The invention belongs to the technical field of aircraft system design, and relates to an ejection seat safety pin warning method, which is characterized in that a microswitch is arranged on a central pull ring support of an ejection seat and is used for outputting a position signal of a central pull ring safety pin on the seat; a safety pin support with a microswitch is placed in an aircraft cockpit and used for outputting a position signal of a central pull ring safety pin on the safety pin support, logic judgment is carried out by collecting the position signal of the safety pin and a cockpit cover state signal, an undercarriage state signal, a brake state signal and a throttle lever state signal, and the safety of the central pull ring is achieved. When a pilot forgets to plug and unplug the seat central pull ring safety pin, the seat central pull ring safety pin alarm device sends out an alarm signal to remind the pilot to perform corresponding operation, and safety is improved.
本发明属于飞行器系统设计技术领域,涉及一种弹射座椅保险销告警方法,在弹射座椅中央拉环支座上设置微动开关,用于输出中央拉环保险销在座椅上的位置信号;在飞机座舱内放置带微动开关的保险销支座,用于输出中央拉环保险销在保险销支座上的位置信号,通过采集保险销的位置信号,与舱盖状态、起落架状态、刹车状态、油门杆状态信号进行逻辑判断,将判断结果发送给告警系统进行弹射座椅保险销告警,本发明用于飞行员忘记插拔座椅中央拉环保险销时,发出告警信号,提醒飞行员进行相应操作,提高安全性。
