摘　　要：发展一种健全的高安全性飞行锁控制系统解锁控制架构在民用飞机舱门电控中是相当重要的。飞行锁控制系统用于防止飞机在飞行过程中人为意外打开旅客登机门、服务门和应急门的操作。在适航审查活动中,定义了飞行锁控制系统在地面应急撤离阶段无法解锁的I类安全性事件。按照飞行锁控制系统实际使用需求和适航规章要求,设置较为宽松的解锁逻辑。为了实现飞行锁控制系统在应急阶段的高安全性要求,提高系统的鲁棒性和可靠性,在飞行锁控制系统中引入应急撤离系统控制信号和驾驶舱手动控制信号使用机制以提升应急撤离情况下的自动控制以及飞行员对飞行锁控制系统的控制权限。该项飞行锁控制系统设计将飞行锁控制系统功能研制保证等级由A级下调至C级,有效降低了研制成本和人员研制精力,同时提升了飞行锁控制系统的安全性,达到飞行锁控制系统的全面控制和精细化管理。It is very important to develop a sound unlock control architecture of high safety flight lock control system in civil aircraft door electric control. The flight lock system is used to prevent the aircraft from human deliberately opening passenger door, service door or emergency exit door during flight. In airworthiness certification activities, Class I safety events that the flight lock system fail to unlock in the ground emergency evacuation phase are defined. According to the actual use requirements of the flight lock control system and airworthiness regulations, a relatively loose unlock logic was set. In order to meet the high safety requirements of flight lock system in emergency situation and improve the robustness and reliability of system, emergency evacuation system control signal and flight deck manual control signal mechanism were introduced into the flight lock system to improve the automatic control in the case of emergency evacuation and the pilot’s control authority over the flight lock control system. The design of the flight lock system reduces the Functional Development Assurance Level(FDAL) of flight lock system from A to C, effectively decreases development cost and personnel development energy, and improves the safety of flight lock system to reach total control and precise management of flight lock system.
