone body takes off, and ensuring that the drone parachute can play a protective role when the drone body fails.

[0018] Beneficial effects of the drone parachute of the present invention: Since a photosensitive sensor for detecting ambient light intensity is provided on the drone parachute, the photosensitive sensor can determine whether the cabinet door is opened by detecting the change in light intensity, realizing the function of adaptively adjusting the opening or closing of the insurance of the drone parachute according to the opening state of the cabinet door, ensuring that the insurance of the drone parachute is always in the open state after the drone body takes off, and ensuring that the drone parachute can play a protective role when the drone body fails.

[0019] Beneficial effects of the drone of the present invention: Due to the drone parachute described above, the drone can ensure that the insurance of the drone parachute is always in the open state during the flight process, thereby ensuring the flight reliability of the drone.

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Next, refer to Figure 1 - Figure 2 Describe the method for controlling the drone parachute in two embodiments of the present invention.

[0032] Embodiment 1:

[0033] As Figure 1 shown, the control method of the drone parachute in this embodiment includes:

[0034] S1: Detect the ambient light intensity of the environment where the drone body is located;

[0035] S2: Determine the state of the cabinet door of the nest storing the drone body according to the ambient light intensity; it can be understood that in the actual working process, first, the internal structure of the nest is used to start the drone body and then open the cabinet door. When the cabinet door is opened, the drone body can take off. In this embodiment, by detecting the light intensity, it is possible to identify whether the cabinet door is opened, so as to adaptively adjust the opening or closing of the insurance of the drone parachute according to the opening state of the cabinet door, which can ensure that the insurance of the drone parachute is always in the open state after the drone body takes off, and ensure that the drone parachute can play a protective role when the drone body fails.

[0036] S21: If the ambient light intensity is greater than the first preset light intensity and remains at the first preset time, it is determined that the cabinet door is in the open state, and the insurance of the drone parachute is opened. It can be understood that during the actual working process, ambient light may enter the cabinet body through the gap of the cabinet door, that is to say, there may be an initial light intensity value inside the cabinet door. In this embodiment, only when the ambient light intensity is greater than the first preset light intensity and remains at the first preset time will it be determined that the cabinet door is in the open state, which can better reduce the probability of misjudgment caused by the initial light intensity and avoid the phenomenon that the drone parachute opens when the cabinet door is closed.

[0037] S22: Determining the state of the cabinet door of the nacelle storing the drone body according to the ambient light intensity includes that if the ambient light intensity is less than the second preset light intensity and remains at the second preset time, it is determined that the cabinet door is in the closed state, and when the cabinet door is closed, the insurance of the drone parachute is closed. It can be understood that during the actual working process, if the preset light intensity values for determining the opening and closing of the cabinet door are the same, in the case of weak ambient light, due to the accuracy limitation of the photosensitive sensor 1, misjudgment is likely to occur. In this embodiment, only when the ambient light intensity is less than the second preset light intensity and remains at the second preset time will it be determined that the cabinet door is in the closed state. The second preset light intensity can be set much smaller than the first preset light intensity, so that the misjudgment probability can be better reduced.

[0038] Embodiment 2:

[0039] As Figure 2 shown, the control method of the drone parachute in this embodiment includes:

[0040] S1: Detect the ambient light intensity of the environment where the drone body is located;

[0041] S2: Determine the state of the cabinet door of the nacelle storing the drone body according to the ambient light intensity; specifically,

[0042] S21: If the ambient light intensity is greater than the first preset light intensity and remains at the first preset time, it is determined that the cabinet door is in the open state, and when the cabinet door is open, the insurance of the drone parachute is opened;

[0043] S211: Detect the working state of the drone body and adjust the working state of the drone parachute according to the working state of the drone body; It can be understood that after the insurance of the drone parachute is opened, due to some special reasons, the drone body may not take off, or the cabinet door may not be closed in time after the drone body lands back in the nacelle. At this time, if the insurance of the drone parachute remains in the open state, the phenomenon of the drone parachute being accidentally triggered will be increased.

