The invention relates to a helicopter airbag triggering method and a device. The device comprises a sensor system, a controller and an independent power supply system, the sensor system comprises an acceleration sensor, a flight height sensor and a manual trigger switch; the controller is connected with the sensor system, and is used for obtaining signals of all sensors in the sensor system, sending out corresponding trigger signals after data processing, calculation and comparison, and opening helicopter safety airbags, and the independent power supply system is used for supplying power to ahelicopter safety airbag system in emergency. When a helicopter crashes uncontrollably in an emergency state at high altitude, a driver can turn on a manual trigger switch by himself/herself to inflate the air bag slowly, and the safety air bag is opened; when the helicopter collides at high altitude, the air bag is inflated at a high speed, and protection is provided for airborne personnel at thehighest speed; when the helicopter falls in an emergency state at a low altitude, the airbags are inflated quickly, and scare is avoided while protection is performed; when the helicopter impacts theground, inflation of the air bag at a high speed is realized, and buffer protection is provided quickly.

    本发明涉及一种直升机安全气囊触发方法及其装置,该装置包括传感器系统、控制器和独立电源系统,传感器系统包括加速度传感器、飞行高度传感器和手动触发开关,控制器与传感器系统连接,获取传感器系统中各传感器信号,并经数据处理、计算与对比后,发出相应的触发信号,打开直升机安全气囊,独立电源系统用于紧急情况下直升机安全气囊系统供电。直升机高空出现紧急状态不可控坠毁时,驾驶员可自行打开手动触发开关,向气囊较缓慢充气,开启安全气囊;直升机高空出现撞击,向气囊极速充气,以最快速度给机载人员提供防护;直升机低空出现紧急状态下坠,向气囊快速充气,防护同时避免惊吓;直升机撞击到地面,向气囊极速充气,快速提供缓冲防护。
