Embodiment 1
[0059] Such as figure 1 As shown, a protection method for improving the security of the physical layer of the unmanned aerial vehicle, the protection method includes the following steps:
[0060] S1. Unexpected state detection of the UAV: The unexpected state refers to that when the UAV is controlled by the remote control, it cannot perform information interaction with the remote control, resulting in the loss of control of the UAV; The rear console interacts with information, causing the UAV to lose control; or / and the inclination or / and speed of the UAV exceed the preset threshold; or / and the UAV itself sends out an alarm message.
[0061] S2. Control the jet nozzle to generate reverse impact force: the controller of the UAV controls the opening of the first solenoid valve, so that the jet nozzle generates reverse impact force.
[0062] S3. Inflate the buffer airbag: the controller of the UAV controls the opening of the second solenoid valve to inflate the buffer airbag. ...
Embodiment 2
[0067] The invention discloses a protection method for improving the safety of the physical layer of an unmanned aerial vehicle, comprising the following steps:
[0068] S1: UAV fuselage tilt detection, use the gyroscope module to monitor the inclination angle of the drone itself, and transmit the measured data to the controller;
[0069] S2: Adjust the inclination angle of the UAV fuselage. After the controller receives the data, it processes the received data. The nozzle is sprayed to adjust the inclination angle of the drone, so that the drone is in a relatively balanced state;
[0070] S3: UAV descent speed detection, use the gyroscope module to monitor the UAV's descent speed, and transmit the measured data to the controller;
[0071] S4: Drone descending speed control, when the descending speed of the drone is fast, the buffer wings are expanded, and the drone is subjected to air resistance to achieve the purpose of slowing down;
[0072] S5: Measure the height of the ...
Embodiment 3
[0076] Such as Figure 2-7 As shown, a protection system for improving the safety of the physical layer of the drone includes a drone 5; the drone 5 has a support frame 1 and a rotating wing; the support frame 1 includes legs 10, two adjacent A crossbeam 17 is connected between the legs 10; a buffer layer is provided at the bottom of the legs 10, and the buffer layer is made of elastic material; the buffer layer includes multiple layers: the first buffer layer, the second buffer layer Two buffer layers and a wear-resistant layer; the first buffer layer is a rubber layer, the second buffer layer is a polyurethane foam layer, and the wear-resistant layer is a melamine resin layer.
[0077] The polyurethane layer is arranged at the bottom of the rubber layer; the spraying of the melamine resin is the bottom of the polyurethane foam layer, thus the rubber layer, the polyurethane foam layer and the melamine resin layer are sequentially arranged from top to bottom.
[0078] There a...