[0044] In this embodiment, the working state of the drone parachute can also be adjusted according to the working state of the drone body. Specifically, if the drone body is in a moving state, the insurance of the drone parachute remains open; if the drone body is in a stationary state and the duration of the stationary state exceeds a preset duration, the insurance of the drone parachute is closed. This can avoid the phenomenon that the drone parachute cannot be stably closed when the cabinet door of the drone nest is opened but the drone does not take off, or when the drone lands but the cabinet door is not closed, thus avoiding the occurrence of accidental triggering of the drone.

[0045] S22: Determining the state of the cabinet door of the drone nest for storing the drone body according to the ambient light intensity includes that when the ambient light intensity is less than the second preset light intensity and remains for the second preset time, it is determined that the cabinet door is in the closed state. When the cabinet door is closed, the insurance of the drone parachute is closed.

[0046] The following refers to Figure 3 - Figure 4 Describe the specific structure of the drone parachute according to the embodiments of the present invention.

[0047] The present invention also discloses a drone parachute, as Figure 3 - Figure 4 shown, the drone parachute is installed on the drone body through a clamping structure, and a photosensitive sensor 1 for detecting the ambient light intensity is provided on the top wall of the drone parachute. It can be understood that in the actual working process, first, the drone body is activated through the internal structure of the drone nest and then the cabinet door is opened. When the cabinet door is opened, the drone can take off. The photosensitive sensor 1 for detecting the ambient light intensity is provided on the drone parachute of this embodiment. The photosensitive sensor 1 can determine whether the cabinet door is opened by detecting the change in light intensity. In this way, the opening or closing of the insurance of the drone parachute can be adaptively adjusted according to the opening state of the cabinet door, ensuring that the insurance of the drone parachute is always in the open state after the drone body takes off, and ensuring that the drone parachute can play a protective role when the drone body fails.

[0048] In some embodiments, the clamping structure includes two spaced clamping modules 2, and the two clamping modules 2 are respectively clamped on two opposite side walls of the drone body. It can be understood that using two clamping modules 2 respectively clamped on two opposite side walls of the drone body can better improve the connection stability between the drone parachute and the drone body, thereby ensuring that the drone parachute can better protect the drone body.

[0049] In some specific embodiments, such as Figure 4As shown in the figure, the snap - on module 2 includes a support base 21, a connecting belt 22, and a claw 23. The support base 21 is connected to the housing of the drone parachute. The two ends of the connecting belt 22 are respectively connected to the support base 21 and the claw 23, and the claw 23 is connected to the drone body by screws. Thus, the distance between the support base 21 and the claw 23 can be adjusted by adjusting the length of the connecting belt 22, thereby adjusting the positions of the drone parachute and the drone body, which is convenient for use.

[0050] In some embodiments, the drone parachute is also provided with a motion sensing sensor for sensing the motion state of the drone body. It can be understood that after the insurance of the drone parachute is opened, due to some special reasons, the drone parachute may not take off, or the cabinet door of the drone body does not close in time after the drone body lands back in the nest. At this time, if the drone parachute continues to be in the open state, the phenomenon of the drone parachute being accidentally triggered will be increased. The added motion sensing sensor in this embodiment can adjust the working state of the drone parachute according to the working state of the drone body. Specifically, if the drone body is in a moving state, the insurance of the drone parachute remains open; if the drone body is in a stationary state, the drone parachute is closed. In this way, it can be avoided that when the cabinet door of the nest is opened and the drone body does not take off, or when the drone body lands and the cabinet door is not closed, the drone parachute can also be stably closed, avoiding the occurrence of the phenomenon of accidental triggering of the drone.

[0051] In some specific embodiments, there are multiple motion sensing sensors, and the multiple motion sensing sensors are arranged at intervals on multiple side walls of the drone parachute. Thus, the motion state of the drone body can be accurately sensed, ensuring stable detection of the working state of the drone body.

[0052] The present invention also discloses a drone, including the aforementioned drone parachute and the drone body.

[0053] For the drone of the present invention, due to having the drone parachute described above, this drone can ensure that the insurance of the drone parachute is always in the open state during the flight process, thereby ensuring the flight reliability of the drone.

[0054] In the description of this specification, the descriptions referring to terms such as "some embodiments", "other embodiments", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above - mentioned terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0055] The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, based on the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
