Problems solved by technology
[0003] In the prior art, when an emergency occurs to the UAV, the high-speed rotating blades will pose a huge hidden danger to ground personnel and facilities after the UAV is out of control; If the blade has not stopped rotating, the oar rope will be entangled, the blade will cut the oar rope, etc.; the success rate of parachute opening of the parachute system cannot be guaranteed
In the traditional method, the flight control of the UAV directly controls the motor speed, but there is no synchronous correlation between the emergency parachute opening and the motor speed, and the parachute opening system depends on the flight control stability of the UAV, but In the case of emergency parachute opening, the flight control of the drone will also lose stability and fail to open the parachute

The invention discloses an unmanned aerial vehicle emergency control system, which comprises an unmanned aerial vehicle power system, a power supply module and an unmanned aerial vehicle state monitoring module. The UAV power system includes motors and propellers. The UAV status monitoring module is used to monitor the running status of the aircraft in real time. The system control unit is used to adjust the operating attitude and flight requirements of the UAV. Parachute module. A power supply control unit is connected between the power system of the drone and the power module, and the power control unit is used to cut off the signal of the power supply of the power system of the drone when the drone is in an emergency state. And the power supply self-locking unit, which is used to monitor the power supply control unit to realize the power supply self-locking of the UAV power system. The invention realizes the control shut-off and self-locking of the power system through the software logic and the hardware circuit, avoids the parachute from entanglement, and ensures the parachute opening success rate of the parachute system.
Description
technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to power control and protection of a power system of an unmanned aerial vehicle. Background technique [0002] Safety is the first consideration in the UAV flight process. Most UAVs at this stage are equipped with parachutes to enhance the safety of the system. [0003] In the prior art, when an emergency occurs in the UAV, the high-speed rotating blades have huge hidden dangers to ground personnel and facilities after the UAV is out of control; and when the parachute is opened in an emergency, the high-speed rotating blades The blade has not stopped rotating, the paddle rope will be tangled, the blade will cut the paddle rope, etc.; the success rate of parachute opening of the parachute system cannot be guaranteed. The traditional method generally controls the motor speed directly by the UAV's flight control, but there is no synchronization correlation between the emergency...
