DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Refer to the instruction manual Figure 1-4A drone landing platform comprises a drone landing platform body 1, wherein the drone landing platform body 1 is arranged in two groups, wherein one end of the drone landing platform body 1 of one group is provided with a first slide groove 2, and one end of the drone landing platform body 1 of the other group is fixedly connected with a first slider 3, and the first slider 3 is arranged in a sliding connection with the first slide groove 2, and one end of the drone landing platform body 1 is provided with a second slide groove 4, and the other drone landing platform body 1 is fixedly connected with a second slider 5, and the second slide groove 4 is arranged in a sliding connection with the second slider 5, and an external expansion plate 6 is arranged inside the drone landing platform body 1, and a first plug-in column 8 is fixedly connected to one side of the external expansion plate 6, and a first plug-in groove 7 is arranged on the side of the drone landing platform body 1, and the first plug-in groove 7 is connected to the first plug-in column 8. The column 8 is arranged in an inserted state, and the bottom end of the outer expansion plate 6 is fixedly connected with a second inserted column 10. A second inserted groove 9 is opened on the surface of the drone landing platform body 1, and the second inserted column 10 and the second inserted groove 9 are arranged in an inserted connection relationship; when the drone landing platform body 1 is in use, the second slider 5 can be slid out of the second slide groove 4 by sliding the second slider 5, and then the first slider 3 is aligned with the first slide groove 2, and then sliding installation is performed. At this time, the two groups of drone landing platform bodies 1 are in a spliced ​​state. At this time, the outer expansion plate 6 fixed in the second inserted groove 9 by the second inserted column 10 is taken out and spliced ​​and installed according to the plug-in relationship between the first inserted column 8 and the first inserted groove 7, so that the second inserted column 10 forms a landing platform.

[0033] Then, four groups of external expansion plates 6 are arranged inside the drone landing platform body 1. A drone landing groove is opened on the surface of the drone landing platform body 1. The four groups of external expansion plates 6 are inserted into the side of the drone landing platform body 1 and the shape formed by the drone landing groove is a circle with a radius of 25CM; so that the drone landing platform body 1 becomes a circular drone landing platform with a radius of 25CM after being unfolded; it can adapt to most mainstream DJI drone models.

[0034] Then, a lifting handle 16 is fixedly connected to one end of the drone landing platform body 1, and a rubber gasket is fitted on the outer wall of the lifting handle 16; this structure makes the lifting handle 16 more firmly gripped, ensuring the anti-slip effect when the equipment is lifted and moved.

[0035] Next, four groups of auxiliary grooves 11 are opened on the outer wall surface of the drone landing platform body 1, and a stabilizing support rod 12 is rotatably connected inside each group of auxiliary grooves 11; through this structure, the drone landing platform body 1 can support the drone landing platform body 1 after the stabilizing support rod 12 rotates inside the auxiliary groove 11, thereby adapting to scenes with complex terrain or many ground obstacles.

[0036] At this time, a bend groove 13 is opened at one end of the stabilizing support rod 12, and the bend groove 13 is arranged in a semi-arc shape, and an anti-slip pattern is opened on the surface of the bend groove 13; through this structure, the stabilizing support rod 12 can be more conveniently taken out from the auxiliary groove 11 for operation.

[0037] Refer to the instruction manual Figure 5 , the outside of the two sets of drone landing platform bodies 1 are both installed with tilt angle sensors 14, and the surface of one set of drone landing platform bodies 1 is installed with an indicator light 15; the working process of the tilt angle sensor 14 is as follows: first, the two sets of tilt angle sensors 14 collect the tilt angles of the X-axis and Y-axis of the left and right sides of the two sets of drone landing platform bodies 1 at a frequency of every 100 milliseconds, wherein the X-axis is the front-to-back direction, and the Y-axis is the left-to-right direction;

[0038] Then the collected tilt angle data is subjected to denoising and data smoothing by a sliding average filtering algorithm;

[0039] Then the processed data is used to calculate the average tilt angles of the X-axis and Y-axis respectively using the weighted average formula: Among them, X avg represents the average tilt angle of the platform in the front and rear directions, X 1 and X 2 are the front and rear tilt angles collected by the sensors on the left and right sides respectively; avg Indicates the average tilt angle of the platform in the left and right directions, Y 1 and Y 2 They are the left and right tilt angles collected by the sensors on the left and right sides respectively;

[0040] At this time, the average inclination angle of the X-axis and the Y-axis is used to calculate the comprehensive inclination angle of the platform through the vector synthesis formula: Among them, θ total is the comprehensive tilt angle;

[0041] Finally, the comprehensive tilt angle is used to determine the tilt state of the platform. The judgment criteria are based on the safety operation requirements in actual applications, where:

[0042] When θ total When the angle is less than or equal to 3 degrees, the platform is considered to be in a stable state. In this state, the platform is stable enough for the drone to land safely.

[0043] When θ total When the tilt is greater than 3 degrees and less than or equal to 6 degrees, the platform is considered to be in a slight tilt state. Although the tilt in this range will not immediately affect the landing of the drone, there is a potential risk and it is recommended to adjust it;

[0044] When θ totalWhen it is greater than 6 degrees, the platform is judged to be in a serious tilt state. At this time, the platform is not suitable for the safe landing of the drone, and the platform must be readjusted or placed; the system performs weighted average processing on the collected tilt angles in the front-to-back direction and the left-to-right direction, and calculates the average tilt in each direction. Subsequently, the system comprehensively judges the overall tilt of the platform based on the average tilt in the two directions. If the tilt angles in the front-to-back and left-to-right directions are close, the platform is judged to be relatively stable; if the tilt in one direction is too large, the system will record the data and make further judgments to ensure that the overall state of the platform is within the monitoring range.

[0045] It should be noted that the indicator light 15 is linked to the sensor determination system through the control circuit, based on different θ total Values ​​trigger different light colors:

[0046] When θ total When the temperature is less than or equal to 3 degrees, the judgment system triggers the green light through the control circuit to indicate that the platform is safe;

[0047] When θ total When the angle is greater than 3 degrees and less than or equal to 6 degrees, it is slightly tilted and adjustment is recommended to ensure the best conditions for drone landing;

[0048] When θ total When it is greater than 6 degrees, the control circuit triggers a red light to remind the user that the platform is seriously tilted and must adjust its position immediately; after the sensor completes the collection and processing of the tilt angle data, the system determines the tilt state of the platform based on the comprehensive tilt angle, and feeds back the judgment result to the indicator light system through the control circuit. Specifically, when the comprehensive tilt angle is less than or equal to 3 degrees, the system determines that the platform is in a stable state, activates the green indicator light through the control circuit, and reminds the user that the platform is stable and does not need to be adjusted; when the comprehensive tilt angle is greater than 3 degrees but less than or equal to 6 degrees, the system determines that the platform is in a slight tilt state, activates the yellow indicator light, and reminds the user that the platform needs to be fine-tuned to avoid potential risks; when the comprehensive tilt angle is greater than 6 degrees, the system determines that the platform is seriously tilted, activates the red indicator light, and reminds the user to immediately adjust the platform position or reposition the platform.

[0049] The indicator light system is linked to the sensor's judgment results in real time to ensure that users can get intuitive feedback on the platform status at the first time. The indicator light conveys the platform status to the user through different color changes, thereby simplifying the user's operation process, allowing the user to make corresponding operation decisions only through color feedback, and can judge the safety of the platform without additional tools or manual operation.
