The invention discloses an emergency self-power-supply control system and method for a helicopter emergency floating device, during normal power supply on a helicopter, the state of the helicopter emergency floating device is monitored, an energy storage large capacitor is charged for energy storage, and if a manual starting signal of a main/auxiliary manual switch or a water entry starting signal transmitted by a water immersion sensor is received during the period, the helicopter emergency floating device is started; if yes, controlling to activate the thermal battery to trigger the gas source equipment to start; when the machine is powered off or power cannot be supplied, the large energy storage capacitor discharges to achieve emergency self-power supply, and if a manual starting signal of the main/auxiliary manual switch or a water entry starting signal transmitted by the water immersion sensor is received during the period, the thermal battery is controlled to be activated so as to trigger the gas source equipment to start. When the helicopter is powered off or power cannot be supplied, the emergency floating device of the helicopter can still work normally for a certain time, opening of the emergency buoy can still be guaranteed during the period, and the water life-saving capacity of the helicopter is improved.
本发明公开了一种直升机应急漂浮装置应急自供电控制系统及方法,在机上正常供电时,监测直升机应急漂浮装置的状态、给储能大电容充电蓄能,期间若接收到主/副手动开关的手动启动信号或浸水传感器传输的入水启动信号,则控制激活热电池从而触发气源设备启动;机上断电或无法供电时,储能大电容放电实现应急自供电,期间若接收到主/副手动开关的手动启动信号或浸水传感器传输的入水启动信号,则控制激活热电池从而触发气源设备启动。本发明在机上断电或无法供电时,仍能让直升机应急漂浮装置正常工作一定时间,期间仍能保证应急浮筒的开启,提高了直升机的水上救生能力。
