令幕后故事 · 发表于 2012-10-29 16:50:30

The cockpit door has an electro-mechanically operated release system (CDLS) for the cockpit security. The cockpit door is in the locked condition when the CDLS is energized with electrical power. This electrical power comes from the normal busbar 204PP through the circuit breaker 1MQ at the circuit breaker panel 122VU.
If the CDLS is not energized with electrical power the cockpit door is in the unlocked condition.
The operation of the key pad 25MQ installed in the forward attendant panel 120RH causes the buzzer 23MQ to operate. This tells the cockpit crew that a person requests access to the cockpit.
The toggle switch 26MQ on the center pedestal panel 119VU sends a signal to the control unit 24MQ when it is in the UNLOCKED positon. The control unit 24MQ in the overhead panel 20VU then produces an output signal. This signal de-energizes the solenoids of the three electrical release strikes so that the cockpit door is in the unlocked condition .
If there is a sufficient loss of cabin pressure in the cockpit, pressure sensors in the control unit 24MQ operate. Then the electrical release strikes de-energize and the cockpit door is unlocked in the case of a rapid decompression.
If a malfunction occurs in the CDLS the subsequent indication lights come on:
-    the amber FAULT indication light 22MQ and the LED's CHAN 1 or CHAN 2 of the control unit 24MQ show that the applicable pressure sensor is unserviceable.
It is a normal system behavior that these lights may come on when the pressurization test of the fuselage is in progress. When the pressure decreases these lights go off and the CDLS is operative again.

-    the amber FAULT indication light 22MQ and the LED's TOP, MID or BOT STRIKE of the control unit 24MQ show that the applicable electrical release strike is unserviceable.

那个是压力传感器

驾驶舱门锁培训

图上面板的两个小孔分别连接两个传感器，那个是压差传感器，当驾驶舱气压低于客舱压力时，驾驶舱门锁自动开启，靠空气压差开门，平衡驾驶舱和客舱压力，是一个安全措施，面板上的频道12分别指示两个压差传感器的故障指示。
