Airplane power-driven cabin door safety control system and control method thereof

Abstract

The invention discloses an airplane power-driven safety control system and a control method of the airplane power-driven safety control system. A correct instruction can be given to an operator on the ground, and besides the power supply of a power-driven cabin door can be reliably cut off in the flight process. The safety control system comprises an external signal module, a sensor module, a sensor processing and controlling module and a power-driven cabin door controller. The external signal module is provided with a wheel load bus signal module, an engine idling signal module and a wheel load hardwire signal module. The sensor module is provided with a locking sensor, wherein the locking sensor is used for collecting a position signal of the locking position of the airplane power-driven cabin door. The sensor processing and controlling module is used for controlling whether to supply power to a relay or not on the basis of signals collected by the wheel load bus signal module, the engine idling signal module and the locking sensor in the sensor module. The power-driven cabin door controller is used for controlling the power-driven cabin door to be opened or closed on the basis of the wheel load hardwire module and a cabin door opening instruction.

Description

technical field [0001] The invention relates to an aircraft electric cabin door control system and a control method thereof, in particular to an aircraft electric cabin door safety control system used to prevent the aircraft electric cabin door from being safely operated on the ground and not accidentally opened during flight, and its control method. Background technique [0002] After experiencing two cargo door accidents in the 1990s, the FAA (Federal Aviation Administration of the United States) issued the FAR25-114 amendment in 2004, which put forward very strict requirements for the safety standards of the cabin door. [0003] In previous aircraft designs, electronically actuated electric doors did not provide reliable operating instructions, nor did they cut power to the doors in flight. Therefore, the operator of the electric cabin door cannot obtain accurate information on the status of the cabin door and a clear indication of the operation, and it is easy to make a...

Problems solved by technology

Therefore, the operator of the electric cabin door cannot obtain accurate information on the status of the cabin door and a clear indication of the operation, and it is easy to misoperate and damage the door lock mechanism of the cabin door, resulting in a dangerous situation during the air pressurization process

What's more serious is that in the previous aircraft design, the electric hatch was flying with electricity. Due to the logic error of the electric control system or other factors, it may cause the electric hatch to work during the flight and open the hatch, causing the aircraft to lose pressure and cause serious damage. as a result of
