Electronic control for the operating mechanism of an aircraft door.
The invention relates to an electronic controller for implementing the kinematics of an aircraft door. The closing and opening of the aircraft door, whose components can be operated electrically, can be controlled electronically by using it. The door components are operated optimally and reliably (safely) in normal operation and under emergency conditions. In the case of known aircraft door types which are designed in accordance with the contact - or toggle lever - principle, the individual operating steps such as opening and closing or locking and unlocking, as well as the activation of an emergency slide, are carried out manually. Precise control of the kinematics of aircraft doors, which kinematics operate in accordance with a program which is stored in the memory of a CPU and coordinates the sequence of the operating steps, is not known for aircraft door controllers. The electronic controller for the kinematics of the aircraft door (1) consists essentially of a microprocessor unit (50) which is conductively connected to a drive system (59) located inside the aircraft door (1). An electromagnet (51) which implements the activation of a pneumatic opening cylinder for emergency opening of the aircraft door, a first and a second pressure sensor (52, 53) by means of which the pressure conditions of the relevant store for the pneumatic opening cylinder or for the emergency slide are monitored, a base valve (54) which ensures communication to a door opening system, a computer control system (55) which ensures communication to the cockpit display, and a screen monitor (63) are also conductively connected to the microprocessor unit (50). A first and a second panel (56, 57), by means of which a manually operated controller for the aircraft door (1) and the visual display of the current door status are implemented, are also conductively connected to the microprocessor unit (50). The microprocessor (50) implements the direct or indirect drive of the electronic drive system (59), which consists of a plurality of motors and/or motor groups. An energy source (58) which is connected to the microprocessor unit (50) ensures continuous DC supply to the controller. <IMAGE>
