The invention discloses a civil unmanned aerial vehicle safety emergency slow descent intelligent parachute preparation method. The method is realized through the following steps that a main control box judges the current flight attitude and an acceleration state of an unmanned aerial vehicle through an attitude sensor and an accelerometer, when the attitude/acceleration of the unmanned aerial vehicle reaches a trigger judgment condition or a PWM trigger signal is received, an electronic igniter ignites a propellant, the propellant burns and pops a parachute bag out of a parachute cabin, the parachute is subjected to air resistance in the descending process, the descending speed of the unmanned aerial vehicle is effectively reduced, and then that the unmanned aerial vehicle cannot directlyfall off or be damaged is guaranteed. The invention further discloses a civil unmanned aerial vehicle safety emergency slow descent intelligent parachute preparation system.

    本发明公开了一种民用无人机安全应急缓降智能备降伞的方法,通过以下步骤实现:主控盒通过姿态传感器和加速度计判断当前无人机的飞行姿态及加速度状态,当无人机姿态/加速度达到了触发判定条件或者接收到PWM触发信号时候,电子点火器点燃推进剂,推进剂燃烧并将降落伞包弹出伞舱,降落伞在下降过程中受到空气阻力,有效减缓无人机下降速度,进而保障无人机不会直接坠落损坏。还公开了民用无人机安全应急缓降智能备降伞系统。
