The invention provides an automatic parachute throwing condition interpretation method for a parachute recovery unmanned aerial vehicle. The method mainly adopts the principle that whether a parachutethrowing instruction is sent out or not is determined by establishing a multi-condition comprehensive judgment mechanism in flight control software by utilizing an existing airborne component. The comprehensive judgment mechanism mainly comprises the following steps: judging whether the real-time overload or acceleration module value of the airplane is greater than a certain value and lasts for acertain time, and judging that the vertical speed value of the airplane is less than a given amplitude and lasts for a certain time. As long as any one of the conditions is met, a flight controller automatically sends out the parachute throwing instruction, and parachute throwing is completed. The automatic parachute throwing condition interpretation method for the parachute recovery unmanned aerial vehicle is low in cost, easy to implement, accurate in interpretation opportunity and high in success rate.
本发明提供一种伞降回收无人机自动抛伞条件判读方法,其原理主要是:利用现有的机载成件,通过在飞控软件中建立多条件综合判断机制,确定是否发出抛伞指令。上述的综合判断机制主要包括:判断飞机实时过载或加速度模值大于一定数值且持续一定时间,判断飞机的垂直速度值小于给定幅值且持续一定时间。只要上述任一条件满足,飞控将自动发出抛伞指令,进而完成抛伞。本发明所设计的伞降回收无人机自动抛伞条件判读方法,成本低,实现简单,判读时机准确,成功率高。
