A system for monitoring a pressure change within at least one compartment of an aircraft and operating a pyrotechnic device associated with a door latch, includes a securing mechanism arranged in an aircraft door that includes a pyrotechnic actuator and a latch bolt. The system includes the pyrotechnic actuator configured to move the latch bolt when the pyrotechnic actuator is actuated. The system also includes a pressure sensor configured to provide a pressure signal. The system also includes a controller configured to determine a pressure drop representing a decompression event. The system also includes an output driver configured to generate an output signal to actuate the pyrotechnic actuator when the controller determines the occurrence of a decompression event.
一种用于监测飞机的至少一个舱室内的压力变化以及操作与门锁相关联的烟火设备的系统,该系统包括布置在飞机门中的固定机制,该固定机制包括烟火致动器和闩锁螺栓。该系统包括该烟火致动器,被配置为当该烟火致动器被致动时移动闩锁螺栓。该系统还包括被配置为提供压力信号的压力传感器。该系统还包括被配置为确定代表减压事件的压降的控制器。该系统还包括输出驱动器,该输出驱动器被配置为当控制器确定减压事件的发生时产生输出信号以致动烟火致动器。
